Symptoms
- Pain on the thumb side of the wrist, sometimes spreading up the forearm
- Pain when gripping, wringing, opening jars or lifting a baby
- Swelling or a small lump in the area
- A catching or rubbing sensation when moving the thumb
Diagnosis and treatment
Examination and ultrasound in the consulting room confirm the diagnosis, show the thickened sheath and reveal whether a septum divides the compartment, which matters for an effective injection.
Treatment starts with relative rest, a thumb splint and changing the movements that trigger it. If pain persists, an ultrasound-guided injection into the sheath usually brings quick relief. Surgical release is considered in resistant cases.
Frequently asked questions
Why is it so common after childbirth?
Hormonal changes coincide with repeated wrist movements when lifting and holding the baby, which overload these tendons.
Why do the injection under ultrasound?
It allows the medication to be placed inside the sheath, even when it is divided into two compartments, while avoiding the nerve and vein in the area.
