Method of osteosynthesis of closed fractures of the II-V metacarpal bones with wires

摘要

The invention relates to medicine, namely to traumatology and orthopedics and is intended for osteosynthesis of closed fractures of the II-V metacarpal bones of the hand.The method, according to the invention, consists in that in the region of the damaged metacarpal bone base, on the back of the hand, it is performed the skin incision of a length of 0.2...0.4 cm, there are moved apart the soft tissues to the bone and through the wound is introduced a wire at an angle of 30...45° with respect to the axis of the forearm, perforating the first cortical layer, introducing it up to the cortical layer of the palmar part and sliding the wire thereon, it is introduced up to the focus of fracture, there are repositioned the fragments, and then the wire is introduced further into the distal fragment up to the cortical layer of the bone head. It is performed the second incision on the dorsal side of the bone of a length of 0.2...0.4 cm, at the level of the damaged metacarpal bone head, there are moved apart the soft tissues to the bone and through the wound is introduced another wire, perforating the first cortical layer, introducing it up to the cortical layer of the palmar part and sliding the wire thereon, the wire is introduced through the focus of fracture into the proximal fragment. It is carried out the control radiogram and if it is ascertained an optimal adaptation of the fragments then the ends of the wires are cut at the skin level. If it is revealed the diastasis between the fragments, then the wires are bent and compressed toward each other and fixed. It is applied an aseptic dressing in the region of skin incisions, then a plaster splint on the palmar surface, from the level of the distal palmar fold up to the level of the distal third of the forearm.
