Cubital tunnel syndrome occurs when the ulnar nerve becomes compressed or
irritated as it passes through a narrow space on the inside of the elbow called the cubital
tunnel. This can result in numbness or tingling in the ring and little fingers, hand weakness,
reduced grip strength, and aching pain along the inside of the elbow. Symptoms are often
more noticeable when the elbow remains bent for prolonged periods, such as while sleeping
or talking on the phone. While repetitive elbow bending and prolonged pressure on the elbow
are well-known contributors, several health conditions may also increase one’s risk:
- Smoking – Smoking can reduce blood flow to nerves, increase inflammation, and
impair healing, making nerves more vulnerable to compression. - Diabetes – High blood sugar may damage nerves and the small blood vessels that
supply them. Nerves of diabetic patients may become symptomatic under lower levels
of compression and often recover more slowly. - Hypertension – High blood pressure may affect the small blood vessels that nourish
nerves and is frequently associated with other metabolic conditions that influence
nerve health. - Excess Body Weight – Obesity may increase pressure around the elbow, contribute to
inflammation, and is strongly associated with diabetes and metabolic syndrome. - Carpal Tunnel Syndrome – Carpal tunnel syndrome and cubital tunnel syndrome
share many of the same risk factors, including diabetes, obesity, smoking, and
inflammatory conditions. In some cases, irritation of nerve roots in the neck or the
brachial plexus from which these nerves arise may reduce the nervous system’s
tolerance to compression, making symptoms more likely to develop at multiple
locations in the arm. - Osteoarthritis – Bone spurs, joint enlargement, and changes in elbow structure may
reduce the space available for the ulnar nerve. - Rheumatoid Arthritis – Chronic inflammation, tissue swelling, and joint deformity
may increase pressure on nerves and raise the likelihood of nerve entrapment.
As with other nerve entrapment disorders, seeking care early when symptoms are
mild and less frequent is often associated with better outcomes. If these factors are suspected
to contribute to a patient’s symptoms, a chiropractor may coordinate care with other
healthcare providers while providing conservative treatment aimed at improving the mobility
of the ulnar nerve along its course, including through the cubital tunnel.
