퇴행성 요추질환에 대한 편측성 후방 추체간 유합술(1개의 cage를 이용한) 및 척추경 나사못 고정술 = Hemi-Posterior Lumbar Interbody Fusion(by using One Cage) with Transpedicular Screw Fixation for Degenerative Lumbar Diseases

다국어 초록 (Multilingual Abstract)

Objective: The puspose of this study was to determine the efficacy of unilateral posterior lumbar interbody fusion (Hemi-PLIF) by using one cage for the patients with focal type of degenerative lumbar diseases. Materials and Methods: The authors reviewed clinical and radiologic data of 43 patients with focal type of degenerative lumbar diseases who were performed unilateral Hemi-PLIF during the period between November 2000 and June 2003. The operation procedure was unilateral hemi-PLIF using titanium cages with transpedicular screw fixation. Results: The mean follow-up period was 11.2 months. The mean operation time was 197 minutes and the average estimated blood loss was 285mL. The clinical success rate according to Prolo's scale was achieved in 89.3%. of patients and the solid bony fusion was occurred in 96.4%. There were 2 patients of postoperative complications such as superficial infection and screw malposition. Conclusion: This procedure has been found to be an effective and safe procedure with rare complication. To compared with bilateral PLIF, less operation time, less blood loss, more fusion rate is noted.
