The degeneration of uncovertebral joints on CT assessment and its association with postoperative heterotopic ossification in one- or two-level artificial cervical arthroplasty
Background Artificial cervical arthroplasty (ACR) preserves segmental mobility and reduces adjacent segment degenerative disease risk, yet postoperative heterotopic ossification (HO) impairs prosthetic function. Preoperative uncovertebral joint degeneration (UJD) is hypothesized to relate to HO. This study evaluated UJ...
