Modular
Shoulder Surgical Procedure
In some
cases, such as osteoporosis or erosive osteolysis, the canal
diameter to proximal humeral relationship is greater or smaller
than normal. Other cases may require a longer stem length
to bypass a defect in the humeral shaft. In such cases, the
modular elements of the system may be combined to provide
an optimal proximal and distal fit.
When the
modular elements are to be used, the configuration of the
reamer and trial must match the modular humeral stem and extension
combination as described below.
For extensions longer than 150mm a Reamer
Extension is needed to produce sufficient reaming depth.
Where
an Extension diameter of 11mm and smaller is used a 12mm diameter
hole must be reamed proximally to the depth of the Humeral
Body. To do this, assemble a TRIAL EXTENSION corresponding
to that to be implanted onto the BODY REAMER. Then using the
hole reamed in the shaft ream the proximal humerus to the
appropriate depth.
After
humeral reaming is complete assemble the selected diameter
and length TRIAL EXTENSION to the MODULAR HUMERAL STEM TRIAL.
Use this assembly as the Humeral Trial.
The
Humeral Component is assembled by first fully inserting the
Extension into the Modular Humeral Component and then inserting,
and tightening the Locking Screw using the TORQUE SCREW DRIVER.
The modular head is then assembled in the usual way.
