Cervical laminoplasty to enlarge the spinal canal in multilevel ossification of the posterior longitudinal ligament with myelopathy.

We studied 23 patients with severe myeloradiculopathy involving multiple (more than three) levels of ossification of the posterior longitudinal ligament (OPLL) of the cervical spine, who were treated with laminoplasty to enlarge the spinal canal. The resected spinous processes were used as bone grafts to support the opened laminae. These patients were analyzed pre- and postoperatively with a neurological evaluation according to the Japanese Orthopedic Association (JOA) score system for cervical myelopathy. Follow-up was from 2.0 to 5.3 years with an average of 31.5 months. The results were compared with those in 31 patients with the same degree (multilevel) of OPLL who had been operated upon previously by laminectomy (14 cases) or anterior resection (17 cases). Postoperative neurological recovery by improvement ratio of the JOA score was observed in 81.2% of those who had undergone expansive laminoplasty, in 72.4% of those with laminectomy, and in 63.6% of those with anterior decompression. We concluded that expansive laminoplasty is a safer procedure with fewer complications. Stability is achieved by fixing the expanded laminae permanently with a bone graft. The neurological recovery following our technique of laminoplasty and fusion appears to be superior to that with laminectomy or anterior decompression.

Postoperative outcome of lumbar spinal canal stenosis after fenestration: correlation with changes in intradural and extradural tube on magnetic resonance imaging.

PURPOSE: To evaluate the serial changes in clinical results and the intradural and extradural spaces on magnetic resonance imaging (MRI) after bilateral fenestration in 48 patients with lumbar spinal canal stenosis (LSCS). METHODS: A prospective interventional study was performed to study the clinical results, magnetic resonance imaging scans among patients who were followed up for more than 3 years. RESULTS: All patients showed improvement in clinical symptoms after operation, but clinical results deteriorated in 9 (19%) patients. Postoperative MRI scans showed that poor dural tube expansion, grouping of the cauda equina, and decrease in the cross-sectional area of the dural tube were factors associated with poor outcomes. The cross-sectional area of the dural tube and images of the cauda equina observed by MRI, before and after fenestration and during follow-up, reflected changes in clinical symptoms involving decompressed segments. CONCLUSION: Serial changes in the cross-sectional area of the dural tube and images of the cauda equina observed preoperatively, postoperatively, and on follow-up by MRI may be useful when evaluating patients' condition before and after operation. It is also useful for predicting outcomes.

Intradural extramedullary epidermoid cyst of the spinal canal: report of one case.

A 9-year-old girl developed a progressive unsteady gait for one month. Hyperactive reflexes of the four extremities and a spasticity of the lower extremities were found. Bilateral Babinski responses were elicited. An intradural extramedullary mass of upper thoracic spinal cord was demonstrated using magnetic resonance imaging and was confirmed as an intradural extramedullary epidermoid cyst at surgery. This epidermoid cyst was from congenital origin. No congenital anomalies such as spina bifida or dermal sinus were associated. The epidemiology, clinical features, radiology, surgical treatment and pathology of this benign tumor are discussed.
