This is for removing cancellous bone from the resected humeral head to graft onto the metaphysis and thus encourage bone bonding. |
Retaining the metaphysis and the bony bridges enables 3-point stabilisation which generally means bolting is unnecessary. |
The intramedullary axis along which the humeral prosthesis is inserted is that of the proximal metaphysis since a change in curvature occurs at the humeral diaphysis. |
The two ideas were linked, because one cannot conceivably get good wedging in the metaphysis without having a modular implant system. |
The choice between 10 right and left sizes helps chose the best implant for the size of the metaphysis. |
The device investigates the speed and the transmission of ultrasound through the distal metaphysis of the first phalanges of the long fingers of the hand. |
