1.Overview
A supracondylar humeral fracture is a fracture that occurs in the relatively weak part of the bone between the humeral condyle and the humeral stem. It is most common in children aged 5-8 years old and accounts for about 50%-60% of all elbow fractures. They are extra-articular fractures and recover well after timely treatment. However, it is a more serious injury because of the combination of neurovascular injury and residual deformity, and should be given sufficient attention.
2. Clinical manifestations and diagnosis
Local manifestations, pain, swelling, subcutaneous ecchymosis, posterior protrusion deformity of the elbow, restricted movement, normal posterior triangular relationship of the elbow, combined with X-ray manifestations are easy to diagnose.
3. Common complications of supracondylar fracture of humerus.
(1) Volkmann ischemic contracture
(2) Elbow entropion deformity
(3) Brachial artery dissection
(4) Nerve injury
4.Classification
According to the different violence and the direction of fracture displacement, it can be classified as
(1) Extension type supracondylar humerus fracture
(2) flexion type supracondylar humerus fracture
5.Treatment
(1) Non-surgical treatment.
a. The non-displaced humerus can be suspended by triangular scarf for 3 weeks only.
b.Suspension of ulnar hawkbone
(2) Surgical treatment: two types of surgery
a.percutaneous needle fixation
b.cut and reset internal fixation
(3) Postoperative rehabilitation treatment
Either manipulation reset external fixation, or incision reset internal fixation.
