Cervical curvature variations in patients with infraocclusion

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.

“…More than 90% of patients exhibiting infraocclusion had their cervical curvature categorized as either straight or kyphosis. In contrast, 36% of control subjects had their cervical curvature classified as lordosis [10]. Lordosis refers to an abnormal, exaggerated inward curvature of the spine, creating a concave shape.…”

Effective body posture entails the correct alignment of body parts in relation to each other and is crucial for preserving balance, stability, and the efficient operation of muscles and joints. The major types of posture abnormalities such as lordosis, kyphosis and scoliosis can lead to alterations in various areas of the body, such as stomatognatic system. The potential correlation between malocclusion and body posture remains a subject of controversy. The aim of this review is to investigate and evaluate the association between posture defects and malocclusion on the basis of literature. This literature review has analyzed 18 studies. Inclusion criteria: clinical researches published after 2010, regarding children and adults. PubMed and Google Scholar has been searched to identify the papers. In 18 analyzed studies, 2133 patients were enrolled (including 979 children aged 4-18). A positive correlation between scoliosis and different types of malocclusion has been proven by six papers. There are also other noteworthy dependencies, such as overjet and pelvic torsion, kyphosis and sagittal position of mandible, skeletal Class III and torticollis, cross bite and scapula plane. Adolescent Idiopathic Scoliosis significantly affects the stomatognathic system, leading to issues like crossbite, crowding, increased overjet, overbite, partial open bite, and midline deviation. Orthopedists should collaborate with orthodontists for comprehensive treatment, particularly during developmental stages.
