Title: Minimally invasive Akin osteotomy and lateral release: Anatomical structures at risk—A cadaveric study
Author: Yañez Arauz, Juan.; Del Vecchio, Jorge.; Codesido, Mariano.; Raimondi, Nicolás.
Abstract: BACKGROUND: Among the many surgical techniques used for hallux valgus correction, different osteotomies may be performed in the proximal phalanx as well as lateral release as associated procedures. The aim of this study is to analyze the anatomical relationships and the risks for the soft tissue lessions when performing the dorsomedial minimally invasive surgery (MIS) portal for the Akin osteotomy, and the MIS dorsolateral portal for lateral release, in order to define a safety zone when conducting the procedure in order to avoid complications. MATERIALS AND METHODS: The procedures were carried out on 16 fresh-frozen cadaveric feet. A MIS dorsomedial and dorsolateral portals were performed. The anatomical dissection of the cadaveric pieces was carried out and the different anatomic and surgical relationships were analyzed and measured. RESULTS: No nerve injury was found. Injury of the extensor hallucis longus (EHL) paratendon were seen in 9 cases (56%). There was no injury of the flexor hallucis longus (FHL) tendon and or collateral plantar nerves. A partial injury of the FHL sheath was observed in 44% of the samples. CONCLUSIONS: Although percutaneous Akin osteotomy is clinically effective, the possibility of injury of anatomic structures is high (9-55%), however injuries upon vascular or nerve structures were not seen.
