NICE has been notified about this procedure and it is part of its work programme.
The Interventional Procedures Advisory Committee (IPAC) will consider this procedure and NICE will issue an interventional procedures consultation document about its safety and efficacy for 4 weeks’ public consultation. IPAC will then review the consultation document in the light of comments received and produce a final interventional procedures document, which will be considered by NICE before guidance is issued to the NHS in England, Wales, Scotland and Northern Ireland.
||The procedure is done using spinal or general anaesthesia. Following a high
tibial osteotomy, a magnetic nail is inserted into the medullary canal of the tibia
using image intensification and positioned below the tibial plateau. The nail is
secured proximally and distally using multiple locking screws. After wound
closure the position of the magnet inside the nail is identified and this is marked
on the skin. The procedure takes about 2 hours.
During the post-operative phase, the magnetic nail can be gradually lengthened
or shortened by placing the external remote controller over the marked skin to
control the exact amount of the opening of the osteotomy. New bone forms in the
wedge defect that is generated. The nail is removed when the desired alignment
has been achieved and bony consolidation is complete, assessed radiologically.
The aim is to correct the malalignment of the knee to reduce symptoms.
