Background: This is the first report on the incidence of proximal humerus osseous changes and associated clinical consequences in reverse total shoulder arthroplasty combined with a latissimus dorsi tendon transfer (RTSA+LDT).

Methods: A multicenter, retrospective review identified all patients who had undergone a primary RTSA+LDT and had at least 3-month radiographic follow-up between 2012 and 2017. Data collection included demographics, oral steroid use, repair technique for LDT fixation, radiographic humeral osseous changes, complications, and need for revision surgery.

Results: Twenty-four patients were included with an average age of 70.7 ± 7.9 years and follow-up of 16.3 (3-50) months. Ten patients (41.7%) developed osseous changes at the transfer location. There was no increased risk of developing osseous changes based on the surgical fixation technique (P = .421). Average time to earliest radiographic detection of osseous changes was 2.7 ± 1.7 months, with all changes occurring at or before 6 months. Two patients developed proximal humerus fractures, of which 1 had osseous changes through which the fracture occurred.

Discussion: RTSA+LDT may place the proximal humeral cortex at greater risk than previously described. Using a long-stem prosthesis in the setting of RTSA+LDT may limit the consequences of this complication.
