Consideration of the femoral head cartilage thickness in preoperative planning in bipolar hemiarthroplasty.
Bipolar hemiarthroplasty (BH) is one of the commonly performed orthopedic procedures for the treatment of displaced fractures of the femoral neck. However, despite the common use of the BH, little has been written on preoperative planning for this operation. The purpose of this study was to assess the neglected subject which is about the cognition of the femoral head cartilage in planning a BH. ⋯ The femoral head cartilage should be considered when determining the level of femoral neck resection in order to reduce postoperative LLD when planning a bipolar hemiarthroplasty. Accurate and careful preoperative planning can result in balanced hip reconstruction by equalizing limb lengths and restoring the offsets.

Parecoxib has non-significant long-term effects on bone healing in rats when administered for a short period after fracture.
Selective and non-selective cyclo-oxygenase (COX) inhibitors impair bone healing by inhibiting prostaglandin synthesis. The purpose of this study was to evaluate the long-term effect of parecoxib, a selective COX-2 inhibitor, on bone healing in rats, when it is applied in a pattern similar to clinical treatment patterns, that is, in a high dose and for a short period after bone fracture. ⋯ Parecoxib does not have a significant long-term effect on bone healing in rats, when it is administered in a high dose and for a short period after bone fracture.

Comparative StudyA new distractable implant for vertebral body replacement: biomechanical testing of four implants for the thoracolumbar spine.
Expandable titanium implants for vertebral body replacement in the thoracolumbar spine have been well established in the reconstruction of the anterior spinal column. Load transfer at the bone-implant interface remains a point of concern. The purpose of the study was to compare the performance in axial load transfer from the implant to the vertebral body in four different implants, all of them in clinical use to date. ⋯ The modified end plate design of Synex II was found to perform comparably at least with regard to the compressive performance at the implant-bone interface. The risk of the new implant for collapse into the vertebral body might be reduced when compared to the competitors.

Comparative StudyComparison of kyphoplasty and vertebroplasty in the treatment of fresh vertebral compression fractures.
As life expectancy in the population rises, osteoporotic fractures are seen most frequently in the proximal femur and the vertebral column. In balloon kyphoplasty and vertebroplasty, we have two minimally invasive treatment procedures available. Although they have both been controversially discussed in studies, they have seldom been directly compared. ⋯ The two surgical procedures were both followed by significant pain relief, and the quality of life was similar regardless of the procedure used. Balloon kyphoplasty led to an ongoing reduction of freshly fractured vertebrae and was followed by a lower rate of cement leakage.

Case ReportsNew technique for knee flexion contracture with patella infera using patellar tendon reconstruction combined with anterior capsular shift: a case report.
A 24-year-old male presented with an open fracture of the left patella (Gustilo-Anderson grade III-A) and fracture of the left femoral lateral condyle, and subsequent patella alta suggesting rupture of the left patellar tendon. This initial injury was treated 6 months earlier in another hospital. He was referred because of limited knee motion and radiographs showed severe patella infera. By means of a combination of a contralateral BTB graft and soft tissue repair named anterior capsular shift, the knee contracture with patella infera was resolved successfully.
