Healed Fracture Stage IV
Amputated 3rd distal phalanx
• Third digit was caught in a snow blower.
Amputated tuft of 1st digit
• The thumb was caught in an auger.
Soft tissue injury, with no bony involvement.
Dislocated 5th CM jt.
Dislocated 2nd DIP jt.
• This is a classic injury caused by catching a baseball.
• Note the avulsion fracture.
Dislocated Elbow
Dislocated Lunate
Dislocated 3rd PIP jt.
Dislocated 5th PIP jt.
• Monteggia fracture
Avulsion fracture
Boxers fracture
Colles fracture
Comminuted fracture of the tuft of the 3rd digit
Complete (Transverse) fracture
Spiral fractures
Obliquely oriented hairline fractures
Impacted fracture
Severe impaction
Navicular fracture
• The “waist” of the navicular is fractured.
• Note the difference in densities of the fracture fragments. This is caused by Aseptic necrosis.
Nightstick fracture
Open fracture
Radial head fracture
Radial head fracture
• This shows the importance of proper positioning.
• The partial flexion with the humerus parallel does not demonstrate the fracture.
Radial head fracture demonstrating the “fat pad sign”
Supracondylar fracture
Multiple forearm fractures
• Severely displaced fractures of the distal humerus radius, and ulna.
Severe soft tissue laceration
Pisiform fracture
Gaynor Hart
Greenstick fracture
“Bow” fracture
Note the cortical andimpactedfractures.
Torus fracture
Salter-Harris Type 1 fracture
• The type 1 fracture is indicated by a dislocation of the epiphysis.
Salter-Harris Type 2 fracture
• The type 2 fracture is indicated by a fracture of the metaphysis.
• Note the spiral fracture of the 2nd metacarpal.
Child Abuse
• This was a healing fracture that was re-broken.
• Note the periosteal callus formation (arrows).
Polydactyly
Multiple fractures & dislocations
Pre-op & Post-op joint replacement
Gunshot wound
2nd & 3rd digits nailed together
Fracture of the distal radius
• Fracture indicative of child abuse
Humeral Fracture
• Fracture indicative of child abuse
Gunshot wound
Ewings Sarcoma
