- Abstract:
- Background: Painful habitual instability of the thumb basal joint is an underdiagnosed condition that can immensely impair the function of the entire hand. It also increases the risk of developing arthritis of the thumb basal joint. Clinical examination and radiological imaging form the cornerstone of diagnostics, but early detection is complex. In this study, two objective and easily obtainable radiological parameters were examined as potential risk factors of CMC-1 instability. Methods: This was a multicenter study. The patient data was collected both from the Orthopedic Hospital Speising and the Department of Plastic, Aesthetic and Reconstructive Surgery at the University Hospital Graz. Clinical data and radiographic images from 68 patients were obtained and analyzed retrospectively for the purpose of this study. 33 of said patients suffered from painful habitual instability of the thumb basal joint, 35 served as a control group. The two main objectives, the slope angle and the bony offset of the thumb joint, were gathered from the x-rays in dorso-palmar and zither-player position and statistically analyzed. Results: No relevant differences between the groups regarding slope angle could be found. However, there was a statistically significant association between the bony offset and the risk of suffering from CMC-1 instability. In addition to a high bony offset, female gender also proved to be an important risk factor. Conclusion: The results of this study indicate a connection between a high bony offset in the trapeziometacarpal joint and the likelihood of painful habitual instability of the thumb basal joint. These findings could be valuable in early detection and will allow more efficient treatment of this condition in the future.
