title: A prospective comparison of clinical, radiographic, and intraoperative features of hallux rigidus: short-term follow-up and analysis.
abstract: Forty-seven patients (50 feet) underwent surgical intervention for symptomatic hallux rigidus between February 1998 and April 1999. Thirty-eight patients (41 feet) returned at 1 year for follow-up evaluation. Each foot was graded according to a four-stage hybrid radiographic grading system. At 1-year follow-up, 10 patients were classified as grade I, 17 as grade II, 12 as grade III, and 2 as grade IV. Subjective evaluation was based on a modified American Orthopaedic Foot and Ankle Surgery hallux metatarsophalangeal-interphalangeal 100-point scale. A pre- and postoperative objective physical examination and radiographic analysis were performed. Statistically significant differences between preoperative and postoperative values were found to exist for each portion of the subjective evaluation (p = .000); nonweightbearing dorsiflexion (p = .001); simulated weightbearing dorsiflexion (p = .003); metatarsal protrusion distance and angle of deviation of the second metatarsophalangeal joint (p = .000); and talar-first metatarsal angle (p = .015). For this specific patient population, the short-term results of surgical intervention for hallux rigidus provided subjective patient improvement and satisfaction, as well as a statistically significant but functionally minimal increase in first metatarsophalangeal joint dorsal range of motion. Additionally, in the 19 patients who underwent a periarticular decompression osteotomy, the intended correlation of plantar transposition of the capital fragment and offsetting the longitudinal shortening of the first metatarsal did not exist.
