CHT practice exam questions and answers 2026\2027 A+
Grade
Frykman Classification of Distal Radius Fractures
- correct answer Type 1: Extra articular
Type 2: Type 1 + distal ulna
Type 3: Intra-articular - radiocarpal
Type 4: Type 3 + distal ulna
Type 5: Intra-articular - DRUJ
Type 6: Type 5 + distal ulna
Type 7: radiocarpal + DRUJ
Type 8: Type 7 + distal ulna
AO system is also commonly used for DR fracture classification
extraarticular fractures are what percent of fractures?
- correct answer 85%
at 3 weeks post-op, an incised surgical wound tensile strength
- correct answer only 15%
creep
- correct answer physiological response of tissue to applied force
initially becomes tense then gradually expands
Pyogenic granuloma
- correct answer Pyogenic granuloma is a relatively common, reactive proliferation of capillary blood
, vessels. It presents as a shiny red lump with a raspberry-like or minced meat-like surface. Although they
are benign, pyogenic granulomas can cause discomfort and profuse bleeding.
formulation of granulation tissue on surface of skin due to low rate infection or foreign body
can treat with silver nitrate
trampoline test
- correct answer subjective assessment of integrity of TFCC during scope
Poppen's Ridge Test
- correct answer Device with ridges applied parallel to longitudinal axis of finger and moved in a
proximal to distal direction at a rate of 1 cm/sec and patient is to say "now" when the surface does not
feel smooth as the device is applied. The calibration level marked on the ridge device is noted on the
sensory evaluation form.
Normal = 0-1 cm
Equal to or less than 10 mm 2 Point Discrimination = 1-2 cm
Greater than 8 mm 2 point discrimination = inability to feel ridge device
Because it is a moving test it detects presence or absence of tactile gnosis (stereognosis)
Ecchymosis
- correct answer bruise
discoloration of skin by hemorrhaging of tiny blood vessels
A primary bone tumor of the hand occurs in what percentage of hand and wrist bone tumors?
- correct answer 5%
Wafer procedure
- correct answer The arthroscopic wafer procedure involves debridement of the central triangular
fibrocartilage complex tear, along with debridement of the distal pole of the ulna causing the impaction.
Debridement of the ulna arthroscopically is taken down to a level at which the patient is ulnar neutral or
slightly ulnar negative
