The aim of this retrospective study was to undertake a comparative evaluation of the Evolve modular metallic radial head implant prosthesis and the MoPyC pyrocarbon prosthesis in acute care. Seventyfive patients having a comminuted radial head fracture with an Evolve prosthesis (=G1) and 11 with a MoPyC prosthesis (=G2) were available for a follow-up. Postoperative patient outcomes were evaluated according to a standardized follow-up protocol which included the Morrey rating system. Assessment criteria were range of motion (ROM), functional scores, and rate of complications. G1 showed a mean Morrey score of 86 points. Four direct prosthesis complications were observed in this group (n=75). The average achieved Morrey score in G2 was 84 points. In this group (n=11), 2 direct prosthesis complications were diagnosed. The average range of motion did not differ greatly between both groups. Radial head replacement with either prosthesis yielded sufficient to satisfactory results in a mid-term perspective regarding the range of motion and function of the elbow joint when performed in carefully selected patients. The Evolve Prothesis appears to show a slightly lower rate of complication by way of a similar functional outcome.
这项回顾性研究的目的是对Evolve模块化金属桡骨头植入假体和MoPyC热解碳假体在急性护理中的情况进行比较评估。75例使用Evolve假体（=G1组）和11例使用MoPyC假体（=G2组）的粉碎性桡骨头骨折患者可供随访。根据包括Morrey评分系统在内的标准化随访方案评估术后患者的预后。评估标准为活动范围（ROM）、功能评分和并发症发生率。G1组的平均Morrey评分为86分。该组（n = 75）观察到4例直接假体并发症。G2组的平均Morrey评分为84分。该组（n = 11）诊断出2例直接假体并发症。两组之间的平均活动范围差异不大。在精心挑选的患者中进行桡骨头置换时，从肘关节活动范围和功能的中期角度来看，两种假体都能产生足够至令人满意的结果。Evolve假体在功能结果相似的情况下，并发症发生率似乎略低。
