Recently studies have aimed at developing transcutaneous spinal direct current stimulation (tsDCS) as a non-invasive technique to modulate spinal function in humans. Independent studies evaluating its after-effects on nociceptive or non-nociceptive somatosensory responses have reported comparable effects suggesting that tsDCS impairs axonal conduction of both the spino-thalamic and the medial lemniscus tracts. The present study aimed to better understand how tsDCS affects, in humans, the spinal transmission of nociceptive and non-nociceptive somatosensory inputs...

BACKGROUND: Anastomosis in gastrointestinal (GI) surgery is a commonly performed procedure. Irrelevant various methods of intestinal anastomosis were followed - recent advance is the use of a stapler as a device for GI anastomosis. Due to the use of staplers, technical failures are a rarity, anastomosis is more consistent and can be used at difficult locations. MATERIALS AND METHODS: : Between 2008 and August 2016, 75 patients with esophagus or gastroesophageal junction carcinoma underwent curative intent resection either via a right posterolateral thoracotomy (TTE) or transhiatal esophagectomy or video-assisted thoracoscopic surgery with linear stapler anastomosis...

BACKGROUND AND OBJECTIVE: Cervical spinal cord stimulation (cSCS) is a safe and effective treatment for chronic axial neck pain and upper limb neuropathic pain. We report our novel institutional experience with performing cSCS trials with patients placed in an upright sitting position. This allows easy access to the cervical epidural space and has the added benefit of unobstructed access to the airway. METHODS: We retrospectively reviewed data for patients who had undergone cervical spinal cord stimulation trial procedures in an upright, sitting position at the Vanderbilt University Medical Center...

The aim of this study was to evaluate the efficacy and feasibility of a life-size 3-dimensional printing assisted posterior internal fixation. We performed a retrospective review of 138 patients who received posterior atlantoaxial internal fixation from October 2009 to March 2015 with a minimum follow-up period of 12 months. Group A included 76 patients who received the conventional free-hand technique. Group B included 62 patients who were treated with internal fixation assisted by 3D printing. The placement accuracy of the screw was evaluated in the computed tomography images according to the methods of Hojo and clinical outcomes were evaluated using the visual analogue scale, the Japanese Orthopedic Association Score, and the Neck Disability Index score...

Facial paralysis can be a devastating consequence resulting from blunt and penetrating trauma to the head and neck, as well as surgical injury, either accidental or due to involvement by tumor. In addition, the etiology can be attributed to a variety of other causes, ranging from infectious to metabolic, and is frequently idiopathic in nature. The incidence of facial nerve injury during temporomandibular joint (TMJ) surgeries varies among surgeons. There are many factors that could contribute to the injury of the temporal and zygomatic branches of the facial nerve...

INTRODUCTION: Hirayama disease is a rare cervical myelopathy predominantly affecting young adults and mainly found in Asia. It results in a pure motor distal lesion of the upper limbs with slow progression. Dynamic magnetic resonance imaging (MRI), which allows the diagnosis to be made, shows a typical appearance of anterior compression of the cervical spinal cord associated with enlargement of the posterior epidural spaces due to a dilated venous plexus. Surgery is considered when conservative treatment has failed...

The thoracic spine presents a challenge for biomechanical testing. With more segments than the lumbar and cervical regions and the integration with the rib cage, experimental approaches to evaluate the mechanical behavior of cadaveric thoracic spines have varied widely. Some researchers are now including the rib cage intact during testing, and some are incorporating follower load techniques in the thoracic spine. Both of these approaches aim to more closely model physiological conditions. To date, no studies have examined the impact of the rib cage on thoracic spine motion and stiffness in conjunction with follower loads...

BACKGROUND: The incidence of metachronous esophageal squamous cell cancer (ESCC) after head and neck cancer (HNC) and in elderly patients has increased. Both elderly ESCC patients and ESCC patients after HNC surgery are at potential risk for dysphagia, and for the latter, surgery in the neck is difficult. An intrathoracic anastomosis that bypasses the cervical procedure is preferable to preserve swallowing function and reduce surgical risk. In gastrectomized patients, because the stomach cannot be used as a substitute, securing graft blood supply is critical, but microvascular anastomosis cannot be easily added in procedures for intrathoracic posterior mediastinal reconstruction...

PURPOSE: Motor nerve transfer surgery involves re-innervation of important distal muscles using either an expendable motor branch or a fascicle from an adjacent functioning nerve. This technique is established as part of the reconstructive algorithm for traumatic brachial plexus injuries. The reproducible outcomes of motor nerve transfer surgery have resulted in exploration of the application of this technique to other paralysing conditions. The objective of this study is to report feasibility and increase awareness about nerve transfer as a method of improving upper limb function in patients with cervical motor radiculopathy of different aetiology...
