Abstract Background: Moderate intensity continuous training (MICT) has been reported as an effective exercise on bone metabolism. However, very few studies have focused on high-intensity interval training (HIIT). The aim of this study was to investigate and compare the effects of HIIT and MICT training on bone density in middle-aged rats.Methods: 30 male Wistar rats (16 weeks old) were randomly divided into three groups: control, MICT and HIIT. Both test groups completed 8 weeks (5 sessions per week) of treadmill training in which the HIIT group performed 10 sessions of running at a speed of 35-47 m/min with a 2-minute active recovery, and the HIIT group ran continuously for 10-45 minutes at a speed of 15-20 meters per minute. The body composition and bone mineral density in the whole body were evaluated through Dual Xray absorptiometry (DXA) at the beginning and after the intervention. The data was analyzed using SPSS software and one-way analysis of variance and Tukey's post hoc tests.Results: After 8 weeks of intervention, BMD of the whole body and femur increased significantly in both groups (p0≥0.05), although the observed change was greater in the HIIT group (p≥0.05). In addition, in the case of BMD of the lumbar vertebra, no significant difference was observed between all three groups after the intervention (p≤0.05).Conclusion: These findings show that a period of HIIT and MICT training can improve bone density in middle-aged rats and compared to MICT, HIIT had more benefits on bone density.

Background: Ankle arthrodesis is one of the major surgeries for the treatment of advanced osteoarthritis of the ankle joint. There are various techniques available for ankle arthrodesis and each technique has unique advantages and disadvantages. The aim of the present study was to evaluate the results of ankle arthrodesis with two this different approaches.Methods: The medical records of the patients who were admitted for ankle arthrodesis and treated by a single surgeon from January 2015 to January 2020 were reviewed. The patients were recalled for re-evaluation after a mean follow-up of 19 months. Functional outcomes were assessed using validated AOFAS Ankle-Hind foot score, Manchester-Oxford Foot Questionnaire (MOXFQ) and visual analog scale (VAS) score for pain. The collected data were recorded in a pre-designed checklist and then analyzed using SPSS software.Results: A total of 32 patients, 18 men and 14 women with a mean age of 46.7 years were included in the study. 67.6% had history of ankle fractures. Anterior approach was used in 24 patients, 75%, and the rest of the patients had surgery with lateral approach (25%). The most common instrument for arthrodesis was concomitant use of plate and screws in 18 patients (56%). Union occurred in 28 patients (87.5%) within 11.1 weeks after the surgery. The AOFAS score increased significantly and MOXFQ and VAS scores decreased significantly following the surgery (p<0.001 for each). Advanced age and intramedullary nail were related to prolonged time to union (p<0.05). Surgical approaches (either anterior or lateral) had no association with AOFAS, MOXFQ, and VAS scores. Non-union was seen in 4 patients (12.5%) and deep infection in 3 patients (9.3%) after ankle arthrodesis.Conclusion: The study results showed that, this surgery could improve patients’ pain and function with relatively low post-operative complications.

Medical research has always been a matter of health, and it is also important in sports, especially martial arts, which are associated with more injuries and injuries caused by exercise or during exercise. Therefore, scientific studies can be used to identify and identify these injuries and injuries. So far, there have been many studies in the field of injuries and sports injuries, in most of these studies, statistical methods and case studies have been used. In this research, we use a management decision-making method based on the principles of mathematical modeling to identify the injuries and damage caused by martial arts. The advantage of this method is that, based on paired comparisons and using judgments of experts and orthopedic specialists, the factors and the effect of the relationships between them can be identified. Hence, this method can detect damage to organs and joints, even with the degree of severity and importance of them.

Background: Postoperative pain following total hip arthroplasty (THA) impacts patients' rehabilitation and quality of life. Although gabapentin has been widely used for pain control, its effectiveness in hip arthroplasty is not well established. The aim of our systematic review is to evaluate the effect of gabapentin on postoperative pain after THA.Methods: A systematic search was conducted in three databases: MEDLINE, PsycINFO, and Embase, through OVID, using the keywords gabapentin, pain, and hip arthroplasty, with no restrictions on language or publication date. To evaluate the quality of the articles, the Cochrane Collaboration tool was used.Results: Five studies, including 728 patients, were included in our systematic review. Gabapentin 600 mg was used in three and 1200 mg in two studies. The results of these studies showed that gabapentin had no significant effect on pain or morphine consumption after THA. Besides, gabapentin use was associated with side effects such as rash, nausea, headache, vomiting, and pruritus.Conclusion: Gabapentin does not decrease pain or morphine consumption after THA. However, future studies with a larger sample size and longer follow-up period are required.

