Pre-osteotomy plate application technique for ulnar shortening.

Area of Science:

• Orthopedic surgery
• Biomedical engineering
• Surgical technique development

Background:

• Osteotomy gaps present a challenge in fracture fixation.
• The AO/ASIF LC-DC plate offers a self-compressing mode.
• Effective management of osteotomy gaps is crucial for bone healing.

Purpose of the Study:

• To describe and evaluate a technique for closing and compressing osteotomy gaps using the AO/ASIF LC-DC plate.
• To demonstrate the application of the plate's self-compressing feature.
• To provide a method for managing modest osteotomy gaps.

Main Methods:

• Provisional application of the AO/ASIF LC-DC plate with two screws per side of the osteotomy.
• Oblique osteotomy cuts made through 70% of bone diameter, with gap measurement.
• Completion of cuts, re-application of the plate, and eccentric drilling.
• Use of a 3.5 mm universal drill guide for eccentric drilling of up to five holes.
• Placement of an interfragmentary screw across the osteotomy.

Main Results:

• The technique allows for the closure and compression of osteotomy gaps up to 4 mm.
• Eccentric drilling facilitates gap reduction.
• Successful application of the AO/ASIF LC-DC plate's self-compressing mode.

Conclusions:

• The described technique is a simple yet effective method for managing modest osteotomy gaps.
• Careful planning and execution are essential for successful outcomes.
• The AO/ASIF LC-DC plate's self-compressing capability is a valuable tool in orthopedic surgery.
