A typical fibular fixator consisting of 8 crossed K wires and 4 rings with supporting struts was affixed to a fiberglass-filled epoxy bone fracture model. The ensemble was tested with an MTS servohydraulic testing machine in axial loading, bending (A-P, L-M), and torsion. Displacement transducers were placed on the frame and the bone to determine relative motion. The Ilizarov frame was relatively stiff in compression; failure occurred at about 100 kg due to slippage at the wire holders. In bending, it was much less rigid than the Hoffman-Vidal fixator due to bowing of the transverse wires and slippage of the bone along these wires. Stiffness is related to the wire-bone orientation: wires parallel or nearly parallel to the applied force provide little resistance to deformation. In torsion, the laxity in the system is due primarily to wire deflection or wide spacing between adjacent rings. Stiffness in compression and bending increased as a function of wire tension to about 130 kg (further tightness was not possible due to slippage at the wire holder). The Ilizarov fixator is less rigid than other fixators in all loading modes, particularly in axial compression. This may prove to be clinically beneficial as evidenced by increased osteosynthesis. However, the existing system has many sites of laxity. Care must be taken in frame construction to ensure adequate stability and necessary stiffness.","PeriodicalId":77501,"journal":{"name":"Bulletin of the Hospital for Joint Diseases Orthopaedic Institute","volume":"49 2 1","pages":"140-7"},"PeriodicalIF":0.0,"publicationDate":"1992-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/00003086-199207000-00003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"61385846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This implant works not only as a ligament but also as a scaffold onto which natural tissue grows from synovium. In an animal experiment, each strand of the L-K ligament was covered with new tissue by 2-3 weeks after anterior cruciate ligament reconstruction. Eight weeks postoperatively, abundant fibrous tissue with extensive vascularity covered the implant, which was still histologically immature. After 16 weeks, vascularization and tissue induction began to subside, and histologic analysis showed dense fibers running longitudinally and parallel. By 36 weeks, the new ligament looked like a natural anterior cruciate ligament, although histologically more cells could be seen than in the natural ligament. This maturation was observed only when the substitute was implanted under good tension. Clinically, the surgical procedure has been improved over the past 10 years, to the current practice in which the tape-in-tube double L-K ligament employs a small piece of autogenous tissue to promote early tissue induction and maturation. Using this practice (n = 135), more than 85% of the patients were satisfied subjectively, objectively, and arthroscopically at the 5-year postoperative FU period. Few patients had joint effusion postoperatively. Sacrifice of autogenous tissue is minimal. The patient can return to activities of daily living within 2 weeks, and more than 50% of them to sports within 10 weeks, and the new ligament is expected to keep its function for a long period as ingrowth completes the structure biologically.","PeriodicalId":77501,"journal":{"name":"Bulletin of the Hospital for Joint Diseases Orthopaedic Institute","volume":"51 2 1","pages":"140-54"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67612848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
