Categorias num relance

Cat.	Significado	Conduta	Risco	Fonte
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.	okfonte 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.	okfonte 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).	okfonte 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.	okfonte PMC4294919 Treatment section, Type IV (multiplanar instability).
