Joint Replacement
Arthroplasty: Joint reconstruction
Osteotomy: change bone alignment
Prosthesis: cemented, noncemented
![Page 2: Joint Replacement n Arthroplasty: Joint reconstruction n Osteotomy: change bone alignment n Prosthesis: cemented, noncemented](https://reader035.vdocument.in/reader035/viewer/2022070306/5519c663550346b55b8b45c4/html5/thumbnails/2.jpg)
Arthrodesis
Definitions: Bones of joint fuse, no articular cartilage.
Pseudoarthrodesis: fibrous union
When and why would an arthrodesis be done?
![Page 3: Joint Replacement n Arthroplasty: Joint reconstruction n Osteotomy: change bone alignment n Prosthesis: cemented, noncemented](https://reader035.vdocument.in/reader035/viewer/2022070306/5519c663550346b55b8b45c4/html5/thumbnails/3.jpg)
Prosthesis
Porous coated– Non-cemented– Better fit– Bone MUST heal– Delay full
ambulation
Non-porous coated– Use
methylmetha-crylate (cement)
– Early ambulation

Cemented or non-porous coated prosthesis
No bone healing for cemented prosthesis

Porous-coated: allows for ingrowth of bone

Joint Replacement
Pre-op– Generally
elective– Assessment– Diagnostic work-
up– Teaching– Discharge
planning
Post-op– Anesthesia– Assessment blood
loss/wound – Blood admin.– Pain management– Prevent
complications

Hip, Hip Hooray!

Hip Fracture/Hip Replacement
Causes of Falls Hip anatomy
– Intracapsular– Extracapsular
Ligaments
Intracapsular– capital– subcapital– basilar– transcervical
Extracapsular– Shortened, externally
rotated, flexed, abducted– Strong abductors
displace– Intertrochanteric
![Page 18: Joint Replacement n Arthroplasty: Joint reconstruction n Osteotomy: change bone alignment n Prosthesis: cemented, noncemented](https://reader035.vdocument.in/reader035/viewer/2022070306/5519c663550346b55b8b45c4/html5/thumbnails/18.jpg)

Hip Fracture/Hip Replacement
Blood supply– Medial circumflex– Lateral circumflex– Fovealar
Blood supply determines healing!

Recognition Hip FracturesShortened, externally rotated, flexed, abductedStrong abductors displace!Pain, swelling, ecchymosis*Type fracture, displacement effect
![Page 21: Joint Replacement n Arthroplasty: Joint reconstruction n Osteotomy: change bone alignment n Prosthesis: cemented, noncemented](https://reader035.vdocument.in/reader035/viewer/2022070306/5519c663550346b55b8b45c4/html5/thumbnails/21.jpg)
Initial Assessment for Hip Fracture
What factors should your assess?
What is Priority?
Treatment Options:– ORIF: pins, plates,
screws– Femoral head
replacement– Maybe total joint
replacement Pre-op Care
![Page 22: Joint Replacement n Arthroplasty: Joint reconstruction n Osteotomy: change bone alignment n Prosthesis: cemented, noncemented](https://reader035.vdocument.in/reader035/viewer/2022070306/5519c663550346b55b8b45c4/html5/thumbnails/22.jpg)
Post-op Care: ORIF/Joint Replacement
Post-op ORIF– Blood loss– Pain– Positioning– Tissue perfusion– Complications– Exercise
![Page 23: Joint Replacement n Arthroplasty: Joint reconstruction n Osteotomy: change bone alignment n Prosthesis: cemented, noncemented](https://reader035.vdocument.in/reader035/viewer/2022070306/5519c663550346b55b8b45c4/html5/thumbnails/23.jpg)

and Joint Replacement.

Total Hip
Types of Prosthesis Pre-op Preparation Intra-op
considerations: approach, methylmethracrylate
Post-op Nursing Care:
– Complications: blood loss
– Neurovascular integrity
– Potential dislocation: Prevent hip flexion, internal rotation
– Weight bearing
– Prevent DVT
– Heterotrophic ossification
![Page 25: Joint Replacement n Arthroplasty: Joint reconstruction n Osteotomy: change bone alignment n Prosthesis: cemented, noncemented](https://reader035.vdocument.in/reader035/viewer/2022070306/5519c663550346b55b8b45c4/html5/thumbnails/25.jpg)

Describe the surgical process of insertion of hip prosthesis.

Critical Pathways!
Fx Hip/ORIF/Partial Hip Replacement
– Day 1 (ER): 0-4 hrs Eval& schedule surgery; pain control; assess; consults; tests; etc
– 4-23 hours– Day 2 )Post-op Day 1)– Day 3 (Post-op Day 2)– Day 4 (Post-op Day 3)– Day 5 (Post-op Day 4)– Discharge by 2 pm!

Why is this called a total joint replacement?
![Page 30: Joint Replacement n Arthroplasty: Joint reconstruction n Osteotomy: change bone alignment n Prosthesis: cemented, noncemented](https://reader035.vdocument.in/reader035/viewer/2022070306/5519c663550346b55b8b45c4/html5/thumbnails/30.jpg)
Keys to Care
Prevent dislocation! Progressive activity Prevent infection! Long term
considerations ? If little or no drainage post-op, what
to do?

Discharge Instructions Total Hip Do Not
– Force hip more than 90 degrees
– Force into adduction
– No internal rotation– Put on own shoes,
stockings for 8 wks
Do– Use elevated toilet
seat– Sleep with pillow
between legs for 1st. 8 wks
– Keep hip neutral– Use prophylactic
antibiotics– EXERCISE
