- Discussion:
- Component Characteristics:
- cylindrical reamers: 6.5, 9, 12, 15 mm;
- angle of inclination:
- 125, 130, 135, 140 deg options;
- if inclination is between sizes choose the smaller size;
- humeral retroversion:
- determined from humeral neck cut;
- use osteotome to mark a notch through the inclination guide;
- the notch is created for the humeral stem;
- broaching:
- use the previously made fin to determine retroversion;
- broach is driven in upto the marked inclination angle;
- trial implants:
- trial neck is slid onto the stem and tightened w/ posterior screw;
- trial stem is then impact down into the canal;
- head size:
- use calipers to determine head diameter;
- two thickness are available for the 50 and 52 mm heads;
- articular offset:
- offset can be dialed in order to preserve the posterior offset, which allows perfect cover of the transected humeral surface;
- 8 positions are possible, which are read from the superior pole of the neck, once the component is removed
