AbstractThe distal radius is one of the commonest sites of fracture, and this injury is sometimes associated with fracture of the distal ulna. In recent years, surgical treatment of distal radius fractures has consisted increasingly in internal fixation with locking plates followed by early functional postoperative treatment. The associated injury to the distal ulna has so far not received much attention in the literature. Various techniques have veen described for its treatment: Kirscher wire fixation, tension band wiring, and internal fixation with screws and plates. Following positive results with elastic stable intramedullary nailing (ESIN) in the treatment of shaft fractures in children this technique was also applied in in fractures in adults (forearm, clavicle). Use of this technique for stabilisation of distal ulnar fractures has not previously been reported. In the course of a prospective longitudinal study (EBM level II), in 26 patients with an average age of 73.6 (42-88 years), bone healing in anatomical position was achieved in all cases within 6-12 weeks after closed reduction and anterograde ESIN with subsequent treatment that did not involve immobilization. No length differences of more than 2 mm and no functionally relevant deviations of the ulnar axis were observed. Apart from 3 cases of nail perforation at the distal end of the ulna, which had no clinical manifestations, there were no complications. ESIN offers a minimally invasive option for the treatment of unstable fractures of the distal ulna associated with distal radius fractures; it allows functional aftertreatment and can be regarded at least as an alternative to open reduction with internal fixation.
