| Subject:Collected proximal femoral nail antispirochete surgical treatment of intertrochanteric fracture surgery immediately after surgery and after six months of follow-up X-ray imaging information, summarize and analyze intraoperative calcar reset occurs mechanics spiral blade the impact of complications, while providing reference data and deeper study of bone surgeons.Materials and methods: Statistical retrospective the anti-helix proximal femoral nail surgery 64 cases which in the 2th Hospital of Medical University and take 8 cases because the sample does not meet the pre-set criteria from 2012 to 2014, be excluded, more than 56 cases patients(61-89 years old) were follow-up in 6-10 months, the healing, spiral from the top of the blade position and value(tip- apex distance, TAD). The 56 patients was assessed according to Baumgaetner femoral calcar Reset situations into A(excellent group), B(poor group) groups(assessment methods include the femur from the neck-shaft angle normal or slightly on the anteroposterior X-ray valgus, the lateral X-ray into the angle is less than 20 degrees, the lateral displacement in the lateral X-ray films were less than 4mm is defined as a reset fine), measuring 56 patients after surgery and then six months after the the TAD values TAD statistics mean and mean the difference between the two groups in each period, according to the statistical results observed femoral calcar reset on whether the impact of the displacement of the spiral blade.Result : 56 routine PFNA fixation patients were followed up from 6 to 10 months.HARRIS hip surgery using the grading standard rate of 90.8% excellent. In this study, patients were followed 1/9 cases occur in patients with mechanical complications,8 cases of A group 1 patients, group B. Group B 3 cases spiral blade cut out, cut out the displacement greater than 5mm, including two cases of TAD values less than 23mm(20.2mm, 18.9mm), and another more than one case of 27 mm, is 28.3mm; 2 cases of outward spiral blade transverse displacement greater than 10mm; 2 cases spiral blade has piercing trend towards the direction of the femoral head, respectively, from the articular surface of about 3mm, 4mm;one patient had nail breakage, his TAD is 32 mm,one patient had appeared to spiral blade case articular surface piercing trend away from the articular surface of about 3mm, more than 45 patients healed fractures are not cut out, broken nails, hip function in a good situation.Conclusions: Sorting through the data, draw conclusions, preliminary analysis and statistics can be inferred femoral calcar reset excellent degree have a significant impact on the rate cut spiral blade. When femoral femoral calcar satisfactory reduction, and six months after surgery was difference between the mean of TAD 3.5mm, no serious mechanical complications; when the femur from the reset does not meet the standard, TAD significantly increased the mean difference between the average of 6.1mm spiral blade cut out the trend increased significantly. |
