Effectiveness of Virtual Surgical Planning and Three-Dimensional Anatomical Models in Radiological Reconstruction of Center of Rotation and Pelvic Brim in Patients with Anterior Column Defects Requiring Revision Hip Arthroplasty.

The aim of this study was to show that virtual surgical planning (VSP) and printed anatomical models support the reconstruction of the center of rotation (COR) and pelvic BRIM during revision hip surgery using a dual-mobility revision cup system in patients with anterior pelvic column damage and soft tissue envelope deficiency. Patients with anterior pelvic column damage and soft tissue envelope deficiency underwent revision hip arthroplasty. Virtual planning included assessment of bone segmentation, positioning of the cementless revision cup while maintaining the COR, and the assumed inclination and anteversion angles.

Optimization of Revision Hip Arthroplasty Workflow by Means of Detailed Pre-Surgical Planning Using Computed Tomography Data, Open-Source Software and Three-Dimensional-Printed Models.

Background: In revision hip arthroplasty (RHA), establishing the center of rotation (COR) can be technically challenging due to the acetabular bone destruction that is usually present, particularly in severe cases such as Paprosky type II and III defects. The aim of this study was to demonstrate the use of open-source medical image reconstruction software and low-cost 3D anatomical models in pre-surgical planning of RHA.

Methods: A total of 10 patients, underwent RHA and were included in the study.

Localization of the gracilis muscle motor points - key considerations for botulinum neurotoxin injection and electrical stimulation.

The aim of this study is to locate the motor points in the gracilis muscle to improve muscle function maintenance and treatment of spasticity.

Material And Methods: Ninety-three gracilis muscles (49 right, 44 left), fixed in 10% formalin solution, were subjected to the research.

Long Term Effectiveness of ESWT in Plantar Fasciitis in Amateur Runners.

Background: Shock wave therapy is one of the modern methods of treatment used to treat diseases of muscles, tendons, and entheses in orthopedics, as well as in sports medicine. The therapy is increasingly used in the treatment of plantar fasciitis-a disease that is very difficult and burdensome to treat. Where basic conservative treatment for heel spurs fails, the only alternative consists of excision of the bone outgrowth, and shock wave therapy: a modern, minimally invasive, and relatively safe method.

Milk Formula Enriched with Sodium Butyrate Influences Small Intestine Contractility in Neonatal Pigs.

Butyrate, a by-product of gut bacteria fermentation as well as the digestion of fat in mother's milk, exerts a wide spectrum of beneficial effects in the gastrointestinal tissues. The present study aimed to determine the effects of sodium butyrate on small intestine contractility in neonatal piglets. Piglets were fed milk formula alone (group C) or milk formula supplemented with sodium butyrate (group B).

Assessment of the deformation model of the proximal tibia in the course of degenerative disease: analysis of the 3-dimensional mathematical model.

Background: The high tibial osteotomy (HTO) is an effective knee-saving procedure, which relieves arthritis symptoms and prolongs the life of the knee joint. This procedure requires detailed preoperative planning. Usually, the contralateral side is used as a template for this purpose.

Let's Play the fMRI-Advantages of Gamified Paradigm in Examining the Motor Cortex of Young Children.

Background: Performing functional magnetic resonance imaging (fMRI) examination is difficult when a child needs to stay awake and cooperate. Many techniques help to prepare them for the study but without modification of the examination protocol. The objective of this research was to prepare a gamified motor paradigm (“computer game”) that will improve the fMRI examination of young children.

A Review of the Clinical Effectiveness and Safety of Hybrid Cooperative Complexes in Intra-articular Viscosupplementation.

Viscosupplementation by intra-articular (i.a.) injection of the non-sulfated glycosaminoglycan (GAG) hyaluronic acid (HA) is a conservative therapy widely accepted in clinical practice for the management of osteoarthritis (OA) and joint diseases.

Translation and rotation analysis based on stress MRI for the diagnosis of anterior cruciate ligament tears.

