This study aimed to investigate the relationship between hip muscle mass and patient-reported outcomes (PROs) after total hip arthroplasty (THA) surgery for hip disease using 3D volumetric measurements of the gluteus muscle group and iliac muscle.
Between January 2020 and December 2021, 85 patients who had undergone unilateral THA for osteoarthritis or osteonecrosis of the femoral head were enrolled. Using a 3D modeler program, automatically generated 3D reconstructed images of the hip muscles were obtained, and volumetric measurements were performed. Both unadjusted and height (m)-adjusted muscle volumes of the gluteus maximus (unadjusted volume: GmaxV; adjusted volume: GmaxI), gluteus medius (unadjusted volume: GmedV; adjusted volume: GmedI), gluteus minimus (unadjusted volume: GminV; adjusted volume: GminI), and iliacus (unadjusted volume: IliacV; adjusted volume: IliacI) muscles were measured on the affected side and both sides. Pearson correlation analysis between muscle volumes and postoperative 12-month PROs were performed.
The preoperative Gmax volume on the affected side was significantly associated with post-operative PROs, especially mHHS (GmaxV: = 0.026; GmaxI: = 0.005) and UCLA scores (GmaxV: = 0.006; GmaxI: = 0.002). For measurements on both sides, Gmed volume was the sole index showing a significant correlation with postoperative UCLA scores (GmedV: = 0.023; GmedI: = 0.043).
The current study suggests that preoperative gluteus muscle volume may have predictive value for postoperative PROs of hip disease patients who have undergone THA surgery.
本研究旨在通过对臀肌群和髂肌进行三维容积测量，探讨髋关节疾病全髋关节置换术（THA）后髋部肌肉质量与患者报告结局（PROs）之间的关系。
2020年1月至2021年12月，纳入85例行单侧THA治疗股骨头骨关节炎或骨坏死的患者。使用三维建模程序，获得自动生成的髋部肌肉三维重建图像，并进行容积测量。测量患侧及双侧臀大肌（未调整容积：GmaxV；调整容积：GmaxI）、臀中肌（未调整容积：GmedV；调整容积：GmedI）、臀小肌（未调整容积：GminV；调整容积：GminI）和髂肌（未调整容积：IliacV；调整容积：IliacI）的未调整和身高（米）调整后的肌肉容积。对肌肉容积与术后12个月的PROs进行Pearson相关分析。
患侧术前Gmax容积与术后PROs显著相关，尤其是改良Harris髋关节评分（mHHS）（GmaxV：=0.026；GmaxI：=0.005）和加州大学洛杉矶分校（UCLA）评分（GmaxV：=0.006；GmaxI：=0.002）。对于双侧测量，Gmed容积是唯一与术后UCLA评分显著相关的指标（GmedV：=0.023；GmedI：=0.043）。
本研究表明，术前臀肌容积可能对接受THA手术的髋部疾病患者的术后PROs具有预测价值。
