Objective:A retrospective study of treatment of intertrochanteric fractures of elderly Hip Arthroplasty with the "8" Word Cerclage Cable to bind the small tuberosity, and reestablish the femorol calcar.Materials and Methods:A. Case InformationIn this study, cases are selected from the Jilin University, China-Japan Friendship Hospital (or the Third Clinical College of Norman Bethune Medical University), from January 2004 to February 2009 for senior citizens unstable intertrochanteric fracture artificial prosthesis replacement surgery 39cases of patients (39 hips),According to Evans-Jensen type,those fracture are all unstable fracture,which 8 cases of type III,17 cases of type IV ,14cases of type V .15 cases were male, 24 cases were female.Age between 71 and 92 years old,average 77.2 years old.Causes injury:31cases of accidental falling dowm,8 cases of car accident.21 cases of the left side,18 cases of the right side.All the fractures were fresh fracture.The time from Injury to operation was 1-5 days,average 3 days.32 cases of patients had internal diseases,which 16 cases had 1 kinds of diseases,9 cases had 2 kinds of diseases,7 cases had 3 kinds of diseases.The common diesesaes are Hypertension,Diabetes,Cardia insufficiency, Chronic bronchitis,Cerebral thrombosis.The time of postoperative follow-up was between 3 months and 31 months,average 18 months.B. Treatment(1)Improve the relevant inspection and consult the medicine, anesthesia doctor(2)Surgery①Prosthesis selection:30 cases of using bipolar femoral head prosthesis,9 cases of using total hip prosthesis②Operative incision and approach selection:all use hip lateral approach③use "8" Word Cerclage Cable to bind and fix large and small trochanter,and reestablish the anatomy of calcar femorale:Intraoperative exposure of large and small tuberosity, T-shaped cut-off the capsular, then carefully exodus the femoral head, neck together ,cut-off neck in 1.5-2 cm above the small tuberosity.If the degree of femoral neck fracture in a serious smash,tuberosity fracture displacement would significantly increase because of external force of exodus the femoral head, neck,so Is not to get out of the femoral head from the acetabulum, but before the small tuberosity on the cut-off neck 1.5-2 cm,then after the femoral head out to make large and small tuberosity restoration, and reestablish the anatomy of calear femorale.Because it is in a small tuberosity femoral neck cut off more than 1.5 centimeters, so that retained a considerable length of the neck ring of cortical,make the ring cortex of the neck to the medullary cavity of about 0.5-0.8 cm inserted at trochanteric fracture,So that the neck and trochanteric fracture overlap of about 0.5-0.8 cm,and increase the local structure of the stability of bone,bone overlap helps fracture healing.Cases in this group are elderly patients,osteoporosis is more osteoporosis.Opening cut in the neck cavity when a smaller force, not to make the replacement fracture displacement,after use the pulp canal drill to expand the upper chamber,use the little smaller pulp canal drill to expand the trochanteric,and make sure the smaller pulp canal dill in the upper chamber and do not pull it out temporarily.Check the situation of the replacement of the fracture again,make sure it is anatomic reduction.Will be large and small tuberosity together with the neck ring of cortical bone be a fixed bundle.Make sure the restoration of the calear femorale from the anatomical structure and stability.Surgery is anatomic reduction of fracture.④Choose a suitable necks of the central head,suture joint capsule and the external rotation muscles, layer-by-layer closure of incision.C.After operation routine use of antibiotics and other drugs in patients with functional exercise guidance.Results:our group of 39 cases, none of patients dead in hospital .The time of weight-bearing walking is 10-14 days(average 12 days). All of the patients were followed up for 3-31 months (average 18 months), 3 patients died because of other disease. The following-up x-ray films showed that fractures healed well and no wires were broken. All of the patients could take care of themselves. According to harris hip score, the function of hip joint excellent 14cases, good 18 cases, benign in 5 cases and poor in 2 case.Conclusion:Hip replacement is widely used to treat with intertrochanteric fractures of the elderly patients. Whether hip replacement could meet the anatomy and biomechanics requirements at the same time is the key point to ensure the stability of the joint operation, and the early activities of getting out of bed postoperatively. We used "8" Word Cerclage Cable to get the anatomic reduction of fracture and restore the stability of femora calcar by the fixation of prosthesis and cement in bone marrow cavity and "8" Word Cerclage Cable Many complications were avoided successfully at the same time, such as prosthesis subsidence , coxa vara and so on. The patients also could do early exercise, which helps to improve the general situation and prevent long -term complications of bed rest.
