OBJECTIVES: The purpose of this study is to evaluate a consecutive series of proximally porous-coated hemiarthroplasty for the treatment of severe @entity6342 with special emphasis on @entity1349 and functional outcome. DESIGN: Observational cohort of a consecutive series of a single prosthetic design. SETTING: Orthopaedic clinic, nonacademic institutional hospital. @entity1 / @entity1 : All @entity1 (n = 30) treated with hemiarthroplasty for severe @entity174 of the proximal humerus with informed consent and at least 1 year follow-up were included. Follow-up averaged 37 months (range, 13-62 months). INTERVENTION: Uncemented proximally porous-coated hemiarthroplasty. MAIN OUTCOME MEASUREMENTS: We evaluated clinical and radiologic @entity1349 , Constant score, @entity1 satisfaction and visual analog scale score, range of motion, radiologic parameters such as head-to-tuberosity distance, lateral projection, and lateral offset. RESULTS: : The overall Constant score was 68 (standard deviation [SD] 18), the mean @entity1 satisfaction 7.1 (SD 1.8), and the average visual analog scale score 3.7 (SD 2.5). We observed no cases of radiographic tilting or subsidence. In 17 cases (57%), radiolucent lines 1.0 mm or less were observed in less than three zones. None of the cases met the criteria for radiographic loosening. No revision was performed for @entity1349 . The average head-to-tuberosity distance was 7.6 (SD 8.7 mm). We found that traumatic neurologic deficit and head-to-tuberosity distance significantly influenced Constant score. Lateral projection significantly correlated with Constant score, active forward flexion, and abduction. CONCLUSIONS: Proximally porous-coated hemiarthroplasty is a valuable alternative alongside cemented hemiarthroplasty for the treatment of severe @entity174 of the proximal humerus. The radiographic finding of increased lateral projection was associated with an improved range of motion.
