To use finite element analysis to study the stability of different fixation methods used to repair Vancouver type B1 periprosthetic fractures occurring after total hip arthroplasty (THA). ⋯ Better fixation power is achieved by using both proximal and distal screws (the locking-plate concept) in treating Vancouver type B1 periprosthetic fracture after THA.

Comparative Study
Neuroprotective effects of racemic ketamine and (S)-ketamine on spinal cord injury in rat.
The aim of this study was to investigate and to compare the potential neuroprotective effects of racemic ketamine, (S)-ketamine and methylprednisolone after an experimental spinal cord injury model in rats. ⋯ (S)-ketamine is more effective than methylprednisolone and racemic ketamine to reduce the LPO levels in subacute stage of spinal cord injury in rats. And, it is as effective as methylprednisolone in preventing secondary spinal cord injury histopathologically.

The operative workload at the surgical facility in Camp Bastion, Afghanistan, has previously been reported for the two-year period 1 May 2006 to 1 May 2008. There have since been considerable changes not only in the casualty rates, but also in the injury patterns encountered. Severe wounds from improvised explosive devices (IEDs) have become the signature injury of the insurgency. We present recent data for the surgical activity at the Joint Forces Medical Group Role 3 Hospital, Camp Bastion, for the two-year period 1 November 2008 to 1 November 2010. ⋯ The surgical workload at the Role 3 Hospital, Camp Bastion, Afghanistan is increasing. This is a result not only of increasing casualty numbers but also of increasingly severe injury patterns. With the growing use of powerful IEDs, traumatic lower limb amputations in particular are becoming more common, and are increasingly associated with significant pelvic and perineal injury. These complex injury patterns necessitate a multi-surgeon approach, and it is important these trends are noted for future planning of medical support to military operations in Afghanistan.
