Adult trauma patients with autism spectrum disorder (ASD) may have distinct care needs that have not been previously described. We hypothesized that due to differences in clinical care and disposition issues, injured adults with ASD would have increased lengths of stay, higher mortality, and increased rates of complications compared to adults without ASD. ⋯ This statewide analysis suggests injured patients with ASD have increased lengths of stay without other clinical or outcome differences. Given significant differences in discharge destination, these findings support early involvement of a multidisciplinary care collaborative. Further research is needed to identify factors that contribute to disparities in care for adults with ASD.

Polytrauma patients are at risk for fracture nonunion, but the reasons are poorly understood. Increased base deficit (BD) is associated with hypovolemic shock. Although shock delays bone healing in animal models, there have been no clinical studies evaluating the impact of BD on nonunion risk. ⋯ A BD ≥ 6 within 24 h of admission was associated with a significantly increased risk of developing lower extremity fracture nonunion in polytrauma patients, even after adjusting for multiple other risk factors. Acute post-traumatic acidosis may have effects on long-term fracture healing.

Periprosthetic fractures (PPF) following total knee (TKA) and hip arthroplasty (THA) have become more common over the years. The aim of the present study was to assess morbidity and mortality following surgery for PPF of hip and knee. ⋯ Postoperative morbidity caused by implant-related complications is higher in younger patients and those receiving ORIF. With the statistical approach used, potential underestimation of actual complication rates may have been avoided, taking into account death as the competing event. Despite being based on a retrospective, heterogenous patient collective treated at a level-1 trauma centre, our results indicate that careful planning of the surgical procedure beyond 2 days, taking into consideration both patient's age and activity level, has no negative effect on patient outcome.

To establish the finite element model of T12 and L2 (T12-L2) pedicle screw fixation for severe L1 burst fracture, and quantitatively simulate and analyze the screw stress and vertebral displacement in different degrees of L1 posterior upper wall fracture (PUWF), and evaluate whether PUWF degree is a risk factor for fixation failure. ⋯ The posterior upper wall fracture of vertebral body (VB) of type A burst fracture is not an independent risk factor for the failure of short-segment pedicle screw fixation (SSPSF). Anterior flexion of type A fractures combined with severe PUWF of VB was a risk factor for the failure of SSPSF.

The aim of this study was to assess the feasibility of 3D printing a customised implant at the point of care from a manufacturing and logistics perspective. We hypothesised that customised plate production would be possible within a clinically relevant time frame of 72 hours using currently available technology. ⋯ Production of patient-specific 3D printed plates for fixation of proximal tibia fractures at the point of care is achievable within a clinically acceptable time frame provided adequate manufacturing facilities and skilled manpower are in place.
