概括

定制的大假肢 (CUMP) 提供了一个可靠的解决方案,用于具有骨损失的挑战性修复全肘关节整形术 (rTEA) 病例. 这项研究表明,CUMP在非瘤适应症中的早期到中期结果良好,患者报告的结果令人满意.

科学领域:

整形外科手术整形外科手术
生物医学工程生物医学工程

背景情况:

修复全肘关节整形术 (rTEA) 的数量越来越多,由于靠近腰部的骨损失,这给人带来了挑战.
存在有限的治疗选择,包括冲击移植,支架全移植和全移植假肢复合材料.
定制椎巨假体 (CUMP) 是一个可行的选择,但其用于非瘤修复TEA的证据很少.

研究的目的:

评估定制大假肢 (CUMP) 的临床和放射性结果,用于修复全肘关节整形手术 (rTEA) 的非瘤指示.
评估CUMP在复杂情况下的安全性和有效性,其中包括显著的近端骨损失.

主要方法:

在第三级推中心对接受rTEA的CUMP患者的回顾性审查.
数据收集包括人口统计,适应症,之前的手术,随访时间,运动范围,并发症和患者报告的结果 (牛津肘部得分,疼痛,EQ5D,SANE).
进行了骨损失 (曼萨特分级) 和植入物稳定性的放射性评估.

主要成果:

该队列包括15名肘部患者,平均随访时间为2年;平均先前的手术次数为3.
症状包括感染 (8),周围假肢骨折 (4) 和无菌松动 (3).
观察到良好的早期到中期临床结果,运动范围和患者报告的得分有所改善;并发症很低,有两例复发性深层感染.

结论:

定制大假肢 (CUMP) 在非瘤病例中表现出良好的早期到中期临床和放射性结果,用于修复全肘关节整形术 (rTEA).
并发症率相对较低,患者报告的结果令人满意,表明CUMP是一个可靠的解决方案.
精心规划对于在具有挑战性的RTEA场景中成功实施CUMP至关重要.

Bones of the Upper Limb: Ulna

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Bones of the Upper Limb: Humerus

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
