FIELD: medicine.
SUBSTANCE: method involves accessing articulation from dorsal hand surface, dissecting finger extensor mechanism and excising articulation. The finger extensor mechanism is longitudinally dissected with extensor edges brought apart. Bone commissures are cut between articulation ends of metacarpophalangeal articulation, and the metacarpophalangeal articulation is bent to an angle of 90°. Marginal excision is carried out on metacarpal bone head only, retaining articulation surface of the basic finger phalanx and soft capsule ligament tissues making bridge between inferior hemisphere of metacarpal bone head and the like hemisphere of basic finger phalanx base. Then, articulation fissure is widened in doing passive movement with movement volume in the metacarpophalangeal articulation being within the limits of 180-90°. The mobilized articulation having been bent to an angle of 90°, it is fixed with wire and sutures are placed on the extensor.
EFFECT: repaired ankylosed articulation function; reduced traumatic complications due to surgical intervention.
