Comparative Study
A mechanical comparison of the locking compression plate (LCP) and the low contact-dynamic compression plate (DCP) in an osteoporotic bone model.
To determine if locking compression plates (LCP) are mechanically advantageous compared to low-contact dynamic compression plates (DCP) when used as a bridging plate in a synthetic model of osteoporotic bone. ⋯ In a synthetic model, the LCP was mechanically superior to the DCP when used as a bridging plate and tested in axial compression.

Detection of tibial fractures in which a concomitant ankle injury may exist. ⋯ Due to the obvious injury of the tibia, the potential instability of the ankle joint is often overlooked, and the risk of development of secondary osteoarthritis is often consequently underestimated. Added attention should be paid to the ankle in the following tibial fracture cases: pronation-eversion trauma, spiral fracture of the tibia, proximal fibular fracture, or intact fibula. Using these markers, we were able to diagnose 20.1% of combined injuries compared to our retrospective study in 1999, in which only 13.6% of these injuries could be detected (Pearson r=0.1305, not significant).

Displaced and unstable fractures of the proximal humerus are notoriously difficult to manage. Successful surgical treatment requires finding the appropriate balance between adequate exposure for reduction and rigid fixation and minimizing soft tissue dissection. The anterolateral acromial approach was developed to allow less invasive treatment of proximal humerus fractures. ⋯ Twenty-three patients were evaluated clinically at a minimum follow-up of 1 year (average, 28 months) by clinical examination for range of motion and nerve function and a QuickDASH score. There were no axillary nerve deficits postoperatively related to the approach, and the average QuickDASH score was 25.2 (0, best; 100, worst). This approach allowed direct access to the lateral fracture planes for fracture reduction and plate placement or safe nail and interlocking screw placement.

The objective of this study was to compare the effect of tourniquet-induced ischemia/reperfusion (I/R) injury on the recovery of muscle function with and without prior hemorrhage. ⋯ The functional loss resulting from tourniquet application is exacerbated by the superimposition of hemorrhage in the predominantly fast-twitch plantaris but not the predominantly slow-twitch soleus. This was likely a result of metabolic derangement resulting from the combination of hemorrhage and tourniquet application. The development of interventions designed to attenuate the loss of muscle mass and function following complex trauma is necessary for optimal patient recovery.
