Which nerve is damaged in supracondylar fracture of humerus?

The anterior interosseous nerve is most commonly affected by the initial injury, however ulnar nerve palsy is the most common post-operative complication.

What nerve is injured in supracondylar fracture?

Supracondylar fractures can be significant injuries with a reported incidence of associated nerve injuries between 11% and 15%. Posteromedially displaced fractures are more likely to have an associated neurological injury;10 most commonly the radial nerve is affected.

Which nerves can be injured while humerus is broken?

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).

What is the most common nerve injured in Shaft of humerus fracture?

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 supracondylar fracture of humerus?

The difficulty in maintaining the reduction and ultimately the cubitus varus is the most frequent long-term complication with an incidence ranging from 3 to 57%. Adequate reduction and pinning has dramatically decreased this incidence.

How does a supracondylar fracture of the humerus occur?

A supracondylar fracture is an injury to the humerus, or upper arm bone, at its narrowest point, just above the elbow. Supracondylar fractures are the most common type of upper arm injury in children. They are frequently caused by a fall on an outstretched elbow or a direct blow to the elbow.

How do you know if your ulnar nerve is damaged?

Common symptoms of ulnar nerve injury Burning feeling in hand, arm or finger. Increased arm numbness or tingling while typing or writing. Increased finger numbness or tingling while typing or writing. “Pins and needles” sensation (prickling) in the hand, arm or fingers.

What is the most common nerve injured in a displaced pediatric supracondylar humerus fracture?

(1) In children with supracondylar fracture the most often injured nerve is median nerve. (2) The incidence of vascular and nerve complications positively correlates with the progression of fracture according to Gartland classification.

Why does fracture of humerus cause wrist drop?

Broken humerus–The radial nerve can be damaged if the humerus (the bone of the arm) is broken because it runs through the radial groove on the lateral border of this bone along with the deep brachial artery. Lead poisoning–Wrist drop is associated with lead poisoning due to the effect of lead on the radial nerve.

How is median nerve entrapment after humeral fracture?

Median nerve entrapment after supracondylar humeral fracture in children is rare. We report a case of Gartland type III supracondylar humeral fracture complicated by an entrapment of the median nerve following closed reduction and percutaneous pinning in a 5-year-old child.

What are the complications of A supracondylar fracture?

Complications most commonly include nerve palsies (anterior interosseous nerve neurapraxia (most common) and then median nerve, radial nerv, & ulnar nerve palsy). Supracondylar Fracture – General Review X-Ray Image Mechanism of Injury

How is supracondylar humerus fracture type 2 treated?

Type 2 – There are differing opinions on the treatment of Type 2 supracondylar humerus fractures. Treatment may consist of placement of a long arm cast with close follow-up or closed reduction and percutaneous pinning.

Are there nerve injuries associated with pediatric humeral fractures?

Methods: A literature search identified studies that reported the incidence of nerve injury presenting with displaced supracondylar fractures of the humerus in children. Meta-analysis was subsequently performed to evaluate the risk of traumatic neurapraxia associated with supracondylar fractures.
