Management of Post-Surgical Shoulder Pain with Neuropathic Features

Initial Diagnostic Approach

The American College of Radiology recommends obtaining an MRI without IV contrast to evaluate for nerve compression, soft tissue pathology, and rotator cuff integrity in patients with prior shoulder repair and normal X-rays, presenting with electric shock sensation with overhead movements 1, 2
MRI without IV contrast is the primary next study for evaluating the postoperative shoulder when radiographs are noncontributory, as it can assess nerve structures, rotator cuff integrity, labral pathology, and soft tissue inflammation that may be causing nerve irritation, according to the American College of Radiology 1, 3

The American College of Radiology suggests that ultrasound may be preferred over MRI if there is significant metallic artifact from the prior repair hardware that would limit MRI examination quality, as ultrasound can effectively evaluate rotator cuff integrity and surrounding soft tissues in the postoperative setting 1, 3
However, ultrasound has limitations in evaluating deep structures and nerve pathology, making MRI the superior choice when nerve involvement is suspected, as stated by the American College of Radiology 1, 3

The American College of Radiology recommends starting neuromodulating medications such as gabapentin or pregabalin for the neuropathic pain component indicated by the electric shock sensation, in addition to NSAIDs and structured physical therapy focusing on scapular stabilization and avoiding provocative overhead positions initially 2
Patient education on activity modification, avoiding repetitive overhead movements that trigger symptoms during the acute phase, is also recommended by the American College of Radiology 2

The American College of Radiology advises against dismissing neuropathic symptoms as "normal postoperative pain", and instead recommends specific evaluation for nerve pathology and targeted treatment with neuromodulating agents rather than just NSAIDs 2
The American College of Radiology also recommends against ordering MR arthrography in the acute postoperative setting, as standard MRI without contrast is sufficient and appropriate for evaluating the postoperative shoulder 1
