Comparing revision rates and survival of pyrocarbon and non-pyrocarbon heads in total shoulder and hemi-shoulder arthroplasty.

Objective: This retrospective, observational study aimed to assess the revision rates and survival curves in total shoulder arthroplasty (TSA) and hemi-shoulder arthroplasty (HSA) patients, including a subanalysis to investigate the impact of a pyrocarbon humeral head in revision rates.

Methods: Data collected from 7 surgeons who performed primary HSA in 92 patients and primary TSA in 508 patients at a large private clinic were analyzed. The study focused on revision rates and identified factors leading to revisions, including rotator cuff insufficiency, dislocation, aseptic loosening, implant material, and glenoid erosion.

No difference in early functional outcome between the direct anterior approach and posterior approach in patients following total hip arthroplasty.

Background: Objective and subjective outcomes in the direct anterior approach (DAA) and posterior approach (PA) in total hip arthroplasty (THA) were assessed in this study, using the Oxford Hip Score (OHS) as primary outcome. Pain, 3 objective performance-based tests, surgical time, blood loss and length of stay were assessed as secondary outcomes.

Methods: Patients with primary end-stage osteoarthritis were prospectively enrolled by shared decision making for the DAA (32 patients) or PA (26 patients).

The minimal important change is not a universal fixed value across diagnoses when using the FAOS and FAAM in patients undergoing elective foot and ankle surgery.

Purpose: This study aimed to calculate region and diagnosis-specific minimal important changes (MICs) of the Foot and Ankle Outcome Score (FAOS) and the Foot and Ankle Ability Measure (FAAM) in patients requiring foot and ankle surgery and to assess their variability across different foot and ankle diagnoses.

Methods: The study used routinely collected data from patients undergoing elective foot and ankle surgery. Patients had been invited to complete the FAOS and FAAM preoperatively and at 3-6 months after surgery, along with two anchor questions encompassing change in pain and daily function.

Diagnostic Accuracy of an Algorithm for Discriminating Presumed Solid and Gaseous Microembolic Signals During Transcranial Doppler Examinations.

Objective: The aim of the work described here was to assess the diagnostic accuracy of a new algorithm (SGA-a) for time-domain analysis of transcranial Doppler audio signals to discriminate presumed solid and gaseous microembolic signals and artifacts (SGAs).

Methods: SGA-a was validated by human experts in an artifact cohort of 20 patients subjected to a 1-h transcranial Doppler exam before cardiac surgery (cohort 1). Emboli were validated in a cohort of 10 patients after aortic valve replacement in a 4-h monitoring period (cohort 2).

Graft failure and revision rate after ACL repair with dynamic intraligamentary stabilization. One-year results of a prospective case series of 155 patients.

Purpose: The aim of this study was to assess graft failure, revision rate, and functional outcomes after treatment of acute ACL rupture with dynamic intraligamentary stabilization (DIS) Ligamys device one year post surgery. Additionally, differences in functional outcome between patients with and without anteroposterior laxity were assessed. It was hypothesized that the failure rate of DIS was non-inferior to that of previously reported ACL reconstruction (10%).

The European Robotic Spinal Instrumentation (EUROSPIN) study: protocol for a multicentre prospective observational study of pedicle screw revision surgery after robot-guided, navigated and freehand thoracolumbar spinal fusion.

Introduction: Robotic guidance (RG) and computer-assisted navigation (NV) have seen increased adoption in instrumented spine surgery over the last decade. Although there exists some evidence that these techniques increase radiological pedicle screw accuracy compared with conventional freehand (FH) surgery, this may not directly translate to any tangible clinical benefits, especially considering the relatively high inherent costs. As a non-randomised, expertise-based study, the European Robotic Spinal Instrumentation Study aims to create prospective multicentre evidence on the potential comparative clinical benefits of RG, NV and FH in a real-world setting.

Self-Warming Blanket Versus Forced-Air Warming in Primary Knee or Hip Replacement: A Randomized Controlled Non-Inferiority Study.

