Periprosthetic humeral fractures associated with reverse total shoulder arthroplasty: incidence and management

The purpose of this study was to record the incidence and management of periprosthetic humeral fractures (PHF) using reverse total shoulder arthroplasty (RTSA) in our institution.
We performed a retrospective study of 203 RTSA implanted in 200 patients between 2003 and 2014. The mean follow-up was 78.82 months (range, 12–141). Mean age of the study cohort was 75.87 years (range, 44–88). There were only 25 male patients (12.5 %). We assessed the presence of periprosthetic humeral fractures studying the medical files and X-rays of all patients.
We identified seven periprosthetic humeral fractures in 203 RTSA (3.4 %): three intra-operative (1.47 %) and four post-operative (1.97 %). The average age at the time of the fracture was 75.14 years (59–83). All patients were women (100 %). Three patients with post-operative fractures type B were treated by osteosynthesis, and one patient with post-operative fracture type A was treated conservatively. All intra-operative fractures needed cerclage wire and in one case long cemented stem. All our periprosthetic fractures healed.
Surgical treatment with osteosynthesis in type B post-operative fractures with a stable stem is recommended. Conservative treatment is sufficient in non-displaced type A post-operative fracture. Special attention should be paid to bone quality patients using non-cemented stems in primary surgery but especially in revision shoulder surgery.
