Glenoid Bone Grafting for RTSA: Clinical & Radiographic Outcomes

Glenoid bone loss is a known issue with reverse shoulder implants and can lead to issues with
implant fixation and stability over time. To address this issue an extended peg glenoid
baseplate is used and area around plate is augmented with bone (auto or allo)graft material
to encourage bony callous growth around the implant. This study is to look at this area of
concern and determine if glenoid bone loss is occurring in the patients where these measures
have been taken to deter its development.

Inclusion Criteria:

1. Adult patients who have undergone a reverse shoulder arthroplasty with the an extended
peg baseplate and structural bone graft (autograft humeral head or allograft femoral
head).

2. Adult patients who are indicated for a long-pegged baseplate and glenoid bone grafting
(autograft humeral head or allograft femoral head) as part of their reverse shoulder
arthroplasty in our clinic,

3. bone graft is truly structural involving at least 50% of the glenoid baseplate

4. may be a primary or a revision surgery

Exclusion Criteria:

1. patients with missing baseline (preop) data,

2. patients who are unwilling to participate in a final follow-up evaluation.
