Abstract:
Objective:To compare suture-button, absorbable screws (AS), and metal screws (MS) in the fixation of ankle fracture complicated with distal tibiofibular syndesmosis injury.Methods:A retrospective study was conducted to analyze the 71 patients with ankle fracture and distal tibiofibular syndesmosis injury who had been treated at Department of Foot and Ankle Surgery, Guangzhou Orthopedics Hospital from February 2020 to February 2023. There were 27 males and 44 females with an age of (49.6±10.3) years. The patients were assigned into 3 groups according to different treatment methods: a suture-button group in which 32 cases were treated with suture-button, an AS group in which 24 cases were treated with AS, and a MS group in which 15 cases were treated with MS to be removed at 8 to 12 weeks after operation. The 3 groups were compared in terms of intraoperative blood loss, operation time, and ankle range of motion, tibiofibular clear space (TFCS), and tibio-fibular overlap (TFOL) at the last follow-up, as well as American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores and visual analogue scale (VAS) pain scores at 3 months after operation and at the last follow-up.Results:There was no significant difference in the preoperative general data between the 3 groups, indicating comparability ( P>0.05). There were no significant differences in intraoperative blood loss, operation time, ankle range of motion, TFCS or TFOL between the 3 groups ( P>0.05). TFCS and TFOL at the last follow-up in all patients were significantly improved compared with those before operation ( P<0.05). The AOFAS ankle-hindfoot scores and VAS pain scores in the suture-button group and the AS group at 3 months after operation were significantly better than those in the MS group ( P<0.05). There was no significant difference in AOFAS ankle-hindfoot score or VAS pain score between the 3 groups at the last follow-up ( P>0.05). In all patients, the AOFAS ankle-hindfoot score and VAS pain score at the last follow-up were significantly better than those at 3 months after operation which were significantly better than those before operation ( P<0.05). Conclusions:In the fixation of ankle fracture complicated with distal tibiofibular syndesmosis injury, suture-button, AS and MS can all achieve definite clinical efficacy. As fixation with MS requires secondary surgical removal, its early functional score and pain score may be relatively poorer.
