Extensor tendons of finger anomalies (disorder)
	Extensor tendons of finger anomalies
	Hapnes Boman Skeie syndrome
	A rare genetic congenital limb malformation with characteristics of bilateral anomalous attachment of the extensor tendons of the four ulnar fingers. Attachment occurs to the medial and lateral aspects of the middle phalanges leading to constant flexion in the mid phalangeal joints and inability to extend the fingers. There have been no further descriptions in the literature since 1980.
