The aim of this study is to present our early clinical experience using the Unreamed AO Femoral Nail (UFN). The UFN system combines the advantages of numerous proximal interlocking options for the treatment of nearly all femoral fractures patterns with those of unreamed nailing (biological osteosynthesis, preservation of the cortical blood supply, closed mediate reduction, primary stability, high degree of patient comfort). Operation time and blood loss are reduced by eliminating the reaming procedure. The risk of infection is minimized by avoiding dead space. The positioning of the patient on the operating table without the use of traction allows for a minimally invasive surgical procedure. Our report deals with intraoperative handling, intra- and postoperative complications and the prospective clinical outcome in using the solid femoral nail system in Austria. Within nearly 2 years (August 1994-April 1996) 52 closed fractures and four second-degree open fractures were stabilized using the unreamed femoral nail. In 12 cases we used the spiral blade interlocking technique. Four times we changed from external fixation to the UFN. According to the AO classification, we found 8 fractures of the proximal femur (A 1/1: 1; A3/1: 2; A3/3: 5) and 48 diaphyseal fractures (A1:4; A2: 7; A3: 16; B1: 5; B2: 6; B3: 6; C1: 1; C2: 2; C3: 1). Thirty patients were followed up over an average period of 9.1 months postoperatively. The clinical and radiological results were excellent in 20 cases; average fracture healing time was about 10.6 weeks.
本研究的目的是介绍我们使用非扩髓AO股骨钉（UFN）的早期临床经验。UFN系统结合了多种近端锁定选择的优点，可用于治疗几乎所有类型的股骨骨折，同时还具备非扩髓髓内钉固定的优势（生物学接骨术、保留皮质血供、闭合间接复位、初始稳定性、患者舒适度高）。省去扩髓步骤可减少手术时间和失血量。避免死腔可将感染风险降至最低。患者无需牵引即可在手术台上定位，从而实现微创手术。我们的报告涉及在奥地利使用实心股骨钉系统的术中操作、术中和术后并发症以及前瞻性临床结果。在近2年（1994年8月至1996年4月）内，使用非扩髓股骨钉固定了52例闭合性骨折和4例二度开放性骨折。12例采用了螺旋刀片锁定技术。4次从外固定转换为UFN。根据AO分类，我们发现8例股骨近端骨折（A 1/1: 1例；A3/1: 2例；A3/3: 5例）和48例骨干骨折（A1:4例；A2: 7例；A3: 16例；B1: 5例；B2: 6例；B3: 6例；C1: 1例；C2: 2例；C3: 1例）。30例患者术后平均随访9.1个月。20例患者的临床和影像学结果极佳；平均骨折愈合时间约为10.6周。
