Abstract
OBJECTIVES Expansive open-door laminoplasty (EOLP) is an effective procedure for multilevel cervical spondylotic myelopathy (MCSM). It preserves a higher range of cervical motion than laminectomy with fusion and reserves more posterior elements than laminectomy alone. MCSM with short-segment instability or correctable local kyphosis often requires long-segment decompression and adequate segment fusion. MATERIALS AND METHODS We retrospectively reviewed 20 patients who received EOLP with short-segment posterior lateral mass instrumented fusion at our institution from 2008 to 2011. The follow-up period was at least 36 months. Postoperative functional and radiographic outcomes were collected and analyzed. RESULTS Japanese Orthopedic Association scores improved significantly 36 months after surgery and the average recovery ratio was 85.3 ± 14.7%. Nurick disability scores and neck pain visual analog scale scores considerably decreased 3 years after surgery. No patients had aggravated neck pain or C5 nerve palsy during follow-up. The preservation of range of motion was approximately 60% after 36 months. No implant loosening or laminar collapse was reported on radiographic follow-up. CONCLUSION EOLP with concomitant lateral mass instrumented fusion yields favorable short-term clinical results for MCSM with short segment instability.
