Anders Paulsen, Marianne Lind, Thomas Colding, Michael Mørk Petersen Orthopaedic Department, Rigshospitalet Background: Previous studies comparing operative and non-operative treat- ment for displaced intraarticular calcaneus fractures (ICF) have reported con- flicting findings. Purpose / Aim of Study: Describe the demography of our patient cohort and quantify the early complication rate and the radiological results after surgical treatment of ICF. Materials and Methods: In 2013-2016 we operated 167 consecutive pa- tients (49 (7-91) years, F/M= 35/132) with 179 calcaneus fractures, 155 were ICF. All fractures were evaluated pre- and post- operatively with plain X-rays and CT. ICF were classified by the Sanders classification (type 2 (n=99), type 3 (n=40), type 4 (n=8)) or were sustentaculum fractures (n=8) and the extraarticular fractures were beak fractures (n=24). The operative technique was selected by the surgeon and was for the ICF osteosynthesis (using a si- nus tarsi (n=90) or L/J shaped lateral approach (n=55)) or primary arthrodesis (n=10). Statistics: Wilcoxon test. Findings / Results: For 126 ICF treated with plate osteosynthesis and com- plete pre- and postoperative X-rays the mean (range) Bohler’s angle (BA) was improved by 17 degrees (p<0.001) from a preoperative BA of mean 11 (-20- 40) to a postoperative BA of mean 28 (11- 41). The mean (range) Gissane’s angle (GA) was improved by 16 degrees (p<0.001) from a preoperative GA of 109 (25-147) to a postoperative GA of 125 (104-147). 137 ICF treated with plate osteosynthesis had a postoperative joint congruence with a perfection reduction (0 mm) in 48 % and acceptable reduction (1-2 mm) in 42 %. 5 ICF were revised within the 2 months postoperatively because of deep infection (n=4, arthrodesis/lateral approach=1/3) or substandart osteosyntesis (n=1, sustentaculum fracture). Conclusions: We found a statistically significant improvement in BA and GA after osteosynthesis of ICF and a low revision rate for deep infection. 188.
