metaphyseal spike
A sharp fragment of bone extending from the metaphyseal region, often seen in comminuted fractures.
Full Definition
A metaphyseal spike is a pointed bone fragment that projects from the metaphyseal region of a long bone, typically occurring in high-energy trauma with significant comminution. These spikes can pose challenges during fracture reduction and fixation, as they may impede proper fragment alignment or interfere with implant placement. Metaphyseal spikes often require careful handling during surgery, sometimes necessitating trimming or separate fixation to achieve optimal reduction. Recognition of these fragments is important for preoperative planning and intraoperative decision-making.
Usage
Usage note: Use specifically for pointed bone fragments in the metaphyseal region, not for general comminution.
