Percutaneous Endoscopic Cervical Discectomy: Surgical Approaches and Postoperative Imaging Changes
Korean Spine Society, 2018Co-Authors: Shu Nakamura, Mitsuto TaguchiAbstract:Study DesignRetrospective clinical study.PurposeThis study investigated the relationship between surgical approaches and surgical outcomes in patients undergoing percutaneous endoscopic Cervical discectomy (PECD), including the reduction in intervertebral disc height and the incidence of Modic changes.Overview of LiteratureThe anterior approach involves partial invasion of the intervertebral disc, with a reported reduction in intervertebral disc height after PECD.MethodsForty-two patients with Cervical Disk Hernia who underwent PECD and magnetic resonance imaging at least 3 months postoperatively were divided into four groups according to the Hernia sites and the surgical approach used: unilateral Hernia treated using the contralateral approach (group C, n=18), unilateral Hernia treated using the ipsilateral approach (group I, n=15), midline Hernia (group M, n=4), and broad and bilateral Hernia (group B, n=5). Modic changes and intervertebral disc height were evaluated.ResultsThe overall incidence of Modic changes was 52.4%: 72.2% in group C, 26.7% in group I, 25.0% in group M, and 80.0% in group B. The reduction in intervertebral disc height was 21.8% across all the patients: 24.5% in group C, 11.0% in group I, 22.8% in group M, and 23.9% in group B.ConclusionsThe incidence of Modic changes and the reduction in intervertebral disc height were lower in the patients treated using the ipsilateral approach than in those treated using the contralateral approach. Traditionally, a contralateral approach has been used for PECD; however, the ipsilateral approach is more appropriate and is therefore recommended

low level laser therapy for patients with Cervical Disk Hernia
Laser therapy, 2012Co-Authors: Hiroshi Takahashi, Ikuko Okuni, Nobuyuki Ushigome, Takashi Harada, Hiroshi Tsuruoka, Toshio Ohshiro, Masayuki Sekiguchi, Yoshiro MusyaAbstract:Background and Aims: In previous studies we have reported the benefits of low level laser therapy (LLLT) for chronic shoulder joint pain, elbow, hand and finger pain, and low back pain. The present study is a report on the effects of LLLT for chronic neck pain. Materials and Methods: Over a 3 year period, 26 rehabilitation department outpatients with chronic neck pain, diagnosed as being caused by Cervical Disk Hernia, underwent treatment applied to the painful area with a 1000 mW semi-conductor laser device delivering at 830 nm in continuous wave, 20.1 J/cm2/point, and three shots were given per session (1 treatment) with twice a week for 4 weeks. Results: 1. A visual analogue scale (VAS) was used to determine the effects of LLLT for chronic pain and after the end of the treatment regimen a significant improvement was observed (p<0.001). 2. After treatment, no significant differences in Cervical spine range of motion were observed. 3. Discussions with the patients revealed that in order to receive continued benefits from treatment, it was important for them to be taught how to avoid postures that would cause them neck pain in everyday life. Conclusion: The present study demonstrates that LLLT was an effective form of treatment for neck and back pain caused by Cervical Disk Hernia, reinforced by postural training.

ct guided percutaneous laser Disk decompression pldd for Cervical Disk Hernia
Radiation Medicine, 2001Co-Authors: Junta Harada, Michiko Dohi, Kunihiko Fukuda, Hiromichi Nakazaki, Tsutomu Koyama, Toshiaki AbeAbstract:OBJECTIVE Percutaneous laser Disk decompression (PLDD) is an effective treatment for bulging or protruding Disk. The aim of this study was to present a method of PLDD for Cervical Disk Hernia under CT guidance and to evaluate the efficacy and safety of this procedure. MATERIALS AND METHODS Seven patients with radiculalgia caused by Cervical Disk Hernia were treated overnight by PLDD. A laser fiber was inserted through an 18 G needle into the target Disk under CT guidance. A Nd-Yag laser (1,064 nm) was used for ablation. A CT scan was obtained every 60 joule (J) at the slice of the target Disk to visualize the vaporized area during the procedure. The Japan Orthopedic Association (JOA) score of Cervical radiculopathy (full score 15) and MacNab criteria were used for assessment of treatment response. RESULTS Puncture of the needle to the target Disk was safely performed under CT guidance. The total dosage of laser ablation ranged from 120 to 500 J (average, 266 J). The overall success rate according to MacNab criteria was good in all cases. No complications were observed in our series. CONCLUSION The CT-guided technique provides safe, accurate PLDD for Cervical Disk Hernia. PLDD for Cervical Disk Hernia shows promise in the management of radiculalgia.

time course of change in Cervical Disk Hernia on mri
Orthopaedics and Traumatology, 1994Co-Authors: Masaaki Morooka, Hiromi Nishizaki, Toshihide Shuto, Yoshihiro KohashiAbstract:We studied the time course of changes in Cervical Disk Hernia using MRI. Cervical Disk Hernia was diagnosed in 1942 patients using MRI, 72 cases of which had MRI performed twice. In 17 cases, we were able to compare MRI changes before and after clinical onset. For the remaining 58 patients, we were able to evaluate the changes seen in the prolapsed Disk.In the latter 58 patients, the period from onset ranged from 24-39.1 months (mean 14.9 months). In 27 cases, the prolapsed Disk reduced in size or disappeared, with one case decreasing in size after only 2.5 months.In these cases, the signal of the prolapsed Disk was low or isointense. In comparison, no change in the size of the prolapsed Disk Hernia was observed in the 17 cases, and one case had no change for at least 2 years. In 12 cases, the size of the Disk Hernia increased.In ten of these 17 cases, who we performed MRI before and after clinical onset, the cases with augumentation of the size of the prolapsed Disk Hernia were observed. The increasing part frequently showed high signal intensity.
