Hip Fractures
Epidemiology
■ 80% Women
■ 20-30% mortality risk in first year post fracture
Risk Factors
■ Osteoporosis/osteopenia
■ Diabetes mellitus
■ Recurrent falls
■ Tobacco and alcohol use
■ Caucasian
Treatment
Intracapsular Fracture
■ Dynamic Hip Screw
■ Hemiarthroplasty
■ Total Hip Arthroplasty
Extracapsular Fracture
■ Dynamic Hip Screw
■ Intramedullary nail
Complications
■ Osteoarthritis
■ Avascular necrosis of femoral head
■ Non-union
■ Mortality
■ Wound infection
■ Haematoma
What is the Classification for a Hip Fracture
Garden Classification of Intracapsular Hip Fractures
Garden I: Undisplaced, Incomplete fracture; Head has tilted into the valgus position
Garden II: Undisplaced, complete fracture
Garden III: Incompletely displaced complete fracture
Garden IV: Completely displaced complete fracture

What are the classifications for an Ankle Injury?
Pathophysiology of Compartment Syndrome?
Compartment syndrome results from increased pressure within a compartment, leading to compromised circulation.
Can occur acutely post-trauma or can be chronic, most often seen in athletes presenting with insidious pain
Risk Factors for Compartment Syndrome?
o Trauma: crush injury, long bone fracture
o Bleeding, hematoma
o Burn injury (especially circumferential burn)
o Prolonged extremity ischemia with reperfusion
o Intravenous extravasation injury
o High-pressure injection
Clinical Features of Compartment Syndrome?
o Pain – out of proportion to injury
o Tense firm compartment
o Pain exacerbated by passive stretch
o Compartment-specific neurovascular findings
o Compartment pressure within 30mmHg of diastolic BP
Treatment of Compartment Syndrome?
