Abstract

PROPOSE: This study was retrospectively to review the surgical results for moderate to severe hallux valgus corrected with a modified McBride procedure and proximal metatarsal crescentic osteotomy.
MATERIALS AND METHODS
Between August 1997 and August 2001, 15 patients with 22 bunion underwent surgical correction and were followed for an average 29.3 months (range, 18 to 53 months). Clinical results were evaluated with AOFAS clinical rating system for hallux and radiological measurements were done preoperatively and at a minimum of 12 months postoperatively.
RESULTS
The average AOFAS clinical rating score improved from 47.5 to 86.0. Union of the osteotomy site occurred at 9.5 weeks except one delayed union. The hallux valgus angle improved an from 36.5 degrees to 15.7 degrees and the intermetatarsal angle improved from 17.4 degrees to 8.6 degrees on average. Dorsiflexion of the first metatarsal at the osteotomy site was present in three (13.6%) with average 4 degrees. Complications were two recurred deformity, one hallux varus and one painful transfer lesion. There was a high level of satisfaction with clinical results in 11 patients (73.3%) with 17 feets and cosmesis in 18 feets (81.8%).
CONCLUSION
Modified McBride procedure and proximal metatarsal crescentic osteotomy based on careful patient selection and meticulous technique showed satisfactory outcome for moderate to severe hallux valgus.
