Clinical Observations of the Effectiveness of the Masquelet Induced Membrane Technique in the Treatment of Critical Long-Bone Defects of the Lower and Upper Extremities.

Successful treatment of severe trauma and fractures of the long bones with successful healing and bone union is still a significant challenge for surgeons. Unfortunately, up to 10% of long-bone fractures develop bone healing disorders. The aim of this study was to evaluate the results of treating bone defects with different etiologies in the upper and lower extremities using the induced membrane technique.

Bone Quality Assessment Before Total Hip Arthroplasty: The Role of Densitometry.

Background Total hip arthroplasty (THA) is effective in the treatment of hip osteoarthritis. Radiographic evaluation, standard in THA planning, is sufficient in examining hip anatomy, although it may not precisely assess bone quality. A routinely implemented method in bone quality assessment is densitometry.

Assessment of the Length of the Pedicle of the Anterolateral Thigh Flap.

Purpose To estimate the length of the pedicle of the anterolateral thigh flap (ALT) and to assess how this length corresponds with the distances between the anatomical landmarks. Methods The study group consisted of patients who underwent computed tomography angiograms ranging minimally from the anterior superior iliac spine (ASIS) superiorly and tibia inferiorly. In the study we included 44 patients.

Corrective Osteotomies in Severe Non-Idiopathic Lower Limb Alignment Disorders in the Aspect of Future Joint Endoprosthesis-A Perspective Study.

The aim of this study was to retrospectively evaluate the effectiveness of corrective osteotomies in lower limb axis disorders at different levels of non-idiopathic (post traumatic, developmental, post-septic) etiology. A total of 50 patients were divided into three groups: A-thigh segment alignment disorder (24 patients); B-tibia segment alignment disorder (18 patients); C-thigh and tibia segment alignment disorder (8 patients). Radiological evaluation of digital lower limb postural X-ray was performed laterally and for AP, and included mLPFA, mLDFA, MAD, CORA coronal and sagittal plane parameters for the femur segment and mMPTA, mLDTA, MAD, CORA coronal and sagittal plane for the tibia segment.

Long-term sensibility outcomes of secondary digital nerve reconstruction with sural nerve autografts: a retrospective study.

Background: Recovery of sensibility after digital nerve injury is crucial for restoring normal hand function. We evaluated long-term outcomes of digital nerve reconstruction with autografts.

Methods: This retrospective study included patients who underwent secondary reconstruction of digital nerves with nerve autografting.

The origin of the medial femoral circumflex artery, lateral femoral circumflex artery and obturator artery.

Introduction: The most significant blood vessel supplying the hip joint is the medial femoral circumflex artery (MFCA). MFCA with lateral femoral circumflex artery (LFCA) are the first branches of the deep femoral artery (DFA) or they originate directly from the common femoral artery (CFA) or superficial femoral artery (SFA).

Purpose And Methods: We analyzed 100 CT angiogram of the hip region [72 men, 28 women; mean age 46.

Hip osteonecroses treated with calcium sulfate-calcium phosphate bone graft substitute have different results according to the cause of osteonecrosis: alcohol abuse or corticosteroid-induced.

Introduction: The aim of the study was to assess the factors influencing the final results of treatment of the femoral head osteonecrosis (ONFH) with core decompression and bone substitute grafting. The special interest was focused on comparison between alcohol- and steroid-induced ONFHs.

Material And Methods: In this prospective study, a total of 53 patients (58 hips) in the mean age of 35.

The blood supply to the femoral head after posterior fracture/dislocation of the hip, assessed by CT angiography.

The femoral head receives blood supply mainly from the deep branch of the medial femoral circumflex artery (MFCA). In previous studies we have performed anatomical dissections of 16 specimens and subsequently visualised the arteries supplying the femoral head in 55 healthy individuals. In this further radiological study we compared the arterial supply of the femoral head in 35 patients (34 men and one woman, mean age 37.

Absolute counts of peripheral blood leukocyte subpopulations in intraabdominal sepsis and pneumonia-derived sepsis: a pilot study.

The leading pathophysiological changes during sepsis include systemic abnormalities in the immune response. Due to the general character of these disturbances, sepsis is usually studied as a homogenous clinical condition. We aimed to compare the immune response in intraabdominal sepsis (IAS) and pneumonia-derived sepsis (PDS).

Imaging the vascularisation of the femoral head by CT angiography.

The femoral head receives its blood supply primarily from the medial femoral circumflex artery, with its deep branch being the most important. In a previous study, we performed classical anatomical dissections of 16 hips. We have extended our investigation with a radiological study, in which we aimed to visualise the arteries supplying the femoral head in healthy individuals.

Open reduction and internal stabilization of acetabular fractures in pregnancy--case report.

Pelvic and acetabular fractures are common injuries in the time of rising traffic level and often affect young people, that's why this kind of injury during pregnancy must be considered. Despite lapse of years this subject is seldom raised in literature. Conservative treatment was usually recommended.

Procalcitonin in early onset ventilator-associated pneumonia.

Background: Ventilator-associated pneumonia (VAP) is a significant problem in intensive care and there exists great demand for a suitable biomarker. Procalcitonin (PCT) has been proposed as a candidate marker.

Aim: To assess the clinical usefulness of monitoring PCT concentrations in non-surgical patients with early onset VAP.

Sepsis immunopathology: perspectives of monitoring and modulation of the immune disturbances.

Septic syndromes are the main cause of death in the intensive care units and although the mortality rates is slowly decreasing, the occurrence of the disease has been increasing. The pathogenesis of sepsis includes countless disturbances of the host immune system starting with a harmful, infection-triggered exaggerated inflammatory cascade, followed by the development of an immunoparalysis state. The latter contributes to the failure in pathogen eradication and leads to secondary infections, which are often the cause of fatal complications.

Anatomy of the medial femoral circumflex artery with respect to the vascularity of the femoral head.

We performed a series of 16 anatomical dissections on Caucasian cadaver material to determine the surgical anatomy of the medial femoral circumflex artery (MFCA) and its anastomoses. These confirmed that the femoral head receives its blood supply primarily from the MFCA via a group of posterior superior nutrient arteries and the posterior inferior nutrient artery. In terms of anastomoses that may also contribute to the blood supply, the anastomosis with the inferior gluteal artery, via the piriformis branch, is the most important.

[Infection with multidrug-resistant pathogens].

Background: Intensive therapy units are the places where pathogens can easily spread. Improper antibiotic therapy contributes to the selection of new strains called multidrug-resistant, extensively drug-resistant or pandrug-resistant. For ITU patients, such pathogens are particularly dangerous.
