Pediatric + fracture + remodeling

Pediatric panfacial trauma is a rare occurrence with poorly understood implications for the growing child. Treatment algorithms largely mirror adult panfacial protocols with notable exceptions including augmented healing and remodeling capacities that favor nonoperative management, limited exposure to avoid disruption of osseous suture and synchondroses growth centers, and creative fracture fixation techniques in the setting of an immature craniomaxillofacial skeleton. The following article provides a review of our institutional philosophy in the management of these challenges injuries with important anatomic, epidemiologic, examination, sequencing, and postoperative considerations...

BACKGROUND: Ogden type IV tibial tuberosity fractures, defined as a type of fracture with posterior-inferior metaphyseal extension (Salter-Harris type II variant), are uncommon but challenging pediatric fractures. The purpose of this study was to investigate the clinical and radiological presentation and associated surgical outcomes. METHODS: Ten previously healthy patients who had been surgically treated at the authors' institution between 2015 and 2018 with at least 2 years of postoperative follow-up were included...

We assessed the radiological and functional results of pediatric both-bone forearm diaphyseal fractures treated using elastic stable intramedullary nails (ESINs), as well as factors affecting the results. In total, 36 patients (33 males and three females; mean age, 11.6 years) were included. The mean follow-up time was 41.5 (18-96) months. Patient demographic characteristics and the details of the surgical techniques were analyzed retrospectively. In addition to standard radiographic evaluations, the ratio between the nail diameter and medullary canal diameter (ND/MCD) was measured, as well as the maximal radial bowing...

A 13-year-old girl presented with an apparent classic osteochondroma. Because she was skeletally immature, the decision was made to observe the lesion. She returned to the clinic at age 17 for unrelated reasons and was noted to no longer have the palpable mass. Magnetic resonance imaging confirmed resolution of the osteochondroma. The age range of this case fits with reported cases of childhood osteochondromas. The mechanism of resolution has been theorized to be incorporation of the lesion back into the bone during remodeling, fractures, or pseudoaneurysms...

Introduction  It is widely believed that fractures in children have excellent clinical outcomes due to their capacity to remodel. There are, however, certain fractures that require careful management to avoid long-lasting functional impairment. Functional outcomes following hand fractures in children are poorly studied. Materials and Methods  We performed a retrospective cohort study of consecutive children and adolescents who had operative treatment for metacarpal and phalangeal fractures (2008-2018)...

BACKGROUND: Children with a tibial shaft fracture often present with valgus malalignment, even when anatomical reduction had been achieved at the fracture site. Pediatric bony structure has more elastic bones than that of adults, it can cause bowing deformity. Therefore, we evaluated pediatric tibial shaft fracture for the presence of bowing deformity, associated risk factors, and its clinical significance. HYPOTHESIS: There is an overlooked bowing deformity in pediatric tibial shaft fracture...

The epiphyses at the medial and lateral ends of the clavicle are small, ossify relatively late, and may not fuse until early adulthood. Because of this unique anatomy, pediatric and young adult injuries that involve the clavicle often differ from the patterns typically seen in older adults. Clavicular trauma that affects the acromioclavicular joint laterally or sternoclavicular joint medially often results in a physeal fracture and as such, can go unrecognized or be mistaken for a joint dislocation. Radiographic assessment is challenging, particularly when the epiphysis is not yet ossified...

(1) Background: Trampoline fractures (proximal tibia fracture with positive anterior tilt) are increasing. This study represents the first attempt to determine the extent of remodeling in these fractures after conservative treatment (2) Methods: This Swiss prospective multicenter study included children aged 2 to 5 years with a trampoline fracture who were radiologically examined on the day of the accident and after one year. In addition, the anterior tilt angle was compared between the injured and unaffected tibia...

BACKGROUND: Bony remodeling of displaced clavicle fractures in adolescents remains poorly understood. PURPOSE: To evaluate and quantify clavicle remodeling in a large population of adolescents with completely displaced fractures, which were treated nonoperatively, to better understand the factors that may influence this process. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients were identified from the databases of a multicenter study group investigating the functional outcomes of adolescent clavicle fractures...

Diaphyseal humerus fractures in the pediatric population have dynamic treatment strategies that depend on injury pattern, mechanism, patient skeletal maturity, and size. Treatment strategies include closed reduction with various immobilization techniques, flexible nails, uniplanar or multiplanar external fixation, or plate osteosynthesis. Accepted parameters for sagittal and coronal alignment vary based on age and potential for remodeling, and the multiplanar motion of the shoulder joint can accommodate for greater variations in alignment than many other long bone fractures...

