Lower limb fractures - BULLSHIT DONT LEARN JUST DO NOF Flashcards
Types of femur fractures
- Shaft
- Distal
Shaft fracture clinical features
- Extreme pain
- Deformity
Types of shaft fractures
- Transverse type
- Oblique type
- Spiral type
Shaft fracture mechanism of injury (MOI)
- MC Motorcycle accidents
- Extremely high energy trauma to the lower limb
Distal fracture location
Fracture that occurs between:
- Distal diaphyseal-metaphyseal junction
- Articular surface of femoral condyles
Distal fracture MOI
- High-energy falls in young patients with significant displacement
- Elderly patients with osteoporosis, sustaining low-energy injuries
Distal fracture clinical features
Knee effusions may be present with inter-articular involvement
Types of knee fractures
Patella fracture
Patella fracture clinical features
- Inability to straight leg raise
- Tenderness of the knee cap
Patella fracture MOI
- Direct blow to the knee, e.g. dashboard injury
- Rapid contraction of the quadriceps against a flexed knee
Patella fracture DDx
Anatomical variant = bipartite patella = where individuals have 2 patella components in their knee
Types of tibia fractures
- Secgond fracture
- Tibial plateau fracture
- Tibial shaft fracture
- Toddler’s fracture
- Tibial plafond fracture
Segond fracture location
A small avulsion fracture at the lateral tibia plateau
- Assosciated with ACL injury in 75% of cases
Segond fracture MOI
Caused by internal rotation and varus stress
- Typically occur from sporting injuries
Tibial plateau fracture locations
Periarticular injuries of the proximal tibia
Tibial plateau MOI
- Varus or valgus injuries causing medial or lateral involvement respectively
- High energy impact in young individuals
Low-energy trauma in osteoporotic bone
Tibial shaft fracture clinical features
- Open fractures and compartment syndromes are common features
- This is due to the lack of fascial compartment and subcutaneous tissues of the shin