Background: Due to the increasing need for a detailed biomechanical analysis of anterior cruciate ligament (ACL) lesions, the aim of the study was to develop a method of direct measurement of the three-dimensional tibial translation and rotation based on stress MRI.

Methods: For the purpose of the study, thirty patients with acute ACL rupture and 17 healthy control subjects were selected. Based on clinical examination, they were qualified for MRI examination using the Arthroholder Device prototype to perform anterior tibial translation.

Assessment of morphological differences of the proximal tibia in healthy knees: analysis of the 3-dimensional mathematical model.

Background: High tibial osteotomy and many orthopedic surgical procedures around the knee joint requires precise preoperative planning. In-depth knowledge of the tibial plateau morphology is necessary to limit intraoperative complications like lateral hinge fracture. No studies were exploring the differences in proximal tibia surface geometry, in regards to gender and laterality, using a mathematical model.

The knee function of the soccer players after ACLR is comparable with non-injured controls: A case-control study.

Purpose: Many studies report a high primary success rate of ACL reconstruction (ACLR), with an increased risk of decline in knee performance correlating with the time passed since surgery. Only one study has compared male soccer players after ACLR to a matched control group of uninjured players in terms of their return to sport and performance. The purpose of this cross-sectional case-control study was to determine the knee performance between soccer players after ACLR and control group matched by age, sex, and professional experience.

The popliteofibular ligament: a cadaveric ultrasound study.

Objective: The popliteofibular ligament (PFL) is an important stabilizer of the knee found within the posterolateral corner (PLC) of the joint. Injuries to the PLC can cause substantial patient morbidity. Accurate PFL visualization has been historically challenging, impeding injury diagnosis and treatment.

Smoking is associated with prolonged time of the return to daily and sport activities and decreased knee function after meniscus repair with outside-in technique: Retrospective cohort study.

Background: Arthroscopic repair of post-traumatic meniscal lesion is one of the most common procedures in the orthopedics. Although algorithm of the treatment of meniscal lesion, this procedure is rarely discussed in combination with smoking as a risk factor for the meniscal healing.

Purpose: The aim of this study was to assess the knee function, and the amount of time needed to return to daily and sport activities after the non-bucket-handle meniscal outside-in repair depending on Tobacco use.

Mini-Invasive, Ultrasound Guided Repair of the Achilles Tendon Rupture-A Pilot Study.

Percutaneous acute Achilles tendon rupture suturing has become a leading treatment option in recent years. A common complication after this mini-invasive procedure is sural nerve injury, which can reduce the patients' satisfaction and final outcomes. High-resolution ultrasound is a reliable method for localizing the sural nerve, and it can be performed intra-operatively; however, the long-term results are yet unknown.

Endorsement by Central European experts of the revised ESCEO algorithm for the management of knee osteoarthritis.

Osteoarthritis (OA) is characterized by deterioration of the joints and associated with considerable pain and disability. OA is a chronic disease that requires intervention with both non-pharmacological and pharmacological treatment modalities and, inevitably, disease progression may necessitate successive treatments throughout the course of the disease. There is increasing data on the shortfalls of current pharmacological treatment of OA, and safety concerns associated with analgesic therapy use in OA arising from increasing evidence of gastrointestinal, cardiovascular, hepatic and renal adverse events with paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs).

Adenosine and the homeostatic control of sleep: effects of A1 receptor blockade in the perifornical lateral hypothalamus on sleep-wakefulness.

The orexinergic neurons of the lateral hypothalamus (LH) are critical for wakefulness [McCarley RW (2007) Neurobiology of REM and NREM sleep. Sleep Med 8:302-330]. Recent evidence suggests that adenosine (AD), a homeostatic sleep factor, may act via A1 receptor (A1R) to control orexinergic activity and regulate sleep-wakefulness [Thakkar MM, Winston S, McCarley RW (2002) Orexin neurons of the hypothalamus express adenosine A1 receptors.
