An approach to fractures of the midface: An interactive tutorial

Purpose: To describe an educational computer aided instruction program dealing with diagnosis and classification of facial fractures. Methods: A program was created for use on Macintosh computers using a graphic presentation package. This program allows for the display of high resolution digitized radiographic images and illustrations, along with integrated voice and text information. Users can interact with the program to review complex concepts or study additional cases. Case material was obtained from selected high quality plain radiographs and computed tomography (CT) scans obtained in the trauma center of one institution, and was scanned on a high resolution digital scanner with image parameters optimized for viewing on the Macintosh high resolution color monitor. Results: The program has been installed in the computer aided instructional laboratories or trauma centers at The University of Texas Health Science Center, Houston; The University of Alabama, Birmingham; Emory University School of Medicine, Atlanta, Georgia; and The University of North Carolina, Chapel Hill. The program is available to radiology residents and medical students rotating on the trauma radiology services at these institutions. Completion of the program requires 30–45 minutes. Conclusion: Based on our initial experience, the program has been used by residents in the training programs of all institutions with favorable results.     

OUTCOME AFTER FRACTURES OF THE FEMUR IN PAGET'S DISEASE

We reviewed ninety-three patients who had one hundred and seven complete fractures of the femur between them and were treated over a twenty-five year period in Western Australia and South Australia. Operative surgical management of complete fractures in the middle and distal thirds was usually successful. In contrast, fractures proximal to the middle third were regularly associated with non-union, implant failure and requirement for revision surgery. In view of this significant difference in outcome after fracture of the pagetic femur in different sites, a comprehensive surgical management strategy is recommended in order to avoid complications.     

Quality of life as outcome in the treatment of osteoporosis: The development of a questionnaire for quality of life by the European foundation for osteoporosis

The morbidity of osteoporosis is caused by fractures. Vertebral fractures lead to pain and disability and a decrease in quality of life. A Working Party of the European Foundation for Osteoporosis has developed a specific questionnaire for patients with established vertebral osteoporosis. This questionnaire is intended for use in clinical trials. The questionnaire consists of questions and visual analogue scales in the following domains: pain, activities of daily living, jobs around the house, mobility, leisure and social activities, general health perception and mood. The questionnaire has been translated from English into French, German, Italian, Hebrew, Swedish and Dutch. The questionnaire is currently being validated in a multicentre study involving patients with stable osteoporosis and control subjects. Preliminary results indicate that the reproducibility is sufficient and that the questionnaire is able to discriminate between patients with vertebral osteoporosis and control subjects.     

股骨多段闭合骨折病人术前凝血功能的变化

目的 探讨股骨多段闭合骨折病人术前凝血功能的变化。方法 选择创伤股骨多段闭合骨折后当天入院的病人20例,年龄19-45岁,ASA Ⅰ级,为试验组(Ⅰ组);选择健康成年人15人,年龄21-39岁,作为对照组(Ⅱ组);Ⅱ组于清晨空腹采上肢静脉血标本,Ⅰ组病人入院后于骨折的第2天、第6天(手术当天清晨)空腹采上肢静脉血样本,检测血栓弹力图(TEG)指标[R时间、K时间、α角、血栓最大幅度(MA)、血栓硬度(G)]、D-二聚体浓度(D-Di)、血小板计数(PLC)及血小板聚集率(PAgR)的变化。结果 Ⅱ组TEG指标、D-Di、PLC及PAgR均在正常范围。与Ⅱ组比较,Ⅰ组骨折后第2天,K时间缩短(P<0.05),α角、MA、G及D-Di增高(P<0.01);骨折后第6天,R时间缩短(P<0.05),α角、MA、G、D-Di、PLC及PagR增高(P<0.01)。与骨折后第2天比较,Ⅰ组骨折后第6天MA、G、PLT及PAgR增高(P<0.05或0.01)。结论 病人创伤骨折后凝血功能24 h内增强,随时间的延长至术日呈高凝状态,应加强术中管理,并采取相应措施预防术中静脉血栓的发生。

微创内固定系统治疗复杂股骨转子部骨折的初步报告

目的探讨微创内固定系统(LISS)治疗复杂股骨转子部骨折的可行性、手术技术及指征,并总结其近期临床治疗效果。方法自2005年6月～2006年5月,应用LISS治疗复杂股骨转子部骨折12例。骨折采用AO分类法,其中转子间骨折5例：31-A2．2型2例,31-A2．3型2例,31-A3．3型1例；转子下骨折7例：32-A3．1型1例,32-B1．1型3例,32-B2．1型1例,32-B3．1型2例。记录手术时间、术中出血量、术后住院时间,术后观察有无感染、下肢深静脉血栓、心肺疾患、应激性溃疡等并发症。术后1、2、3、6、12个月时常规随访。结果手术时间50～90 min,平均65 min；出血量50～400 mL,平均142 mL,术后住院时间6～15 d,平均9．3 d。无死亡病例。所有患者均未出现切口感染、下肢深静脉血栓、术后心肺疾患、应激性溃疡等并发症。12例均获得3～14个月(平均7．2个月)随访。10例在术后3个月复查骨折时达到临床愈合,1例假体周围骨折术后4个月、1例病理性骨折术后6个月达到临床愈合。所有患者在最后一次随访时均无骨折再移位、髋内翻畸形、内固定切出、内固定失败及股骨头坏死。结论微创反向使用股骨LISS从生物力学和解剖结构上都能满足股骨近端骨折内固定要求,并具有创伤小、操作简便、固定可靠、安全性高、并发症少的特点,尤其适用于老年人合并内科疾病、骨质疏松较重的转子间骨折及复杂的股骨近端骨折。熟练掌握间接复位技术,正确放置A孔导针,避免过早负重是手术成功的关键。
