“…Tenodesis techniques involve the usage of metal anchors or bone tunnels, and this can create areas of potential weaknesses that predispose the proximal humerus to fracture under stress. Previous cases have described such a complication post biceps tenodesis, and these have been presented in Table 1 [7][8][9][10][11][12][13]. It had been suggested in cadaveric literature that interference screws in biceps tenodesis procedures provide better fixation compared to all-suture anchors.…”

Intraoperative periprosthetic humeral fractures are a rare but debilitating complication of reverse shoulder arthroplasty and can occur during multiple stages of the procedure. Prior biceps tenodesis has been found to reduce cortical humeral strength and predispose the patient to humeral fracture. We present a case of a 68-year-old female with a previous history of biceps tenodesis due to an irreparable rotator cuff tear. Months later, and after symptoms persisted, a reverse shoulder arthroplasty was performed. During the surgery and while performing final reduction, a fracture line was observed involving the hole used for the previous tenodesis procedure. The fracture was repaired, and the patient reported favorable outcomes. We report several factors that might have contributed to sustenance of this intraoperative fracture including prior biceps tenodesis, use of a press fit humeral stem, and the sex of the patient.

“…Humeral fractures following tenodesis can occur days to months following the procedure due to trivial trauma or triggers (Table 1) [7][8][9][10][11][12][13]. The size of the hole relative to bone diameter has been found to have an antagonistic effect on bone strength [16].…”
