TBW Patella
Overview
Tension Band Wiring (TBW) Patella” is a surgical technique used for the treatment of fractures of the patella (kneecap). The patella is a small, flat bone that plays a crucial role in knee joint function. Fractures of the patella can occur due to trauma or direct injury.
- Tension band wiring involves the placement of a wire or wires around the patella in a specific configuration to create a tension band effect. This is usually done using stainless steel or titanium wire.
- The wire is passed through small drill holes in the patella and then wrapped around specific parts of the patella to create a stable construct.
- The tension band converts the forces acting on the patella during knee movement, particularly when the quadriceps muscle contracts, into compression forces, aiding in fracture stabilization.
Why it's done
TBW Patella may be recommended for several reasons, including:
- Tension band wiring is commonly used for transverse fractures of the patella. Transverse fractures occur when the patella breaks straight across, dividing it into upper and lower fragments.
- The patella is subject to tensile forces, especially when the quadriceps muscle contracts during activities like walking or jumping. Tension band wiring converts these tensile forces into compression forces, enhancing the stability of the fracture site and promoting healing
- The tension band construct, created by passing wires around the patella in a specific configuration, stabilizes the fractured fragments. This stability is crucial for proper alignment and healing.
- By stabilizing the patellar fracture, tension band wiring aims to restore the normal anatomy and function of the patella. This, in turn, contributes to improved knee joint function and mobility.
- Tension band wiring may allow for earlier initiation of rehabilitation exercises. Early mobilization and physical therapy are essential for preventing stiffness and promoting optimal recovery.
- Tension band wiring is often performed using a minimally invasive approach, involving a small incision. This can result in less soft tissue trauma and a potentially faster recovery compared to open surgical techniques.
Risk
TBW Patella, can pose potential risks and complications. Some of these include:
- Hardware Irritation
- Infection
- Nonunion
- Malunion
- Breakage of Hardware
- Joint Stiffness
- Nerve or Blood Vessel Injury
- Joint Adhesions
- Skin Complications
- Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE)
How do I get ready for TBW Patella ?
Preparing for TBW Patella involves several steps to ensure a smooth procedure and recovery:
- Schedule a thorough consultation with your orthopedic surgeon. Discuss your symptoms, medical history, and the proposed treatment plan.
- Undergo necessary diagnostic tests, such as X-rays or CT scans, to provide detailed information about the patellar fracture.
- Complete a comprehensive medical evaluation to assess your overall health and identify any pre-existing conditions that may affect the surgery.
- Review your current medications with your healthcare provider. Adjustments may be necessary, especially for medications that affect blood clotting.
