Describe the rationale for using sonography to monitor dorsal capsuloligamentous healing after arthroscopic dorsal capsuloligamentous repair (ADCLR) of the scapholunate complex.
Identify the sonographic technique and standardized measurement approach used to assess dorsal capsule thickness following ADCLR.
Summarize the postoperative temporal changes in dorsal capsule thickness and associated functional outcomes reported after ADCLR.
1. According to the article, what was the primary objective of using sonography following arthroscopic dorsal capsuloligamentous repair (ADCLR)? A. To evaluate postoperative capsuloligamentous healing by measuring dorsal capsule thickness B. To replace arthroscopy as the diagnostic standard for scapholunate injuries C. To quantify carpal bone alignment during wrist motion D. To assess postoperative tendon integrity
2. What sonographic equipment was used to measure dorsal capsule thickness in this study? A. A curvilinear transducer operating at 1–5 MHz B. A phased-array transducer operating at 2–8 MHz C. A matrix transducer with three-dimensional capability D. A linear transducer operating at 3–12 MHz
3. According to the article, at which postoperative time point did dorsal capsule thickness reach its maximum value following ADCLR? A. Preoperatively B. At 6 weeks postoperatively C. At 3 months postoperatively D. At 6 months postoperatively
4. How were sonographic measurements standardized to improve reproducibility in this study? A. By standardizing wrist position and imaging settings, including depth and focus B. By using dynamic stress maneuvers during scanning C. By averaging measurements from multiple operators D. By performing measurements only on the contralateral wrist
5. Which functional outcome measures were used to assess clinical improvement following ADCLR? A. Mayo Wrist Score and grip strength testing B. Visual analog scale and range of motion C. Disabilities of the Arm, Shoulder, and Hand questionnaire only D. Patient-Rated Wrist Evaluation and quick Disabilities of the Arm, Shoulder, and Hand questionnaire
6. What was observed regarding dorsal capsule thickness at 6 months postoperatively? A. Thickness remained significantly increased compared with preoperative values B. Thickness continued to increase beyond 3 months C. No significant difference compared with preoperative and contralateral measurements D. Thickness could not be reliably measured at this time point
7. According to the article, what potential clinical value does sonographic monitoring offer after ADCLR? A. It confirms bone union following carpal fixation B. It predicts long-term osteoarthritis development C. It eliminates the need for postoperative clinical evaluation D. It may help guide decisions regarding healing progression and the need for earlier revision
