[Lumbrical plus syndrome].
A rare case of paradoxical extension of the medius finger - the so-called lumbrical plus finger syndrome-is described. At operation was found a fibrous adherence of the third lumbrical at the sheath of the flexor digitorum profundus. Some of pathological mechanisms are discussed. A satisfactory result was obtained after the resection of the tendon of the second lumbrical.
