Dislocated Elbow:
Symptoms, Causes and Treatments
A dislocated elbow occurs when the bones that form the elbow joint are forced out of their normal alignment, usually after a fall onto an outstretched hand or a high-impact injury. This sudden displacement can cause severe pain, visible deformity, swelling, and an inability to move the arm. Elbow dislocations are among the more common joint dislocations and frequently occur during sports activities or accidental falls. Prompt medical evaluation is important to assess joint stability and identify associated ligament, nerve, or vascular injuries.
Why It Happens
What Causes a Dislocated Elbow?
A dislocated elbow usually occurs when a significant force is transmitted through the arm, forcing the joint out of alignment. This most commonly happens during falls, direct trauma, or high-impact sports activities where the elbow is subjected to sudden twisting or impact:
Trauma
A fall onto an outstretched hand is one of the most common mechanisms of elbow dislocation. The force travels up the forearm to the elbow joint, disrupting its normal alignment. This is frequently seen in sports such as basketball, gymnastics, and contact activities.
Sports Injuries
High-impact or contact sports increase the risk of elbow dislocation due to collisions, falls, or awkward landings. Rapid changes in direction or forceful arm extension can place excessive stress on the joint and its supporting ligaments.
Motor Vehicle Accidents
Sudden deceleration or direct impact during a collision can transmit substantial force to the upper limb. The elbow may be forced out of position if the arm is braced against the dashboard, steering wheel, or ground during impact.
Falls
Falls from standing height or greater can generate enough force to dislocate the elbow, particularly when the individual instinctively extends the arm to break the fall. This is especially relevant in older adults, where balance issues increase fall risk.
Know Your Risk Profile
What Are the Risk Factors for a Dislocated Elbow?
While elbow dislocation is typically the result of acute trauma, certain factors can increase the likelihood of sustaining this injury. These risk factors relate to joint stability, activity level, and exposure to high-impact situations.
Participation in Contact or High-Risk Sports
Activities such as football, rugby, gymnastics, martial arts, or skateboarding increase exposure to falls and direct impact on the elbow.
Previous Elbow Injury
Prior ligament damage or a history of elbow instability may weaken joint support and increase the risk of recurrent dislocation.
Ligamentous Laxity (Joint Hypermobility)
Individuals with naturally looser ligaments may have reduced joint stability, making the elbow more susceptible to displacement during trauma.
High-Risk Occupations or Activities
Work or hobbies that involve climbing, heavy manual labour, or working at heights increase the likelihood of falls.
Younger Age Groups Involved in Sports
Children and adolescents engaged in high-energy physical activities may be at higher risk due to frequent falls and contact injuries.
What Are Common Symptoms of a Dislocated Elbow?
A dislocated elbow usually causes immediate and noticeable symptoms following an injury. The severity of these symptoms depends on the extent of joint displacement and whether surrounding structures are involved.
- Visible deformity of the elbow (the forearm may appear out of place)
- Intense pain in the elbow
- Swelling and bruising around the joint
- Limited range of motion or inability to straighten or bend the arm
- Numbness or tingling in the hand or fingers
Types of Elbow Dislocation
Elbow dislocations are generally classified into simple and complex types, depending on whether there are associated fractures or significant ligament injuries.
Simple Elbow Dislocation
A simple dislocation occurs when the elbow bones are displaced without fractures. Ligaments may be stretched, but overall stability remains. Treatment involves prompt reduction, short-term immobilisation (5 to 10 days) and early physiotherapy. Most patients regain functional motion within 4 to 6 weeks, though mild stiffness can persist initially.
Complex Elbow Dislocation
A complex elbow dislocation occurs when the joint is not only displaced but also associated with fractures of the surrounding bones. These may involve parts of the forearm or upper arm that form the elbow joint. Because both bone and ligament structures are injured, the joint is typically less stable and may require surgical treatment.
Understanding Your Evaluation
How Is Elbow Dislocation Diagnosed?
A dislocated elbow is identified through physical examination and confirmed via imaging to assess joint alignment and identify any associated bone or soft tissue injuries.
Physical Examination
Joint Alignment
The position of the elbow is assessed for visible deformity or abnormal angulation, which may indicate the direction and severity of dislocation.
Range of Motion
Movement is gently assessed to determine functional limitation and joint stability.
Swelling and Soft Tissue Injury
The extent of swelling, bruising, and tenderness is evaluated to assess ligament damage or associated trauma.
Neurovascular Assessment
Sensation, muscle function, and circulation are examined to ensure that nearby nerves and blood vessels have not been compromised.
X-rays
X-rays are the primary imaging tool used to confirm an elbow dislocation. They help determine the direction of joint displacement and assess whether the bones have shifted completely or partially out of alignment. X-rays are also essential for identifying associated fractures, which are common in complex dislocations and may influence treatment decisions.
CT scan and MRI
Advanced imaging may be recommended when more detail is required beyond what X-rays can provide.
CT Scan
A CT scan provides a more detailed view of the bone structures and is particularly useful in detecting subtle or complex fractures that may not be clearly visible on X-ray. It is often used in pre-operative planning to better understand fracture patterns.
MRI
MRI is used to evaluate soft tissue structures around the elbow, including ligaments, tendons, cartilage, and surrounding muscles. This is especially helpful when there is concern about significant ligament injury or persistent instability after reduction.
Exploring Treatment Options
Elbow Dislocation Treatments in Singapore
Treatment of an elbow dislocation focuses on promptly restoring joint alignment, ensuring stability, and preventing long-term stiffness or instability. The appropriate method depends on whether the dislocation is simple or associated with fractures or ligament injury.
Non-Surgical Treatments
Non-surgical management is appropriate for simple elbow dislocations where there are no associated fractures and the joint remains stable after reduction.
Closed Reduction
This involves gently manipulating the elbow back into its normal position under appropriate pain control or sedation. Prompt reduction helps relieve pain, restore circulation, and reduce the risk of complications.
Immobilisation
After reduction, the elbow may be placed in a splint or brace for a short period to allow the ligaments and soft tissues to heal. Prolonged immobilisation is avoided to minimise stiffness.
Early Controlled Mobilisation
Guided range-of-motion exercises are introduced once the joint is stable. Early movement helps reduce stiffness, improve circulation, and restore function while protecting healing ligaments.
Physiotherapy and Rehabilitation
A structured rehabilitation programme focuses on restoring strength, flexibility, and joint stability. Gradual strengthening of the surrounding muscles supports long-term recovery and reduces the risk of instability.
Surgical Treatments
Surgery may be required for complex elbow dislocations involving fractures, persistent joint instability after reduction, or recurrent dislocations. The surgical approach depends on the specific structures injured.
Ligament Repair or Reconstruction
If the stabilising ligaments of the elbow are severely torn, they may be surgically repaired or reconstructed to restore joint stability. This helps prevent chronic instability and recurrent dislocation.
Open Reduction and Internal Fixation (ORIF)
When fractures of the radial head, coronoid process, or distal humerus are present, the broken bone fragments may be repositioned and secured using screws or plates. Stabilising these fractures is key to restoring joint alignment and allowing for proper healing.
Radial Head Repair or Replacement
In cases of severe radial head fracture, the damaged portion may be repaired or, if not salvageable, replaced with a prosthetic implant to maintain elbow stability.
Joint Stabilisation Procedures
If the elbow remains unstable after repair, temporary stabilisation using internal fixation devices or external supports may be necessary to protect the joint during healing.
