Objective: To compare four different methods for the quantitative assessment of dorsal scaphoid displacement in patients with scapholunate ligament tears.
Methods: A total of 160 consecutive patients who underwent CT arthrography to evaluate a suspected scapholunate ligament tear were prospectively included in this study approved by the local ethics committee. MR images were available for 65 of these patients.
Article Synopsis
- This study investigates the effectiveness of four-dimensional computed tomography (4DCT) in diagnosing dorsal intercalated segment instability (DISI) compared to standard imaging methods in patients suspected of chronic scapholunate instability (SLI).
- A total of 40 patients were analyzed using radiographs, arthrography, and 4DCT, leading to categorization into positive, negative, and questionable SLI groups based on radiographic findings.
- Results showed that the 4DCT measurements of the lunocapitate angle (LCA) were lower in the positive SLI group, indicating that 4DCT is useful for differentiating between SLI conditions, particularly in challenging cases.
Purpose: To assess the validity and reliability of the posterior radioscaphoid angle (PRSA), an indicator of dorsal displacement of the scaphoid, in distinguishing wrists with and without chronic scapholunate instability (SLI).
Methods: We prospectively evaluated 40 patients (22 men and 18 women; mean age, 46 ± 13 years) with suspected SLI with radiographs and computed tomography arthrography. Based on these data, 3 groups were defined: positive SLI (n = 16), negative SLI (n = 19), and questionable SLI (n = 5).
We performed a prospective study to evaluate the values of dynamic four-dimensional computed tomography in assessing suspected chronic scapholunate instability. Forty patients were evaluated with radiographs, arthrography, and four-dimensional computed tomography. On plain radiographs and computed tomography, we found 16 patients with definite scapholunate instability, five with questionable scapholunate instability, and 19 with absence of scapholunate instability.
