Distal humerus fracture

A distal humerus fracture is a break in the lower end of the upper arm bone (humerus) where it forms the top part of the elbow joint.

Distal humerus fracture overview

The distal humerus is the lower portion of the upper arm bone that creates the bony points felt on the inside and outside of your elbow, running just above the ulnar nerve (often referred to as the ‘funny bone’). Although fairly unusual, fractures in this area are serious injuries because they directly affect the alignment and movement of the elbow joint. These fractures are typically caused by a direct blow to the elbow, such as a fall onto a hard surface or an impact during sports, or by falling onto an outstretched arm with the elbow locked, which drives the forearm bone (ulna) forcefully into the humerus. Prompt specialist assessment is essential to restore joint stability and preserve full long-term function.

Common symptoms include:

Severe, immediate pain in the upper arm and elbow

Swelling and extensive bruising around the joint

Stiffness and inability to bend or straighten the arm

A feeling of instability or weakness in the elbow

Visible deformity, or in rare cases, an open fracture where the bone has pierced the skin

 

How is a distal humerus fracture diagnosed?

Diagnosing a distal humerus fracture involves a thorough physical evaluation by your consultant to check for bone displacement, joint stability, and any nerve or blood vessel involvement.

X-rays will be taken to confirm the diagnosis and assess the pattern of the break. In complex cases, a CT scan may also be used to provide detailed 3D images of the bone fragments.

 

Are there any risks?

Complications can occur following a distal humerus fracture or its repair. Potential risks include:

  • Irritation or damage to nearby nerves (particularly the ulnar nerve), leading to numbness or weakness in the hand and fingers
  • Joint stiffness or permanent reduction in elbow range of motion
  • Infection around the surgical site or internal hardware
  • Delayed healing or failure of the bone to unite (non-union)
  • Post-traumatic arthritis in the elbow joint
  • The need for further surgery to remove hardware or release scar tissue

Your specialist will discuss all potential risks with you in detail prior to treatment.

Recovery from a distal humerus fracture

0–2 weeks

Rest and immobilisation

Your arm will be protected in a cast, splint, or post-operative dressing. Focus on keeping your arm elevated to reduce swelling and keeping dressings clean and dry. Gently moving your fingers and shoulder (if comfortable) helps prevent stiffness.

2–6 weeks

Controlled movement

Your specialist will review your progress, remove any stitches, and take follow-up X-rays to check bone healing. You will usually transition to a removable brace and begin gentle, non-weight-bearing range-of-motion exercises guided by your physiotherapist.

6–12 weeks

Progressive rehabilitation

As the bone continues to consolidate, you will begin light strengthening exercises and gradually increase daily use of the arm. Most light non-manual tasks can be resumed during this phase.

3–6 months

Advanced recovery and strength

Rehabilitation focuses on restoring full functional strength and maximum range of motion. Heavy lifting, manual work, and contact sports are gradually reintroduced as guided by your consultant.

Working with elbow professionals and teams

Our elbow specialists support professional athletes, sports teams, active individuals and people whose work places high demands on their elbows. Working closely with radiologists, physiotherapists and the wider multidisciplinary team, they provide coordinated care from diagnosis through to rehabilitation, helping each person return safely to sport, work or everyday activities.

 

The same specialist expertise and collaborative approach are available to every patient, whatever your activity level or recovery goals.
