The aim of this study was to evaluate risk factors for symptomatic hardware and removal of hardware (ROH) after olecranon open reduction and internal fixation (ORIF) and to assess differences between olecranon locking plate and screws (P&S) or tension band (TB) wire cohorts. The medical records of 331 patients with olecranon fractures treated at two academic level I trauma centers with ORIF from 2012 to 2016 were reviewed. A total of 189 patients were included in the study. Complications, ROH, and subsequent surgery were assessed and compared between cohorts. There were 124 cases in the P&S cohort and 65 in the TB cohort. The overall reoperation rate was 31.2% (59 of 189). The overall incidence of ROH for all cases was 29.1% (55 of 189). Patients who required ROH or developed symptomatic hardware were significantly younger than those who did not (P&S, P<.003; TB, P<.004). Age and body mass index (BMI) were associated with ROH plus symptomatic hardware after P&S. Age (but not BMI) was associated with ROH/symptomatic hardware after TB. Measured hardware prominence was not associated with ROH or ROH plus symptomatic hardware for either the P&S or the TB cohort. Risk factors including patient age and BMI were found to be significantly associated with hardware-related complications. [Orthopedics. 2020;43(3):141-146.].
本研究的目的是评估尺骨鹰嘴切开复位内固定术（ORIF）后出现症状性内固定物及取出内固定物（ROH）的危险因素，并评估尺骨鹰嘴锁定钢板和螺钉（P&S）或张力带（TB）钢丝队列之间的差异。回顾了2012年至2016年在两个一级学术创伤中心接受ORIF治疗的331例尺骨鹰嘴骨折患者的病历。共有189例患者纳入研究。对各队列的并发症、ROH及后续手术进行评估和比较。P&S队列有124例，TB队列有65例。总体再次手术率为31.2%（189例中的59例）。所有病例的ROH总发生率为29.1%（189例中的55例）。需要ROH或出现症状性内固定物的患者明显比未出现的患者年轻（P&S，P<0.003；TB，P<0.004）。P&S术后，年龄和体重指数（BMI）与ROH加症状性内固定物相关。TB术后，年龄（而非BMI）与ROH/症状性内固定物相关。对于P&S或TB队列，测量的内固定物突出程度与ROH或ROH加症状性内固定物均无关。发现包括患者年龄和BMI在内的危险因素与内固定物相关并发症显著相关。[《骨科》。2020；43(3):141 - 146。]
