UNASSIGNED: A retrospective comparative study was conducted of patients who underwent either tibiotalocalcaneal arthrodesis or talar body prosthesis implantation between 2005 and 2012. The demographic matching process resulted in 24 patients per treatment group. Clinical outcomes were evaluated using a numeric rating scale (NRS) of 2 hours of activities of daily living (ADL) and Foot and Ankle Ability Measure (FAAM) for ADL. Radiographic assessments included the incidence of nonunion, adjacent joint arthritis, and prosthesis loosening. The 10-year survivorship of both surgical treatments was calculated. A P value of less than .05 was considered statistically significant.
UNASSIGNED: The median NRS of 2 hours of ADL and FAAM score for ADL were statistically significantly better in the talar body prosthesis group, with P values of .001 and <.001, respectively. The statistically significant differences in FAAM score for ADL exceeded the minimum clinically important difference. In the tibiotalocalcaneal arthrodesis group, nonunion was observed in 7 of 24 patients (29.2%). No prosthesis loosening was reported in the talar body prosthesis group. The 10-year survivorship was statistically significantly higher in talar body prosthesis than tibiotalocalcaneal arthrodesis (95.8% vs 70.8%), P = .023.
UNASSIGNED: Talar body prosthesis implantation in selected eligible patients demonstrated statistically significantly better 10- to 13-year clinical outcomes and higher 10-year survivorship compared with tibiotalocalcaneal arthrodesis in the surgical treatment of collapsed AVNT.
UNASSIGNED: Level III, retrospective cohort comparative study.
■对2005年至2012年期间接受胫骨关节固定术或距骨假体植入的患者进行了回顾性比较研究。人口统计学匹配过程导致每个治疗组24名患者。使用2小时日常生活活动(ADL)和ADL的足踝能力测量(FAAM)的数字评定量表(NRS)评估临床结果。影像学评估包括骨不连的发生率,相邻关节关节炎,和假体松动。计算了两种手术治疗的10年生存率。P值小于0.05被认为具有统计学意义。
■距骨假体组的ADL2小时的NRS中位数和ADL的FAAM评分在统计学上明显更好,P值分别为.001和<.001。ADL的FAAM评分的统计学显着差异超过了最小的临床重要差异。在胫骨关节固定术组中,24例患者中有7例(29.2%)出现骨不连.距骨假体组未见假体松动的报道。距骨假体的10年生存率在统计学上显着高于胫骨关节固定术(95.8%vs70.8%),P=.023。
■在选定的合格患者中,与胫骨关节固定术相比,在塌陷的AVNT的手术治疗中,在统计学上显示出10至13年的临床结局和更高的10年生存率。
■三级,回顾性队列比较研究。
