The immunodiffusion and complement fixation tests for histoplasmosis were compared on 2,090 initial sera from 70 proven cases of histoplasmosis, 177 routine chest hospital patients, and 1,843 coal miners from outside the major endemic area for histoplasmosis. The complement fixation test using histoplasmin as antigen detected antibodies in the sera of 72.8% of the 70 proven cases, while the com...

Introduction : Closed reduction is widely accepted as the initial management of subaxial facet dislocation. However, there a substantial risk neurological deterioration due to herniated discs or fractured vertebral bodies during procedure. Recently, it has been reported that open and fixation via an anterior approach for dislocation had good outcomes. some cases with locked facets were difficul...

OBJECTIVE Posttraumatic amnesia is superior to the initial Glasgow Coma Scale score for predicting traumatic brain injury recovery, but it takes days/weeks to assess. Here, we examined whether return of visual fixation-a potential marker of higher cognitive function-within 24 hours of ICU admission could be used as an early predictor of traumatic brain injury recovery. DESIGN Two-phase cohort...

PURPOSE Tacks and sutures ensure a strong fixation of meshes, but they can be associated with pain and discomfort. Less invasive methods are now available. Three fixation modalities were compared: the ProGrip™ laparoscopic self-fixating mesh; the fibrin glue Tisseel™ with Bard™ Soft Mesh; and the SorbaFix™ absorbable fixation system with Bard™ Soft Mesh. MATERIALS AND METHODS Meshes (6 cm ×6 ...

Preservation of the soft tissue is of particular importance in the care of pilon fractures. Improper soft tissue management has been attributed to high rates of nonunion, nerve injury, and failures (1–12). Traditional open reduction internal fixation (ORIF) of pilon fractures allows for direct visualization of the fracture(s) but is criticized for the large exposure and periosteal stripping. As...

BACKGROUND Despite increasing attention on fixation of a soft tissue anterior cruciate ligament graft in the tibia, there have been no studies on the use of a bone dowel as a joint line fixation device for promoting fixation properties, especially stiffness at the time of implantation. PURPOSE To determine whether compacting a bone dowel into the tibial tunnel improves fixation stiffness, yie...

In the paper, an issue of CMM measurement strategy sleeves and pins designed for wear tests in cycloidal drive. The was proposed, based on initial out-of-roundness scanning mode. Proposed approach ensured that pin measured along its entire 40 mm length with only small area fixation ca. 5 left out, all probing points cylindricity deviation assessment were collected one fixation. It demonstrated ...

Tibial pilon fractures result from high-energy trauma unlike usual ankle fractures. Their management provides numerous challenges to the orthopaedic surgeon including obtaining anatomic reduction of articular surface and the management of associated soft tissue injuries. This article aims to review major advances and principles that guide our practice today. We also discuss a treatment algorith...

The tissue-suture interface is the most vulnerable and challenging part of adequate restoration and fixation in rotator cuff repair. We describe a simple stitch technique for arthroscopic rotator cuff repair using knotless suture anchors based on the cow hitch. The simple cow hitch stitch technique is easy to perform, especially under difficult conditions, and provides excellent initial fixatio...

Primates actively examine the visual world by rapidly shifting gaze (fixation) over the elements in a scene. Despite this fact, we typically study vision by presenting stimuli with gaze held constant. To better understand the dynamics of natural vision, we examined how the onset of visual fixation affects ongoing neuronal activity in the absence of visual stimulation. We used multiunit activity...
