The whole leg module enables a holistic view and planning of osteotomies.
Osteotomy according to Dror Paley
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.
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:
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.
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.
