title: [Intersesamoid resection-suture of the metacarpophalangeal joint of the thumb. Sesamoidorrhaphy of the metacarpophalangeal joint of the thumb].
abstract: In some cases, congenital or acquired posterior instabilities of the MP joint of the thumb may cause pain or create functional disorders. It is possible to stabilize the metacarpophalangeal joint by partial resection of the ligament joining the two sesamoids which makes it possible to move and suture them toward each other. An enlargement plasty of the pulley then is required. This technique prevents hyperextension but without restricting flexion or opposition. The digital nerves must be carefully identified and protected.
