Which of the following should be included in an orthopedic set-up?

In the context of an orthopedic setup, the key elevator is a crucial instrument that is specifically designed for use in orthopedic procedures. Its primary function is to elevate and retract the periosteum from bone, facilitating access to the surgical site. The ability to effectively manipulate soft tissue layers is essential during orthopedic surgeries, which often involve exposure of the bones and joints. The design of the key elevator allows for precise control and minimal tissue trauma, making it a valuable tool in the orthopedic surgical field.

Other instruments listed serve different purposes and are typically not associated with orthopedic setups. For example, the Smith perforator is meant for use in neurosurgery, Potts scissors are used in vascular surgery to dissect and cut tissues, and the Heaney clamp is commonly used in gynecological surgeries. Each of these instruments has specific applications that do not align with the primary goals of an orthopedic procedure, which involves the treatment of musculoskeletal conditions. Understanding the specific roles of surgical instruments helps in assembling the appropriate tools for a given specialty, ensuring that the surgical team is equipped for a successful operation.
