Study Notes
Total Hip Replacement: Key Points
- Total Hip Replacement (THR) aims to relieve pain, improve or maintain range of motion, and correct deformity.
- Conditions leading to the need for THR include osteoarthritis, avascular necrosis, dislocations, and femoral neck fractures.
- THR involves replacing the hip joint with prosthetic components, including a metal ball, stem, and socket with a plastic lining.
- Implant materials commonly used in THR include stainless steel, metal alloys, and durable polyethylene.
- The decision to use cemented or non-cemented components depends on factors such as bone quality and strength.
- The anterior approach for THR offers advantages such as less muscle damage, reduced post-operative pain, faster recovery, and decreased risk of dislocation.
- Potential disadvantages of the anterior approach include technical challenges and potential for nerve damage.
- Minimally invasive techniques for THR involve shorter surgical incisions, typically around 4 inches or less.
- Posterior approach THR requires specific hip precautions to avoid dislocation, including limiting rotation and flexion of the hip.
- Measures such as abduction pillows and wedge cushions are used post-operatively to maintain hip alignment and prevent dislocation.
- Patients are advised to avoid certain movements post-operatively, such as crossing legs, bending beyond 90 degrees, and using reachers for tasks like picking up items from the floor.
- Specific toileting techniques, such as using a regular or fracture bedpan, and dressing the operated leg first, are recommended to ensure precautions are maintained post-operatively.
