This study is testing the safety and performance of a spinal implant called the Hexanium TLIF system in adults with degenerative disc disease. The implant is placed during surgery to fuse the spine and restore disc height. Researchers will track pain, disability, and any serious …

This study is testing special screws that dissolve over time, used in foot and ankle surgeries for fractures, realignments, or joint fusions. The screws are meant to hold bones together while they heal, then safely absorb into the body. Researchers will follow 125 adults for 4 ye…

This study compares two types of hip replacement materials in 100 adults aged 18 to 65 who need a total hip replacement. One group gets a ceramic-on-polyethylene implant where the polyethylene is infused with vitamin E to reduce wear. The other group gets a standard ceramic-on-ce…

This trial investigates whether Reiki, a gentle hands-on energy therapy, can help reduce pain and improve recovery in people undergoing lumbar spine surgery. Sixty participants will be randomly assigned to receive either two sessions of real Reiki or a sham (placebo) treatment al…

This study tests whether an ultrasound-guided retrolaminar block (a numbing injection near the spine) can lower the amount of opioids patients need after lumbar spine fusion surgery. Forty-four adults will be randomly assigned to receive either the active block or a sham injectio…
