[Clinical study of digital six-axis external fixation frame based on CT data for tibiofibular fractures]

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Trauma Care

Background:

• Tibiofibular fractures require precise reduction and stable fixation for optimal healing.
• Traditional external fixation methods may have limitations in accuracy and invasiveness.
• Digital technology offers potential for enhanced precision in orthopedic fracture management.

Purpose of the Study:

• To evaluate the clinical efficacy of a novel digital six-axis external fixation frame in treating tibiofibular fractures.
• To assess the accuracy of fracture reduction and patient outcomes using this CT-based system.
• To determine the suitability of this technique for complex fractures, including open injuries.

Main Methods:

• A retrospective analysis of 43 patients with tibiofibular fractures treated with a self-developed digital six-axis external fixator.
• CT data was used to guide the design and adjustment of the external fixation frame.
• Fracture reduction accuracy was measured radiographically; functional outcomes and complications were assessed using the Johner-Wruhs score.

Main Results:

• Satisfactory fracture reduction was achieved in all patients, with minimal displacement and angulation.
• Patients demonstrated early weight-bearing ability and achieved good to excellent functional limb scores.
• The external fixation frame was removed after fracture healing, with no secondary fractures reported.

Conclusions:

• The digital six-axis external fixator provides precise reduction and firm fixation for tibiofibular fractures.
• This minimally invasive technique promotes rapid healing and is particularly beneficial for patients with compromised soft tissues.
• The system represents an advancement in the surgical management of tibiofibular fractures.
