The purpose of this study was to refine an accepted contaminated
rat femur defect model to result in an infection rate of approximately
50%. This threshold will allow examination of treatments aimed at
reducing infection in open fractures with less risk of type II error. Defects were created in the stablised femurs of anaethetised
rats, contaminated with Objectives

Hand injuries are common in military personnel deployed on Operations. We present an analysis of 6 years of isolated hand injuries from Afghanistan or Iraq. The AEROMED database was interrogated for all casualties with isolated hand injuries requiring repatriation between April 2003 and 2009. We excluded cases not returned to Royal Centre for Defence Medicine (RCDM). Of the 414 identified in the study period, 207 were not transferred to RCDM, 12 were incorrectly coded and 41 notes were unavailable. The remaining 154 notes were reviewed. 69% were from Iraq; only 14 % were battle injuries. 35% were crush injuries, 20% falls, 17% lacerations, 6% sport, 5% gun-shot wounds and 4% blast. Injuries sustained were closed fractures (43%), open fractures (10%), simple wounds (17%), closed soft tissue injuries (8%) tendon division (7%), nerve division (3%), nerve/tendon division (3%) complex hand injuries (4%). 112 (73%) of the casualties required surgery. Of these 44 (40%) had surgery only in RCDM, 32 (28%) were operated on only in deployed medical facilities and 36 (32%) required surgery before and after repatriation. All 4 isolated nerve injuries were repaired at RCDM; 2 of the 4 cases with tendon and nerve transection were repaired before repatriation. Of the 10 tendon repairs performed prior to repatriation 5 were subsequently revised at RCDM. This description of 6 years of isolated hand injuries in military personnel allows future planning to be focused on likely injuries and raises the issue of poor outcomes in tendon repairs performed on deployment.
