Humeral Shaft Fracture (Mid-Arm Fracture)

What is a Humeral Shaft Fracture?

A humeral shaft fracture occurs in the middle portion of the upper arm bone between the shoulder and elbow.

These injuries often result from:

  • Falls
  • Motor vehicle accidents
  • Sports injuries
  • Direct trauma to the arm

Symptoms

Common symptoms include:

  • Pain in the upper arm
  • Swelling and bruising
  • Difficulty moving the arm
  • Arm deformity in some cases

Occasionally, a nearby nerve called the radial nerve can be affected, causing temporary weakness or numbness in the hand.

Treatment

Many humeral shaft fractures heal successfully without surgery.

Non-surgical treatment may include:

  • Splint or sling initially
  • Functional bracing
  • Gradual range-of-motion exercises

Surgery may be recommended for fractures that are severely displaced or fail to heal properly. Surgical options include plate fixation or intramedullary nailing.

Recovery

Bone healing typically occurs within 8–12 weeks, followed by strengthening and motion exercises.
