C5 Nerve Root Palsy: An Uncommon Postoperative Complication and Its Management.

The standard treatment for multiple levels of cervical prolapsed intervertebral disk (PIVD) is anterior cervical decompression and fusion. Although it is associated with positive outcomes, it is also fraught with complications. In this report, we present an unusual postoperative case of a 58-year-old male who underwent anterior decompression and cervical fusion at two levels - C4-C5 and C5-C6 - for traumatic PIVD and developed a postoperative complication of unilateral C5 motor palsy, making it difficult for the patient to elevate the shoulder. This postoperative complication had no known cause, but it could be iatrogenic or due to structural variation. There is sparse research on possible ways to avoid this complication. Physiotherapy management is critical in improving the patient's functional recovery. The neck and upper extremity functional measure scale and Neurogenic Claudication Outcome Score (NCOS) scale were used for measuring outcomes. The patient also had a two-year history of tingling and numbness in both lower extremities, which was treated conservatively. The difficulties that physiotherapists encounter in managing this uncommon postoperative complication in addition to the lumbar PIVD make it unique. The key to a better prognosis is early detection and management.
