NEW PATHOPHYSIOLOGICAL INSIGHTS: Based on improved knowledge of the vascular supply of the proximal femur, a safe surgical dislocation of the hip joint was established allowing direct insights to the pathomorphological malfunctioning of the joint. One insight was that slipped capital femoral epiphysis (SCFE) impingement leads to substantial damage of the chondrolabral rim area, even in the presence of minor slips. A further surgical development was the extended retinacular flap allowing for correction of the deformity with calculable risk for iatrogenic necrosis...

PURPOSE: Slipped capital femoral epiphysis (SCFE) is a deformity of the proximal femur secondary to widened and unstable physis. In stabilising the slip, gold standard treatments stop growth and involve premature physeal closure, which prevents the remodelling of the acquired deformity and creates a leg length discrepancy that may be significant in younger patients. METHODS: We measured the impact of placing threaded screws across the proximal femoral physis by measuring the centre-trochanteric distance (CTD) and articulo-trochanteric distance (ATD) in participants with or without prophylactic fixation...

PURPOSE: The purpose of our study was to investigate the histological, histochemical and ultrastructural aspects of the proximal femoral growth plate in slipped capital femoral epiphysis (SCFE). METHODS: Eight core biopsies of the proximal femoral growth plate were performed during in situ epiphysiodesis in patients with SCFE that was at the pre-slipping stage in two cases and at the mild slipping stage (Southwick angle < 30°) in six cases. After fixation, the specimens were processed for either histological or histochemical or ultrastructural studies...

Slipped capital femoral epiphysis (SCFE) remains the most common adolescent hip disorder. Most cases present with stable slips, and in situ fixation is the most commonly adopted treatment worldwide. The introduction of the concept of femoroacetabular impingement and subsequent studies have revealed SCFE-related hip impingement to be a significant pre-arthritic condition, and the previously suggested remodeling of the proximal femur after in situ fixation has been called into question. Complex proximal femoral osteotomies and more recently intra-articular procedures via surgical hip dislocation have been employed...

Obstetric traumatic separation of the distal humeral epiphysis is a very uncommon injury, which presents a diagnostic challenge. These case serials reviewed the functional outcomes of 5 patients who had sustained a fracture-separation of the distal humeral epiphysis at birth. The diagnosis was made at a mean time of 40.8 h after delivery. All the patients were treated with gentle close manipulation, reduction under fluoroscopy and above-elbow cast application. After discharge, the patients were followed up for a mean of 30 months...

Injury to the growth plate is associated with growth disturbances, most notably premature cessation of growth. The goal of this study was to identify spatial changes in the structure and composition of the growth plate in response to injury to provide a foundation for developing therapies that minimize the consequences for skeletal development. We used contrast-enhanced micro-computed tomography (CECT) and histological analyses of a murine model of growth plate injury to quantify changes in the cartilaginous and osseous tissue of the growth plate...

Microwave irradiation (MW) is an effective technique in heating and pyrolysis. This study compared the properties of peanut shell-biochars produced using MW and muffle furnace (FN). At the same pyrolysis temperature, MW biochars preserved more biomass (as indicated by their higher yields and higher abundance of functional groups) and possessed larger surface areas due to the high abundance of micropores. MW biochars generally exhibited higher adsorption of carbamazepine (CBZ) and bisphenol A (BPA) than FN biochars...

Fractures of the proximal tibial epiphysis are rare, representing less than 3% of all epiphyseal and 1% of all physeal injuries in adolescents. Bilateral injuries are extremely rare. The specific anatomical and histological features of the proximal tibial epiphysis make it vulnerable to a specific fracture pattern that occurs when the tensile force of the quadriceps is greater than the fibrocartilaginous tissue underlying the tibial tuberosity. We report the first case to our knowledge of a 12-year-old boy who sustained simultaneous bilateral tibial avulsion fractures on the background of a previous conservatively managed unilateral tibial tuberosity avulsion fracture...

Slipped capital femoral epiphysis (SCFE) is a common hip disorder in older children and adolescents, classically with medial and posterior slippage of the proximal femoral epiphysis. However, valgus SCFE is a very rare entity, where the proximal femoral epiphysis slips laterally and posteriorly. To our knowledge, valgus SCFE with magnetic resonance imaging (MRI) features of contralateral pre-slip has not yet been reported. We present a case of a 9 year old girl with symptomatic valgus SCFE on the left and asymptomatic contralateral pre-slip on the right with concurrent radiographic, sonographic, and MRI findings...

