Canal Expansive Laminoplasty in the Management of Cervical Spondylotic Myelopathy


     Background: Cervical spondylotic myelopathy is often progressive and leads to motor and sensory impairments in the arms and legs. Canal expansive laminoplasty was initially described in Japan as an alternative to the traditional laminectomy approach. The results of this approach have not previously been described in the Israeli population.

    Objectives: To describe the technique of CEL[1] and present our clinical results in the management of patients with CSM[2] due to multilevel compressive disease.

    Methods: All patients undergoing CEL during the period 1984–2000 were identified. Of these, 24 of 25 patients had complete clinical information. Mean follow-up was 18 months (range 4–48). Mean age was 60 years (range 45–72). One patient underwent CEL at three levels, 22 at four to five levels and 1 patient at six levels The primary outcome measure was improvement in spinal cord function (according to the Nurick classification).

    Results: Twenty-three (96%) of the patients experienced relief of their symptoms. Of these, 11 patients showed improvement in their Nurick grade, 12 patients were unchanged and one had worsening. Intraoperative complications (epidural bleeding and dural tear) occurred in six patients. Two patients developed a late kyphosis.

    Conclusions: Our treatment of choice for multilevel CSM is canal expansive laminoplasty as initially described by Hirabayashi. It provides the ability for posterior surgical decompression without compromising the mechanical stability of the spine. This approach has the benefit of not requiring internal fixation and fusion. Our clinical outcome and surgical complication rate is comparable to other studies in the literature.
