Which nerve injury is commonly associated with humeral fractures?

Which nerve injury is commonly associated with humeral fractures?

Peripheral Nerve Injury of the Upper Extremity The radial nerve is the most commonly injured peripheral nerve (Noble et al., 1998). It is also the most common nerve injury associated with humerus fracture (Omer, 1982; Samardzic, Grujicic, & Milinkovic, 1990).

Which nerve can be injured in case of fracture of humerus diaphysis and what are the clinical signs of this injury?

The radial nerve is most likely to be damaged in humerus fractures that have a lateral displacement of the distal fracture segment, as the nerve is tethered to the bone and cannot withstand the forces applied to it as a result of the displacement.

What is the commonest complication of fracture of mid shaft of humerus?

The two complications often seen are injuries to the radial nerve and nonunion of the fracture.

What are the complications of humerus fracture?

The most common complications were fracture-displacement, malunion, humeral head necrosis and malreduction.

What are the symptoms of radial nerve damage?

A radial nerve injury usually causes symptoms in the back of your hand, near your thumb, and in your index and middle fingers. Symptoms may include a sharp or burning pain, as well as unusual sensations in your thumb and fingers. It’s common to experience numbness, tingling, and trouble straightening your arm.

Why does radial nerve injury cause wrist drop?

Consequently, injury to the radial nerve results in the inability to properly utilize these extensor muscles. As a result, the hand hangs flaccidly in a position of flexion when the patient attempts to bring the arm to a horizontal position. This is known as wrist drop.

How do you test for radial nerve damage?

Imaging tests like MRI or ultrasound may be ordered to look for a tumor or other lesion that could be compressing the nerve. A doctor may order electromyelography (EMG), also known as a nerve conduction study, to confirm a diagnosis of radial nerve injury and make sure other nerves are not involved.

Which nerve is affected in Colles fracture?

A Colles’ fracture is a type of fracture of the distal forearm in which the broken end of the radius is bent backwards. Symptoms may include pain, swelling, deformity, and bruising. Complications may include damage to the median nerve. It typically occurs as a result of a fall on an outstretched hand.

When does a humerus fracture require surgery?

Most fractures of the proximal humerus can be treated without surgery if the bone fragments are not shifted out of position (displaced). If the fragments are shifted out of position, surgery is often performed to allow earlier mobility.

Which nerve is involved in fracture neck humerus?

A fracture in this area is most likely to cause damage to the axillary nerve and posterior circumflex humeral artery.

What happens if you damage your radial nerve?

This nerve controls movement and sensation in the arm and hand and extension of the elbow, wrist and fingers. Radial nerve palsy is a condition that affects the radial nerve and if damage to this nerve occurs, weakness, numbness and an inability to control the muscles served by this nerve may result.

How do you treat a radial nerve injury?

When a radial nerve injury is diagnosed, treatment is usually conservative and includes:

1. Wrist splinting to maintain function.
2. Pain management with nonsteroidal anti-inflammatory drugs (NSAIDs)
3. Physical therapy.
4. When pain is severe, a nerve block may be recommended.
