Fractured Humerus Fixation
Humeral shaft fixation surgery is performed to stabilise a fracture in the middle portion of the upper arm bone (humerus) when the bone fragments are displaced or unstable. The procedure usually involves open reduction and internal fixation (ORIF) using plates and screws to realign the bone. Physiotherapy is essential after surgery to restore arm mobility, rebuild muscle strength, and help patients safely return to daily activities.
What is a Humeral Shaft Fracture?
The humerus is the long bone of the upper arm that connects the shoulder to the elbow. The shaft of the humerus refers to the long middle portion of this bone.
A humeral shaft fracture occurs when this section of the bone cracks or breaks due to trauma or excessive force. These fractures can cause significant pain, swelling, and difficulty using the arm.
While many humeral shaft fractures can be treated without surgery using a functional brace and sling, surgical fixation may be required when the bone fragments are displaced or cannot heal properly in their natural position.
How Does a Humeral Shaft Fracture Happen?
Humeral shaft fractures typically occur due to direct trauma or sudden impact to the arm.
Common causes include:
- Road traffic accidents
- Direct blows to the upper arm
- Sports injuries
- High-impact falls
- Falls from standing height in older adults
In younger individuals, these fractures are often caused by high-energy trauma, while in older adults they may occur after relatively minor falls due to reduced bone density.
What Are the Symptoms of a Humeral Shaft Fracture?
Symptoms usually appear immediately after the injury.
Common symptoms include:
- Severe pain in the upper arm
- Swelling and bruising around the arm
- Tenderness at the fracture site
- Difficulty moving the arm
- Weakness in the arm muscles
- Deformity in the upper arm in severe fractures
- Numbness or tingling in the arm if nearby nerves are affected
Because nerves run close to the humerus, some patients may experience temporary nerve-related symptoms.
What Should I Do If I Have a Humeral Shaft Fracture?
A suspected humeral shaft fracture requires urgent medical evaluation.
If this injury occurs:
- Avoid moving or using the injured arm
- Support the arm using a sling
- Apply ice wrapped in a cloth for 15–20 minutes to reduce swelling
- Seek immediate medical assessment at a hospital
Doctors will usually confirm the fracture using X-rays, and additional imaging such as CT scans may be used if required.
Many fractures are treated conservatively using a functional brace, but surgery may be necessary when the fracture is displaced.
Humeral Shaft Fixation Surgery
When surgical treatment is required, the most common procedure is Open Reduction and Internal Fixation (ORIF).
During this procedure:
- The surgeon makes an incision to access the fracture site.
- The broken bone fragments are realigned into their correct position.
- A metal plate and screws are used to stabilise the bone while it heals.
After surgery, the arm is usually supported with a functional brace or sling during the early recovery phase.
Physiotherapy Treatment for Humeral Shaft Fixation
Physiotherapy plays a vital role in restoring arm function after surgery.
At ACE Physio Sports in Singapore, physiotherapists design personalised rehabilitation programmes to help patients recover safely and regain full arm mobility.
Physiotherapy aims to:
- Reduce pain and swelling
- Restore shoulder and elbow mobility
- Strengthen muscles surrounding the arm
- Improve coordination and stability
- Restore independence in daily activities
Early Rehabilitation Phase
The initial phase focuses on protecting the surgical repair and managing symptoms.
Treatment may include:
- Pain management techniques
- Swelling control through elevation and gentle mobilisation
- Gentle range-of-motion exercises within safe limits
- Education on protecting the arm
- Guidance on safe daily activities
- Postural advice to reduce strain on the shoulder and arm
Middle Rehabilitation Phase
After several weeks, movement and strengthening exercises are gradually introduced.
Treatment may include:
- Gradual range-of-motion exercises for the shoulder, elbow, and wrist
- Gentle strengthening exercises for surrounding muscles
- Stretching exercises to maintain flexibility
- Functional training to restore daily activities
- Education on posture and safe arm movements
Advanced Rehabilitation Phase
As healing progresses, exercises become more functional and demanding.
Treatment may include:
- Functional strengthening exercises for the shoulder and arm
- Progressive resistance training
- Coordination and proprioception exercises
- Task-specific training for work or sports activities
- Core stability exercises to support upper limb function
Return to Activity Phase
During the final stage of rehabilitation, physiotherapy focuses on restoring full arm function and preventing future injury.
Treatment may include:
- Advanced strengthening exercises
- Functional movement training
- Sports-specific rehabilitation
- Fine motor coordination exercises
- Long-term injury prevention strategies
Most patients notice significant improvements in strength, flexibility, and functional ability as rehabilitation progresses.
What Should I Avoid After Humeral Shaft Fixation Surgery?
During recovery, patients should avoid activities that may interfere with healing.
Avoid the following:
- Lifting heavy objects in early recovery
- Sudden or uncontrolled arm movements
- Returning to sports too early
- Removing braces without medical advice
- Ignoring persistent pain or swelling
Following physiotherapy guidance ensures safe recovery and optimal results.
Can There Be Long-Term Effects?
Most humeral shaft fractures heal successfully with appropriate treatment and physiotherapy.
However, possible complications may include:
- Arm stiffness
- Muscle weakness
- Reduced shoulder or elbow mobility
- Nerve irritation
- Delayed bone healing
A structured rehabilitation programme significantly reduces the risk of long-term complications.

Frequently Asked Questions
How long before I can walk normally after Fractured Humerus Fixation?
This depends on the fracture site and type of fixation. Most patients begin partial weight-bearing within 6–12 weeks, guided by X-ray progress. Your physiotherapist will load the bone progressively once cleared by your surgeon — walking confidence usually follows within weeks of that milestone.
When should I start physiotherapy after Fractured Humerus Fixation?
Physiotherapy usually begins within 1–2 weeks post-surgery, focusing on gentle range-of-motion and swelling control. Strengthening begins once the fracture is sufficiently healed — typically 6–8 weeks — progressing toward full functional recovery.
What activities should I avoid after Fractured Humerus Fixation?
High-impact activities like running, jumping, and heavy lifting must be avoided until bone healing is confirmed on imaging. Your physiotherapist will guide a step-by-step return to activity, ensuring the bone is ready for every new load introduced.
