Design outcomes

Primary

Measure	Time frame
The end-point of the study is a healed period of the scaphoid delayed unions or nonunions, as judged on CT examination	—

Secondary

Measure	Time frame
1) Functional outcomes are assessed with the Disability of the Arm, Shoulder, and Hand Japanese version (DASH-JSSH) 2) The study is a healed period of the scaphoid delayed unions or nonunions, as judged on radiographic examination 3) Functional outcomes are assessed with the Visual Analog Scale (VAS) for pain 4) Functional outcomes are assessed with the grip strength improvement at pre-operation, and 16 weeks after operation period. 5) Functional outcomes are assessed with the Range of motion of the wrist improvement at pre-operation, and 16 weeks after operation period.	—
