Optimal Patterns for Suturing

A mathematical model for computing stresses in sutured human skin wounds is presented. The model uses the incremental law of elasticity and elastic constants valid for in vivo orthotropic skin. The model is applied to compute the principal stress and displacements resulting from suturing small elliptical and circular wounds in a large at sheet of skin, in order to determine the optimal suturing...

Turning Pink Slips into Red Tape: The Unintended Effects of Employment Protection Legislation

This paper presents evidence on the link between employment protection legislation (EPL), such as mandated severance packages for fired workers, and the rate of unemployment in a cross-country panel data set of OECD countries from 1990-2013. We use both a traditional fixed effects panel specification with lags of the policy variable, and also a unique structural panel vector autoregression (PVA...

Suturing for surgical success.

The paramount goal of soft tissue surgery is closure of wound flaps, in the absence of tension on the flaps, which will lead to optimal wound healing. Surgical procedures that require flap manipulation such as those used with traditional periodontal therapy, periodontal plastic cosmetic surgery, hard and soft tissue regeneration, and the excision of pathologic tissue require excellence in execu...

Endoscopic Navigation for Minimally Invasive Suturing

Manipulating small objects such as needles, screws or plates inside the human body during minimally invasive surgery can be very difficult for less experienced surgeons due to the loss of 3D depth perception. Classical navigation techniques are often incapable of providing support in such situations, as the augmentation of the scene with the necessary artificial markers--if possible at all--is ...
