RESUMO
PURPOSE: Authors analyzed and compared the treatment result of distal chevron osteotomy between with and without adductor tenotomy. MATERIALS AND METHODS: 36 patients (60 feet) with a minimum follow-up of one year were involved in this retrospective study. The chevron osteotomy without adductor tenotomy was performed for 20 patients (30 feet) and chevron osteotomy with adductor tenotomy was done for 16 patients (30 feet). The first metatarsophalangeal (MTP) angle and angle between first and second metatarsal longitudinal axis (IM) was measured. The difference of these angles were measured pre-and postoperatively and compared using Student's T-test. RESULTS: In the group of chevron osteotomy with adductor tenotomy, the mean first MTP angle corrected 29 degrees pre-operatively to 9 degrees and the mean first IM angle corrected 16 degrees pre-operatively to 12 degrees. In the group of chevron osteotomy without adductor tenotomy the mean first MTP angle corrected 31 degrees pre-operatively to 11 degrees (P>0.05) and the mean first IM angle corrected 13 degrees pre-operatively to 11 degrees (P>0.05). Deep peroneal neuroma were found in 3 cases of chevron osteotomy with adductor tenotomy. CONCLUSIONS: Adductor tenotomy should be performed in selected patient with chevron osteotomy to prevent deep peroneal neuroma.
