REPRODUCIBILITY OF SCHATZKER CLASSIFICATION THROUGH SMARTPHONE APPLICATIONS

Area of Science:

• Orthopedic surgery
• Radiology
• Medical imaging analysis

Background:

• The Schatzker classification is a standard method for categorizing tibial plateau fractures.
• Evaluating fracture patterns requires accurate and reproducible classification systems.
• The increasing use of mobile technology in medicine prompts investigation into its diagnostic utility.

Purpose of the Study:

• To assess the intra-observer reliability of the Schatzker classification system for tibial plateau fractures when images are viewed on smartphones.
• To compare the reproducibility of Schatzker classification using smartphone-based image viewing versus traditional assessment methods.

Main Methods:

• 37 patients with tibial plateau fractures underwent imaging (radiographs and CT scans).
• Two orthopedic surgeons classified fractures twice using isolated radiographs and then combined X-ray/CT images, assessed via smartphone and in-person.
• The Kappa coefficient (k) was used for statistical analysis of intra-observer agreement.

Main Results:

• High intra-observer agreement was observed when comparing smartphone-based evaluation with traditional assessment methods.
• Statistical analysis confirmed the reliability of using smartphones for Schatzker classification.
• No significant decrease in classification accuracy was noted with smartphone use.

Conclusions:

• Smartphone applications are a reliable tool for the intra-observer classification of tibial plateau fractures using the Schatzker system.
• The use of smartphones does not compromise the reproducibility of this fracture classification.
• This finding supports the potential integration of mobile technology in orthopedic fracture assessment.
