Fratura pantrocantérica: incidência da complicação em pacientes com fratura trocantérica tratados com parafuso dinâmico de quadril em um hospital do Sul do Brasil

Abstract

ObjectiveThe aim of this study was to investigate the incidence of pantrochanteric fractures in the cases of trochanteric fractures treated with dynamic hip screw in this hospital. MethodsA sample of 54 patients with trochanteric fractures treated with dynamic hip screw was included in this retrospective study. Preoperative radiographs were evaluated for fracture classification using the AO/OTA system, identification of radiographic osteoporosis, and measurement of the lateral femoral wall thickness, whereas in the immediate postoperative images the presence of pantrochanteric fracture was evaluated. ResultsThe final sample presented the incidence of 16.7% of pantrochanteric fractures. The thickness of the lateral wall was significantly lower in the group with the complication (p < 0.001). Although fractures classified as 31.A2 were more numerous in the group with pantrochanteric fracture, the difference was not statistically significant (p = 0.456). ConclusionThe percentage of pantrochanteric fractures in this service is in accordance with previous studies. There was an association between lateral femoral wall thickness and the occurrence of iatrogenic fracture of the lateral cortex. There was no significant difference between fracture classification and pantrochanteric fracture, possibly due to sample size.
