Indications

 

Poor soft tissues

- prohibit ORIF

 

Non union

 

Infected non uniion

 

Malunion / deformity

 

Bone loss / bone transport / LLD

 

Concept

 

Distal tibial allograft

Distal Tibial Allograft

 

Indication

 

Bony defects > 30 %

 

Options

- Latarjet - may be insufficient for lesions in the region of 50%

- Iliac crest - associated with high incidence of OA
- distal tibial allograft - radius of curvature matches glenoid highly

 

Platelet Rich Plasma

Definition

 

Platelet rich plasma

 

Concept

 

2 main components

 

1.  Platelets

- contain PDGF, TGF, VEGF

 

2.  Growth factors

- ILGF

- FGF

 

Formed from the separation of whole blood into plasma and RBC

- separation usually achieved with centrifugation
