Abstract:
Objective To explore the clinical outcome of improved technique of Gamma nail in the treatment of intertrochanteric hip fracture of the elderly patients. Methods From March 2002 to October 2006.39 patients with intertrochanteric hip fracture were operated by improved technique of Gam-ma nail.There were 18 males and 21 females at average age of75.7 years(67_98 years).There were 6 patients with type A1 fracture,24 with type A2 fracture and 9 with type A3 fracture according to AO/ASIF classification.Of all.36 patients(92.3%)had osteoporosis.The operation improvements included the following points:(1)The patients were placed at the lateral decubitus position with the fractured limb on the uppermost,with flexion of knee and hip of 60°.The normal hip and knee were flexed as possible.(2)One-off indirect traction reduction was used after general anesthesia. no requirement of continuous mechanical traction.(3)C-arm image intensifier was employed to obtain normal and lateral projections.Results Of all,35 patients were followed up for a mean period of3 years and 2 months, ranging from 6 months to 5 years and 2 months.Operation data showed incision length of(4.3±1.2)cm,mean opera-tion time of(46±10)minutes,intraoperative bleeding volume of(65±26)ml and intraoperative X-ray exposure of(3.0±2.1)times.Postoperative recovery data showed survival in one-year follow up,with ambulation time of(10.5±3.6)days and fracture union time of(10.9±2.1)weeks.Mean Parker's score wag(6.9±3.2)points 6 months after operation. Conclusions Improved technique of Gamma nail can shorten operation duration,reduce operative trauma and bleeding,reduce X-ray exposure and im-prove success rate of surgery.as facilitates early pest-operative recovery and reduces the perioperative mortality rate of the elderly.
