Progress report of the minimally invasive technique for Achilles tendon lengthening for a patient with critical limb ischemia

Abstract

Patients with critical limb ischemia（CLI）for whom the minimally invasive technique was used for tendon Achilles lengthening（MIT-TAL）were examined. They had a limited dorsiflexion range of motion and risk of ulcer development. In total, seven patients（five males, two females）underwent MIT-TAL. Plantar forefoot ulceration, dorsiflexion range of motion, plantar pressure, ankle flexion muscle power and walking ability were measured before and after MIT-TAL. All subjects that were investigated had no plantar forefoot ulcers, and an improved dorsiflexion range of motion and plantar pressure. Ankle flexion muscle power was improved to the level before MIT-TAL. Walking ability remained unchanged. MIT-TAL is effective for patients with CLI to prevent ulcers, and improve their physical function and walking ability.
