Revision for humeral stem loosening: a systematic review.

Introduction: Humeral loosening (HL) is an uncommon indication for revision shoulder arthroplasty. This systematic review describes patient characteristics (prosthetic type removed, reimplanted, and septic vs. aseptic loosening status), re-revision rate, and outcomes following revision surgery for a loose humeral stem.

Common Factors in Shoulder and Hip Arthroplasty Implant Failures: A Historical Review.

In this era of subspecialty care in orthopedics, iterations of implant design can occur in a silo which then precludes gaining knowledge from failures of implant design that may have occurred in different subspecialties. This literature review describes the history of failures in hip and shoulder arthroplasties with the purpose of identifying similar factors that led to previous implant failures. A review of the literature was performed by two reviewers assessing articles that described failed hip and shoulder arthroplasty systems over time.

Thoracic spinal arachnoid web and syringomyelia with rostral expansion to the first cervical spinal cord level: Case report.

Introduction And Importance: A spinal arachnoid web is a rare pathology that has been associated with the development of syringomyelia. Syrinx expansion can occur, which can result in the development of new symptoms. In the current literature, the farthest rostral expansion of the associated syrinx has been to the C3 spinal level.
