TOTAL HIP REPLACEMENT
The hip joint is a type of ball and socket joint. The ball is formed by the head of the thigh bone (femur) and the socket is formed by part of the pelvis (acetabulum).Usually the surfaces of the bones are covered with a smooth coating (articular cartilage). This allows smooth, pain free movement in all directions.
Total Hip Replacement with Navigation
In Total Hip Replacement surgery, the damaged bone and cartilage is removed and replaced with prosthetic components. The damaged femoral head is removed and replaced with a metallic stem that is placed in to the hollow center of the femur. A metal or ceramic ball is placed on the upper part of the stem. The damaged cartilage surface of the socket (Acetabulum) is removed and replaced with metal socket to allow for a smooth gliding surface.
Types of Hip Replacement Implant
A joint is formed by the ends of 2 or more bones.
The hip must bear the full force of your weight and consists of two main parts:
- A ball (femoral head) at the top of your thigh bone (femur)
- A rounded socket (acetabulum) in your pelvis
What Causes Hip Joint Pain?
One of the most common causes of joint pain is arthritis.
The most common types of arthritis are due to:
- Osteoarthritis (OA)
- Rheumatoid Arthritis (RA)
- Post-traumatic Arthritis
- Avascular Necrosis
- Ankylosing spondylitis
Hip Surgery
May be suitable for patients who - Have a painful, disabling joint disease of the hip resulting from a severe form of arthritis - Are not likely to achieve satisfactory results from less invasive procedures, medication, physical therapy, or joint fluid supplements
Total Hip Replacement
- Socket is replaced by ceramic or metal cup
- Plastic liner is inserted between the cup and the ball to reduce wear
- Stem implant is inserted into femur
There is no age or weight restrictions for Hip replacement and is based on patient pain.
When is Surgery Recommended ?
- Hip pain that limits everyday activities like walking stairs, bending etc.
- Pain at rest – day or night
- Stiffness
- Inadequate relief from medication, physiotherapy and walking aids.
What is Computer-Assisted Surgery?
A technology that offers the ability to accurately align and improve the overall function of your new joint.
It provides interactive display of lines and measurements needed to give the your implant the best strength, stability and range of movement .
It allows the surgeon to make adjustments within a fraction of a degree helping to ensure the best possible fit for the implant
Hip Navigation
Navigation is a visual enabler for MIS Surgery
Technology and instrumentation enhances surgical procedure
More accurate placement of prosthesis
The potential benefits of MIS Hip Surgery with Navigation?
- Less soft tissue disruption –Faster discharge from the hospital –Quicker rehab and recovery
- Less blood loss
- Reduced pain
- Smaller scar
- May improve implant longevity
- Reduced dislocations
What are the potential risks?
- Results may vary from patient to patient
- Surgery time may be extended
- Risk factors relating to anatomy, weight, and prior joint replacements
- Risks which are normally encountered in conventional THA remain
Is Navigated MIS Total Hip Arthroplasty for everyone?
- No, patient limitations include:
- Obese, high BMI
- Muscular males
- Pre-existing conditions
- Osteoporotic bones
