A dislocated shoulder is a common sports injury that can occur with a single swing of the tennis racket or an awkward fall on the field. Though popping the bone back into the socket may seem like a simple solution, the reality is more complex.

The injury can sometimes require an operation, and improper surgical technique and healing can further exacerbate the injury. This puts individuals at increased risk for future dislocation or joint disease later in life.

To tackle this issue, multidisciplinary researchers from the University of Pittsburgh will use an award from the National Institutes of Health to study an individualized approach that may improve surgical outcomes and help athletes avoid lasting repercussions.

Richard Debski, PhD, professor of bioengineering, and Albert Lin, MD, associate professor of orthopaedic surgery, will lead a study to improve injury assessment and repair using quantitative techniques to measure the magnitude and location of injury.

“Repair surgery has up to a 15 percent rate of failure, and these cases lead to instability and additional dislocations which limit the patient’s ability to return to an active life,” said Debski, who runs the Orthopaedic Robotics Laboratory at Pitt’s Swanson School of Engineering.

Our research reveals this injury affects a larger region than previously thought and indicates that the location and magnitude vary from person to personThis suggests that an individualized approach may be more effective in treating dislocation injuries and improving surgical outcomes.”

Dislocation injuries involve a sheet of soft tissue — called a capsule — that surrounds and stabilizes the joint. The high recurrence rate in capsular injuries can enlarge the damaged area, making a successful recovery even more difficult.

“We will use an MRI technique to characterize the injury and compare it to the quantitative patterns from our cadaveric model to see if there is a correlation between the data before and after surgical repair,” said Debski.

The findings of this study could validate the need for an individualized approach to capsular injury repair and potentially lead to a clinical trial.

“With this personalized approach, we hope to reduce the amount of failed capsular surgeries,” Debski said. “In the long run, we also hope to reduce the development of osteoarthritis in young adults, and ultimately, help these athletes make a healthy return to the sport that they love.”
