<prompt> In extension type of supracondylar fracture, the usual displacementAnterolateralAnterolateralPosteromedialPosterolateral  <response>: Ans. is d i.e., Posterolateral Types of supracondylar fracture Supracondylar fracture is broadly classified into extension type and flexion type. 1. Extension type It is the most common type 97 - 99. Distal fragment is extended tilted backwardposteriorly in relation to proximal fragment. Occurs due to hyperextension injury after fall on outstretched hands. Generally, displacement of distal fragment may be : ? Posteromedial 70-80 Posterolateral 20-30 2. Flexion type It is less common type 1-3 Distal fragment is flexed tilted forwardanteriorly in relation to proximal fragments. The mechanism of injury generally is believed to be a fall directly onto the elbow rather than a fall on outstretched hand. As the extension type fracture is more common 97 - 99, the most common elbow injury in children is extension type of supracondylar fracture.
