Abstract
This is a retrospective study examining the injury pattern, management and short-term outcomes of British Military casualties sustaining hindfoot fractures from the conflicts in Iraq and Afghanistan. In the 12-years of war, 114 patients sustained 134 hindfoot injuries. The calcaneus was fractured in 116 cases (87%): 54 (47%) were managed conservatively, with 30 (26%) undergoing internal fixation.
Eighteen-month follow-up was available for 92 patients (81%) and 114 hindfeet (85%). Nineteen patients (17%) required trans-tibial amputation in this time, with a further 17 (15%) requiring other revision surgery. Deep infection requiring surgical treatment occurred in 13 cases (11%) with S. aureus the commonest infective organism (46%). Deep infection was strongly associated with operative fracture management (p=0.0022). When controlling for multiple variables, the presence of deep infection was significantly associated with a requirement for amputation at 18 months (p=0.001). There was no association between open fractures and requirement for amputation at 18 months (p=0.926), nor was conservative management associated with amputation requirement (p=0.749).
