The objective of this study is to establish the relative strength of fixation of a locking distal femoral plate compared with the condylar blade plate. ⋯ The locking screw-plate construct proved stronger than the blade plate in both cyclic loading and ultimate strength in biomechanical testing of a simulated A3 distal femur fracture. Although differences were small, the biomechanical performance of the locking plate construct over the blade plate may lend credence to use of the locking plate versus the blade plate in the fixation of comminuted distal femur fractures.

To evaluate the utility of negative-pressure wound therapy (NPWT) in the setting of high-energy open tibial shaft fractures. DESIGN, SETTING, AND PATIENTS/PARTICIPANTS: This was a retrospective consecutive series in a level 1 university-based trauma center. Forty-nine consecutive patients presenting to a level 1 trauma center between 1996 and 2004 with 50 grade/type III open tibial shaft fractures were assessed. ⋯ Infection and nonunion rates with the use of NPWT for temporary coverage of wounds associated with grade/type III open tibial shaft fractures are similar to those of historical controls, but this technique may be beneficial in decreasing the need for free tissue transfer or rotational muscle flap coverage.

Meta Analysis
Complex limb salvage or early amputation for severe lower-limb injury: a meta-analysis of observational studies.
Leg threatening injuries present patients and clinicians with a difficult decision: whether to pursue primary amputation or limb salvage? The purpose of our study was to review the literature in an effort to inform this management decision. ⋯ Functional outcome among patients who present with leg-threatening injuries are not significantly different, at least up to 7 years, whether they are managed with limb salvage or primary amputation. Research to optimize triage decisions to avoid failed limb salvage as well as on interventions targeting important psychosocial prognostic variables should be considered a priority.

Randomized Controlled Trial
Prolonged thromboprophylaxis with dalteparin after surgical treatment of achilles tendon rupture: a randomized, placebo-controlled study.
Prophylaxis against thromboembolic complications has become routine after major orthopedic surgery. In contrast, it remains an issue for debate whether prophylaxis after minor surgery and immobilization is necessary, even though these treatments are well-known risk factors for deep-vein thrombosis (DVT). The objective of this study was to evaluate the efficacy of dalteparin during lower-limb immobilization after surgical treatment of Achilles tendon rupture. DESIGN SETTING, AND PATIENTS: Randomized, placebo-controlled, double-blind study of 105 consecutive patients surgically treated for Achilles tendon rupture in a trauma hospital. DVT screening with color duplex sonography was conducted 3 weeks and 6 weeks after surgery. All DVTs were confirmed with phlebography. Intervention was placebo or dalteparin (5000 U) given subcutaneously once daily for 6 weeks postoperatively. ⋯ DVT is common after surgical treatment of Achilles tendon rupture, and therefore effective thromboprophylaxis is desirable. In our study, thromboprophylaxis with dalteparin, however, does not affect the incidence of DVT during immobilization after Achilles tendon rupture surgery. Long-term effects of immobilization, such as the risk for postthrombotic syndrome, need to be investigated further.
