Over a 20 year period, five patients experienced serious vascular complications involving major arterial insult during various routine orthopaedic procedures. The nature of the vascular damage necessitated immediate surgical repair which was performed successfully by an orthopaedic microsurgeon who was either a member of the initial surgical team or the hospital's Orthopaedic Unit. The purpose of this study is to illustrate not only the severity of these limb and/or life-threatening complications, but also to focus attention on the importance of the orthopaedic surgeon's ability to manage these serious injuries promptly. This suggests the need for Orthopaedic Units to have surgeons with adequate training in microvascular techniques, so as to be able to successfully manage these unexpected and serious complications. We conclude that the presence of a vascular surgeon or an orthopaedic surgeon trained in microvascular surgery represents an invaluable attribute to the orthopaedic team, and minimizes, if not eliminates the potentially disastrous outcome from these serious intraoperative vascular complications.
