Trigger Finger Syndrome

The trigger finger syndrome is often caused by strenuous activities, but it can also develop in the context of a rheumatic disease. The flexor tendon that belongs to the affected finger thickens like a nodule. This tendon is in front of a ring band that connects the tendon’s sheath (in which the tendon goes through) to the bone. As a result of this thickening, the tendon cannot slide under the ring ligament as expected. This occurs when the person is bending and stretching his finger. Acoustically, this overcoming of the ring ligament is associated with a snapping noise that occurs when stretching or bending the finger.

Via the assistance of a “ring band splitting”, this tendon can glide freely again. In this surgical procedure the ring ligament is split along its longitudinal axis, and usually a local anaesthetic is required for this operation.

Karpal Tunnel Syndrome

A pressure load on the nerve occurs when the median nerve or the metacarpal nerve, which is in the wrist tunnel (carpal tunnel)is pinched.That is how the carpal tunnel syndrome occurs. Carpal tunnel syndrome is most often caused by overloading the wrist but diseases or injuries in the wrist area can also be a possible cause. Initially, complaints such as tingling sensations only occur after

the wrist has been strained. At an advanced state, patients complain of severe pain radiating from the hand to the arm and shoulder.

Conservative treatment is recommended (i.e. edication, physical therapy or wrist splint). Subsequently, carpal tunnel syndrome can be treated surgically.
