Abstract

Eleven revision total hip replacements (THR) were performed with the use of transfemoral distally fixing stems. Nine Wagner and two Link cementless stems were used. The mean age of the patients was 62 years (range 44-78) and in mean they had undergone 2.4 previous hip operations. The mean follow-up was 43 months in nine patients and two patients had a new revision during the follow-up. The reasons for these revisions were loosening of stems in association with proximal lysis and periprosthetic fracture in eight cases, proximal femoral resection after infection in one case, loosening and deficient proximal bone in one case and proximal intraoperative fracture in a dysplastic hip after previous intertrochanteric osteotomy in one patient. The subsidence of the stem varied from 0 to 40 mm and two stems were revised during the first year because stability was lost due to subsidence. In those nine cases who were not revised the mean Harris hip score was 74 points. The final results were excellent in two, good in three, fair in two and poor in four cases. Our results suggest that revision total hip arthroplasty in cases where the proximal femur is deficient after lysis, old infection or fracture, using a distal load bearing stem gives...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.
