What is Unicortical screw?

Unicortical locking screw These are often blunt tip screws that will abut the femoral stem. The addition of unicortical locking screws creates a length stable construct. These screws should not be used in isolation and must have either bicortical screws or cerclage fixation for adequate lasting stability.

What does Bicortical fixation mean?

Traditionally, bicortical fixation is the standard practice, where both dorsal and palmar cortices of the metacarpal are drilled through, with screws engaging both cortices.

What is Bicortical displaced fracture?

Severely displaced (bicortical displacement): The outer cortices of the two fractures fragments are not touching, and the displacement is greater than or equal to the width of the rib.

What is Unicortical fracture?

They may be caused by a single traumatic incident or by repetitive trauma (stress fracture). Stress fractures are often unicortical and difficult to diagnose. Intraarticular hairline fractures may propagate and eventually displace, becoming chip fractures.
