Overstretching

A hyperextended thumb is an acute condition. This means that the thumb is bent backward or sideways due to incorrect blocking of a kick or punch, or from another form of impact. The ulnar collateral ligament, or joint ligament, is strained or partially torn as a result. In some cases, it may even be completely torn — in which case surgery is required. An injured thumb is more common because it is positioned differently from the other fingers.

Treatment and recovery of a hyperextended thumb

Movement is beneficial for faster recovery, but it’s important to avoid irritating the sensitive thumb through repeated major or minor hyperextensions. Even small irritations can significantly delay the healing process. Depending on the severity of the hyperextension, you may opt for physiotherapy or hand therapy, immobilization with a splint or cast for 3–4 weeks, or surgical repair. If the hyperextension is mild or if you’ve had surgery, there are also products you can use to prevent or treat it. At Podobrace, we offer various thumb braces that provide support for this condition.
