Cervicothoracic Junction Disc Herniations Respond to Preston Chiropractic

Thoracic disc herniations. They’re not very ordinary. They are not discussed much. But thoracic disc herniations do exist. The C7/T1 disc herniations are even more unusual and are presented in the spine literature more because of their unusualness. Chiropractic Associates welcomes unusual! Unusual merits care and attention. Chiropractic Associates tends to unusual presentations like thoracic disc herniations, especially those at the C7/T1 level of the spine which is also known as the cervicothoracic junction where the neck joins with the upper back.

C7/T1 disc herniations are unusual from their adjacent segments, cervical disc herniations (neck) and thoracic disc herniations (mid-back). Why? They are inclined to herniate laterally (out to the side) rather than centrally. What makes that unusual? The C7/T1 disc level doesn’t typically have Luschka joints. These joints secure the intervertebral discs in place and reduce the risk of herniation. They permit flexion and extension and limit the amount of lateral flexion in the cervical spine. There is a report of a rare occurrence of a central C7/T1 disc herniation that instigated lower extremity numbness and weakness along with gait disturbance though in a patient who tells of no or very little hand pain or numbness that would otherwise be anticipated. (1) Know that your Preston chiropractor will perform a careful examination and figure out the source of your pain with awareness of unusual incidences like this.

C7/T1 disc herniations account for 3.5% to 4% of all herniated cervical discs. (2,3) They tend to be misdiagnosed owing to their unusual neurological findings. C7/T1 disc herniations (aka herniations of the C8 disc) instigate weakness in hand muscles.  The C8 nerve roots extend outward between the C7 vertebra and the T1 vertebra. (4) They are positioned above the C8 disc making it unusual for a disc herniation to compress the C8 nerve. (5) Nevertheless when it does, a C7/T1 disc herniation usually shoots pain down the arm into the ring and pinky fingers (which may be confusing as pain here is also indicative of ulnar neuropathy). (3,4) It won’t be confusing to your Preston chiropractor though! Chiropractic Associates knows the tests to do and questions to ask to determine the diagnosis.
