Q

What is Thompson test and what is its significance?

A

Ask the patient to lie prone with their feet dangling over the edge of bed.
Gently squeeze the calf muscle.
Normal response is plantar flexion. Absence of plantar flexion upon squeezing the calf muscle is positive for THOMPSON TEST.
It is present in achilles tendon rupture

Q

Differentiate Colles fracture from Smith fracture.

A

Both Colles and Smith fracture are both fracture of the distal radius.
Colles = dinner fork deformity = distal radius is posteriorly displaced
Smith = garden spade deformity = reverse Colles = distal radius is anteriorly displaced

*** Si P Diddy ay may Colles (PD - posteriorly displaced, D - dinner fork deformity; Colles)
Si Smith ay may member ng ADG, nagpapractice sa garden. (ADG - anteriorly displaced; garden spade deformity; Smith fracture)
