IRCT201404127841N5 IRCT 2014-04-18 Isfahan University of Medical Sciences Comparing of two surgical method, radial shortening and vascularized bone graft, in Kienböck’s disease Comparing of clinical outcomes of radial shortening and radial shortening combined with vascularized bone graft in patients with early stage of Kienböck’s disease 2013-01-01 anticipated 24 Complete https://irct.ir/trial/8288 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment. N/A Kienböck’s disease. Intervention 1: In first group we use radial shortening up to 3 mm. The level of the osteotomy is at the diaphyseal area, nearly 7 cm proximal to the distal articular surface of the radius bone. Intervention 2: In second group we use radial shortening combined with Vascularized bone graft. We use radial shortening up to 3 mm and the level of the osteotomy is at the diaphyseal area, nearly 7 cm proximal to the distal articular surface of the radius bone.The graft and its pedicle are dissected to the transverse volar carpal artery origin.The bone graft is then placed in an about 4 mm deep hole which is made in middle of lunate bone and was stabilized with a fine 5 mm pin.
