Retrograde intramedullary nail: what to know

Intramedullary means inside the hollow centre of a bone. Retrograde insertion means the surgeon introduces the nail from the end nearer the knee rather than from the hip. Locking screws at the ends can help control rotation and length while the fracture heals. This approach may suit some fractures near the lower femur or other selected situations, depending on the fracture pattern, soft tissues and overall health. The operation is fracture fixation surgery, not a treatment chosen from the nail alone; imaging and examination guide the plan.

Before surgery, discuss medicines, allergies, smoking, previous operations and the weight-bearing plan. Afterward, follow wound care and mobility instructions, use prescribed walking aids, and attend physiotherapy when advised. Early rehabilitation usually focuses on safe movement, swelling control and maintaining strength, then progresses as healing is seen on follow-up imaging. Do not increase walking or lifting because pain has improved; bone healing and stability are assessed separately. Ask how long the implant is expected to remain and whether removal could ever be considered.

Contact the surgical team for increasing wound redness, drainage, fever, worsening pain, new numbness, a cold or discoloured foot, or difficulty moving the limb. Seek urgent care for sudden chest pain, breathlessness, fainting, or severe calf swelling. A fall, new deformity or sudden loss of function should be reported promptly, even if the incision looks normal.

Ask why a retrograde route is suitable, where the entry point will be, what alternatives exist, how much weight you may place on the limb, and how healing will be checked. Clarify pain control, physiotherapy milestones, work or driving restrictions, and symptoms that need urgent review.
