Fluoroscopic-guided supra-scapular nerve block in the management of shoulder pain in a Nigerian Teaching Hospital: Report of five cases.

Abstract

Shoulder pain complaints are common in our environment. The disorder can occur among the young active age group or in the older patients as a result of degenerative changes with its attendant limitations of the function of the affected upper limb, hindrance of the performance of activities of daily living, and reduced quality of life. The traditional oral analgesics, physiotherapy, and intra-articular corticosteroid injections are seldom ineffective at providing the desired pain relief and functional improvement at the shoulder joint. We investigated the role of fluoroscopic-guided supra-scapular nerve blocks (SSNBs) in patients with shoulder pain who failed to respond to the routine conservative management. With the patient lying prone and the C-arm fluoroscope placed in anterior-posterior position, the scapula notch was visualized and a 22G spinal needle was directed toward the nerve. The mixture of local anesthetic agent and steroid was injected as close to the nerve as possible after negative aspiration. Fluoroscopic-guided SSNB can produce substantial pain relief and improved range of movement in patients with painful shoulders. The procedure is safe, well tolerated, and can be done on a day-case basis.
