A permanent brachial plexus injury can occur during childbirth if shoulder dystocia—a situation where the baby’s shoulder becomes stuck behind the mother’s pelvic bone—is not managed appropriately. In such cases, healthcare providers are trained to use specific, gentle manoeuvres to safely release the shoulder.
If excessive force is applied to the baby’s head or neck, or if proper techniques are delayed or not used, the network of nerves in the neck (the brachial plexus) can be stretched or torn. These nerves control movement and sensation in the arm. Severe damage may not heal, leaving the child with permanent weakness, loss of function, or paralysis in the affected arm.
In a negligence context, the injury may be considered avoidable if it resulted from a failure to follow accepted medical practices for managing shoulder dystocia.
A permanent brachial plexus injury can have wide-ranging effects on a person’s life, particularly because the affected nerves control movement and sensation in the shoulder, arm, and hand.
Physically, the individual may experience weakness or paralysis in the affected arm, limited range of motion, and reduced grip strength. Everyday tasks—such as dressing, writing, eating, or lifting objects—can become difficult or require adaptation. In more severe cases, the arm may not grow or develop normally, leading to visible differences in size or posture.
Functionally, this can impact education and career choices. Certain activities or professions that rely on full upper-body strength or fine motor skills may be challenging or inaccessible. Even routine activities may take longer or require assistive strategies.
There can also be ongoing medical implications. Some individuals require multiple surgeries, physiotherapy, or long-term rehabilitation. Chronic pain or discomfort may persist in some cases.
Psychologically and socially, the effects can be significant. Living with a visible disability or functional limitation may affect self-confidence, especially during childhood and adolescence. Participation in sports or social activities may be limited, which can influence social development and overall quality of life.
Overall, a permanent brachial plexus injury is not just a physical condition—it can shape many aspects of a person’s independence, opportunities, and wellbeing over the course of their life.
