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: Percutaneous vertebroplasty as an effective and relatively new treatment can strengthen broken vertebrae and reduce the pain of osteoporotic fractures. The Present study was conducted to assess the results of such treatment in osteoporotic vertebral fractures.Methods: In the present study, all the patients with osteoporotic vertebral fractures, having undergone vertebroplasty were studied by VAS before and after vertebroplasty. Complications after vertebroplasty (infection, nerve lesion, extra vertebrae cement leakage, cement-to-lung leakage and adjacent vertebrae fracture) were documented. Statistical data were entered into SPSS statistical software version 24 and statistical analysis was performed using Chi-square and independent t-tests.Results: Of the 40 evaluated cases, 10 (25%) were male and 30 (75%) females. The mean age of patients was 76.26 years. The mean of Visual Analogue Scale before vertebroplasty was 8.06, and after vertebroplasty was 1.34. The observed side effect was extra vertebrae leakage of cement, which was observed in eight cases (16%). No case of infection, nerve damage, and cement leakage into the lung or adjacent vertebral fracture was observed. Based on the analytical evaluation, there was no statistically significant difference between the mean of Visual Analogue Scale before vertebroplasty considering gender (P = 0.485) and age (P = 0.134). In addition, there was no significant difference between the mean of Visual Analogue Scale after vertebroplasty considering gender (P = 0.325) and age (P = 0.809). However, the mean of Visual Analogue Scale after vertebroplasty had a significant reduction in comparison to before vertebroplasty (P=0.0001). The second lumbar vertebra has been the most commonly involved vertebra.Conclusion: Based on observed results, percutaneous vertebroplasty can reduce the severity of pain in patients with osteoporotic vertebral fractures.

In recent years, spinal fusion surgery has become one of the most common treatments for spinal cord injuries, while the interbody cages, which replace the damaged interbody discs in the surgeries, have undergone extensive changes in design and material. These changes are quite visible, ranging from plain titanium cages made using the conventional manufacturing methods to customized porous titanium cages, which are made using additive manufacturing technology, or titanium-coated polymer cages. Among all the materials used in manufacturing the interbody cages, PolyEther Ether Ketone (PEEK) and titanium are the most common ones. Each of these two has its own advantages and disadvantages. Several studies have compared these two materials, mostly based on the two characteristics of subsidence and fusion rates. The present study performed a comprehensive review of the published clinical studies comparing the titanium and PEEK cages in order to make a comprehensive evaluation of these two. According to the reviewed studies, both materials had relatively similar results in subsidence rate, with no significant difference. However, it was shown that the titanium cages had a better fusion rate and subsequently were more likely to be successful in the clinical settings than the PEEK cages.
