Syndesmotic disruption occurs in 20% of ankle fractures and requires anatomical reduction and stabilization to maximize outcomes. Although screw breakage is often asymptomatic, the breakage location can be unpredictable and result in painful bony erosion. The purpose of this investigation is to report early clinical and radiographic outcomes of patients who underwent syndesmotic fixation using a novel metal screw designed with a controlled break point. We performed a retrospective review of all patients who underwent syndesmotic fixation utilizing the R3lease Tissue Stabilization System (Paragon 28, Denver, CO) over a 12-month period. Demographic and screw-specific data were obtained. Postoperative radiographs were reviewed, and radiographic parameters were measured. Screw loosening or breakage was documented. 18 patients (24 screws) met inclusion criteria. The mean follow-up was 11.7 months (range = 6.0-14.7 months). 5/24 screws (21%) fractured at the break point. No screw fractured at another location, nor did any fracture prior to resumption of weight bearing; 19 screws did not fracture, with 8/19 intact screws (42.1%) demonstrating loosening. There was no evidence of syndesmotic diastasis or mortise malalignment on final follow-up. No screws required removal during the study period. This study provides the first clinical data on a novel screw introduced specifically for syndesmotic fixation. At short-term follow up, there were no complications and the R3lease screw provided adequate fixation to allow healing and prevent diastasis. Although initial results are favorable, longer-term follow-up with data on cost comparisons and rates of hardware removal are needed to determine cost-effectiveness relative to similar implants.: Level IV: Retrospective case series.
下胫腓联合损伤发生于20%的踝关节骨折中,需要进行解剖复位和固定以实现最佳治疗效果。尽管螺钉断裂通常无症状,但断裂位置可能不可预测,并导致疼痛性骨质侵蚀。本研究的目的是报告使用一种设计有可控断点的新型金属螺钉进行下胫腓联合固定的患者的早期临床和影像学结果。我们对在12个月期间接受使用R3lease组织稳定系统(Paragon 28,丹佛,科罗拉多州)进行下胫腓联合固定的所有患者进行了回顾性研究。获取了人口统计学和螺钉特定数据。复查术后X线片并测量影像学参数。记录螺钉松动或断裂情况。18例患者(24枚螺钉)符合纳入标准。平均随访时间为11.7个月(范围=6.0 - 14.7个月)。24枚螺钉中有5枚(21%)在断点处断裂。没有螺钉在其他位置断裂,也没有在恢复负重前发生骨折;19枚螺钉未断裂,其中19枚完整螺钉中有8枚(42.1%)出现松动。末次随访时没有下胫腓联合分离或关节间隙不齐的证据。在研究期间没有螺钉需要取出。本研究提供了关于一种专门为下胫腓联合固定引入的新型螺钉的首批临床数据。在短期随访中,没有并发症,R3lease螺钉提供了足够的固定以促进愈合并防止分离。尽管初步结果良好,但需要进行更长时间的随访,并提供成本比较和内固定取出率的数据,以确定相对于类似植入物的成本效益。:IV级:回顾性病例系列。
