27 Sep TOTAL HIP REPLACEMENT(THR)
Aims of THR
- Hip centre of rotation restoration
- limb length correction
- correct offset and abductor tension
- component positioning to be done properly.
Implant of choice
- Depends on patients age, amount of deformity, amount of bone loss, any under lying disease or comorbidity.
- either cemented or uncemented
Templating
- Helps favourable implant selection and sizing for better biomechanics anatomical placement of implant.
- Reduce limb length discrepancy
- To look at any anatomical anomalies and potential complication
- Guide to neck cuts
Navigation
- Computer assisted surgery
- Little evidence that outcome are improved through use of navigation
- Accuracy may be affected in large patient.
Approach
Minimally invasive THR have not reproduced additional benefit in long term studies.
