Use of a new arthroscopic joint spreader/stabilizer

Area of Science:

• Oral and Maxillofacial Surgery
• Orthopedic Surgery
• Arthroscopic Surgery

Background:

• Condylar distraction is crucial in temporomandibular joint (TMJ) surgery for accessing intra-articular structures.
• Addressing lateral impingement in the TMJ necessitates improved joint space visualization and condyle stabilization.
• Current surgical techniques may face limitations in achieving optimal access and stability during TMJ procedures.

Purpose of the Study:

• To introduce and illustrate the design and application of a novel arthroscopic joint spreader/stabilizer.
• To provide a tool that facilitates TMJ arthroscopy by spreading the joint space and stabilizing the condyle-eminence relationship.
• To enhance the safety and efficacy of TMJ surgeries, including arthroscopic and open approaches.

Main Methods:

• Design and fabrication of a specialized arthroscopic joint spreader/stabilizer device.
• Demonstration of the device's use in arthroscopic TMJ surgery for joint distraction and stabilization.
• Illustration of the device's adaptability for open TMJ surgery through alternative orientation.

Main Results:

• The device effectively spreads the closed temporomandibular joint space during arthroscopic procedures.
• It provides stabilization of the condyle-eminence relationship, crucial for surgical maneuvers.
• The device is versatile, applicable to both arthroscopic and open TMJ surgical techniques.

Conclusions:

• The described arthroscopic joint spreader/stabilizer is a valuable tool for TMJ surgery.
• It addresses the need for improved access and stabilization, enhancing surgical outcomes.
• The device offers a safe and effective solution for both arthroscopic and open temporomandibular joint interventions.
