Injury of Ulnar Nerve at Upper Arm Level, Unspecified Arm, Sequela

An injury to the ulnar nerve at the upper arm level can cause significant discomfort and impairment. The ulnar nerve is responsible for providing sensation to the little finger and the ulnar half of the ring finger, as well as controlling certain muscles in the hand. When this nerve is damaged, it can lead to a range of symptoms and complications.

1. Numbness and Tingling: One of the most common symptoms associated with ulnar nerve injury is numbness and tingling in the affected fingers. This sensation may extend from the hand and travel up the arm. Patients often describe it as a pins-and-needles sensation.
2. Weakness and Muscle Wasting: Damage to the ulnar nerve can weaken the muscles it controls, leading to muscle wasting or atrophy. This can result in a loss of grip strength and difficulties with fine motor skills, such as picking up small objects or buttoning clothes.
3. Claw Hand Deformity: In severe cases, ulnar nerve injury can cause a claw hand deformity. This occurs when the muscles controlling the fingers and thumb become imbalanced due to nerve damage. The little and ring fingers may bend inwards, resembling a claw-like shape, while the index and middle fingers remain straight.
4. Sensitivity to Cold: Some individuals with ulnar nerve injury may experience increased sensitivity to cold temperatures in the affected hand and fingers. Exposure to cold air or water can trigger pain or discomfort.
5. Loss of Dexterity: The ulnar nerve plays a crucial role in hand dexterity. When injured, individuals may find it challenging to perform activities that require precise finger movements, such as writing, typing, or playing a musical instrument.

It is important to seek medical attention if you suspect an injury to the ulnar nerve at the upper arm level. A healthcare professional can provide an accurate diagnosis and recommend appropriate treatment options to alleviate symptoms and prevent further complications.

Remember, early intervention and proper care are essential for a successful recovery. So, if you experience any of the mentioned symptoms, do not hesitate to consult a healthcare professional.
