What is the prevalence of Erb's Palsy?

Erb's Palsy, a form of brachial plexus birth palsy, has an estimated incidence of approximately 0.5 to 2 per 1,000 live births in developed countries. While many infants recover spontaneously, the condition is not considered "rare" in a global sense, though persistent cases requiring long-term intervention are less frequent.

How common is Erb's Palsy?

The incidence of Erb's Palsy varies based on obstetric practices and birth weight distribution. While it is one of the most common peripheral nerve injuries in newborns, exact prevalence data for the total population is difficult to track because most cases resolve within the first year of life. When Erb's Palsy does not resolve, it results in permanent brachial plexus injury, which is significantly less common.

Are there demographic or gender differences in Erb's Palsy?

Research indicates that Erb's Palsy affects males and females at nearly equal rates. The primary risk factors are mechanical rather than genetic or ethnic, including:

• Macrosomia (birth weight greater than 4,000g).


• Shoulder dystocia during labor.


• Prolonged second stage of labor.


• Assisted vaginal delivery (forceps or vacuum extraction).

What challenges exist in tracking Erb's Palsy statistics?

Tracking the true prevalence of Erb's Palsy is complicated by inconsistent diagnostic reporting. Mild cases that resolve quickly are often not documented in long-term medical registries, leading to a disparity between initial birth injury counts and chronic case counts. At DiseaseMaps.org, we have 1 community member sharing their journey with Erb's Palsy, providing a vital, real-world perspective on the long-term management of this condition that clinical statistics often overlook.

Next steps

• Consult a pediatric neurologist or an orthopedic surgeon specializing in brachial plexus injuries for an accurate assessment.


• Engage in early physical or occupational therapy, which is the cornerstone of treatment for Erb's Palsy.
