BACKGROUND:Elderly patients with femoral neck fractures have poor regulatory mechanism, accompanied by a variety of comorbidities and complications, so the treatment and rehabilitation of perioperative femoral neck fracture is very important.
OBJECTIVE:To review the prosthesis selection and complication treatment in perioperative femoral neck fracture in elderly patients.
METHODS:A computer-based research was conducted in PubMed database and CNKI database for the articles published since 2000, the key words were“elderly, femoral neck fracture, perioperative, treatment and rehabilitation, hip fracture”in Chinese and English. The clinical researches were selected. The subjects were the femoral neck fracture patients with the age over 65 years. The review literatures and the literatures with smal cases and old were eliminated, and final y 20 literatures were included for analysis.
RESULTS AND CONCLUSION:Due to the osteoporosis of the elderly patients, the internal fixation often failed. For the Garden Ⅲ and Ⅳ femoral neck fracture patients with the age over 65 years, as long as there is no clear contraindication for surgery, the hip replacement is often used for the treatment. The tolerance of the patients should be accurately evaluated before replacement, and the blood pressure, blood glucose and various medical complications should be control ed;the rehabilitation training after replacement is also essential. The common complications in elderly patients after replacement include stress ulcer, deep venous thrombosis, neuropsychiatric symptoms, urinary tract infections and the surgical infection.

Objective To evaluate the therapeutic effect of percutaneous transhepatic biliary drainage (PTBD) with different approaches in patients with hilar cholangiocarcinoma type Ⅱ-Ⅳ.Methods The short-term clinical effect and longterm survival rate were analyzed retrospectively for a group of 97 patients with hilar cholangiocarcinoma type Ⅱ-Ⅳ receiving PTBD with different approaches,i.e.unilateral and bilateral biliary drainage,each including stent placement and drainage tube implantation.Results No significant difference was found in the decreasing of TBIL and DBIL,the survival rate and survival Curve between unilateral and bilateral biliary drainage.The median survival time was 7.5 months in unilateral and 6.7 months in bilateral biliary drainage,6.0 months in single stent and 6.5 months in single drainage tube,and 4.3 months in bilateral stents,respectively.The post operation complications mainly occurred in single drainage tube.Conclusion Single biliary drainage is able to decrease bilirubin for hilar cholangiocarcinoma type Ⅱ-Ⅳ,while stent implantation should be taken as the first choice.
