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

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