Background: Most reports on the underlying problem of complete hip replacement are related to its loosening. Several important factors such as the implant features, the replacement process, the use and amount of bone cement, and the patient's lifestyle affect the loosening. The aim of this study was to provide an analysis of the dynamic stresses and strains at the interface between the bone and the implant in different phases of walking in order to determine and develop biomechanical parameters of loosening.Methods: A two-dimensional model including femur and its artificial joint has been used in numerical simulation with ADINA software based on finite element method. There is a dynamic load applied to the joint head corresponding to the normal walking cycle of a person with 75 kg weight.Results: The results show a difference between stress and strain in the medial and lateral edge of the bone-implant interface, which indicates a risk area for loosening. The amount of strain difference at the interface with about 1.6% and stress reaches about 5.7 MPa.Conclusion: The greatest strain difference occurred in the lowest area of the implant stem, which indicates the possible occurrence of separation in implant loosening. This information can also be used in surgical strategies for hip replacement and is also important for optimal mechanical design of the implant.

Background: The aim of this study was to compare corticosteroid injection and corticosteroid injection with needle release (Pie-crusting) method in the treatment of plantar fasciitis in patients with heel pain.Methods: The present study is a randomized clinical trial. The study population included patients with heel pain who had referred to a teaching center with plantar fasciitis for treatment during the years 2020-2019. The patients were randomly divided into two groups: corticosteroid injection and corticosteroid injection plus Pie-crusting method. The patients were visited again in the third (T1), sixth (T2), twelfth (T3) and twenty-fourth (T4) weeks post treatment, and the severity of pain and ankle and foot score (AOFAS) were determined at each visit. The data of this study were analyzed with SPSSv.24 software.Results: 89 patients (46 in steroid injection group and 43 in "pie-crusting" group) were examined. Patients in the two groups were similar in terms of age, sex and body mass index. The two groups showed a significant difference in terms of VAS of pain only in the T4. The AOFAS in the T2 (p=0.039), in the T3 (p>0.001), in the T4 (p>0.001) statistically significant differences were reported. Comparing the angle of inclination of the calcaneus, there was no statistically significant difference between the two groups in the T4.Conclusion: The results of this research showed good results in use of combination of corticosteroid therapy and "pie-crusting surgery" for plantar fasciitis.

Background: There are some relatively definite indications for fixing these problems which can be as the surgery with Osteotomy and the deformation and making the bone fixed in new location. There are so many techniques in this field with respect to the surgery and the kind of osteotomy, and with respect to the kind and fixation tool.Genovalgum is usually a disorder in femur distal and this point can be repaired by osteotomy. From the past, the blade plate is an attractive option for the fixation which can be harder than newer methods like lockable blade-plates for the younger surgeons. In this research, our goal was to present a new design of blade plate for more easiness in tool installation and test the finite element for making sure of the effectiveness of the new tool. The goal of this research is to design a modular sample of blade plate and the biomechanical comparison of these two states in the finite element form. In this research, the biomechanical behavior of these two methods with pseudo-static loading on the made model in the finite element software. Methods: The CT-Scan images were transformed to Mimics software. Then, the model under biomechanical analysis was placed in abaqus19.0 software in pseudo-static form. The bone was considered as orthotropic and stainless-steel implant. Results: In the comparison of the tension of blade plate and bone, the tension on the blade-plate and bone has been reduced in modular blade plate which is possibly related to the energy waste in the connection of blade and plate. The strain of modular blade plate is significantly less than the older blade plates, but the strain of the bone without orthosis is much more similar to the previous blade plate with respect to the strain of the bone

