Fractures of the Elbow

These injuries are relatively common in both children and adults. In children, elbow fractures often occur due to falls while playing, while in adults they are frequently linked to sports injuries, accidents, or age-related bone weakness such as osteoporosis.

A fracture of the elbow refers to a break in one or more of the bones that form the elbow joint. The elbow is a complex hinge joint where the humerus (upper arm bone) meets the radius and ulna (two forearm bones). Because the elbow is crucial for bending, straightening, and rotating the forearm, any fracture in this area can significantly affect arm function. Elbow fractures can range from simple cracks in the bone to complex breaks that involve multiple fragments and the joint surface.

Anatomy of the Elbow

The elbow is formed by three bones:

  • Humerus – the long bone of the upper arm.
  • Ulna – the larger bone of the forearm, located on the side of the little finger.
  • Radius – the smaller forearm bone, located on the thumb side.

At the elbow joint, these bones are supported by ligaments, tendons, and muscles, which allow a combination of hinge (bending/straightening) and rotational (turning the palm up or down) movements. Because the elbow has a relatively thin layer of soft tissue covering it, the bones are vulnerable to direct trauma.

Causes of Elbow Fractures

Elbow fractures usually occur due to trauma or forceful impact. Some of the most common causes include:

  • Falls – Falling on an outstretched hand or directly onto the elbow is the most frequent cause.
  • Sports injuries – Contact sports, gymnastics, skating, cycling, and similar activities often lead to elbow fractures.
  • Motor vehicle accidents – High-energy trauma, such as from a car crash, can cause severe elbow fractures.
  • Direct blow – A direct impact to the elbow from a heavy object can result in a break.
  • Osteoporosis – In older adults, weakened bones increase the likelihood of fractures, even from minor falls.

Types of Elbow Fractures

Different bones and regions of the elbow can be affected, and fractures are classified accordingly:

1. Olecranon Fracture

Any part of your metacarpal can be fractured. Parts of your metacarpals include the:

  • Involves the bony prominence at the tip of the ulna (the part you feel when you touch your elbow).
  • Often occurs due to a fall directly onto the elbow.
  • Can be very painful and may prevent the person from straightening the arm.

2. Radial Head and Neck Fracture

Bennet and Rolando fractures are fractures that affect the joint at the base of your thumb metacarpal (the first metacarpal). They almost always require surgery.

  • The radial head (near the elbow joint on the thumb side) is commonly fractured when falling on an outstretched arm.
  • These fractures may cause difficulty rotating the forearm (turning the palm up or down).

3. Distal Humerus Fracture

  • Occurs in the lower end of the humerus where it connects with the elbow joint.
  • More common in older adults with osteoporosis and in children from high-impact injuries.
  • Often associated with complex joint involvement.

4. Supracondylar Fracture

  • A type of fracture just above the elbow joint in the humerus.
  • Very common in children, particularly when they fall on an outstretched arm.
  • Can be serious because it may affect blood vessels and nerves near the elbow.

5. Monteggia Fracture

  • A fracture of the ulna associated with dislocation of the radial head at the elbow joint.
  • Usually caused by falls or direct trauma.

6. Capitellum and Trochlea Fractures

  • Involve the rounded surfaces at the lower end of the humerus.
  • Less common but often intra-articular (extending into the joint), which can complicate treatment.

Symptoms of Elbow Fractures

The symptoms vary depending on the type and severity of the fracture but usually include:

  • Severe pain in the elbow, especially with movement.
  • Swelling and tenderness around the joint.
  • Bruising or discoloration.
  • Deformity of the elbow or arm.
  • Inability to bend or straighten the arm.
  • Difficulty in rotating the forearm.
  • Grinding or popping sensation when trying to move the elbow.
  • In severe cases, numbness, tingling, or weakness if nerves are affected.

Diagnosis

Doctors use a combination of physical examination and imaging tests to confirm an elbow fracture.

  • Physical exam – Checks for tenderness, swelling, deformity, and range of motion. Nerve and blood vessel function are also evaluated.
  • X-rays – The most common tool to detect fractures and assess displacement or angulation.
  • CT scan – Provides detailed images of complex fractures, especially those involving the joint.
  • MRI – Rarely needed but may help in evaluating soft tissue injuries around the elbow.

Treatment of Elbow Fractures

Treatment depends on the type of fracture, its severity, patient’s age, activity level, and presence of complications. The main goals are to restore bone alignment, allow healing, and preserve elbow function.

1. Non-Surgical Treatment

  • Immobilization – For simple, non-displaced fractures, the elbow is immobilized using a splint or cast for 3–6 weeks.
  • Pain management – Medications like NSAIDs help reduce pain and swelling.
  • Physical therapy – Once healing begins, exercises are introduced to regain movement and strength.

2. Surgical Treatment

  • Open Reduction and Internal Fixation (ORIF) – Plates, screws, or pins are used to realign and stabilize the bones.
  • External Fixation – In severe cases, an external frame may be applied to stabilize the fracture.
  • Joint replacement – In elderly patients with complex distal humerus fractures, elbow replacement may be considered.

Recovery and Rehabilitation

Recovery time varies depending on the type of fracture and treatment method:

  • Bone healing generally takes 6–12 weeks.
  • After immobilization, stiffness is common and requires physical therapy.
  • Rehabilitation includes gentle range-of-motion exercises, strengthening, and progressive return to daily activities.
  • Full recovery may take several months, and in some cases, patients may not regain complete movement, but most can achieve functional use of the arm.

Conclusion

Elbow fractures are common injuries that can significantly disrupt arm function. Because the elbow is a complex joint with essential roles in movement and daily activities, even a minor fracture requires careful attention. Understanding the different types of elbow fractures, recognizing symptoms, and seeking prompt medical care are crucial for optimal recovery. With modern treatment techniques and structured rehabilitation, most patients can regain strength, motion, and function, returning to their normal lifestyle after an elbow fracture.
