Elbow Fracture and Dislocation: Signs and How They Are Distinguished

A blow to the elbow area or a fall onto an outstretched arm almost always leaves you at a loss: the pain is severe, the arm won't obey, and what exactly is damaged — bone, joint, or only soft tissue — cannot be understood from appearance. Below is a calm breakdown of the signs of an elbow fracture and elbow joint dislocation, without panic and without promises of a quick miracle.

What an elbow fracture is and how the elbow joint is structured

The elbow joint is a complex connection: the humerus articulates with the ulna and radius, all held by the capsule and collateral ligaments. An elbow fracture is a break in the integrity of one of these bones. With a fracture of the arm or wrist, the limb suddenly becomes painful, swells, a bruise appears, and it is difficult to move the arm; color and shape may change, and numbness is possible. An exact fracture cannot be confirmed without an image.

What an elbow joint dislocation is

An elbow dislocation is a displacement of the articular surfaces relative to each other, in which the normal articulation of the bones is disrupted. Dislocation is one of the possible causes of elbow pain along with sprains, fractures, bursitis, and arthritis. It is difficult to distinguish a dislocation from a fracture or sprain by appearance; an image is needed.

How to distinguish an elbow dislocation from a fracture

Understanding what exactly happened — a fracture, a dislocation, or a severe sprain — can be difficult, and an X-ray is usually needed. The following are guides for you — not a diagnosis, but a reason to seek help:

• sharp pain that makes it impossible to use the arm, or pain that intensifies;
• marked swelling or a bruise that is growing;
• a feeling of stiffness, difficulty moving the elbow;
• a change in color, shape of the arm, or an unnatural angle;
• numbness, tingling, or "pins and needles" in the arm.

Any of these signs is a reason to see a doctor, not to wait for it to "go away on its own."

Which signs indicate a severe injury

Immediate help is needed if the injured arm is numb, tingling, there is severe bleeding from a wound, bone is protruding from the skin, or the arm has changed color or shape or is at an unnatural angle. This is no longer about observation at home.

An elbow injury by itself is not a reason to call an ambulance; call 103 or 112 if the arm is numb or tingling, blood is flowing heavily from a wound, bone is visible in the wound, or the arm has changed color or shape or is at an unnatural angle.

How a doctor makes a diagnosis: examination and X-ray

At the appointment, the doctor examines the arm and assesses pain, swelling, deformity, and range of motion. Next is an X-ray: it allows seeing whether there is a fracture and how serious it is. Bone X-ray and elbow X-ray are included in the list of examinations for elbow injuries. A cast is sometimes applied a few days later so that the swelling subsides first.

What complications are possible and when to go urgently to the trauma center

Recovery after a fracture of the arm or wrist usually takes about 6–12 weeks, longer for a severe injury. After the cast is removed, the arm may remain stiff and weak for several months or more. You need to go urgently to a trauma center or see a doctor if the pain intensifies, the cast breaks or becomes too tight or loose, the fingers become numb, swell, turn blue or white, or there is an unpleasant odor or discharge from under the cast. The material is for reference: only a doctor can make an accurate diagnosis and choose the approach after examination and an image.
