The complications of the Graf stabilization for lumbar disc herniation with posterior instability.: Joo Tae Park, Young Shik Shin, Jeong Ho Yang, Kang Woo Min; Yeungnam Univ J Med. 1998;15(1):164-172. Published online June 30, 1998; DOI: https://doi.org/10.12701/yujm.1998.15.1.164

Abstract PDF: The Graf stabilization has been introduced in treating lumbar spinal disorder associated with posterior instability. This study reviewed some problems of the Graf instrumentation as a soft stabilizer. The purpose of this study is to analyse the problems of the soft stabilization in spinal instability. We reviewed 145 cases which were operative treatment using the Graf instrument for lumbar spinal disorder associated with posterior instability at our department from May, 1991 to Dec, 1995. The mean follow up periods was 29 months ranging from 24 months to 6 years 8 months. Of the 145 cases, 22 cases were showed the problem. The diagnostic method were simple x-ray, flexion-extension lateral stress view and CT scan. Results were as follows : Adjacent segmental instability was 10 cases(6.9%), disc space narrowing was 8 cases(5.5%), screw loosening was 3 cases(2.1%) and breakage of the Graf band was 1 case(0.6%). The problems of the soft stabilization were adjacent segmental instability, disc space narrowing, screw loosening, and breakage of the Graf band. But the rate of adjacent segmental instability and disc space narrowing was lower than other lumbar spinal instrumentation.

Anterior Cervical interbody Fusion with Cervical Spine Locking Plate.: Joo Tae Park, Gil Young Ahn, Young Tae Lee, Myun Whan Ahn; Yeungnam Univ J Med. 1997;14(1):209-219. Published online June 30, 1997; DOI: https://doi.org/10.12701/yujm.1997.14.1.209

Abstract PDF: OBJECTIVES
Anterior approach to achieve arthrodesis of the cervical spine has become a widely accepted and often-used approach since its earliest reports by Bailey and Badgley, Smith and Robinson and Cloward. However, anterior interbody fusion in the presence of the presence of the posterior instability may be complicated by the bone graft dislodgement, kyphotic defomity or nonunion. As an attemp to prevent this undesirable complication, additional methods such as skeletal traction, halo appratus or even posterior fusion has been utilized. Therefore, The cervical spine locking plate(CSLP) with the anterior intervertebral body bone grafting provide immediate cervical stabilization and widely successful in achieving fusion. MATERIAL AND METHODS: This study analysed 14 patients who underwent a single anterior procedure and application of CSLP for the treatment of the cervical spinal disorder. Eleven patients were disc herniations and three patients were traumatic lesion. The average ago of the patient was 47 years and the mean follow up periods was 20 months ranging from 13 to 27 months. RESULTS: Ambulation was started 2nd day after the operation with the aid of the Philadelpia orthoses. Bone union was observed 13 cases on average 12 weeks after operation. The one case was nonunion with plate breakage without clinical symptom. CONCLUSION: Anterior fusion with CSLP are thought to be a safe and valuable method for treating cervical spine disorder.
