Results of operative treatment using radical thoracoplasty in 31 patients with funnel breast were analyzed. Mean age of patients was 14.98±4.36 years. All patients had concomitant spine deformity. For purpose of cosmetic effect improvement the mini-invasive submammary accesses were used. Fixatives of sternocostal complex from nickel-titanium with shape-memory were worked out. The shape memory effect was achieved by cooling of the implant that resulted in implant plasticity. After being inserted the implant restored its original shape. That technique allowed achieving full correction of the deformity and positive cosmetic effect in all patients. No complications associated with plate migration were revealed. Radical thoracoplasty with thoracocostal complex stabilization by plate with shape-memory effect is pathogenetically justified and allows correcting the funnel chest of any degree and form and is indicated to patients of any age groups.

Abstract The shape memory effect and the superelasticity of nickel titanium (NiTi) alloys are beneficial for design of compliant mechanisms. The superelastic behavior of NiTi can be tailored for optimal flexure design in the compliant mechanism, allowing large deformation and shape change. The shape memory effect can also be utilized to actuate the compliant mechanism flexures enabling programing of the material to take on variety of shapes at different temperatures over time. The compliant mechanism analyzed in this work is inspired from 3D multi leg spider-like locomotion, enabling movement in all directions by triggering different target shapes in time. The control of the material spatial distribution facilitated by additive manufacturing will enable tailored superelastic and shape memory behavior in the flexures of the multifunctional 3D compliant mechanism. Design optimization and analyses as well as overall shape change are explored in this work. Superelastic joints are introduced as flexures to enable segment flexibility. The temperature change is used for actuation taking in consideration different initial strain conditions.
