Imaging and Conservative Management of Biceps Tendon Rupture

Diagnostic Imaging

Standard radiographs should be obtained first to exclude fractures and evaluate bony pathology in patients with suspected biceps tendon rupture. – American College of Radiology recommendation. 1
MRI of the shoulder or elbow without contrast is the gold‑standard modality for confirming a biceps tendon rupture and characterizing injury extent, offering a sensitivity of approximately 95 % and specificity of 95 %. – American College of Radiology guideline. 3
Ultrasound can be used as an alternative when experienced operators are available, but it provides lower diagnostic accuracy for partial tears (sensitivity ≈ 62.5 %, specificity ≈ 20 %). – American College of Radiology recommendation. 2
For distal biceps evaluation, a flexion‑abduction‑supination (FABS) MRI view improves visualization of the entire distal tendon and helps differentiate high‑grade partial tears from complete ruptures. – American College of Radiology guidance. 2

A non‑operative protocol consisting of relative rest with activity modification, ice for pain control, and a structured physical‑therapy program focusing on eccentric strengthening and stretching is advised for patients with proximal long‑head biceps ruptures. – American Family Physician clinical guidance. 4
Patients are instructed to gradually resume activities that do not exacerbate pain, ensuring a safe return to functional use. – American Family Physician protocol. 4

Reliance solely on physical examination may miss partial tears; imaging confirmation with MRI or ultrasound is recommended to avoid diagnostic errors. – American College of Radiology advisory. 2
