Ilizarov牵伸技术在外伤性垂足治疗中的应用

[目的]探讨应用Ilizarov牵拉技术治疗外伤性垂足的疗效。[方法]自2004年12月~2006年2月采用Ilizarov技术治疗8例外伤性垂足患者,其中男5例,女3例;年龄28~52岁,平均34.6岁。垂足产生原因小腿胫前外侧肌群断裂或缺损3例,小腿骨筋膜室综合征2例,腓总神经损伤2例,股骨髁上骨折并腘动脉断裂1例。踝关节强直范围为跖屈50°~65°。术中将准备好的牵拉架套入小腿及足部的相应位置。在钢环对应平面交叉穿入2mm克氏针并固定于Ilizarov牵拉架上,术后3~5d开始以1~2圈/d,4次/d的速度旋转踝关节前、后方的调节螺纹杆,使足环带动患足逐渐背伸,使垂足畸形逐渐得以纠正。当垂足提拉达到或超过中立位后停止牵拉,但继续使用牵拉架固定2~3个月以巩固疗效。[结果]所有患者均获随访,随访时间为10~21个月,平均12.5个月。患足均矫正至中立位,有3例患者踝关节可主动背伸至10°,行走功能均良好。有1例患者1个针道发生感染,经输用抗生素,加强针道护理,保证针道引流通畅,感染逐渐控制。无1例发生皮肤坏死、神经、血管损伤等并发症。全部患者垂足畸形无复发。[结论]应用Ilizarov牵拉技术治疗外伤性垂足较以往的治疗方法有明显的先进性,值得推广。     

手部关节损伤的治疗

目的 通过对手部关节损伤治疗方法的对比和随访观察，总结出各种方法的优缺点，并指出相对较好的治疗方法。方法 1980～2002年对手部关节损伤进行各种手术治疗，通过观察病人术后关节的活动度、肿胀、疼痛、畸形及捏力的改善等项目，评价哪种方法相对更好。结果 通过对各种数据的测量比较，特别是关节活动度的改善情况，认为人工关节置换是所有治疗方法中相对最好的。结论 尽管人工关节置换也有不少缺点，但随着新材料的不断应用和设计的不断改进，其治疗效果将越来越好。     

首次CT检查阴性的颅脑损伤54例临床分析

目的分析颅脑损伤首次CT检查阴性而复查CT阳性的表现和原因。方法通过对首次CT检查阴性而复查CT阳性的54例颅脑损伤患者（研究组）的临床资料进行回顾性分析总结,并与同期收治的325例首次CT及复查CT均为阴性的颅脑损伤患者（对照组）作比较。结果研究组首次CT检查阴性而复查CT阳性表现为迟发性血肿、脑挫裂伤、脑积水、硬膜下积液、弥漫性脑肿胀、外伤性脑梗塞等,可由不同原因引起。结论熟悉本类颅脑损伤首次CT检查阴性,而复查CT阳性的表现及原因,对于指导检查及治疗,改善病人预后有重要意义。

无骨折脱位型颈脊髓损伤再手术原因分析

目的:探讨无骨折脱位型颈脊髓损伤患者再次手术治疗的原因,总结经验教训。方法:对1993年1月～2003年2月间13例经再次手术治疗的无骨折脱位型颈脊髓损伤患者的临床资料进行回顾性分析,根据其影像学表现,分析致伤的病理基础与形成因素的特点。结果:患者再手术的原因主要有:(1)前次手术入路选择不当(8例);(2)前次手术中脊髓减压不彻底(5例)。再手术后均获随访(平均43个月),神经功能得到了一定的改善(JOA评分改善率平均为40.6%)。结论:手术入路选择不当和减压不彻底是无骨折脱位型颈脊髓损伤再手术的主要原因,再次手术治疗应针对此类损伤致伤特点,选择合理的手术入路,并矫正前次手术不当之处,可获得一定的疗效。     

Injuries in national karate competitions in Finland

The injuries sustained in 6 national karate competitions in Finland were studied by analyzing data from 450 bouts during the season 1991–1992. The analyzed data included a personal interview with each competitor and detailed information on the bouts and any injuries sustained. The overall probability of injury was 0.28 per bout. These injuries occurred to 16% of the 647 competitors. Occurrence of injury was greatest among adult men, which was pronounced in final bouts. Of all injuries diagnosed by the physicians for the competitions, more than 95% were localized to the head. The majority of these were minor injuries. Experienced competitors were more injury-prone than beginners. On the other hand, none of the background factors studied significantly affected the probability of injuring one's opponent. Most injuries and penalties, as well as full scores, were caused by direct punches to the head. From these findings it was concluded that a protective guard for the head together with modification of competition rules could significantly reduce injuries.     

Evaluation of Hemoperitoneum Using a Single- vs Multiple-view Ultrasonographic Examination

Objective: To compare the sensitivities, specificities, and accuracies between a single-view ultrasonography (US) technique and a multiple-view technique for identifying hemoperitoneum in multiple-trauma patients.
Methods: Data from a prior prospective study of US for trauma diagnosis at a level I trauma center were retrospectively analyzed. A convenience sample of adult patients (≥ 18 years of age) who had presented with major blunt or penetrating torso trauma and had undergone rapid trauma US examinations to detect hemoperitoneum were reviewed. The US interpretations by emergency physicians had been recorded prior to obtaining other diagnostic tests. Five views were evaluated, including the right intercostal oblique view examining Morison's pouch. Evidence of free intraperitoneal fluid by exploratory laparotomy, CT, or diagnostic peritoneal lavage (DPL) was used as the criterion standard.
Results: Of the 245 patients entered into the study, 37 had free intraperitoneal fluid, confirmed by CT, DPL, or exploratory laparotomy. With the multiple-view technique, US was 87% (95% CI = 71%, 96%) sensitive, 100% (95% CI = 97%, 100%) specific, and 98% (95% CI = 95%, 100%) accurate. The single-view technique, evaluating only Morison's pouch, was 51% (95% CI = 34%, 68%) sensitive, 100% (95% CI = 98%, 100%) specific, and 93% (95%. CI = 89%, 96%) accurate.
Conclusions: An initial trauma US examination using a multiple-view technique is more sensitive than that using a single-view technique for detecting hemoperitoneum in trauma patients.
