BACKGROUND: Fishtail deformity is a rare deformity of the humerus exhibiting concavity of the lateral trochlea, resulting in ulnotrochlear joint derangement. We wanted to share our experience that osteochondritis dissecans of the capitellum is a common associated complication. OBJECTIVE: To summarize imaging of fishtail deformity in children centered on complications of the radiocapitellar joint. MATERIALS AND METHODS: From the radiology information system, we identified all patients <18 years with the diagnosis of fishtail deformity...

Recent studies suggest region-specific metabolic activity in hamstring muscles during injury prevention exercises, but the neural representation of this phenomenon is unknown. The aim of this study was to examine whether regional differences are evident in the activity of biceps femoris long head (BFlh) and semitendinosus (ST) muscles during two common injury prevention exercises. Twelve male participants without a history of hamstring injury performed the Nordic hamstring exercise (NHE) and stiff-leg deadlift (SDL) while BFlh and ST activity were recorded with high-density electromyography (HD-EMG)...

Objective: Among pediatric injury, brain injury is a leading cause of death and disability. To improve outcomes, many developed countries built neurotrauma databank (NTDB) system but there was not established nationwide coverage NTDB until 2009 and there have been few studies on pediatric traumatic head injury (THI) patients in Korea. Therefore, we analyzed epidemiology and outcome from the big data of pediatric THI. Methods: We collected data on pediatric patients from 23 university hospitals including 9 regional trauma centers from 2010 to 2014 and analyzed their clinical factors (sex, age, initial Glasgow coma scale, cause and mechanism of head injury, presence of surgery)...

BACKGROUND: Diffuse axonal injury (DAI) on MRI has been associated with poor functional outcome after moderate-severe traumatic brain injury (msTBI). Yet, DAI assessment with highly-sensitive MRI-techniques is unfeasible in the acute trauma setting, and CT remains the key diagnostic modality despite its lower sensitivity. We sought to determine whether CT-defined-hemorrhagic-DAI (hDAI) is associated with discharge and favorable 3-and 12-month functional outcome (Glasgow Outcome Score ≥4) after msTBI...

Traumatic brain injury (TBI) results in systemic changes in coagulation and inflammation that contribute to post-traumatic morbidity and mortality. The potential interaction of platelets and pro-inflammatory cytokines in the modulation of coagulation, microthrombosis, and venous thromboembolic events after moderate TBI (TBI) has not been determined. Using a murine model, we hypothesized 1) that the degree of platelet-induced coagulation varies depending on the platelet aggregation agonist 2) platelet-induced coagulation changes in a time-dependent manner following TBI, and 3) changes in platelet-induced coagulation are mirrored by changes in the levels of circulating pro-inflammatory cytokines...

OBJECTIVES: We reported on a patient with mild traumatic brain injury (TBI) who showed recovery of an injured cingulum concurrent with improvement of short-term memory, which was demonstrated on follow-up diffusion tensor tractography (DTT). METHODS: A 55-year-old male patient suffered head trauma resulting from falling from approximately 2 m while working at a construction site. The patient showed mild memory impairment (especially short-term memory impairment) at 3 months after onset: Memory Assessment Scale (global memory: 95 (37%ile), short-term memory: 75 (5%ile), verbal memory: 80 (9%ile) and visual memory: 112 (79%ile))...

Post-concussion syndrome (PCS) is often caused by an uncomplicated mild head injury but followed by long-lasting somatic, cognitive and psychiatric symptoms. For many years PCS has been an area of controversy between clinicians. New diagnostic techniques and clinical researches has shed light to some neurobiological aspects behind PCS. In Diagnostic and Statistical Manual of Mental Disorders V PCS is redefined as a neuro-cognitive condition emphasizing the importance of neuropsychological deficits among these patients...

A man in his late thirties was found in a supine position in the hallway of his house. He had been diagnosed with epilepsy at approximately 20 years old. Since stopping treatment, epileptic events occurred more frequently and his condition deteriorated in the past 2 years. Autopsy revealed that head injuries were found on the left side of his head. A fracture from the left parietal bone to the anterior cranial fossa was also detected. A subdural hemorrhage (hematoma) spanned a wide range. A subarachnoid hemorrhage was also identified in the left parietal region...

