Abstract

Purpose: We evaluated the short- to midterm outcomes of metatarsal head-resurfacing hemiarthroplasty and total metatarsophalangeal joint arthroplasty (total joint replacement [TJR]) as surgical treatments for advanced-stage hallux rigidus (HR).

Patients and methods: From 2012 to 2014, all data from patients who underwent surgery for the treatment of grades 2-3 HR were retrospectively reviewed, and 45 patients were included in this study. Of these patients, 26 underwent metatarsal head-resurfacing hemiarthroplasty (Group I) and 19 underwent TJR (Group II). All patients were clinically graded prior to surgery and at their final follow-up visits using the American Orthopedic Foot and Ankle Society's (AOFAS) hallux metatarsophalangeal-interphalangeal scale, a visual analog scale (VAS), and the "first metatarsophalangeal joint range of motion" (MTPJ ROM) score.

Results: Metatarsal head resurfacing was performed on 26 patients. Two patients underwent bilateral procedures, yielding a total of 28 cases in Group I. TJR was performed on 19 patients in Group II. Of the 26 Group I patients, 12 (46.2%) were male and 14 (53.8%) were female, with a mean age of 56.3±4.5 years (range: 47-63 years); the mean follow-up duration was 29.9±5.2 months. Of the 19 Group II patients, eight (42.1%) were male and eleven (57.9%) were female, with a mean age of 57.1±5.8 years (range: 45-66 years); the mean follow-up duration was 27.1±7.5 months. Significant improvements were evident in the AOFAS scores, and the VAS scores decreased, in both groups. No significant difference was evident between groups I and II.

Conclusion: After failure of conservative treatment in patients with moderate-to-severe HR, both MTPJ hemiarthroplasty and TJR were associated with effective recovery of toe function and MTPJ ROM, as well as good short- to midterm functional outcomes.
