Multilevel Cervical Spondylotic Myelopathy

ABSTRACT Objective: To report two cases of multilevel cervical spondylotic myelopathy with monosegmental instability, in which we performed a minimally invasive microsurgical transmuscular approach with tubular retractors to create a single-door plate laminoplasty combined with fixation of the unstable segment with lateral mass screws. Methods: The surgical procedures were performed by the senior author. In both patients, the follow-up was performed using the Oswestry Disability Index (ODI), the Visual Analogue Scale for neck and radicular pain (radVAS, neckVAS), the Neck Disability Index (NDI) and the Short Form 36 (SF-36), in the preoperative (preop) and postoperative (postop) periods, and at 1, 3, 6, 12, 18 and 24 months. A radiological evaluation also was performed, which included AP, lateral and flexion-extension films at 6, 12 and 24 months and CT-scan at 12 months. Results: Case 1 - preop ODI: 40%, 24 months postop ODI: 4%; preop radVAS: 7, 24 months radVAS: 0; preop neckVAS: 8, postop 24 months neckVAS: 0; preopNDI: 43%, 24 months PostopNDI: 8%; SF-36 - preop Physical Functioning (PF): 40, preop Vitality (VT): 40, preop Emotional role functioning (RE): 33.3, Bodily pain (BP): 51, General Health (GH): 57, Social Functioning (SF): 75; postop PF: 95, VT: 95, RE: 100, BP: 74, GH: 87, SF: 100. Case 2 - preopODI: 46%, 24 months postopODI: 10%; preop radVAS: 7, 24m radVAS: 0; preop neckVAS: 9, postop 24 months neckVAS: 0; preopNDI: 56%, 24 months PostopNDI: 15%; SF-36 - preop PF: 39, VT: 45, RE: 33.3, BP: 50, GH: 49, SF: 70; postop PF: 90, VT: 100, RE: 100, BP: 82, GH: 87, SF: 100. No complications, cervical instability or signs of failed surgery were found trough and at final follow-up at 24 months. We found significant clinical improvement in both patients. Conclusions: Minimally invasive cervical laminoplasty combined with lateral mass screw fixation for the unstable segment is a useful technique in cases with multilevel cervical spondylotic myelopathy associated with monosegmental instability. Additional comparative studies are needed to establish its efficacy.

Objective: There is controversy in surgical management of cervical spondylotic myelopathy (CSM); a few group encourage only laminectomy or laminoplasty while the others emphasize on lateral mass fixation along with laminectomy. Cervical lordosis is an important factor for maintaining posture neck and preventing postoperative axial neck pain. Literature has reported that cervical lordosis less than -20 degrees is often responsible for neck pain. The purpose of this study was to evaluate clinical outcome and radiological parameters after posterior cervical laminectomy and fixation in CSM. Material and Methods: This retrospective study included 37 patients operated with posterior cervical decompression and lateral mass screw fixation with minimum two-year follow-up. All patients were operated for CSM. All were operated by a single surgeon and followed up at six weeks, twelve weeks, six months, one year and yearly afterwards. Clinical outcome and radiological parameters were analyzed for clinical improvement [European Myelopathy Score (EMS)] and cervical lordotic angle. Results: Average age 68±8.3 years. The cervical lordotic angle of -23.02±4.19 degrees was maintained in patients operated with lateral mass screw fixations along with laminectomy at final follow-up. The EMS and VAS score showed significant improvement postoperatively from 15.7 to 13.6 (p<0.05) and 8.1 to 1.5 (p<0.05), respectively. Three patients had postoperative C5 palsy that recovered completely within three months. Two patients expired within a few months after surgery due to acute myocardial infarction and respiratory arrest, respectively. There were three patients who had postoperative C5 palsy, which recovered completely within three months postoperatively. There was no permanent postoperative neurological deficit noticed in the series. Conclusion: Posterior cervical lateral mass screw fixation for CSM gives satisfactory clinical outcome and maintains cervical lordosis. Lateral mass fixation with

Abstract BACKGROUND: Sectioning of the C2 nerve root allows for direct visualization of the C1-2 joint and may facilitate arthrodesis. OBJECTIVE: To determine the clinical and functional consequences of C2 nerve root sectioning during placement of C1 lateral mass screws. METHODS: All patients undergoing C1 lateral mass screw fixation were included in this prospective study. A standard questionnaire was used to determine the severity of occipital numbness/pain and its effect on quality of life (QOL). Domains of the neck disability index were used to assess the disability related to C2 symptoms. RESULTS: A total of 28 patients were included (C2 transection, 8; C2 preservation, 20). A trend of decreased blood loss and length of surgery was observed in the C2 transection cohort. Occipital numbness was reported by 4 (50.0%) patients after C2 transection. Occipital neuralgia was reported by 7 (35.0%) patients with C2 preservation. None of the patients with numbness after C2 transection reported being “bothered” by it. All patients with occipital neuralgia after C2 sparing reported being “bothered” by it, and 57.1% reported a moderate to severe effect on QOL. The use of medication was reported by 5 (71.4%) patients with neuralgia vs none with numbness. Mean disability was significantly higher with neuralgia vs numbness (P = .016). CONCLUSION: C2 nerve root transection is associated with increased occipital numbness but this has no effect on patient-reported outcomes and QOL. C2 nerve root preservation can be associated with occipital neuralgia, which has a negative impact on patient disability and QOL. C2 nerve root transection has no negative consequences during C1-2 stabilization.