INTRODUCTION: Malunion of intra-articular fracture of the elbow in children is uncommon and may be difficult to treat. Intra-articular corrective osteotomies are still not commonly performed in children, and the main reason is the concern regarding the risk of osteonecrosis. We present a case of extra-articular corrective osteotomy for malunion after open reduction and internal fixation for fracture dislocation of the elbow. CASE REPORT: An 8-year-old boy was injured by a fall and he underwent an operation the day after the injury with diagnosis of lateral condyle fracture of the right humerus...

BACKGROUND: Intramedullary nailing using Kirschner wires in pediatric diaphyseal forearm fractures is often performed as a less invasive treatment than plate fixation, but it remains controversial whether the tips of Kirschner wires are buried or exposed. The purpose of this study was to investigate the relationship between whether the tips are buried or exposed and complications, especially of refracture. METHODS: Data of 405 patients under 16 years who underwent surgical treatment for diaphyseal forearm fractures in our 11 hospitals between 2010 and 2020 were collected...

OBJECTIVE: To assess the validity and safety of kyphoplasty combined with short-term posterior instrumentation to treat children with vertebrae plana due to eosinophilic granuloma (EG). PATIENTS AND METHODS: Clinical data of EG patients, who received kyphoplasty and short-term instrumentation from March 2019 to March 2020, were retrospectively reviewed. The recovery of diseased vertebrae was assessed and compared with historical case data. RESULTS: Nine patients with EG had received kyphoplasty and short-term posterior instrumentation...

OBJECTIVE: When there is a complete slippage of facet joints of C1 over C2 such that there is no contact between the articulating surfaces of C1 and C2, the condition is known as atlantoaxial spondyloptosis (AAS). AAS represents an extremely rare manifestation of atlantoaxial instability. This study was performed to highlight the presentation, radiological features, and management of unilateral AAS in pediatric patients. MATERIAL AND METHODS: We retrospectively identified four pediatric patients with AAS from our hospital records in the last 6 years (2014-2019)...

Fracture geometry, particularly a jagged bone spike, can present a physical barrier in closed reduction of pediatric distal radius-ulna fractures. When closed reduction of the fracture is not possible, accepting an incomplete reduction and hoping for remodeling, or open reduction, which poses a greater risk for infection and potential physeal injury, are alternative treatment options. The objective of this study was to describe a technique, coined as Percutaneous Skeletal Traction Aided Reduction (P_STAR), for reducing these fractures, thereby eliminating the acceptance of an incomplete reduction and the risks associated with open reduction...

Pediatric foot and ankle fractures are common in athletic participation. Treatment of pediatric sports trauma must take into account the unique challenges this population presents, and aim to minimize long-term complications. Given the excellent remodeling potential of pediatric bone, conservative treatment can often be used. However, a thorough understanding of physeal anatomy, fracture patterns, and biomechanics is needed to guide treatment choice and determine when surgical intervention is warranted.

BACKGROUND: The purpose of this study was to retrospectively evaluate and follow up a conservative treatment approach with functional orthodontic appliances for the management of mandibular condyle fractures in children and adolescent patients. METHODS: Between 2020 and 2022, the treatment records of patients with mandibular condyle fractures receiving a functional orthodontic treatment (FOT) were evaluated. In addition to the clinical and functional findings, magnetic resonance images of the mandibular condyles and surrounding structures were assessed...

PURPOSE: Minimally displaced pediatric proximal humerus fractures can be reliably managed non-operatively; however, there is considerable debate regarding the appropriate management of severely displaced proximal humerus fractures, particularly in older children and adolescents with limited remodeling potential. The purpose of this study was to perform a systematic review to answer the questions: "What are the functional and quality-of-life outcomes of pediatric proximal humerus fractures?" and "What factors have been associated with a poorer outcome?" METHODS: A review of Medline and Embase was performed on 4 July 2021 using search terms relevant to proximal humerus fractures, surgery, non-operative management, pediatrics, and outcomes...

This study aims to investigate the brain gray matter volume (GMV) alterations of pediatric complete thoracolumbar spinal cord injury (SCI) without fracture or dislocation (SCIWOFD) using voxel-based morphometry (VBM) analysis and assess the sensitive neuroimaging biomarkers that may be surrogate targets to enhance brain plasticity. A total of 52 pediatric subjects (age range, 6-12 years), including 25 pediatric SCIWOFD patients and 27 typically developing (TD) children were recruited. An independent two-sample t test was performed to assess between-group differences of brain GMV...

BACKGROUND: Historically most pediatric pelvic fractures were treated non-operatively because of the presumed potential of the pediatric pelvis to remodel and the subsequent increased fracture stability. Currently a wide variety of classifications in pediatric pelvic fractures is used to assess fracture stability and guide treatment, yet none have proven to be ideal since the structural behavior of the pediatric pelvis differs greatly from the adult pelvis. The aim of this review is to critically appraise the use of these different classification systems, fracture (in)stability, the treatment of pediatric pelvic fractures and how it reflects on long-term complications such as pelvic asymmetry and functional outcome...
