Parameters that effect spine biomechanics following cervical disc replacement

Reoperations Following Cervical Disc Replacement

Cervical disc replacement (CDR) has emerged as an alternative surgical option to cervical arthrodesis. With increasing numbers of patients and longer follow-ups, complications related to the device and/or aging spine are growing, leaving us with a new challenge in the management and surgical revision of CDR. The purpose of this study is to review the current literature regarding reoperations fo...

Effect of Artificial Disc Position on Spine Biomechanics in the Cervical Spine: A Finite Element Study

INTRODUCTION Total disc replacement(TDR) has been suggested for surgical method to treat degenerative disc disease of the cervical spine because it decompresses nerves and preserves motion segments. The short-term outcomes of the TDR of cervical spine has been well reported to treat degenerative disc diseases as a motion preservation technique in spite of some clinical controversies such as imp...

Characteristics of cervical sagittal parameters in healthy cervical spine adults and patients with cervical disc degeneration

BACKGROUND The cervical sagittal parameters of the normal population and the impact of disc degeneration on cervical sagittal alignment have not been clearly defined yet. This study is applied to investigate the characteristics and relationships of cervical sagittal parameters in normal adults and patients with cervical disc degeneration. METHODS We reviewed 50 normal control subjects (normal...

Heterotopic Ossification Following Cervical Total Disc Replacement: Iatrogenic or Constitutional?

OBJECTIVE To elucidate etiological factors of heterotopic ossification (HO) by evaluating retrospectively if HO is a unique finding following cervical total disc replacement (CTDR) or a finding observable following an anterior cervical interbody fusion (ACIF). METHODS The authors had selected 87 patients who underwent anterior cervical surgery (TDR or ACIF), and could be followed up more than...
