Abstract
Purpose
The purpose of the study was to provide reference data for computer-aided joint space analysis based on a semi-automated and computer-aided diagnostic system for the measurement of metacarpal-phalangeal and proximal-interphalangeal finger joint widths; additionally, the determination of sex differences and the investigation of changes in joint width with age were evaluated.
Patients and methods
Eighty hundred and sixty-nine patients (351 female and 518 male) received radiographs of the hand for trauma and were screened for a host of conditions known to affect the joint spaces. All participants underwent measurements of joint space distances at the metacarpal-phalangeal articulation (JSD-MCP) from the thumb to the small finger and at the proximal-interphalangeal articulation (JSD-PIP) from the index finger to the small finger using computer-aided diagnosis technology with semi-automated edge detection.
Results
The study revealed an annual narrowing of the JSD of 0.6% for the JSD-MCP and for the JSD-PIP. Furthermore, the data demonstrated a notable age-related decrease in JSD, including an accentuated age-related joint space narrowing in women for both articulations. Additionally, males showed a significantly wider JSD-MCP (+11.1%) and JSD-PIP (+15.4%) compared with the female cohort in all age groups.
Conclusion
Our data presented gender-specific and age-related normative reference values for computer-aided joint space analysis of the JSD-MCP and JSD-PIP that could be used to identify disease-related joint space narrowing, particularly in patients with osteoarthritis and rheumatoid arthritis commonly involving the peripheral small hand joints.
