When is cerclage wire used for osseous fixation?

• A. Long oblique and spiral fractures near a joint
• B. Simple transverse fractures
• C. Comminuted diaphyseal fractures
• D. Distal radius fractures

Answer: (A)

Cerclage wires are used to help reduce and stabilize fracture fragments that tend to rotate or separate in oblique or spiral patterns, especially when the fracture is near a joint. By wrapping the wire around the bone and tightening, you gain circumferential grip that pulls the oblique fracture ends into alignment and provides axial compression across the fracture line. This is particularly helpful when a fragment near a joint is difficult to capture with screws alone and when you plan to add plating for definitive fixation.

This technique is less useful for simple transverse fractures, where direct plate compression suffices; it’s not ideal for comminuted diaphyseal fractures, where multiple small fragments won’t be held reliably by a single wire; and it isn’t typically the preferred method for distal radius fractures, where other fixation methods are favored.
