Surgical treatment of complex tibial plateau fractures by closed reduction and external fixation. A review of 32 consecutive cases operated

Abstract Complex tibial plateau fractures are a challenge in trauma surgery. In these fractures it is necessary to anatomically reduce the articular part of the fracture and to obtain stable fixation. The aim of this study is to review the results of a surgical technique consisting of fluoroscopic closed reduction and combined percutaneous internal and external fixation. Thirty-two complex tibial plateau fractures in 32 patients were included. Twenty-one fractures were closed, 4 were open Gustilo grade I, 3 were Gustilo grade II and 4 were Gustilo grade III. The mean age was 37.8 years (range 21–64 years). Surgery was performed with patients in transcalcaneal traction and the knee flexed at 30° was used. Through a 1-cm incision centred over the tibial metaphysis of the tibia, a 3.2-mm hole was drilled in the antero-medial tibial aspect. The tibial plateau fracture fragments were elevated using either 1 or 2 curved Kirschner wires under fluoroscopy to control the reduction. Then the fragments were fixed with 2 cannulated AO screws inserted through small incisions into the medial aspect of the tibial plateau. Knee rehabilitation started postoperatively. Weight bearing started after 8–12 weeks depending upon the radiographic appearance. All external fixators were removed in outpatient facilities. All patients were clinically and radiographically evaluated at a mean follow-up of 48 months (range 38–57 months). Clinical results were evaluated according to the Knee Society clinical score. Average healing time was 24 weeks (range 18–29 weeks). In 1 patient a non-union occurred. This patient was treated with open reduction and plate fixation. In 2 patients a varus knee deformity occurred and a surgical correction was performed. There were no surgical complications. Mean knee range of motion was 105° (range 75–125°) and mean Knee Society clinical score was 89. Twenty-five results were scored as excellent, 4 good, 2 fair and 1 poor. Using this technique there is limited soft tissue damage and virtually no periosteum damage to the fracture fragments. However anatomical reconstruction of the joint can be obtained. Furthermore knee rehabilitation can be started immediately after surgery. We think that these factors were responsible for the optimal clinical long-term results.     

术中超声导航辅助切除脑动静脉畸形

目的探讨术中实时超声导航在脑动静脉畸形(AVM)外科治疗中的应用价值。方法26例脑AVM显微手术切除术中,使用Aloka SSD 4000型超声检查仪扫描,进行AVM定位、辨别供血动脉和引流静脉;确定血肿与AVM的关系以及血流动力学监测。病变切除后重复超声检查AVM残留与否,并与术后脑血管造影结果对比。结果26例畸形血管团均住实时超声下清晰显示并获得全切除。血肿区为高同声无血流信号;供血动脉与正常血管在血流动力学上有差别;术中超声影像所示的病变全切除为术后血管造影所证实。结论术中实时超声能够对脑AVM进行准确定位,指导皮质切口的设计,并可判定病灶是否全切除.对于术前的MRI、DSA检查起到很有价值的补充作用。     

永磁速愈贴对妇产科手术切口愈合的观察

目的探讨永磁速愈贴对切13的消肿止痛，促进伤口愈合和防止疤痕粘连与普通敷料进行对比观察。方法将住院行妇产科手术100例患者与同期住院的手术患者进行对比观察。结果永磁速愈贴切13愈合佳者84．0％，良好者13．0％，愈合差为3．0％，而普通敷料为28．0％、60．0％和12．0％，p〈0．01（x^2=63．660）。结论永磁速愈贴切口具有透气、保湿、促进伤口愈合、消肿、止痒，防止疤痕形成等作用。而普通敷料透气性差，保湿性差，术后切口有红肿、缝线反应、切口愈合时间长及切口局部愈合后有痛痒感。     

Surgical treatment of multiple knee ligament injuries in 44 patients: 2–8 years follow-up results

