three cases who underwent surgery in different areas of the craniofacial region were reported with bradycardia developing intraoperatively during flap traction. many cases of the oculocardiac reflex during treatment of the orbital region have been reported in the literature. this manuscript recorded that reflex bradycardia can occur during traction or stretching of any structure innervated by t...

This article presents Navier type closed-form solutions for static bending, elastic buckling and free vibration analysis of symmetric functionally graded (FG) sandwich beams using a hyperbolic shear deformation theory. The beam has FG skins and isotropic core. Material properties of FG skins are varied through the thickness according to the power law distribution. The present theory accounts fo...

background prostate traction is one way to control post-prostatectomy bleeding. the most popular method involves traction with a catheter fixed to the thigh with adhesive bands. however, this method has its own drawbacks. objectives we aimed to simplify this traction procedure and to overcome its disadvantages. patients and methods from 2007 - 2015, a new method was used to control post-prostat...

Focal adhesions (FAs) are integrin-based transmembrane assemblies that connect a cell to its extracellular matrix (ECM). They are mechanosensors through which cells exert actin cytoskeleton-mediated traction forces to sense the ECM stiffness. Interestingly, FAs themselves are dynamic structures that adapt their growth in response to mechanical force. It is unclear how the cell manages the plast...

We present a 58-year-old right-handed man, who consulted us with an 11-year history of Dupuytren's disease. To correct contracture of the little finger, we performed regional fasciectomy, skin grafting, and distraction arthrolysis of the proximal interphalangeal (PIP) joint using an external fixator. Preoperative or postoperative skeletal traction has been advocated to treat potential or residu...

In this paper we consider a viscoelastic string whose deformation is controlled at one end. We study the relations and the controllability of the couples traction/velocity and traction/deformation and we show that the first couple behaves very like as in the purely elastic case, while new phenomena appears when studying the couple of the traction and the deformation. Namely, while traction and ...

TECHNIQUE After drain insertion, a horizontal mattress suture is placed. A simple knot is placed distally half way along the two free ends. The two threads are wrapped tightly together the same way around the tube up to the level of the knot. The free ends of the knot are then passed proximally under the loop of the skin suture (Fig 1). The suture is pulled fi rmly, and the free ends are separa...

Neurofibromatosis type 1 (NF-1) is one of the most common autosomal dominant disorders affecting humans. Patients with NF-1 may present with characteristic orthopaedic manifestations such as scoliosis, congenital pseudoarthrosis and limb hyperttrophy. Dislocation of the hip associated with NF-1 is a rare occurrence. There is a relative paucity of reported cases of pathological hip dislocation i...

Traumatic hip dislocation in children is relatively rare accounting for about 5% of all hip dislocations. Most of the hip dislocations seen in children are of the posterior type but the much rarer anterior and anterior-inferior (obturator) types have also been described. We present the case of an eight years old girl with an obturator type of hip dislocation following trivial trauma. She was tr...

Near total amputation of the upper limb if unsalvageable would cause severe disability. However, delayed revascularisation can be life threatening. We report two cases of revascularisation of the upper limb following near total amputation that was successful and functional after a warm ischaemic time of ten hours. The first was a traction avulsion injury of the arm leaving major nerves contused...
