Management of Soft Tissue Deficiency of the Hallux: Salvage in Trauma, Diabetes, and Following Surgical Complications

摘要: The hallux is important functionally and biomechanically in maintaining normal function of the foot. Loss results decreased push-off strength may result significant balance problems diabetic nondiabetic patients. bears approximately 22% body weight during [1]. digit accompanied by force transfer to middle column foot which cause symptoms sensate neuropathic Both experience lesions. In patient, this lead intractable pain, recurrent calluses, stress fractures. insensate loss ulceration beneath remaining metatarsal heads, possible fracture dislocation through midfoot as a abnormal weight-bearing (Fig. 1). defect that caused amputation leaves toes subject varus angulation; further functional deformity. cases necessary, attempts should be made salvage base proximal phalanx sesamoid complex preserve insertion flexor hallucis brevis muscle integrity plantar fascia for support longitudinal arch, act buttress deformity lesser digits.
