Femur Anatomy:
- Femoral head blood supply is retrograde -> higher risk of AVN. (As well as talus and scaphoid)
Hip Fractures:
Garden Classification Of Femoral Neck Fractures:
- Type I: partial, non-displaced, valgus impacted
- Type II: complete, non-displaced
- Type II: complete, partially displaced, varus
- Type IV: complete, fully displaced, varus
Complications:
- AVN: most commonly due to disruption of the medial circumflex artery (the deep branch, specifically). Higher risk in femoral neck fractures (especially if sub-capital)
- Non-union
- DVT
- Infection
