我们回顾了39例移位的三部分和四部分肱骨骨折患者。在21名患者（A组）中，我们使用了解剖型假体作为肱骨头，在18名患者（13组）中使用了设计用于骨折的植入物。术后平均随访29.3个月时，总体Constant评分为51.9分; A组为51.5分，B组为52.4分。使用数字评定量表评估患者的主观满意度，两组患者的主观满意度相似。A组结节完全愈合率为29%，B组为50%。A组中29%的患者和B组中仅1例患者观察到部分整合，而A组中43%的患者和B组中44%的患者观察到吸收。结节完全或部分愈合的患者的功能结局明显更好（p = 0.022）。特定的创伤假体并没有导致结节更好的愈合。两种设计获得的临床结局差异未达到统计学显著性。
We reviewed 39 patients with displaced three- and four-part fractures of the humerus. In 21 patients (group A) we had used an anatomical prosthesis for the humeral head and in 18 (group 13) an implant designed for fractures.When followed up at a mean of 29.3 months after surgery the overall Constant score was 51.9 points; in group A it was 51.5 and in group B 52.4 points. The subjective satisfaction of the patients was assessed using a numerical rating scale and was similar in both groups. In group A complete healing of the tuberosities was found in 29% and 50% in group B. Partial integration was seen in 29% of group A and in only one patient in group B, while resorption was noted in 43% of group A and 44% of group B. The functional outcome was significantly better in patients with complete or partial healing of the tuberosities (p = 0.022). The specific trauma prosthesis did not lead to better healing of the tuberosities. The difference in clinical outcome obtained by the two designs did not reach statistical significance.
