Mobility of the lumbo-pelvic-hip complex (spinopelvic mobility) and sagittal spinal alignment - implications for surgeons performing hip arthroplasty.

Introduction: The optimal positioning of the hip prosthesis components is influenced by the mobility and balance of the spine. The present study classifies patients with pathology of the spino-pelvic-hip complex, showing possible methods of preventing hip dislocations after arthroplasty.

Hypothesis: Hip-Spine Classification helps arthroplasty surgeons to implant components in more patient-specific position.

An Analysis of the Preoperative Factors, Spinopelvic Mobility and Sagittal Spinal Alignment in Pre-THA Patients.

Hip arthroplasty is a very effective medical procedure. The optimal positioning of the components and the functioning of the endoprosthesis are influenced, among other things, by the mobility and balance of the spine. The aim of the study was to analyze the factors influencing the mobility of the lumbar-pelvic-iliac complex (spinopelvic mobility) together with the assessment of sagittal spinal alignment in patients prior to THA (total hip arthroplasty).

Is the Synovium the First Responder to Posttraumatic Knee Joint Stress? The Molecular Pathogenesis of Traumatic Cartilage Degeneration.

Objective: The aim of this study was to evaluate if a similar catabolic and inflammatory gene pattern exists between the synovium, hyaline cartilage, and blood of patients with the knee joint tissues and if one precedes the other.

Design: A total of fifty-eight patients (34 females and 24 males) with a mean age of 44.7 years (range, 18-75) underwent elective knee arthroscopy due to previously diagnosed pathology.

Early Results of Total Cementless Hip Joint Arthroplasty with a Conical Screw Cup.

Background: With the development of hip arthroplasty, there are increasingly more indications for effective use of this surgical method. Endoprostheses are now being more and more commonly used in difficult cases of secondary coxarthrosis and in increasingly younger patients. The aim of this study is to present the early results of hip joint arthroplasty with the Zweymüller conical screw cup.

More than 20 years of experience with Dega transiliac osteotomy in the treatment of dislocated hip joints in children with cerebral palsy.

Cerebral palsy in children, which is the result of a nonprogressing damage to the central nervous system, causes motor and posture disorders that change with age. The level of child activity correlates with the hip dislocation risk. It most often affects nonwalking patients and those with tetraparesis or oblique pelvis.

Influence of Vibroacoustic Therapy on Local Status and Rehabilitation of Post-TKR and Post-THR patients.

Background: Rehabilitation following major joint replacement surgery is an extremely important part of complementary treatment after the surgical procedure. To obtain the best final treatment outcome possible, apart from improvements in surgical technique, new methods of rehabilitation are still being sought and implemented to increase its effectiveness, safety and patient comfort. One such technique is vibroacoustic therapy, a method of treatment based on the direct transmission of audible sound vibrations through a sound transmitter to the patient's body.

The return to professional activity patients treated surgically due to advanced gonarthrosis.

Objectives: The goal of this work is to analyze the issue of return to professional activity by working-age patients who have been treated surgically with total knee arthroplasty (TKA) due to gonarthrosis.

Material And Methods: Overall, 88 working-age patients were examined, with a total of 91 TKA procedures performed due to advanced gonarthrosis. The average age of the patients was 54.

The Jumper's Knee - a New Look at Non-surgical Treatment. Pilot Study.

Background: There are many opinions and views regarding the methods of treatment of patellar ligament enthesopathy. No gold standard of treatment exists. This paper presents our approach involving conservative treatment and an appropriate rehabilitation regime.

The Influence of Hippotherapy on the Body Posture in a Sitting Position among Children with Cerebral Palsy.

The purpose of this study was to assess the influence of hippotherapy (therapy with horses) on posture and body function among children with cerebral palsy. A case-control study included forty-five children aged 6-12 years, classified as Gross Motor Function Classification System (GMFCS) level I or II, with spastic diplegia or hemiplegia. The participants were randomly divided into three groups: study I (n = 15), study II (n = 15) and control (n = 15).

Contribution of Bone Tissue to Regulation of Calcium and Phosphate Metabolism. Role of FGF23 and Klotho Protein.

Bone tissue actively contributes to the regulation of systemic homoeostasis, and particularly the maintenance of calcium-phosphate balance. The parathyroid hormone-vitamin D feedback axis is balanced by the recently discovered bone-FGF23-kidney hormonal axis. An active complex consisting of FGF23, a receptor and Klotho protein blocks phosphate reabsorption in the proximal tubules, increasing urine phosphate levels and decreasing blood phosphate levels.

Prevalence of Lower Limb Defects in Children in Chosen Kindergartens of the Łódź Agglomeration.

Background: Posture disorders not treated in early childhood may lead to serious diseases and dysfunctions later. The aim of the study was to assess the incidence of lower limb defects in pre-school children.

Material And Methods: The study covered 513 children (252 girls and 261 boys) aged 4-6, in chosen kinder-gartens of the Łódź agglomeration .

Lateral Extra-articular Tenodesis with Iliotibial Band Strip - a Solution for Anterolateral Instability?

It is widely acknowledged that anterior cruciate ligament (ACL) injury is the cause of anterolateral insta-bility, but in some cases not only the ACL ruptures, but also anterolateral structures (ALS), including the antero-lateral ligament. Their insufficiency may be the cause of residual instability after ACL reconstruction, which significantly increases the risk of graft rupture. In the past, anterolateral instability caused by ACL injury was treat-ed with extra-articular reconstructions, including lateral extra-articular tenodesis.

Evaluation of Selected Parameters of Calcium and Phosphate Metabolism in Children with Adolescent Idiopathic Scoliosis.

Background: The multifactor aetiology of adolescent idiopathic scoliosis is commonly acknowledged. Both multivariate analyses of large study groups and the search for causes of adolescent idiopathic scoliosis and its progression in individual patients indicate that the aetiopathogenesis of this disorder is remarkably complex. The discovery of novel bone turnover markers, such as Klotho protein and FGF-23, means that their role in this condition also has to be considered.

Feet Deformity and Gait Disturbance in a Patient with Pachydermoperiostosis (PDP). Case Study.

Pachydermoperiostosis is a rare condition representing a primary form of hypertrophic osteoarthropathy. It presents in different stages. Patients often overlook early symptoms, because they are benign.

Effect of Photobiomodulation Therapy on the Increase of Viability and Proliferation of Human Mesenchymal Stem Cells.

Background And Objectives: We have investigated how low intensity laser irradiation emitted by a multiwave-locked system (MLS M1) affects the viability and proliferation of human bone marrow mesenchymal stem cells (MSCs) depending on the parameters of the irradiation.
