intraoperative fracture

Arthroplasty

Indications

 

RA 

- very good results

- 97% 10 year survival Coonrad-Morrey prosthesis

 

Other Dx 

- OA / post-traumatic arthritis / nonunion

- tend to have worse survival than RA

 

Haemophilia

- elbow joint commonly involved

- 90% of haemophiliacs

 

Acute unreconstructable fracture > 60

 

Intra-operative fracture

THR Acetabular Fracture

 

Incidence

 

Increased incidence with press-fit component

- especially if under ream

 

Prevention

 

Don't under-ream >1mm

 

In osteopenic bone 

- line to line reaming

- i.e. ream to outer diameter of cup

 

This also avoids leaving gaps at floor 

- very common if under-ream by 2mm
