Type I
Non-displaced (or minimally displaced) supracondylar humerus fracture with an intact, well-aligned anterior humeral line.
CondutaNonoperative: immobilization in a long-arm cast for about 3-4 weeks, with a radiographic check at roughly 1 week to confirm maintained alignment.
RiscoStable, lowest-risk type; favorable outcome and low rate of neurovascular complication.
Displaced/angulated fracture with the posterior cortex still intact (hinge preserved). IIA = angulation only; IIB = angulation with rotational (and/or translational) malalignment.
CondutaIIA: closed reduction with casting or percutaneous pinning. IIB: closed reduction and percutaneous pinning to correct and hold coronal/rotational malalignment.
RiscoIntermediate; IIB carries greater instability and higher malreduction/malalignment risk than IIA.
Completely displaced fracture with loss of cortical contact (residual periosteal hinge may persist). IIIA = posteromedial displacement (intact medial hinge); IIIB = posterolateral displacement (intact lateral hinge).
CondutaOperative: closed reduction and percutaneous pinning, with open reduction if an acceptable closed reduction cannot be achieved.
RiscoUnstable, higher-risk type; associated with the greatest rates of neurologic and vascular injury (vascular injury occurs almost exclusively in extension type III or higher).
Periosteal disruption with multidirectional instability — unstable in both flexion and extension; often identified intraoperatively under fluoroscopy (added by Leitch).
CondutaOperative: closed reduction and percutaneous pinning, with possible open reduction and internal fixation if reduction is unstable.
RiscoMost unstable pattern; complication risk comparable to or exceeding type III.
