ObjectiveTo compare the clinical efficacy of dynamic hip screw (DHS) versus proximal femoral nail antirotation (PFNA) in the treatment of Tronzo-Evans typeⅠ and type Ⅱ femoral intertrochanteric fractures. MethodsSixty femoral intertrochanteric fractures patients in Tronzo-Evans typeⅠand typeⅡ were selected, of which 28 cases received DHS internal fixation as DHS group, whereas 32 cases, whose general data were comparable to the DHS group, received PFNA internal fixation during the same period as PFNA group. The therapeutic effect and hospitalization costs were compared between the two groups. ResultsThe operation time, intraoperative blood loss, and postoperative drainage volume of the PFNA group were less than those of the DSH group (all P＜0.05). There were no significant differences in fracture healing time, Harris scores 3, 6, and 12 months after operation (all P＞0.05). There was no significant difference in the incidence of complications between the two groups (10.71% vs. 9.38%, P＞0.05). The total treatment costs of the PFNA group were (17,000±500) yuan, which were higher than those of the DHS group with (11,000±800) yuan (P＜0.05). ConclusionFor femoral intertrochanteric fractures in Tronzo-Evans typeⅠand type Ⅱ, if the patient has poor surgical tolerance, considering the operation time, intraoperative blood loss, and postoperative drainage and other issues, PFNA is recommended. If the patient has a good physical condition, because of the same long-term effects of the two methods and the relatively low medical costs of DHS, it can be a good choice for primary hospitals and patients with economic difficulties.
