Example: OrthoSorb®• Pins perform similar to metallic fixation for

protection against shear and rotational forces, while eliminating most of its disadvantages. A gradual rate of absorption allows for an optimal transfer of support to the bone as it heals. OrthoSorb® pins are made of poly-p-dioxanone (PDS), an alternative to metal fixation for selected applications

Absorbable polymers are used to make pins,screws, and rods for orthopedic applications

Dynamic Compression Plate

Bolt Nut Washers

Used for:– fixation of fractures of the proximal or distal end of long

bones– condylar fractures of the femur– fusion of a joint– surgical procedures that involve cutting a bone• Companies:– Pioneer Surgical Technology, Synthes, Arthrex, Smith &Nephew, Zimmer Holdings, Acumed, Conmed, Johnson &Johnson• 39 approved products from 9 different companies

Use of shape memory alloy in closing the jaw bone:Before applying heat; After applying heat

Memory™ Staple

Achieve optimum compression for fusions and osteotomies– Delivered in its frozen state– The nitinol temperature-sensitive memory metalstructure reacts to the ambient temperature as well as the temperature of the patient when it is inserted– The oval strap section opens and the arms close,drawing the bone fragments or joint together in acontrolled and predictable process• Companies:– Smith & Nephew, Medtronic, Johnson & Johnson, Stryker, Biomet, Wright Medical Technology, Arthrex, Covidien, Orthofix, Acumed

External Fixation SystemUsed for– open and closed long bone fracture fixation to includetensioned wire fixation of– Periarticular fractures– Arthrodesis– Limb lengthening– Osteotomy– Reconstruction– Pseudoarthrosis– Correction of bony or soft tissue defects and deformities

Hoffman (Ilizarov and Taylor) externallong-bone fracture fixation device

External Fixation (Tempfix®)used for the treatment ofperiarticular fractures ofthe lower extremity• The frame is made withunique, lightweight,radiolucent material– patient comfort withmultiple degrees of freedom– enables x-ray and MRIviewing of the fracture
