Abstract EN

Objective: To evaluate the outcome of modified Mitchell’s osteotomy for treatment of hallux valgus.

Methods: We reviewed the results of 69 patients (84 feet) in whom the modified Mitchell’s osteotomy with Y shape advancement of medial capsule, lateral adductor tenotomy and lateral capsule release, was done between 1993-2001 with an average follow up of 30 months (range 10-48 months).

Results: Radiographic and subjective results were evaluated.

Preoperative criteria included intermetatarsal angle of greater than 14 degrees (average 16.16), average metatarsophalangeal angle was 38.4 degrees (range 32-48 degrees) and painful Hallux valgus deformity.

The average postoperative intermetatarsal angle was 7.9 with relative correction of 8 degrees.

The average postoperative metatarsophalangeal angle was 9.2 degrees (range from 2-18).

Subjectively, all patients were satisfied with their results and stated they would have the procedure again.

There were no complications noted in the patients such as avascular necrosis, Hallux varus, and recurrence of deformity.

There were 6 delayed union cases for 6 months, and one infection.

Conclusion: The modified Mitchell’s osteotomy is an appropriate operative method that produces satisfactory results, and can be recommended in the treatment of moderate to severe Hallux valgus.
