Abstract

The purpose of the current prospective study was to determine the midterm results of 68 total ankle replacements with the Scandinavian Total Ankle Replacement (S.T.A.R.) prosthesis. The 65 patients (34 women and 31 men; mean age at surgery, 56.1 years [range, 22-85 years]) were assessed clinically and radiologically after 3.7 years (range, 2.4-6.2 years). Thirty-five patients (54%) were totally pain-free. The overall clinical score was graded as excellent or good in 67 ankles. The American Orthopaedic Foot and Ankle Society hindfoot score improved from 24.7 points (range, 3-44 points) preoperatively to 84.3 points (range, 44-100 points) at followup. Three patients (three ankles, 4.4%) had a ballooning bone lysis on the tibial side. Despite prophylaxis, periarticular hypertrophic bone formation was seen in 43 ankles (63%; 42 patients), associated with a decrease of dorsiflexion and plantar flexion. Nine ankles (13%; nine patients) had revision surgery because of problems with the components and 14 ankles (21%; 14 patients) had secondary or additional operations. All revision or secondary surgeries were successful, and no ankle had to be converted to an ankle arthrodesis. The early experience with the S.T.A.R. ankle implant is en...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.
