Abstract
Purpose
Open reduction and internal fixation (ORIF) is the most commonly used surgical technique for talar neck fracture, but there are high risks for complications and poor functional outcomes. In this study, we reported the closed reduction and percutaneous internal fixation (CRPIF) technique of the bilateral approach of the Achilles tendon for simple displaced talar neck fracture, in comparison with ORIF.
Methods
Data of 15 patients in the CRPIF group and 22 in the ORIF group were included. The American Orthopaedic Foot and Ankle Society (AOFAS) score, Visual Analog Scale (VAS) score, 12-item Short-Form Survey (SF-12) score, range of motion (ROM), complications, and radiographic results were recorded and compared.
Results
The mean follow-up in the CRPIF group was 33.9 months. Complications included two cases of avascular necrosis (AVN) and two cases of osteoarthritis. All patients achieved bony union and recovered their pre-operative mobility. The mean follow-up in the ORIF group was 39 months. Complications included two cases of bony nonunion, nine AVN, and seven cases of osteoarthritis. Moreover, the mobility of the ORIF group was significantly lower than the CRPIF group post-operatively. The AOFAS score, VAS score, and SF-12 physical component score (PCS) for the CRPIF group were better improved than those for the ORIF group (ALL, P < 0.05).
Conclusions
The CRPIF technique of the bilateral approach of the Achilles tendon was an effective method for the treatment of simple displaced talar neck fractures. Compared with the ORIF, the limited blood supply of the talus was protected, provide better functional outcomes and biomechanical fixation, and lower incidence of resurgery and complication in the CRPIF.
