Study population: Adult patients with non-pathologic distal femur and femoral shaft fractures treated with the Depuy Synthes Advanced Retrograde femoral nail.

Brief summary: This study is a retrospective chart review of the safety and performance Standard of Care data on individuals that have previously been implanted with the femur nail of the RFNA System for the internal fixation of the femur. Demographics, medical history, primary diagnosis, mechanism of injury, type of injury, clinical and radiographic evaluation of bone consolidation, and device-related adverse events were collected. Descriptive statistics were applied to the data collected.


Eligibility criteria: Inclusion Criteria:

1. Subjects 18 years or older at the time of index procedure
2. Subjects who received the Depuy Synthes Advanced Retrograde Nail in accordance with the indications for use.
3. Subjects who have at least 6 months of follow-up.

Exclusion Criteria:

* Subject with less than 6 months of follow up, pathologic fractures, and patients \< 18 years of age will be excluded from the study.
