ABSTRACT

Objective:To explore the classification and treatment strategy of femoral neck fracture combined with ipsilateral intertrochanteric fracture.Methods:A retrospective analysis was performed of the 44 patients who had been admitted to Department of Orthopedics, Liangxiang Teaching Hospital, Capital Medical University from March 2003 to March 2019 for femoral neck fracture combined with ipsilateral intertrochanteric fracture. They were 19 males and 25 females, aged from 37 to 93 years (average, 77.9 years). According to the anatomical location and displacement severity, the femoral neck fractures were divided into 3 types while the intertrochanteric fractures were classified as stable or unstable ones. There were 3 cases of type Ⅰ which were completely extracapsular ones, 31 cases of type Ⅱ which were intracapsular stable ones, and 10 cases of type Ⅲ which were intracapsular unstable ones. Types Ⅰ and Ⅱ fractures were treated with intramedullary fixation, and type Ⅲ fractures with cemented hip hemi-replacement+reduction and fixation of the intertrochanteric fracture with Kirschner wires and steel cables. Recorded were fracture healing time, function of the affected hip and complications.Results:The 44 patients were followed up for at least 2 years. The fracture healing time for the 3 patients with type I fracture averaged 5.6 months (from 4.4 to 6.8 months); their hip function at the last follow-up, evaluated by the Harris scoring system, was excellent in 2 cases and good in one case. For 30 of the 31 patients with type Ⅱ fracture, the fracture healing time averaged 7.2 months (from 5.1 to 9.3 months); their hip function at the last follow-up, evaluated by the Harris scoring system, was excellent in 18 cases, good in 6 cases, fair in 5 cases, and poor in 2 cases, giving an excellent and good rate of 77.4% (24/31). As for complications, withdrawal or cutting-out of the head screw happened in 6 cases, infection in one case and nonunion in one case. In 10 patients with type Ⅲ fracture, the hip function at the last follow-up was excellent in 7 cases, good in 2 cases and poor in one case.Conclusions:For type Ⅰ and type Ⅱ femoral neck fractures combined with ipsilateral intertrochanteric fracture, intramedullary fixation with angulation stability may be a proper choice. For type Ⅲ ones, hip joint replacement should be the first choice.

ABSTRACT

Objective:To investigate the anti-fatigue phenomenon induced by forced swimming in the mice,and to explore the anti-fatigue effect of argininyl fructoyl glucose (AFG) from red ginseng in the mice and its mechanism.Methods:The AFG was extracted from red ginseng.The ICR mice were divided into blank control group,low dose of AFG group (100 mg · kg-1),middle dose of AFG group (200 mg · kg-1) and high dose of AFG group (400 mg · kg-1) (n=20).The mice mere given a forced swimming test after continuous gavage for 28 d.The weights,organ indexes,time of forced swimming,contents of lactic acid (LD),blood urea nitrogen (BUN),hepatic glycogen (Gly) and expressing levels of PGC-1α in gastrocnemius of the mice in various groups were detected.Results:Compared with blank control group,the weights and organ indexes of the mice in low,middle and high doses of AFG groups had no significant differences (P> 0.05).Compared with blank control group,the time of forced swimming,contents of Gly and expressing levels of PGC-1α of the mice in low,middle and high doses of AFG groups were significantly increased (P<0.05 or P<0.01) in a dose-dependent manner.Compared with blank control group,The contents of LD and BUN in serum of the mice in low,middle and high doses of AFG groups were significantly decreased (P<0.01).Conclusion:AFG has anti-fatigue effect in mice,and its mechanism may be related to energy metabolism.

ABSTRACT

Objective To retrospectively analyze the results of treatment with Asian proximal femoral nail anti rotation intramedullary nail (PFNA Ⅱ) in senile patients with unstable intertrochanteric femoral fractures. Methods 1 06 cases of unstable intertrochanteric femoral fracture with internal fixation of PFNAⅡ were analyzed retrospectively,and the treatment effect was observed.Results 1 06 cases were followed -up(mean 1 3.5 months, ranged 1 0 -22 months).Bone union occurred in all cases,average fracture healing time was 3.8 months.The average operation time was 48 minutes,the average volume of blood loss was 1 06mL.The hip functions were analyzed using Harrison score.And found 80 excellent cases,1 4 good cases,1 2 fair cases,with 88.7% of excellent and good rate. Conclusion For the senile patients of unstable intertrochanteric femoral fractures,PFNAⅡ has the biomechanical advantages of intramedullary fixation,small trauma,short operation time,reliable internal fixation,early functional exercise,low incidence of complications,significant functional recovery,and is a preferred treatment option.
