Redefining the acetabular safe zone to help avoid the risk of dislocation after hip replacement surgery

A study using artificial intelligence to analyze radiographs from thousands of patients after hip replacement surgery redefines the acetabular "safe zone" to help avoid the risk of dislocation, reports The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer.

Persistent opioid use among 12% of patients after cardiac implantable electronic device procedures

About 12 percent of patients who receive implantable cardiac devices such as a pacemaker or defibrillator and fill an opioid prescription after surgery will consistently use the pain medication in the months afterward, raising the potential for addiction following these common procedures and identifying another pathway that could contribute to the national opioid crisis, according to a new study by researchers at the Perelman School of Medicine at the University of Pennsylvania.

Inflammatory cytokines may help predict patient outcomes after traumatic injury

Inflammatory cytokines are molecules that are secreted by immune cells to promote inflammation. A study published in the Journal of Orthopaedic Research found that measuring inflammatory cytokines may help predict patient outcomes after traumatic injury, which is the leading cause of mortality in individuals under 50 years of age.

$Custom plates fabricated through computer modeling may help heal collarbone fractures$

Custom plates fabricated through computer modeling may help heal collarbone fractures

Fractures of the clavicle, or collarbone, are common. Unfortunately, current fixation plates that are used to surgically stabilize these fractures are suboptimal, leading to reoperation rates of up to 53%. A new study published in the Journal of Orthopaedic Research indicates that custom plates developed through computer modeling may be a better option.

Study explains how stem cells can help lizards regenerate better tails

Lizards can regrow severed tails, making them the closest relative to humans that can regenerate a lost appendage. But in lieu of the original tail that includes a spinal column and nerves, the replacement structure is an imperfect cartilage tube.
