Sustentaculum tali screw fixation for the treatment of Sanders type II and III calcaneal fractures / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To explore the clinical outcomes of open reduction and internal fixation with calcaneal locking plates in treating Sanders type II and III calcaneal fractures.</p><p><b>METHODS</b>From January 2010 and October 2012, 38 calcaneal fractures with Sanders type II or III were treated with open reduction and internal fixation with calcaneal locking plate. According to the Sanders classification, 15 fractures were classified as type II, 23 fractures as type III. The patients were divided into two groups (group A and B) according to the different fixed methods. Sustentaculum tali was fixed with one screw in group A, including 13 males and 5 females, with a mean age of (38.56±8.03) years old (ranged, 25 to 55). And sustentaculum tali was not fixed in group B, including 16 males and 4 females, with a mean age of (42.35±8.29) years old (ranged, 29 to 53). Clinical effects were evaluated according to the changes of Böhler's angle and the Maryland Foot Score and VAS score.</p><p><b>RESULTS</b>All patients were followed up from 12 to 20 months with a mean of 14 months. Böhler's angles and subtalar joints obtained satisfactory reconstruction in all patients. One year after operation, the mean Maryland Foot Score was 88.61±7.59 in group A; and was 82.40±9.24 in group B; Maryland Foot Score of group A was higher and foot functional rehabilitation was better than group B. The mean VAS score was 13.39±11.47 in group A; and was 22.50±13.10 in group B; VAS score of group A was lower and foot pain was less than group B.</p><p><b>CONCLUSION</b>Sustentaculum tall screw fixation has advantages of strong fixed strength, high stability, less postoperative pain, rapid functional recovery in treating Sanders type II and III calcaneal fractures.</p>
