Long-term Coated and Non-coated Tibia Nails

For this retrospective cohort study, medical records of patients treated between 2005 to 2019 with the UTN PROtect and/or ETN PROtect for tibia fractures or tibia revision cases will be examined. In comparison to this cohort, patients who received an uncoated tibia nail are examined as well. Demographics, pre-surgical health status, details on fracture type or on revision, treatment decision and surgery details, postoperative reoperation and revision, surgical site infections, time to union, and adverse events will be registered. In a subgroup, additional information including clinical outcomes and patient satisfaction will be assessed by clinical exam. Patients who still carry a nail and feel discomfort at the surgical site or present with a medical condition which demands an imaging will receive an x-ray of the tibia. The xray is not part of the standard study protocol.
