PURPOSE: Trochlear dysplasia is one of the main risk factors for recurrent patellar dislocation. The Dejour classification identifies four categories that can be used to classify trochlear dysplasia. The purpose of this study is to evaluate the inter- and intraobserver reliability of the Dejour classification for trochlear dysplasia. The hypothesis was that both intra- and interobserver reliability would be at least moderate. METHODS: This is a cross-sectional, reliability study...

INTRODUCTION: Bone growth is a fascinating process, primarily due to its complexity. Equally engaging is the history of its study, which, however, remains unknown to most anatomists and surgeons. MATERIALS AND METHODS: A literature search was performed in original publications and historical sources. RESULTS: The early history of bone growth study may be divided into two periods. Firstly, the experimental one, between 1722 and 1847, which consisted in the study of bone growth by the drilling of benchmark holes into the diaphysis, and examination of growing bones in madder-fed animals...

OBJECTIVE: To evaluate the diagnostic accuracy of ultrasound secondary signs of fractures in pediatric patients aged 5-15 y presenting to the emergency department with a clinically non-deformed distal forearm injury. METHODS: This diagnostic study was conducted in South East Queensland, Australia. Emergency clinicians performed point-of-care ultrasound on eligible patients and recorded secondary signs of fractures (pronator quadratus hematoma [PQH] sign, periosteal hematoma, visible angulation) or physeal fractures (fracture-to-physis distance [FPD], physis alteration)...

Amniotic band syndrome (ABS) constriction rings in the lower limb are common. Despite this, there is insufficient literature on anatomical abnormalities in the knee joints of children with ABS. There is an increasing incidence of paediatric anterior cruciate ligament (ACL) injuries recently. ACL reconstruction in this population has an extra dilemma of sparing the physis to prevent growth disturbances. Treating both these conditions simultaneously is a challenge that is rarely encountered. In our literature review, we found no case such as this...

Modern medicine tends to privilege disciplines promising "objective" laws governing body parts (from molecules to organs). Studies on a person's illness and disability are (apparently) confined to "subjectivity." The Specialty of Physical and Rehabilitation Medicine is often regarded as a humanitarian approach, belonging at best to the family of "soft," "qualitative," or "quasi-experimental" sciences. This specialty often claims specificity by labelling itself as "functional" and "holistic." However, it is shown here that the former term is acceptable, yet redundant, and the second misleading...

BACKGROUND: Simple bone cysts (SBC) are benign tumor-like bone lesions typically identified in children. While SBC may lead to growth disturbances or growth arrest, such cases are uncommon. The mechanisms behind these observations remain unclear. Additionally, research on the etiology of SBC remains inconclusive, and there has been no consensus on the appropriate timing and methodology for treatment. CASE SUMMARY: Here, we present our experience in the successful surgical management of a 10-year-old girl with SBC, who presented with a pathological fracture complicated by malunion of the displaced fracture, varus deformity, and limb length discrepancy...

BACKGROUND: Septic necrosis of the femoral head and neck in children represents a challenging problem. Several reconstructive techniques have been described but with disappointing long-term results. Vascularized epiphyseal transfer utilizing the proximal fibula have been successfully used for reconstruction of the proximal humerus and distal radius and only scarcely used for hip reconstruction. This cohort represents the largest reported series of epiphyseal transfer for hip reconstruction following septic necrosis in children...

Khalid A Bakarman
The purpose of this review is to increase awareness about the evolution and development of current trends in the diagnosis and treatment of aneurysmal bone cysts (ABCs). ABCs are benign, but locally aggressive bone tumors that mainly affect children. ABCs comprise 1% of all primary bone tumors and occur most frequently during the first two decades of life. The diagnosis is made using a variety of imaging modalities and has the characteristic features of an expansile, radiolucent lesion that is often seen in the metaphyseal region of the bone and has fluid-fluid levels that are apparent on MRI...

INTRODUCTION: Distal pole of patella avulsion fracture with tibial tuberosity avulsion has been frequently reported as a bifocal patellar tendon injury. However, an osteochondral lateral patella facet fracture with a longitudinal split in the patella tendon in addition to these avulsion fractures has never been documented previously. Hence, we now report this trifocal patellar tendon injury. CASE REPORT: An adolescent with a trifocal patella tendon injury underwent a fixation with a combination of transosseous pull- through sutures, suture tape, and knotless anchor...

Zn-ion hybrid supercapacitors (ZHCs) combining merits of battery-type and capacitive electrodes are considered to be a prospective candidate in energy storage systems. Tailor-made carbon cathodes with high zincophilicity and abundant physi/chemisorption sites are critical but it remains a great challenge to achieve both features by a sustainable means. Herein, a hydrogen-bonding interaction-guided self-assembly strategy is presented to prepare iodine-doped carbon nanocages without templates for boosting zinc-ion storage by nucleophilicity...

Fractures and dislocations of the sternoclavicular joint (SCJ) are uncommon, accounting for <5% of all shoulder girdle injuries. They are relatively more common in the pediatric population than in the adult population and can often present concurrently as a posteriorly displaced medial clavicular dislocation with a fracture through the unfused physis. It is especially important to recognize this injury, because its management and potential sequelae are very different from those for fractures of the clavicle shaft...

BACKGROUND: Anterior cruciate ligament (ACL) tears in skeletally immature patients are increasingly common. Evidence comparing the outcomes of all-epiphyseal versus trans-epiphyseal ACL reconstruction in skeletally immature patients is limited, and the current literature could benefit from a comprehensive systematic review. The present study compared all-epiphyseal versus trans-epiphyseal ACL reconstruction in skeletally immature patients. The outcomes of interest were to compare joint laxity, patient-reported outcome measures (PROMs), return to sport, and complications...

Ionic liquids (ILs) are a class of salts existing in the liquid state below 100 °C, possessing low volatility, high thermal stability as well as many highly attractive solvent and electrochemical capabilities, etc. , making them highly tunable for a great variety of applications, such as lubricants, electrolytes, and soft functional materials. In many applications, ILs are first either physi- or chemisorbed on a solid surface to successively create more functional materials. The functions of ILs at solid surfaces can differ considerably from those of bulk ILs, mainly due to distinct interfacial layers with tunable structures resulting in new ionic liquid interface layer properties and enhanced performance...

We have encountered consecutive children/adolescents with a volar Barton fracture (VBF) pattern without involving the physis. These were managed by buttress plating; thus, we would like to report the radiological and clinical outcomes through retrospective case series and suggest the revisiting of the 'VBF category' in this population. We screened children/adolescents with a diagnosis of trauma to the bony structures in the wrist from 2008 to 2019. Of these patients, 16 who met our inclusion/exclusion criteria were investigated...

Diffusion tensor imaging of physis and metaphysis can be used as a biomarker to predict height change in the pediatric population. Current application of this technique requires manual segmentation of the physis which is time-consuming and introduces interobserver variability. UNET Transformers (UNETR) can be used for automatic segmentation to optimize workflow. Three hundred and eighty-five DTI scans from 191 subjects with mean age of 12.6 years ± 2.01 years were retrospectively used for training and validation...
