Abstract

Background: The Akin osteotomy is widely used to correct the hallux valgus and different fixation techniques have been proposed. Currently most of these procedures coexist, with disagreement on which offers the best results. The aim of this study is to compare the radiological outcome of the original Akin's technique with one in which a staple was used to stabilize the osteotomy. We also assessed whether other factors unrelated to the osteosynthesis could influence the radiological outcome. Methods: We retrospectively reviewed data from 118 patients who underwent a scarf and Akin osteotomy. In 60 patients the Akin osteotomy was fixed with a staple and in 58 cases no staple was used. Hallux valgus angle (HVA), distal articular set angle (DASA), interphalangeal angle (IPA) and tibial sesamoid position were measured. The presence of lateral cortex disruption of the phalanx was also included in the analysis. Results: Six variables significantly influenced the radiological results of the Akin osteotomy: preoperative HVA, IPA and tibial sesamoid position, laterality, postoperative cortical disruption and use of a staple. Conclusion: Ours results suggest that the original Akin's technique seems to offer equal or better results than a variation in which a staple is added to stabilize the osteotomy.
