GUIDANCE study: guided growth of the proximal femur to prevent further hip migration in patients with cerebral palsy-study protocol for a multicentre randomised controlled trial.

Introduction: Up to one-third of patients with cerebral palsy (CP) develop hip migration. Current standard care for early hip migration is bilateral adductor-psoas tenotomy; however, the failure rate is relatively high with 34%-74% of patients with CP requiring secondary hip surgery. Using temporary medial hemiepiphysiodesis of the proximal femur (TMH-PF), the morphology of the hip can be changed.

Do Adductor Tenotomies Prevent Progressive Migration in Children with Cerebral Palsy?: A Systematic Review.

Background: Up to one-third of children with cerebral palsy (CP) develop migration of the hip, and the risk increases with a higher Gross Motor Function Classification System (GMFCS). In progressive hip migration in young children, adductor tenotomy is an accepted treatment option to delay or prevent progressive hip migration. However, there is quite a large variability in reported results.

Timely Surgical Intervention Leads to Better Sustained Coverage after Reconstructive Hip Surgery in Patients with Cerebral Palsy.

Background: In up to 45-90% of non-ambulatory patients with cerebral palsy (CP), progressive hip migration can be observed. The goal of this study was to determine whether the implementation of a national hip surveillance guideline affected the outcome of hip reconstructions.

Methods: We reviewed 48 primary hip reconstructions at a median follow-up of 4.

Effect of tranexamic acid on intraoperative blood loss in pediatric osteotomies around the hip: Study protocol for a double-blind randomized placebo-controlled trial.

Background: Proximal femoral and/or pelvic osteotomies (PFPOs) can be indicated for a multitude of hip pathologies in (often asymptomatic) children, to prevent future hip problems. These procedures can result in significant blood loss. Tranexamic acid (TXA) is an antifibrinolytic agent routinely administered in adult trauma and joint reconstruction surgery to reduce blood loss.

Strategies to optimize the information provision for parents of children with developmental dysplasia of the hip.

Aims: The aim of this study was to identify the information topics that should be addressed according to the parents of children with developmental dysplasia of the hip (DDH) in the diagnostic and treatment phase during the first year of life. Second, we explored parental recommendations to further optimize the information provision in DDH care.

Methods: A qualitative study with semi-structured interviews was conducted between September and December 2020.

The Importance of Monitoring and Factors That May Influence Leg Length Difference in Developmental Dysplasia of the Hip.

Unlabelled: In unilateral Developmental Dysplasia of the Hip (DDH), avascular necrosis (AVN), femoral or pelvic osteotomy, and residual dysplasia causing subluxation of the proximal femur may influence Leg Length Discrepancy (LLD). This can lead to gait compensation, pelvic obliquity, and spinal curvature. The aim of this study is to determine the prevalence of LLD, establish which limb segment contributes to the discrepancy, describe how AVN influences LLD, and ascertain variables that may influence the need for LLD corrective procedures.

Parental experiences of children with developmental dysplasia of the hip: a qualitative study.

Objective: The aim of this qualitative study was to explore the experiences of Dutch parents of children with developmental dysplasia of the hip (DDH), treated with a Pavlik harness, during the diagnostic and treatment process in the first year of life.

Design: A qualitative study by means of semistructured interviews was conducted between September and December 2020. Qualitative content analysis was applied to code, categorise and thematise data.

Tension-band Plating for Leg-length Discrepancy Correction.

Aim: Dual tension-band plates are used for temporary epiphysiodesis and longitudinal guided growth. The study aim was to assess rate of correction, to identify development of femoral and tibial intra-articular deformity during correction and to document resumption of growth after plate removal.

Materials And Methods: A retrospective study of 34 consecutive patients treated with dual tension-band plates between 2012 and 2020 was performed.

The Development of Leg Length Difference and Influence on Persistent Dysplasia in Patients with Developmental Dysplasia of the Hip.

Introduction: Leg-length difference (LLD) is common in patients with developmental dysplasia of the hip (DDH). LLD of > 1 cm at skeletal maturity is reported in > 40% of patients, with the majority related to ipsilateral overgrowth. A longer DDH leg might lead to excessive mechanical loading at the acetabular margin, resulting in compromised acetabular development.

Leg length discrepancy in patients with Perthes' disease : a note of caution for the arthroplasty surgeon.

Aims: Perthes' disease (PD) often results in femoral head deformity and leg length discrepancy (LLD). Our objective was to analyze femoral morphology in PD patients at skeletal maturity to assess where the LLD originates, and evaluate the effect of contralateral epiphysiodesis for length equalization on proximal and subtrochanteric femoral lengths.

Methods: All patients treated for PD in our institution between January 2013 and June 2020 were reviewed retrospectively.

The influence of expectation modification in knee arthroplasty on satisfaction of patients: a randomized controlled trial.

Aims: Meeting preoperative expectations is known to be of major influence on postoperative satisfaction after total knee arthroplasty (TKA). Improved management of expectation, resulting in more realistic expectations can potentially lead to higher postoperative satisfaction. The objective of this study was to assess the effect of an additional preoperative education module, addressing realistic expectations for long-term functional recovery, on postoperative satisfaction and expectation fulfilment.

Timing of Repeat Ultrasound Examination in Treatment of Stable Developmental Dysplasia of the Hip.

Background: Worldwide a wide variation exists in duration of Pavlik harness treatment for infants up to 6 months with stable developmental dysplasia of the hip (DDH). The purpose of this study was to evaluate whether shortening the time to first routine follow-up ultrasound after initiation of Pavlik harness treatment would reduce treatment duration and whether this influenced radiologic outcome at 1 year of age. Furthermore, predictors of higher acetabular index (AI) at 1 year of age were investigated.

