An intraoperative small distractor for non-open reduction and intramedullary fixation of pediatric displaced diaphyseal forearm fractures.

This report describes technical tools for the treatment of pediatric displaced and unstable diaphyseal forearm fractures, which are difficult to treat by manual closed reduction. During intramedullary fixation with Kirchner wires, we propose our original small distractor as an intraoperative distraction apparatus without open reduction. This apparatus is made using parts of the Ilizarov external fixator. Apart from general external fixation devices, our apparatus is adequate for the effective shortening and lateral dislocation of the fracture site. This adequacy is not only because of the three-dimensional control by ball joints but also owing to the gradual adjustment structure of the Quick adjust strut (Orthofix, Verona, Italy), which allows tight and fine stretching, thus making the distractor an effective reduction tool. Our findings show the feasibility and usefulness of our reduction technique and small distractor. Our small distractor is a useful intraoperative distraction apparatus without open reduction for pediatric displaced and unstable diaphyseal forearm fractures that cannot be treated by manual closed reduction. In this report, we describe the distractor, the closed reduction technique, and the clinical results of four representative cases.
