Six degrees of freedom (6DOF) refers to the freedom of movement of a rigid body in 3-dimensional space. Specifically, the object can move in 3 translations: up/down, left/right, and in/out, and in 3 rotations: pitch, yaw, and roll. In fracture care, the principle of 6DOF can be applied to each individual fracture fragment to help better understand fracture reduction and alignment. In the instance of a distal radius fracture, the 6DOF concept can be utilized to reduce the articular block in a systematic and controlled fashion...

We report the case of a 17-year-old male presented to the emergency department with a six weeks history of neck pain and no neurogical deficit. Computed tomography and magnetic resonance imaging revealed an expansile lesion in the axis, with soft tissue and spinal cavity invasion, without mielopathy signs. Tomography-guided mass biopsy was taken. Waiting for histopathologic results, the pacient developed acute tetraparesis and sphincter incompetence. Magnetic resonance revealed that the bone mass had grown with epidural compromise, mielopathy and new vertebral lesions...

OBJECTIVE: The polythetic system used by the Diagnostic and Statistical Manual for Mental Disorders (DSM-5) for diagnosing borderline personality disorders (BPD) is far from optimal; however, accumulated research and clinical data are strong enough to warrant ongoing utilization. This study examined diagnostic efficiency of the nine DSM-IV BPD criteria, then explored the feasibility of an optimized criteria set in classifying BPD. METHODS: Adults (N=1,623) completed the Structured Clinical Interviews for DSM-IV Axis II Disorders resulting in a BPD group (n=352) and an inpatient psychiatric control group (PC) with no personality disorders (n=1,271)...

BACKGROUND: Life-threatening arrhythmias (LTAs) can trigger sudden cardiac death or provoke implantable cardioverter-defibrillator (ICD) discharges that escalate morbidity and mortality. Longitudinal myofibrils predominate in the subendocardium, which is uniquely sensitive to arrhythmogenic triggers. In this study, we test the hypothesis that mitral annular systolic velocity (S'), a simple routinely obtained tissue Doppler index of LV long-axis systolic function, might predict lethal arrhythmias irrespective of left ventricular ejection fraction (LVEF)...

BACKGROUND: Kyphotic deformity occurrence after cervical laminoplasty is not rare. Several studies have emphasized the development of postoperative kyphotic deformity (PKD) will impair the functional outcome of cervical laminoplasty. We established and validated a nomogram prediction model for kyphotic deformity after laminoplasty in cervical spondylotic myelopathy patients (CSM) without preoperative kyphotic alignment. METHODS: Preoperative and 1-year postoperative data of 369 patients who underwent single-door cervical laminoplasty (SDCL) at the author's hospital between July 2010 and February 2018 were collected...

BACKGROUND: The development of a perfect method for determining the mean QRS axis (ÂQRS) is still lacking. HYPOTHESIS: We proposed a new simple method, whether this method is accurate is unknown. METHODS: The axis perpendicular to the mean QRS axis (P-ÂQRS) divides six limb leads into two groups. All the leads that are in the range of 180° along the ÂQRS are positive, while all the leads in another 180° are negative, one lead is isodiphasic if it is on the P-ÂQRS...
