#1
M Thomsen, P Thomas
Metal implants for osteosynthesis are nowadays standard in orthopedic and trauma surgery. Steel implants, especially cerclages, bands and wires, can show more corrosion due to friction and lead to encapsulation in connective tissue with fluid borders even without loosening. Corrosion and fluid borders are potentially more susceptible to incompatibility and infections. Titanium implants have the advantage of better allergic compatibility. Problems may occur in material removal, especially with titanium implants because material fractures occur more frequently...

BACKGROUND There is strong evidence that malocclusion and body posture are interdependent. The relationship between improvement of nasopharyngeal airway, correction of malocclusion by orthodontic treatment or orthognathic surgery, and changes in body posture were evaluated in several studies. The purpose of the present study was to analyze the effect of the orthodontic treatment with Twin-block appliance on body posture. MATERIAL AND METHODS The study group consisted of 23 children (mean age 12.45 (1.06) years)...

BACKGROUND: Fat embolism (FE) and the consequent FE syndrome occurring after trauma or surgery can lead to serious pulmonary injury, including ARDS and death. Current treatment of FE syndrome is limited to supportive therapy. We have shown in a rat model that the renin angiotensin system plays a significant role in the pathophysiology of FE because drugs interfering with the renin angiotensin system, captopril and losartan reduce the histopathologic pulmonary damage. The purpose of the current study was to determine if inhibition of renin by aliskiren, an FDA-approved drug for treating hypertension, would produce effective protection in the same model...

BACKGROUND: Pupillometry allows the measurement of pupillary diameter variations in response to nociceptive stimuli. This technique has been used to monitor the balance between analgesia and nociception. Under general anesthesia, the amplitude of pupillary dilation is related to the amount of administered opioids. The objective of this study was to determine whether at a constant infusion rate of opioids, the pupillary response was influenced by depth of hypnosis assessed by the bispectral index (BIS)...

Surgery of sepsis in trauma surgery and orthopedics is attracting increasingly more attention due to the rising presence of multidrug-resistant pathogens and the increasing number of operative interventions. Despite extensive experience over decades neither the symptoms nor the treatment strategies have been evaluated and it has become obvious that a scientific investigation of this complex topic is necessary for optimization of patient care under economically sound conditions. The aim of this article is to give a snapshot from German healthcare institutions for trauma surgery and orthopedics to answer some questions on this topic from the section for bone and soft tissue infections (SeKuWi) of the German Society for Orthopedics and Trauma (DGOU) in cooperation with the German Society for Hospital Hygiene (DGKH)...

Selenium is an essential trace element present in 25 selenoenzymes, playing critical roles in a variety of physiological processes, such as anti-oxidative defense and the modulation of cell proliferation and differentiation. This paper characterizes selenium-doped calcium phosphate coatings and evaluates their effects on the osteogenic activity, the proliferation of osteosarcoma cells and biofilm formation. To do so, the structure and elemental composition of the obtained coatings were analyzed, in addition to their thicknesses, and they were compared to pure calcium phosphate coatings...

INTRODUCTION: Ruptures of the Achilles tendon are the most common tendon injuries of the lower extremities. Besides the initial operative or non-operative treatment, rehabilitation of patients plays a crucial role for tendon healing and long-term outcome. As only limited evidence is available for optimized rehabilitation regimen and guidelines for the initial (e.g., first 6 weeks) rehabilitation are limited, this study investigated the current rehabilitation concepts after Achilles tendon rupture...

In this study we aimed to assess the in vivo osteoinductive properties of two composite scaffolds made of PLGA (poly-L-lactide-co-glycolide) and two types of gel-derived bioactive glasses, namely a high silica S2 bioactive glass (S2-PLGA composites) or high lime A2 bioactive glass (A2-PLGA composites). To achieve that, the potential of the composites to induce ectopic bone formation in a rabbit muscle has been examined along with the control PLGA scaffold. Cylinder-like scaffolds of 7  ×  3 mm (width  ×  height) were implanted into pouches created in the latissimus dorsi muscle of 18 New Zealand rabbits...

