PURPOSE: Today, synthetic models have all but replaced animal and corpse models in examining damage to soft-tissues and skeletal structures by ballistic trauma. As, however, non-solid organs such as the lungs, have not been able to be replaced by a fully synthetic model we attempted to create such a model. MATERIAL AND METHODS: 20% ordnance gelatine was frothed with a household mixer and cooled to stable foam. Several of these foam blocks were then stuck together with liquid gelatine and placed between 10% gelatine blocks...

Young Hak Roh, Jung Ho Noh, Hyun Sik Gong, Goo Hyun Baek
Patients with low appendicular lean mass plus slow gait speed or weak grip strength are at risk for poor functional recovery after surgery for distal radius fracture, even when they have similar radiologic outcomes. INTRODUCTION: Loss of skeletal muscle mass and consequent loss in muscle function associate with aging, and this condition negatively impacts the activities of daily living and increases elderly individuals' frailty to falls. Thus, patients with low appendicular lean mass would show different functional recovery compared to those without this condition after surgery for distal radius fracture (DRF)...

Musculoskeletal manifestations in chronic kidney disease (CKD) are the result of a series of complex alterations in mineral metabolism, which has been defined as chronic kidney disease - mineral and bone-related disorder (CKD-MBD). Biochemical assessment and, at times, bone biopsy remains the mainstay of disease assessment, however, radiological imaging is an important adjunct in evaluating disease severity. This review aims to illustrate the radiological features of CKD-MBD, such as secondary hyperparathyroidism, osteomalacia, adynamic bone disease, osteopenia, and extra-skeletal calcifications...

Nowadays, surgery, radiotherapy and chemotherapy are the most frequently used modalities in the treatment of breast cancer. It is very well-known that some severe complications may result from after these treatments. Early and late complications of radiotherapy are well known. The complications of radiation therapy may be seen in (early) or after three months (late-delayed) of periods. These complications may be related with direct or indirect effect of radiation. The radiation fibrosis syndrome is a progressive fibrotic tissue sclerosis together with various clinical symptoms in the irradiation field...

BACKGROUND: Osteopetrosis is a rare hereditary metabolic bone disorder characterized by generalized skeletal sclerosis caused by a defect in bone resorption and remodelling. Infantile autosomal recessive osteopetrosis is one of three subtypes of osteopetrosis and the most severe form. The correct and early diagnosis of infantile osteopetrosis is important for management of complications and for future genetic counselling. Diagnosis is largely based on clinical and radiographic evaluation, confirmed by gene testing where applicable...

OBJECTIVE: There has been an increasing movement worldwide to create systematic screening and management procedures for atypical injury patterns in children with the hope of better detecting and evaluating nonaccidental trauma (NAT). A legitimate concern for any hospital considering implementation of a systematic evaluation process is the impact on already burdened hospital resources. We hypothesized that implementation of a guideline that uses red flags related to history, physical, or radiologic findings to trigger a standardized NAT evaluation of patients <4 years would not negatively affect resource utilization at our level II pediatric trauma center...

Finger fractures are the most common skeletal injuries of the upper limbs. The purpose of this study was to evaluate the functional outcomes and complications after surgical management of isolated, closed fractures of the proximal phalanx (PP) of the hand (thumb excluded). Surgical management was indicated in 87 PP fractures. Fractures were reduced and fixed with pins, screws or a plate. Functional outcomes were assessed through the range of motion (ROM) in flexion-extension, hand and finger strength, and the QuickDASH and PRWHE scores...

QUESTIONS/PURPOSES: Adolescent idiopathic scoliosis is a 3D spine deformity that worsens during the whole growth. New methods for spinal growth modulation with flexible spinal implants have been described to avoid progression of the deformity during growth spurt. The main limitations are that no specific ancillaries and devices are available, which makes the surgery technically demanding. METHODS: We have developed a new method of spinal growth tethering using minimal invasive videothoracoscopic approach...

BACKGROUND: Menkes disease (MD) is an X-linked recessive neurodegenerative disorder caused by mutations in ATP7A gene. Depending on the residual ATP7A activity, manifestation may be classical MD, occipital horn syndrome, or distal motor neuropathy. Neurological sparing is expected in female carriers. However, on rare occasions, females may manifest with classical clinical phenotype due to skewed X-chromosome inactivation, X-autosome translocation, and XO genotype. Here, we describe a small series of probands with MD and their response to copper histidine therapy...

INTRODUCTION: Distal radius fractures accounts for around 15% of all fractures diagnosed and treated in the emergency rooms. These fractures usually result secondary to high velocity injury such as a motor vehicle accident or fall on an out stretched hand. In the elderly, it is a common fragility fracture. Volar Locking Compression Plates (LCP) is effective devices for fixation of the distal radius fractures. There is a lacuna with regard to literature on the 2.7 mm volar LCP and the current study retrospectively assesses the postoperative radiological outcomes...

Medulloblastoma is a WHO grade IV neoplasm that is usually restricted to the central nervous system, with metastasis occurring along the neuraxis through the ventricular system and cerebrospinal fluid. Extraneural metastasis is rare, usually occurs in bones/lymph nodes, and carries poor prognosis. We report multimodal imaging in a 14-year-old boy with desmoplastic medulloblastoma having multiple extraneural nodal and skeletal metastases, which was misdiagnosed as lymphoma. This case highlights the importance of understanding tumor biology with active clinical and radiological surveillance that is useful in early detection of extraneural metastasis of this aggressive tumor that helps in advocating appropriate and timely treatment...
