Safety Issues and Neurological Improvement following C1- C2 Fusion using C1 Lateral Mass and C2 Pedicle Screw in Atlantoaxial Instability [PDF]

Malaysian Orthopaedic Journal, 2010
The evolution of instrumentation methods for C1-C2 fusion from the use of posterior wiring methods to transarticular screws and C1 lateral mass with C2 pedicle screw construct have improved fusion rates to almost 100%. However, the C1 lateral mass and C2

Odontoid screw fixation of a type II odontoid fracture in a patient with autofused C2–C3 vertebral bodies

Interdisciplinary Neurosurgery, 2018
Background: Anterior odontoid screw fixation for the treatment of type II odontoid fractures, in contrast to posterior C1–2 fusion, allows for maintenance of cervical rotatory motion at C1–2. The approach requires an accessible C2–3 disc space from which

Effects of weak anchoring on C1 and C2 chevron structures [PDF]

, 2005
We present a theoretical study of the effect of weak anchoring on the transition between C1 and C2 chevron structures in smectic C liquid crystals. We employ a continuum theory which allows for variable cone, azimuthal and layer tilt angles.

Risk Factors of Nonfusion after Anterior Cervical Decompression and Fusion in the Early Postoperative Period: A Retrospective Study

Orthopaedic Surgery, 2023
Objective Although high fusion rates have been reported for anterior cervical decompression and fusion (ACDF) in the medium and long term, the risk of nonfusion in the early period after ACDF remains substantial.

Clinical and radiological outcomes of patients on whom posterior C1-C2 stabilization is applied in C2 odontoid fractures

Medicine Science, 2021
C2 odontoid fractures constituting 18% of total cervical fractures have a high mortality rate. These fractures may be treated with surgical methods such as external immobilization and odontoid screwing, and anterior or posterior transarticular screwing ...

Biomechanical effects of hybrid constructions in the treatment of noncontinuous cervical spondylopathy: a finite element analysis

Journal of Orthopaedic Surgery and Research, 2023
Background Hybrid construction (HC) may be an ideal surgical strategy than noncontinuous total disc replacement (TDR) and noncontinuous anterior cervical discectomy and fusion (ACDF) in the treatment of noncontinuous cervical spondylopathy.
