        Incidence and Characteristics of Clinical L5–S1 Adjacent Segment Degeneration after L5 Floating Lumbar Fusion: A Multicenter Study

        Takegami Norihiko,Akeda Koji,Yamada Junichi,Imanishi Takao,Fujiwara Tatsuhiko,Kondo Tetsushi,Takegami Kenji,Sudo Akihiro 대한척추외과학회 2023 Asian Spine Journal Vol.17 No.1

        Study Design: Retrospective study.Purpose: This study aimed to evaluate the incidence, characteristics, and risk factors for clinical L5–S1 adjacent segment degeneration (ASD) after L5 floating lumbar fusion.Overview of Literature: ASD is known to occur after lumbar spine fusion at a certain frequency. Several studies on radiological L5– S1 ASD have been reported. However, there are only a few studies on L5–S1 ASD with clinical symptoms, including back pain and/or radiculopathy.Methods: In total, 306 patients who received L5 floating lumbar fusion were included in this study. Clinical L5–S1 ASD was defined as newly developed radiculopathy in relation to the L5–S1 segment. Patients’ medical records and imaging data were retrospectively analyzed. The risk factors for clinical ASD were assessed by an inverse probability of treatment weighting-adjusted logistic regression analysis.Results: Clinical L5–S1 ASD occurred in 17 patients (5.6%). The mean onset time of L5–S1 ASD was 12.9±7.5 months after the primary surgery. Among these patients, 10 (58.8%) presented with clinical L5–S1 ASD within 12 months. Reoperation was performed in three patients (1.0%). The severity of L5–S1 disk degeneration did not affect the occurrence of L5–S1 ASD. Logistic regression analysis showed that the number of fusion levels was a significant risk factor for clinical L5–S1 ASD.Conclusions: The incidence and characteristics of clinical L5–S1 ASD after L5 floating lumbar fusion were retrospectively investigated. This study established that the number of fusion levels was a significant candidate factor for clinical L5–S1 ASD. Careful clinical follow-up is deemed necessary after L5 floating lumbar fusion surgery, especially for patients who received multiple-level fusions.

        Intradiscal Injection of Autologous Platelet-Rich Plasma Releasate to Treat Discogenic Low Back Pain: A Preliminary Clinical Trial

        Koji Akeda,Kohshi Ohishi,Koichi Masuda,Won C. Bae,Norihiko Takegami,Junichi Yamada,Tomoki Nakamura,Toshihiko Sakakibara,Yuichi Kasai,Akihiro Sudo 대한척추외과학회 2017 Asian Spine Journal Vol.11 No.3

        Study Design: Preliminary clinical trial. Purpose: To determine the safety and initial efficacy of intradiscal injection of autologous platelet-rich plasma (PRP) releasate in patients with discogenic low back pain. Overview of Literature: PRP, which is comprised of autologous growth factors and cytokines, has been widely used in the clinical setting for tissue regeneration and repair. PRP has been shown in vitro and in vivo to potentially stimulate intervertebral disc matrix metabolism. Methods: Inclusion criteria for this study included chronic low back pain without leg pain for more than 3 months; one or more lumbar discs (L3/L4 to L5/S1) with evidence of degeneration, as indicated via magnetic resonance imaging (MRI); and at least one symptomatic disc, confirmed using standardized provocative discography. PRP releasate, isolated from clotted PRP, was injected into the center of the nucleus pulposus. Outcome measures included the use of a visual analog scale (VAS) and the Roland-Morris Disability Questionnaire (RDQ), as well as X-ray and MRI (T2-quantification). Results: Data were analyzed from 14 patients (8 men and 6 women; mean age, 33.8 years). The average follow-up period was 10 months. Following treatment, no patient experienced adverse events or significant narrowing of disc height. The mean pain scores before treatment (VAS, 7.5±1.3; RDQ, 12.6±4.1) were significantly decreased at one month, and this was generally sustained throughout the observation period (6 months after treatment: VAS, 3.2±2.4, RDQ; 3.6±4.5 and 12 months: VAS, 2.9±2.8; RDQ, 2.8±3.9; p <0.01, respectively). The mean T2 values did not significantly change after treatment. Conclusions: We demonstrated that intradiscal injection of autologous PRP releasate in patients with low back pain was safe, with no adverse events observed during follow-up. Future randomized controlled clinical studies should be performed to systematically evaluate the effects of this therapy.
