Spinal osteosynthesis fixing frame has hooks engaging vertebral processes and connected by parallel rods

摘要

The spinal osteosynthesis frame has a pair of hooks (2,27) engaging the sides of the vertebrae (T) and mounted on rods (1) extending along a section of the spine. The hooks are shaped to engage the transverse spinal processes (5). Each pair of hooks are connected by parallel rods (6a,b) which are elastically centred and form a transverse arch.
