We evaluated the correlation between correction angle and pain of the first metatarsophalangeal joint in the treatment of hallux valgus.

The 28 cases (20 patients) with moderate to severe hallux valgus deformity and pain of the first metatarsophalangeal joint who underwent the distal soft tissue procedure and proximal metatarsal closing wedge osteotomy, were divided into two groups, Group I: no pain of the first metatarsophalangeal joint after surgery, and Group II: with persisting pain. We analyzed the correc-tion angle and pain of the first metatarsophalangeal joint in each group, preoperatively and at the last follow-up. All of the patients were women and their mean age was 58 years old. The average follow-up time was 18 months.

At the last follow-up, the 21 feet (75%) were free of pain of the first metatarsophalangeal joint. In 7 feet (25%) pain persisted. In group I, sufficient deformity correction was obtained, but in group II, the deformity was corrected insufficiently. A high correlation was observed between correction angle and pain relief.

A high correlation was obtained between correction angle and pain of the first metatarsophalangeal joint in the treatment of hallux valgus deformity. Therefore, in view of the patient's expectation of pain relief, meticulous attention should be paid to the correction of hallux valgus deformity.
