Weil osteotomy for metatarsalgia of lesser toes with hallux valgus

Introduction: Painful plantar callosities under the second and third metatarsal heads are not uncommonly associated with hallux valgus and there have been controversies concerning its treatment modalities. We performed the Weil osteotomy in patients with painful callosities under the second and third metatarsal head associated with hallux valgus, and evaluated the outcome clinically & radiologically. Materials and Methods: From November 2000 through November 2001, out of 51 patients diagnosed with hallux valgus, the Weil osteotomy was performed in 5 women associated with painful callosities under the second and third metatarsal heads. The mean age was 53.4 years (range, 31-66) with a minimum follow-up period of 12 months(range, 12-16). Results: The mean AOFAS lessor metatarso-phalangeal-interphalngeal Scale(LMIS) improved from 61.2 points preoperatively to 88.8 points postopertively. Mean decreases in length of the second and third metatarsal after surgery were 3.2mm and 3mm. Conclusion: We experienced improvement of metatarsalgia in 80% of patients by Weil osteotomy and all patients were symptom-free at last follow-up, suggesting that the Weil osteotomy is an effective procedure in treating painful plantar callosities under the second and third metatarsal heads associated with hallux valgus.
