what is dynamisation in inter locking nail fixation?

Question

ex in fracture shaft of femur inter locking nailing is one type of treatment

Answer 1

Dynamisation of the interlocking nails used to mend fractures of the femur, tibia, or other large weight barring bones is when inserted nails are changed. Often, when unreamed interlocking nails are used, the weight barring capabilities are not as great as when reamed nails are used. Sometimes reamed nails are used to replace unreamed (dynamisation), along with bone grafting.
