The interpositional arthroplasty procedure in treatment of degenerative arthritis of the second metatarsophalangeal joint.

A description of subjective and objective results in patients that received an interpositional arthroplasty procedure of the second metatarsophalangeal joint is presented. The authors evaluated nine patients using an observational, descriptive design. An independent examiner administered a subjective questionnaire at the same time a physical examination was performed. The average follow-up period was 35.5 months, with a range of 7 to 142 months. All patients showed an improvement in postoperative pain and activity. All but one of the patients rated their results as good or excellent. Additionally, the patient population demonstrated limited motion of the second metatarsophalangeal joint without pain or crepitus postoperatively. The subjective and objective results from this small case series were consistently good.