Objective: After primary total knee/hip replacement (TKR or THR respectively) a prosthetic joint infection (PJI) could develop. Hypothermia could raise the risk of infection. Heating by forced-air can disrupt laminar airfl ow in the operation room (OR), potentially raising the risk of infection.

Validation of the Super Simple Hip score combined with the University of California, Los Angeles activity scale for younger patients.

Introduction: Patient-reported outcome measures (PROMs) are used increasingly, but for young patients with hip complaints, traditional scoring systems have a ceiling effect that limits their usability. We developed and validated the Super Simple Hip (SUSHI) score, a PROM specifically targeted at younger patients with hip complaints. Although the SUSHI measured hip problems adequately, the responsiveness of its activity rating component was considered inadequate.

Risk factors for postoperative pain in the first three weeks after arthroscopic or open shoulder surgery.

Introduction: Shoulder surgery is a painful procedure. Adequate postoperative pain control increases patient satisfaction. The objectives of this study were to investigate postoperative pain development in shoulder surgery and to assess risk factors for high postoperative pain.

Outcome after 52 Salto Ankle Prostheses Implanted by a Single Surgeon.

While ankle arthrodesis was traditionally the gold standard method of treatment for disabling end-stage ankle arthritis, total ankle replacement (TAR) has been an acceptable alternative. The satisfaction rate of patients with TAR however differs. The purpose of our study is to investigate whether implant survival and results with special emphasis on the satisfaction rate of patients treated with a TAR implanted by a single surgeon were comparable to the literature.

The influence of food order on postprandial glucose levels in children with type 1 diabetes.

Objective: To evaluate the effect of the order of intake of carbohydrates, protein, and fat on postprandial glucose levels in children with type 1 diabetes (T1D). Our hypothesis was that postprandial glucose levels would be lower when fat and protein are consumed prior to carbohydrates, compared to a meal where all macronutrients are combined.

Methods: A randomized, open-label, within-subject crossover study was conducted.

Safety and effectiveness of selective carotid angioplasty prior to cardiac surgery: a single-centre matched case-control study.

Objectives: Reducing the rate of postoperative stroke after cardiac surgery remains challenging, especially in patients with occlusive cerebrovascular disease. Angioplasty in all patients with high-grade carotid artery stenosis has not been shown to be effective in reducing the post-surgical stroke rate. In this study, we present the initial results of a different approach using selective carotid angioplasty only in patients with poor intracranial collaterals.

Impact of the Haga Braincare Strategy on the burden of haemodynamic and embolic strokes related to cardiac surgery.

Objectives: This study prospectively evaluates the impact of the Haga Braincare Strategy (HBS) on the occurrence of haemodynamic and embolic stroke in a cohort of patients who underwent coronay artery bypass grafting (CABG), valve replacement of a combination of both types of surgery between 2012 and 2015 at the Haga Teaching Hospitals.

Methods: The HBS is a dual strategy based on a preoperative vascular work-up of the cerebral circulation by transcranial Doppler and a perioperative monitoring of the cerebral circulation by cerebral oximetry. Duplex of the carotid arteries and/or computed tomography angiography prior to surgery was performed in high-risk patients.

Ultrasound guided Needling vs Radial Shockwave Therapy in calcific tendinitis of the shoulder: A prospective randomized trial.

Purpose: Ultrasound Needling(UN) and Radial Shockwave(RSWT) aim to dissolve deposits in Shoulder Calcific tendinitis.

Methods: RCT in 25 patients to compare short term effectiveness. Outcome measures were pain and functional outcome at 6 weeks and 1 year and decrease of deposits after 6 weeks.

Epinephrine Diluted Saline-Irrigation Fluid in Arthroscopic Shoulder Surgery: A Significant Improvement of Clarity of Visual Field and Shortening of Total Operation Time. A Randomized Controlled Trial.

Purpose: To determine the influence of epinephrine saline irrigation in therapeutic shoulder arthroscopy procedures on the clarity of arthroscopic view. Three subgroups were analyzed; (1) Bankart/SLAP repairs; (2) rotator cuff repairs; and (3) subacromial procedures without rotator cuff repair. Secondary objectives were to evaluate the influence on total operating time and potential cardiovascular adverse reactions.

