“…5 Fixation using an LCP is an effective treatment method in terms of union rate, pain and functional outcomes. 6,7 In a prospective multi-center study on 144 patients with 169 fractures fixed with LCP was reported by Sommer et al in 2003. 45 were humeral and 19 radial fractures.…”

“…Biomechanical characteristics of long-bone fracture stabilisation with internal fixators have been described in human orthopaedics for the locking compression plate (LCP) (4,11). Similar information is not available for the Unilock system, as it is not used for fracture treatment of long bones in humans.…”

“…The findings of biomechanical studies have led to the formulation of application principles for use of internal fixators in osteosynthesis of long-bone fractures in humans (4,11). Some of these application principles may be transferred to veterinary orthopaedics.…”

“…This study showed that the relative motion between the plate and bone was significant, as the zero friction model was 65% more flexible than the directly coupled model. Mathematical/ numerical models have also been used to evaluate the fibre-reinforced resorbable plates for long-bone fixation (35)(36)(37)(38)(39)(40). It is likely that these non-metallic materials will play an important role in the future development of internal fixation techniques.…”

The compressive stress shielding at the fractureinterface immediately after fracture-fixation delays callus formation and bone healing. Likewise, the tensile stress shielding in the layer of bone underneath the plate can cause osteoporosis and decrease in tensile strength of this layer.In this study a novel forearm internal fracture fixation plate made from short carbon fibre reinforced plastic (CFRP) was used in an attempt to address the problem. Accordingly, it has been possible to analyse the stress distribution in the composite plates using finite-element modelling.A three-dimensional, quarter-symmetric finite element model was generated for the plate system. The stress state in the underlying bone was examined for several loading conditions. Based on the analytical results the composite plate system is likely to reduce stress-shielding effects at the fracture site when subjected to bending and torsional loads. The design of the plate was further optimised by reducing the width around the innermost holes.
