The objective of this study was to evaluate the early results of a custom non-fluted diaphyseal press-fit stem for use with the global modular replacement system (GMRS) tumour prosthesis and the early complications associated with this implant.
A total of 53 patients (54 implants) were identified from a prospective database where a custom non-fluted diaphyseal press-fit stem was used as part of the reconstruction of the limb. All patients had a minimum of 22 months of follow-up.
The rates of stem revision for any reason were calculated. The median follow-up was 36 months (range 22-85 months). Aseptic loosening was not observed in any patient.
At early term follow-up, an uncemented non-fluted stem used with the GMRS tumour endoprosthesis provides a stable bone-prosthesis interface with no evidence of aseptic loosening.
本研究旨在评估全球模块化置换系统(GMRS)肿瘤假体使用的定制非开槽骨干压配合式假体的早期结果,以及与该植入物相关的早期并发症。
从一个前瞻性数据库中确定了 53 名患者(54 个植入物),其中使用定制的非开槽骨干压配合式假体作为肢体重建的一部分。所有患者的随访时间均至少为 22 个月。
计算了任何原因的干细胞翻修率。中位随访时间为 36 个月(范围 22-85 个月)。任何患者均未观察到无菌性松动。
在早期随访中,与 GMRS 肿瘤假体一起使用的非骨水泥非开槽干骺端假体提供了稳定的骨-假体界面,没有无菌性松动的证据。
