Authors evaluate their own experience in the treatment of constricting annular grooves of limbs, especially the hand, which in the total number of treated congenital anomalies of limbs account for 172 cases (17 %). Hands were affected in 152 cases (88,4 %), legs in 20 cases (11,6 %). The authors point out a great variety of the affection by Constricting annular grooves and ensuing from it a strictly individual rational surgical technique. As the most important they consider adequate followup and repeated assessment of the condition of the malformed limb until adult age. They state that even with amputation of part of fingers the patients are able to compensate sufficiently for their loss by the unaffected part of the hand. Therefore it is necessary to accept their negative standpoint as concerns another suggested surgical treatment. Key words: hand, congenital anomalies, constricting annular grooves of the hand.
