Cannulated Paediatric Osteotomy System (CAPOS)
The AO series of angled blade plates for children (infant, toddler, child, adolescent) are essential implants for proximal femoral osteotomy providing strength, accurate correction, and a good hold, particularly in soft bone such as in cerebral palsy(CP).
Users have found placement of the chisel difficult, especially in the deformed and narrow proximal femur frequently found in CP. The CAPOS system provides for insertion of the chisel over a guide wire, after insertion of the guide wire through an adjustable angled guide for precision osteotomy. Another feature is a cutting block that attaches to the chisel after placement; this ensures that the proximal osteotomy cut is firstly, the correct distance from the chisel to accommodate the plate offset, and secondly, parallel to the chisel. The plates have not been cannulated at this stage. With a single chisel track in the femoral neck it was felt that it should be easy to place the implant. We believe that CAPOS will extend the life of classical AO implants well into the 21st century and look forward to users feedback.
