LE Joint Replacements & Frac

purpose of joint replacements

provide viable surfaces that articulate in a manner close to normal

restore movement at the joint for function

reduce/eliminate pain

repair fractured bones through removal & replacement

Joint replacement terminology

THR, THA, TKR, TKA, Hemiarthroplasty

THR- total hip replacement

THA- total hip arthroplasty

TKR- total knee replacement

TKA- total knee arthroplasty

Hemiarthroplasty- replacement of only the femoral or humeral head

standard precautions for THA & Hemiarthroplasty

posterior precautions:

• no hip flexion > 90degrees

• no IR

• no adduction past midline

anterior precautions:

• no ER

• no adduction past midline

• no extension

restrictions: LE weight bearing THA/TKA

cemented joint replacements: weight bear as tolerated unless operative procedure involved a soft-tissue repair or internal fixation of bone

cementless, or ingrowth, joint replacements: partial weight bearing or toe-touch weight bearing

what is the leading cause of fractures?

trauma

non-surgical management for fractures

closed reduction- manually align

• cast or splint

surgical management for fractures

ORIF- open reduction internal fixation

3 phases of fracture healing

phase 1- 0 to 2 wks

• prior to stabilization or clinical healing

phase 2- 2 to 8 wks

• fracture site is stable

phase 3- 6+ wks

• fracture is healed

• varies greatly from person to person

  • confirmed by x-rays— physician report
