ABSTRACT The study aimed to estimate excess mortality in patients aged 60 years or older up 1 year after pelvic fracture compared with a population without fracture. In this retrospective population-based observational study, we use routine data from large health insurance Germany. For each patient first between 2008 and 2010 (n = 5685 cases, 82% female, mean age 80 ± 9 years), about 34 individuals 193,159 controls) were frequency matched by sex, at index date, month. We estimated survival...
Abstract Besides the use of autologous bone grafting several osteoconductive and osteoinductive methods have been reported to improve healing. However, persistent non‐union occurs in a considerable number cases compromised angiogenesis is suspected impede regeneration. Hyperbaric oxygen therapy (HBO) improves angiogenesis. This study evaluates effects HBO on defects treated with defect model rabbits. Twenty‐four New‐Zealand White Rabbits were subjected unilateral critical sized diaphyseal...
Abstract The release of “neutrophil extracellular traps” (NETs) has been identified as a novel immune response in innate immunity. NETs are composed neutrophil‐derived circulating free DNA (cf‐DNA) and neutrophil cytoplasm‐derived proteins such proteases. In this study, we analyzed the putative diagnostic value synovial cf‐DNA/NETs for identification septic arthritis. Forty‐two patients with joint effusion who had undergone arthrocentesis were included. From fluid, (j‐cf‐DNA) levels directly...
The management of knee osteoarthritis includes the use wedged shoe insoles to unload affected compartment. Although biomechanical effects on joint are known and described, only little is about their influence pelvis spine. Therefore, purpose this study was evaluate different foot positions, such as how they could be achieved by insoles, pelvic position spinal posture.A total 51 test subjects were measured for study. positions (inner outer margin increase, positive negative heel height)...
This biomechanical study is the first to compare 3 fixation methods—bilateral fixed-angle plate, modified anterior tension wiring, and cannulated lag screws with wiring—in multifragmentary distal patella fractures. A T-shaped 3-part fracture simulating a articular (AO/OTA 34-C2.2) was created in 18 human cadaver knee specimens. Three groups were using homogenous ages bone mineral densities based on method received. Repetitive testing over 100 cycles performed by moving against gravity from...
Background All available treatment options for osteochondral and chondral defects do not restore hyaline cartilage are limited to decreasing associated pain, maintaining or improving joint function. The purpose of this study was evaluate the potential erythropoietin (EPO) in combination with bone marrow aspiration concentrate (BMAC) mini-pigs. Methods 14 Goettinger mini-pigs, which a 6×10 mm defect medial femoral condyle both knee joints created, were randomized into four groups: biphasic...
Abstract Total knee arthroplasty (TKA) is a very successful procedure. The alignment in TKA has been identified as being of importance to prevent early implant failure and patient dissatisfaction. Our hypothesis was that patients with preoperative varus deformation remaining slight their natural after will have superior clinical results compared who are restored neutral alignment. A total 115 were corrected from (varus–neutral) 33 kept (varus). Standardized postoperative full-length...
Intramedullary nailing has become the gold standard to treat femoral shaft fractures. It is unknown which technique orthopedic surgeons prefer. The goal of this study was determine current techniques and perioperative complications intramedullary diaphyseal Fifty-one institutions in 26 countries participated an international survey assess detailed descriptions preferred operative strategies complications. Altogether, 517 cases fractures were collected. Internet-based incorporated information...
Arthroscopic suture fixation of tibial eminence fractures using FiberWire is a favorable therapeutic option. The application biodegradable material may be advantage especially during childhood. aim this study was to evaluate the biomechanical properties materials PDS II and Vicryl compared with FiberWire.Bone mineral density evaluated by pqCT in 18 human knee specimens 3 similar groups were formed. A standardized anterior fracture created performed each (PDS II, Vicryl, FiberWire) 6...
Background: Thromboelastometry like ROTEM® is a point-of-care method used to assess the coagulation status of patients in rapid manner being particularly useful critical care settings, such as trauma, where quick and accurate assessment can guide timely appropriate treatment. Currently, this not yet comprehensively available with sparse data on its effectiveness resuscitation rooms. The aim study was effect early thromboelastometry probability mass transfusions mortality severely injured...
The objective of this study comparing the proximal femoral nails Targon PF (Aesculap, Tuttlingen, Germany) and Proximal Femoral Nail Antirotation (PFNA; Synthes. Oberdorf, Switzerland) was to observe complications postoperative results following pertrochanteric fracture fixation, with special attention devoted dynamic properties both implants under physiological load in vivo. survey designed as a randomized, prospective 80 patients who had sustained (AO type 31.A2). Postoperative...
While morphologic magnetic resonance imaging (MRI) is the modality of choice for evaluation ligamentous wrist injuries, it merely static and incapable diagnosing dynamic instability. Based on real-time MRI algorithm-based image post-processing in terms convolutional neural networks (CNNs), this study aims to develop validate an automatic technique quantify movement. A total 56 bilateral wrists (28 healthy volunteers) were imaged during continuous alternating maximum ulnar radial abduction....
