Anatomic study of the flexor carpi ulnaris muscle and its application to soft tissue coverage of the elbow with clinical correlation

Abstract

The posterior elbow is prone to soft tissue loss that may require reconstructive methods for wound healing to be achieved. The flexor carpi ulnaris (FCU) muscle has been described for coverage in case reports and small series. Previous studies give conflicting anatomic findings about the dominant vascular pedicle for the FCU. Twenty-five cadaveric specimens were dissected. Pedicle location, number, and distance from the medial epicondyle were recorded along with the extent of posterior elbow coverage. Chart review was conducted during a 4-year period. Eight patients who underwent FCU rotational flap coverage were identified. Those flaps relied entirely on a single proximal pedicle. The vascular pedicles from the ulnar artery or recurrent ulnar artery were identified in 24 of 25 specimens. The average distance from the tip of the medial epicondyle to the first pedicle was 5.7 cm (range, 3 to 10 cm). The length of muscle coverage proximal to the olecranon tip averaged 9.3 cm. The clinical follow-up of 7 patients requiring FCU rotational flaps for coverage of the posterior elbow showed that all flaps survived and provided adequate coverage for the defect. The FCU rotational pedicle flap provides predictable coverage of small to me...Continue Reading

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.
