Vascular Injuries in Supracondylar Frx
- vascular compromise occurs in about 5-20% of children w/ supracondylar frx;
- less than 1% will be complicated by compartment syndrome and the resulting sequelae of Volkmann's contracture;
- note that a median nerve palsy, may mask a pending compartment syndrome (because there will be no pain);
- Clinical Characteristics of Severe Supracondylar Humerus Fractures in Children
- anatomic considerations:
- frxs w/ posterolateral displacement of distal fragment are more susceptible to vascular injury, since the medial spike of the proximal
humerus can tether the brachial artery;
- also consider tenting of the artery from the biciptal aponeurosis;
- ref: The bicipital aponeurosis may be involved in the anatomical etiology of arterial compromise after swelling in supracondylar fracture.
- while patient is being worked up, consider applying a continuous pulse ox so nurses can follow an objective measurement of perfusion;
- closed reduction:
- if circulation is not restored by closed reduction, immediate open reduction and surgical exploration of the artery is indicated;
- arteriography is not indicated since it provides little additional information and only delays restoration of circulation to the extremity;
- arteriography: (should it be done?)
- fracture reduction usually restores the pulses, and therefore reduction should not be delayed by waiting for an
- arteriography is only indicated if circulation is not restored following reduction

- open reduction and arterial exploration and repair
- management arterial trauma: - see intimal injuries and microvascular technique
- morbidity assoc w/ surgical exposure of the artery is low;
- procrastination will only increase patient morbidity;
- note the need to release the bicipital aponeurosis;
- ref: The bicipital aponeurosis may be involved in anatomical etiology of arterial compromise after swelling in supracondylar fracture.
- w/ possible compartment syndrome will need fasciotomy;
