Final answer:
A screw in dynamically interlocking an IM Nail should be placed at both proximal and distal ends, facilitating bone stability and healing. The procedure requires precise execution under fluoroscopy to minimize complications.
Step-by-step explanation:
When dynamically interlocking an IM Nail, a screw should be placed at the proximal and distal ends of the intramedullary nailing to secure the nail and promote proper alignment and stabilization of the bone fracture. Intramedullary nailing is a common orthopedic procedure used to treat long bone fractures, particularly of the femur, tibia, and humerus.
Procedure and Considerations
During the procedure, the surgeon inserts the IM Nail into the marrow canal of the bone following reduction of the fracture. The positioning of the screw is crucial as it must be inserted in such a way that it does not compromise the bone's blood supply or interfere with surrounding soft tissues or joints. Additionally, precise screw placement can help to prevent postoperative complications such as malalignment, nonunion, or instability of the fracture.
Dynamic Interlocking of IM Nails
Dynamic interlocking allows for controlled axial movement which can facilitate bone healing by promoting callus formation. Proper placement of the screw involves the use of fluoroscopy to ensure accurate positioning. Once the screw is placed, the surgeon confirms the stability of the fixation and the proper alignment of the bone. The operative surgeon should have extensive knowledge of the relevant anatomy and be adept with the technical aspects of the procedure to minimize risks and optimize patient outcomes.
