■几个变量可能会影响髋关节镜检查过程中的牵引力。具体来说,髋关节旋转的程度可能会影响髋关节镜检查中牵引力的大小。然而,目前对这个特定问题的研究有限。
■量化在各种牵引状态和旋转位置下施加在被拉动肢体上的牵引力。此外,这项研究旨在调查股骨前倾之间的潜在相关性,BMI,麻醉方法,和髋关节脱位所需的牵引力。
■假设不同牵引状态和旋转位置的牵引力会有所不同,并且股骨前倾,体重指数(BMI),麻醉方法可能会影响所需的牵引力。
■横断面研究;证据水平,4.
■在2022年6月至12月期间参加我们部门运动医学诊所并接受关节镜手术以诊断股骨髋臼撞击的患者进行了回顾性评估。测量了以下6个关键时间点的牵引力-初始牵引力,牵引到可操作宽度,关节穿刺后,囊切开术后,在囊切开术后20分钟,在囊切开术后40分钟。在每个州,髋关节旋转到内部旋转位置,外部旋转位置,中立立场。记录并分析了不同状态和位置下的牵引力。通过方差分析和Tukey方法测试了不同关节囊物理状态和旋转位置之间的牵引力差异。采用Pearson检验分析不同组BMI与股骨前倾的相关性。
■本研究共纳入41例患者。牵引力在达到可手术宽度后增加,在囊切开术后明显减少(P<0.05)。此后,牵引力随时间逐渐降低(P<0.05)。外部和内部旋转位置的牵引力明显大于中立位置的牵引力,在所有牵引状态下(P<.05)。此外,内部位置和中立位置之间的牵引力差异,以及外部和中立位置之间的牵引力差异,发现在所有牵引状态下,内部和外部旋转位置之间的牵引力差异显着较大(P<.05)。髋关节不同旋转位置的牵引力之间的差异与股骨前倾呈负相关(状态3,4和5中中性-内部的Pearson相关系数分别为-0.33,-0.31,-0.31;P<.05),与BMI呈正相关(状态4和6中外部中性的Pearson相关系数分别为0.33和0.36;P<.05)。
■我们的发现表明,在关节穿刺和囊切开术后,牵引力降低,并且在手术过程中随时间降低。外部或内部旋转增加了牵引力。股骨前倾较高或BMI较低的患者可能需要较低的牵引力。这些数据可能有助于最小化牵引力,以帮助防止髋关节镜检查期间由于牵引引起的并发症。
UNASSIGNED: Several variables may affect the traction force during hip arthroscopy. Specifically, the degree of hip joint rotation may influence the magnitude of traction force during hip arthroscopy. However, there is currently limited research available on this particular issue.
UNASSIGNED: To quantify the
traction force applied to the pulled limb in various
traction states and rotational positions. Additionally, the study aimed to investigate potential correlations between femoral anteversion, BMI, anesthesia methods, and the traction force required for hip dislocation.
UNASSIGNED: It was hypothesized that
traction force in different
traction states and rotational positions would be different and that femoral anteversion, body mass index (BMI), and anesthesia methods may influence the traction force needed.
UNASSIGNED: Cross-sectional study; Level of evidence, 4.
UNASSIGNED: Patients who attended the sports medicine clinic of our department and underwent arthroscopic surgery for the diagnosis of femoroacetabular impingement between June and December 2022 were retrospectively evaluated. The
traction force at the following 6 key timepoints was measured-initial
traction,
traction to the operable width, after joint puncture, after capsulotomy, at 20 minutes after capsulotomy, and at 40 minutes after capsulotomy. In each state, the hip was rotated to the internal rotational position, external rotational position, and neutral position. The traction force at different states and positions was recorded and analyzed. The differences in traction force between the different joint capsular physical states and rotational positions were tested by analysis of variance and the Tukey method. The Pearson test was used to analyze the correlation between BMI and femoral anteversion in different groups.
UNASSIGNED: A total of 41 patients were included in this study. The traction force increased after reaching the operable width and decreased significantly after capsulotomy (P < .05). Thereafter, the traction force decreased gradually over time (P < .05). Traction force in the external and internal rotational positions was significantly greater than that in the neutral position, across all states of traction (P < .05). Furthermore, the difference in traction force between the internal and neutral positions, as well as the difference in traction force between the external and neutral positions, was found to be significantly greater than the difference in traction force between the internal and external rotational positions in all
traction states (P < .05). The difference between the traction forces in different rotational positions of the hip joint exhibited a negative correlation with femoral anteversion (Pearson correlation coefficient of neutral-internal in states 3, 4, and 5 was -0.33, -0.31, -0.31, respectively; P < .05) and a positive correlation with BMI (Pearson correlation coefficient of external-neutral in states 4 and 6 was 0.33 and 0.36, respectively; P < .05).
UNASSIGNED: Our findings show that the traction force decreased after joint puncture and capsulotomy and decreased over time during surgery. External or internal rotation increased the traction force. Patients with higher femoral anteversion or lower BMI may need lower traction force. These data may help in minimizing
traction forces to help prevent complications due to
traction during hip arthroscopy.
