The Akin osteotomy without fixation in open hallux abducto-valgo correction surgery: A single center retrospective analysis of 286 cases

Between 2011 and 2018, 222 patients, 286 feet (147 left, 139 right) met the inclusion criteria. We found an average difference between pre-op and post-op at 3 months of distal articular set angle (DASA) of 7.0 degrees and average interphalangeal joint obliquity angle (IPOA) of 12.0 degrees (p < 0.001). All cases achieved fusion but in 5.9 % (17/289 cases) of cases, we observed delayed consolidation. The average union time in these cases was 22.1 weeks. Hyperextension of the distal fragment (mal union in plantar flexion) was observed in 7 cases (2.4 %). None of the 7 cases required correction. Out of 286 surgeries, 8 (2.7 %) required reoperation, but only one case for a hypocorrection required Akin's re osteotomy. Regarding the inter- and intra-observer correlations, good and excellent reliability are observed for all parameters under consideration. Conclusion The absence of internal fixation would appear not to impair osteotomy healing and complication rates compared with techniques with fixation would not appear to be worse. The results are encouraging; nevertheless, we believe that further studies need to be performed in order to confirm the data.
