BACKGROUND Various treatments of giant cell tumor of bone (GCTB) included in curettages and resections and with adjuvant are exerted, but the best treatment is controversial. The aim of the study was the identification of individual risk factors after various treatments in GCTB. METHODS A total of 179 patients treated for GCTB between 1998 and 2010 were concluded in the retrospective study. A...

Pathologic femoral neck fracture due to renal osteodystrophy is rare. We report the case of a young adult patient with chronic renal failure who presented with bilateral spontaneous femoral neck fractures due to renal osteodystrophy. The pathophysiology of renal osteodystrophy and the treatment of hip fractures in patients with renal failure is discussed.

We observed a patient with a giant brown tumor of the iliac bone due to hyperparathyroidism. There was a risk of pathologic fracture due to huge cysts produced by bone absorption. In hyperparathyroid crisis, control of severe hypercalcemia is difficult without resection of the parathyroid gland.

UNLABELLED Pathologic fractures of the proximal femur resulting from primary bone sarcomas are often difficult to treat and some are often not recognized resulting in inappropriate interventions prior to the correct diagnosis being made. The aim of the study was to identify factors determining the survival after pathologic fractures of the proximal femur resulting from nonosteogenic primary bon...

The authors report the case of a five and a half year-old-boy with symptomatic MRI abnormalities of the ischiopubic synchondrosis. The concept of "ischiopubic osteochondritis" is reviewed in the light of modern imaging, and the importance of its differentiation from different pathological entities such as osteomyelitis, tumour, fracture or other pathologic entities is recalled.

Bisphosphonates help prevent progressive bone mineralization loss and subsequent osteoporotic fractures. However, long-term bisphosphonate therapy paradoxically increases the risk of a unique injury called an atypical subtrochanteric femur fracture. Despite this, the benefits of bisphosphonates outweigh the risks, because far more pathologic fractures are prevented than induced. The early ident...

Primary hyperparathyroidism is due most often to a parathyroid adenoma secreting parathyroid hormone. Elevated PTH levels cause bone resorption, the formation of polyostotic lesions and a reduction in bone mineral density, predisposing to pathological fractures. The final stage of this disease is osteitis fibrosa cystica. The authors review the literature about osteitis fibrosa cystica and the ...

Complications of harvesting autologous bone graft from the iliac crest and tibia are well known; exclusive use of upper extremity donor sites in hand surgery has therefore been advocated. Six weeks of postoperative elbow splinting has been recommended after harvest of large proximal ulnar grafts. We report two cases of pathologic fracture of the proximal ulna complicating local bone grafting an...
