Seven weeks postoperatively, the patient slipped in the bathroom and was found to have a superior patellar pole periosteal sleeve avulsion injury. We describe a rare case of periosteal sleeve avulsion fracture of the superior patella pole after tibial tubercle avulsion fracture ORIF in an adolescent male patient. The etiology of this injury pattern may be due to altered tensile forces transmitted through the extensor mechanism related to the previous surgery. Orthopaedic surgeons should be aware of this unusual sequela.

A 69-year-old woman with a history of breast cancer, on long-term antiresorptive medications, was treated with carbon fiber cephalomedullary nails for bilateral atypical femur fractures. Her thigh pain was presumed to be from metastatic lesions and was treated with radiation without standard imaging. The index procedure was complicated by a left nail fracture. The patient underwent exchange cephalomedullary nail fixation with plate augmentation. At 1 year, the patient was asymptomatic with radiographs demonstrating healing. This case highlights the importance of appropriate imaging in all patients with thigh pain on antiresorptive therapy and features an uncommon complication of carbon fiber cephalomedullary nail fixation.
