2023
Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Central venous access is necessary in a multitude of clinical situations, including vascular access, vasopressor and caustic medication delivery, central venous pressure monitoring, volume resuscitation, total parental nutrition, hemodialysis, and frequent phlebotomy. There are three veins in the body that are accessed for central venous cannulation: the internal jugular, the subclavian, and the...

This protocol describes a procedure for serial sampling of femoral bone marrow (BM) without requiring the sacrifice of mice. This procedure facilitates longitudinal studies of the BM composition of mice over time and provides serial access to cells within the BM for ex vivo and transplantation studies.

FAQs
Fracture location and pattern help determine which implant can provide appropriate stabilization while maintaining the femur’s alignment. Surgeons weigh whether screws, plates, or intramedullary nails can transfer load across the injury and limit harmful movement. This individualized selection connects the fracture’s geometry with mechanical demands and the expected path of healing.
Mechanical stability limits movement at the fracture, but healing also depends on protecting the blood supply and surrounding tissue. Excessive disruption can undermine the biological environment needed for new bone formation, whereas insufficient stability may impair alignment and load transfer. Femoral fixation therefore requires simultaneous attention to implant mechanics and local tissue preservation.
Screws, plates, and intramedullary nails represent different implant options rather than universally interchangeable choices. Their selection depends primarily on fracture location and pattern, along with the need to balance stability, tissue protection, and load transfer. Comparing them in this context means asking which option best supports alignment and healing for the specific injury.
Maintaining alignment helps the femur heal in a mechanically useful position, while fixation limits movement across the injury as new bone forms. During recovery, rehabilitation and progressive weight bearing are adjusted around the stability achieved by the construct and the healing process. These factors influence whether the patient regains limb function and mobility.
Planning begins with the fracture’s location and pattern, then considers the implant options that can restore alignment and provide suitable stability. The strategy should also account for protection of blood supply and surrounding tissue. This approach links operative decisions to the biological requirements for healing rather than treating implant selection as a purely mechanical problem.
Evaluation focuses on whether the fracture achieves union, meaning healing across the injury, and whether the patient recovers useful mobility and limb function. Clinicians also consider complications and the patient’s progression through rehabilitation and weight bearing. These outcomes reflect the combined effects of alignment, implant stability, fracture biology, and tissue preservation.
