Corrective osteotomies in complex proximal femoral deformities can be challenging wherefore subsidies in preoperative planning and during surgical procedures are considered helpful. Three-dimensional (3D) planning and patient-specific instruments (PSI) are already established in different orthopedic procedures. This study gives an overview on this technique at the proximal femur and proposes a new indirect reduction technique using an angle blade plate.
Using computed tomography (CT) data, 3D models are generated serving for the preoperative 3D planning. Different guides are used for registration of the planning to the intraoperative situation and to perform the desired osteotomies with the following reduction task. A new valuable tool to perform the correction is the use of a combined osteotomy and implant-positioning guide, with indirect deformity reduction over an angle blade plate.
An overview on the advantages of 3D planning and the use of PSI in complex corrective osteotomies at the proximal femur is provided. Furthermore a new technique with indirect deformity reduction over an angle blade plate is introduced.
The understanding of complex deformities at the proximal femur is enhanced by the use of preoperative 3D planning and the additional PSI allow an accurate intraoperative execution. Further advancements in this technique, such as indirect deformity reduction over an angle plate, allow complex corrections with fewer surgical steps and less harm to the surrounding soft tissue.
