Arthroscopic Management of Pigmented Villonodular Synovitis of the Hip: A Systematic Review.

: Pigmented villonodular synovitis (PVNS) is a benign proliferation of synovial tissue that can cause joint damage. The hip, although less commonly affected than the knee, presents a challenging diagnosis and treatment, with magnetic resonance imaging (MRI) as the gold standard for detection. Surgical excision, arthroscopic or open, is the main treatment approach, but there is no consensus on the best strategy for the hip.

Performance and usability of cardiometabolic point of care devices in Nepal: A prospective, quantitative, accuracy study.

Non-communicable diseases (NCDs), such as cardiovascular disease and diabetes, represent a serious global health concern. There is an urgent need for prompt diagnosis and effective monitoring at point of care, especially in low- and middle-income countries. Here we present the results of a study assessing the quantitative accuracy of two devices that may fit the target product profile for a cardiometabolic point-of-care device.

Challenges in Total Hip Arthroplasty with Prior Spinal Arthrodesis: A Comprehensive Review of Biomechanics, Complications, and Surgical Strategies.

However, the increasing prevalence of THA in individuals with prior lumbar arthrodesis (LA) poses unique challenges. This review delves into the biomechanical alterations, complications, and surgical strategies specific to this patient subset, highlighting the need for tailored preoperative assessments and planning.

Understanding of and attitudes towards nursing education reform at medical colleges in Kyrgyzstan: A mixed-method study.

Aim: To determine teachers' understanding of and attitudes towards nursing education reform at four medical colleges in Kyrgyzstan.

Background: The quality of nursing education at undergraduate and postgraduate levels has a major impact on patient outcomes and the development of nursing as a profession and a science.

Introduction: Lower middle-income countries have sought to advance their nursing education by adopting the experiences of high-income countries.

Simulation to become a better neurosurgeon. An international prospective controlled trial: The Passion study.

Introduction: Surgical training traditionally adheres to the apprenticeship paradigm, potentially exposing trainees to an increased risk of complications stemming from their limited experience. To mitigate this risk, augmented and virtual reality have been considered, though their effectiveness is difficult to assess.

Research Question: The PASSION study seeks to investigate the improvement of manual dexterity following intensive training with neurosurgical simulators and to discern how surgeons' psychometric characteristics may influence their learning process and surgical performance.

Arthroscopic Reduction and Fixation of a Pipkin Type-I Femoral Head Fracture.

Background: This video article describes the technique for arthroscopic reduction and fixation of Pipkin type-I fractures.

Description: Surgery is performed with the patient in a supine position, with free lower limbs, on a radiolucent table. Arthroscopic superior and anterolateral portals are made similarly to the portals created to evaluate the peripheral compartment during an outside-in (ballooning) technique.

Superior outcomes of total hip arthroplasty without prior lumbar arthrodesis: a systematic review and meta-analysis.

Purpose: The number of patients undergoing total hip arthroplasty (THA) surgery after previous lumbar arthrodesis (LA) is rising. Literature suggests that LA may significantly impact pelvic biomechanics and potentially compromise the success of prosthetic hip replacement. This study aims to evaluate complication rates, dislocation rates, and revision rates in patients with prior LA undergoing THA surgery compared to those undergoing THA surgery without prior LA.

Arthroscopic assistance during open reduction and fixation for complex acetabular fractures.

Achieving an anatomical reduction in acetabular fracture is essential but may also be challenging. Most of complex fractures are treated with anterior approaches without direct visualization of the acetabular surface. In this paper, we present the surgical technique for arthroscopic assistance during open reduction and fixation for complex acetabular fractures.

Impact of three-dimensional printed planning in Paprosky III acetabular defects: a case-control and cost-comparison analysis.

Purpose: The main challenges in revision total hip arthroplasty (rTHA) are the treatment of the bone loss and the pre-operative planning. 3D-printed models may enhance pre-operative planning. The aim of the study is to compare the intra- and peri-operative results and costs for Paprosky type 3 rTHAs planned with 3D-printed models to ones accomplished with the conventional imaging techniques (X-rays and CT scan).

Dynamic evaluation of THA components by Prosthesis Impingement Software (PIS).

Background and aim of the work Implant dislocation in total hip arthroplasties (THA) is a common concern amongst the orthopedic surgeons and represents the most frequent complication after primary implant. Several causes could be responsible for the dislocation, including the malpositioning of the components. Conventional imaging techniques frequently fail to detect the mechanical source of dislocation mainly because they could not reproduce a dynamic evaluation of the components.

Modified Dunn procedure versus percutaneous pinning in moderate/severe stable slipped capital femoral epiphyses.

Background: The modified Dunn procedure (MDP) has risen enthusiasm in treating slipped capital femoral epiphyses (SCFE) due to the anatomic reduction and high patients' satisfaction rates at long-term follow-up. Main aim of this study is to compare clinical and radiographic outcomes of 2 cohorts with moderate to severe stable SCFE treated by MDP and fixation.

Methods: Medical records were analysed to collect demographic data, comorbidities and time from slip to surgery.

3D-Printed Surgical Guiding System for Double Derotational Osteotomy in Congenital Torsional Limb Deformity: A Case Report.

Case: A 19-year-old woman with persistent anterior knee pain was diagnosed with a complex tibial and femoral torsional deformity (26° of femoral anteversion and 49° of tibial external rotation). To achieve the correct realignment of the lower limb, rotational double osteotomies were needed. After planning the correction on the computed tomography scan and three-dimensional (3D) model, a custom-made 3D-printed guiding system was produced to support the surgery.

Understanding the Dynamics of the COVID-19 Pandemic: A Real-Time Analysis of Switzerland's First Wave.

Since the novel coronavirus outbreak of SARS-CoV-2 from the first cases whereof were reported in Wuhan, China, in December 2019, our globalized world has changed enormously. On the 11th of March 2020, the World Health Organization (WHO) declared COVID-19 a pandemic, and nations around the world have taken drastic measures to reduce transmission of the disease. The situation is similar in Switzerland, a small high-income country in Central Europe, where the first COVID-19 case was registered on the 25th of February 2020.

Fixation plus acute arthroplasty for acetabular fracture in eldery patients.

Objective: in elderly patients reduction and fixation of acetabular fractures showed poor outcomes in fracture patterns where cartilage comminution/impaction and/or femoral head dislocation are present; acute arthroplasty with standard uncemented hemispherical cups and posterior plating has been recently proposed, we report on its safety and effectiveness.

Methods: we used this technique to manage 67 displaced acetabular fracture but both column in patients older than 65 years old.

Results: fractures of posterior column and/or wall with severe cartilage involvement may be treated safely with acute THA.

Hip morphology in slipped capital femoral epiphysis.

Several mechanical factors have been related to slipped capital femoral epiphysis (SCFE). Main aim of this study is to investigate the acetabular coverage and acetabular version in unilateral SCFE hips in order to detect a potential pincer-type deformity as predisposing factor; second, we compared those measurements either to the contralateral, uninvolved hips either to a matched healthy control population. A total of 85 patients treated for unilateral SCFE were retrospectively reviewed.
