The ulnar nerve runs from the neck down into the hand, it plays a pivotal role in the sensation of the fourth and fifth finger and certain hand movements. Its entrapment, often referred to as “cubital tunnel syndrome”, can cause an array of symptoms, predominantly cantered around the elbow, wrist, and hand areas.
Common symptoms of ulnar nerve entrapment include:
- Tingling or numbness in the ring and little fingers, often described by sufferers as “pins and needles.”
- Weakened grip strength, making it challenging to hold objects such as a cup or drinking glass.
- A feeling of the hand “falling asleep”, especially at night time.
- Sensitivity to cold temperatures or a cold feeling in the ring and small fingers.
To diagnose ulnar nerve entrapment, healthcare professionals rely on a combination of clinical examination and diagnostic tests. A detailed medical history often helps pinpoint the onset and progression of symptoms. During a physical doctors appointment, the Tinel’s sign test may be used, where light tapping over the nerve at the elbow will reproduce tingling sensations in the affected fingers.
Further, diagnostic tests such as nerve conduction studies (NCS) and electromyography (EMG) can assess nerve function and measure the electrical activity of muscles, providing definitive evidence of nerve compression and subsequently information to decide if surgery is required.
In conclusion, ulnar nerve entrapment, while common, requires a precise diagnosis to ensure effective treatment. Recognising symptoms and seeking early medical advice can lead to better outcomes and prevent prolonged discomfort and pain.
