Suprascapular neuropathy occurs when the suprascapular nerve is stretched or compressed. Because the shoulder blade has limited room for the nerve, a number of conditions can lead to compression, including cysts, excessive traction from a winged scapula, and rotator cuff tears.
Shoulder pain is the most common symptom of suprascapular neuropathy. The shoulder may also feel weak. In some cases, weakness will occur without pain.
In addition to assessing symptoms and a physical examination, there are a number of diagnostic studies that can help to identify suprascapular neuropathy. These tests include electromyography/nerve conduction studies, fluoroscopic (x-ray)-guided or ultrasound-guided injections, and MRI.
Suprascapular neuropathy can be treated with rest, pain medications, and physical therapy. In severe cases, surgery may be required.
