Operative correction of posttraumatic and congenital swanneck deformity--a new technique.

Volar plate reconstruction by using a part of the slip of the superficialis tendon is a new technique in the treatment of posttraumatic and congenital swanneck deformity. This small series represents two patients with a posttraumatic swanneck deformity due to volar plate rupture and one patient with a congenital swanneck deformity in six fingers. The results of the operation with a two years follow-up show seven fingers with a normal flexion-extension range without hyperextension. Only one finger has an extension lag of five degrees. All fingers have a normal grip strength and normal fine movements without pain. There were no complications.
