ORTHOPEDIC TECHNOLOGIST UPDATED STUDY
EXAM GUIDE ALL QUESTIONS AND ANSWERS SURE
A+
✔✔Duputryen fracture - ✔✔spiral fracture of distal end of fibula - associated with ankle
diastasis
✔✔Dupuytren's disease/contracture - ✔✔"contracture of palmar fascia; dominant
genetic component most commonly European descent; affects ppl pulmonary disease,
alcoholism, diabetes, epilepsy
✔✔dye-punch fracture - ✔✔"intra-articular fracture of ulnar (volar) portion of distal
radius usually caused by direct impaction of the lunate onto lunate fossa of distal radius
"
✔✔Essex-Lopresti fracture - ✔✔comminuted radial head fracture with an injury to
central limb of forearm
✔✔Galeazzi fracture - ✔✔"""fracture of necessity"" - surgical fixation required -
displaced fracture of distal 1-1/3 or 1-1/4 of radius with disruption of distal radio-ulnar
joint "
, ✔✔Gamekeeper's thumb - ✔✔"injury involving the ulnar collateral ligament of the
thumb; rupture of UCL; hyperabduction injury with partial subluxation and instability of
the thumb MCP joint due to traumatic rupture of the UCL - also called skier's injury, due
to a ski-pole strap injury.
✔✔Gosselin fracture - ✔✔V -shaped fracture of the distal tibia into the tibiotalar joint
✔✔Henderson fracture - ✔✔trimalleolar fracture of the ankle
✔✔Hill Sachs fracture - ✔✔moderate compression fracture of humeral head (after GH
dislocation)
✔✔Hill Sachs lesion - ✔✔"seen on x-ray - an indentation of the posteromedial humeral
head, which occured at time of GH dislocation
✔✔Hoffa fracture - ✔✔coronal fracture of medial femoral ' condyle at knee
✔✔Humeral Fx <2cm short - ✔✔treat with a U-Shaped Co-aptation splint (not sling, not
long arm, not cylinder)
✔✔impacted fracture - ✔✔"fragments are compressed by force of original injury, driving
one fragment of bone into adjacent bone "
✔✔intra-trochanteric Fx - ✔✔"presents NWB with injured lower extremity markedly
shortened and externally rotated; caused by muscle forces pulling the fracture
proximally. Abductors tend to displace the lesser trochanter, while the hip flexors,
extensors and adductors pull the distal fragment proximally.
✔✔Jersey finger - ✔✔closed injury; rupture of the flexor digitorum profundus at its
insertion distal phalanx
✔✔Jones fracture - ✔✔fracture of base of 5th metatarsal - fx line extends from lateral
cortex in direction of proximal portion of articulation of the 4th/5th mets
✔✔Kienbock's disease - ✔✔involves lunate
✔✔Kohler fracture - ✔✔involves navicular (foot), seen in children - leads to avascular
necrosis
✔✔Lisfranc dislocation - ✔✔tarsometatarsal dislocation
✔✔Lisfranc fracture - ✔✔usually a fracture-dislocation with displacement of proximal
metatarsals
