Background: The final diagnosis of the tumors depends on the biopsy and the pathology result. The musculoskeletal tumor biopsy can be performed either by core needle biopsy or by open biopsy technique. The procedural cost is lower and the technique is simpler in core needle biopsy, but tissue sample may not be enough. In this study, we will compare the results of core needle biopsy with open biopsy in musculoskeletal tumors. Methods: In a prospective study, 75 patients with skeletal lesions were scheduled for open biopsy. A needle biopsy was also done before starting the operation in the same operating session. The pathology reports of core needle biopsy and open biopsy were then compared. The final pathology report following the definitive surgery was also compared with either of those two biopsy techniques. Results: The diagnostic accuracy of core needle biopsy for skeletal tumors was 77.2%. The value for benign tumors was 69.2%, for primary malignant tumors 82.7%, for tumor-like benign lesions 50%, and for metastatic tumors 100%. The accuracy of open biopsy was 100% for all tumors. Conclusion: Needle biopsy is an accurate and low cost method for diagnosis of skeletal tumors, but possibility of failure is present in very few cases.

Background: Supracondylar humerus Fracture is among the common upper extremity fractures in children. In certain types of fractures of circumstances that open reduction becomes necessary the best surgical approach is debatable. We would like to report our prospective study between posterior and lateral surgical approaches in type III supracondylar fractures. Methods: In a case series study, 87 children from birth till 18 years old, with type III humerus fracture were randomly selected for open reduction and pinning 43 through lateral and 44 posterior approaches. With a 6-months follow-up, elbow range of motion, complications and radiographic parameters related to :::union::: type were evaluated. Results: Posterior approach was a faster surgery. Ranges of motion after 1 and after 6 months were more restricted in posterior approach. Baumann and carrying angles were closer to normal in a higher percentage in posterior approach. Varus and valgus mal:::union::: or joint stiffness rates or infection were similar in the two groups. Conclusion: The two approaches were similar for postoperative complications. Better range of motion was achieved in the lateral approach, and a more anatomical :::union::: in the posterior approach.

Background: Distal radius is the most common site of fracture in older postmenopausal women, with a lifetime risk of 15%. Evidence exists for its association with osteoporosis. Osteoporosis can be detected by measuring the bone mineral density (BMD) of the lumbar spine with dual energy X-ray absorptiometry. Low BMD of the lumbar spine or hip is a strong predictor for future vertebral deformity and hip fracture. Elderly women with distal radial fracture are not investigated for osteoporosis on a routine basis. The aim of the present study is to evaluate the relationship between distal radius fracture and the BMD of the lumbar spine, and to investigate the need for osteoporosis screening in elderly women with a distal radius fracture.Methods: A prospective study was performed in a hospital in Mashhad in 2004-2005. In 104 women (mean age, 66.9 years) with a distal radius fracture, BMD of the lumbar spine was assessed. A biosphosphonate was prescribed when osteoporosis was diagnosed, and the BMD was reassessed after 2 years of treatment.Results: A low BMD was found in 87 patients (83.65%). Osteoporosis was diagnosed in 46 (44.23%) and osteopenia in 41(39.42%) patients. Only 17 cases (16.23%) had normal bone density. The mean T-score of the lumbar spine was –2.10 (±1.06). The BMD in patients treated with bisphosphonate medication increased from T-score of -2.88 to -2.55 in 2 years (p < /em>
