Predictors of early and late instability following conservative treatment of extra-articular distal radius fractures.
The purpose of this study was to identify radiological predictors of early and late instability following conservative treatment of extra-articular distal radius fractures. ⋯ An awareness of independent predictors of instability in extra-articular distal radius fractures is helpful in anticipating the final alignment outcome.

Comparative StudyIntramedullary fixation of pertrochanteric hip fractures with the short AO-ASIF proximal femoral nail.
The advantages of intramedullary fixation of pertrochanteric hip fractures over dynamic screw-plate devices in the clinical setting are still a matter of debate. We performed a case series study in a teaching hospital to analyse the results of the recent AO-ASIF proximal femoral nail (PFN). ⋯ In view of only one loss of reduction with varus collapse clearly caused by a technical error, we concluded that the PFN is a suitable implant for unstable fractures, but the high re-operation rate precludes its routine use for every pertrochanteric fracture.

Case ReportsGiant cell tumor of the distal fibula: fifteen-year result after en bloc resection and fibula reconstruction.
Giant cell tumor of the distal fibula is a very rare condition. The treatment of advanced tumors at this location can be challenging and has been described in the literature only in single cases. ⋯ We suggest the method to be worthwhile for treatment of this uncommon lesion in terms of recurrence and functional outcome.

Comparative StudyComposite implant of native bovine bone morphogenetic protein (BMP), collagen carrier and biocoral in the treatment of resistant ulnar nonunions: report of five preliminary cases.
Bone morphogenetic protein (BMP) has been shown to induce bone formation and union in long bone defects and nonunions. There are, however, no previous reports of BMP being used for ulnar nonunions. We report on five cases of resistant ulnar nonunions treated with a composite implant consisting of a biocoral frame, collagen carrier, and bovine BMP. ⋯ These preliminary results suggest that BMP-containing implants might be a feasible alternative or superior to autografting in the treatment of resistant ulnar nonunions.

Antegrade nailing of femoral shaft fractures combined with neck or distal femur fractures. A retrospective review of 25 cases, with a follow-up of 36-150 months.
Complex femoral fractures pose considerable therapeutic challenges to orthopedic surgeons. We present a retrospective review of 25 patients with complex femoral fractures treated with intramedullary locked nailing and supplemental screw fixation. ⋯ Femoral intramedullary nails with antegrade or retrograde options for insertion and different locking possibilities have extended the indications to include both diaphyseal and metaphyseal fractures. New nail designs, usually more expensive than the conventional nails, have been introduced into the market for this purpose. One has to keep in mind that antegrade, locked nailing of femoral shaft fractures combined with neck or distal femur fractures is a technically demanding but efficacious procedure. The success rate is high when the technique is meticulously implemented.
