2D Long Leg - Osteotomy

The whole leg module enables a holistic view and planning of osteotomies.

Osteotomy

The osteotomy module can be used to plan femoral or tibial corrective osteotomies, with single or multiple osteotomies, using the open wedge or closed wedge technique. Axial misalignments are found automatically, and corrections are handled automatically or manually. An integrated database makes it easy to select suitable osteosynthesis components such as nails, plates, screws and more. With mediCAD®, merging partial images to create a complete long-leg image is a very simple and intuitive process.

Autoplan Osteotomy

All dimensions are determined after automatic recognition of the relevant landmarks using the “Autoplan Osteotomy” function. Axial malpositions can be corrected by specifying the relevant cuts. This function allows mediCAD to facilitate rapid and efficient preoperative endoprosthetic planning.

Osteotomy according to Dror Paley

An analysis determines the type, number, size and localization of the osteotomies. When correction is complete, all joint-related mechanical weight-bearing axes and joint tangents must lie within the normal range.

Common methods: Open Wedge oder Closed Wedge

Misalignments can be calculated using the expanded Osteotomy module according to Dror Paley. All pre- and post-operative results are shown. The process has been used for years at www.gelenkzentrum-wiesbaden.de and offers the following advantages:

Analysis of the preoperative situation
Determination of CORA/NCORA, single or multiple osteotomies
Simulation of postoperative results.
Automatic calculation of optimal angles.
Determination of the apex and actual angle of deformity from the AP and sagittal views.
Interactively select and evaluate the correction yourself.

Dror Paley’s principle of deformity correction are based on the mathemathical principles and studies of Prof. Dr. Dror Paley/Baltimore/USA and was developed for mediCAD by Prof. Dr. med. J. Pfeil and Prof. Dr. B. Gladbach/Wiesbaden.

Torsion measurement

The “Torsion measurement” function in the whole leg module enables femoral and tibial measurement of internal or external torsion. This information is helpful when performing corrective osteotomy and can be directly applied intraoperatively. The measurement of the TT-TG intervall over the distance between the sulcus of the trochlea and the tibial tuberosity can be included in cases of patellar instability.