The purpose of the study was to evaluate the mid-term results of surgical treatment in different groups of patients with multiple knee ligament injuries. Review of our patients’ records revealed that 48 acute and chronic patients were surgically treated for combined knee injury. Due to severe capsular damage in these injuries, open techniques were used. In our treatment protocol, avulsed ligaments and tears of the posterolateral and posteromedial corner were repaired if possible, whereas midsubstance tears of cruciate ligaments and chronic cases were reconstructed with autografts. Postoperatively, an accelerated program of rehabilitation was introduced, aiming to progressively mobilize the joint and improve muscle endurance. For the follow-up evaluation we designed a protocol composed of two parts. In the first part, anatomical lesions were recorded and in the second part, clinical evaluation was performed using the Lysholm score, the Tegner rating system, the IKDC evaluation form, and the KT1000. Student’s t tests and chi-square tests were used for data analysis. Forty-eight patients (mean age 28.6±11.9 years; 41 males) were classified according to the specific anatomical structures involved. Group A included 12 anterior cruciate ligament (ACL) and medial structure injuries, group B included 11 ACL or posterior cruciate ligament (PCL) ruptures combined with posterolateral injuries, and group C consisted of 25 knee dislocations (ACL and PCL ruptures which might be combined with damage of the collateral ligaments). Thirty-eight patients were surgically treated during the acute phase and ten patients were treated chronically. Forty-four patients (91.6%) were followed up at a mean of 51.3±29.9 months. Average Lysholm score was 87±12.3; average Tegner score was 5.09±2.19 before accident and 4.34±2.12 in re-examination; IKDC score was A in 10 cases, B in 22, C in 6, and D in 6. The mean range of motion was 129.9°±12.5°. The average loss of extension and flexion were 1.6°±2.5° and 7.6°±7.9°, respectively. The side-to-side difference in corrected anterior and posterior translation in quadriceps neutral angle and in anterior translation in 30° angle was <3 mm for about 65% of our patients. Surgical treatment of multiple knee ligament injuries, using autografts, provided satisfactory stability, range of motion, and subjective functional results. However, despite the improvement of the quality of life, the preinjury patients’ activity level was not fully obtained in re-examination. Patients underwent surgical treatment during the acute phase had better scores in several points, but finally there was no statistical significance between acute and chronic patients. Moreover, no statistically significant differences were observed among the groups with specific damaged anatomical structures.     

输尿管口囊肿的微创手术治疗

目的评价输尿管口囊肿的微创手术治疗方法及其疗效。方法回顾性分析25例行经尿道电切（TURU）手术治疗输尿管口囊肿患者资料。男9例，女16例；年龄18—61岁，平均38岁；单侧18例，双侧7例；单纯输尿管囊肿22例，异位输尿管囊肿3例。结果25例患者手术一次成功22例，手术平均时间15min，术后平均住院3d。术后定期B超、膀胱造影随诊，随诊时间1—9年，3例异位输尿管囊肿合并重复肾、输尿管畸形患者存在术后膀胱输尿管返流，2例再次行开放手术后痊愈。结论TURU是治疗成人输尿管口囊肿的有效方法；当合并存在重复肾输尿管畸形或术后膀胱输尿管返流时，应采用输尿管膀胱抗返流手术。

改良(足母)趾腓侧皮瓣修复拇手指指腹缺损

目的介绍改良躅趾腓侧皮瓣修复拇、手指指腹缺损的手术方法。方法对15例拇、手指指腹缺损的患者，采用改良的躅趾腓侧皮瓣移植修复。该皮瓣在传统躅趾腓侧皮瓣设计方法基础上，将皮瓣腓侧缘及近端分别向背侧及趾蹼侧移动，从而避开口径细小又紧贴于皮下的躅趾腓侧浅静脉，直接游离第一跖背浅静脉；皮瓣的动脉和神经游离仍以常规方式进行。结果术后15例皮瓣全部成活，未发生动、静脉危象。12例获得4～11个月随访，3例失访。手功能评定：优10例，良2例。皮瓣两点分辨觉为4～8mm，12例对皮瓣外形满意。供区行走无影响，步态正常。10例对供区外观满意，2例欠满意，其中1例蹲趾腓侧偶有触痛。结论应用改良躅趾腓侧皮瓣可显著降低手术难度，提高成功率。

颈椎病伴椎管狭窄患者再手术问题探讨

目的：探讨颈椎病伴椎管狭窄患者再手术的原因、手术方式及其相关问题。方法：我院2002年7月～2003年12月对40例颈椎病伴椎管狭窄术后疗效不佳或症状复发的患者进行了后路多节段（5个或以上）减压手术。根据其手术治疗方式及影像学资料分析再手术原因，并进行术后疗效评价。结果：经前路手术者再手术的主要原因为：（1）伴有多节段颈椎管狭窄因素时，只选择部分压迫重的节段行减压融合15例；（2）经前路多节段（≥3个节段）减压融合后，相邻节段继续退变，出现新的脊髓压迫表现及椎间不稳定9例；（3）伴有OPLL时，行部分节段前路减压融合后，病变呈进展表现，产生或加重对脊髓的压迫8例。经后路手术者再手术的原因为：（1）后路减压节段不够5例（包括1例前后路联合手术者）；（2）后路减压不充分3例。再手术后随访1．3～2．7年，平均2．1年，所有患者脊髓功能获得一定的提高，JOA评分改善率为51．3％。结论：颈椎病伴椎管狭窄病例再手术的主要原因为椎管狭窄因素仍然存在，经后路多节段（5个或以上）减压手术治疗可彻底去除颈椎管狭窄因素，有效解除脊髓前、后方所受的压迫，可获得较满意的临床疗效。
