Posterior capsulorrhaphy for treatment of recurrent posterior glenohumeral instability

Abstract

The surgical treatment of recurrent posterior shoulder instability via a posterior approach has had a variable degree of success reported in the literature with recurrence rates ranging between 8% and 45%. The purpose of this study was to review the results of posterior capsulorrhaphy in a consecutive series of patients with recurrent posterior instability. Seventeen consecutive patients underwent operative management for posterior glenohumeral instability. The dominant shoulder was involved in ten patients. All patients were male with an average age of 28.1 years (range: 16 to 54 years). Ten patients had sustained a specific injury which precipitated the instability. Six patients reported dislocations requiring formal closed reduction maneuvers; the remainder described episodes of recurrent subluxation with spontaneous reduction. All patients underwent a posterior capsulorrhaphy using an infraspinatus splitting approach. Eight shoulders required repair of a posterior capsulolabral detachment. In addition, one patient required augmentation with a posterior bone block for significant glenoid rim deficiency. Outcome was assessed by personal interview, clinical assessment, and standardized radiographs. At an average follow-up of 3...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.
