The Preparation and Biological Testing of Novel Wound Dressings with an Encapsulated Antibacterial and Antioxidant Substance.

Chronic wounds represent a significant socio-economic problem, and the improvement of their healing is therefore an essential issue. This paper describes the preparation and biological properties of a novel functionalized nanofiber wound dressing consisting of a polycaprolactone nanofiber carrier modified by a drug delivery system, based on the lipid particles formed by 1-tetradecanol and encapsulated gentamicin and tocopherol acetate. The cytotoxicity of extracts was tested using a metabolic activity assay, and the antibacterial properties of the extracts were tested in vitro on the bacterial strains and .

PURPOSE OF THE STUDY Acromioclavicular (AC) joint dislocation and its surgical treatment still raises a number of questions that remain to be answered. In some types of dislocations, Rockwood type III in particular, the indication for surgical treatment as such is relative. There are numerous techniques and implants available for the reconstruction of AC joint.

Systematic Literature Review and Expert Opinion for the Use of Viscosupplementation with Hyaluronic Acid in Different Localizations of Osteoarthritis.

Osteoarthritis (OA) is a significant cause of disability. Considering the increasing diffusion of the viscosupplementation (VS) with hyaluronic acid (HA), the International Symposium Intra Articular Treatment (ISIAT) appointed a Technical Expert Panel (TEP) to identify the criteria for successful VS with a specific HA in OA; this through a systematic literature review (SLR), performed following the PRISMA guidelines interrogating Medline, Embase, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Grey Matters and American College of Rheumatology (ACR/EULAR) databases and the opinion of international experts. The research included only studies on adults and humans without limitations of language or time of publication.

[Concentration of Hyaluronic Acid in Synovial Fluid as an Indicator of Severity and Degree of Impairment in Patients Suffering from Gonarthrosis].

PURPOSE OF THE STUDY Hyaluronic acid is a major component of synovial fluid and an indicator of joint viscosity and viscoelasticity. Decreased concentrations of hyaluronic acid in the synovial fluid indicate the severity of osteoarthritis. The aim of the study was to determine the concentrations of hyaluronic acid in the synovial fluid and to evaluate the correlation with the severity of osteoarthritis determined based on the radiological criteria (evaluation according to X-ray classification) and the physicochemical criteria (measurement of synovial fluid osmolality).

PURPOSE OF STUDY Osteochondritis dissecans (OCHD) is an increasingly diagnosed disease among adolescent patients. It is a condition affecting subchondral bone and the lining cartilage. If left untreated, it can cause destruction of cartilage of the affected joint leading to early development of arthrosis.

[New Technique of Anterior Cruciate Ligament Reconstruction Using Hamstrings - the Surgical Instrumentation Set].

PURPOSE OF THE STUDY The success rate of the anterior cruciate ligament (ACL) reconstruction depends on the fixation of the graft, the surgical technique and, of course, on the experience of the operating surgeon. The authors present the development of the construction of the new instrumentation set designed to manage the ACL lesions using the hamstring (HS) tendons. The study is divided into two parts, of which part one focuses on construction, methods and work with new instruments, while part two presents the outcomes of the surgery.

[Treatment of pelvic avulsion fractures in children and adolescents].

Introduction: Paediatric avulsion fractures of the pelvis and hip joint are rare injuries most commonly associated with a rapid muscle contraction of the respected apophysis, which is the weakest component of the growing skeleton. The chosen therapy option can be either conservative or surgical.

Methods: We present a cohort of 69 patients treated for an apophyseal avulsion fracture of the anterior superior / inferior iliac spine, the lesser and greater trochanters iliac crest and the ischial tubercle.

[Rehabilitation after total knee and hip arthroplasty].

The main purpose of total hip replacement is to relieve hip pain and recover the lost mobility of the joint. The postoperative functionality of the hip endoprosthesis is closely related to proper physiotherapy. A good range of motion, sufficient pain reduction and minimum disruption to the muscle tissues are conditions allowing the patients to perform individualized muscle strengthening exercises and to exercise the newly gained mobility, following practice sessions during the early postoperative period still in hospital.

[Avascular necrosis of the femoral head].

Avascular necrosis of the femoral head in adults is not common, but not too rare diseases. In orthopedic practice, it is one of the diseases that are causing implantation of hip replacement at a relatively early age. In the early detection and initiation of therapy can delay the implantation of prosthesis for several years, which is certainly more convenient for the patient and beneficial.

[Limb shortening in the management of leg length discrepancy].

Limb shortening is an option to manage leg length discrepancy. Before skeletal maturity, small length discrepancy between 2 and 5 cm can be corrected by open or closed epiphyseodesis or stapling. All these procedures require exact timing of surgery.

[Femoroacetabular impingement treatment options].

Femoroacetabular impingement syndrome is a very common hip pathology that is responsible for hip pain in patients under 40 years of age. Anatomic changes in hip joint cause labral tears and cartilage dysfunction, both of these conditions cause severe hip pain and often lead to hip arthritis. This syndrome is very common in the population, but very often misdiagnosed and undertreated.

[Primary malignant bone tumors in children possibilities of limb-saving surgery using allografts].

Therapy of primary malignant bone tumors is always multimodal and requires close cooperation of oncologist, orthopedic surgeon, radiologist and others. In our article, we provide a brief overview of the most common malignant bone tumors in pediatric patients and summarize the commonly used therapeutic procedures. Despite advances in cancer treatment radical surgical resection of the tumor is still necessary.

[Use of cultured human autologous bone marrow stem cells in repair of a rotator cuff tear: preliminary results of a safety study].

PURPOSE OF THE STUDY Rotator cuff tears are one of the most frequent shoulder disorders which are often associated with pain and interfere with proper arm function. In order to evaluate the safety and effectiveness of using cultured human autologous mesenchymal stem cells (MSC) applied to the suture site during arthroscopic repair of a rotator cuff tear, a prospective clinical study was designed and started recently at the authors' department. Its primary goal was to evaluate the safety of using cultured human MSCs, the secondary goal then was to study a therapeutic effect of their application.