A 96-year-old woman developed hemiparesis 2 weeks after orthopedic surgery. Magnetic resonance imaging revealed multiple cerebral infarctions in the bilateral hemisphere. Transthoracic echocardiography revealed a mobile structure attached to the anterior mitral leaflet that protruded toward the left ventricular outflow tract. The structure was identified as an accessory mitral valve. Doppler echocardiography showed that there was no significant left ventricular outflow obstruction. This is a rare case of a silent accessory mitral valve that was detected after multiple cerebral infarctions...

ETHNOPHARMACOLOGICAL RELEVANCE: Following Venezuelan traditional medicine, females with heavy menstrual blood loss (menorrhagia) drink Brownea grandiceps Jacq. flowers (BG) decoctions to reduce the bleeding. In a previous study, we demonstrated that BG aqueous extract (E) possesses a potent anti-fibrinolytic activity capable of inhibiting plasmin, the main serine-protease that degrades fibrin. It is widely known that plasmin inhibitors are often used as anti-fibrinolytics to reduce bleeding during surgeries with high risk of blood loss such as cardiac, liver, vascular, tooth extraction and large orthopedic procedures, as well as for menorrhagia treatments...

BACKGROUND: Hip fractures are a major global health care issue, with the 1.26 million estimated cases in 1990 predicted to increase to 4.5 million by 2050. Varying models of care have been developed to improve outcomes following fragility hip fractures. Most of these care models embrace an interprofessional approach to care. Specialist orthopedic nurses play an important role in the management of fragility hip fracture patients and their contribution to the interprofessional health care team is an important predictor of patient outcomes...

BACKGROUND: Hospital readmission rates after surgery may represent an overall hospital effect or a combination of specialty and patient effects. We hypothesized that hospital readmission rates for procedures within specialties were more strongly correlated than rates across specialties within the same hospital. STUDY DESIGN: For general, orthopedic, and vascular specialties at Veterans Affairs hospitals during 2008-2014, 30-day risk-adjusted readmission rates were estimated for six high-volume procedures and each specialty...

BACKGROUND: It is unclear whether simultaneous surgery for posterior ankle impingement syndrome (PAIS) and concomitant ankle disorders, such as anterior ankle impingement syndrome (AAIS), lateral ankle instability (LAI), and osteochondral lesion of the talus (OLT), allows for early return to athletic activity. METHODS: Ninety-seven patients who engaged in athletic activity (mean age 27 [range 18-43] years) and were treated by a hindfoot endoscopic approach for PAIS alone or simultaneously for PAIS and concomitant ankle disorders were included in this study...

Over the past 4 years, our pediatric orthopedic unit has developed a new hybrid protocol combining the advantages of Ponseti's method and the French functional physiotherapy method. Sixty-one patients (92 feet) completed treatment. Clubfoot was unilateral in 30 (49.2%) patients and bilateral in 31 (50.8%) patients. The mean Dimeglio score at the start of treatment was 13.5/20 (range: 6/20-19/20). All patients had clinical and radiographic follow-up for at least 2 years (range: 2-4 years). If orthopedic treatment was ineffective and feet showed no improvement, further surgery was performed...

BACKGROUND AND OBJECTIVES: Peripheral nerve blocks are increasingly used. However, despite low complication rates, concerns regarding local anesthetic systemic toxicity remain. Although recent studies suggest that this severe complication has decreased considerably, there is a paucity of data about it on a national level. We sought to elucidate the incidence of local anesthetic systemic toxicity on a national level and therefore provide guidance toward the need for preparedness in daily anesthetic practice...

Many epidemiologic, clinical, and experimental findings point to sex differences in myofascial pain in view of the fact that adult women tend to have more myofascial problems with respect to men. It is possible that one of the stimuli to sensitization of fascial nociceptors could come from hormonal factors such as estrogen and relaxin, that are involved in extracellular matrix and collagen remodeling and thus contribute to functions of myofascial tissue. Immunohistochemical and molecular investigations (real-time PCR analysis) of relaxin receptor 1 (RXFP1) and estrogen receptor-alpha (ERα) localization were carried out on sample of human fascia collected from 8 volunteers patients during orthopedic surgery (all females, between 42 and 70 yrs, divided into pre- and post-menopausal groups), and in fibroblasts isolated from deep fascia, to examine both protein and RNA expression levels...
