Background: Proximal tibial epiphysis fractures are challenged for total approach. Management remains debated.
Purposes: evaluate the results of surgical treatment.
Methods: Retrospective study of 29 cases of proximal tibial epiphysis fracture/tibial tubercle avulsion managed by closed or open reduction and fixation with pinning, screw and plate from January 2016 to December 2017. The fractures were classified according to Salter and San Diego. The functional evaluation was at the final follow-up of a minimum of 18 months.
Results: Tibial tubercle fracture (72%) was more frequent than proximal tibial epiphysis fracture (28%); age of TTA was older than PTEF (p<0.05); dominant injury mechanism was indirect for TTA (76%), but direct for PTEF (75%). TTA was mostly fixed by screws (95.2%), whereas PTEF was never fixed by unique screws. The length of stay for PTEF was longer than for TTA (p<0.05). Average follow-up was 30.5 months (21-41 months); good functional recovery was for both types of fracture.
Conclusion: Injury mechanism was indirectly dominant for TTA, and directly for PTEF with risk of compartment syndrome and vascular injury. However, good functional recovery was both types of fracture at final follow-up.
