De validiteit van de Western Ontario Stability Index en de Carter Rowe Score - De beste keuze in uitkomstmaten na schouderstabilisatie: Door de arts gemeten of zelfgerapporteerde?

Purpose of this study: to test the validity of the Dutch version of the Western Ontario Shoulder Instability Index (WOSI) and to compare the physician-based Carter Rowe Score (CRS) with the patient-based WOSI. Methods: 36 consecutive patients with a history of shoulder instability who had undergone arthroscopic transglenoid Bankart repair were evaluated with the CRS and the WOSI. The average follow-up was 63.6 months (SD 25.6). Results: the WOSI showed a moderate correlation with the Carter Rowe Score Ir = 0,441. The Dutch version can be reliably used in the Dutch population. Conclusion: the WOSI is a good primary outcome tool for evaluation of the results of stabilisation procedures of the shoulder, whereas the CRS is an additional, disease-specific analytic tool to find and correct the reasons for the low WOSI score.
