Expression Pattern of iNOS, BCL-2 and MMP-9 in the Hip Synovium Tissue of Patients with Osteoarthritis.

Hip osteoarthritis (HOA) is characterized by degradation of the cartilage and synovitis. However, the pathohistological effects of synovial tissue inflammation on HOA are not clear. The aim of this study was to evaluate the expression of iNOS, BCL-2 and MMP-9 markers in different synovial cell populations.

Postoperative Regional Analgesia Is Effective in Preserving Perforin-Expressing Lymphocytes in Patients After Total Knee Replacement.

BACKGROUND Pain and surgical stress cause a pro-inflammatory response followed by downregulation of the immune response, which can increase the incidence of postoperative complications, such as infections or prolonged wound healing. T lymphocytes and natural killer (NK) cells have cytotoxic potential and are crucial components of cellular immunity, which is important for maintenance of immune balance. The aim of this study was to analyze the effects of 3 types of postoperative analgesia on the preservation and cytotoxic potential of T lymphocytes, NK cells, and their subpopulations, as well as NKT cells, in patients after total knee replacement (TKR) to find the most effective analgesic technique for mitigating immune suppression.

Functional recovery after muscle sparing total hip arthroplasty in comparison to classic lateral approach - A three years follow-up study.

Background: The muscle sparing total hip arthroplasty had generated a distinguishable interest, in both the patients and the surgeons, but its benefits are still often questioned. The main idea of this study was to compare the functional clinical outcome of the patients operated by the anterolateral approach with a muscle-sparing technique (modified Watson-Jones approach), and the patients operated by modified direct lateral approach without the muscle-sparing technique (Bauer/Hardinge approach).

Methods: The patients (N = 130) were divided into two groups: 68 in a standard method group (STAND) and 62 patients in a muscle sparing surgery group (MSS).

Complications in leg lengthening using an Ilizarov external fixator and intramedullary alignment in children: comparative study during a fourteen-year period.

Background: The purpose of this retrospective study was to evaluate the complications associated with leg lengthening in children treated with the Ilizarov external fixator (IEF) and compare them between two groups of patients: one group was treated using an IEF alone and the other group was treated using an IEF in association with intramedullary alignment (IA).

Patients And Methods: The study was performed at the University Children's Hospital in Belgrade, Serbia during a fourteen-year period (from 2000 to 2014). Complications occurred in 73 paediatric patients who underwent the leg lengthening procedure.

Ultrasound-assisted calcaneoplasty.

Purpose: The endoscopic technique for resection of a postero-superior part of calcaneus served as a golden standard during the last 10 years, and it has mostly replaced the open techniques. In an effort to reduce the morbidity and the recovery time, we had introduced the ultrasound-assisted technique.

Methods: In the period of 1 year, 15 patients with the prominent postero-superior part of calcaneus and retrocalcaneal bursitis were operated through the single skin incision using the ultrasound-assisted technique.

Physiological load and posture control thresholds.

The aim of the study was to evaluate the influence of the physiological load on postural control. Special attention was directed toward the identifying the intensity level in which the major deterioration in balance abilities occurs. Thirty subjects randomly divided into two groups performed multistage all-out exertion protocol on cycle-ergometer with measurements of ventilatory-metabolic and subjective parameters of exertion.

The "cello technique": a new technique for ultrasound-assisted calcaneoplasty.

The "cello technique" is a new calcaneoplasty technique for the treatment of Haglund disease. It is an ultrasound-assisted technique for resection of the posterosuperior part of the calcaneus. It is possible to resect the posterosuperior part of the calcaneus under direct ultrasound control with the patient in the prone position, with a dorsally positioned ultrasound probe, in line with the Achilles tendon fibers (sagittal line), and with the abrader in the posteromedial working portal.

New "L value" parameter simplifies and enhances hip ultrasound interpretation in the detection of developmental dysplasia of the hip.

Purpose: The purpose of this study was to simplify and enhance the ultrasound (US) analysis of the infant's hip by introducing a novel parameter named "L value" into the widely used Graf method.

Methods: We analysed 508 ultrasonographic images of the hips in infants aged three months. The images were first evaluated using the Graf measurements.

Bilateral congenital dislocation of the knee with ipsilateral developmental dysplasia of the hip--report of three patients.

Congenital dislocation of the knee (CDK) is a very rare condition. Here we report our strategy and results in treatment of three children with CDK. All three patients were treated with conservative method, and only one had underwent a surgical procedure on one knee.

The influence of test repetition on bipodal visually controlled static and dynamic balance.

This study explores the influence of test repetition on bipodal visually controlled balance, both static and dynamic. Our goal was to get an insight into the pattern of changes in posture maintenance results during repeated balance tests. Fifteen young, healthy male recreational athletes were tested for static and for dynamic balance using KAT 2000 balance platform.

Bone allograft provides bone healing in the medial opening high tibial osteotomy.

Various materials are used to fill osteotomy defects created in the medial opening wedge high tibial osteotomy (MOWHTO). Our hypothesis was that a bone allograft would provide the osteotomy site bone healing within the expected time. We performed the MOWHTO using a cancellous bone allograft in 310 knees in 284 patients between 2000 and 2005.

Limb salvage surgery in Enneking's stage III a--a case of leiomyosarcoma.

Limb saving surgery is today's tendency in treating the musculoskeletal tumours. Preserving the limb should not only pursue a good oncological and functional result but also aim at good psychological outcome. Our aim was to treat a very rare case of proximal femoral leiomyosarcoma with present solitary lung metastasis by conservative operative procedures.

A new tibial torsiometer applicable to clinical practice.

This study evaluated a new tibial torsiometer that is universally applicable to all limb sizes and requires no special training, jigs, or radiographic equipment. To compare the reliability of measurements obtained with the torsiometer, 160 tibias were evaluated with both the torsiometer and computed tomography. Results for both methods were identical in 51 tibias, within 1 degrees in 66 tibias, and within 2 degrees in 43 tibias.

Synovial chondromatosis of the pisotriquetral joint with secondary osteoarthritis: case report.

There are only a few reported cases of synovial chondromatosis affecting pisotriquetral joint (PT). Osteoarthritis of the PT is also rare and can be as disabling as osteoarthritis of any other joint. We report this to be the unique case of synovial chondromatosis of the PT joint with secondary osteoarthritis.

The rational strategies for detecting developmental dysplasia of the hip at the age of 4-6 months old infants: a prospective study.

Using ultrasound in evaluation of infant's hip development can reduce surgical procedures, hospitalization and late presentation of developmental dysplasia of the hip (DDH). The increasing incidence of DDH after ultrasound examination is observed and published by many authors. In a prospective study, radiograph of every single ultrasonographic positive hip in infants older than three months, was taken and analyzed in order to see whether it affects infants splintage rate in treating DDH.
