to assess the small-scale 3D printing feasibility and cost estimation of a device for controlled dynamization. ⋯ 3D printing of the controlled dynamization device is feasible and its cost seems affordable to most healthcare services, which could optimize the consolidation of diaphyseal fractures and reduce treatment time for patients.

Optimal treatment of patients with rib fractures requires identification of those patients at risk of pulmonary complications. It is also important to determine which patients would benefit from Surgical Stabilisation of Rib Fractures (SSRF). This study aims to validate two scoring systems (RibScore and SCARF score) in predicting complications and association with SSRF in an Australian trauma population. Clinical observation suggests that complications and criteria for SSRF is associated with anatomical and physiological factors. Therefore it is hypothesized that utilisation of an anatomical (RibScore) and physiological (SCARF) in conjunction will have improved predictive ability. ⋯ Retrospective Cohort Study LEVEL OF EVIDENCE: Level III.

As a two-stage surgical procedure, Masquelet's technique has been used to care for critical-size bone defects (CSD). We aimed to determine the effects of modified and altered bone cement with biological or chemical enriching agents on the progression of Masquelet's induced membrane (IM) applied to a rat femur CSD model, and to compare the histopathological, biochemical, and immunohistochemical findings of these cements to enhance IM capacity. ⋯ The modified PMMA with E and BC, and CPC as an alternative spacer resulted in a well-differentiated IM and increased IM progression by elevating BALP and OC levels in serum and by mediating expressions of TGF-β and VEGF at the tissue level. Estrogen-supplemented cement spacer has yielded promising findings between modified and alternative bone cement.
