Background: Transphyseal hematogenous osteomyelitis (THO) is a common infectious condition, being present in 25% of patients with hematogenous osteomyelitis. A large proportion of pediatric hematogenous osteomyelitis infections can spread through the growth cartilage and therefore may be potentially responsible for growth disorders, leading to limb-length discrepancy or angular deformities. The purpose of the present study was to identify both the prevalence of complications caused by transphyseal osteomyelitis and factors influencing their occurrence.

Article Synopsis
  • The study evaluates the effectiveness of rasterstereography versus low-dose, biplanar spine radiography in measuring thoracic kyphosis angles in patients with Scheuermann's disease.
  • The research involved 52 patients who underwent both imaging techniques on the same day, revealing strong correlations in TK angle measurements.
  • Results showed that rasterstereography can reliably assess TK angles, potentially decreasing the need for radiographic scans and reducing patients' exposure to radiation.

Purpose: Tibial torsion disorders may lead to abnormal gait, frequently leading to a consultation with a pediatric orthopedic surgeon. The present study evaluated an alternative method for assessing tibial torsion on computerized tomography (CT) images that considers the tibial distal axis to be equivalent to the geometric axis of the tibiotalar joint.

Methods: One hundred CT scans were reviewed retrospectively, and four measurements were taken: proximal transtibial angle (PTTA), posterior margin tibial plateau angle (PMTPA), intermalleolar angle (IMA), and talar angle (TA).

The shear fractures of the capitellum are rare fractures in the pediatric population. Their diagnosis is challenging because of the high cartilaginous component of the growing elbow, requiring a high level of clinical suspicion especially in the case of small osteochondral or chondral fragments. The literature on capitellar shear fractures is mainly represented by case reports, which provides a patchy view of the topic.

Pediatric septic arthritis of the hip (SAH) in children is a severe pathology, requiring prompt diagnosis and treatment to avoid destructive sequelae of the joint. Its diagnosis can be challenging, however, due to its spectrum of manifestations and differential diagnosis. Last century, multiple research teams studied the curves of systemic inflammation markers to aid the differential diagnosis.

The posterior minimally invasive spine surgery (MISS) approach-or the paraspinal muscle approach-for posterior spinal fusion and segmental instrumentation in adolescent idiopathic scoliosis (AIS) was first reported in 2011. It is less invasive than the traditionally used open posterior midline approach, which is associated with significant morbidity, including denervation of the paraspinal muscles, significant blood loss, and a large midline skin incision. The literature suggests that the MISS approach, though technically challenging and with a longer operative time, provides similar levels of deformity correction, lower intraoperative blood loss, shorter hospital stays, better pain outcomes, and a faster return to sports than the open posterior midline approach.

Primary spinal infection (PSI) is a generic term covering a heterogeneous group of infections that can affect the vertebral body, intervertebral disks, the content of the medullary cavity, and adjacent paraspinal tissues. Patients' characteristics can vary significantly, notably according to their age, and some of these characteristics undoubtedly play a primordial role in the occurrence of a PSI and in the type of offending pathogen. Before approaching the subject of laboratory diagnostics, it is essential to define the characteristics of the patient and their infection, which can then guide the physician toward specific diagnostic approaches.

Article Synopsis
  • - Acute spinal subdural haematoma (ASSH) is a rare condition that can arise during spinal surgery, even in patients without known bleeding disorders, as demonstrated in a reported case involving a child undergoing surgery for congenital scoliosis.
  • - The case emphasizes the importance of neuromonitoring during surgeries like spinal fusions to detect any complications quickly, allowing for timely interventions to improve outcomes.
  • - ASSH is usually linked with anticoagulation therapy or coagulopathy, but this specific instance highlights the need to understand the aetiology behind such occurrences and improve management protocols for similar cases.

Introduction: Osteoarticular infections (OAIs) constitute serious paediatric conditions that may cause severe complications. Identifying the causative organism is one of the mainstays of the care process, since its detection will confirm the diagnosis, enable adjustments to antibiotic therapy and thus optimize outcomes. Two bacteria account for the majority of OAIs before 16 years of age: Staphylococcus aureus is known for affecting the older child, whereas Kingella kingae affects infants and children younger than 4 years old.

The treatment paradigm for osteoarticular infections (OAIs) has changed drastically over the past 80 years, from the advent of penicillin to the use of broad-spectrum antibiotics. Before these drugs, surgery was the only available treatment for OAIs; today, antibiotic therapy is considered the primary response to them. As a result, surgical treatment of OAIs is thus far more rarely indicated, sometimes even considered outdated and obsolete.
