Sir,We thank Dr. Yashavanth kumar for his query [1] regarding our device [2]Osteoporotic and comminuted fractures may not be a good indications for the device and so they were excluded. The bigger the diameter of the piston the bigger will be the window in the anteromedial cortex. For this reaason we have kept the diameter to 10 mm, however you can change the angle of the outer sleeve in the sagital plane and push in the graft. Yes, we can push in some stored bone graft through the sleeve if needed to support the depressed fragment. The number os screws depends on the size of the elevated fragment and should be decided intraoperatively. I can get you the device for you. Kindly mail me your postal address to my E-mail adress.Thank you and best wishes
