Management of soft tissue deficiency of the hallux: salvage in trauma, diabetes, and following surgical complications.
Loss of the hallux can lead to significant gait problems and cause difficult biomechanical problems with weight bearing. Amputation of the first ray should be avoided when possible. Soft tissue defect of the hallux can be particularly difficult to manage because of the absence of local muscle tissue for coverage. In younger patients, soft tissue loss usually is related to trauma; an understanding of the techniques that are available for coverage are important to maintain length and function of the first ray. Diabetic neuropathy and resultant ulceration of the hallux or metatarsophalangeal joint is another common cause of soft tissue deficiency that may lead to deep infection and potentially result in amputation. Certain systemic problems, such as inflammatory diseases or gout, can cause significant degeneration of the local tissues which also can be problematic. Wound dehiscence or loss of skin flaps that are created during surgery represent further difficulties that may be encountered. This article reviews the common causes of amputation of the hallux and the principles that are necessary for salvage of the digit.
