Objective To identify an evidence-based treatment for an elderly patient with intertrochanteric fractures. Methods Clinical problems were presented on the basis of the patient’s conditions, and evidence was collected from the NGC (2000 to 2009), The Cochrane Library (Issue 4, 2009), TRIP Database, PubMed (1966 to 2009) and CBM (1978 to 2009). Treating strategies were formulated in terms of the three-combination principle (best evidence, the doctor’s professional knowledge and the patient’s desire). Results Three guidelines and sixteen studies were included. The current evidence indicated that surgery was the preferred solution to intertrochanteric fractures of the elderly patient. The sliding hip screw (SHS) appeared superior to others. There was insufficient evidence to support the routine use of closed suction drainage in orthopedic surgeries. Early surgery was associated with shorter hospital stay and improved mortality. Antibiotic prophylaxis significantly reduced infections. In order to lower the risk of venous thromboembolism, pharmacological prophylaxis should be carried out when the patient was admitted to hospital and be assisted with mechanical prophylaxis after surgery. Nutritional supplementation was conducive to the recovery of the patient. Rehabilitation ought to be performed as soon as possible. Considering the patient’s condition, the treatment option was established according to the available evidence and guidelines. Short-term follow-up showed a good outcome. Conclusion Through the evidence-based method, an individual treatment plan could obviously improve the treatment effect and prognosis.
Objective To evaluate the effect of composite (bFGF/PDPB) of basic fibroblast growth factor（bFGF） and partially deproteinized bone (PDPB) on the repair of femoral head defect. Methods Forty-eight femoral heads with defect derived from 24 New Zealand rabbits were divided into 3 groups at random, which were implanted with bFGF/PDPB(group A), PDPB(group B) and nothing(group C) respectively.The rabbits were sacrificed at 2,4,and8 weeks after operation, and then the femoral heads were obtained. The specimens injected with Chinese ink were created. Then X-ray examination, histopathological and morphological examination of blood vessel, and image analysis were made. Results The bone defects healed completely 8 weeks after operation in group A. The implants in the repaired tissue were not substituted completely in group B. The bone defects did not heal completely in group C. Two weeks after operation, affluent newly formed vessels were seen in repaired areas in groupA. No significant difference between group A and group B was observed 8 weeks after operation. In group C, newly formed vessels were scarce 2, 4, and 8 weeks after operation. There were 3 sides rated excellent, 2 good and 1 fair in group A; 1 excellent, 2 good, 2 fair and 1 poor in group B; and 1 fair and 5 poor in group C according to the X-ray evaluation 8 weeks after operation. Eight weeks after operation, the volume fraction of bone trabecula in repaired tissue was higher in group A than that in group B (Plt;0.05), and the fraction in group C was thelowest among the 3 groups (Plt;0.05). Conclusion The composite ofbFGF and PDPB can effectively promote the repair of femoral head defect of rabbit.
Objective To explore the effect of minimally invasive and mini-incision surgery (MIS) in total hip arthroplasty (THA) on late osteonecrosis of femoral head (ONFH). Methods From March 2003, Eighteen patients (22 hips) with ONFH underwent MIS in THA. Their ages ranged from 24to 57 years, including 13 males and 5 females. The mean body mass index ranged from 17.1 to 30.1(24.6 on average). The Harris hip score was 46 points before operation. Modified posterior-lateral approach was adopted, and the MIS THA was performed by cementless prosthesis. As a comparison, 18 patients (22 hips) were performed by conventional THA at the same period. The data, including bleeding volume during operation, incision length, operative time, and postoperative function recovery, were compared. Results Follow-ups were done for 6 to 20 months (11 months on average). Dislocation occurred in one patient that underwent conventional THA 2 days after operation. No complication occurred in MIS THA group. The incision lengths ranged from 8.7 to 10.5 cm (9.3 cm on average) in MIS THA group, being statistically different (Plt;0.01). There was no significant difference in Harris scoring of the function between the two groups both before the operation and after the operation (Pgt;0.05). The operative time was almost the same, but the bleeding volume in MIS THA group was less (Plt;0.05). The function recovery was faster in MIS THA group.Conclusion The MIS THA is an alternative to the treatment of late ONFH. The advantages of MIS THA are fewer trauma, less bleeding volume, and faster recovery. The MIS THA should be performed by surgeons with rich experiences in THA and hospitals with necessary instruments.
T ree cases of sarcomas of theJ we femur were treated by region-a?ir? ation with overdosage of me-chlorethamine for 3 weeks and there-after a high amputation was done,and the distal leg was replantedwith the length that the anklewould act as a knee joint and thefoot pointing backword. Follow-upfor 1 -5 years discovered no me-tastasie of the tumor and the artifi-cial limb showed a better function.
Objective To evaluate the effect of the treatment of necrosis of femoral head with the free vascularized fibula grafting. Methods From October 2000 to February 2002, 31 hips in 26 patients with ischemic necrosis of the femoral head were treated with free vascularized fibula graft. Among these patients, 21 patients (25 hips) were followed up for 6-18 months(12 months on average). According to Steinberg stage:Ⅱ period, 5 hips;Ⅲ period,8 hips; Ⅳ period, 12 hips.Results Among 25hips, their Harris Hip Score at all satges were improved during the follow-up. The symptom of pain diminished or disappeared after operation. The patient’s ability to work and live was notlimited or only slightly limited during the follow-up. Radiographic evaluation showed that most femoral heads improved (18 hips) or unchanged (6 hips) and only oneworsened.Conclusion The free vascularized fibular grafting is a valuable method for femoral head necrosis. With this method, we can prevent or delay the process of the disease.

Forty cases of intertrochanteric fractures of femur were treated with percutaneous nonmetallic external fixator. The patients were followed up for 6 months to 3 years, and the fractures were all united without coxa vara or shirtening deformities. There was no mortality in this series. This method had the advantages ofbeing simple, save time and effort, less traumatic and early ambulation. The design of the apparatus tallied with the biomechanics of the neck and shaft of the femur.
