Brief Summary
The primary objective of this pilot trial is to assess the feasibility of a definitive trial to determine the effect of lateral patient positioning versus supine positioning with fracture table use for reamed antegrade intramedullary fixation of femur fractures.

Outcome Measures
Primary Outcomes (1)
Feasibility to conduct definitive Clinical Trial
Our primary outcome for the pilot trial is feasibility, which includes the following: * Recruitment (number of participants recruited across all sites over study period, goal of approximately 100 participants) * Cluster crossover randomization protocol adherence * Complete primary outcome collection (CT scans) on all enrolled patients. * Participant retention and follow-up data * Accuracy of 15 degrees as a cut off for malrotation
Six Months
Secondary Outcomes (9)

Study Arms (2)
Supine Positioning, Fracture Table
ACTIVE COMPARATORDuring the supine fracture table phase, patients will be positioned supine on a fracture table. The operative leg will be placed in a boot, attached to the traction limb. The non-operative leg will either be scissored away from the operating area in a traction boot (without traction placed) or placed in a stirrup at 90 degrees of hip flexion in hemi-lithotomy. A central post will be used to prevent patient movement during application of traction, and all bony prominences will be padded. Fluoroscopy will be obtained through standard practices intraoperative to document assessment of rotation.
Lateral Positioning, Free drape
ACTIVE COMPARATORDuring the lateral positioning phase, patients will be placed in lateral position after anaesthetic has been provided. A beanbag will be placed below the patient, and the patient will be safely turned to a lateral position. The beanbag will be inflated, the leg will be prepped, and a free drape will be applied. No traction will be used. Alternatively, some participating sites may use stulberg positioners rather than an inflatable beanbag, based on hospital preference. This positioning mirrors the positioning utilized for the direct lateral, posterior or posterolateral approach to a total hip arthroplasty or hemiarthroplasty

Eligibility Criteria
You may qualify if:
- Adult aged 18 years or older
- Mid shaft (Diaphyseal) femur fracture appropriate for antegrade fixation
- Surgery performed by participating surgeon or delegate
- Provision of informed consent
- Enrolled within 3 weeks of femoral shaft fixation
You may not qualify if:
- 1. Ipsilateral tibial fracture 2. Bilateral femur fracture 3. Ipsilateral femoral neck fracture 4. Ipsilateral acetabular fracture 5. Periprosthetic fracture 6. Pathologic fracture 7. Previous external fixation of femoral shaft fracture 8. Inability to be positioned in lateral decubitus because of a concomitant injury 9. Pregnancy (due to decubitus positioning) 10. Incarceration 11. Expected injury survival of less than 6 months 12. Terminal illness with expected survival of less than 6 months (expected follow up of study) 13. Inability to provide informed consent (e.g. cognitive disability, language barrier, significant delirium or dementia) 14. Currently involved in study that does not permit co-enrolment 15. Likely problems, in the judgment of study personnel, with maintaining follow-up with the patient
