摘要
目的
2
探究应用基于O-arm
®
的计算机辅助导航技术在单开门颈椎管扩大成形术中应用的可行性，并对其临床效果进行评价。
方法
2
收集2014年5月至2017年10月，在我科应用基于O-arm
®
的计算机辅助导航技术行单开门颈椎管扩大成形术治疗颈椎管狭窄症的患者26例，男性21例，女性5例；年龄33~76岁，平均59.4岁。根据日本骨科协会(Japanese Orthopaedic Association，JOA)评分(17分法)及其改善率评价术后神经功能改善情况。根据术后6个月复查影像学结果评价椎管扩大情况及门轴侧骨融合情况。

Abstract
Objective
2
To explore the feasibility of computer-assisted navigation technology based on O-arm
®
in unilateral open-door cervical expansive laminoplasty and evaluate its safety and therapeutic effect in patients with cervical spinal stenosis.
Methods
2
From May 2014 to October 2017
26 patients with cervical spinal stenosis
including 21 male and 5 female patients with
a
mean age of 59.4 years (range 33-76 years)
underwent unilateral open-door cervical expansive laminoplasty in our department with computer-assisted navigation technology based on O-arm
®
. The postoperative neurological improvement of the patients was evaluated by assessing the Japanese Orthopedic Association (JOA) score (17 points) and the improvement rate. All the patients underwent imaging examinations at 6 months after the operation to assess postoperative spinal canal enlargement and bone fusion on the hinge side.
Results
2
The mean operation time was 162.2±24.0 min in these cases with
a
mean intraoperative blood loss of 282.7±117.0 mL; no complications occurred during the operation. All the patients were followed up for 6.0-46.4 months (mean 22.8±10.5 months). The mean JOA score of the patients before the operation was 8.1±2.7
which increased to 13.4±2.7 at the final follow-up. All the patients showed significant improvements of the clinical symptoms (
P
<
0.05) with
a
mean improvement rate of (58.2±30.4)%. At 6 months after operation
all the patients
except for 1 patient who was lost to the follow-up
showed satisfactory enlargement of the spinal canal and bony fusion on the hinge side without recurrence of cervical stenosis or neurofunction deterioration.
Conclusion
2
Unilateral open-door cervical expansive laminoplasty with computer-assisted navigation technology based on O-arm
®
is safe and feasible and can achieve satisfactory therapeutic effect for treatment of cervical spinal stenosis.
