Short Arm Cast
Avoiding Pressure Areas
"I Came, I Cast, I Cringed"
Every clinician remembers their first cast. Mine, however, is burned into memory with cinematic clarity. I began my journey as a new graduate at a major teaching hospital in Sydney. My earliest memory of casting still lives vividly in my mind. I was on a three-month secondment in a small rural hospital in southern New South Wales. The senior therapist there was… well, let’s just say, not exactly the nurturing, hand-holding type.
One day, she informed me that an 81-year-old lady was attending the fracture clinic with a fresh Colles’ fracture. “She needs a backslab,” she said flatly. “You’re doing it.”
No discussion. No “Have you ever done one before?” Just go do it.
Now, like many junior physios, my casting experience at that point was limited to theory and blind optimism. The task felt monumental, she may as well have told me to paint the Sistine Chapel ceiling. Start from the top, and by the way… there’s no ladder.
So, I did the cast. And oh, what a masterpiece of mediocrity it was. That poor woman, she’d already had a terrible day: first the fall, then the fracture, then the hours in emergency… and now, she was rewarded with a fresh accessory, a plaster brick, courtesy of me.
Strangely enough, later that day my senior colleague reported that the doctor had said, “Good job on that plaster.” Now, compliments from her were rarer than hen’s teeth, so I took it as genuine. But in hindsight, it probably said more about their benchmark for success than the quality of my craftsmanship.
From that day onward, I made a promise to myself, never again would I feel that sickening guilt of adding insult to injury (literally). I was determined to master the art of casting.
Years later, after running countless fracture and specialist clinics (a true baptism of fire), attending workshops, watching skilled colleagues, and occasionally fielding complaints, I can say with confidence that casting is a craft worth learning properly.
So, for those of you new to it, take heart. I’ve been in your shoes (and plastered stained clothes). Don’t be the one winging it and hoping for the best. Be the clinician who walks in, spots a dodgy cast from a mile away and reassures your patient:
“Let’s get you something better.”
Not only will you say it with confidence, you’ll mean it. And you’ll deliver.


The principles of fracture management are foundational concepts that guide the effective treatment of broken bones to ensure proper healing and function. These principles apply across most types of fractures, whether treated conservatively or surgically. The core principles are:
The limb must be positioned in anatomical or functional alignment
before and during casting.
Purpose: Ensures proper bone healing and joint function;
prevents malunion or stiffness.
Tip: Always check alignment visually and palpably before the cast sets.
Soft, even layers of padding are applied beneath the cast.
Purpose: Protects bony prominences, prevents pressure sores,
and allows for mild swelling.
Tip: Avoid wrinkles or uneven layers, these create
pressure points and discomfort.
The cast should be gently moulded using three-point pressure
principles to support fracture reduction.
Purpose: Maintains fracture alignment and stability.
Tip: Mould with the palms (not fingers) while the material
is still soft to create smooth contours.
Outer surfaces should be neat, even, and well-trimmed.
Purpose: Reduces snagging, improves durability, and
gives a professional appearance.
Tip: Fold back padding neatly at the edges and smooth
down any rough areas while setting.

The cast must be snug but not constrictive.
Purpose: Prevents movement that could displace the fracture, but allows adequate circulation.
Tip: Always check capillary refill and patient
comfort before discharge.
Joints should be immobilised in a functional position (e.g., wrist in slight extension, elbow at 90°, ankle at 90°).
Purpose: Optimises function during healing and minimises
post-cast stiffness.
Tip: Always consider the “position of safety”
for the region being casted.
Casts should extend only as far as necessary to immobilise
the fracture and adjacent joints.
Purpose: Provides stability without unnecessarily
restricting movement or causing pressure.
Tip: Check standard anatomical landmarks for each cast type
(e.g., below knee, above elbow).
The final and often most overlooked element.
Purpose: Ensures the patient understands cast care, warning signs (e.g. swelling, numbness), and follow-up needs.
Tip: A perfect cast technically means nothing if the patient is unsafe or anxious about managing it.
