Arthroplasty: Joint reconstruction
Osteotomy: change bone alignment
Prosthesis: cemented, noncemented
When and why would an arthrodesis be done?
Definitions: Bones of joint fuse, no articular cartilage.
Pseudoarthrodesis: fibrous union
Bone MUST heal
Delay full ambulation
Use methylmetha-crylate (cement)
Cemented or non-porous coated prosthesis
No bone healing for cemented prosthesis
Porous-coated: allows for ingrowth ofbone
Assessment blood loss/wound
Knee replacement, patient guide
Normal and diseased knee joint
Components of knee joint: femoral, tibial (metal tray and plastic tray), patellar (button)
Porous-coated components needed for knee replacement
Identify post-op knee replacement patient care priorities!
Hip, Hip Hooray!
Causes of Falls
Shortened, externally rotated, flexed, abducted
Strong abductors displace
Blood supply determines healing!
What factors should your assess?
What is Priority?
ORIF: pins, plates, screws
Femoral head replacement
Maybe total joint replacement
Repair of Hip Fractures; ORIF or Prosthesis
Compare the nursing care of patient with joint prosthesis and Joint Replacement.
Types of Prosthesis
Intra-op considerations: approach, methylmethracrylate
Post-op Nursing Care:
Complications: blood loss
Potential dislocation: Prevent hip flexion, internal rotation
Preparing for Insertion of the Prosthesis
Total Hip Replacement
Total hip replacement, patient guide
Describe the surgical process of insertion of hip prosthesis.
Why is this called a total joint replacement?
Force hip more than 90 degrees
Force into adduction
No internal rotation
Put on own shoes, stockings for 8 wks
Use elevated toilet seat
Sleep with pillow between legs for 1st. 8 wks
Keep hip neutral
Use prophylactic antibiotics
