This retrospective study aims to evaluate the radiographic, functional, and patient-derived outcomes of 16 patients who each received a Vitallium radial head prosthesis for unreconstructable acute fractures of the radial head, as well as previously treated fractures of the radial head associated with residual instability, pain, and stiffness. Follow-up averaged 33 months. A trend toward greater disability and poorer motion was noted in the delayed treatment group compared with the acute replacement group. Overall, the results were excellent in 5 patients, good in 10, and poor in 1, as determined by the Mayo Elbow Performance Score. All elbows were stable at follow-up, and no patient reported wrist pain. Four required further operative treatment of their elbow injuries. Metallic radial head arthroplasty yields satisfactory results in acute unreconstructable radial head fractures or as a salvage procedure for previously treated radial head fractures.
这项回顾性研究旨在评估16例患者的影像学、功能及患者自身报告的预后情况，这些患者均接受了维他灵（Vitallium）桡骨头假体置换，其中包括无法重建的桡骨头急性骨折患者，以及先前治疗过但伴有残留不稳定、疼痛和僵硬症状的桡骨头骨折患者。随访时间平均为33个月。与急性置换组相比，延迟治疗组患者的残疾程度更高、活动度更差。总体而言，根据梅奥肘关节功能评分，5例患者结果为优，10例为良，1例为差。所有肘关节在随访时均稳定，且无患者报告手腕疼痛。4例患者需要对肘部损伤进行进一步手术治疗。金属桡骨头置换术在急性不可重建性桡骨头骨折或作为先前治疗的桡骨头骨折的挽救手术中可取得令人满意的结果。
