经外踝截骨入路行PHILOS 板内固定在踝关节融合术中的应用
曹乐,苗旭东 (浙江大学医学院附属第二医院骨科,杭州 310009)
[摘要] 目的 分析经外踝截骨入路行PHILOS 板内固定在踝关节融合中的手术方法和临床疗效。方法 选取2010年1月至2013年12月收治的严重踝关节炎患者82例,其中男52例,女30例,平均年龄51岁(35 ~ 70岁);左踝34例,右踝48例;合并踝关节内翻15例,外翻8例。应用美国足与踝关节协会(AOFAS)踝与后足评分和视觉模拟评分法(VAS)对术前、术后情况进行评价。结果 79例患者获得随访,随访率为96.3%。随访时间9 ~ 48个月,平均24.2个月。随访患者经X 线片和CT 检查证实均获得骨性融合,无畸形愈合、融合失败等并发症发生,AOFAS 踝与后足评分由术前的(64.2±5.3)分提升为术后的(88.1±6.1)分,VAS 评分由术前平均(6.0±0.5)分降至术后(1.0±0.2)分,术前术后差异均有统计学意义(P 均<0.05)。结论 采用经外踝截骨入路PHILOS 板内固定行踝关节融合,手术操作简便,固定强度可靠,融合率高,具有良好的临床疗效。

[Abstract ] Objective To evaluate the surgical technique of lateral malleolus osteotomy and internal fixation with Proximal Humerus Internal Locking System (PHILOS) in ankle arthrodesis and its clinical effect. Methods Choose between January 2010 and December 2010 treated 82 cases of patients with severe ankle arthritis . Of the patients, 52 were males and 30 females, aged 35~70, on average 51; 34 left ankles and 48 right ankles; 15 accompanied with ankle varus deformity and 8 with valgus deformity. The AOFAS ankle and hindfoot score system and VAS score were used to evaluate and analyze the preoperative and postoperative status. Results The 79 patients (96.3%) were followed up. The follow-up was 9~48 months, on average 24.2 months. All followed-up patients showed bone fusion without complication of nonunion and malunion. The postoperative AOFAS score was (88.1± 6.1), showing significant difference when compared with the preoperative score, which was (64.2± 5.3). The VAS score decreased from preoperative (6±0.5) to postoperative (1±0.2) with a significant difference in statistics(all P <0.05). Conclusions The lateral malleolus osteotomy and internal fixation with proximal humerus internal locking system has the advantages of relatively simple technique, strong fixation, high fusion rate, and reliable clinical effect.

踝关节炎有多种原因,包括原发性骨关节炎、
创伤、神经性关节病、感染、缺血性坏死、炎性关节炎和手术失败。踝-足支具作为踝关节炎的非手术疗法仅能缓解症状,但无法阻止或减缓疾病发展[1]。踝关节融合术是用来治疗经非手术治疗无效的终末期踝关节疾病的有效方法,虽然在国外踝关节置换术日益流行,踝关节融合仍是
终末期踝关节炎的一种有效治疗手段,尤其是在国内。踝关节融合术的目标是获得稳定的、跖行的、无痛的踝关节。经文献报道,已有40多种可供选择的踝关节融合手术技术,各有其优劣[2-6]。该研究选取2010年1月至2013年12月采用经外踝截骨入路用肱骨近端内固定锁定系统(proximal humerus internal locking system,PHILOS)(Synthes 公司,瑞士)行踝关节融合术治疗的82例严重踝关节炎患者,并进行了中期随访,效果满意,现报道如下。