Interventions and measurements of highly reliable/resilient organization implementations: A literature review.

Since the inception of High Reliability Theory in 1981, researchers and practitioners have theorized about the questions, "How do you know if you're an HRO, and how do you validate it?" Evidence now exists that organizations seeking high reliability and resilience have moved away from the theoretical phase, and into the application phase where organizations adopt the HRO hallmarks plus culture as operational targets and create interventions to effect change. The evidence of high reliability operations in organizations is key for validating that HRO is implementable and is also beneficial. After collecting over 1400 artifacts, we found 34 scholarly efforts published which purposefully targeted implementation measures toward achieving an HRO state and measured the outcomes.

[Touched by an angel].

The case of a 4-year-old boy with a symmetrical deformity of the 5th fingers is presented. Radiographs showed dysplastic development of the middle phalanx resembling the shape of ''Christmas tree angels''. A finding typical for Angel-shaped phalango-epiphyseal dysplasia (ASPED).

Paediatric Posttraumatic Cyst-Like Lesions: A Report of Two Cases and Review of the Literature.

Posttraumatic cyst-like lesions are a rare finding after greenstick fractures in children. These asymptomatic, cystic lesions become radiologically apparent 2-4 months after the initial trauma. Conventional radiographs typically show nonexpansile, well-circumscribed lesions in the cortex, proximal to the fracture site.

Development of Preoperative Prediction Models for Pain and Functional Outcome After Total Knee Arthroplasty Using The Dutch Arthroplasty Register Data.

Background: One of the main determinants of treatment satisfaction after total knee arthroplasty (TKA) is the fulfillment of preoperative expectations. For optimal expectation management, it is useful to accurately predict the treatment result. Multiple patient factors registered in the Dutch Arthroplasty Register (LROI) can potentially be utilized to estimate the most likely treatment result.

Outcome Expectations of Total Knee Arthroplasty Patients: The Influence of Demographic Factors, Pain, Personality Traits, Physical and Psychological Status.

Unfulfilled preoperative expectations have a strong influence on the outcome after total knee arthroplasty (TKA). More insight into determinants of the level of expectations is useful in identifying patients at risk for having expectations of the treatment result that are too high or too low. This information can be used in optimizing preoperative expectation management.

Measurement properties of the OARSI core set of performance-based measures for hip osteoarthritis: a prospective cohort study on reliability, construct validity and responsiveness in 90 hip osteo-arthritis patients.

Background and purpose - Improvement of physical function is one of the main treatment goals in severe hip osteoarthritis (OA) patients. The Osteoarthritis Research Society International (OARSI) has identified a core set of performance-based tests to assess the construct physical function: 30-s chair stand test (30-s CST), 4x10-meter fast-paced walk test (40 m FPWT), and a stair-climb test. Despite this recommendation, available evidence on the measurement properties is limited.

The EKSPECT study: the influence of Expectation modification in Knee arthroplasty on Satisfaction of PatiEnts: study protocol for a randomized Controlled Trial.

Background: One out of five patients is unsatisfied to some extent after total knee arthroplasty (TKA). Unmet expectations are the main driver of post-operative dissatisfaction. Improved pre-operative education on realistic expectations for long-term outcome after TKA potentially leads to higher post-operative satisfaction.

The OARSI core set of performance-based measures for knee osteoarthritis is reliable but not valid and responsive.

Purpose: The Osteoarthritis Research Society International has identified a core set of performance-based tests of physical function for use in people with knee osteoarthritis (OA). The core set consists of the 30-second chair stand test (30-s CST), 4 × 10 m fast-paced walk test (40 m FPWT) and a stair climb test. The aim of this study was to evaluate the reliability, validity and responsiveness of these performance-based measures to assess the ability to measure physical function in knee OA patients.

When is it safe to resume driving after total hip and total knee arthroplasty? a meta-analysis of literature on post-operative brake reaction times.

Aims: The aim of this study was to assess the current available evidence about when patients might resume driving after elective, primary total hip (THA) or total knee arthroplasty (TKA) undertaken for osteoarthritis (OA).

Materials And Methods: In February 2016, EMBASE, MEDLINE, Web of Science, Scopus, Cochrane, PubMed Publisher, CINAHL, EBSCO and Google Scholar were searched for clinical studies reporting on 'THA', 'TKA', 'car driving', 'reaction time' and 'brake response time'. Two researchers (CAV and JJT) independently screened the titles and abstracts for eligibility and assessed the risk of bias.

Total Knee Arthroplasty: What to Expect? A Survey of the Members of the Dutch Knee Society on Long-Term Recovery after Total Knee Arthroplasty.

The rate of satisfaction after total knee arthroplasty (TKA) is consistently reported around 80%, leaving one in five patients unsatisfied to some extent. Fulfillment of expectations is reported as the strongest predictor of treatment satisfaction. In this study, we aimed to evaluate what Dutch orthopedic surgeons assume are realistic expectations for recovery 1 year after TKA.

Infection after anterior spinal fusion for idiopathic scoliosis using the Cotrel-Dubousset-Hopf system: A clinical case series of three patients.

Background: Three patients with late-onset infection after multilevel instrumented anterior spinal fusion for idiopathic scoliosis, using the Cotrel-Dubousset-Hopf (CDH) system, are presented. The CDH-system is an anterior instrumentation with high biomechanical stability and rigidity, ensuring a stable primary fixation. Unlike after posterior spinal fusion, infection after anterior spinal fusion (ASF) for idiopathic scoliosis has rarely been reported.
