Axial computed tomography of pilon fractures

Area of Science:

• Orthopedic Surgery
• Radiology
• Medical Imaging

Background:

• Computed tomography (CT) is a valuable tool for preoperative planning in complex fractures.
• Pilon fractures, involving the distal tibia, present intricate anatomical challenges.
• Accurate preoperative assessment is crucial for optimal surgical outcomes in pilon fractures.

Purpose of the Study:

• To evaluate the utility of CT scans in the preoperative planning of pilon fractures.
• To determine the impact of CT imaging on surgical decision-making for these injuries.

Main Methods:

• A retrospective study of 22 patients with pilon fractures.
• Comparison of plain radiographs with CT scans for fracture characterization.
• Detailed recording of fracture pattern, fragment number, comminution, impaction, and fracture line location.

Main Results:

• CT scans revealed increased fragment numbers in 12 patients, impaction in 6, and comminution in 11.
• The operative plan was modified in 14 (64%) patients based on CT findings.
• Additional, clinically relevant information was obtained in 18 (82%) patients through CT scans.

Conclusions:

• CT imaging provides superior detail compared to plain radiographs for pilon fractures.
• CT scans significantly influence preoperative planning and surgical strategy for pilon fractures.
• The use of CT is highly recommended for comprehensive evaluation and surgical planning of pilon fractures.
