However, arthroscopy is invasive and costly, while traditional imaging modalities, such as X-rays and MRI, often miss ligament injuries due to their static nature. A promising alternative is four-dimensional computed tomography (4DCT), which allows dynamic, non-invasive visualisation of wrist motion in real time. This study evaluates the diagnostic potential of 4DCT for detecting SLL tears by comparing its findings with arthroscopy and open surgery. <b>Methods:</b> Twenty-one patients with suspected SLL tears underwent 4DCT imaging, with independent reviews by two radiologists. The motion cycles of extension-flexion and radial-ulnar deviation were analysed. Arthroscopy was performed within a few weeks after the scan. Patients with Geissler grade III or IV tears underwent surgical reconstruction. The qualitative assessments of the SLL by radiologists and surgeons were compared, while the kinematic parameters of the injured and contralateral wrists were analysed using a linear mixed model. <b>Results:</b> Radiologists' 4DCT evaluations corresponded with arthroscopy or surgical findings in 14 of 21 patients (67%). Patients with total SLL tears showed greater scapholunate distance and scapholunate angle during all wrist movements compared with uninjured wrists. Notably, 4DCT showed greater diagnostic agreement with surgical findings than arthroscopy alone. <b>Conclusions:</b> These findings demonstrate the potential role of 4DCT in diagnosing SLL tears. Further research should focus on optimising the acquisition and analysis of the 4DCT scan and refining 4DCT parameters to distinguish partial from total SLL tears. <b>Level of Evidence:</b> Level III (Therapeutic).</p>","PeriodicalId":51689,"journal":{"name":"Journal of Hand Surgery-Asian-Pacific Volume","volume":" ","pages":"156-166"},"PeriodicalIF":0.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147312304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PROMs have been primarily developed with English-speaking populations and should be validated in the patient population in whom they are being applied. As present, the validity of commonly utilised distal radius fracture (DRF) PROMs in patients who speak Japanese is unknown. The purpose was to evaluate the validity and psychometric properties of common DRF PROMs in the Japanese population. <b>Methods:</b> A systematic review was conducted to identify published literature on Japanese DRF PROMs, using a comprehensive search strategy based on previous literature. Methodologic quality of PROM adaptation and validation was evaluated using instruments: Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures, Quality Criteria for Psychometric Properties of Health Status Questionnaire, and the Consensus-based Standards for the Selection of Health Measurement Instruments Checklist for Cross-Cultural Validity. The level of evidence was then calculated based on the above methodologic quality. <b>Results:</b> Three studies met the inclusion criteria. Amongst them, three PROMs were reported: the Disability of Arm, Shoulder and Hand (DASH), the Patient-Rated Wrist Evaluation (PRWE) and the Quick Disability of the Arm, Shoulder and Hand (QuickDASH). None of the three studies followed all six processes for adaptation, nor assessed all measurement properties. No study demonstrated the completion of more than 7 of the 15 aspects of cross-cultural validity. The PRWE, DASH and QuickDASH all had limited evidence to support the domains of measurement properties evaluating the level of evidence. <b>Conclusions:</b> There is a gap in validated PROMs for Japanese patients with DRFs.
