This compression or bridging technique prevents harmful movement that could lead to malunion or nonunion, ensuring the bone heals in the correct anatomical position. Material Composition and Properties Material science is paramount in the success of bone screws, as the device must perform under demanding biological and mechanical conditions.

Allergic reactions to metal alloys, though rare, can cause chronic inflammation. Immediately after insertion, a fibrin clot forms around the implant, followed by the recruitment of inflammatory cells.
The modulus of elasticity of the screw material is a critical factor; a mismatch with the host bone can lead to stress shielding, where the implant bears too much load, hindering the bone's natural remodeling and weakening it over time. Over-reaming of the pilot hole is avoided to maintain the structural integrity of the bone.

Over subsequent weeks, osteoblasts lay down new bone tissue, a process known as osteogenesis, which gradually encapsulates the screw. Soft tissue handling is minimized to preserve blood supply, which is vital for healing.
