The cervical somatosensory evoked potential after median nerve stimulation was recorded in 14 patients with cervical spondylosis with radiculopathy and, in 10 cases, myelopathy. Four patients had normal potentials, five showed delayed potentials, and in five others no potential could be seen.

BACKGROUND AND OBJECTIVES Surgical treatment of cervical radiculopathy with or without myelopathy is a controversy issue, although anterior discectomy is the most common form of treatment. METHOD We present the evaluation of the arthrodesis' rate and cervical alignment in 48 patients with cervical degenerative disease (CDD) submitted to anterior cervical discectomy with interposition of polym...

Anterior cervical discectomy and fusion(ACDF) is a surgical treatment for cervical radiculopathy and myelopathy. Though this is a common surgery, spinal epidural hematomas occur rarely and an immediate treatment decision and surgical decompression are required in this situation. In this report, we discuss the proper treatment of spinal epidural hematoma after ACDF.

The two types of upper limb somatosensory evoked potential abnormality observed in nine patients with syringomyelia were reduced amplitude or absent cervical potentials and an abnormal central conduction time. Although this pattern of abnormalities resembles that observed in other intrinsic spinal cord lesions, it differs from peripheral nerve diseases and cervical radiculopathy in which the ce...

Pancoast tumor accounts for 3%-5% of all non-small cell lung carcinomas. This tumor has a distinct clinical presentation through local invasion and the resulting clinical entity called Pancoast syndrome. This syndrome includes severe shoulder pain, arm pain, and Horner’s syndrome andatrophy of forearm and hand muscles. The differential diagnosis of arm and shoulder pain is extensive. Thoracic o...

OBJECTIVE Diagnostic selective nerve root injection (SNI) results were analyzed in 101 patients who underwent lumbar or cervical decompression for radiculopathy and compared to surgical outcome 1 year postoperatively. A comparison of surgical outcomes was also examined between magnetic resonance imaging (MRI) and SNI results. RESULTS Of the 101 patients, 91 (90%) had positive and 10 had negat...

Cervical myelopathy and radiculopathy are common pathologies that often improve with spinal decompression and fusion. Postoperative complications include pseudarthrosis, which can be challenging to diagnose and manage. We reviewed the literature with regard to risk factors, diagnosis, controversies, and management of cervical pseudarthrosis.
