Design outcomes

Primary

Measure	Time frame
Age cut-off values for post-operative outcomes in clinical and radiological outcomes Clinical outcome: Binarised into excellent/good and fair/poor groups based on Cooney's score and calculated using ROC curves. Clinical outcome: Binarised into excellent/good and fair/poor groups based on Cooney's score, and the ROC curve is used to calculate the age cut-off value. Radiological results: ROC curves are used to calculate age cut-off values for the presence or absence of lunate fusion in simple X-rays. Radiological results: Calculate the age cut-off value using the ROC curve for the presence of lunate fusion in simple X-rays.	—
