To document the effect of iatrogenic labral punctures (ILPs) on the clinical results of hip arthroscopy.
From a database of 250 consecutive patients who had their hip arthroscopy performed by the senior author, 50 patients with ILPs were identified. Results of hip arthroscopy in these patients were compared with those of a matched group of 50 patients who did not have labral puncture (NLP). All hips were assessed with Byrd's 100-point modified Harris hip scoring system before arthroscopy and at 3, 6, 12, and 24 months after surgery.
The mean age of the ILP and NLP patients was 40 and 36 years, respectively, and their preoperative scores averaged 36 points. Mean joint distraction was 13 mm and 15 mm in the ILP and NLP patients, respectively, and a positive "Byrd's sign" was seen in both the ILP (84%) and NLP (42%) patients. After surgery, the ILP and NLP patients had 6-month scores that averaged 85 and 88 points, respectively. At 12 months, their scores averaged 88 and 90 points, respectively, and after 24 months, their scores averaged 88 and 89 points, respectively. At all follow-up intervals, there were no significant differences between the scores of the 2 groups (P > .05).
ILPs did not affect the 1- and 2-year clinical results of patients who sustained these injuries during hip arthroscopy.

记录医源性盂唇穿刺（ILP）对髋关节镜检查临床结果的影响。
从由资深作者进行的 250 例连续髋关节镜患者的数据库中，确定了 50 例存在 ILP 的患者。将这些患者的髋关节镜检查结果与未进行盂唇穿刺（NLP）的 50 例匹配患者的结果进行比较。所有髋关节均采用 Byrd 100 分改良 Harris 髋关节评分系统进行评估，在关节镜检查前以及术后 3、6、12 和 24 个月进行评估。
ILP 和 NLP 患者的平均年龄分别为 40 岁和 36 岁，术前评分平均为 36 分。ILP 和 NLP 患者的平均关节分离分别为 13mm 和 15mm，并且在 ILP（84%）和 NLP（42%）患者中均可见阳性“Byrd 征”。手术后，ILP 和 NLP 患者的 6 个月评分分别平均为 85 分和 88 分。12 个月时，他们的评分分别平均为 88 分和 90 分，24 个月后，他们的评分分别平均为 88 分和 89 分。在所有随访间隔，两组之间的评分均无显著差异（P＞.05）。
ILP 并未影响髋关节镜检查中发生这些损伤的患者在 1 年和 2 年的临床结果。
III 级，病例对照研究。
