De Quervain’s disease
It is a hand condition that causes painful swelling of the tendons present in the waist that supports the movement of thumb away from the hand. It involves pain on the radial size of the waist and results in thickening of the ligamentous structure that covers tendons in the first dorsal area of the waist. As both trigger finger and De Quervain’s disease are associated with the inflammation of the tendons of hand; therefore, the patient suffering from de Quervain’s disease can also develop trigger finger. Due to de Quervain’s disease, trigger finger can occur on the area of the thumb due to swelling of tendons in the first dorsal compartment of the waist.
