Carpal tunnel release operation means that the nerves passing to your fingers mainly the median nerve was irritated or obstructed during its passage to your fingers through the flexor retinaculum at the level of the wrist. The flexor retinaculum is a kind of sheath that surrounds some nerves and structures passing through your wrist region, so this sheath is cut to free your median nerve.  Flexor synovectomy means removal or excision of a peace of the synovial which is a thin layer surrounding your wrist joint that allows flexion. maybe it had a minor fissure or fracture that need to be removed to immobilize your wrist joint.  Hope you feel better after your operation and follow your surgeon instructions, and you may need physiotherapy sessions with a chiropractor to manage your injured joint to fully recover.
