Abstract

Objective: In the past, treatment of intertrochanteric fractures was mainly to open reduction and internal fixation with DHS, locking plate … require extensive exposure, open fractures, will lead to blood loss, pain, and limited mobility postoperatively and lead to complications.In cases of unstable fractures with large external wall injuries treatment with DHS, locking plate often lead to secondary displacement and failure of treatment. With the introduction of intramedullary nails Gamma, PFNA, Reconstruction, and the latest generation of nails InterTAN, with minimally invasive surgical technique, without opening the fracture, shorter surgery time and blood loss, mechanically more stable, helping patients to move and weight bearing early after surgery and prevent complications due to prolonged lying down. This report aims to evaluate the results of treatmentintertrochanteric fractures with closed reduction technique on the orthopedic table and internal fixation with the proximal femoral nail.
Material and method: We perform closed reduction on the orthopedic table using C Arm. And using surgical techniques applied according to AO on 58 cases of intertrochanteric fracture. Record the length of incision, surgery time, estimated blood loss, VAS pain score, hospital stay, complications, treatment results, hip function according to Harris scale. at 3 months, 6 months and 12 months.
Results: The mean age was 78.86 ± 11.67 (38 - 97), female accounted for 72.4%. Means of nailing PFNA 41 cases, Gamma nails 5 cases, Reconstruction nails 12 cases. Average operative time 70.34 ± 20.5 minutes (45 - 135), incision size 6.70 ± 1.09 cm (5 - 10), estimated average blood loss 257.1 ± 163, 04 mL. The mean preoperative and postoperative VAS pain scores were 7.26 and 2.79, respectively. Average length of hospital stay was 13.37 ± 4.38 (5 - 24). Intraoperative complications recorded 1 case of femoral shaft fracture and 1 case of failure of closed manipulation. X-ray of bone healing was recorded in all patients at follow - up examination, 4 cases with fracture deformity. Harris score at 3,6,12 months is 76.42 ± 13.01, 85.96 ± 6.36, 90.25 ± 2.63, respectively.
Conclusions: Treatment with a proximal femoral nail (PFN) showed that minimally invasive surgical technique, reduced blood loss, small incision size, allows early full weight bearing and postoperative recovery
