Radial head anterior dislocation and ulna bowing in children: About 3 cases and review of the literature

Abstract

We present three cases of anterior dislocation of the radial head associated with plastic deformation of the ulna in children. It is a Monteggia equivalent lesion type 1 according to the Bado's classification. Radiological diagnosis often goes unnoticed to the untrained eye. The relationship between the radius and the capitulum identifies the dislocated radial head on radiographs AP or lateral. Line Mubarak highlights the bowing of the ulna on radiographs lateral. Evolution is pejorative in the absence of early orthopedic care. Older is the patient and longer is the time between injury and treatment, less good are the clinical and radiological results. The first line treatment is closed reduction of the dislocation of the radial head and the bowing of the ulna. Surgical treatment is indicated in cases of failure of closed reduction. Adequate surgical treatment is that which allows and maintain the reduction. The surgery is the most possible minimally invasive. Open reduction can be associated with various surgical techniques: the annular ligament plasty, the establishment of a transitory pin intra-articular capitulo radiale, the ulna osteotomy, the radial osteotomy. Radial head resection is not indicated in children.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
