Can We Estimate the Amount of Malrotation in Supracondylar Humerus Fractures After CRPP

Purpose: This is an attempt to correlate radiographic parameters of a malrotated supracondylar humerus fracture(SCHFX) with degrees of rotational malalignment to assist surgeons in intraoperative assessment of reduction quality. Methods 3D-printed models were printed, simulating a transverse SCHFx with 5 o, 10 o, 15 o, 20 o, 25 o, and 30o of malrotation. Four different scenarios were developed with (1) lateral cortical axis of rotation, simulating a lateral periosteal hinge(L), (2) medial cortical axis of rotation, simulating a medial …
