Abstract

Background: Calcaneal fractures are the prevailing fractures among the tarsal bones, accounting for around 60% of such fractures and constituting approximately 2% of all fractures in the human body. Primarily, it arises from the occurrence of high-energy trauma, such as incidents involving falls from elevated positions or accidents involving motor vehicles.
Aim of the work: This study aimed to evaluate the functional and radiological outcomes of tongue-type calcaneal fractures treated by percutaneous screw fixation.
Patients and Methods: Twenty-two surgical procedures of closed or open reduction and percutaneous screw fixation in tongue-type calcaneal fractures in twenty cases were involved in this prospective research design, which took place at Al-Azhar University Hospital at New-Damietta and Elsheikh Zayed Specialized Hospital between January 2020 and August 2023.
Results: According to MFS [Maryland foot score], satisfactory results were obtained in 15 cases with an excellent score [90–100] and another 5 with a good score [75–89]; this yielded 90.9% of the cases with satisfactory results. Two cases [9.1%] obtained fair results [50–74]. None of our patients got a lower score. As regard Böhler’s angle and the crucial angle of Gissane, there were highly significant differences between preoperative and postoperative values, which meant improvement of these angles after fixation.
Conclusion:  Percutaneous screw fixation and closed reduction could be the most suitable treatment plan for tongue-type calcaneal fracture, as long as the reduction technique used allows for satisfactory reduction of the fracture fragments and congruent articular surface and the fixation is stable.
