INTRODUCTION
Total hip arthroplasty is a widespread treatment and is considered the gold standard in cases of hip osteoarthritis, with high rates of success in improving pain and function when well performed. After five years of follow-up, this study evaluates the osseointegration of uncemented Targos® collared stems in arthroplasties.
METHODS
Observational study of 182 total hip arthroplasties performed in 2014 with Targos® cementless collared femoral stems (Lepine). Bone quality was assessed according to the Dorr scale and osseointegration according to the Engh score.
RESULTS
The overall mean age was 56.5 years, consisting of 104 men (57.1%) and 103 women (56.6%). The osseointegration rate of the stems (total Engh>0) was 100%. There was no statistical difference between groups concerning age (p=0.262), gender (p=0.463), primary diagnosis (p=0.585), affected side (p=0.459), and degree of Dorr (p=0.857).
CONCLUSION
Targos® cementless collared femoral stems showed excellent osseointegration in all patients evaluated, regardless of age, gender, and preoperative bone quality. Moreover, spot welds observed on preoperative radiographs have the best association with implant osseointegration. .
引言
全髋关节置换术是一种广泛应用的治疗方法，被认为是髋关节骨关节炎病例的金标准，若手术操作得当，在改善疼痛和功能方面成功率很高。经过五年的随访，本研究评估了非骨水泥型Targos®带领股骨柄在关节置换术中的骨整合情况。
方法
对2014年采用Targos®非骨水泥带领股骨柄（Lepine）进行的182例全髋关节置换术进行观察性研究。根据Dorr量表评估骨质量，根据Engh评分评估骨整合情况。
结果
总体平均年龄为56.5岁，其中男性104例（57.1%），女性103例（56.6%）。股骨柄的骨整合率（Engh总分>0）为100%。在年龄（p=0.262）、性别（p=0.463）、初步诊断（p=0.585）、患侧（p=0.459）和Dorr分级（p=0.857）方面，各组之间无统计学差异。
结论
无论年龄、性别和术前骨质量如何，Targos®非骨水泥带领股骨柄在所有评估患者中均显示出良好的骨整合。此外，术前X线片上观察到的点焊与植入物骨整合的相关性最佳。
