The relationship between hip rotational abnormalities and hip labral size has not been fully investigated.
To (1) examine the correlation between rotational abnormalities of the hip and labral size, while also identifying other predictive values for hip labral size, and (2) explore whether femoral torsion will lead to increased labral size.
Cross-sectional study; Level of evidence, 3.
A total of 180 patients (180 hips) with femoroacetabular impingement syndrome (FAIS) (mean age, 36.81 ± 10.17 years; 67 male, 113 female) who underwent hip arthroscopic surgery between January 2021 and May 2022 were included. The femoral version (FV), acetabular version, and combined version angles were measured on computed tomography, and the labral length and height at the 12-o'clock and 3-o'clock positions were measured on magnetic resonance imaging. The hips were categorized into 3 groups based on FV angle: small (SFV; <10°); moderate (MFV; ≥10° and ≤20°), and large (LFV; >20°), and group comparisons were performed. Linear correlation and regression analysis were employed.
Predictive factors for labral length were FV angle (β = 0.298; = .02), sex (β = -0.302; < .001), and age (β = -0.169; = .016) at 3 o'clock and lateral center-edge angle (LCEA; β = -0.208; = .005) and age (β = -0.186; = .011) at 12 o'clock. FV angle was positively correlated with labral length at 3 o'clock ( = 0.267; < .001) and negatively correlated with age ( = -0.222; = .003) and female sex ( = -0.202; = .006). LCEA ( = -0.227; = .002) and age ( = -0.205; = .006) were negatively correlated with labral length at 12 o'clock. Labral length at 3 o'clock was significantly different between the LFV (n = 49 hips), MFV (n = 65 hips), and SFV (n = 66 hips) groups (9.85 ± 2.28, 8.89 ± 2.44, and 8.30 ± 2.05 mm, respectively; = .027 for LFV vs MFV; < .001 for LFV vs SFV).
Patients with FAIS who exhibited a higher FV angle were at a greater likelihood of having a larger anterior labral length. Increased femoral anteversion and decreased LCEA, male sex, and younger age were significantly associated with longer hip labral length.
髋部旋转异常与髋臼盂唇大小之间的关系尚未得到充分研究。
（1）研究髋部旋转异常与盂唇大小之间的相关性，同时确定髋臼盂唇大小的其他预测因素；（2）探讨股骨扭转是否会导致盂唇大小增加。
横断面研究；证据等级，3级。
纳入2021年1月至2022年5月期间接受髋关节镜手术的180例股骨髋臼撞击综合征（FAIS）患者（180髋）（平均年龄36.81±10.17岁；男性67例，女性113例）。在计算机断层扫描上测量股骨扭转角（FV）、髋臼扭转角和联合扭转角，在磁共振成像上测量盂唇在12点和3点位置的长度和高度。根据FV角将髋关节分为3组：小（SFV；<10°）；中（MFV；≥10°且≤20°）和大（LFV；>20°），并进行组间比较。采用线性相关和回归分析。
3点位置盂唇长度的预测因素为FV角（β = 0.298；P = 0.02）、性别（β = -0.302；P < 0.001）和年龄（β = -0.169；P = 0.016），12点位置为外侧中心边缘角（LCEA；β = -0.208；P = 0.005）和年龄（β = -0.186；P = 0.011）。FV角与3点位置盂唇长度呈正相关（r = 0.267；P < 0.001），与年龄（r = -0.222；P = 0.003）和女性性别（r = -0.202；P = 0.006）呈负相关。LCEA（r = -0.227；P = 0.002）和年龄（r = -0.205；P = 0.006）与12点位置盂唇长度呈负相关。3点位置盂唇长度在LFV组（49髋）、MFV组（65髋）和SFV组（66髋）之间有显著差异（分别为9.85±2.28、8.89±2.44和8.30±2.05mm；LFV与MFV比较，P = 0.027；LFV与SFV比较，P < 0.001）。
FV角较高的FAIS患者更有可能有较长的前盂唇长度。股骨前倾角增加、LCEA减小、男性性别和较年轻年龄与较长的髋臼盂唇长度显著相关。
