Ankylosis

This trial compares two types of knee replacement implants in people aged 75 and older: a standard metal-backed component and a cheaper all-polyethylene (plastic) one. The goal is to see if the all-polyethylene implant performs as well in terms of pain relief, movement, and how l…

This study compares two types of spinal fusion cages—porous titanium and titanium-coated PEEK—in 108 adults undergoing lower back surgery. The goal is to see which cage helps bones fuse better and improves pain and quality of life. Participants were randomly assigned to receive o…

This study follows 183 people aged 14 to 58 who had Lapiplasty surgery for bunions. The goal is to see if starting to walk within 3 weeks after surgery is safe and effective. Researchers will check if the bone heals properly and if the bunion comes back over 24 months.

This study follows 148 adults with cervical disc disease who received the Hexanium ACIF implant, a device placed between vertebrae to restore height and fuse the spine. Researchers will track pain, disability, and any serious side effects for up to 24 months after surgery. The go…

This study tests whether custom-made surgical guides can help surgeons safely and accurately treat children with a stiff or fused jaw joint (TMJ ankylosis). The approach uses a special saw to cut the bone precisely. Eight children under 15 are taking part, and the study checks ho…

This study is tracking 120 people who received a HYPE SCS hip stem during total hip replacement. Researchers will monitor how long the implant lasts, how satisfied patients are, and any complications over 5 years. The goal is to confirm the device is safe and works as intended in…

This study looks at cells from 60 spine surgery patients to find which ones are best at making bone. The goal is to improve healing after spinal fusion and lower the chance of needing another surgery. Researchers will test a small piece of bone graft taken during the operation.
