Background: Inadequate soft-tissue tension in total hip arthroplasty is regarded as one cause of dislocation or abductor muscle weakness. The purpose of the present study was to assess how the postoperative discrepancy in limb offset (consisting of both femoral offset and acetabular offset) affects...

Over the past year, there have been many changes in hip arthroplasty. Some of the new information further solidifies practices such as the use of tranexamic acid for blood conservation and the detection of infection through alpha defensins, and other studies have enhanced our knowledge of surgical a...

Background: Acupuncture reportedly relieves chronic knee pain and improves physical function in patients diagnosed with osteoarthritis, but the duration of these effects is controversial. The aim of this study was to evaluate the temporal effects of acupuncture on chronic knee pain due to knee oste...

Background: The purpose of this study was to examine (1) timelines for return to sport and work following high tibial osteotomy (HTO), and (2) whether patients return to sport and work at levels similar to preoperative levels.

We present simple techniques for revision shoulder arthroplasty using a telescoping osteotome technique for glenoid removal, an open-book (vertical) osteotomy technique for extraction of the humeral stem and the use of an ultrasonic device and carbide burr for clearing bone and cement mantles.

A surgery for quadriplegics called tendon transfer can significantly improve hand and elbow function, but the procedure is greatly underused, according to an article in the journal Hand Clinics by Loyola Medicine hand surgeon Michael S. Bednar, MD, FAAOS.

A research team has discovered a pair of tissue biomarkers that directly contribute to the harmful joint degeneration associated with spine osteoarthritis.

Researchers at Iowa State University have discovered what could lead to a new treatment for spinal muscular atrophy, a potentially fatal genetic disorder in young children.

Physicians at Rush University Medical Center became the first in Illinois to inject AST-OPC1 (oligodendrocyte progenitor cells), an experimental treatment, into the damaged cervical spine of a recently paralyzed man as part of a multicenter clinical trial.

For the first time, scientists found that in spinal muscular atrophy (SMA), the affected nerve cells that control muscle movement, or motor neurons, have defects in their mitochondria, which generate energy used by the cell. Impaired mitochondrial function and structure in motor neurons were discove...
