Head Resection
Once the jig is secured to the humerus with the 3mm pins, remove the IM guide by releasing the red lever and slide the guide for resection jig upwards (Figure 7). Next, remove the central Ø 6 mm intramedullary rod from the humeral canal, leaving only the cutting jig secured onto the humerus. Resect the humeral head with a blade through the guided slot of the jig (Figure 8) finally, remove the pins and the jig. If a glenoid replacement is required, please refer to the dedicated surgical technique.
Adjust the height of the resection jig level until it is aligned with the anatomic neck. Turn the red knob clockwise or counter-clockwise to move the jig proximally or distally respectively (Figure 5). A graduated scale is available to support the visualization of the height during this phase. Use the sickle to assess the resection height and once the selected height is reached secure the guide to the humerus with two Ø 3 mm pins (Figure 6).
