Quantifying osteosynthesis plate prominence - mathematical definitions and case study on a clavicle plate

Area of Science:

• Orthopedic surgery
• Biomechanical engineering
• Medical device design

Background:

• Hardware prominence is a significant clinical issue in subcutaneous plate applications.
• Current methods for evaluating hardware prominence are limited and lack reproducibility.
• A standardized, quantifiable measure for plate prominence is needed.

Purpose of the Study:

• To mathematically define and quantify plate prominence in subcutaneous plate applications.
• To compare the prominence of two different anatomical plate designs.
• To inform the development of orthopedic implants with reduced prominence.

Main Methods:

• A novel mathematical definition of plate prominence was developed, linked to cross-sectional area changes.
• Two distinct anatomical plate designs were applied to 100 clavicle specimens.
• Plate prominence parameters were evaluated and compared using the new methodology.

Main Results:

• The study successfully defined a reproducible method for quantifying hardware prominence.
• Differences in prominence were observed between the two evaluated plate designs.
• The methodology allows for objective comparison of implant designs.

Conclusions:

• The developed mathematical method provides a reliable way to quantify hardware prominence.
• This quantification is essential for designing improved subcutaneous implants.
• The findings will guide the development of implants with minimized prominence for patient comfort and aesthetics.
