A Comparison of the Effects of First Metatarsophalangeal Joint Arthrodesis and Hemiarthroplasty on Function of Foot Forces using Gait Analysis

摘要

Arthroplasty or hemiarthroplasty for hallux rigidus of the first metatarsophalangeal (I MTP.J) is thought to lead to greater joint motion and improved gait function. There have been no studies to compare the effects of I MTPJ arthrodesis and hemiarthroplasty on joint kinetics, kinematics and plantar pressures of foot and lower limb.