Background: The most widely used methods of describing traumatic brain injury (TBI) are the Glasgow Coma Scale (GCS) and the Abbreviated Injury Scale (AIS). Recent evidence suggests that presenting GCS in older patients may be higher than that in younger patients for an equivalent anatomical severity of TBI. This study aimed to assess these observations with a propensity-score matching approach using the data from Trauma Registry System in a Level I trauma center. Methods: We included all adult patients (aged ≥20 years old) with moderate to severe TBI from 1 January 2009 to 31 December 2016...

Brit Long, Alex Koyfman
Neurotrauma is a leading cause of death and is associated with many secondary injuries. A balance of mean arterial pressure (MAP) and intracranial pressure (ICP) is required to ensure adequate cerebral blood flow and cerebral perfusion pressure. Evaluation and management in the emergency department entails initial stabilization and resuscitation while assessing neurologic status. ICP management follows a tiered approach. Intubation requires consideration of preoxygenation, head of bed elevation, first pass success, and adequate analgesia and sedation...

Concussion is a brain injury induced by biomechanical forces that is broadly defined as a complex pathophysiological process affecting the brain. The intricate link between biomechanical input and concussion injury response is poorly understood. We aimed to test the hypothesis that greater biomechanical forces would result in the presentation of more concussion-related symptoms that would take longer to resolve. The objective of this study was to investigate the relationship between an array of biomechanical parameters measured for concussive impacts and the presentation and resolution of concussion symptoms...

PURPOSE: Questionnaires investigating semiology and comorbidities of psychogenic non-epileptic seizures (PNES) have been used mainly to help physicians expedite referrals to epilepsy centres for confirmation of diagnosis rather than as alternative diagnostic tool when video-EEG monitoring (VEM), the current gold standard, is not available or is inconclusive. METHODS: We developed one structured questionnaire for patients, exploring subjective experiences and vulnerabilities and one for eyewitnesses, focused on features observable during typical events to study prospectively 50 consecutive adult patients with PNES or epileptic seizures (ES) admitted for VEM...

Hip dislocation is an important orthopedic emergency usually seen in young patients who have experienced high-energy trauma, often resulting in significant long-term morbidity. Rapid identification and reduction is critical, as prolonged dislocation increases the risk of developing avascular necrosis of the femoral head, and posttraumatic osteoarthritis is a common complication, even in the absence of associated fractures. Identification and timely management of hip dislocation are highly dependent on imaging, both at presentation and after attempted reduction...

REVIEW
Michael R Hamblin
There is a notable lack of therapeutic alternatives for what is fast becoming a global epidemic of traumatic brain injury (TBI). Photobiomodulation (PBM) employs red or near-infrared (NIR) light (600-1100nm) to stimulate healing, protect tissue from dying, increase mitochondrial function, improve blood flow, and tissue oxygenation. PBM can also act to reduce swelling, increase antioxidants, decrease inflammation, protect against apoptosis, and modulate microglial activation state. All these mechanisms of action strongly suggest that PBM delivered to the head should be beneficial in cases of both acute and chronic TBI...

OBJECT: facing mild traumatic brain injury (mTBI) clinicians must decide whether to perform a CT scan to detect a potential intracranial hemorrhage.Many useful guidelines have been developed for general population, but there is no general consensus about the best practice to adopt when dealing with patients on antiplatelet or anticoagulation drugs. The relatively recent introduction of new anticoagulants and second generation antiplatelet drugs poses new challenges in this field. There is no data in the literature about the relative risk of intracranial bleeding in such categories...

OBJECTIVES: Head injury (HI) induces a hypercatabolic state, dysimmunity, and septic complications that increase morbidity and mortality. Although compromised immune function is usually incriminated in infection occurrence, gut dysbiosis could also be involved in this phenomenon and, to our knowledge, has never been considered. To assess if HI could affect microbiota, we explored the impact of HI on intestinal microbiota in a rodent model of fluid percussion. METHODS: Nineteen rats were randomly assigned to two groups: Healthy rats fed ad libitum (n = 7) and HI rats (n = 12), which received standard enteral nutrition for 4 d...

Monteggia fractures are rare traumatic injuries in cats and dogs. Ulna repair is mostly achieved by plates. Stable radial head fixation however is challenging. Temporary position screws have to be removed due to rotation forces in the elbow joint causing screw loosening. We present a novel and simple method using a sling technique, which holds the radial head in its physiological position and allows normal elbow movement.
