Abstract

PURPOSE: The purpose of this study was to investigate the efficacy of bone graft use in the treatment of displaced intra-articular calcaneal fractures.
MATERIALS AND METHODS
We analysed retrospectively 40 displaced intra-articular calcaneal fractures, which had undergone open reduction and internal fixation without bone graft from June 1989 to July 1998. Radiological assessments were made from the lateral view of the affected calcaneus, recording the Bohler angle, the Gissane angle and ratio of height/width of the calcaneus. Matching criteria included Essex-Lopresti classification, method of fixation, age, and sex. RESULT: The mean preoperative Bohler angle was -7 degrees(standard deviation [S D ] 1 8 degrees), postoperative Bohler angle was 21 degrees(SD 7 degrees), last follow-up Bohler angle was 1 9 degrees(SD 7 degrees). Bohler angle increased a mean 28 degrees(maximum 70 degrees, minimum 2 degrees). The preoperative Gissane angle was 104 degrees(SD 17.87 degrees), postoperative Gissane angle was 1 0 6 . 2 degrees(SD 10.07 degrees), last follow-up Gissane angle was 104.48 degrees(SD 10.1 degrees). The preoperative ratio of height/width of the calcaneus was 0.568(SD 0.076), postoperative ratio was 0.637(SD 0.037), last follow-up ratio was 0.648(SD 0.038). There was no significant differences in fracture pattern, method of fixation, age, and sex(P>0.05).
CONCLUSION
The result of this study showed that there was no significant change in serial radiologic evaluation. Bone graft was not served to the effectiveness or security in the treatment of displaced intra-articular calcaneal fractures.
