Review Comparative StudyShaft fractures of the clavicle: current concepts.
Fractures of the clavicle are common and have been typically addressed to nonoperative treatment. Favorable results, which predominantly were achieved in the young and adolescents, were supposed to be usual in midshaft clavicular fractures. However, in the presence of comminution or complete displacement, especially when occurring in females or elderly patients, there is a marked risk of nonunion, malunion, and poor outcome. ⋯ Plate fixation and intramedullary stabilization seem to be equally favored. Though, indications for operative management remain controversial. Further prospective randomized comparative clinical trials are necessary for a well-founded risk-benefit analysis.

Comparative StudyHigh revision rate after treatment of femoral neck fractures with an optionally (un)cemented stem.
The advantages of uncemented and cemented components in hip arthroplasty have been subject of debate. We have studied on a hemiprosthesis, which can be optionally implanted with or without cement. Since the stem geometry and surface in cemented arthroplasty differs from the uncemented one and cannot be fused into one general design, we hypothesised that this hemiprosthesis used without cement has a considerable high revision rate, based on aseptic loosening. ⋯ Because of the rather high revision rate, the authors advice not to use this hemiprosthesis without cement.

Anterior knee pain following the lateral parapatellar approach for tibial nailing.
Anterior knee pain after intramedullary nailing of tibial shaft fractures is a common clinical problem, with various etiologies. We have used a lateral parapatellar approach with atraumatic elevation of the infrapatellar fat pad to expose the starting point. Our hypothesis was that this approach leads to a low incidence of knee pain. ⋯ The modified lateral parapatellar approach with careful dissection of the fat pad may significantly reduce anterior knee pain after intramedullary nailing of the tibial shaft.

The anterior center edge angle in Lequesne's false profile view: interrater correlation, dependence on pelvic tilt and correlation to anterior acetabular coverage in the sagital plane. A cadaver study.
Lequesne's vertical-center-anterior margin (VCA) angle measured on the false profile view of the pelvis aims at quantifying the anterior acetabular coverage of the femoral head. The anterior delimitation of the acetabular roof is often defined on the false profile view but there are no data on its interrater reliability. Additionally, it is not known how pelvic tilt may influence this angle. Finally, the plane in which this angle is measured lies at an angle of 65 degrees to the sagittal plane and we wondered if this angle would be transposable to the anterior acetabular coverage measured in the sagittal plane. ⋯ Lequesne's VCA angle has an excellent interrater reliability and represents a reliable measure of acetabular dysplasia for comparisons with published data. Lequesne's VCA angle is influenced by pelvic tilt in a linear manner. Performing the false profile view in a standing position may reduce the clinical relevance of this dependency on pelvic tilt. The correlation of Lequesne's VCA angle to anterior acetabular coverage in the sagittal plane is low and therefore unsuitable to be transposed into the sagittal plane.

Closing lateral wedge valgus osteotomy with dynamic hip screw for the treatment of varus nonunion of pertrochanteric fracture: can restoration of biomechanics and stabilization alone heal?
Nonunion of pertrochanteric fracture is rare and its occurrence especially without prior surgical intervention has been hardly ever reported. Hence there is not much literature describing the best way to treat them. Nonunion of pertrochanteric fracture collapses in to varus by virtue of deforming action of muscles and thus deranging the biomechanics of the hip and indirectly preventing fracture union further. Hence it is very important to re-orient the abductor lever arm to biomechanically advantageous normal configuration favoring fracture healing. In general, principles of treatment of nonunion like open reduction of the fracture with freshening of fracture fragments, stabilization and bone grafting are very difficult to the surgeon and the patient. ⋯ All fractures and osteotomies had healed uneventfully at the last follow-up with good functional outcome. Harris Hip score had improved from 34 +/- 6 (range 22-47) to 89 +/- 4 (range 83-95) at an average of 11 months (range 7-13 months) follow-up. Valgus osteotomy converts shear forces across the fracture site into compressive forces thus achieving union.
