Olecranon fractures are injuries to the bony tip of the elbow, known as the olecranon, which forms the upper end of the ulna. The olecranon is the prominent point you can feel at the back of your elbow and serves as the attachment site for the triceps muscle, which straightens the elbow.
Olecranon fractures usually occur after a direct blow to the elbow or a fall onto a bent arm. Because the triceps attaches directly to the olecranon, fractures can disrupt the ability to straighten the elbow and significantly affect arm function.
Symptoms range from localised pain and swelling to complete loss of active elbow extension, depending on whether the fracture is displaced. Some fractures are stable and can be managed without surgery, while others require surgical fixation to restore elbow mechanics.
Physiotherapy for olecranon fractures is essential for restoring elbow movement, strength, and function after both non-operative and surgical management. Early, well-guided rehabilitation plays a key role in preventing long-term stiffness and weakness.
Key Facts
- Olecranon fractures account for approximately 10% of all elbow fractures and commonly result from direct trauma or falls. 🔗
- Displacement of the olecranon fracture often leads to loss of active elbow extension due to triceps disruption.
- Early controlled mobilisation following stable fixation is associated with improved elbow range of motion outcomes.
- Physiotherapy is recommended following olecranon fracture management to reduce stiffness and restore function.
Risk Factors
- Falls onto the elbow or a bent arm.
- Direct blows during contact sports or accidents.
- Reduced bone density (osteopenia or osteoporosis).
- Cycling or motor vehicle accidents.
- High-risk occupations involving falls or impacts.
Symptoms
- Pain and tenderness at the back of the elbow.
- Swelling and bruising around the elbow.
- Difficulty or inability to straighten the elbow.
- Pain with pushing, lifting, or weight-bearing through the arm.
- Visible deformity in displaced fractures.
- Reduced elbow range of motion as swelling develops.
Aggravating Factors
- Attempting to straighten the elbow against resistance.
- Pushing up from a chair or bed using the arms.
- Leaning on the elbow.
- Lifting or carrying objects.
- Accidental bumps to the back of the elbow.
Causes
Olecranon fractures usually occur due to direct trauma, such as falling onto the elbow or being struck by an object. They can also occur indirectly when a person falls and contracts the triceps forcefully to brace themselves, pulling the olecranon apart.
Because the triceps tendon inserts directly onto the olecranon, fractures are classified partly based on whether the extensor mechanism of the elbow remains intact. When the fracture is displaced, the triceps can no longer straighten the elbow effectively.
In older adults, lower-energy falls combined with reduced bone density can result in olecranon fractures. In younger individuals, higher-energy trauma such as contact sports, cycling accidents, or motor vehicle incidents are more common causes.
From a physiotherapy perspective, understanding fracture stability and fixation type is critical for determining how soon elbow movement and strengthening can safely begin.
How Is It Diagnosed?
Olecranon fractures are diagnosed using a combination of injury history, physical examination, and imaging. A clinician will suspect an olecranon fracture when there is pain and swelling at the back of the elbow after trauma, especially if elbow extension is limited.
On examination, there may be tenderness over the olecranon, swelling, bruising, and an inability to actively straighten the elbow against gravity. In displaced fractures, a palpable gap may be felt.
Physiotherapists play an important role in recognising possible fractures and referring promptly for imaging. Early diagnosis ensures appropriate immobilisation or surgical referral and prevents complications from delayed management.
Investigations & Imaging
- X-ray
- Primary imaging to confirm the presence, displacement, and pattern of the olecranon fracture.
- CT scan
- Used when fracture complexity needs further clarification or for surgical planning.
Grading / Classification
- Non-displaced fracture
- Fracture fragments remain aligned and the triceps mechanism is intact. Often managed non-operatively.
- Displaced fracture
- Fragments are separated and the triceps mechanism is disrupted, commonly requiring surgical fixation.
- Comminuted fracture
- The bone is broken into multiple pieces, often associated with higher-energy trauma.
Physiotherapy Management
Physiotherapy for olecranon fractures focuses on restoring elbow range of motion, rebuilding strength in the triceps and surrounding muscles, and guiding a safe return to daily activities, work, and sport.
The rehabilitation approach depends on whether the fracture was treated surgically or non-surgically, the stability of fixation, and the individual’s functional demands.
Exercise
Olecranon fracture physiotherapy exercises usually begin with gentle elbow range-of-motion exercises once cleared by the treating doctor or surgeon. Early movement is important to minimise stiffness, which is a common complication of elbow injuries.
As healing progresses, strengthening exercises for the triceps, forearm, and shoulder are introduced gradually. Load is progressed carefully to avoid stressing the healing fracture or fixation hardware.
Activity Modification
Activity modification is essential in the early stages. This may include avoiding pushing, lifting, pulling, or leaning through the affected arm.
Your physiotherapist will guide a graded return to work and sport tasks as strength and movement improve.
Manual Therapy
Manual therapy may be used to address elbow and forearm stiffness once fracture healing is sufficient. Techniques are applied cautiously to improve motion without compromising healing.
Heat & Ice
Ice can be used in the early stages to help manage pain and swelling. Heat may assist with stiffness later in rehabilitation when appropriate.
Education
Education is essential so patients understand healing timelines, safe movement limits, and why gradual progression is necessary to avoid complications.
Other
Other considerations may include workplace modifications, ergonomic advice, and coordination with employers or sporting organisations.
Other Treatments
Other treatments may include temporary immobilisation in a sling or splint, pain relief prescribed by a doctor, and follow-up imaging to monitor fracture healing.
Surgery
Surgery is commonly required for displaced olecranon fractures to restore elbow extension and joint congruency. Fixation methods include tension band wiring, plate fixation, or intramedullary devices.
Physiotherapy following surgery is critical to regain motion, strength, and function while respecting surgical precautions.
Prognosis & Return to Activity
The prognosis for olecranon fractures is generally good with appropriate management. Stable fractures treated conservatively and displaced fractures treated surgically often achieve good functional outcomes.
Elbow stiffness is the most common long-term issue, particularly if movement is delayed. Early, guided physiotherapy is key to optimising recovery.
Complications
- Elbow stiffness and reduced range of motion.
- Persistent weakness of elbow extension.
- Hardware irritation following surgical fixation.
- Post-traumatic arthritis in severe cases.
Preventing Recurrence
- Follow rehabilitation guidelines and avoid prolonged immobilisation when safe to move.
- Maintain upper limb strength and coordination to reduce fall risk.
- Address bone health and balance, particularly in older adults.
When to See a Physio
- You have elbow pain and swelling after a fall or direct impact.
- You cannot fully straighten your elbow.
- You have been diagnosed with an olecranon fracture and need rehabilitation guidance.
