Total hip replacement

• Is it the right

answer?

• Yes!!
• When to pull the

plug???

• All the time!!

The older active individual with a displaced fracture

• No brainer
• THA give the best
• utcomes
• Less pain and

reoperations

• Vastly superior to internal

fixation

How young is too young for THA

• A cost-effective option for a displaced

femoral neck fracture in an:

– Otherwise healthy patient who is >54 years

• ld

– A patient with mild comorbidity who is >47 years old – A patient with multiple comorbidities who is >44 years old.

How non-active is too non- active for THA

• Dementia
• Low life expectancy
• Do not ambulate without

walker

• Pull the plug but do a hemi

Displacement

• Data suggest that patients are more

satisfied with THA than fixation

• Can weightbear as tolerated and not worry

about fracture healing

• No late osteonecrosis or shortening

Tips for THA in fracture patients

• Avoid

– Fracture – Dislocation

• Consider

– Approach – Stem type – Surgeon

Periprosthetic fractures

• Norwegian hip fracture registry

5 year survival

• Uncemented stems 91%
• Cemented stems 97%
• Cemented stem lower reoperation rates

Use a cemented stem

• Reliable

– Cement embolization – Intra-operative hypotension – 26 of 8639 patients in Norwegian hip fracture registry

Be prepared for intraoperative fractures

• Look for calcar cracks
• Cable if found
• Consider strongly

cemented stem

• Be very careful with anterior

approach

Acetabular side

• Careful with reaming and cup impaction
• Do not break the acetabulum either
• Low threshold for additional screws

THA dislocation risk

• Much higher in hip fracture

population: 8% ?? Non expert surgeons

• r

Laxity of capsule in non- arthritic hip

Prevent dislocation

• Proper anteversion of stem
• Correct acetabular

positioning

Prevent dislocation

• Anterolateral approach has less

dislocation

• Consider its use particularly in patients at

high risk of dislocation

• Repair the capsule if you do posterior

approach

Prevent dislocation

• Use the largest head available
• Consider the use of a dual mobility type

head to give the biggest size available

The surgeon: When and who should pull it

• Hip fractures do best with surgery as

quickly as possible

• If you are on call and never do a THA you

will need to get someone who does to do the surgery

Conclusion: Pull the plug!

• Total hip replacement less

pain and better outcomes in several randomized studies

• THA for active patients

– Live alone – Under 80 – No ambulatory aids

Technique is important

Reduce fracture risk cement the stem Reduce dislocation risk correct position large head anterolateral approach Early surgery with the best surgeon

Thank You
