Screws used in the Fixation of the small fracture and reconnection of the fractured bone using plates. The main purpose of the screws in orthopedics, dental and maxillofacial surgery, etc. In some of the Neurosurgery Screws used for the fixation of the Cranial bone after the craniotomy procedures and cranioplasty.
Screws type made up of special type stainless steel, Titanium, etc.
Main used in pre-drilled and tapped holes
Used to fix the plates and bones
Used to fix the plate correctly aligned fractured segments of bone.
Different Screw Types
Thread diameter is shorter when compared to cancellous screw. continuous threads can be seen the same as cancellous.
Spherical in shape with threaded fully.
The blunt tip with uniform threading
Before application of Cortical screw tapping needed
plating Radial bone, Ulnar bone, humeral bone, Tibial bone, Femoral shaft fracture
used in fixation of
Proximal tibia and distal tibia
Used in Medial malleolus of the ankle
Used rarely in the fixation like scaphoid fracture and radial head fracture
It’s embedded into the bone and not removed after fixation
Either cortical or cancellous type
The hollow uniform hole helps in drilling and insertion of screw using Guidewire
Accurate screw placement and less soft tissue dissection
Used in Malleolar screw fixation, Distal humerus fracture, Tibial condylar fracture, and a femoral neck fracture
Dynamic hip screw
