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.

目的:探讨国产股骨近端髓内钉（proximalfemoralnail,PFN）,在老年股骨转子周围骨折治疗中的应用、疗效及并发症。方法:总结自2002年3月-2004年5月使用国产PFN治疗56例股骨转子周围骨折（男25例,女31例;年龄62⁸4岁,平均70.2岁）。手术使用骨科牵引床,在C形臂X线机下行闭合复位、锁定技术。随访观察骨折愈合情况、颈干角变化,以关节功能、疼痛情况、是否畸形等制订随访标准。结果:56例中随访49例,平均随访时间6.5个月。全部病例骨折均愈合,1例术后感染,2例出现颈螺钉切割股骨头（其中1例出现明显的外旋短缩畸形）。关节功能恢复良好,优37例,良9例,可2例,差1例,优良率为93.8%。结论:国产PFN内固定具有损伤小、固定牢固、生物力学优点突出等特点,是治疗老年股骨转子周围骨折的有效方法之一。     

后外侧融合对胸腰椎爆裂型骨折疗效的影响

目的 观察后外侧融合对预防胸腰椎爆裂型骨折短节段固定失败的作用及意义。方法 本组60例胸腰椎爆裂型骨折患者，A组30例均为我院收治患者，B组30例均为外院手术来我院复查的患者。A组行短节段内固定自体髂骨植骨、后外侧融合术；B组仅行短节段内固定，未植骨融合。平均随访16个月，在X线侧位片上测量Cobb角、伤椎后凸角及矢状面指数（SI），临床疗效评价采用下腰痛评分法（low back outcome score，LBOS）。结果 手术前、后两组间Cobb角、伤椎后凸角、SI比较，差异无统计学意义（P〉0．05），而末次随访时两组间Cobb角、伤椎后凸角、SI比较，差异有统计学意义（P〈0．01）。LBOS评分A组的优良率为73％（22／30），B组仅为43％（13／30）。结论 后外侧融合是降低内固定失败、减少纠正丢失等并发症的有效措施，只行内固定而不做植骨融合明显增高了并发症的发生率，是不恰当的手术方式。

人工肱骨头置换术治疗高龄复杂肱骨近端骨折

目的探讨和分析采用人工肱骨头置换术治疗复杂肱骨近端骨折的适应证、手术技术要点和早期疗效。方法对12例肱骨近端四部分骨折伴肱骨头脱位的高龄患者,早期手术行人工肱骨头置换。手术采用三角肌胸肌间入路,先复位大小结节,确定假体高度,骨水泥固定假体保持30°左右的后倾,大小结节再复位固定,必要时取骨折的肱骨头自体骨植骨,术后早期功能锻炼。结果术后平均随访16．6个月,术后未发生感染、神经损伤、关节脱位和假体周围骨折。采用Neer评分系统评定人工关节功能,平均为84．4分,90分以上(优)3例,80～89分(满意)7例,70～79分(不满意)2例,满意率为83．3%。12例患者疼痛方面平均得分为33．5分,功能方面为25．6分,运动方面为16．5分,解剖重建方面为8．8分。结论在正确选择手术适应证、掌握手术技术以及合理的术后康复等前提下,人工肱骨头置换术是治疗高龄患者复杂肱骨近端骨折的有效方法,尤其在减轻创伤后肩关节疼痛方面效果最为显著。但在恢复肩关节活动度方面仍欠满意,需加强对患者术后关节康复训练的指导工作。
