Although<unk>  remains asymptomatic, a number of case reports suggested that symptoms could develop after a forceful extension of the index finger with the thumb in a flexed position. Symptoms also develop from heavy and repetitive use of the wrist and forearm and can also develop in those who require fine and independent functionality of the fingers, such as musicians. This abnormality is clinically evident when the patient is unable to flex the thumb without flexing the distal interphalangeal joint of the index or middle finger or vice versa. Flexor tenosynovitis is a common finding in the patients with<unk><unk><unk>  syndrome. Another hypothesis is that anatomical<unk> s, which in this case is an additional tendon slip, may act as space-occupying lesions and potentially contribute to carpal tunnel syndrome.
