OBJECTIVE@#To investigate the effect of different postures on direct anterior approach(DAA) total hip arthroplasty.@*METHODS@#Total of 94 patients who underwent DAA total hip arthroplasty from July 2016 to June 2020 were retrospectively analyzed. They were divided into two groups according to different positions during the operation, including 45 cases in lateral position and 49 cases in supine position (with the aid of stent). The general data such as gender, affected limb, body mass index(BMI), incision length, operation time, intraoperative bleeding volume, drainage volume 24 hours after operation, hemoglobin difference before and after operation, first landing time after operation, postoperative hospitalization time, postoperative complications, visual analogue scale(VAS) at 1 day, 1, 2 weeks, 1, 3 and 6 months after operation, Harris score at 1, 2 weeks, 1, 3 and 6 months after operation were observed and compared between the two groups.@*RESULTS@#Patients in both groups were followed up for 6 to 12 months with an average of (8.31±2.22) months. There was no significant difference between two groups in gender, affected limb, age, height, weight, body mass index(BMI), preoperative VAS score and preoperative Harris score(P>0.05). The incision length, operation time, intraoperative bleeding volume, 24-hour drainage volume, hemoglobin difference before and after operation, first time to the ground and postoperative hospitalization time of patients in supine position (assisted by stent) group were all better than those in lateral position group(P<0.05);There was no significant difference in the number of blood transfusions during and after operation(P=0.550). There was no significant difference in anteversion angle and abduction angle in the supine position(with the aid of stent) group during and after operation (P=0.825, P=0.066);There was significant difference in anteversion angle and abduction angle in the lateral position group during and after operation(P<0.05). VAS of patients in supine position (assisted by stent) group were lower than those in lateral position group at 1 day, 1, 2 weeks and 1 month after operation(P<0.05), and there was no statistical difference between two groups at 3 and 6 months after operation(P>0.05). Harris scores of patients in supine position(assisted by stent) group were higher than those in lateral position group at 1 week, 1 month and 3 months after operation(P<0.05), and there was no significant difference between two groups at 6 months after operation(P>0.05).@*CONCLUSION@#Compared with the lateral position, the supine position DAA total hip arthroplasty has the advantages of small incision, short operation time, less bleeding, early landing time, short hospitalization time, and small intraoperative acetabular cup position judgment error. It has the advantage of fast postoperative recovery, but the recovery of hip joint function is the same after 6 months.

<p><b>OBJECTIVE</b>Through an analysis of the effect of PKP (percutaneous kyphosis plasty) for aged osteoporotic spinal multiple fracture to demonstrate the importance of the selection of responsible veterbal body.</p><p><b>METHODS</b>Twenty-four consecutive procedures were performed in 19 aged patients with osteoporotic spinal compression fractures from May 2004 to October 2007. The 24 responsible veterbal bodies were confirmed by the manifestations of MRI, X-ray, physical examination before the procedures. Established work path through hibateral vertebral arch, put into saccule, poured in bone cement under X-ray perspective. To observe the condition about symptom improving, fractured reduction and complications after operation.</p><p><b>RESULTS</b>The operations were successfully completed and the pain released obviously at 2 days after operation. The patients can walk next day after operation and no complication found. The mean loss percent of the anterior and middle vertebal heights were respectively (34.22 +/- 11.51)% and (26.53 +/- 11.61)% before operation,postoperative were respectively (13.21 +/- 11.43)% and (15.10 +/- 6.50)%. The mean kyphosis corrected from (24.50 +/- 3.10) degrees to (8.70 +/- 4.30) degrees; the VAS scores decreased from 83.00 +/- 6.00 to 27.00 +/- 5.00. There was significant difference between before and after operation (P < 0.01).</p><p><b>CONCLUSIONS</b>PKP for aged osteoporotic spinal multiple fractures by selecting true veterbal body has satisfactory clinical efficacy. We should emphasize the importance of the selectivity of responsible veterbal body in the procedures. It needs three essential elements: (1) Obviously spinous process tenderness and rap pain. (2) X-rays showed veterbal body compression fracture; MR showed low signal in veterbal body by T1WI, and high signal by T2WI, STIR. (3) The manifestation of radiology can be explained clearly by clinical symptomes arid signs.</p>

<p><b>OBJECTIVE</b>To explore the effect of arterial perfusion of marrow multifunctional stem cells (MFSC) in treating femoral head necrosis and its mechanism.</p><p><b>METHODS</b>The rabbit model of femoral head necrosis was established by large dose of methyl-prednisone through Shwartzman response. Bone marrow was extracted from femoral bone of model rabbit and isolated in vitro for culturing and proliferating MFSC. The experimental rabbits were randomly divided into 4 groups, treated with normal saline (A), Salvia + urokinase (B), MFSC (C) and MFSC + Salvia + urokinase (D), respectively, they were sacrificed in batches at 2 and 4 weeks after treatment, and changes in various parameters, including molybdenum target roentgenogram, routine pathology with HE staining, tetracycline labeled fluorescent microscopy and ultrastructure alteration by scanning electron microscope (SEM), were observed.</p><p><b>RESULTS</b>Typical appearance of femoral head necrosis was shown in the successfully modeled rabbits. Two and 4 weeks after treatment by high selective drug via medial and lateral femoral circumflex arterial perfusion, the X-ray examination showed significant improvement of bone density; pathohistologic manifestation showed decrease of empty bone lacuna, increase of osteoblast and new bone formation; tetracycline fluorescent labeled microscopic picture showed bright fluorescent band of increased osteoblasts in necrosis repairing region with widened border; SEM displayed irregularly arranged fibrosis in necrosis region, abundant organelles in osteoblasts with few empty bone lacuna. The above-mentioned improvement was more significant in rabbits treated by MFSC.</p><p><b>CONCLUSION</b>High selective femoral drug arterial perfusion in treating femoral head necrosis could accelerate the process of revascularization and re-ossification in rabbits. As compared with Salvia, MFSC showed quicker and more potent effect.</p>
