Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Disability of the arm,shoulder and hand ( DASH) score ranging from 0 to 29 | The final end results will be assessed according to DASH score , a DASH score ranging from 0 to 29 was thought by most respondents to be the point where patients/clients were 'no longer considering their upper-limb disorder a problem . | 2 years | |
Primary | Mayo wrist score of 60 - 100 will be satisfactory | The final end results will be assessed according to modified Mayo wrist score of 60 - 100 will be satisfactory .
Secondary (subsidiary): |
2 years | |
Secondary | Carpal Alignment Before and After VBG | the articular surfaces of the proximal and distal carpal rows should form three smooth arcs , the spacing between all carpal bones should be 1-2 mm in antroposterior view and the distal radius, lunate and capitate should be in a straight line in lateral view | 2 years | |
Secondary | Scaphoid Height-to-length ratio | The mean normal H/L ratio in the sagittal plane was 0.61 (range, 0.54-0.69) and in the coronal plane 0.42 (range, 0.36-0.48). | 2 years | |
Secondary | Scapholunate angle | Scapholunate angle is the angle between longitudinal axes of lunate and scaphoid (tangential line from the dorsum of scaphoid) in the lateral radiograph the scapholunate angle should be between 30o and 60o in the neutral position | 2 years | |
Secondary | Radio-lunate angle | Radiolunate angle is the angle between the longitudinal axes of radius and lunate in lateral view | 2 years | |
Secondary | Lateral interscaphoid angle | Normal lateral intrascaphoid angle averages 30 degrees | 2 years |
