Hand Injuries Flashcards
Why is the nail so important
To preserve the soft tissue and acts as a splint
Describe a Boxers fracture
Minimal displacement
No rotation
More distal
What is the treatment / management for a Boxer’s fracture
Buddy strap and early mobilisation
What do we do if there is an angular deformity
Usually requires surgery as it is very unstable
What finger is usually affected by Mallet Finger
Middle finger
How does Mallet finger occur
Often basketball
When the finger has been forcibly flexed – either gone through the tendon or possibly a bit of bone has been pulled off
What is the management for Mallet finger
A mallet splint for 6 weeks that is to be worn 24/7
What is the management/ treatment for a PIP joint dislocation
Pull to reduce (local anaesthetic)
Buddy strap
What is the treatment for a PIP joint dislocation that is late in presenting
Fixation / stabilisation
What does a Bennett’s fracture involve
The whole of the metacarpal moving away
What is the treatment for a Bennett’s fracture
Wires or screws need to be put in
Bennett’s fracture is a benign injury. True or False
False
How can we test the FDS tendon
Hold other fingers straight and bend the one that you are testing
What does the FDS tendon do?
flexor of fingers (primarily at proximal interphalangeal joints)
What is the function of the FDP tendon
flex hand and both interphalangeal joints
How can the FDP tendon be tested
isolated testing of the FDP is performed by having middle phalanx held in full extension by the examiner;
- distal phalanx is then actively flexed;
- test is best performed by maximally extending wrist and MP joints;
- ie, examiner's holding all finger joints in extension except distal joint;
What is the management for an injured flexor tendon
Surgery - need to protext the repair whilst still moving the fingers - splint stop fingers from over extending
What are some of the principles of mutilating injuries
Preserve amputated parts on ice Early debridement Establish bony support Establish vascularity Repair all tissues Establish skin cover Prevent / treat infection Aggressive mobilisation
What is the standard treatment for burns
Respiratory function
Infection prevention
Hydrate
Pain relief
What is Eschar
Thick, leathery, inelastic skin which can form after burns
What might Eschar require
Surgical release to allow movement
