Abstract:
Objective To compare the effects of fixations with dynamic hip screw (DHS),percutaneous compression plate (PCCP) and proximal femoral nail anti-rotation (PFNA) for treatment of intertrochanteric femoral fractures with paries medialis defect.Methods We reviewed the 82 patients with femoral intertrochanteric fracture and paries medialis defect who had been treated at our department from January 2011 to July 2016.They were 42 men and 40 women,aged from 27 to 91 years (average,73.0 years).According to the AO classification,72 cases belonged to type 31-A2.2,10 to type 31-A2.3.Of them,9 cases were treated with DHS,17 cases with PCCP and 56 cases with PFNA-1].The 3 groups were compared in terms of intraoperative blood loss,blood infusion,fluid infusion,operation duration,time for fracture union,postoperative complications and Functional Recovery Score (FRS) of the hip 12 months after operation.Results The fluid infusion [1,100 (850,1,100) mL] and intraoperative blood loss [60 (5,100) mL] in the PCCP group were significantly less than in the PFNA group [1,100 (1,000,1,700) mL and 150 (50,300) mL] and the operation duration (91.4 ± 29.2 min) in the former was significantly shorter than in the latter [121 (85,185) min] (P ＜ 0.05).No significant difference was found between the 3 groups in blood infusion (P ＞ 0.05).Of the patients,57 (8 DHS,12 PCCP and 37 PFNA ones) were followed up for an average of 47 months (from 15 to 85 months).There were no statistically significant differences between the 3 groups in time for fracture union,complications,or average FRS score of the hip 12 months after operation (P ＞ 0.05).Conclusions For unstable intertrochanteric fractures with paries medialis defect,it is not clear that intramedullary nails are superior to extramedullary fixation.Intramedullary nails like PFNA may be suggested for patients with better preoperative conditions while extramedullary fixation like PCCP suggested for those with poor general conditions.
