Purpose: Our aim was to elaborate how on and off signals contribute to pattern ERGs and pattern visual evoked potentials (VEPs) by using pedestal patterns arising from incremental and decremental onset stimulation. Methods: Pattern onset/offset ERGs and VEPs were produced by black and white checks of 60' side length and 88% spatial contrast appearing in a 16° field for 200 ms from white (110 cd/m2), black (7 cd/m2), and gray (48 cd/m2) backgrounds and disappeared for 1000 ms...

INTRODUCTION: The most common surgical treatment of traumatic spine fractures is through a posterior approach using pedicle screws and rods. Postoperative treatment protocols including the use of postoperative orthoses however differ between hospitals and surgeons. A three-point hyperextension orthosis is designed to support proper posture and unload the anterior column. Some motion remains when wearing an orthosis, and its main value in postoperative treatment is therefore believed to be pain relief and patient confidence...

Bipolar segmental clavicle fractures are simultaneous clavicle fractures of both proximal and distal ends. Few case reports describing these fractures have been published, and the management of these injuries have remained controversial. Non-operative treatment is likely to result in poor shoulder function due to the instability of the fracture in patients with high physical demands. In contrast, surgical treatment with fixation of both proximal and distal ends of the clavicle possibly may cause life-threatening complications...

Introduction: The original Harris hip score (HHS) does not contain ability to perform squatting and sitting cross legged as items in the questionnaire and hence a need was felt to modify the Harris hip score so that it could stay relevant in functional assessment of Indian patients in the rural setting. Validity, responsiveness and ceiling floor effect of the Harris hip score after internal fixation of pertrochanteric fracture has not been previously described. The objective of the study was to investigate construct validity, responsiveness and ceiling floor effects of the modified Harris hip score (mHHS)...

Distal humerus fractures show increasing incidence with age. Due to preexisting osteoporosis, the surgeon is regularly confronted with complex comminuted intraarticular fractures. The maintenance of autonomy in daily life and avoidance of permanent care dependency is a dogma in the care of geriatric patients. Accordingly, a stable post-operative situation that allows early functional post-operative treatment is mandatory, especially in the elderly patient. Open reduction and stable internal fixation using double plate osteosynthesis are the current osteosynthetic standard of treatment...

Scapular fractures are rare injuries and usually occur due to high energy trauma. Displaced Intra articular fractures usually require operative treatment and yields better outcomes as compared to conservative management. To assess the functional and radiological outcomes of displaced intra-articular scapular fractures managed with open reduction and internal fixation. 12 patients were retrospectively reviewed and included in the study. Post-operative functional outcomes were assessed using mean quick DASH (Disability of arm, hand and shoulder) score while radiological outcomes were analyzed as percentage of implant cut-through, mal-union, non-union or infection...

The purpose is to identify risk factors of functional outcome following proximal humerus open reduction and internal fixation. Patients treated for proximal humerus fractures with open reduction and internal fixation were enrolled in a prospective data registry. Patients were evaluated for function using the Disability of the Arm, Shoulder and Hand score for 12 months and as available beyond 12 months. Univariate analyses were conducted to identify variables associated with functional outcome. Significant variables were included in a multivariate regression predicting functional outcome...

Deep-sea massive sulfide deposits remaining after ceasing of hydrothermal activity potentially provide energy for a chemosynthetic ecosystem in the dark, cold marine environments. Although yet-uncultivated bacteria in the phylum Nitrospirae and the class Deltaproteobacteria are known to dominate the microbial communities of sulfide deposits at and below the seafloor, their metabolic capabilities remain largely elusive. Here, we reveal the metabolic potential of these yet-uncultivated bacteria in hydrothermally inactive sulfide deposits collected at the Southern Mariana Trough by seafloor drilling...

BACKGROUND: Open reduction and internal fixation of Lisfranc injuries has typically used multiple longitudinal incisions or a single transverse incision to approach the tarso-metatarsal joint (TMTJ). The incidence of wound-related complications is considerable. We describe a novel single-incision approach that utilizes subcutaneous windows to the medial TMTJ. METHODS: A retrospective review identified 150 patients who underwent open reduction and internal fixation for Lisfranc injuries, via the modified dorsal approach, at our center between January 2011 and June 2016...
