| 1 | Direct anterior total hip arthroplasty: Literature review of variations in surgical technique显示文摘The direct anterior approach to the hip has been suggested to have several advantages compared to previously popular approaches through its use of an intra-muscular and intra-nervous interval betweenthe tensor fasciae latae and sartorius muscles. Recent increased interest in tissue-sparing and minimallyinvasive arthroplasty has given rise to a sharp increase in the utilization of direct anterior total hip arthroplasty. A number of variations of the procedure have been described and several authors have published their experiences and feedback to successfully accomplishing this procedure. Additionally, improved understanding of relevant soft tissue constraints and anatomic variants has provided improved margin of safety for patients. The procedure may be performed using speciallydesigned instruments and a fracture table, however many authors have also described equally efficacious performance using a regular table and standard arthroplasty tools. The capacity to utilize fluoroscopy intraoperatively for component positioning is a valuable asset to the approach and can be of particular benefit for surgeons gaining familiarity. Proper management of patient and limb positioning are vital to reducing risk of intra-operative complications. An understanding of its limitations and challenges are also critical to safe employment. This review summarizes the key features of the direct anterior approach for total hip arthroplasty as an aid to improving the understanding of this important and effective method for modern hip replacement surgeons. | Keith P Connolly Atul F Kamath | 2016 | World Journal of Orthopedics2016，7，1： | 33 |
| 2 | Direct anterior total hip arthroplasty:Comparative outcomes and contemporary results显示文摘Direct anterior total hip arthroplasty has become increasingly more popular among arthroplasty surgeons,in large part due to the use of an intramuscular interval and desire to reduce soft tissue damage.Several studies have now been published comparing the anterior intramuscular to other commonly used approaches,and many studies have published complication rates on large series of patients.Review of comparative studies indicates direct anterior hips tend towards shorter hospital stays and high rates of patients discharged to home.Although some studies show evidence of early benefit in functional outcomes,there is no strong evidence that the anterior approach provides any long term functional improvements compared to other approaches.Additionally,evidence to support reduced damage to soft tissue may not translate to certain clinical significance.Rates of intra-operative femur fracture,operative time and blood loss rates are notably higher for those developing familiarity with this approach.However,when surgeons have performed a modest number of procedures,the complication rates tend to markedly decrease in most studies to levels comparable to other approaches.Accuracy of component positioning also favors the anterior approach in some studies.This review summarizes the available literature comparing the direct anterior to other approaches for total hip arthroplasty and provides a comprehensive summary of common complications. | Keith P Connolly Atul F Kamath | 2016 | World Journal of Orthopedics2016，7，2： | 14 |
| 3 | Stratification of outcomes for mucinous appendiceal adenocarcinoma with peritoneal metastasis by histological grade显示文摘AIM To investigate the importance of a three-tiered histologic grade on outcomes for patients with mucinous appendiceal adenocarcinoma(MAA).METHODS Two hundred and sixty-five patients with MAA undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy were identified from a prospective database from 2004 through 2014. All pathology was reviewed by our gastrointestinal subspecialty pathologists and histological grade was classified as well-differentiated, moderately differentiated, and poorly differentiated. Survival analysis was performed using Cox proportional hazards regression.RESULTS There were 201(75.8%) well-, 45(16.9%) moderatelyand 19(7.2%) poorly-differentiated tumors. Histological grade significantly stratified the 5-year overall survival(OS), 94%, 71% and 30% respectively(P < 0.001) as well as the 5-year disease-free survival(DFS) 66%, 21% and 0%, respectively(P < 0.001). Independent predictors of DFS included tumor grade(HR = 1.78, 95%CI: 1.21-2.63, P = 0.008), lymph node involvement(HR = 0.33, 95%CI: 0.11-0.98, P < 0.02), previous surgical score(HR = 1.31, 95%CI: 1.1-1.65, P = 0.03) and peritoneal carcinomatosis index(PCI)(HR = 1.05, 95%CI: 1.02-1.08, P = 0.002). Independent predictors of OS include tumor grade(HR = 2.79, 95%CI: 1.26-6.21, P = 0.01), PCI(HR = 1.10, 95%CI: 1.03-1.16, P = 0.002), and complete cytoreduction(HR = 0.32, 95%CI: 0.11-0.92, P = 0.03). Tumor grade and PCI were the only independent predictors of both DFS and OS. Furthermore, histological grade and lymphovascular invasion stratified the risk of lymph node metastasis into a low(6%) and high(40%) risk groups. CONCLUSION Our data demonstrates that moderately differentiated MAA have a clinical behavior and outcome that is distinct from well-and poorly-differentiated MAA. The threetier grade classification provides improved prognostic stratification and should be incorporated into patient selection and treatment algorithms. | Travis Edward Grotz Richard E Royal Paul F Mansfield Michael James Overman Gary N Mann Kristen Ashlee Robinson Karen A Beaty Safiea Rafeeq Auerlio Matamoros Michelle W Taggart Keith Francis Fournier | 2017 | World Journal of Gastrointestinal Oncology2017，9，9： | 2 |
