Patient-specific core decompression surgery for early-stage ischemic necrosis of the femoral head
Fig 2
The reconstructed specimen model was smoothed, core decompression was digitally simulated, and navigation templates were designed.
A. The reconstructed specimen model was smoothed and the glass ball was marked in red in the picture. B. The depth of the osseous part of the core decompression channel was measured, and all data were saved in STL format. C. A template with four holes (3 mm in diameter) was created. Three holes were adapted to the positioning wires on the specimen, and the fourth hole was adapted to the drilling direction of the guide needle for the core decompression.
