Retrograde Femoral Nail

Introduction

Femoral retrograde intramedullary nail is an orthopedic implant used for the treatment of femoral fractures. Retrograde femoral nail is a relatively new technique, which involves inserting an interlocking nail from the bottom of the femur upwards. This is in contrast to traditional methods, where the nail is inserted through a small incision in the knee joint and secured in place using screws at both ends.

Indications

Suitable for femoral fractures, including stable and unstable distal metaphyseal fractures, diaphyseal fractures, intra-articular fractures, periprosthetic fractures, non union fractures, delayed union fractures, to prevent potential pathological fractures and intramedullary nail fixation.

Advantage

1. Three locking screws are cross fixed at the proximal end to enhance anti rotation stability and prevent the main nail from swinging in the medullary cavity. The design of tension compression locking screws can effectively solve the problem of compression fixation of the distal femoral bifurcation.

2. After surgery, dynamic compression can be applied to the dynamic hole at the distal end of the main nail to promote fracture healing.

3. The proximal 6 ° of the main nail conforms to the physiological curvature of the femoral condyle, making it easy for the main nail to be inserted and operated.

4.90 ° cross fixation hole at the distal end of the main nail enhances anti rotation stability.

5. It does not affect the function of the hip abductor muscle.

6. Facilitate surgical fixation for patients with multiple injuries.

Surgical steps for reverse femoral nail insertion

The surgery is performed under general anesthesia, with the patient lying on their back and their legs raised. The orthopedic doctor will make a small incision above the knee joint and insert a guide wire through the knee upwards into the femur. The guide wire will be used to guide the nails into place. Then insert the nail through the knee joint into the femur, and place screws at both ends to secure it in place.
