Disease relevance of External Fixators

• Fifteen pediatric femoral fractures in 14 patients were treated with external fixation using the EBI Orthofix unilateral external fixator [1].
• Repair was staged by firstly removing all implants, secondly treating the osteomyelitis with appropriate antibiotics while spanning the cortical-deficient fracture site with a Kirschner external fixator, and finally rigid fixation of the fracture with incorporation of an ethylene oxide-sterilised intercalary cortical allo-implant [2].
• The Colles Fracture Plate (Biomet, Inc, Warsaw, Indiana) can be used to treat any comminuted Colles fracture for which an external fixator is considered proper management [3].
• We carried out a clinical study to verify the potential of this protein in fresh tibial closed fractures, using OP-1 associated with osteosynthesis by means of a monolateral external fixator [4].

High impact information on External Fixators

• METHODS: Forty consecutive elderly female patients who had a pertrochanteric fracture were randomized to be treated with either fixation with a 135 degrees four-hole sliding hip screw (Group A) or an external fixation device with hydroxyapatite-coated pins (Group B) [5].
• Control subjects, who had not received a Norian SRS injection, underwent closed reduction and application of a cast or external fixator for six to eight weeks [6].
• We systemically administered alendronate to rats fitted with external fixators [7].
• RESULTS: The Ilizarov with carbon fiber rings, Richards Hex-Fix, and Large Synthes External Fixator had <1 kg of magnetic attraction at all three locations [8].
• RESULTS: The administration of TGF-beta1 did not alter callus size, mechanical properties, or the distribution of tissues in the callus of fractures that were stabilized in locked external fixators [9].

Anatomical context of External Fixators

• METHODS: Mice tail discs between the ninth and 10th caudal vertebrae were compressed in vivo for 7 days with static axial loads using external fixators [10].

Associations of External Fixators with chemical compounds

• Antimicrobial efficacy of external fixator pins coated with a lipid stabilized hydroxyapatite/chlorhexidine complex to prevent pin tract infection in a goat model [11].
• The normal motion of the cricoarytenoid joint was characterized and analyzed in this study using seven fresh cadaver larynges mounted rigidly in an external fixator apparatus after radiopaque markers were attached to laryngeal landmarks [12].
• In the HCO group, the RSA measurements were performed at the time of removal of the external fixator, 1 month later and 1 year after surgery [13].
• This external fixator had titanium fiducials wedged into the fixator carbon tubes serving as landmarks for paired-point registration [14].
• The use of methylmethacrylate as an external fixator in children and adolescents [15].

Gene context of External Fixators

• Mechanical performance of external fixators with wires for the treatment of bone fractures--Part II: Wire tension and slippage [16].
• Four calcanei, which were massively destroyed as a result of blasting injuries from land mines, and 18 severely comminuted calcaneal fractures with bony defects (in one patient, both feet), also from land mines, were treated using a circular external fixator for reconstruction by osteogenic distraction [17].
• Examples of such implants include the DCS/DHS implant system, the self-tapping screw, the cannulated screw, and the pinless external fixator [18].
• The method is demonstrated with the Orthofix DAF unilateral external fixator, for which a mathematical stiffness matrix is defined using experimental measurements in six degrees of freedom [19].
• Static and fatigue tests of the standard Orthofix unilateral external fixator (Orthofix SRL, Verona, Italy) were performed [20].

Analytical, diagnostic and therapeutic context of External Fixators

• In a 1-cm rabbit diaphyseal segmental defect stabilized with an external fixator, tricalcium phosphate was compared to intact autograft, crushed autograft, and open defects [21].
