Minimally invasive percutaneous fixation with cannulated compression screw for young patients with femoral neck fracture / 中国组织工程研究

ABSTRACT

BACKGROUND: Screw fixation is mainly used in the treatment of femoral neck fractures in the youth; therefore, how to reduce surgical trauma, retain sufficient blood supply and reduce postoperative complications becomes so important. OBJECTIVE: To study the efficacy of minimal invasive percutaneous fixation with cannulated compression screws for young patients with femoral neck fracture and its impact on the length of bilateral lower limbs and hip joint function. METHODS: Thirty patients with femoral neck fracture admitted in the Shanghai Pudong Hospital Affiliated to Fudan University from January 2009 to December 2012, were selected as experimental group, followed by subjected to minimal invasive percutaneous traction bed-assisted closed reduction with cannulated compression screws. Meanwhile, 28 cases of femoral neck fracture admitted from January 2006 to December 2009, were given open reduction with square muscle grafting and cannulated screw fixation (control group). The efficacy, intraoperative blood loss, operation time, hospital stay, fracture healing time and incidence of complications were observed. Additionally, the length of bilateral lower limbs and Harris hip scores at 3 months and 1 year postoperatively were compared between two groups. RESULTS AND CONCLUSION: (1) All patients were followed up for 24-60 months. (2) The excellent and good rate in the experimental and control groups was 90% and 93%, respectively, which showed no significant difference between two groups (χ2=0.007, P > 0.05). (3) The intraoperative blood loss, operation time, and hospital stay in the experimental group were significantly less than those in the control group (P < 0.01); while, the fracture healing time, incidence of complications as well as length of bilateral lower limbs and Harris hip scores at 3 months and 1 year postoperatively did not differ significantly between two groups (P > 0.01). (4) These results suggest that the minimal invasive percutaneous fixation with cannulated compression screws applied in the treatment of young patients with femoral neck fracture exhibits satisfactory efficacy, good reduction, less trauma and rapid postoperative recovery, which is available for all types of young femoral neck fracture.
