The nature of military medical support necessarily changes in the transition from war fighting to the post-conflict phase. This paper examines the activity in the only British Military Hospital serving a multi-national divisional area in Iraq over 2004 during this post-conflict phase. Hand injuries were common and formed a large proportion of the workload seen at the military field hospital on operations. The overwhelming majority of hand trauma resulted in soft tissue injury. There was a clear predisposition to hand trauma for males, manual workers, combat soldiers and engineers/mechanics. While most hand injuries do not require surgical intervention, they impact on the effectiveness of the military population as a result of the large proportion of patients who are placed on restricted duties following hand trauma, 157 of 241 in this study, and the number of soldiers who require aeromedical evacuation for further treatment, 38 of 360 in this study. These injuries require that military surgeons and emergency physicians should be experienced in the initial management of hand trauma and hand trauma should be a core component of their training. The skills of the specialist hand surgeon may be required for definitive management of these injuries at a later stage.
