200 · DOS Abstracts Demography and Complications of Surgical Treated Talar Fractures Camilla Hattig Bonefeld, Anders Paulsen, Michael Mørk Petersen, Marianne Lind Orthopedic Department, Rigshospitalet Background: More than 60-65% of the surface area of the talus bone is cov- ered with articular cartilage, which limits the intra-osseous blood supply. Talus account for 0.5 % of all fractures, and only 3% of all foot fractures. The primary mechanism of injury is often severe, and includes high energy, often making the patient group multi-traumatic. Associated skeletal lower leg injuries has been reported in 54% of all talus fractures, and 8% were multi-traumatic with injuries at other locations of the body. Sequelae such as avascular osteonecrosis (54%) and post-traumatic arthritis (25%) are common complications seen after treat- ment of all types of talus fractures. Purpose / Aim of Study: Describe the demography and early complication rate after surgical treatment of both talar neck and corpus fractures. Materials and Methods: In 2010-2013 we operated 29 consecutive patients (34 (14-54) years, F/M= 11/18) with 33 talus fractures, 19 corpus fractures and 14 neck fractures. All fractures were evaluated pre- and post- operatively with plain X-rays and CT. The operative technique was selected by the sur- geon and was either ORIF (n=29), external fixation (n=3) or primary arthrodesis (n=1). Findings / Results: Corpus fractures were classified by the Sneppen classifica- tion (type 1 (n=3), type 2 (n=3), type 3 (n=3) type 5 (n=10)) and neck frac- tures by the Hawkins classification (type 1 (n=7), type 2 (n=3), type 3 (n=3) type 4 (n=1). 19 patients sustained their injury in a high-energy trauma, 7 pa- tients had an open fracture, and 4 patients had bilateral fractures. The number of associated injuries found were: 1-2 (n=15), 3-4 (n=5), 5 or more (n=2). 11 patients required more than one surgery in order to gain soft tissue coverage, infection control and ultimate heling. 2 patients had secondary arthrodesis of the ankle joint caused by AVN. Conclusions: We found a higher number of associated injuries in patients with talus fractures than seen in other studies. The number of AVN was lower than otherwise reported, however, we experienced a high number of surgical inter- ventions in order to archive healing. 179.
