Abstract

Objectives: Evaluating the initial outcome of closed cephalomedullary nail surgery in treatment of intertrochanteric femur fracture in Bach Mai hospital. Methods: We conducted a retrospective cross sectional descriptive study, evaluating the outcome of closed cephalomedullary nail surgery in 39 patients diagnosed with intertrochanteric femur fracture in the period of 2 years, from 1/2021 to 4/2023 at Bach Mai Orthopaedic and Spine Department. Results: The mean age was 67,6 ± 19,1 years. Average operative time 100,8 ± 10,4 minutes. The difference in operation time between 2 groups, short cephamedullary nail group (n₁ = 17) and long cephamedullary nail group (n₂ = 22) were 95 ± 4,7 and 105,2 ± 11,5 minutes, respectively (p = 0,01). Average blood loss was 181,4 ± 142,7 ml, discrimination of blood loss between 2 groups was statistically (98,8 ± 23,3 ml and 245,2 ± 163,3 ml) (p = 0,001). Average length of stay in hospital was 14,3 ± 6,7 days, the figure for short nails group was 9,0 ± 4,4 days, long nails group was 10,6 ± 6,1 days (p> 0,05). Intraoperative complications confirmed in 2 cases (5,1%), 1 case of femoral shaft fracture and 1 case of failure of closed reduction. Harris score at 03 and 06-month follow-up were 79,7 ± 13,5 and 85,5 ± 13,3 (p< 0,05), patients classified to good and very good postoperative functional  group accounted for 70,8%. Conclusion: Closed cephalomedullary nails reduction is minimally invasive osteosynthesis technique in treatment of intertrochanteric femur fracture showed good outcome and short–term follow up.