Background: The purpose of this study is to investigate the results of surgical treatment for hallux rigidus using the Weil osteotomy method in grade III patients with this disease.Methods: This quasi-experimental study involved a single-group intervention "before and after" the surgery. The research population consisted of patients with grade 3 hallux rigidus. The data collection tool used in this study was a checklist based on clinical examinations that evaluated joint movement in both plantar and lateral directions, as well as the Visual Analog Scale (VAS) to measure pain. The range of motion and pain level of the metatarsophalangeal (MTP) join were investigated and recorded before the operation and 1, 3, and 6 months after the operation. All this information was entered into SPSS software version 26.Results: The study groups included 8 (22.9%) male and 27 (77.1%) female patients, with an average age of 77.1 ± 12.17 years. The amount of pain decreased significantly (P=0.00) at the one-month and three-month follow-ups after the intervention, and the amount of passive movement of the joint in the plantar directions significantly increased from one month to three months after the intervention (P=0.00). 17 patients (48.6%) took up to two weeks after surgery, 10 patients (28.6%) between two to four weeks, and 8 patients (22.9%) more than one month to recover the mobility. The average joint space of the patients after the operation in plain radiography was 3.6 ± 0.46.Conclusion: : The Weil osteotomy surgery in hallux rigidus patients showed a significant decrease in pain level, and also a significant increase in joint motion and improvement in the average joint space in short term.

Background: Essex-Lopresti injury (ELI) is one of the rare injuries of the elbow area, which includes fracture of radius head, disruption in the interosseous membrane of the forearm (IOM), and distal radio-ulnar joint dislocation. This happens as a result of transverse pressure on the elbow and forearm when falling down or when high energy is applied.Methods: In this study, we introduced a 40-year-old patient who suffered both bone forearm fracture in addition to the above injuries. First, the patient underwent both bone forearm ORIF surgery, and then fixation of radius head and distal radio-ulnar joint reduction and fixation.Results: After six months, the patient has 20 degrees of motion limitation only in the pronation state, and the joint’s motion range in other joints is complete.Conclusion: In general, the Essex-Lopresti injury (ELI) is one of the rare hand injuries that are difficult to diagnose with simple radiographs and requires great care.

Background: To improve the education of orthopaedic residents and enhance patient care in the Iran's healthcare system, it is necessary to gather information about the current status of scientific, practical, and research-based education for residents.Methods: The research project initially focused on examining the executive curriculum in 14 centers affiliated with 6 different medical universities. Subsequently, an investigation was conducted into human resources, infrastructure, operating room facilities, educational and research outcomes, as well as the regular implementation of practical examinations to evaluate the performance of residents during their residency years. All the aforementioned aspects were covered using a comprehensive questionnaire, which was distributed via the "Formafzar.com" website as a link to the heads of departments in these centers by the Iranian Orthopaedic Association. The relationship between facilities and equipment and passing the future specialized orthopaedic board examination was also evaluated.Results: Among the examined centers, only 20% adhered to the criteria of Iran educational curriculum in all aspects of human resources, education, and research.Conclusion: a regular evaluation of teaching methods used by international centers and the national curriculum is necessary for orthopaedic training centers in Iran. Additionally, regulatory systems should monitor the training process of orthopaedic residents to standardize services, equipment, and educational programs in the country.

