Tronco-conical locking plate in distal radius fractures

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Biomedical Engineering

Background:

• Volar locked plates are standard for distal radius fractures (DRF).
• Existing threaded screw-hole mechanisms have limitations.
• A novel tronco-conical locking mechanism was developed to address these issues.

Purpose of the Study:

• To evaluate the clinical and radiological outcomes of a new tronco-conical locking mechanism for volar plating of DRF.
• To assess peri-operative and general complications associated with this new fixation technique.

Main Methods:

• Eighty patients with DRF treated with tronco-conical locking volar plates were retrospectively analyzed.
• Data collected included clinical and radiological outcomes, and peri-operative complications.
• Follow-up averaged 11.4 months.

Main Results:

• 78 patients completed follow-up; all fractures healed within three months.
• 36 patients had excellent, 40 had good, one fair, and one poor result based on Gartland and Werley scoring.
• Five complications were noted, none related to the locking mechanism itself.

Conclusions:

• The tronco-conical locking mechanism demonstrated outcomes comparable to existing methods.
• Observed complications were not attributed to the new locking system.
• Further research is recommended to fully assess functional and radiographic parameters.
