Interobserver Analysis of Albertoni Classification for Mallet Finger, Using Plain Radiography: Importance of the...

Area of Science:

• Orthopedics
• Radiology
• Hand Surgery

Background:

• Mallet finger, a common hand injury, requires accurate classification for effective treatment.
• The Albertoni classification is a proposed system for categorizing mallet finger lesions.
• Evaluating the reliability of classification systems is crucial for clinical consistency.

Purpose of the Study:

• To assess the intraobserver and interobserver reliability of the Albertoni classification for mallet finger.
• To determine the impact of goniometer use on the reliability of the Albertoni classification.

Main Methods:

• Sixty orthopedic surgeons evaluated 10 lateral radiographs of mallet finger patients.
• Measurements were taken both with and without the use of a goniometer.
• Intraobserver and interobserver reliability coefficients were calculated.

Main Results:

• High intraobserver and interobserver reliability coefficients were observed for the Albertoni classification.
• Goniometer use slightly increased interobserver reliability but was not statistically significant.
• The classification system proved reliable for assessing mallet finger injuries.

Conclusions:

• The Albertoni classification exhibits excellent intraobserver and interobserver reliability for mallet finger assessment.
• A goniometer is not indispensable for applying the Albertoni classification accurately.
• This classification system offers a reliable tool for hand surgeons evaluating mallet finger.
