Abstract
Background: Arthroplasty or hemiarthroplasty for hallux rigidus of the first metatarsophalangeal (1 st MTPJ) is thought to lead to greater joint motion and improved gait function. There have been no studies to compare the effects of 1 st MTPJ arthrodesis and hemiarthroplasty on joint kinetics, kinematics and plantar pressures of foot and lower limb. Methods: A retrospective, case series pilot study approximately 22 months post operation. Subjects had either arthrodesis or a NorthStar HemiCAP hemiarthroplasty for osteoarthritis of the 1 st MTPJ. All had plantar pressure, kinetic and kinematic gait analysis as well as the Foot and Ankle Outcome Score (FAOS), and 1 st MTPJ range of motion (ROM). Results: For the hemiarthroplasty subjects the mean ROM on the non-operated 1 st MTPJ was 49 0 (SD23) but only19 0
