Rotation of the distal fracture fragment in the supracondylar fracture is a contributing factor in the development of the cubitus varus deformity. Computed tomography (CT) is superior to conventional radiography in the assessment of the position of fracture fragments and was used to study 20 patients with supracondylar fractures after reduction.

Elbow - Supracondylar fracture - Lateral. This is the commonest elbow fracture in children. A joint effusion raises the anterior and posterior fat pads, indicating intra-capsular injury. Less than one third of the capitulum of the humerus lies in front of the anterior humeral line. The distal fracture fragment is pulled posteriorly by the triceps

Gartland Type I fractures are often difficult to see on X-rays since there is only minimal displacement. Most of these fractures consist of greenstick or torus fractures. The only clue to the diagnosis may be a positive fat pad sign. Supracondylar fractures of the femur are fractures involving the distal 9 to 15 cm, as measured from the articular surface of the femoral condyles. These fractures are relatively uncommon, accounting for only 7% of femoral fractures. Fractures may be impacted, undisplaced, comminuted, and involve the articular surface of the femur. Flexion type supracondylar fractures account for less than 5% of all supracondylar fractures.

Posttraumatic humerus deformity was first reported in 1948 and sporadically thereafter. AVN deformity has been classified as type A (AVN of the lateral ossification center) and type B (AVN of the entire medial crista and a metaphyseal portion). 2018-09-18 · Supracondylar fracture of the humerus is a common childhood injury to the elbow. If treated quickly, either by immobilizing with a cast or by surgery, the prospects for full recovery are very good. Supracondylar humeral fractures are the most common fracture around the elbow in the paediatric population. They are the result of a fall on an outstretched arm and are seen primarily in the first decade of life (4).

In type 1 fractures, there is minimal or no displacement; in type 2, there is clear displacement, although the distal fragment is still hinged to the proximal fragment; and in type 3, there is complete separation of the fracture frag- ments.

Five cases of AVN after supracondylar humerus fracture were reviewed from the Children's of Alabama database. Four of the 5 patients were female. Four patients sustained a Gartland type III fracture, and 1 patient sustained a nondisplaced Gartland type I fracture. Age at time of injury ranged from 5 …

Supracondylar fracture radiology

The Gartland classification of supracondylar fractures of the humerus is based on the degree and direction of displacement, and the presence of intact cortex. It applies to extension supracondylar fractures rather than the rare flexion supracondylar fracture .

The supracondylar region is the weakest point in the developing elbow and therefore is commonly injured. AP and lateral radiographs of the elbow demonstrate a lucency across the distal humerus consistent with a supracondylar fracture. A line drawn along the anterior border of the humerus does not intersect the middle third of the capitellum, indicating that the fracture is somewhat posteriorly angulated. Epidemiology. Unlike the much more common extension supracondylar fracture which are seen in children, flexion fractures are seen in older (adult) patients..

Posterior Fat Pad Sign – Supracondylar Fracture. Diagnosis: Supracondylar fracture with posterior fat pad sign. Modality: X-Ray. Findings: The posterior fat pad sign is indicative of a likely fracture.

• These AAOS references should be reviewed prior to engaging in the treatment of a pediatric supracondylar humerus fracture. Supracondylar humeral fractures are a common paediatric elbow injury, but are almost never seen in adults. The peak age of incidence is 5-7 years.

The AHL was normal in only 5.8% of the cases reviewed (4 of 68 cases).

In children, the most common occult elbow fracture is a supracondylar fracture; In adults, the most common occult fracture of the elbow is a radial head fracture
