摘要

简介：这项研究调查了接受两阶段双侧全髋关节置换术（THA）的患者在使用Corail柄进行初级全髋关节置换术（THA）后的柄下沉情况。第二项研究结果是探讨特定的单一皮质骨接触点是否可减少术后柄下沉：本研究根据STROBE指南进行。方法：本研究按照STROBE指南进行。研究人员查阅了2016年至2023年间接受THA手术的患者记录。检索了所有接受两阶段双侧 THA 的患者。在骨盆的前正位X光片（内侧和外侧骨接触）和髋关节的Lauenstein视图（前方和后方骨接触）中，对骨骺和骨干远端（干骺端）各点的骨干和皮质骨之间的直接接触进行了评估。测量并比较以下参数以评估股骨柄下沉：股骨柄骨界面处股骨近端到小转子顶端的距离（距离A）；小转子顶端到股骨柄顶端的距离（距离B）：共纳入250名患者，其中45%（250名患者中的149名）为女性，61%（250名THA患者中的153名）主要植入右侧。患者首次接受 THA 时的平均年龄为 64.3 ± 10.0 岁，平均体重指数（BMI）为 28.0 ± 4.9 kg/m2。平均随访时间为（14.1 ± 10.8）个月。THA 术后的总体骨干下沉为 2.8 ± 0.7 毫米（P 0.5）。使用无领无骨水泥Corail柄进行THA后，14个月时柄下沉约为2.8毫米：结论：使用Corail骨干进行THA后，骨干在干骺端和干骺端的直接皮质骨接触似乎不会影响骨干下沉。

Subsidence of the Corail stem in total hip arthroplasty: no influence of bony contact.

Introduction: This study investigated stem subsidence following primary total hip arthroplasty (THA) with a Corail stem in patients who underwent two-staged bilateral THA. The second outcome of interest was to investigate whether a specific single cortical bone contact point might reduce postoperative stem subsidence.

Methods: The present study was conducted following the STROBE guidelines. The records of patients who underwent THA between 2016 and 2023 were accessed. All patients who underwent two-staged bilateral THA were retrieved. The direct contact between the stem and the cortical bone was assessed at various points in the metaphysis and the distal portion of the stem (diaphysis) in both anteroposterior radiographs of the pelvis (medial and lateral bone contact) and a Lauenstein view of the hip (anterior and posterior bone contact). The following parameters were measured and compared to assess stem subsidence: distance from the proximal femur at the stem bone interface and the tip of the lesser trochanter (distance A); distance from the tip of the lesser trochanter and the tip of the femoral stem (distance B).

Results: In total, 250 patients were included, 45% (149 of 250 patients) were women and 61% (153 of 250 THAs) were implanted primarily on the right side. The mean age of patients at the time of the first THA was 64.3 ± 10.0 years and the mean body mass index (BMI) was 28.0 ± 4.9 kg/m². The mean length of the follow-up was 14.1 ± 10.8 months. The overall stem subsidence following THA was 2.8 ± 0.7 mm (P < 0.006). A direct cortical bone-implant contact did not exert a statistically significant difference in subsidence of the THA stem at the metaphysis and diaphysis (P > 0.5). Stem subsidence following THA with a collarless cementless Corail stem was approximately 2.8 mm at 14 months.

Conclusions: Direct cortical bone contact of the stem at diaphysis and metaphysis seems not to influence stem subsidence following THA using the Corail stem.
