The Sponsel oblique fifth metatarsal osteotomy: evaluation with long-term follow-up

The results of an oblique fifth metatarsal osteotomy as described by Sponsel for the treatment of persistently symptomatic bunionette were reviewed in a long-term follow-up study. 63 operations performed in 41 patients over a 10-year span were followed for an average of 33 months. An overall 89% success rate of combined excellent and good results was achieved. Kirschner wire stabilization of the osteotomy improved the results. In those patients with poor results because of infection or recurrent symptoms, fifth metatarsal head resection was used as a salvage operation with satisfactory results.
