Musculoskeletal ImagingOsteotomy
a surgical cutting of a bone, usually as a means to correct or reduce deformity (Table 1).
Osteotomy, Table 1. Some types of osteotomies.
| Closing wedge | Removal of a triangular bony wedge from one side and approximation of the resection margins |
| Opening wedge | Cutting of the bone at an angle, causing one side to open |
| Rotational | Rotation of the distal fragment on its long axis |
| Displacement | Shift in the position of the distal fragment with relation to the proximal one |
| Shish kebab | Cutting of the shaft in several places with threading of fragments of an intramedullary rod |
| Coventry high tibial | Resection of a wedge of bone from the tibial metaphysis between the joint and the tibial tubercle |
| Barrel vault | A curved osteotomy performed proximal to the tibial tubercle with rotation of the fragments to obtain the desired correction |
| Proximal femoral | Removal of wedges of bone from the femur in adduction (varus) or abduction (valgus) osteotomy |
| Salter (innominate) | Reorientation of the acetabulum with rotation of all three pelvic components forward and laterally |
| Pemberton | Cutting around the acetabulum with inferior displacement of the margin, which is wrapped around the femoral head and held in position by a bone block; the osteotomy is hinged at the pelvic Y synchondrosis |
| Steel | Rotation of the acetabulum |
| Chiari | Medialization of the femoral head with enlargement of the acetabulum |
