The modified distal horizontal metatarsal osteotomy for correction of bunionette deformity.
BACKGROUND
Bunionette is a common deformity for which a number of operative procedures have been described. The objective of this study was to evaluate the results of a modified distal horizontal metatarsal osteotomy in the correction of symptomatic bunionette.


METHODS
Metatarsal osteotomies were done in 21 feet in 14 patients (11 females, three males) with an average age of 44 (range 20 to 67) years at the time of operation. The average followup was 32 (range 12 to 52) months.


RESULTS
The average Lesser Toe Metatarsophalangeal-Interphalangeal Score of the American Orthopaedic Foot and Ankle Society increased from 42 points (range 24 to 50) preoperatively to 87 points (range 60 to 100) at the last followup. The fifth metatarsophalangeal angle averaged 18 degrees (5 to 38 degrees) preoperatively and 5 degrees (-5 to 26 degrees) at final followup. The 4-5 intermetatarsal angle averaged 14 degrees (10 to 20 degrees) preoperatively and 9 degrees (5 to 12 degrees) at final followup. Hardware was removed from two feet and scheduled for a third foot because of symptomatic skin irritation.


CONCLUSIONS
The modified distal horizontal metatarsal osteotomy is a stable and reliable method for correction of bunionette. Unsatisfactory results in our patients were related to prominent hardware.
