*3.2. Reoperations*

Three HA were reoperated without a humeral stem revision: One patient suffered from a humerus shaft fracture after a trauma and was treated by plating. Another patient had a massive cuff tear type A [19] after a severe trauma in a motor bike accident and was repaired with an open approach. The last patient had an arthroscopic biopsy due to acute pain which appeared one year after the surgery. Bacterial cultures were negatives. During the last FU (116 months after), this last patient's range of motion was excellent. Nevertheless, Constant score was 61, especially because the patient was still in pain. None of the TSA that needed to be reoperated had to undergo a revision of prosthetic components.
