Bilateral Pedicle and Crossed Translaminar Screws in C2
Multiple techniques exist for the fixation of C2, including axial pedicle screws and bilateral translaminar screws. We describe a novel method of incorporating both the translaminar and pedicle screws within C2 to improve fixation to the subaxial spine in patients requiring posterior cervical instrumentation for deformity correction or instability. We report three cases of patients with cervica...
متن کاملSimultaneous Use of Both Bilateral Intralaminar and Pedicle Screws for C2 Stabilization
Four patients underwent stabilization surgery using both bilateral C2 pedicle screw (PS) and intralaminar screw (LS). Neural and vascular injury resulting from incorrect screw placement was assessed using computed tomography (CT). The evaluation of bone union was assessed by lateral flexion-extension X-ray films and CT. The symptoms were improved in all patients. There were no intraoperative co...
متن کاملBiomechanical Comparison of Unilateral and Bilateral Pedicle Screws
1 Objective. Little is known about the biomechanical effectiveness of transforaminal lumbar 2 interbody fusion (TLIF) cages in different positioning and various posterior implants used 3 after decompressive surgery. The use of the various implants will induce the stability change 4 in stresses and range of motion (ROM) at the surgical and adjacent segments. Unilateral 5 pedicle screw with or wi...
متن کاملC2 Pars/Pedicle Screws in Management of Craniocervical and Upper Cervical Instability
STUDY DESIGN A retrospective study. PURPOSE To evaluate the efficacy and the safety of craniocervical and upper cervical stabilization by using C2 pars/pedicle screw fixations. OVERVIEW OF LITERATURE The management of craniocervical and upper cervical instability has progressed over the past two decades due to good achievements in the instrumentation and the increased awareness on spinal an...
متن کاملComparison between Bilateral C2 Pedicle Screwing and Unilateral C2 Pedicle Screwing, Combined with Contralateral C2 Laminar Screwing, for Atlantoaxial Posterior Fixation
STUDY DESIGN A retrospective study. PURPOSE To compare clinical and radiological outcomes between bilateral C2 pedicle screwing (C2PS) and unilateral C2PS, combined with contralateral C2 laminar screwing (LS), for posterior atlantoaxial fixation. OVERVIEW OF LITERATURE Posterior fixation with C1 lateral mass screwing (C1LMS) and C2PS (C1LMS-C2PS method) is an accepted procedure for rigid at...
