  Journal of Head Neck & Spine Surgery Juniper Publishers Author by:  Kartik Sonawane Abstract Spine surgery is associated with multiple postoperative complications, ranging from simple nausea and vomiting to devastating complications leading to postoperative morbidity or mortality. The postoperative neurological impairment, especially in the neurologically intact patient, is a dreadful event that makes it difficult for the surgeon to perform technically challenging or high-risk spine surgeries. Preoperative or intraoperative factors that can influence the postoperative neurological status include nature and the severity of the pathology, comorbid conditions of the patient, preexisting neurological symptoms, multiple levels involved, complex surgery or instrumentation, surgical blood loss, neurological monitoring, hemodynamic parameters, polypharmacy, and total duration of the surgery. In addition to several known contributing factors (fixation failure, epidural hematoma, ...

  Journal of Head Neck & Spine Surgery Juniper Publishers Author By:  Vinay Kumar Tiwari Abstract Introduction:  Barbed sutures have the potential advantage of decreased operative time and better wound cosmesis due to bidirectional fixation of wound. Present study evaluates the complications and scar cosmesis after skin closure with barbed sutures. Material and Methods:  This was a prospective, observational study. Patients underwent subcuticular skin suturing in surgically created clean wounds. Half of the wound closure was done with barbed absorbable suture and other half with non-barbed absorbable sutures. Comparison of scar cosmesis and wound complications was done. Results:  Mean time taken for suturing per cm of wound was lower in barbed suture group. Suture extrusion rate was higher in barbed suture group. No statistically significant difference was found between cosmesis of scar and rates of infection between the two groups. Conclusion:  The cur...

  Journal of Head Neck & Spine Surgery Juniper Publishers Author by:  C Bastien Abstract Traumatic Brain Injuries (TBI) have been a major cause of morbidity and mortality for many years. The Organ Trauma Model (OTM) is a state of the art computer model, available to scientific community, which can calculate the threat to the life via white and grey matter brain injury severity level based on Peak Virtual Power (PVP), founded on the 2nd law of thermodynamics. The OTM model has however assumed, based on previous literature, that bridging veins rupture when the grey matter maximum principal strain exceeds 25.5%. This assumption does not permit to locate the vein tear as well as quantify the blood loss, which defines the injury severity. A 10-pair bridging vein shell computer model was devised, using published material properties and geometrical data connecting the grey matter to the dura, and defined a maximum principal strain to rupture of 15%. This bridging vein model was t...
