RESUMO

<p><b>OBJECTIVE</b>To evaluate the efficacy of arthroscopic surgery in inflammatory hip arthritis.</p><p><b>METHODS</b>A retrospective clinical study was conducted inspecting 40 hips in 36 patients of inflammatory arthritis. There were 17 cases of ankylosing spondylitis, 11 cases of rheumatoid arthritis, and 8 cases of psoriatic arthritis. The joints were irrigated and the inflamed tissues were debrided with anthroscopy. The patients were followed up with Harris hip score, Oxford hip score, Visual Analog Scale (VAS), and magnetic resonance imaging (MRI). Statistical analysis was performed using Student t test.</p><p><b>RESULTS</b>All of the 36 cases were followed up for 46-103 months, averaging 67.2±8.4 months. Harris and Oxford scores increased from 66.9±12.1 and 69.4±16.4 before operation to 78.4±19.3 and 80.2±18.8 after operation, respectively (P<0.05). VAS score decreased from pre-operative 8.5±2.5 to post-operative 7.2±2.5 (P<0.05). All the patients showed improved joint range of motion. MRI revealed alleviation of hip synovitis. The results were classified as excellent in 8 patients, good in 17 patients, fair in 8 patient, and poor in 3 according to Harris hip score. Twenty-seven patients were satisfied with the operative outcomes as they regained normal daily activities.</p><p><b>CONCLUSIONS</b>Arthroscopy-assisted joint debridement and synovium resection is an effective procedure for hip lesion in inflammatory arthritis. The inflammatory lesion might be thereby controlled and the symptoms be relieved.</p>

RESUMO

<p><b>BACKGROUND</b>Most of endovascular stent-graft modifications to preserve side branch must be customized according to extensive pre-operative assessment, which may not be possible in many hospitals and emergency settings. The study was to develop a novel stent-grafts system that would allow in situ "fenestration", with less reliance on preoperative imaging.</p><p><b>METHODS</b>The magnitude of pressure difference (PD) between left subclavian artery (LSA) and aortic arch were measured in 12 experimental pigs. Changes of PD before and after LSA was covered were analyzed respectively. The novel stent graft was made by multi-dimensional and multiple textiles forming technology. According to the PD measurement in pigs, we evaluated the feasibility of the stent-graft in a mock circulation system.</p><p><b>RESULTS</b>In pigs, the blood pressure of aortic arch was significantly higher than that of LSA after it was covered (P < 0.001) and PD was (42.78 ± 5.17) mmHg. After target vessel was covered and when PD between the LSA and aorta reached the magnitude measured in pigs, contrast media oozed from the cranny of graft to the LSA, which was generated by sliding and deformation of yarns of novel stent-graft.</p><p><b>CONCLUSIONS</b>The study proposes the design of pressure difference-induced perforation aortic stent-grafts system and verifies that the PD between LSA and aortic arch is high enough to allow in situ "fenestration" by stent graft made by multi-dimensional and multiple textiles forming technology.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the methods of reduction and stable fixation for the treatment of calcaneus fracture involving posterior subtalar articular facet.</p><p><b>METHODS</b>From September 2004 to September 2008, 31 cases(38 feet) of calcaneus fracture involving posterior subtalar articular facet were treated with open reduction and plate fixation through L incision. There were 24 males and 7 females, with an average age of 39.6 years ranging from 20 to 65 years. All patients underwent systematic CT-scan with coronal and horizontal images and sagittal reconstruction. The classification of the fractures by the Sanders scale showed that there were 22 of type II,14 of type III, 2 of type IV.</p><p><b>RESULTS</b>All cases were followed up for from 12 to 36 months with an average of 25 months, and all the fractures healed without skin flap necrosis. According to the Maryland foot scoring, the total score was (96.2 +/- 8.8) on average, the results were excellent in 32 feet, good in 4 feet, fair in 2 feet.</p><p><b>CONCLUSION</b>The replacement of the posterior articular facet by X-ray control of Broden and open reduction and internal fixation with calcaneus plate and Schanz-Screw during the operation can keep stable of articular facet, and promote early rehabilitation of calcaneus fracture affected with subtalar joint.</p>
