Endogenous-lesioned cervical disc herniation: a retrospective review of 9 cases.
The purpose of this study was to analyze the pathogenic mechanisms, clinical presentation, and surgical treatment of cervical disc herniation without external trauma. Between 2004 and 2008, 9 patients with cervical disc herniation and no antecedent history of trauma were diagnosed with cervical disc herniation and underwent surgical decompression. Pathogenic mechanisms, clinical presentation, surgical treatment, and prognosis were analyzed retrospectively. In 6 patients, herniation resulted from excessive neck motion rather than from external trauma. An injury from this source is termed an endogenous-lesioned injury. Patients exhibited neurologic symptoms of compression of the cervical spinal cord or nerve roots. In the other 3 patients, no clear cause for the herniation was recorded, but all patients had a desk job with long periods of head-down neck flexion posture. After surgery, all patients experienced a reduction in their symptoms and an uneventful recovery. Cervical disc herniation can occur in the absence of trauma. Surgical decompression is effective at reducing symptoms in these patients, similar to other patients with cervical disc herniation. Surgical treatment may be considered for this disorder when the herniation becomes symptomatic.
