The frequency of re-surgery after lumbar disc Nucleoplasty in a ten-year period

Clinical Neurology and Neurosurgery
Stephan Klessinger

Abstract

Percutaneous disc nucleoplasty (PDN) is a minimally invasive technique. A portion of the nucleus tissue is ablated using the Coblation technique. Re-surgery is an important factor for the clinical outcome. However, the rate of subsequent surgery after PDN is still unknown. The aim of the present study was to investigate the frequency of an additional open surgery after PDN in a retrospective of more than ten years. Retrospective observational study. Consecutive patients who underwent PDN between 2005 and 2006 were included. Patient's satisfaction was evaluated using MacNab's outcome criteria. The patient data (age and gender), the MRI findings (annular fissure or contained herniation) and the follow-up time was evaluated. A distinction was made between patients with only lumbago and patients with radiating pain. The focus of this study was to evaluate the necessity of an additional surgery at the same level. The period of time between the PDN and re-surgery was analyzed. In total, 203 patients were included in this study. All patients were seen one month after PDN. The follow-up time was longer than five years in 41 patients (20.2%), and longer than 10 years in 16 patients (7.9%). The short-term success rate was 63.5%; however,...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.
