 Treatment will be self-administered for 20 minutes once daily by the patients. The device will be equipped with a system to document compliance with the treatment. Treatment will continue until the subject has greater than 50 cortical bridging on CT scanning with multi-planar reconstruction. Union will be confirmed by both an orthopedic surgeon and by an independent musculoskeletal radiologist. Treatment will also be terminated if the subject continues to have non-union present at 6 months post-operatively. Subjects will be assessed for union using serial CT scans until union is documented. CT scans will take place at 7-9 weeks, 12-14 weeks and then every 4-6 weeks thereafter as per current clinical standards of practice. Standard scaphoid and wrist radiographs will be completed within 1 week of the CT scan. Patients who do not have documented union will be classified as persistent non-unions but will be asked continue to attend clinical follow ups until 1 year. Patients will be required to attend baseline follow up at 8, 12, 16, 36 and 52 weeks for functional assessments. Patients requiring additional surgery such as bone grafting as deemed necessary by their treating surgeon will be scheduled at the surgeons discretion and the surgery will be recorded as a trial adverse event.