Short-Term Clinical Outcome of Hemiarthroplasty Versus Arthrodesis for End-Stage Hallux Rigidus.

Few data are available to compare the outcomes of first metatarsophalangeal joint (MTPJ) hemiarthroplasty and arthrodesis. We included 46 patients who had undergone BioPro(®) first MTPJ hemiarthroplasty and 132 who had undergone arthrodesis, with a minimum follow-up duration of 12 months. The primary outcome was patient satisfaction, which was determined using binominal questions.

Can combining femoral and acetabular morphology parameters improve the characterization of femoroacetabular impingement?

Background: Femoroacetabular impingement (FAI) presupposes a dynamic interaction of the proximal femur and acetabulum producing clinical symptoms and chondrolabral damage. Currently, FAI classification is based on alpha angle and center-edge angle measurements in a single plane. However, acetabular and femoral version and neck-shaft angle also influence FAI.

What ape proximal femora tell us about femoroacetabular impingement: a comparison.

Background: Human hip morphology is variable, and some variations (or hip morphotypes) such as coxa profunda and coxa recta (cam-type hip) are associated with femoroacetabular impingement and the development of osteoarthrosis. Currently, however, this variability is unexplained. A broader perspective with background information on the morphology of the proximal femur of nonhuman apes is lacking.

Coxa recta, coxa profunda and abductor ratio: hip morphology variants compared in an arthroplasty and control population.

Morphology variants of the hip such as coxa recta (aspherical femoral head and/or reduced head-neck concavity) or coxa profunda (overcoverage, or "deep" socket) are associated with cam and pincer impingement respectively, and may ultimately lead to coxarthrosis. Several population studies have documented the prevalence of hip morphotypes, but few studies have examined this prevalence in total hip arthroplasty (THA) patients, or persons without hip symptoms or signs.
We reviewed whether coxa recta and profunda morphotypes were more prevalent in THA patients compared to normal controls.

Mammal hip morphology and function: coxa recta and coxa rotunda.

Using 15 parameters, we provide a systematic description of mammal proximal femoral morphology. We established two types of proximal femoral morphology, termed coxa recta and coxa rotunda, characterized by low versus high concavity of the head-neck junction. Concavity is a measure of the sphericity of the femoral head as it meets the femoral neck that can be quantified by angular measurements.

[Shoulder surgery using only regional anaesthesia].

Effective intra-operative anaesthesia and peri-operative analgesia are important aspects of patient care in orthopaedic surgery. The interscalene regional anaesthetic block technique, performed with the patient lying in a lateral decubitus position, is new for arthroscopic shoulder surgery conducted in the Netherlands. The combination of the interscalene block (without general anaesthesia) and the lateral decubitus position results in better peri-operative conditions for the patient.

SUSHI: the Super Simple Hip score for younger patients.

We describe the development of a simple patient-based score for young patients with hip problems which concentrates on activities that are difficult for someone with a hip problem and includes an activity rating scale that measures the highest level of physical activity reached during the past year. We compared the super simple hip score (SUSHI) with the more extensive hip osteoarthritis outcome score (HOOS) and evaluated the validity, sensitivity to change and floor and ceiling effects of the SUSHI score. We found that the SUSHI score is an adequate score to measure hip problems and that this score was preferred to the HOOS score by patients.

A method to identify talent: visual search and locomotion behavior in young football players.

The present study examined differences in visual search and locomotor behavior among a group of skilled 10-12 year-old football players. The participants watched video clips of a 4-to-4 position game, presented on a large screen. The participants were asked to take part in the game by choosing the best position for the reception of the ball passed by one of the players in the clip.

Planning of an interceptive movement in children.

In the present study, we examined the spatio-temporal organization of the walking and reaching behaviour during an interception task in younger (6-9 years old) and older (10-13 years old) children. To this end, eighteen children had to walk towards an interception point to grasp a moving ball under three visual manipulation conditions. Walking and reaching behaviour were analysed during a condition allowing full vision of the ball trajectory and during two conditions in which vision towards the ball was partly occluded (enhanced planning requirement).
