BACKGROUND: Paraspinal muscle spasm caused by pain from a lumbar degenerative disc is frequently investigated in patients with low back pain. Radiofrequency ablation (RFA) surgery could alleviate paraspinal muscle spasms. OBJECTIVES: We performed RFA surgery on the high-intensity zone (HIZ) and hypersensitive sinuvertebral and basivertebral nerves to evaluate its outcome. The paravertebral muscle cross-sectional area (CSA) was measured on magnetic resonance imaging (MRI) before and after surgery to evaluate the effect of RFA surgery on the paravertebral muscle. STUDY DESIGN: Prospective cohort study. SETTING: A single spine surgery center. METHODS: A comparative study was performed on 2 different uniportal spinal endoscopic surgery groups; 23 patients who underwent RFA surgery for chronic discogenic back pain and 45 patients who underwent posterior decompression surgery for lumbar spinal stenosis with 12 months of follow-up. Paravertebral muscle cross-sectional area, Schiza grade, Modic type, and HIZ size were measured on pre- and post-operative MRI. An endoscopic video review was performed to evaluate the presence of intraoperative twitching and grade the degree of epidural neovascularization and adhesion. Visual analog scale VAS, modified Oswestry Disability Index, ODI and MacNab’s criteria were evaluated for outcome measures. RESULTS: Intraoperative endoscopic video evaluation showed neovascularization and adhesion adjacent to the disc and pedicle. In the RFA surgery group, there were 7 patients (30.43%) with grade 2 and 16 (69.57%) with grade 3 neovascularization; intraoperative twitching was observed in 19 out of 23 patients (82.61%). After performing an RFA on the sinuvertebral and basivertebral nerves for the treatment of discogenic back pain, the results showed significant improvement in pain and disability scores. The mean CSA of the paraspinal muscle in the RFA surgery group was significantly increased after surgery at the L4–L5 and L5–S1 levels (L4–L5: 3901 ± 1096.7 mm² to 4167 ± 1052.1 mm², P = 0.000; L5-S1: 3059 ± 968.5 mm² to 3323 ± 1046.2 mm², P = 0.000) compared to preoperative CSA. LIMITATIONS: This study was limited by its small sample size. CONCLUSION: Hypersensitive sinuvertebral and basivertebral nerves are strongly associated with epidural neovascularization with adhesion and the pathological pain pathway in degenerative disc disease. Epidural neovascularization with adhesion reflects aberrant neurological connections, which are associated with reflex inhibitory mechanisms of the multifidus muscle, which induces spasm. RFA treatment of the region of epidural neovascularization with adhesion effectively treated chronic discogenic back pain and could induce paraspinal muscle spasm release.

Abstract Background The purpose of the study is to investigate the correlation between upper lumbar disc herniation (ULDH) and multifidus muscle degeneration via the comparison of width, the cross-sectional area and degree of fatty infiltration of the lumbar multifidus muscle. Methods Using the axial T2-weighted images of magnetic resonance imaging as an assessment tool, we retrospectively investigated 132 patients with ULDH and 132 healthy individuals. The total muscle cross-sectional area (TMCSA) and the pure muscle cross-sectional area (PMCSA) of the multifidus muscle at the L1/2, L2/3, and L3/4 intervertebral disc levels were measured respectively, and in the meantime, the average multifidus muscle width (AMMW) and degree of fatty infiltration of bilateral multifidus muscle were evaluated. The resulting data were analyzed to determine the presence/absence of statistical significance between the study and control groups. Multivariate logistical regression analyses were used to evaluate the correlation between ULDH and multifidus degeneration. Results The results of the analysis of the two groups showed that there were statistically significant differences (p < 0.05) between TMCSA, PMCSA, AMMW and degree of fatty infiltration. The multivariate logistic regression analysis indicated that the TMCSA, PMCSA, AMMW and the degree of fatty infiltration of multifidus muscle were correlated with ULDH, and the differences were statistically significant (P < 0.05). Conclusions A correlation could exist between multifidus muscles degeneration and ULDH, that may be a process of mutual influence and interaction. Lumbar muscle strengthening training could prevent and improve muscle atrophy and degeneration.

Abstract Background: Impairments in the lumbar multifidus muscle such as reduced muscle thickness and fat infiltrations are evident in individuals with low back pain. Lumbar stabilization exercises (LSE) with real-time ultrasound imaging (RUSI) biofeedback has been reported to improve preferential activation of as well as retention in the ability to activate of the lumbar multifidus muscle, thus enhancing recovery. However, the effects of using this treatment approach in individuals with nonspecific chronic low back pain (NCLBP) seemed not to have widely reported. The purpose of this study is, therefore, to investigate the effects of LSE with RUSI biofeedback on lumbar multifidus muscle cross-sectional area in individuals with NCLBP patients. Method: This study is a prospective, single-center, assessor-blind three-arm, randomized controlled to be conducted at National Orthopedic Hospital, Kano State, Nigeria. Ninety-one individuals with NCLBP will be randomly assigned into one of the three treatment groups of equal sample size (n = 30); LSE group, LSE with RUSI biofeedback group, or control (minimal intervention). The participants in the LSE and LSE with RUSI biofeedback group will also receive the same intervention as the control group. All participants will receive treatment twice weekly for 8 weeks. The primary outcome will be lumbar multifidus muscles cross-sectional area while the secondary outcomes will be pain, functional disability and quality of life. All outcomes will be assessed at baseline, and at 8 weeks and 3 months post-intervention.Discussion: The outcome of the study may support the evidence for the effectiveness of LSE with RUSI biofeedback in the rehabilitation of individuals with NCLBP. It may also provide a rationale for the physiotherapists to make use of diagnostic ultrasound as a feedback mechanism in enhancing the performance and retention of LSE program as well as monitoring the patient’s recovery.Trial registration: Pan African Clinical Trials Registry, (PACTR201801002980602), Registered on 16 January 2018.
