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,

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 metal
structure 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 a
controlled and predictable process
• Companies:
– Smith & Nephew, Medtronic, Johnson & Johnson,
Stryker, Biomet, Wright Medical Technology,
Arthrex, Covidien, Orthofix, Acumed
External Fixation System
Used for
– open and closed long bone fracture fixation to include
tensioned wire fixation of
– Periarticular fractures
– Arthrodesis
– Limb lengthening
– Osteotomy
– Reconstruction
– Pseudoarthrosis
– Correction of bony or soft tissue defects and deformities
Hoffman (Ilizarov and Taylor) external
long-bone fracture fixation device
External Fixation (Tempfix®)
used for the treatment of
periarticular fractures of
the lower extremity
• The frame is made with
unique, lightweight,
radiolucent material
– patient comfort with
multiple degrees of freedom
– enables x-ray and MRI
viewing of the fracture
