“…25 Our finding that neck disability could be associated with fatty infiltration of deep posterior paraspinal muscles according to the severity of OPLL, is consistent with these previous results. 25,41 Clinical manifestations, paraspinal muscle degeneration, and OPLL morphology may have a complex interaction with each other and lead to a cycle of repeated neck-associated clinical problems. A better understanding of the mechanisms underlying the development of clinical manifestations owing to paraspinal muscle degeneration could contribute toward better clinical management of patients with cervical OPLL.…”

Study Design: A retrospective observational study. Objective: To clarify the association of the paraspinal muscle area and composition with clinical features in patients with cervical ossification of the posterior longitudinal ligament (OPLL). Methods: Consecutive patients with cervical OPLL who underwent cervical magnetic resonance imaging (MRI) before surgery were reviewed. The cross-sectional area (CSA) and fatty infiltration ratio (FI%) of deep posterior cervical paraspinal muscles (multifidus [MF] and semispinalis cervicis [SCer]) were examined. We assessed the association of paraspinal muscle measurements with the clinical characteristics and clinical outcomes, such as Neck Disability Index (NDI) score. Moreover, we divided the patients into 2 groups according to the extent of the ossified lesion (segmental and localized [OPLL-SL] and continuous and mixed [OPLL-CM] groups) and compared these variables between the 2 groups. Results: 49 patients with cervical OPLL were enrolled in this study. The FI% of the paraspinal muscles was significantly associated with the number of vertebrae ( ρ = 0.283, p = 0.049) or maximum occupancy ratio of OPLL ( ρ = 0.397, p = 0.005). The comparative study results indicated that the NDI score was significantly worse (OPLL-SL, 22.9 ± 13.7 vs. OPLL-CM, 34.4 ± 13.7) and FI% of SCer higher (OPLL-SL, 9.1 ± 1.7% vs. OPLL-CM, 11.1 ± 3.7%) in the OPLL-CM group than those in the OPLL-SL group. Conclusions: Our results suggest that OPLL severity may be associated with fatty infiltration of deep posterior cervical paraspinal muscles, which could affect neck disability in patients with cervical OPLL.

Correlation between cervical lordosis and cervical disc herniation in young patients with neck pain

et al. 2019

Abnormal cervical curvature and cervical disc herniation are closely related to neck pain and should be taken into account before any treatment. However, studies have rarely reported on the correlation between cervical lordosis and cervical disc herniation in patients with neck pain. Therefore, in this study, we collect young neck pain patients with abnormal cervical curvature to evaluate the relationship between cervical lordosis and cervical disc herniation. Three hundred patients below 40 years old with neck pain were enrolled. Patient sex, age, apical vertebra, segment of intervertebral disc protrusionl, sagittal diameter of spinal duramater, saggital diameter of spinal canal, height of disc space were recorded, and the cervical curvature, and degree of cervical spinal cord compression (G/F ratio) were calculated. The change of degree of disc herniation and degree of cervical spinal cord compression were analyzed in different cervical curvature groups. Further more, collected these patients who had improved cervical curvature over a period of time, to compare the changes of degree of disc herniation, G/F ratio, and height of disc space. The median age of patients with kyphosis was lower than those with lordosis and straight cervical spine. The degree of disc herniation was higher in the straight and kyphosis groups compared to the lordosis group. Cervical lordosis was inversely correlated with the degree of disc herniation and positively with G/F ratio. Cervical curvature was significantly affected by sex, age, and the degree of disc herniation. With the improvement of cervical lordotic curvature, the degree of disc herniation decreased and height of disc space increased. The degree of disc herniation and cervical spinal cord compression are inversely correlated to cervical lordosis in young neck pain patients, and the degree of disc herniation and height of disc space can recover with the recovery of cervical lordotic curvature. These findings may indicating a link between cervical curvature and degenerative changes which have important clinical implications.

“…[1,13] The change of cervical lordotic curve was usually found by cervical spine images in clinic. [3,14] MRI has the superiority because of no radiation injury for human bodies compared with X-ray and CT. [15–17] In this report we choose the frequently-used and good repeated methods to evaluate the cervical lordotic curvature including SVA, C2–C7 Cobb and T1S. [18,19] It has reported that C2–C7 SVA showed a positive correlation with NDI which was also certified in this study.…”

Rationale: Coblation of intervertebral disc is an effective and safe minimally invasive technology for treating discogenic pain. The inactivation of neural ingrowth around annulus and tissue ablation and coagulation are currently considered to be the major causes for success of this treatment. However, it has been found by clinical researchers that its long-term clinical outcome is not optimistic. This report has given us favorable information that this situation can be improved with multimodal therapy. Patient concerns: A 61-year-old man presented with right severe neck and shoulder pain in 2014 which could not be relieved by medications. Diagnoses: According to his symptoms and signs, this patient was diagnosed with cervical discogenic pain. And discography confirmed the diagnosis. Interventions: The patient underwent coblation of cervical intervertebral disc 4–5 (C4–5) and got apparently pain relief after surgery. After 1 month, he began to perform active exercise at least 30 min every day. Outcomes: The right neck and shoulder pain completely relieved for 4 years. The cervical lordosis of this patient was restored in 2018 which was confirmed by MRI compared in 2014 and NDI (neck disability index) decreased from 58 to 10%. Lessons: This report demonstrated that it was important and essential for clinicians to educate patients with discogenic pain to perform active exercise after minimally invasive surgery.
