BACKGROUND
The aim of this survey was to show mid-term outcomes of a short-stem cementless hip prosthesis with metaphyseal fit and fill.
METHODS
Case series is on 74 implants in 67 patients, implanted from June 2006 to December 2010 with an average follow-up of 48 months (range 36-90 months).
RESULTS
In their case series, authors found some pitfalls as varus or valgus alignment, heterotopic ossification, aseptic mobilization with subsidency, and malpositioning. According to Harris Hip Score, postoperative clinical outcomes were excellent-good (84 %) and fair-poor (16 %).
CONCLUSIONS
At a mid-term follow-up, the investigated implant showed a strong stability and some well-tolerated mechanical and biological pitfalls.
背景
本调查的目的是展示具有干骺端贴合与填充的短柄非骨水泥型髋关节假体的中期结果。
方法
该病例系列研究了67例患者的74枚植入物，于2006年6月至2010年12月植入，平均随访48个月（范围36 - 90个月）。
结果
在他们的病例系列中，作者发现了一些问题，如内翻或外翻对线、异位骨化、伴有下沉的无菌性松动以及位置不当。根据Harris髋关节评分，术后临床结果为优 - 良（84%）和中 - 差（16%）。
结论
在中期随访中，所研究的植入物显示出较强的稳定性以及一些耐受性良好的机械和生物学问题。
