Trial Outcomes & Findings for 4DCT Imaging for Improved Diagnosis and Treatment of Wrist Ligament Injuries (NCT NCT03193996)

NCT ID: NCT03193996

Last Updated: 2024-06-05

Results Overview

Baseline, Post-4DCT Viewing, Post-Arthroscopy estimates or observations were made by the attending surgeon of Geissler grading, an arthroscopic classification of carpal instability and suggested management of acute injuries to the SLIL. Lower Geissler grading indicates milder damage and suggests more conservative injury management, and higher Geissler grading indicates more severe damage and suggests more aggressive injury management.

SLIL Injury
Surgical interventions for all subjects will be determined based on combined findings of both 4DCT and standard arthroscopy. 4DCT: 4DCT will be used to assess the location of the torn scapholunate interosseus ligament.

PRIMARY outcome

Timeframe: Baseline, Post-4DCT Viewing, Post-Arthroscopy

Population: All participants who underwent 4DCT scanning were analyzed for suspected change in Geissler grade. A subset of participants who proceeded to arthroscopy were analyzed for grading agreement between arthroscopy and 4DCT scan, and between arthroscopy and clinical suspicion prior to the 4DCT scan occurring.

Baseline, Post-4DCT Viewing, Post-Arthroscopy estimates or observations were made by the attending surgeon of Geissler grading, an arthroscopic classification of carpal instability and suggested management of acute injuries to the SLIL. Lower Geissler grading indicates milder damage and suggests more conservative injury management, and higher Geissler grading indicates more severe damage and suggests more aggressive injury management.

SECONDARY outcome

Timeframe: Baseline and 1 Year Post-Surgery

Population: All subjects who completed 1-year follow-up evaluation

Baseline and one year post-surgery Patient-Rated Wrist Evaluation (PRWE) Score will measure patient perception of change. The PRWE allows patients to rate their levels of wrist pain and disability from 0 to 10, with higher numbers representing more pain and disability, and consists of 2 subscales as well as a total score: Pain subscale: contains 5 items each of which is further rated from 0-10. The maximum score in this section is 50 and minimum 0, with a higher score suggesting more severe and frequent pain. Function subscale: contains total 10 items. The maximum score in this section is 50 and minimum 0, with a higher score suggesting greater difficulty performing activities of daily living. Total score: all subscales together. The maximum score in this section is 100 and minimum 0, with a higher score suggesting more pain and disability overall.
