OBJECTIVE: The aim of this study was to compare clinical and radiological outcomes of screw fixation alone versus screw with small locking plate fixation techniques in the management of intra-articular calcaneal fractures by minimal invasive surgery.
METHODS: A total of 42 patients treated with minimally invasive surgery because of an intra-articular calcaneal fracture were retrospectively reviewed and included in the study. The patient were then divided into two groups based on the implemented surgical technique: Group A, 20 patients (16 male, 4 female; mean age = 43.41 ± 15.50) receiving screw fixation alone and group B, 22 patients (17 male, 5 female; mean age = 43.38 ± 14.00) receiving screw with small locking plate fixation. The radiographic assessment included Bohler's, Gissane, joint line parallel, and calcaneal varus angles at immediate post-operative and 2-year follow up period through the calcaneal axial and lateral foot radiographs.
RESULTS: There was a significant increase in joint line parallel angle from post-operative period to 2-year follow up in Group A compared to Group B, mean (SD) 3.27 (2.15) degrees versus (vs) 0.44 (3.00) degrees, P = 0.025. No statistical significant difference of the immediate, 2-year post-operative period and the change in Bohler's-Gissane angle, calcaneal varus, and FAAM of ADL between groups were observed, P > 0.05. For time-point comparisons in each group, there was a significant loss of calcaneal varus and increase in joint line parallel angle from post-operative period to 2-year follow up in Group A, from mean (SD) 1.82 (11.22) to 4.41 (9.73) degrees and 4.09 (5.32) to 7.36 (5.24) degrees, P = 0.047 and <0.0001, respectively. Group A had statistical significant less complications as zero vs 5, P = 0.049.
CONCLUSION: The screw fixation alone seems to provide inferior stability of posterior facet fixation and calcaneal varus reduction with lower complication rates compared to screw with small-locking plate fixation.
LEVEL OF EVIDENCE: Level III, Therapeutic Study.
