Poster Topic: Trauma - Ankle / Foot Abstract number: 25864 A CADAVERIC STUDY COMPARING TWO-HOLE LOCKING PLATE TO QUADRICORTICAL SCREW FIXATION IN MAISONNEUVE FRACTURE Taher YOUSRI 1 , Gardner RICHARD 1 , Clark DAMIAN 1 , Holmes FIONA 2 , Phillip POLLINITINE 2 , Tim HOLSGROVE 2 , Miles TONY 2 , Jackson MARK 1 1 University Hospitals Bristol NHS Trust, Bristol (UNITED KINGDOM), 2 University of Bath, Bath (UNITED KINGDOM) Introduction: Treatment of syndesmotic injuries is a subject of ongoing controversy. Locking plates are fixed angle device that have been shown to provide both angular and axial stability by eliminating the risk of the screw toggling in the plate. The aim of this study is to determine whether a two-hole locking plate has biomechanical advantages over conventional screw stabilisation of the syndesmosis in this pattern of injury. Methods: We have used 6 pairs of fresh-frozen human cadaver lower legs. The syndesmotic ligaments, interosseous membrane and the deltoid ligament were sectioned to simulate an unstable Maisonneuve fracture. The limbs were then mounted on a servo-hydraulic testing rig and axially loaded with 800N for 14000 cycles. Each limb was compared with its pair; one receiving stabilisation of the syndesmosis with two 4.5mm quadricortical cortical screw, the other a two-hole - 3.5mm locking plate with locking screws (Smith and Nephew). Failure was defined as fracture of bone or metalwork, syndesmotic widening or axial migration>2mm. Results: All ankles showed failure of the metal work with fracture of the lateral malleolus at the level of the syndesmosis following axial loading and the application of an external rotation force at an average of 14000 cycles. In 4 of the 6 pairs, using a locking plate, the torque required to produce failure was at least double the force required when using syndesmotic screws. Conclusion: Locking plate are more stable constructs in resisting shear stress, as well as controlling tensile forces across the syndesmosis. 511

Therapeutic rules are relatively clear in closed trauma of the ankle, while skin injury<br />
makes sometimes difficult the choice between different techniques, concerning the<br />
incision and the type of bone stabilization, definitely influenced by the time from<br />
trauma and by the injury of the skin. The authors analize 20 patients with open ankle<br />
trauma, operated between 01.01.2005-01.01.2008, age 24-52 yrs. The injuries were<br />
both bony and capsular-ligamentous in 13 cases, while 3 patients had open<br />
dislocations without fractures. Following Gustillo-Andersen classification, the injuries<br />
were type I-2 cases (12.5%), type II-6 cases (37.5%), type III-8 cases (50%).<br />
Different therapeutical problems were raised for each type of open injury requiring<br />
different surgical techniques, follow-up was performed until 24 months. Postoperative<br />
outcome was evaluated from the point of view of: functional recovery,<br />
social and professional re-integration, the incidence of the complications. The<br />
circumstances influencing post-operative outcome were: the time between trauma<br />
and surgery, the type of the skin and soft tissue injuries. Septic complications<br />
appeared in 12.5% cases (2 patients) with Staphylococcus aureus, without the need<br />
of implant removal. Because one of the 3 cases with type III C injury arrived at our<br />
hospital 36 hrs after trauma with irreversible ischemia, amputation was indicated. The<br />
treatment of open trauma of the ankle is difficult since the cutaneous injury narrows<br />
the therapeutical options and post-operative complications are more frequent. The<br />
key of success in these cases is represented by early surgery adapted to the soft<br />
tissue injury.<br />
