In most studies, patients placed more than twice the prescribed pressure on the lower limb.

This can lead to devastating consequences:

Complications related to limb-fixing devices

  1. Aseptic loosening of retainer elements:
    a) loosening of osseous retainer screws
    b) migration of screws or spokes
    c) loosening of intramedullary retainer locking screws
    d) loosening of the intramedullary shaft
    e) loosening of the blade of the osseous plate or blocked epiphyseal screws (LCP, DHS, DCS systems)
    f) teething wire seam
  2. Lock deformation:
    a) deformation of the plate
    b) deformation of the intramedullary shaft
    c) deformation of the locking screws of the intramedullary retainer
  3. Fracture of the latch:
    a) fracture of osseous or intraosseous fixator screws
    b) migration of screws or spokes
    c) plate fracture
    d) fracture of the intramedullary shaft
    d) rupture of the wire seam

Complications related to bone devices

a) loosening or teething of spokes or transosseous rods of an external fixer
b) fracture of spokes or transosseous rods of an external fixator
c) destabilization or damage to the external structure of the AVF

Complications related to internal orthopedic devices

a) transplant migration
b) transplant fracture
c) fixation migration after consolidation is completed

Late load complications

a) vein thrombosis of the lower extremities
b) thromboembolic complications
c) muscle and joint contractures
d) muscle weakness and muscle volume reduction
e) gait stereotype disturbances
