UNASSIGNED: A consecutive series of 395 shoulders (225 male, 170 female) over a 19-year period (2000-2019) with a minimum follow-up of 2 years were analyzed. Outcome measures were length of stay, operating time, satisfaction visual analog score (VAS), pain VAS, Oxford Shoulder Score (OSS), Constant-Murley score, range of movement, complications, and implant survival.
UNASSIGNED: The incidence of a diagnosis of osteoarthritis as the surgical indication increased over time. The number of cases by surgeon per year increased from three cases in 2,000 to a peak of 33 in 2011. Up to seven implant manufacturers were used. The incidence of hemiarthroplasties decreased, and more numerous reverse polarity and anatomic arthroplasties were performed (P<0.001). More glenoid and humeral components were cemented and more short-stem implants were used in later years (P<0.001). Length of stay was a median of 1 day with a trend towards daytime surgery in recent years. Patients were satisfied (VAS 8/10) and OSS improved by 8 points on average throughout the observation period.
UNASSIGNED: Despite frequent introductions of new implants, patient outcome, satisfaction, and complication rates remained good. There appears to be a need for large-scale, generalizable studies to understand why technological advancements leading to changes in implants do not influence clinical outcomes. Level of evidence: III.
■连续395个肩膀(225个男性,分析了170名女性),历时19年(2000-2019年),最少随访2年。结果衡量标准是停留时间,操作时间,满意度视觉模拟评分(VAS),疼痛VAS,牛津肩评分(OSS),Constant-Murley得分,运动范围,并发症,和植入物存活。
■作为手术指征的骨关节炎的诊断发生率随时间增加。外科医生每年的病例数量从2,000例中的3例增加到2011年的33例峰值。使用了多达七个植入物制造商。半关节置换术的发生率下降,进行了更多的反极性和解剖关节置换术(P<0.001)。更多的关节盂和肱骨组件被骨水泥化,更多的短柄植入物在以后的几年中被使用(P<0.001)。住院时间的中位数为1天,近年来有白天手术的趋势。患者满意(VAS8/10),OSS在整个观察期间平均提高8分。
■尽管经常引入新的植入物,患者结果,满意,并发症发生率保持良好。似乎需要大规模,可推广的研究,以了解为什么导致植入物变化的技术进步不会影响临床结果。证据等级:III.