CASE REPORT: A 4-month-old female intact American Pit Bull Terrier was presented for right pelvic limb lameness 1 day after the dog had been hit by an all-terrain vehicle. Orthogonal radiographs of the right stifle revealed a Salter-Harris type IV fracture through the proximal tibial physis extending caudodistally through the proximal tibial metaphysis. The distal tibia was markedly displaced cranially, laterally and proximally, resulting in complete overriding of the fracture segments...

BACKGROUND: Neurofibromatosis type 1 is a hereditary disease that can lead to pseudoarthrosis of various long bones. Rarely, pseudoarthrosis affects the forearm, and to the best of our knowledge, this is the first reported case of pseudarthrosis of the distal radius treated by this unique method. METHODS: We present a case of a 7-year-old male who underwent multiple operations to treat pseudoarthrosis of the distal radius. RESULTS: After failed conservative and operative fixation augmented with autologous iliac crest bone grafting, the patient underwent a successful double-barrel vascularized free fibula graft while preserving the physis of the distal radius...

BACKGROUND: Slipped capital femoral epiphysis (SCFE), a fracture through the physis with resultant slip of the epiphysis, is the most common hip abnormality in adolescents and is a major cause of early osteoarthritis. Plain radiograph is the initial modality used to evaluate patients with painful hip joints. Ultrasonography and magnetic resonance imaging (MRI), which do not involve radiation exposure, have also been used. This case report supports the view that ultrasound can be used as an initial, cost-effective and radiation-free modality for the evaluation of suspected SCFE...

INTRODUCTION: Tillaux Fractures are an infrequent type of fracture that occurs in teenagers. The mechanism is an external rotation that causes stress on the anterior tibiofibular ligament, which displace the distal tibial physis fragment. METHODS: 6 patients (5 girls and one boy), with an age between 12-14 years, who had Tillaux fractures with a displacement more than 2 mm; were treated by orthopedic reduction and fixation with a screw. RESULTS: After surgery patients underwent cast immovilization for 4 to 6 weeks; starting then progressive partial bear-weight...

OBJECTIVE: X-linked hypophosphatemic rickets (XLH) is the most common form of inheritable rickets. Rickets treatment is monitored by assessing alkaline phosphatase (ALP) levels, clinical features, and radiographs. Our objectives were to describe the magnetic resonance imaging (MRI) features of XLH and to assess correlations with disease activity. STUDY DESIGN: Twenty-seven XLH patients (median age 9.2 years) were included in this prospective single-center observational study...

OBJECTIVES: Bone bridge formation occurs after physeal lesions and can lead to growth arrest if not reversed. Previous investigations on the underlying mechanisms of this formation used histological methods. Therefore, this study aimed to apply a minimally invasive method using dynamic contrast-enhanced MRI (DCE-MRI). MATERIALS AND METHODS: Changes in functional parameters related to the microvessel system were assessed in a longitudinal study of a cohort of an animal model applying a reference region model...

Cam morphology of the proximal femur is an abnormal contour of the femoral head-neck junction present in approximately 15% to 25% of the asymptomatic population, predominantly in males. Alpha angle and femoral head-neck offset ratio are 2 objective measurement tools that define cam morphology. Both primary (idiopathic) and secondary cam deformity develops through distinct mechanisms. The cause of primary (idiopathic) cam morphology remains incompletely understood. Mounting evidence suggests that idiopathic cam morphology develops during adolescence through alterations in the capital femoral epiphysis in response to participation in vigorous sporting activity...

PURPOSE: Ramp lesions are common in ACL deficient knees. Their diagnosis is difficult and, therefore, they may be underestimated. So far, no study analyzed their prevalence in a pediatric population. The diagnosis of these Ramp lesions is of major clinical relevance because of a frequent misestimating and technic difficulties. Ramp lesions might be associated with residual knee pain and instability after ACL reconstruction. The aim of this study was to evaluate the prevalence of ramp lesions explored through a systematic intercondylar and posteromedial arthroscopic approach during an ACL reconstruction in a pediatric and adolescent population...
