Guide groove for pinning subcondylar fractures

Area of Science:

• Orthopedic Surgery
• Oral and Maxillofacial Surgery

Background:

• Subcondylar fractures of the mandible are common injuries.
• Accurate Kirschner wire placement is crucial for successful fracture fixation.

Purpose of the Study:

• To evaluate the efficacy of a guide groove on the mandibular ramus for directing Kirschner wires in subcondylar fracture fixation.
• To assess the utility of an extended guide groove for complex cases.

Main Methods:

• A guide groove was surgically created on the lateral surface of the mandibular ramus.
• Kirschner wires were inserted through the guide groove to pin subcondylar fractures.
• An extended groove design was utilized for challenging fracture patterns.

Main Results:

• The guide groove effectively directed the Kirschner wire to the correct position for subcondylar fracture fixation.
• The extended groove provided accurate guidance in difficult and complex fracture cases.
• This technique facilitates precise pin placement, potentially improving surgical outcomes.

Conclusions:

• A guide groove on the mandibular ramus is a valuable tool for accurate Kirschner wire placement in subcondylar fractures.
• The extended groove design offers enhanced accuracy for complex cases, simplifying surgical procedures.
