8Transphyseal screw

Placement of the transphyseal screw

The 3.2 mm thread hole for the transphyseal 4.5 mm screw is drilled in distomedial direction across the physis into the epiphysis. It should cross the growth plate at approximately one quarter of its width.

Note: drilling should be started in parallel direction to the growth plate (1) and while drilling the drill should gradually be rotated proximally until it comes to lie flat on the bone (2).
