Carpal Bones
A groove formed by the fusion of the proximal and distal row of the carpal bones - ANS-What is
the carpal groove?
Scaphoid, lunate, triquetrum, and pisiform - ANS-What bones are found in the proximal row?
Scaphoid - ANS-What is the largest bone of the proximal row?
Trapezium, trapezoid, capitate, and hamate - ANS-What bones are found in the distal row?
Trapezium - ANS-What is the largest bone of the distal row?
Fractures of the carpal bones - ANS-What is the most common fracture of the skeletal system?
Scaphoid, followed by triquetrum - ANS-What carpal bone is the most commonly fractured?
Tendons, several muscles, and median nerve - ANS-What are the contents of the carpal
groove?
It is formed by the covering of the flexor retinaculum over the carpal groove - ANS-What is the
carpal tunnel?
Tendons of some flexor muscles of the hand and wrist and the median nerve - ANS-What are
the contents of the carpal tunnel?
Pain and weakness of the hands caused by compression of median nerve in the carpal tunnel -
ANS-What is carpal tunnel syndrome?
Repetitive movement of the wrist, such as typing - ANS-What is the most common cause of
carpal tunnel syndrome?
local steroid injection, splinting, or surgery to divide the flexor retinaculum - ANS-What are
common treatments for carpal tunnel syndrome?
Hypothyroidism - ANS-What else can lead to carpal tunnel syndrome?
Muscle that covers the carpal bones dorsally and has six compartments - ANS-What is the
extensor retinaculum?
Abductor Pollicis Longus and Extensor Pollicis Brevis - ANS-What are the contents of the 1st
compartment of the extensor retinaculum?
