TEXT
WHY SHOULD WE KNOW ABOUT THESE FRACTURES
▸ THESE ARE SOME OF THE MOST COMMON FRACTURES SEEN
▸ THEY ARE ALSO SOME OF THE MOST EASILY MISSED
▸ CAN LEAD TO SIGNIFICANT DISABILITY IF UNTREATED
▸ VERY EASY TO IDENTIFY ONCE YOU KNOW WHAT TO LOOK FOR

THE ZONE OF VULNERABILITY
MOST FRACTURES/DISLOCATIONS WILL OCCUR HERE
▸ MOST INJURIES ARE DUE TO FOOSH (FALL ON OUT STRETCHED HAND)
▸ AS YOU PROGRESS FROM RADIUS TO ULNAR SIDE, THE SEVERITY OF INJURY INCREASES BUT THE FREQUENCY DECREASES
▸ I.E, A RADIAL STYLOID # IS COMMON BUT NOT SEVERE
▸ AN ULNAR STYLOID FRACTURE IS LESS COMMON BUT MORE SEVERE
▸ A SCAPHOID WAIST # IS MORE COMMON THAN A HAMATE #, BUT THE HAMATE # IS A MORE SEVERE INJURY (GOT IT?!)
▸ THIS APPLIES TO DISLOCATIONS/ FRACTURE-DISLOCATIONS AS WELL

FIND THE FRACTURE
WAS IT DIFFICULT?
▸ HOW COMMON IS IT?
▸ HOW SEVERE IS IT?

LETS TRY SOME CARPAL BONE #’S

FIND THE FRACTURE
WHAT IS IT CALLED?
▸ HOW COMMON IS IT
▸ HOW SEVERE IS IT
▸ WHAT IS THE DANGER OF THIS #

FIND THE FRACTURE
WAS IT DIFFICULT?
▸ THESE FRACTURES CAN BE SUBTLE
▸ CHECK FOR PAIN IN THE ANATOMICAL SNUFFBOX
▸ IF YOU ARE UNSURE THEN BETTER TO PUT IN A POP AND RE X-RAY IN 10-14 DAYS

LETS DO SOME DISLOCATIONS
![Page 24: Wrist fractures pdf](https://reader034.vdocument.in/reader034/viewer/2022050614/58eced311a28ab06668b45ef/html5/thumbnails/24.jpg)
A NORMAL LATERAL
VERY IMPORTANT FOR ASSESSING DISLOCATIONS
▸ CAN YOU NAME WHAT YOU SEE?
▸ C- CAPITATE , SITS IN THE L-LUNATE, SITS IN THE R-RADIUS
▸ APPLE (C) SITS IN THE CUP (L) SITS IN THE SAUCER (R)
C
L
R

WHAT IS OUT OF PLACE?
COMPARE TO THE PREVIOUS IMAGE
![Page 26: Wrist fractures pdf](https://reader034.vdocument.in/reader034/viewer/2022050614/58eced311a28ab06668b45ef/html5/thumbnails/26.jpg)
CAN YOU SEE IT NOW
THIS IS A LUNATE DISLOCATION
▸ THE LUNATE (CUP) IS DISPLACED FROM THE RADIUS (SAUCER)
▸ THE CAPITATE MAY BE IN VARIOUS POSITIONS BUT IS GENERALLY POSTERIOR
![Page 27: Wrist fractures pdf](https://reader034.vdocument.in/reader034/viewer/2022050614/58eced311a28ab06668b45ef/html5/thumbnails/27.jpg)
WHAT IS OUT OF PLACE?
THINK OF THE APPLE, CUP AND SAUCER
![Page 28: Wrist fractures pdf](https://reader034.vdocument.in/reader034/viewer/2022050614/58eced311a28ab06668b45ef/html5/thumbnails/28.jpg)
CAN YOU SEE IT NOW?
THIS IS A PERILUNATE DISLOCATION
▸ THE CAPITATE (APPLE) HAS DISLOCATED FROM THE LUNATE (CUP)
▸ BUT THE LUNATE (CUP) IS STILL ATTACHED TO THE RADIUS (SAUCER)
▸ EASY?
![Page 29: Wrist fractures pdf](https://reader034.vdocument.in/reader034/viewer/2022050614/58eced311a28ab06668b45ef/html5/thumbnails/29.jpg)
THE DIAGNOSIS IS NOT IMPORTANT
CAN YOU SEE THE DISPLACEMENTS
![Page 30: Wrist fractures pdf](https://reader034.vdocument.in/reader034/viewer/2022050614/58eced311a28ab06668b45ef/html5/thumbnails/30.jpg)
NOT SO DIFFICULT IS IT!
THIS IS A MIDCARPAL DISLOCATION
▸ BOTH THE CAPITATE AND LUNATE ARE DISPLACED
▸ THE MOST IMPORTANT THING IS TO SPOT THE DISPLACEMENT, THE FINAL DIAGNOSIS IS MADE BY AN ORTHOPAEDIC SPECIALIST
▸ BUT THEY WILL BE IMPRESSED IF YOU PICK IT UP
![Page 31: Wrist fractures pdf](https://reader034.vdocument.in/reader034/viewer/2022050614/58eced311a28ab06668b45ef/html5/thumbnails/31.jpg)
FINALLY
THIS IS A SCAPHO-LUNATE DISSOCIATION
▸ NOTE THE WIDE SPACE BETWEEN THE SCAPHOID AND THE LUNATE
▸ CAUSES AN UNSTABLE WRIST
▸ VERY EASY TO MISS
▸ SEVERE PAIN ON MOVEMENT IN THE ABSENCE OF A # SHOULD MAKE YOU GO BACK AND CHECK FOR THIS
