Biomechanics of the Diabetic Foot: Consideration in Limb Salvage.

SIGNIFICANCE: The biomechanics of the diabetic foot is altered and maladaptive. We lack a thorough understanding of the functional consequences of limb salvage. We currently rely on observation and descriptive data pertaining to the biomechanics of the diabetic foot. RECENT ADVANCES: Technology has driven our ability to objectively describe biomechanics of the diabetic foot. Dynamic, segmental, gait analysis in conjunction with peak plantar pressure measurements have provided valuable insight. CRITICAL ISSUES: The biomechanical pathogenesis of a chronic ulceration that necessitates limb salvage is difficult to capture. The subsequent changes that occur after limb salvage are even more difficult to understand. However, methodical biomechanical analysis over the past several decades have provided a deeper understanding of diabetic foot function. FUTURE DIRECTIONS: Ultimately, a better understanding of the biomechanics of the diabetic foot would allow us to better select the most appropriate amputation level and maximize function after limb salvage attempt.
