The purpose of this study was to retrospectively assess patients treated with modular, non-cemented, tapered, fluted, distal fixation stems. We included patients with 24 months mínimum follow-up. Diagnosis that led to revisions were described. The radiographic analysis was made with preoperative, immediate postoperative and last control postoperative X-rays. Sixty-seven patients met inclusion criteria. We observed 59,7% (n=40) Osteointegration, 34,3% of Stable Fibrosis and 5,97% Unstable fibrosis. Stress Shielding was registered with 10,44% and Subsidence was observed in 34,3% of the patients. Modular, fluted, tapered, distal fixation stems have an excellent survival rates.
本研究的目的是回顾性评估接受模块化、非骨水泥型、锥形、带槽、远端固定柄治疗的患者。我们纳入了至少随访24个月的患者。描述了导致翻修的诊断情况。通过术前、术后即刻和末次随访术后X线片进行影像学分析。67例患者符合纳入标准。我们观察到59.7%（n = 40）的骨整合、34.3%的稳定纤维组织和5.97%的不稳定纤维组织。应力遮挡发生率为10.44%，34.3%的患者出现下沉。模块化、带槽、锥形、远端固定柄具有出色（优异）的生存率。 （注：“mínimum”疑似拼写错误，应为“minimum” ；“excellent survival rates”直译为“出色的生存率”，结合语境这里用“优异的生存率”表述可能更合适，但按要求未做修改）
