Minimally invasive (MI) total hip arthroplasty (THA) is an alternative to standard THA, but has created much controversy among orthopedic surgeons. The authors modified the original minimally invasive two-incision THA technique and used large-diameter (32 mm, 36 mm) ceramic-on-ceramic articulation.
One hundred and seventy patients that underwent unilateral MI two-incision THA were retrospectively reviewed, and surgical morbidity, functional recovery, radiological properties, and complications were assessed.
Mean Harris hip score (HHS) improved from 41.8 to 96.1 at last followup, and mean Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score from 66.2 to 26.9. The mean lateral opening angle of the acetabular component was 38.2° and the mean stem position was valgus 1.9°. There was an intraoperative femur fracture and one revision surgery due to stem subsidence. No patient had dislocation.
Our data suggest that this modified technique combined with large ceramic femoral head is safe and reproducible in terms of achieving proper implant positioning and early functional recovery.
微创全髋关节置换术（THA）是标准THA的一种替代方法，但在骨科医生中引发了诸多争议。作者对原始的微创双切口THA技术进行了改良，并采用了大直径（32毫米，36毫米）的陶瓷对陶瓷关节。
对170例行单侧微创双切口THA的患者进行回顾性研究，评估手术并发症、功能恢复情况、影像学特征及并发症。
末次随访时，平均Harris髋关节评分（HHS）从41.8提高至96.1，平均西安大略和麦克马斯特大学骨关节炎指数（WOMAC）评分从66.2降至26.9。髋臼组件的平均外侧开口角度为38.2°，股骨柄平均位置为外翻1.9°。术中发生1例股骨骨折，1例因股骨柄下沉行翻修手术。无患者发生脱位。
我们的数据表明，这种改良技术结合大尺寸陶瓷股骨头在实现正确的植入物定位和早期功能恢复方面是安全且可重复的。
