Cone arthrodesis of the first metatarsophalangeal joint.

The reliability and effectiveness of the treatment of hallux rigidus and symptomatic arthritis of the first metatarsophalangeal joint by the technique of cone arthrodesis are discussed. The authors reviewed the long-term results of cone arthrodesis in 51 patients with 60 operated feet. The average age was 55 years (range, 28 to 75 years) and the average length of follow-up was 39 months (range, 1 to 12 years). On questioning the patients regarding function, cosmesis, and pain, 41 of 51 patients were happy, eight of 51 patients were satisfied, and two of 51 were unhappy with their feet. No patient complained of persistent or recurrent hallux valgus deformity. Radiologically and clinically 58 of 60 first metatarsophalangeal joints were solidly fused. Two patients had a fibrous ankylosis which was functional and painless. Function with respect to gait and ability to walk on tiptoe and run was normal in all patients. In summary, the authors feel that this procedure is a reliable, effective treatment of painful arthritis of this joint.
