Three-dimensional corrective osteotomy for treatment of cubitus varus after supracondylar fracture of the humerus in children

Postoperative accuracy analysis of three-dimensional corrective osteotomy for cubitus varus deformity with a custom-made surgical guide based on computer simulation

“…1,11,16,17,24,25 To solve these problems, several methods of corrective osteotomy have been performed. [3][4][5][6][7][8][9]14,15,32,37 However, conventional corrective osteotomy can leave a certain degree of deformity because it is not always easy to correct complex 3D bone deformities with preoperative planning based on plain radiographs and free-hand operation. 9,10,15,30,38 Since 2003, we have been developing an original computer program that employs 3D imaging to simulate anatomic correction of the upper limb deformity based on computed tomography (CT) data.…”

Three-dimensional analysis of cubitus varus deformity after supracondylar fractures of the humerus

“…1,12,18,24 Various surgical procedures have been advocated to correct the deformity, which classically includes varus, extension, and internal rotation. 8,15,20,30,34 A simple lateral closing wedge osteotomy, which corrects the varus component of the deformity, 4,28 and an anterolaterally based closing wedge osteotomy, 20,35 which corrects both varus and hyperextension, are widely performed for this condition. However, some investigators believe that an osteotomy, which leaves a residual rotation deformity, does not completely improve the appearance of the elbow.…”

Diagnostic accuracy of 2- and 3-dimensional imaging and modeling of distal humerus fractures

“…Three-dimensional (3D) imaging seems more intuitive as structures look similar to what the surgeon sees in the operating room. Computer generated bone models have been successfully used in the planning of surgery to address malunion of the distal radius or humerus fractures, [1][2][3]13,20,21,24 and might be even more intuitive for understanding the injury and planning treatment.In 1 study, 3D computed tomography (3DCT) of fractures of the distal humerus improved both the intra-and the interobserver reliability of the AO classification system, but only improved the intraobserver agreement for fracture characteristics and treatment recommendations when …”
