    Co-Authors: Jiang Liang, Lv Yang, Liu, Xiao Guang, Ma, Qing Jun, Wei Feng, Dang, Geng Ting, Liu, Zhong Jun
    Abstract:

    Study Design. A retrospective study of a new classification and surgical approach of cervical dumbbell tumors. Objective. To evaluate PUTH classification. Summary of Background Data. The high recurrence rate and postoperative deformity are unsolved problems. Asazuma's landmark classification could not cover all cases and could not provide clear suggestion for the surgical approach. The ideal classification should be comprehensive, easily understood and of practical value. Methods. PUTH classification for cervical dumbbell tumors includes 7 categories ( types 1-7) and 2 foraminal modifiers. Posterior approach is appropriate for type 1, 2 and 5 tumors, anterior and anterolateral approach is an ideal choice for type 4 and 6 tumors. Type 7 tumors need combined anterior and posterior approach. Results. Forty-four consecutive patients with cervical dumbbell tumor were surgically treated. The pathology included schwannoma in 31 cases, neurofibroma in 9 and ganglioneuroma in 4. Based on PUTH classification, type 3 was diagnosed in 13 cases, type 5 in 17, type 6 in 8, and type 7 in 6. Tumors were unilateral in 41 cases, and bilateral in 3 cases. Five were tumor revision cases. Thirty patients underwent posterior approach, 7 had anterior approach, 1 had anterolateral approach, and 6 had combined approach. Gross total resection was achieved in all the patients. Tumors involved nerve roots were transected in 12 cases. Single vertebral artery was ligated in 3. The complications included cerebrospinal fluid leakage in 18 cases, Esophagus Injury in 1, Horner syndrome in 1, dysphagia in 2, dyspnea in 1 and deep infection in 1. Thirty-six cases (81.1%) had an average 61-month follow-up. Recurrence was found in only one case (2.8%). Conclusion. PUTH classification covers all tumor types and is easier to remember. It is practical and useful for determining the surgical approach. The recurrence rate decreases significantly after radial tumor resection. Revision surgeries are associated with more complications.Clinical NeurologyOrthopedicsSCI(E)PubMed12ARTICLE121307-13143

  • Curative efficacy analysis of anterior cervical decompression combined with zero-profile interbody fusion system for cervical spondylotic myelopathy
    Journal of Xinxiang Medical University, 2014
    Co-Authors: Liu Jun-lian
    Abstract:

    Objective To analyze the clinical efficacy of anterior cervical decompression combined with zero-profile interbody fusion system( Zero-P) for cervical spondylotic myelopathy. Methods A total of 41 patients with cervical spondylotic myelopathy who underwent anterior cervical decompression combined with Zero-P interbody fusion and internal fixation were selected,including 39 patients with monosegmental and 2 patients with bisegmental disc disease. A total of 43 Zero-Ps were implanted,the number of Zero-Ps implanted in the segment C3 /4,C4 /5,C5 /6,C6 /7 and C7 / T1 was 5,11,17,8 and 2 respectively. Japan Orthopedic Association( JOA) score and Odom grade standard were used to evaluated surgical treatment efficacy, and the postoperative complications and bone graft fusion were observed. Results The average of operation duration was( 73. 7 ±11. 6) min and intraoperative blood loss was( 60. 0 ±5. 1) mL. There was no dysphagia,wound infections,nerve Injury,trachea and Esophagus Injury after operation. The follow-up average time was( 17. 3 ± 3. 4) months and there was no fixation-related complications such as fixator loosening and breakage,vertebral instability,vertebral body heigh during follow-up time. The spinal cord function improved significantly. The JOA score improved significantly( P 0. 05),from 8. 76 ± 1. 15 before operation to 12. 16 ± 1. 07 of one month follow-up and 14. 37 ± 1. 21 of the last follow-up time. According to Odom standard,excellent outcome was seen in 32 cases,good in 7 cases,fair in 2 cases. The excellent and good rate was 95. 1% and the bone graft fusion rate was 100. 0%. Conclusion The clinical efficacy of anterior cervical decompression combined with ZeroP for cervical spondylotic myelopathy is satisfactory and reliable. Zero-P has easy operation,reliable integration,fewer complication and other advantages. It is an ideal internal fixation method.
