Suprascapular Nerve Compression Research Articles

Glenoid cysts mimicking cervical radiculopathy.

Patients are often referred for the evaluation of neck or radiating shoulder or arm pain who are suspected of having a possible cervical spine origin of their symptoms. Careful evaluation may show ganglion cysts of the glenohumeral joint mimicking symptoms of cervical radiculopathy. To present a series of patients in whom cysts originating from the glenohumeral joint caused symptoms mimicking cervical radiculopathy. Suprascapular nerve entrapment in the suprascapular notch by ganglion cysts from the glenohumeral joint has been described as the source of vague radicular symptoms. This paper presents a series of patients referred to a spine practice for the evaluation of cervical radiculopathy who actually had glenoid cysts mimicking cervical radiculopathy. Three hundred forty-two patients were evaluated for cervical radiculopathy; of these, eight had glenoid cysts that were the source of the patients' symptoms. All eight patients had a positive shoulder impingement sign, or, in all, symptoms were temporarily relieved with intra-articular lidocaine injection. Four of the eight patients had abnormal electromyelography and nerve conduction velocity for suprascapular nerve compression. Magnetic resonance imaging of the shoulder was diagnostic in all eight patients. Proper evaluation of the shoulder must be done because it may mimic symptoms of cervical radiculopathy.

Shoulder Pain Due to Suprascapular Nerve Compression During General Anesthesia

Suprascapular nerve entrapment is an uncommon but often under-recognized entity caused by a variety of mechanisms and injuries to the shoulder area. The case presented is of a patient with neuropathy after a bilateral hernia repair. This is a previously undocumented association not closely adhering to the usually proposed mechanisms of injury. These mechanisms and the diagnosis and treatment of suprascapular nerve compression are reviewed.

Supracapular nerve entrapment

Suprascapular nerve compression is a true peripheral entrapment neuropathy that can be cured by lysis of the suprascapular ligament and freeing the suprascapular nerve. It is a rare entity that must be considered in the differential diagnosis of radicular pain, as well as that of the shoulder. Four examples of suprascapular nerve neuropathy in three patients are described, including one case of bilateral entrapment; all were young females. One was diagnosed as systemic lupus erythematosus (case 3); it is now considered that a second patient (case 2) may have the same disorder. The clinical, anatomic, and surgical considerations of the suprascapular nerve are considered in this paper.
