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
