Colles’ Fracture: Wrist Injury Causes, Symptoms, and First Aid Awareness
What is a Colles’ fracture?
A Colles’ fracture is a type of wrist fracture involving the radius, one of the two forearm bones. It occurs near the wrist joint and is most commonly caused by falling onto an outstretched hand. When this happens, the end of the radius breaks and shifts slightly backward toward the inner side of the wrist.
This injury is one of the most frequently seen wrist fractures and can affect people of all ages, particularly during falls on icy surfaces, sports activities, or workplace incidents.
Why Colles’ fractures matter in Canadian workplaces and daily life

-
Slips and falls, especially in winter conditions
-
Falls from ladders or steps
-
Recreational and workplace activities involving balance or speed
From a first aid and safety perspective, wrist injuries that limit movement or show visible deformity should not be ignored. Early recognition and appropriate response can reduce complications and support safer recovery and return to daily tasks.
Scenario: A common fall injury
While walking into a parking lot after work, an employee slipped on icy pavement and instinctively put their hand out to break the fall. Their wrist became swollen and painful within minutes. A coworker trained in first aid encouraged them to avoid using the hand, applied a cold pack, and helped arrange medical assessment. Imaging later confirmed a Colles’ fracture.
Common signs and symptoms
A Colles’ fracture often causes noticeable changes around the wrist and forearm, including:
-
Swelling in the wrist, hand, or lower arm
-
Pain that increases with movement
-
Bruising around the wrist
-
A visible bump or deformity near the wrist
-
Reduced ability to move or use the wrist and hand
Because these symptoms can overlap with severe sprains, imaging is usually required to confirm the injury.
Causes and mechanisms
The most common cause of a Colles’ fracture is a fall onto an outstretched hand, which transfers force directly to the wrist.
Contributing factors may include:
-
Slippery or uneven walking surfaces
-
Falls from height
-
Reduced bone strength due to age-related changes or bone conditions
The backward shift of the broken bone is a defining feature of this fracture pattern.
First aid awareness and general management
From a first aid and workplace awareness standpoint:
-
Suspected wrist fractures should be medically assessed promptly
-
The injured wrist should be supported and kept still
-
Cold packs can be used to help manage swelling while awaiting care
-
Rings, watches, or tight items should be removed early if swelling is present
Medical evaluation typically involves imaging to confirm the fracture and determine alignment. Management focuses on realigning the bone and keeping it immobilized so healing can occur.
Recovery and activity considerations
Colles’ fractures can temporarily limit daily activities such as writing, lifting, or typing. Gradual return of movement is often supported through guided rehabilitation once healing allows. Patience and adherence to medical guidance are important to restore strength and function safely.
Prevention and workplace considerations
Risk reduction strategies include:
-
Winter slip-and-fall prevention measures
-
Wearing appropriate footwear in icy conditions
-
Using handrails and ladders correctly
-
Encouraging early reporting of falls and near-misses
-
Providing first aid training that emphasizes limb support and injury recognition
Frequently Asked Questions
Why does a fall on the hand often break the wrist?
The wrist absorbs much of the force when someone falls forward, placing stress on the radius near the joint.
Is a Colles’ fracture the same as a wrist sprain?
No. A sprain involves ligaments, while a Colles’ fracture involves a break in the bone.
Can swelling appear quickly after the injury?
Yes. Swelling and pain often develop within minutes to hours after the fall.
Why is wrist immobilization important?
Keeping the wrist still helps protect the injured bone and supports proper healing.
Are Colles’ fractures common in winter?
Yes. Slippery conditions increase fall risk, making these fractures more common during Canadian winters.
