Gamekeeper's thumb. Evaluation by arthrography and stress roentgenography
Summary
Acute rupture of the ulnar collateral ligament in the metacarpophalangeal joint is reviewed. A new roentgenographic technique for thumb stress abduction was developed and correlated with surgical findings.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Radiology
Background:
- Acute rupture of the ulnar collateral ligament (UCL) of the metacarpophalangeal (MCP) joint is a common injury.
- Accurate diagnosis and management are crucial for restoring hand function.
Purpose of the Study:
- To review previously reported cases of acute UCL rupture of the MCP joint.
- To develop and evaluate a standardized roentgenographic technique for assessing thumb stability.
- To correlate radiographic findings with surgical pathology.
Main Methods:
- A comprehensive review of 197 previously reported cases.
- Development of a standardized roentgenographic technique using stress abduction of the thumb in 30 normal subjects.
- Correlation of the developed technique, arthrography, and surgical findings in 20 patients.
Main Results:
- The study established a standardized roentgenographic technique for evaluating UCL rupture.
- A correlation was reported between the abduction arc measured by the new technique, arthrogram findings, and surgical pathology.
Conclusions:
- The developed roentgenographic technique provides a reliable method for assessing UCL integrity of the MCP joint.
- This technique aids in the diagnosis and management of acute UCL ruptures, improving surgical correlation.