I have had concerns about a possible decline in the Orthopaedic Residency Program in the recent years. I, therefore, looked at the residency programs in few other countries, namely Canada, England, Russia, Australia, India, and Saudi Arabia. The following fields were looked up and compared with the present situation. In Iran: resident selection method, period of residency training, working hours, daily notebook and medical services; mandatory in-training exams; the amount of supervision by the attending staff and mentors; From the six investigated countries, all but Russia had had almost similar orthopaedic residency training programmes. The major difference, however, were in the residency training years that were between 5 to 10 years, and the maximum allowable working hours which varied between 56 to 80 hours per week Orthopaedic residency training in Iran with the approval of the Ministry of Science, the Iranian Orthopaedic Residency Program was established in 1973, at Shafa Yahyaian Hospital simultaneously Shiraz University. The residency curriculum was formulated using the American Academy of Orthopaedics, as a framework. There were subtle differences. Though, i.e., the residency period in America is 5 years, but the Iranian program is 4 years. At its core the programs were equal in caliber, as evidenced by the exam results. The Iranian in-training exams used questions mailed from America. After completion, the exams were sent to the American Academy of Orthopaedics for evaluation. It was reported that the exam results were on par with the average American trained resident. The implementation of Curriculum of the Academy, at the Shafa Training Center, provided a solid foundation for several decades of growth and excellence in Orthopaedic Residency. In more recent years, however the absence of curriculum; the proper attending supervision in the educational centers; and the lack of supervision by regulatory institutions have caused a decline in the quality of the programs. The 4-year residency period has been reduced to 3.5 years. Proper record-keeping in "by books" for the number of surgeries a resident performs is not possible. Supervision of attending staff has gradually decreased to negligent levels. In all the programs examined, daily notebooks and attending supervision are paramount. In 2010, the Iranian Presidential Science Auditing Department audited the current state of the Orthopaedic Residency Program. It was reported that Orthopaedic residents were only taught 20% of the orthopaedic curriculum. In teaching hospitals, 80% of beds are filled with emergency patients. Contrary to the best practices, the staff imposes the emergency burden on the residents. We found only one residency training center that covers residents 24/7 (Shafa Yahyaian Training Center). In other cases, there is no proper supervision. There are a number of factors contributing to the decline and degradation of residency education: lack of supervision by the orthopaedic board; nonadherence of educational centers to the implementation of educational curriculum; lack of attending supervision; and also the emergence of fellowship programs.

Background: Congenital kyphosis is a spinal deformity resulting from disruption in the formation of the anterior part of the vertebrae on the sagittal plane during early fetal development. Understanding demographic trends and associated anomalies in affected individuals within specific regions and countries is pivotal for tailoring more suitable treatment approaches within these patients.Methods: This retrospective cross-sectional study was conducted on 108 patients referred to Shafa Yahyaian Hospital in Tehran between 2010 and 2019. Demographic and radiological criteria were assessed in all patients who underwent surgery for congenital kyphosis at this hospital. Parameters such as age, gender, BMI, presence of cardiac, urogenital system, and spinal anomalies, kyphosis type, as well as Cobb's angle before and after surgery, were gathered, reviewed, and analyzed from patients' records.Results: Of the cohort, 74 patients were categorized as congenital kyphosis type 1, 21 as type 2, and 13 as type 3, encompassing 69 female (63.9%) and 39 male patients (36.1%). The mean age at the time of examination and symptom onset was 6.5 years, while the mean age at the time of surgery was 16.5 years. Notably, 38 patients exhibited a cardiac anomaly, 14 had genitourinary system anomalies, and 39 presented with spinal anomalies. A statistically significant correlation existed between the presence of a cardiac anomaly and the type of congenital kyphosis, with type one exhibiting a markedly higher incidence of cardiac anomalies compared to the other two types.Conclusion: The findings revealed a higher frequency of type 1 congenital kyphosis. Moreover, patients with type 3 congenital kyphosis underwent surgery at a significantly younger age than those with the other two types, potentially attributed to its higher progression rate. Spinal cord, cardiac, and genitourinary tract anomalies were respectively observed as the most prevalent anomalies among the patients.

Background: Diagnosis of associated midfoot fractures in Lisfranc injuries is important for proper treatment. We aimed to describe frequency of different types of Lisfranc injuries in surgically treated cases and to find the accuracy of non-weight bearing radiographs to determine associated midfoot fractures.Methods: In a retrospective study, preoperative non-weight bearing plain radiographs and CT studies of 118 surgically treated Lisfranc injuries were evaluated by 2 orthopedic surgeons. The sensitivity and specificity of fleck sign, fractures of metatarsal bases, cuneiforms, navicular, and cuboid were calculated. Results: Among 118 patients with the mean age of 35.0±15.7 years, most were male (77.1%). The most common type was Myerson type B (44.1 %) followed by D2 (40.7%). Fractures of the second metatarsal base (87 patients, 73.7%), the fleck signs (85 patients, 72.0 %), and fractures of the third metatarsal base (65 patients, 55.0 %) were the three most frequent injuries. Oppositely, fractures of the fifth metatarsal base (5 patients, 4.3%), middle cuneiform (14 patients, 12.0%), and navicular (15 patients, 12.7%) were the three least common associated midfoot fractures. Plain radiographs could not show high sensitivity to distinguish associated midfoot fractures in Lisfranc injuries with the highest for the second metatarsal base fractures (78.2%). The maximum specificity was for fractures of the first metatarsal base (100%). Conclusions: Non-weight bearing radiographs of the foot cannot detect all associated midfoot fractures particularly fleck sign. Therefore, preoperative CT scan is highly recommended.

