Study, design and prototyping of arm splint with additive manufacturing process
The aim1 of this study is to propose the additive manufactured 3D printed technique for adaptive organic design splint as a solution for the problems generated by the use of casts in medical applications. Since the end of the XVIII century, when casts begin to be used, they have barely improved. Thanks to new manufacture and material techniques, we can improve and modernize this commonly used fracture treatment method. Based on three dimensional digitalization techniques and modeling via reverse engineering software, a 3D printed splint is proposed, which will provide the benefits of cast avoiding its deficiencies.
Evaluating Iatrogenic Complications of the Total-Contact Cast: An 8-Year Retrospective Review at Cleveland Clinic.
BACKGROUND
Total-contact casting is an effective method to treat various pathologic abnormalities in patients with diabetic neuropathy, but its use is frequently associated with iatrogenic complications.


METHODS
The largest retrospective review to date of iatrogenic complications of total-contact casts was conducted over an 8-year period at Cleveland Clinic.


RESULTS
In the past 8 years, 23% of patients developed complications, and the most common complication was a new heel ulcer formation. Of these complications, 92.1% resolved, 6.4% were lost to follow-up, and 1.4% resulted in a partial foot amputation. Mean cast duration was 10.3 days for patients who developed a total-contact cast iatrogenic complication. The most common indication for the use of a total-contact cast was a neuropathic foot ulceration.


CONCLUSIONS
The results of this study support the use of total-contact casting in the insensate patient with diabetes. However, adequate staff training in total-contact cast application is recommended to reduce complications.
Self‐Determination, Wellbeing, and Threats of Harm
David Rodin argues that the right of national-defence as conceived in international law cannot be grounded in the end of defending the lives of individuals. Firstly, having this end is not necessary because there is a right of defence against an invasion that threatens no lives. However, in this context we are to understand that ‘defending lives’ includes defending against certain non-lethal threats. I will argue that threats to national-self determination and self-government are significant non-lethal threats to the wellbeing of individuals that can justify lethal defensive force. Therefore the end of defending individuals can ground a right of national-defence against a ‘bloodless invasion’. Secondly, Rodin argues that defending lives is not a sufficient condition for military action to be national self-defence, because humanitarian intervention is military action to defend individuals, and such action is in deep tension with national self-defence. I will argue that a reductive account, grounded in claims of need and threats of harm, can justify principles of both intervention and non-intervention on the same grounds; that is, protecting the wellbeing of individuals.
