Intraoperative labral injury during the establishment of the first portal in hip arthroscopy has been reported to be as high as 20%.
The purpose of the study was to prospectively identify the incidence of acetabular labral injuries that occurred while using a current technique for the establishment of portals during hip arthroscopy.
Case series; Level of evidence, 4.
Between the years 2008 and 2010, data were prospectively collected for all patients undergoing hip arthroscopic surgery. Patients with previous labral resection or Tonnis grade greater than 1 were excluded. Patients were positioned supine, traction was applied, and portals were established. The anterolateral portal was created first by venting the joint with a spinal needle and then re-entering the joint with the same needle with the bevel side facing the labrum. Next, the midanterior portal was created under vision. A thorough examination of the acetabular labrum was conducted arthroscopically through multiple viewing portals, and labral injuries related to the establishment of portals were identified and noted.
A total of 300 patients were included in the study; only 2 patients (0.67%) suffered intraoperative labral injuries at the study period. One injury occurred during revision arthroscopy, while the second involved a hyperplastic labrum in a dysplastic hip. No patient with normal hip morphological characteristics undergoing a hip arthroscopy suffered a labral tear as a result of portal placement.
The incidence of iatrogenic labral injury during hip arthroscopy can be as low as 0.67% when using the described technique.
髋关节镜检查中建立第一入口时发生的术中盂唇损伤的发生率高达 20%。
本研究的目的是前瞻性地确定在髋关节镜检查中使用当前技术建立入口时发生的髋臼唇损伤的发生率。
病例系列；证据水平，4 级。
在 2008 年至 2010 年间，前瞻性地收集了所有接受髋关节镜手术的患者的数据。排除了先前有盂唇切除术或 Tonnis 分级大于 1 的患者。患者仰卧位，施加牵引，并建立入口。首先通过脊柱针排空关节来创建前外侧入口，然后用同一根针重新进入关节，斜面朝向盂唇。接下来，在直视下创建中前入口。通过多个观察入口进行彻底的髋臼唇检查，并识别和记录与建立入口相关的盂唇损伤。
共有 300 例患者纳入研究；仅在研究期间有 2 例（0.67%）患者发生术中盂唇损伤。1 例发生在翻修关节镜检查时，另 1 例发生在发育不良髋关节中增生的盂唇。在形态特征正常的髋关节接受髋关节镜检查的患者中，没有因入口放置而导致盂唇撕裂。
当使用描述的技术时，髋关节镜检查中医源性盂唇损伤的发生率可低至 0.67%。
