Results of hallux varus correction using an extensor hallucis brevis tenodesis

We have used an extensor hallucis brevis tenodesis procedure to treat symptomatic hallux varus in six patients (five women and one man). Indications for this procedure include the presence of flexible metatarsophalangeal and interphalangeal joints and the absence of arthritis. In this group (mean age, 47 years; range, 18-65 years), hallux varus followed correction of hallux valgus deformity in five patients and traumatic dislocation of the hallux in one patient. Excellent correction was noted and maintained in all patients at a mean interval of 28 months (range, 24-32 months) after surgery. Despite a slight decrease in dorsiflexion following surgery (average, 10 degrees), there were no additional complications noted, and the mean American Orthopaedic Foot and Ankle Society rating score improved from 61 to 85 after surgery.
