摘要:

背景:跟骨骨折是最常见的跗骨骨折,约75%跟骨骨折呈现为移位的关节内骨折,如何处理此类跟骨关节内骨折,目前学术界仍存在争议。
目的:观察关节镜辅助下经皮微创螺钉置入内固定修复Sander Ⅱ型跟骨骨折的解剖形态及临床效果。
方法:2009年5月至2012年5月采用关节镜辅助下经皮微创螺钉置入内固定修复Sander Ⅱ型跟骨骨折患者61例(61足)。所有患者要求治疗后3周、6周、12周、1年、以后每年来院进行临床和影像学评估1次。采用美国足踝外科学会评定踝关节功能结果;同时记录有无皮肤坏死、切口感染等并发症;通过X射线片评估Bohler角、Gissane角、跟骨高度及跟骨宽度。
结果与结论:61例患者均获得随访,随访时间24-60个月,无皮肤坏死、血肿,无切口愈合问题以及深部感染等并发症。住院天数6-25 d,平均(12.7±6.9) d。至末次随访时,美国足踝外科学会评分为88-100分,平均(93.6±3.1)分,优良率100%;患者治疗后恢复工作时间为8-14周,平均(10.7±2.9)周。所有患者踝关节或距下关节活动度受限小于10°。修复术后即刻X射线片检查,显示关节面解剖复位56例(92%),非解剖复位5例(8%)。末次随访时,Bohler角为23°-30°,平均(28.4±4.9)°;Gissane角112°-124°,平均(119.9±7.8)°;跟骨高度39-45 mm,平均(43.4±4.2) mm;跟骨宽度27-32 mm,平均(30.4±2.5) mm;骨折愈合时间12-20周,平均(16.7±4.2)周。末次随访时患者治疗后Bohler角、Gissane角、跟骨高度及跟骨宽度均较治疗前有明显的改善(P < 0.05)。提示关节镜辅助下经皮微创螺钉置入内固定修复Sander Ⅱ型跟骨骨折,可以恢复跟骨解剖形态,取得满意的临床功能,而无切口愈合不良、感染等并发症发生。

Abstract:

BACKGROUND: The calcaneal fracture is the most common tarsal bone fracture. Approximately 75% calcaneal fractures presented as the displaced intraarticular fractures. How to treat intraarticular calcaneal fractures remains controversial.
OBJECTIVE: To observe the anatomy and clinical effect of minimally invasive percutaneous screw fixation in repair of Sander II calcaneal fractures under the arthroscope. 
METHODS: From May 2009 to May 2012, 61 patients (61 feet) with Sander II calcaneal fractures were repaired by minimally invasive percutaneous screw fixation under the arthroscope. All patients received clinical and imaging evaluation at 3, 6, 21 weeks, and 1 year after treatment. From then on, the evaluation was performed every year. American Orthopaedic Foot and Ankle Society ankle hindfoot score was used to assess ankle joint function. Simultaneously, complications such as skin necrosis and wound infection were recorded. Radiographic outcomes were assessed by Bohler angle, Gissane angle, calcaneal height and width.
RESULTS AND CONCLUSION: A total of 61 patients were followed up for 24 to 60 months. No complications were seen such as wound healing or deep infection. The time of hospitalization was 6-25 days, averagely (12.7±6.9) days. At the final follow-up, American Orthopaedic Foot and Ankle Society ankle hindfoot score was 88-100, averagely (93.6±3.1), with an excellent and good rate of 100%. The time of return to work after treatment was 8-14 weeks, averagely (10.7±2.9) weeks. Range of motion of ankle or subtalar joint of all patients was limited less than 10°. Immediate postoperative X-ray showed that anatomic reduction of the articular surface was detected in 56 patients (92%), and non-anatomic reduction was found in 5 patients (8%). At last follow-up, the mean Bohler angle was (28.4±4.9)° (range, 23°-30°); the mean Gissane angle was (119.9±7.8)° (range, 112°-124°); the mean calcaneal height was (43.4±4.2) mm (range, 39-45 mm); the mean calcaneal width was (30.4±2.5) mm (range, 27-32 mm); the average fracture healing time was (16.7±4.2) weeks (range, 12-20 weeks). Bohler angle, Gissane angle, calcaneal height, and calcaneal width at last follow-up were significantly improved compared with pretreatment (P < 0.05). These findings suggest that under the arthroscope, minimally invasive percutaneous screw fixation for Sander II calcaneal fractures can restore calcaneal anatomy, achieve a satisfactory clinical function, without complications such as poor woundhealing or infection.
