Upper limb injuries Flashcards
Clavivle fracture, where are the mrost common places?
Middle 1/3 (80%)
Lateral (12-15%), then Medial (5-6%)
hOW DO WE TREAT A BROKEN CLAVICLE? and when can we start mobilisation? In what circumstances would we do surgery?
You sling it (3-4 weeks)and strap it up. Most of the time you don’t need surgery.
Can start mobilisation after 2 weeks.
Surgery is only indicated when it is an open fracture, polytrauma, involving nerves, polytrauma, threatening the skin etc.
What do you see in acroio-clavicular injury?
Prominant clavicle bump
How do we treat acromioclavicular. injuries?
IId sprained, then sling, if dislocated then can do early fixation.
How do we trest the aillary nerve?
around the badge area, check sensation and ability to use the deltoid.
Why should we check the axillary nerve in acromioclavicular joint injuries?
Because if it is injured it wwill take longer to recover, as will need nerve to recover in order to use the deltoid muscle
What can’t you do with posterior dislocation? Would you have two?What is the most common fracture in an eldery patient?
externally rotate your arm (in comparrison to the other arm)
Dinner fork deformity=?
Colles fracture of the radius
Where does most scapoid fractures occur?

“Skiers thumb”
The classic caught in drymatt and pulled back all the way, meaning that you can sprain or pull off a bit of the bone.
It will obviously be painful if you try to pull back the thumb. On radial stress the joint will open -> can pop it under pressure to open up the joint and then see it on xray.
WHAT IS A BENNETT’S FRACTURE\/?
Base of thumb fracture. Think Lee bennet got into a scrap and broke the bone at the base of his thumb (the ulnar (medial part) split off). Actually mainly caused by proximal pull from the abductor pollicis longus. (forced ABDUCTION causes it)
Treatment of ennetts fracture?
It is an unstable fracture and so it needsreduction and then maintanence reduction (plaster cast/wire/screw fixation)