Objectives: The prevalence of atypical femoral fractures in the elderly population is increasing worldwide, including in Iran. Left untreated, these fractures can lead to disability and reduced quality of life for patients.This study aims to evaluate surgical outcomes in patients with atypical femoral fractures.Methods: This case-series study was conducted at Rasoul Akram Hospital on patients with atypical femoral fractures who underwent surgery from 2013 to 2020. Demographic and clinical information, including gender, age, fracture site, type of surgery, infection, and postoperative walking ability, as well as modified Harris Hip Score (HHS) and Numeric Rating Scale (NRS) scores, were collected at one month and one year after surgery.Results: Among the 30 participants in this study, 24 (80%) were female. The mean age of the patients was 68.66 ± 11.03 years. Of the patients, 46.7% underwent plate surgery, 26.7% had intramedullary nailing, and 26.7% underwent PFNA surgery. After surgery, 6 patients (20%) regained the ability to walk, 20 were able to walk with a cane or walker, and 4 could not walk. The NRS score of patients decreased by 2.80 ± 1.20 points after surgery, while the modified HHS score increased by 9.13 ± 22.56 (P value >0.05). After surgery, 13.3% of patients developed an infection. The type of surgery did not significantly affect patients' pelvic function or pain after surgery (P value> 0.05).Conclusion: The rate of complications and postoperative infections in surgeries for atypical femoral fractures is higher than for typical fractures, and the postoperative mobility and satisfaction of these patients are lower than usual.

Introduction& Purpose: Physical activity decreases at the beginning of adolescence, so organized physical activity at school plays an essential role in promoting the health and proper physical development of students. The purpose of this study was to investigate the effect of eight weeks of calisthenics training on core stability, muscle strength, static balance and trunk proprioception of male teenagers. Methods: In this semi-experimental study with a pre-test-post-test design, 40 male high school students aged 15 to 18 in Zavareh city were selected as a sample and randomly divided into two groups: calisthenics training (n=20) and control (n=20). The experimental group received calisthenics training for eight weeks, three times per week, for 60 minutes each session. Before and after the eight-weeks training, static balance, core stability, muscle strength and trunk proprioception were measured using the Stroke balance test, McGill test, chest press, leg press, rowing and error rate of the trunk reconstruction angle at 45° respectively. Results: The results of the independent t- test showed that eight weeks of calisthenics training increased the amount of static balance (p<0.0001), trunk proprioception (p<0.0001), core stability in trunk flexion (p<0.0001), and muscle strength in the rowing and leg press test (p<0.05) significantly. Conclusion: Overall, the findings from the present study suggest that following an 8-week participation in calisthenics training, trunk proprioception, core stability in flexion, muscle strength and static balance improved in teenagers, therefore, this type of exercises can be used along with other types of exercises or as a suitable alternative in schools.

Introduction:Genu varum is a type of knee deformity. In this deformity lower limb mechanical axis, moves inward to the knee centre. In genu varum mechanical axis usually lies through the medial of the knee joint. In this deformity, the patient's lower limbs become bow shape. One of the best techniques for genu varum correction is high tibial osteotomy that this procedure can change some index include posterior tibial slope (PTS), and insall-salvati index (ISI).Method:Our study was a cross-sectional study performed on patients with genu varum before and after a step cut of the high tibia osteotomy. The method of examining the posterior tibia slope was that before and after the high tibia osteotomy by Step Cut-MCL sparing method, a simple radiographic image in true lateral view (True lateral) was taken from the knee of patients. The significance level of P Value <0.05 was considered. Result:In this study 21 patients ( 11 male and 10 female ) were enrolled. Mean age was 36.19 ± 10.17 year-old. Mean PTS pre operation was 11.48 ± 1.94 degrees and post operation was 11.48 ± 2.15 degrees. Conclusion:In our study, PTS increased after HTO that this increase was not statistically significant difference between men and women. In addition, we showed that this increase did not have significant relationship with age and BMI.

