Median and Ulnar Nerve Injuries in Children and Adolescents- Long-term outcome and Cerebral reorganisation
A peripheral nerve injury may lead to serious disability and influence the individual´s quality of life. It is considered that children can regain better sensory and motor function after a peripheral nerve injury, but the exact mechanism behind such superior recovery is not known. The aim of the …

The Rat as a Translational Model of Neurotrauma: Primary Somatosensory Input and Imaging Biomarker Validation Following Spinal Cord and Peripheral Nerve Injuries
… used models of spinal cord (SCI) and peripheral nerve (PNI) injuries because their anatomy and physiology approximates that of humans, while their size and management make them economical and practical for large scale studies. Although the CNS does not regenerate, the peripheral nervous system …

Regeneration of Peripheral Nerves Using Neuroinductive Biomaterial Scaffolds
Over 18 million extremity injuries are recorded in the United States each year, resulting in a substantial number of peripheral nerve injuries that account for more than $150 billion in health care costs. Clinically, treatment consists of direct surgical repair, implantation of a nerve guidance …

Development of tissue engineering strategies for supporting regeneration after injuries of the nervous system
… structures for supporting regeneration after nerve injuries. Injuries of the nervous system can have serious consequences such as the loss of motoric and sensoric function. As existing treatment methods for the peripheral nervous system include several unsatisfying deficits and due to the …

Modification of the schenck classification of knee dislocations based on a global consensus study
Objectives: Knee dislocations (KD) are complex injuries defined as incongruity of the tibiofemoral joint which leads to tears of two or more of the main stabilizing knee ligaments, and they are often associated with damage to surrounding soft tissue or neurovascular structures. A classification …

Peripheral nerve regeneration through collagen devices with different in vivo degradation characteristics
… people are treated each year for peripheral nerve injuries that require surgery. Functional recovery of motor and sensory capability is limited following autograft, the most common procedure for peripheral nerve repair. Tubulation repair of a transected peripheral nerve presents an …

Biomedical and Psychosocial Factors Associated with Pain and Disability after Peripheral Nerve Injury
… in patients following traumatic upper extremity nerve injuries. This was approached by conducting 3 studies. The first study surveyed peripheral nerve surgeons regarding the assessment of pain in patients with nerve injury. The results showed that only 52% of surgeons always evaluate pain in …

Investigation of bench methods for determining stiffness of solid ankle-foot orthoses
… caused by stroke and spinal cord or peripheral nerve injuries. The biomechanical functions of plastic AFOs are determined by their thickness, the material selection and their geometry. The geometry, also known as trim-line, reflects the stiffness in relationship to the range of motion that the …

Digital Fibers: Materials, Processing, and Information
… porous fibers, enabling a means for accelerated nerve regeneration for patients with nerve injuries. Finally, I describe the fabrication of fibers with digital capabilities, including memory storage and analog-to-digital sensing. These polymeric fibers contain an engineered material setup that …

Dysphagia and recurrent laryngeal nerve injury in anterior cervical discectomy and fusion
… contribute to dysphagia and recurrent laryngeal nerve palsy complications following ACDF surgery. Objective: 1. To determine the rates of dysphagia and recurrent laryngeal nerve complications following ACDF reported in the literature and potential associated factors. 2. To determine rates of …

Effects of Electrical Stimulation and Testosterone in Translational Models of Peripheral Nerve Injury
<p>As functional recovery following peripheral nerve injury is dependent upon successful regeneration and target reconnection, combinatorial treatments that enhance different regeneration events may be required for recovery from severe injuries. The neurotherapeutic effects of electrical …

Biohybrid Peripheral Neural Interfaces: Combining Cell Transplantation and Flexible Electronics for Functional Neurological Restoration
Peripheral nerve injuries result in a disconnection in the nervous system communication and a consequent loss in neurological function. Currently, there is very limited treatment for these conditions. Neuroprosthetics and cell transplantation are promising approaches to restore lost neurological …

Paediatric and Adolescent civilian gunshot injuries: a 10 year epidemiological study
… showed a decrease in paediatric civilian gunshot injuries following the introduction of the 2004 Firearms Control Act. This study examines the epidemiological trends of gunshot injuries in children from January 2011 to December 2020. Methods: A descriptive cross-sectional study was performed on …

Investigating the Impact of Biochemical and Mechanical Stimuli on Motor Neuron Growth
Peripheral nerve injuries are one of the most prevelant trauma injuries, and the current golden standard for treatment is an autologous nerve graft. The use of tissue engineered nerve grafts has increased in recent years, a neural scaffold, cellular or acellular, is utilized to promote nerve …

Peripheral nerve regeneration through tubular devices : a comparison of assays of device effectiveness
Peripheral nerve injury affects nearly 200,000 patients annually in the United States and unless treated results in paralysis of skeletal muscle and loss of sensation. Previous studies in this laboratory have focused on comparing the effectiveness of various tubular devices in repairing …

Deposition of Electroactive Polymers onto Polymer Nanofibers for Nerve Regeneration
Although peripheral nerves can regenerate after an injury through the Wallerian degeneration process, the degree of regeneration is often not efficient enough to achieve full return of functionality. To overcome the disadvantages of current nerve repair approaches, peripheral nerve tissue …

Design and evaluation of neuroregenerative properties of 4D hydrogel scaffolds
… target due to its relevance in peripheral nerve repair, and to its connection to the non-regenerative central nervous system (CNS). Severe peripheral nerve injuries have a limited regenerative capacity, with interventions typically not leading to full functional recovery. Ways to improve …

Towards depth-resolved multi-cubic-centimeter field of view endoscopic camera for intraoperative nerve identification.
One out of every five peripheral nerve injuries in the United States has an iatrogenic origin. These injuries can cause chronic neuropathies, paresthesia, and varying functional losses. To reduce the risk of nerve injury, surgeons meticulously identify and track nerves within the surgical field …

Plasticity of the pain control system induced by neuropathic pain: the amygdala-medulla system
… and spontaneous pain. The maintenance of these nerve injury-induced symptoms depends on abnormal discharge from peripheral nerves and pronociceptive changes in spinal and supraspinal mechanisms mediating and modulating pain-related signals. The aims of this work were: first, to elucidate what is …
