[Analysis of results of treatment of hallux valgus by Dega osteotomy].

The evaluation included sixty eight feet (forty one patients) treated with Dega osteotomy for hallux valgus deformity. Patient's average age at the time of surgery was 47 years (ranging from 11 to 65). The average duration of follow-up was 4.5 years (ranging from 2 to 10). The clinical and X-ray examination found good results in 29% of cases, fair results in 59% and poor results in 12% of cases. Fair results were associated with persistent wide forefoot and shortening of first metatarsal bone. Poor results were associated with persistent valgus deformity of hallux, jatrogenic hallux varus (2 cases), shortening of first metatarsal bone amounting to more than 1.0 cm.
