  • Comparison of microendoscopic Discectomy System and open anterior approach for unstable odontoid fracture with cannulated screw
    Acta Orthopaedica Belgica, 2014
    Co-Authors: Bin Lin
    Abstract:

    Purpose: The purpose of this study was to determine the safety, effective of the Microendoscopic Discectomy System anterior screw fixation compared with the open anterior approach.Methods: Thirtytwo patients, 25 male and 7 female, 15 cases were treated under Microendoscopic Discectomy System anterior screw fixation and 17 cases with Open Anterior Approach. The operating time, blood loss, complication, healing rate of  fracture were compared.Results: In MED Group, mean operating time and blood loss were less than those in Open Group (P < 0.05). All the patients obtained bony union and cervical rang of motion in the two groups had no statistical diference (P > 0.05). Three patients complained transient dysphagia occurred in the Open Group.Conclusions: Microendoscopic Discectomy System technique for odontoid screw fixation provides a minimally invasive, safe and reliable procedure in contrast to open approaches

  • Comparison of microendoscopic Discectomy System and anterior open approach in treatment of unstable odontoid fracture with cannulated screw internal fixation.
    Acta orthopaedica Belgica, 2014
    Co-Authors: Bin Lin, Wenbin Zhang, Wenqing Yang
    Abstract:

    This study intended to investigate the safety and efficacy of microendoscopic Discectomy System compared with anterior open approach in the treatment of odontoid fracture with cannulated screw internal fiation. Thirty-two patients (25 male and 7 female) were enrolled and randomly assigned to different treatments. 15 patients were treated with microendoscopic Discectomy System (Group MED) and 17 patients were treated with anterior open approach (Group AOA). The operating time, volume of blood loss, occurrence of complications, and fracture healing rate were compared. In Group MED, the mean operating time and blood loss volume were significant lower than those in Group AOA (P 0.05). Three patients in Group AOA complained of transient dysphagia. We concluded that microendoscopic Discectomy System for odontoid fracture treatment with cannulated screw is a safe, reliable and minimal invasive procedure compared with traditional open surgery.

  • The causes and solutions of re-operative treatment after operation with micro-endoscopic Discectomy System
    China Journal of Orthopaedics and Traumatology, 2007
    Co-Authors: Tang Fu-y
    Abstract:

    Objective:To explore the causes and solutions of re-operative treatment after operation with micro-endoscopic Discectomy (MED) System and determine decompression principle of micro-endoscopic Discectomy System. Methods: Elven patients who needed re-operative after first operation of MED included 4 male and 7 female, ranging in age from 28 to 52 years (mean 34.5 years). Further surgical methods were involving MED in 2 cases, windows decompression in 4, circular decompression in 4 and half laminectomy excision in 1. Retrospective analysis of the patients was made.Results: The reason for the re-operation was the wrong positioning of surgical operations in 2 cases, dissociate nucleus missing in 1, nucleus further away in 1, detained again highlight in 2, only removing nucleus but no deal with lateral recess narrow in 5. After an average of 13 months (8 to 20 months) follow-up, assessed by the Nakai standard, the result was excellent in 7 cases, good in 3 cases, fair in 1 case.Conclusion: MED surgery should follow the principle that decompression should base on nerve center root. Recurrence after surgery is related to improper indications choice, positioning errors and surgical techniques, but satisfactory efficacy can be achieved through further surgery.

  • Endoscopic foraminotomy using a microendoscopic Discectomy System in cadaveric specimens
    Neurosurgical Focus, 1998
    Co-Authors: Alberto C. Cardoso, Richard G. Fessler
    Abstract:

    Although the anterior approach is more commonly performed for the treatment of cervical disc disease, the posterior approach has distinct advantages in selected cases of foraminal stenosis and posterolateral disc herniation. The authors performed cervical key hole foraminotomies using a microendoscopic Discectomy (MED) System in four cadaveric cervical spine specimens to evaluate this minimally invasive surgical approach for cervical disc diseases. The amount of bone decompression achieved by using the MED System was compared with that achieved by using the open foraminotomy procedure in each cadaveric specimen. Three noncontiguous cervical nerve roots were selected between C-3 and C-8 in each specimen and were decompressed using the MED System on one side and using the open foraminotomy procedure on the contralateral side. Postoperative computerized tomography (CT) myelography showed that adequate bone decompression was achieved by using either the MED or open procedure in all specimens. Postoperatively, open dissection was performed to confirm and compare the amount of decompression in both the MED and open procedures. The laminotomy size (vertical and transverse diameter), the length of decompressed nerve root, and the proportion of removed facet joint were measured on every operative level. The average vertical diameter of laminotomy area and the percentage of facet removed were significantly greater in the MED procedure than the open procedure (p < 0.05). The transverse diameter of the laminotomy area and the average decompressed root length were not significantly different between MED and open surgery. The authors conclude that endoscopic cervical foraminotomy using the MED System is a feasible procedure and may be clinically applicable in the treatment of foraminal stenosis and laterally located cervical disc herniation.

  • Minimally invasive surgery for osteoid osteoma of the cervical spine using microendoscopic Discectomy System.
    Asian spine journal, 2013
    Co-Authors: Yukako Nakamura, Shoji Yabuki, Shinichi Kikuchi, Shinichi Konno
    Abstract:

    We report herein the case of an 18-year-old man who underwent endoscopic resection for an osteoid osteoma in the seventh cervical facet joint. The patient had experienced right neck pain for approximately one year, but no neurological abnormalities were noted. Cervical magnetic resonance imaging suggested an osteoid osteoma in the superior articular process of the seventh cervical vertebra. The tumor was resected microendoscopically. Operative time was 1 hour 29 minutes, and blood loss was 5 mL. During the two years since surgery, the patient has remained pain free with no cervical spine instability. We thus propose microendoscopic surgery for osteoid osteoma developing in a posterior element of the cervical spine is a potentially effective operative procedure.

  • Posterior Vertebral Route Approach Microendoscopic for the Treatment of Lumbar Degenerative Spinal Stenosis
    The Orthopedic Journal of China, 2003
    Co-Authors: Pu Xing-ping
    Abstract:

    Objective: To investigate clinical application of posterior spinal approach microendoscopic for the treatment of lumbar degenerative spinal stenosis. Methods: From Feb. 2000 to Dec. 2001, 87 cases of lumbar degenerative spinal stenosis were treated by microendoscopic Discectomy System (MED) with posterior vertebral route approach. The choice of case, operative procedures and skill were given a discussion. Results: All patients had no postoperative complication, 82 cases with a 10～32 months follow up, the rate of excellent and good was 92.7% according to Nakano evaluation standard. Conclusions: Lumbar degenerative spinal stenosis can be treated by MED procedures. Strictly selected indication, completely decompression and experienced operative skill of MED are the key to successful and effective rate of treatment.