Background: Osteoporosis, referred to as a " silent epidemic," is a skeletal disease with decreased bone density. This problem has no symptoms, but the most common result is fracture. According to the reported result, this disorder in Iran is more than 4% in men and more than 7% in women, while in the age of over 50 years, this statistic is significant and reaches more than 10% in both sexes. Considering this problem and the need to predict the conditions to change and treat it, it was decided to investigate this study of osteoporosis in people in a tertiary trauma center.Materials and methods: In this study, 113 patients over 65 year old age admitted to the emergency room of Sina Hospital were examined by and subjected to BMD osteoporosis examination, and also the demographic examinations of the patients were recorded through interviews and examination of hospital records, and were finally subjected to statistical analysisFindings: The age of the examined patients was 75.8 years and 67.3% were in the group over 70 years old. 44.2% of the studied population were women and 57.8% were men. 31 patients (27.4%) had a history of fracture. Alcohol consumption and smoking were reported in 3.5% and 31.9% of cases, respectively. In addition, there are 6 patients (3.5 percent) taking drugs on bone density, which in some cases were from the corticosteroid group.The fracture status of the patients was in 61 cases (54%) in the lower limb and in 52 cases (46%) in the upper limb. A total of 76 patients (67.3%) have osteoporosisConclusion: This study found that about two-thirds of the patients who suffer limb fractures in old age have osteoporosis.

Purpose of Review: Tendinopathy, also called tendinitis, is a common issue in musculoskeletal consultations. Tendon healing is inferior to normal due to low metabolic rate and poor vascularity. R. damascena has anti-inflammatory, antioxidant, and healing effects. This study aims to investigate R. damascene's effects on Achilles tendon injury using histopathology and biomechanical evaluations.Materials/Methods: Wistar rats were divided into seven groups, including a control group and three groups with tendinitis, that were given different doses of Hydroalcoholic Extract of R. damascene (HERD) (250, 500, 1000 mg/kg) intraperitoneally. Dexamethasone and Vitamin E were used in the reference groups. The Achilles tendon was injured, and the extract was administered for 20 days. Histopathological assessment and antioxidant activity were determined by serum malondialdehyde levels and ferric-reducing antioxidant power assays on days 10 and 20.Results: Different dosages of HERD, particularly 1000 mg, improved inflammatory intensity, angiogenesis, fibroplasia, and complete tendon regeneration on the 10th and 20th days after the injury, while also reducing unsaturated fatty acid peroxidation and increasing the whole serum's antioxidant capacity on the 20th day.Conclusions: After a thorough review, it can be concluded that HERD is an effective anti-inflammatory agent and analgesic for preventing and treating tendinitis. Furthermore, it has been deemed safe and well-tolerated, making it a promising option for those seeking relief from the symptoms of tendinitis.

Introduction: Knee osteoarthritis often causes disability due to the pain it causes and affects a person's quality of life.The purpose of this study is to investigate the effect of ankle-foot-orthosis with and without lateral wedge on pain, function and displacement of the center of pressure in patients with the medial compartment knee osteoarthritis.Methodology: The research method was quasi-experimental with a pre-test and post-test design. This study was conducted on patients with medial compartment knee osteoarthritis in the age range of to years as available sampling. Demographic information and Womac questionnaire were completed and the displacement of the center of pressure in the internal-external plane was recorded by the Kistler force plate device, in three situations: bare feet, ankle-foot orthosis with lateral wedge and ankle-foot orthosis without lateral wedge. The obtained data were analyzed using SPSS software. Shapiro-Wilk test was used to check the conformity of distribution of quantitative variables with normal distribution. According to the normality (p>0.05), variance analysis tests, multiple comparisons and generalized linear models were used for data analysis.Results: patients participating in this study were examined in three situations, and the pain of the patients in the state of using the orthosis with the lateral wedge was significantly reduced (p=), the function of the patients was better in the state of using the orthosis with the lateral wedge. (p=), but the displacement of the center of pressure in the case of using the orthosis without wedge had a significant decrease (p=).Conclusion: the use of an orthosis with an lateral wedge was effective in improving pain and function, but the use of an orthosis without an wedge led to a reduction in the displacement of the center of pressure in the internal-external plane. Therefore, it will probably reduce the knee adduction moment.
