The "funny bone", is the familiar point found behind the
elbow where a significant hit with enough force can cause pain and tingling sensations to shoot down the length of the forearm. The sharp pain to the elbow frequently dissipates quickly but for some individuals, the same type of symptoms may radiate constantly due to
another condition affecting the elbow.
Cubital tunnel syndrome occurs when there is a compression of the ulnar nerve as it passes on the posterior, inside portion of the elbow. The ulnar nerve can become trapped between the bone and the skin in a tunnel called the cubital tunnel, due to the fact that there is no muscle to function as a cushion to protect the nerve. Cubital tunnel syndrome is known as the second most common condition occurring in the arm as a result of nerve impingement.
Cubital tunnel syndrome frequently results when the nerve is
stretched or compressed for an extended amount of time. When holding the phone, for example, the arm is bent for undetermined periods, during which
the ulnar nerve stretches inside the elbow and may progressively begin to cause
nerve irritation. Also, prolonged compression on the nerve may result when the
inside part of the elbow is pushed to lean against a hard surface, pushing the
ulnar nerve against the bone.
This condition can gradually develop over time or can occur after trauma from an accident, such as an elbow fracture. Cubital tunnel syndrome symptoms include numbness and tingling sensations beginning from the elbow
that trail down the inside of the forearm and into the hand. Other symptoms
include decreased sensation and tenderness on the elbow. Severe cases of the
condition may result in the individual having difficulty gripping and holding
on to objects.
Cubital tunnel syndrome can be treated without surgery,
according to Dr. Alex Jimenez. A physical therapist can easily diagnose a
person’s level of the condition and follow by determining and recommending
lifestyle changes to avoid further injury to the elbow in order to allow the
irritation of the nerve to decrease. The physical therapist may also follow
treatment with exercises to restore the range of motion to the affected arm and
strengthen the surrounding muscles to aid in the rehabilitation.
