| Código | Rótulo | Critérios | Conduta | Risco | Localizador | Verificado |
| --- | --- | --- | --- | --- | --- | --- |
| I | Type I | Non-displaced (or minimally displaced) supracondylar humerus fracture with an intact, well-aligned anterior humeral line. | Nonoperative: immobilization in a long-arm cast for about 3-4 weeks, with a radiographic check at roughly 1 week to confirm maintained alignment. | Stable, lowest-risk type; favorable outcome and low rate of neurovascular complication. | PMC4294919 (Alton et al., 'Classifications In Brief: The Gartland Classification of Supracondylar Humerus Fractures', Clin Orthop Relat Res 2015), Treatment section, Type I. | ✓ |
| II | Type II | Displaced/angulated fracture with the posterior cortex still intact (hinge preserved). IIA = angulation only; IIB = angulation with rotational (and/or translational) malalignment. | IIA: closed reduction with casting or percutaneous pinning. IIB: closed reduction and percutaneous pinning to correct and hold coronal/rotational malalignment. | Intermediate; IIB carries greater instability and higher malreduction/malalignment risk than IIA. | PMC4294919 Treatment section, Type IIA and IIB. | ✓ |
| III | Type III | 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). | Operative: closed reduction and percutaneous pinning, with open reduction if an acceptable closed reduction cannot be achieved. | Unstable, higher-risk type; associated with the greatest rates of neurologic and vascular injury (vascular injury occurs almost exclusively in extension type III or higher). | PMC4294919 Purpose and Treatment sections, Type III. | ✓ |
| IV | Type IV | Periosteal disruption with multidirectional instability — unstable in both flexion and extension; often identified intraoperatively under fluoroscopy (added by Leitch). | Operative: closed reduction and percutaneous pinning, with possible open reduction and internal fixation if reduction is unstable. | Most unstable pattern; complication risk comparable to or exceeding type III. | PMC4294919 Treatment section, Type IV (multiplanar instability). | ✓ |
