Objective To compare the curative effects of intertrochantefie fractures in aged by two operative methods. Methods 85 cases of elderly patients suffered from intertrechanteric fractures were retrospectively ana-lyzed. Out of the 85 cases,45 cases were treated with dynamic hip screw(DHS) and 40 cases were fixed with Gamma nails. The curative effects and complications were compared simultaneously. Results The total excellent rate was 83.5% in 85 patients,the rates of DHS and Gamma nails group were 77. 8% and 90% (X2 = 2. 84, P 0. 05), re-spectively. The operative time (66. 4 ± 19. 4)min in DHS group were less than the Gamma nail group (875 ± 25.5) rain (t=2. 451 ,P < 0. 05), but the length of surgical incision (19. 6± 5. 1)cm greater than the Gamma nail group (10. 3 ± 4. 7) cm(t = 2. 501, P < 0. 05). The complications of DHS group (11.1%) were significanfly higher than that of Gamma nail group(2. 5%) (X2 =3.94,P<0. 05). Conclusion As long as the physical condition can toler-ate,surgery recommend the use of DHS and Gamma nail surgical techniques in aged patients with intertrechanteric fractures.

Objective To study curative effect of core decompression and autologous bone marrow stem cell transplantation combined with traditional Chinese medicine in the treatment of early femoral head necrosis (ANFH).Methods 30 patients with femoral head necrosis treated by different methods were divided into 3 groups: core decompression A group) 10 cases(12 hips) ;core decompression pus stem cells transplantation(B group) 10 cases(13 hips) ;core decompression pus stem cells transplantation combined with traditional Chinese medicine(C group) 10 ca-ses( 10 hips) ;The X-ray 、CT MRI、Harris score( HHS) .curative effect were observed.Results The phase of Ⅰ,Ⅱ,Ⅲ,in 3 groups didn't appear deformation and collapse at 3,6,12 months;The score of Harris after 12 months 93 points were higher than that preoperatively 57.5 points(χ 2= 5.81 ,P<0.05) ;The signal ratio of femoral head volume in MRI was 42% before treatment,disappearance of femoral head necrosis after treatment;Total curative effect of B,C group,werehighter than that Agroup(χ2 =3.81,χ2 =3.98,P<0.05).Conclusion The operative treatment of ANFH with core decompression and stem cells transplantation combined with traditional Chinese medicine had the advantage of minimal damage,simplicity,accuracy,and effectiveness.

Objective To study the characteristics and therapeutic effect of femoral neck fractures in young adults by many treatment methods. Methods 32 cases with femoral neck fractures in young adults 21-50 years. Using of tube decompression of the femoral head involvement, fracture of drug injection, intravenous drip and so many ways of delivery, to regular observe their fracture healing and clinical efficacy. Results All 32 cases with femoral neck fracture postoperative follow-up 5-9 months to obtain bone healing;Follow-up to 1 year of hip joint function was basically normal,non-femoral head necrosis. Follow-up to 3 years,32 cases in 26 cases of excellent,good in 5 and poor in example 1. Example 1 due to poor weight -bearing walking premature and older (50 years) appear avascular necrosis of femoral head,the total hip arthroplasty. Conclusion The joint methods have an exact effect in patirnts with femoral neck fracture.The advantages were easy to operate,less trauma and fewer complications,fast recovery ,easy to promote.
