A retrospective study of 50 chevron osteotomies evaluated subjective and objective functional and cosmetic results, which were in keeping with other reported studies - i.e. satisfactory subjective cosmesis in 98%; excellent or good pain relief in 84%; and satisfactory objective cosmesis in 84%. The correction of the 1st intermetatarsal angle averaged 3,3°, and that of the metatarsophalangeal valgus averaged 15°. Average active range of motion of the 1st metatarsophalangeal joint was 60°. Complications were generally mild and asymptomatic, and were usually iatrogenic. The findings of this study, together with information gained from a concomitant stress analysis, led to recommendations regarding operative technique.
