Background: Nowadays, bone grafting is used in both human and veterinary orthopedics to stimulate fracture healing, accelerate joint ::::union::::, and to restore bone defects. In such procedures, orthopedic surgeons are searching to favorable substitute for autograft bone. The purpose of this study is evaluation of theranekron and hydroxyapatite effects on bone healing in rabbit model.
Methods: First, 20 rabbits were prepared and they were divided into four groups of five. In the group of theranecron, theranecrone was injected to the bone defected site on days 3, 7, and 10 after surgery and one of the group was left empty as control group and in the third group combination of the theranekron and hydroxyapatite was filled in the defected site and in the final group hydroxyapatite was implanted alone. Radiographs from rabbit's hand after surgery were taken on days 14, 28, 42, 56 in lateral view. At the end of the study, histopathological samples were taken from injured area of radius.
Results: In radiographical and histopathological evaluations the group of theranekron-hydroxyapatite had the best performance in healing criteria and the control group was the weakest group.
Conclusion: theranekron group and theranekron –hydroxyapatite groups were better than two other groups in bone healing criteria by radiological and histopathological evaluation.

The distal radius is frequently affected by primary bone tumors, and is a
common site for occurrence of giant cell tumor. Giant cell tumor at the
distal end of the radius can be treated by various methods. Small lesion can be
treated by curettage and filling bone defect by autogenous bone graft or
allograft, or bone cement. Large lesion that involved articular surface can be
treated by wide resection and reconstruction with osteoarticular graft from
proximal fibular. This report presents a 42 year-old lady that was treated with
osteoarticular fibular graft for her recurrent distal radius giant cell tumor.

Background: Kienbock disease resulting from avascular necrosis of lunate bone leads to pain and disability in young active patients. Radial shortening is one of the treatment methods in this disease. In this study, we evaluated the mid-term results of treatment of Kienbock using radial shortening. Methods: In a retrospective study, 9 males and 6 females with Kienbock disease with average age of 28.6±9.37 years who had undergone radial shortening, were examined in a teaching hospital in Tehran-Iran. There were 2 patients in stage II, 5 in IIIa and 8 in step IIIb of Lichman’s class. In a mean follow-up of 5±2.44 years, these 15 cases were evaluated for wrist motion and gap strength and also with quick-DASH score. The radiograph Stahl index and carpal height ratio were also assessed. Results: Pain and range of motion improved and grip strength was favorable in 13 patients. Quick-DASH score was 8.5±.84 in patients with stage II, 12.72±5.09 in stage IIIa, and 27.57±18.87 in stage IIIb. Stahl index and carpal height ratio were the same in patients with stage II, but significantly decreased in other patients. Kienbock disease progressed in 2 cases. Conclusion: Radial shortening can relief clinical symptoms, even in stage III and IIIb of Kienback diseases, although the disease X-ray show radiographic worsening.

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>
