A new anterior intrapelvic approach for the surgical management of displaced acetabular fractures involving predominantly column and quadrilateral plate is described. In order to establish five ‘windows’ instrumentation, extraperitoneal space entered along lateral border rectus abdominis muscle. This so-called ‘Pararectus’ approach. The feasibility safe dissection optimal instrumentation pelvis was assessed in cadavers (ten hemipelves) before implementation a series 20 patients with mean age...

Early prediction of massive transfusion (MT) is critical in the management severely injured trauma patients. Variables available early after injury including physiologic, laboratory, and rotation thromboelastometric (ROTEM) parameters were evaluated as predictors for need MT.After Institutional Review Board approval, we retrospectively reviewed a cohort patients (Injury Severity Score ≥ 16) admitted to Level I center with ROTEM measurements on hospital admission during 1-year study period....

Acetabular fractures still are among the most challenging to treat because of complex anatomy, involved surgical access fracture sites and relatively low incidence these lesions. Proper evaluation planning is necessary achieve anatomic reduction articular surface stable fixation pelvic ring. The goal this study was test feasibility preoperative in acetabular using a new prototype tool based on an interactive virtual reality-style environment.7 patients (5 male 2 female; median age 53 y (25...

Notochordal cells (NC) remain in the focus of research for regenerative therapy degenerated intervertebral disc (IVD) due to their progenitor status. Recent findings suggested action on more mature cells, presumably by secretion specific factors, which has been described as notochordal cell conditioned medium (NCCM). The aim this study was determine NC culture conditions (2D/3D, fetal calf serum, oxygen level) that lead significant IVD activation an indirect co-culture system under normoxia...

This study evaluated critical thresholds for fresh frozen plasma (FFP) and platelet (PLT) to packed red blood cell (PRBC) ratios determined the impact of high FFP:PRBC PLT:PRBC on outcomes in patients requiring massive transfusion (MT).Retrospective review a cohort massively transfused blunt trauma admitted Level I center. MT was defined as ≥10 units PRBC within 24 hours admission. Critical associated with mortality were identified using Cox regression time-dependent variables. Impacts...

To present two new approaches to acetabular surgery that were established in Berne, and which aim at enhanced visualization anatomical reconstruction of fractures.The trochanteric flip osteotomy allows for surgical hip dislocation, was introduced as a posterior approach fracture management involving the column wall. For fractures predominantly anterior quadrilateral plate, Pararectus is described.Full exposure joint, provided by osteotomy, facilitates reduction or femoral head safe...

The modified Stoppa approach is performed for safe and efficient management of acetabular fractures involving the anterior column. This avoids dissection inguinal canal, femoral nerve, external iliac vessels as seen in "second window" ilioinguinal has thus been shown to be less invasive than approach1. As an intrapelvic approach, it facilitates medial displacement fracture patterns quadrilateral plate dome impaction that typically occur elderly2,3. reduced morbidity this particular relevance...

Objectives: To compare the free-hand (FH) technique of placing interlocking screws to a commercially available electromagnetic (EM) targeting system in terms operating time, radiation dose, and accuracy screw placement. Methods: Between September 2011 July 2012, we prospectively randomized 100 consecutive femur shaft fractures 99 patients requiring intramedullary nails either FH using fluoroscopy (n = 43) or EM 38; Sureshot). Setting: Single Level 1 University Hospital Trauma Center. Main...

Traumatic posterior dislocation of the hip associated with a fracture acetabular wall and neck femur is rare injury. A 29-year-old man presented at level 1 trauma centre locked right hip, fractures femoral acetabulum after bicycle accident. An attempted closed reduction had failed. This case report describes in detail surgical management clinical radiological outcome. Open fixation preservation intact retinaculum was undertaken within five hours injury trochanteric osteotomy. Two years...

Abstract The inner surface layer of human joints, the synovium, is a source stem cells for repair articular cartilage defects. We investigated potential normal synovium to form novel and compared its chondrogenic capacity with that two patient groups suffering from major joint diseases: young adults femoro-acetabular impingement syndromes hip (FAI), elderly individuals osteoarthritic degeneration knee (OA). Synovial membrane explants these three were induced in vitro undergo chondrogenesis...

Acetabular fractures involving predominantly the anterior column associated with a disruption of quadrilateral surface can be treated instrumentation implementing stabilization surface. The recently introduced suprapectineal buttress plate is specifically designed to prevent secondary medial subluxation femoral head, especially in elderly patients reduced ability for partial weight bearing. Whereas there are guidelines available safe screw fixation and posterior columns, might concern...

Purpose Despite different existing methods, monitoring of free muscle transfer is still challenging. In the current study we evaluated our clinical setting regarding such tissues, using a recent microcirculation‐imaging camera (EasyLDI) as an additional tool for detection perfusion incompetency. Patients and methods This was performed on seven patients with soft tissue defect, who underwent reconstruction gracilis muscle. Beside standard protocol (clinical assessment, temperature strips,...
