The authors present a novel method of the recapping hemilaminoplasty in a retrospective study of patients with spinal surgical disorders. This report describes the surgical technique and the results of hemilaminoplasty using an ultrasonic bone curette. The aim of this study was to examine the safety and effectiveness of the hemilaminoplasty technique with ultrasonic bone curette.
Between April 2003 and July 2011, 33 patients with various spinal diseases (17 spinal tumors, 5 dural arteriovenous fistulas, 3 syringomyelia, 2 sacral perineural cysts, and 2 arachnoid cysts) were treated microsurgically by using an ultrasonic bone curette with scalpel blade and lightweight handpiece. The ultrasonic bone curette was used for division of lamina. After resection of the lesion, the excised lamina was replaced exactly in situ to its original anatomic position with a titanium plate and screw. Additional fusion technique was not required and the device was easy to handle. All patients were observed both neurologically and radiologically by dynamic plain radiographs and computed tomography (CT) scan.
The operation was performed successfully and there were no instrument-related complications such as dural laceration, nerve root injury, and vessels injury. The mean number of resected and restored lamina was 1.7. CT confirmed primary bone fusion in all patients by 12 months after surgery.
The ultrasonic bone curette is a useful instrument for recapping hemilaminoplasty in various spinal surgeries. This method allows anatomical reconstruction of the excised bone to preserve the posterior surrounding tissues.
作者在一项针对脊柱外科疾病患者的回顾性研究中提出了一种新型的半椎板成形术翻修方法。本报告描述了使用超声骨刮匙进行半椎板成形术的手术技术及结果。本研究的目的是检验使用超声骨刮匙的半椎板成形术技术的安全性和有效性。
在2003年4月至2011年7月期间，33例患有各种脊柱疾病的患者（17例脊柱肿瘤、5例硬脊膜动静脉瘘、3例脊髓空洞症、2例骶骨周围神经囊肿和2例蛛网膜囊肿）接受了显微手术治疗，采用带有手术刀刀片和轻型机头的超声骨刮匙。超声骨刮匙用于椎板切开。病变切除后，将切除的椎板用钛板和螺钉精确原位复位至其原始解剖位置。无需额外的融合技术，且该装置易于操作。所有患者均通过动态平片和计算机断层扫描（CT）进行神经学和放射学观察。
手术成功进行，未出现与器械相关的并发症，如硬脊膜撕裂、神经根损伤和血管损伤。切除和复位的椎板平均数量为1.7个。CT证实所有患者在术后12个月时实现了初步骨融合。
超声骨刮匙是各种脊柱手术中半椎板成形术翻修的有用器械。该方法允许对切除的骨进行解剖重建，以保留周围的后部组织。
