Outcome Measures

Primary Outcomes (1)

  • Comparing Glenoid Component Positioning to Pre Operative Planning

    Final implant position will be determined by comparing the position of the glenoid component on the post-operative CT scans with the implant position planned pre-operatively on the surgical simulator. These measurements will be in degrees.

    1 month post op

Secondary Outcomes (1)

  • Intra-operative Photographs

    Intra-operative

Study Arms (2)

Glenoid Positioning System

EXPERIMENTAL

For the patients randomized to the GPS group, the surgeon will be given the GPS patient specific instrumentation and a model of the glenoid surface showing the exact placement and fit of the GPS alignment instruments.

Procedure: Glenoid Positioning System

Standard Group

NO INTERVENTION

Each surgeon will use their standard methods of pre-operative planning using the pre-operative x-rays and CT scan.

Interventions

Design and fabrication of patient specific instrument for placement of a guide pin to be used to aid in bone preparation for placement of a metaglene and its fixation screws or anatomic glenoid component

Glenoid Positioning System

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • All patients otherwise indicated for primary reverse or anatomic total shoulder replacement that are able to get a pre-operative CT scan at the Cleveland Clinic will be considered eligible for enrollment. All patients will be consented in the office as part of the pre-operative consent for surgery and all will need to randomization at the time of surgery

You may not qualify if:

  • Patients will be excluded if they have significant metal in the joint that results in metal artifact on the CT scan, thereby compromising the ability to visualize the glenoid on the pre-operative simulator.
