Posterolateral microdisectomy for cervical monoradiculopathy caused by posterolateral soft cervical disc sequestration.

Abstract：

:The controversy over whether to use a posterior or anterior approach for surgical treatment of soft cervical discs is still largely unsettled. However, although the posterior approach may be underutilized, it has distinct advantages when there are specific indications. Out of a large pool of cases, 53 patients presented with acute monoradiculopathy caused by soft cervical disc herniation. In 36 of these, the disc was sequestered (nonconfined) and was posterolateral to the disc space as seen on computerized tomography-myelography. Distinct motor weakness was a common clinical finding in all 36 cases. These patients were treated by using a 2- to 3-cm skin incision for the posterolateral microsurgical approach. The extent of the lateral facetectomy depended upon the relationship between the nerve root and the disc. All fragments were lateral to the dural sac and were sequestered through the anulus fibrosus and the posterior longitudinal ligament. Sequestrations were removed under direct microscopic vision, but the disc space was not entered. Pain relief and motor-power improvement in the affected radicular distribution were immediate in all patients. Sensory deficit and residual motor loss improved dramatically with normalization at approximately 6 months. No complications occurred and the mean hospital stay was 2 days. The follow-up period varied from 4 to 42 months with a mean of 26 months. Thus far, there have been no recurrences or other associated complications. By using strict selection criteria and a microsurgical posterolateral approach with removal of the sequestered disc fragment, excellent results with normalization of the monoradiculopathy can be obtained. The ease of this technique, low risk, minimal complications, and excellent results make it an attractive alternative to the anterior approach. The clinical presentations, specific indications, surgical technique, and clinical results are discussed; and a prototype of a small cervical self-retaining retractor is described.
