Definition Of Screw – An orthopedic nurse is a nurse who specializes in treating patients with bone, limb, or musculoskeletal disorders. Nonetheless, because orthopedics and trauma typically follow one another, head injuries and infected wounds are frequently treated by orthopedic nurses.
Ensuring that patients receive the proper pre-and post-operative care following surgery is the responsibility of an orthopedic nurse. They play a critical role in the effort to return patients to baseline before admission. Early detection of complications following surgery, including sepsis, compartment syndrome, and site infections, falls under the purview of orthopedic nurses.
Definition Of Screw
Instinctively we expect a screw to squeeze these things together when tightened.

Screws are those things whose are widely used for fixation of small fracture fragments, avulsion fractures, interfragmentary compression and along with plates for fixation to the bone surfaces.
[Ref-John Ebnezar’s, “Orthopedics for Nurses”, 4″ edition, P-70]
There are three types of screws;
A. Cortical Screws: These screws are threaded whole length and have a diameter of 2 to 4.5 mm. This functions as a positional screw or a lag screw for interfragmentary compression.
B. Cancellous Screws: These screws have larger threads for more purchase in the soft cancellous bone. It is available as 16 mm, 32 mm length and 4 mm to 6.5 mm in diameter.
C. Malleolar Screws: These are similar to the cancellous screws except that they have a pointed tip. They are used to fix the malleolar fractures.
