Exchange nailing with enhanced distal fixation is effective for the treatment of infraisthmal femoral nonunions.
The treatment options for nonunions of infraisthmal femoral shaft fractures after internal fixation are controversial. Methods such as exchanging an existing nail with a nail of a larger size, dynamization, removal of the nail followed by plating, and bone grafting have all been reported. Among those options, exchange nailing seems to be the most popular choice. In this study, a Poller screw, or an additional interlocking screw, was used in conjunction with exchange intramedullary nailing. The purpose of this study was to evaluate the effectiveness of treating femoral shaft nonunions using insertion of a Poller screw or an additional interlocking screw in conjunction with intramedullary nail fixation. ⋯ Poller screws and additional interlocking screws, along with intramedullary nailing exchange, may be an effective and reliable alternative for treating infraisthmal femoral shaft nonunions.

Does tranexamic acid increase the risk of thromboembolism after bilateral simultaneous total knee arthroplasties in Asian Population?
To ascertain whether tranexamic acid reduces the blood loss and transfusion rate and volumes; increase the prevalence of deep vein thrombosis (DVT); and investigate factors associated with DVT in patients undergoing primary bilateral total knee arthroplasties (TKAs) without use of chemical thromboprophylaxis. ⋯ The use of tranexamic acid reduces the volume of blood transfusion and does not increase the prevalence of DVT or PE in the patients who did not receive routine chemical thromboprophylaxis after primary bilateral simultaneous sequential TKAs in Asian patients.

Safe zones and a technical guide for cerclage wiring of the femur: a computed topographic angiogram (CTA) study.
Cerclage wiring for reduction of complex femoral shaft fractures can create iatrogenic vascular injury. ⋯ Cerclage wiring should be started from the posterior intermuscular septum at the linea aspera. The safe area is the proximal half (midshaft) of the femur where the SFA and DFA lie at a safe distance from the femur. Between the midshaft and the distal 1/4, insertion of the passer must be done meticulously with the tip kept close to posteromedial cortex. Below the distal 1/4, the tip of the passer should be kept close to the posterior cortex to avoid injury to the SFA and the sciatic nerve.

The neurological outcome of radiotherapy versus surgery in patients with metastatic spinal cord compression presenting with myelopathy.
While radiotherapy is generally an acceptable treatment for metastatic spinal cord compression, surgical intervention is controversial due to the invasiveness and diversity of diseases in the patients being considered. The ideal treatment, therefore, depends on the situation, and the most acute treatment possible is necessary in patients presenting with myelopathy. We compared the neurological outcomes between radiotherapy and surgery in patients with metastatic spinal cord compression presenting with myelopathy. ⋯ Surgical decompression and stabilization may be required to improve the neurological function in patients with metastatic spinal cord compression presenting with myelopathy. However, the high rate of complications associated with surgery should be taken into consideration.

The impact of different peripheral suture techniques on the biomechanical stability in flexor tendon repair.
Flexor tendon repair consists of circumferential peripheral sutures in combination with core sutures to avoid fraying and reduces the exposure of suture material on tendon surface. The peripheral suture adds up to a tenfold increase of the biomechanical stability compared to the core suture alone. The purpose of our study was to determine the most favourable peripheral repair technique for tendon repair. ⋯ Beside the distance from tendon gap, the type of linkage of the suture material across and beneath the epitendineum is important for biomechanical stability. Simple-running suture is easy to use, even with a slight increase of the distance from tendon gap significantly increases biomechanical strength. For future repairs of flexor tendon injuries, 3 mm stitch length is highly recommended for simple peripheral suture, while the Halsted-mattress suture unites the most important qualities: biomechanically strong, most part of suture material placed epitendinous, and not too complicated to perform.
