Summary

This study tests whether a special traction pad placed between the patient and the surgery table can reduce numbness in the groin area after hip arthroscopy. About 120 patients having hip surgery at Northwestern Memorial Hospital will be asked about numbness and difficulty urinating before and after their procedure. The goal is to see if the pad helps prevent a common side effect of the traction used during surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
The Pink Pad Hip Kit (a traction pad placed between the patient and the traction table)
What this could lead to
If it works, this could reduce post-surgery numbness and discomfort for people undergoing hip arthroscopy.
What could go wrong
This is a small, early-stage study with only 120 participants. The pad may not significantly reduce numbness, and results may not apply to all hip surgery patients.
