Evaluation of the result of articular facet reduction and intraoperative distraction for sanders type iv calcaneal fracture n polytraumatized patients.

OBJECTIVE

Aim: The aim of this study is to evaluate the results of combined repositioning - open repositioning of the depressed articular facet combined with intraoperative two-vector distraction of the calcaneus with a new external fixation distraction apparatus and osteosynthesis with a calcaneal plate with angular stability of a Sanders IV type fracture..

PATIENTS AND

METHODS

Materials and

Methods

This study evaluates the results of sequential two-vector distraction with a repositioning apparatus for open reduction and internal fixation (ORIF) of a Sanders IV calcaneal fracture. The method was applied in the treatment of 25 patients with polytrauma with 30 Sanders IV calcaneal fractures treated in Astana multiprofile hospital No. 1 and National Scientific Centre of Traumatology. 1 and National Scientific Centre of Traumatology and Orthopaedics named after academician N.D. Batpenov (Republic of Kazakhstan) from 2018 to 2022.

RESULTS

Results

At final examination, the values of Bohler angle, Gissane, posterior articular facet tilt, width, height, and length of the calcaneus were significantly higher (p<0.001) preoperative values and were identical to postoperative values.

CONCLUSION

Conclusions

The mean VAS pain score was 2.14 (standard deviation 1.08 and range 1.5-5.5). The mean clinical outcome score on the AOFAS was 92.8 points (SD 5.7, range 74-97). Two-vector distraction of the calcaneus with external fixation apparatus in ORIF of Sanders IV type intra-articular fracture is an effective method of repositioning a three-dimensional deformity of the calcaneus.
