Three-dimensional correction of cubitus varus deformity using patient-specific 3D-printed osteotomy guides

1

This study presents a method for 3D corrective osteotomy of cubitus varus deformity using patient-specific 3D-printed templates.
2

Five patients underwent the procedure, showing significant improvement in carrying angles and elbow range of motion postoperatively.
3

The mean correction angle achieved through osteotomy was 23.51° ± 8.79°, with bone union occurring at a mean of 2.6 months.
4

All patients achieved excellent outcomes according to the Mayo Elbow Performance Index, with no recurrence of varus deformity.
5

The technique utilizes a limited lateral incision, enhancing safety and accuracy in correcting the complex 3D deformity.
