Your toddler suddenly won't lift their arm. They're crying, holding it down at their side, and won't let you touch the elbow. This is nursemaid's elbow — a partially dislocated elbow that happens in seconds and is fixed in seconds. No surgery. No sedation. No cast. Most children are using the arm again within 5 to 15 minutes of the reduction.
X-rays are normal in nursemaid's elbow — this is a ligament injury, not a fracture. X-rays are only needed if the history or exam raises concern for something else.
What Happened
Nursemaid's elbow is a subluxation — a partial dislocation — of the radial head at the elbow. It is the most common elbow injury in young children, occurring most often between the ages of 1 and 5. The annular ligament, a ring of tissue that holds the radial head in position at the elbow joint, slips over the radial head and becomes trapped in the joint when the arm is suddenly pulled.
The mechanism is almost always the same: a sudden longitudinal traction force on an extended, pronated arm. The classic scenario is a caregiver pulling a child up by the hand to avoid a fall, swinging a child by the hands during play, or a child being pulled quickly by the hand while walking. In a young child's elbow, the radial head is not yet fully developed and the annular ligament is relatively loose — both factors that make the injury easy to sustain.
The result is immediate: the child cries briefly, then holds the arm down at the side, slightly bent at the elbow and pronated (turned inward at the wrist). They refuse to move it, use it, or allow it to be touched near the elbow. They are not in constant agony — they just won't use the arm. Parents are often alarmed because the child seemed fine one moment and suddenly won't lift the arm at all.
The good news is that this injury is easily and quickly corrected. A reduction maneuver performed by Dr. Graham takes only a few seconds. Most children resume normal use of the arm within 5 to 15 minutes — sometimes immediately. No sedation, no cast, no surgery required.
The annular ligament (green) encircles the radial head at the elbow. In young children, the radial head is smaller relative to the ligament — when a sudden pull is applied to the arm, the annular ligament can slip over the radial head and become trapped in the joint. This is the subluxation of nursemaid's elbow.
As the child grows, the radial head enlarges and the annular ligament tightens around it — making this injury progressively less likely. By age 5 to 6, nursemaid's elbow becomes rare.
Is This Nursemaid's Elbow?
Nursemaid's elbow has a characteristic presentation that experienced parents and clinicians recognize immediately. Knowing what to look for helps you act quickly and confidently.
Treatment
Dr. Graham performs a closed reduction maneuver in the clinic. Hyperpronation is tried first — it is faster, less painful, and has a higher first-attempt success rate. Supination-flexion is used if hyperpronation does not reduce the joint.
The hyperpronation technique is Dr. Graham's preferred first attempt. It is faster, causes less discomfort than supination-flexion, and has a higher single-attempt success rate in most studies.
If hyperpronation does not produce a click and restore arm use, supination-flexion is performed. This is the traditional technique and is effective in cases where the annular ligament has not reduced with pronation alone.
After Reduction
For a first-time nursemaid's elbow in a child without prior episodes, no immobilization is needed after successful reduction. The child can use the arm normally once it has been reduced. No sling, no splint, no restrictions. The annular ligament is back in place and the elbow is stable.
Recurrence changes the management conversation. Children who have had two or more episodes of nursemaid's elbow have a lax annular ligament that is prone to re-subluxing with relatively minor traction. After reduction of a recurrent episode, Dr. Graham may recommend a brief period of protection — typically a sling for a few days — to allow the ligament to settle, along with more specific guidance on activity modification and handling.
The most important message after any episode of nursemaid's elbow — first or recurrent — is prevention. The annular ligament is already demonstrated to be susceptible. Until the child is 5 to 6 years old and the radial head has grown enough to anchor the ligament reliably, the injury can recur from the same mechanisms. Prevention guidance is the most valuable thing a parent can take home from this visit.
Nursemaid's elbow is almost always preventable. The annular ligament slips under one specific type of force — sudden longitudinal traction on the arm. Eliminating that force eliminates the injury. These habits take about two days to become automatic.
Most nursemaid's elbow cases are diagnosed clinically — a classic history and characteristic arm position in the right age group is enough to attempt reduction without X-ray. But several scenarios warrant imaging before or after a reduction attempt.
If there is any doubt, X-rays are fast, simple, and definitively rule out a fracture. Dr. Graham will image when the clinical picture is not clearly consistent with isolated nursemaid's elbow.
"My two-year-old suddenly wouldn't use her arm and was crying. I was terrified it was broken. We went to JOI Now, Dr. Graham fixed it in about 30 seconds, and she was reaching for her toy before we even left the room. He also showed us exactly how to prevent it from happening again. Best experience we've had with any doctor."
