Application of nail-foot fixators in the treatment of chronic scapho-trapezio-trapezoid dislocation
摘要
Abstract
Objective To investigate the clinical efficacy of using nickel-titanium memory alloy three corner nail-foot fixators for scapho-trapezio-trapezoid(STT)arthrodesis in the treatment of chronic scapho-trapezio-trapezoid dislocation.Methods The retrospective study analyzed data of six patients diagnosed as chronic scapho-trapezio-trapezoid dislocation and treated at the 920th Hospital of the Joint Logistics Support Force of People's Liberation Army of China from January 2015 to January 2023.All six patients accepted STT arthrodesis with triangular nail-foot fixators made of nickel-titanium memory alloy.Clinical efficacy was assessed by the visual analogue scale(VAS),Cooney wrist scores(modified Green and O'Brien wrist scores or Mayo wrist scores),and the Patient-Rated Wrist Evaluation(PRWE)at pre-operative and the final follow-up.Results All patients accepted an effective follow-up of 14 to 60 months,with a mean follow-up of(27.83±17.62)months.No complications such as infection,failure of internal fixation and STT re-dislocation occurred in any of the patients,and the postoperative STT bone fusion rate was 100%.The results showed that the VAS scores(2.67±0.82)declined significantly at the final follow-up compared the preoperative value(5.33±1.03)(P<0.05).The average Cooney wrist score at the final follow-up was(83.33±4.68),which was significantly higher than that at pre-operation[(48.00±13.08)](P<0.05).The average PRWE score significantly dropped from(77.17±5.53)at pre-operation to(39.67±10.25)at the final follow-up(P<0.05).Conclusion The use of nickel-titanium memory alloy three corner nail-foot fixators for STT arthrodesis is effective in treating chronic scapho-trapezio-trapezoid dislocation.The procedure is simple,minimally invasive,and without significant complications,making it worthy of clinical application.关键词
