Abstract

Background: Magnetic resonance imaging (MRI) is commonly used to diagnose and assess the extent of partial distal biceps injuries. The aim of this study was to report on the accuracy of MRI and the effect of injury history and study timing on its performance.

Methods: A retrospective review of all patients who underwent surgical treatment of partial thickness distal biceps tears at a single center by multiple surgeons was performed. Inclusion criteria consisted of the performance of a preoperative MRI and documentation of the intraoperatively visualized extent of the tear, and 68 patients met the criteria for inclusion. A chart review was completed to evaluate the symptom duration, injury history, and tear extent.

Results: All patients had distal biceps tears of greater than 50% intraoperatively. However, MRI did not indicate any tearing in 20 (29%) patients, and its sensitivity for high-grade tear was 44%. Magnetic resonance imaging was significantly less likely to be read as high-grade tears in patients with insidious onset of their symptoms in comparison with patients who reported a traumatic onset (27% vs 55%, P = .024). However, the time from symptom onset to MRI did not significantly correlate with diagnosis of a high-grade tear on MRI (r = -0.15, P = .21).

Conclusions: These results indicate that MRI can underreport partial distal biceps tear extent, and this more commonly occurs in patients with insidious onset of pain.

MRI评估高级别肱二头肌远端部分撕裂的准确性。
背景:磁共振成像(MRI)通常用于诊断和评估部分远端肱二头肌损伤的程度。本研究的目的是报道MRI的准确性以及损伤史和研究时间对其性能的影响。方法:回顾性分析所有接受单中心手术治疗的肱二头肌远端部分厚度撕裂的患者。纳入标准包括术前MRI表现和术中撕裂程度的记录,68例患者符合纳入标准。回顾图表以评估症状持续时间、损伤史和撕裂程度。结果:所有患者术中二头肌远端撕裂率均大于50%。然而,20例(29%)患者的MRI未显示任何撕裂,其对高度撕裂的敏感性为44%。与报告创伤性发作的患者相比,具有隐匿性发作症状的患者的磁共振成像被解读为高级别撕裂的可能性显着降低(27% vs 55%, P = 0.024)。然而,从症状出现到MRI检查的时间与MRI诊断的高级别撕裂没有显著相关性(r = -0.15, P = 0.21)。结论:这些结果表明,MRI可以低估部分远端二头肌撕裂程度,这更常见于潜伏性疼痛的患者。
