Femoral retrograde intramedullary nail I
The Femoral Retrograde Intramedullary Nail is an orthopedic implant used in the treatment of fractures of the femur (thigh bone). The term "retrograde" refers to the fact that the nail is inserted in the opposite direction to the usual or traditional method. In the case of femoral fractures, a retrograde nail is inserted from the knee towards the hip.
Here is the informatioin of Femoral Retrograde Intramedullary Nails:
1. Purpose: The primary purpose of the intramedullary nail is to stabilize fractures of the femur by providing internal fixation. This helps in promoting faster healing, minimizing pain, and allowing for early mobilization.
2. Insertion Technique: Unlike antegrade nailing, where the nail is inserted from the hip towards the knee, retrograde nailing involves insertion from the knee towards the hip. This approach may be chosen based on the type and location of the femoral fracture.
3. Material: the femoral Retrograde Intramedullary nails are typically made of titanium. These materials are chosen for their strength, biocompatibility, and durability.
4. Locking Mechanism: Intramedullary nails often have a locking mechanism to secure the nail in place. Locking screws are inserted through the nail into the bone to prevent movement at the fracture site.
5. Length and Diameter: The nails come in various lengths and diameters to accommodate different patient anatomies and fracture patterns.
6. Surgical Technique: The surgical procedure involves making an incision at the knee, accessing the intramedullary canal of the femur, and inserting the nail through the canal to the site of the fracture. Locking screws are then placed to secure the nail.
7. Rehabilitation: Intramedullary nailing allows for early mobilization and weight-bearing, which can contribute to a quicker recovery compared to some other forms of fracture fixation.
Anatomic reduction: The Titanium Distal Femoral Retrograde Nail is designed to fit anatomically in the medullary canal, allowing indirect reduction.
Stable fixation: The femoral retrograde intramedullary nail acts as an internal splint that controls but does not prevent micromovements of the fragments. It provides relative stability that leads to an indirect healing through callus formation.
Preservation of blood supply: The instruments and implants in the Distal Femoral Retrograde Nail system permit a percutaneous technique and less tissue stripping than other treatment methods. An intramedullary approach results in decreased blood loss compared to plate fixation.
Early, active mobilization: The Distal Femoral Retrograde Intramedullary Nail provides secure fixation which permits controlled, early, active rehabilitation conducive to optimal recovery.
Indications:
The Distal Femoral Retrograde Intramedullary Nail is indicated for the stabilization of fractures of the distal femur and/or diaphyseal fractures in which a retrograde approach is indicated.
These include:
-supracondylar fractures, including those with intra-articular extension
-ipsilateral hip/shaft fractures
-ipsilateral femur/tibia fractures
-femoral fractures in the multiply-injured patient
-fractures proximal to a total knee arthroplasty
-fractures distal to a hip implant
-fractures in the morbidly obese patient
-pathologic fractures including those in osteoporotic bone
-malunions
-nonunions
