Guide management
Systematic Approach of an X-ray/Plain radiography
Check patients details → name, side of body, date of xray
Consider clinical info → why do they require an x-ray?
Look at all images available → more than one view/compare
Bone and joint alignment → subluxation, dislocation, fracture
Bone cortex, texture & cortical outline → cortex = whiter
Joint spacing → degeneration
Soft tissue structures → swelling, joint effusion, myositis ossificans
ABCS → Alignment, Bone, Cartilage, Soft tissue
Advantages & Disadvantages of Computed Tomography (CT)
Advantages:
Evaluation of bone and calcification
Can be reconstructed into 3D images
Disadvantages:

What are 3 major causes of limb amputation? Pvd D T
Peripheral Vascular Disease
Diabetes
Trauma
What are the 3 amputation types?
Primary → performed as the initial treatment, usually when a limb is severely damaged or diseased (e.g. poor blood supply or infection) and cannot be saved
Secondary → after attempts to preserve the limb have failed (e.g. after surgery or treatment complications), so the limb is removed at a later stage.
Traumatic → Occurs at time of injury
Transtibial Amputation (TTA) technique
Most common = Burgess technique
Posterior flap is made from lateral and medial gastrocnemius and some soleus muscle
Flap fixed anteriorly by sutures
Also referred to as “Below Knee Amputation” (BKA)

Myopexy of posteromedial musculature to shape stump
Scar line sits at the base of the stump
Also referred to as “Above Knee Amputation” (AKA)

2 Advantages & 2 Disadvantages of Removable Rigid Dressings (RRD) in stump care
Advantages → Reduced oedema and shapes the stump
Disadvantages → Can be heavy & specialist required for application
Needs to be applied in theatre and to be worn for up to 2 weeks (progress to shrinker socks)
2 Advantages & 2 Disadvantages of Bandaging/shrinker socks in stump care
Advantages → Washable and easy to don/doff
Disadvantages → May slip off and slower healing
Bandaging → 2-4 days post-op once wound dressings are minimized and pain allows
Shrinker socks → 7-10 days when conical shape is forming
Bandaging guidelines for Stumps/amputations
Check stump first, dressing over wound
All bandage turns should be diagonal (not spiral) to avoid tourniquet (figure 8 dressing)
Never restrict blood flow = reduced circulation
Should be applied with extended knee
Graduated pressure, firm at end of stump, apply pressure on upwards turns.
Re-apply every 4 hr
No folds, creases, windows
No pins to secure, use only tape
Worn 24/7
