Impact of Implant Size and Position on Subsidence Degree after Anterior Cervical Discectomy and Fusion: Radiological and Clinical Analysis.

Background: Implant subsidence is recognized as a complication of interbody stabilization, although its relevance remains ambiguous, particularly in terms of relating the effect of the position and depth of subsidence on the clinical outcome of the procedure. This study aimed to evaluate how implant positioning and size influence the incidence and degree of subsidence and to examine their implications for clinical outcomes.

Methods: An observational study of 94 patients (157 levels) who underwent ACDF was conducted.

Cervical Sagittal Balance: Impact on Clinical Outcomes and Subsidence in Anterior Cervical Discectomy and Fusion.

Degenerative disease of the cervical spine leads to sagittal imbalance, which may affect treatment results. The purpose of this study was to evaluate changes in selected cervical sagittal balance parameters and their effects on subsidence and clinical outcomes of the procedure. This study encompassed a total of 95 evaluated patients who underwent anterior cervical discectomy and fusion (ACDF).

Irreducible L5/S1 Spondyloptosis in Over 20 Years After Neglected Trauma Treated with Modified Grob's Technique - Case Report.

Introduction: Spondyloptosis, characterized by complete slippage of the upper vertebral body relative to the lower vertebral body, is an exceedingly rare condition. Typically, it occurs as a result of a high-energy injury and is promptly managed. It is uncommon for a patient to present to a spinal surgery unit several decades after the initial incident.

Adjacent segment mobility after ACDF considering fusion status at the implant insertion site.

Purpose: This paper sets out to analyse mobility changes in segments adjacent to the operated segment. Additionally, it investigates the relationship between the degree of fusion in the operated disc space and mobility changes in the adjacent segments.

Methods: In total, 170 disc spaces were operated on in 104 consecutive patients qualified for one- or two-level surgery.

Reliability and Utility of Various Methods for Evaluation of Bone Union after Anterior Cervical Discectomy and Fusion.

Most surgical procedures performed on account of degenerative disease of the cervical spine involve a discectomy and interbody fixation. Bone fusion at the implant placement site is evaluated post-operatively. It is agreed that computed tomography is the best modality for assessing bone union.

Subsidence following cervical discectomy and implant-to-bone ratio.

Background: Implant subsidence is an undesirable effect after anterior cervical discectomy and fusion (ACDF). We investigated the relation between the rate of implant subsidence and the ratio of the implant surface area to the surface area of the adjacent bone.

Methods: We operated 170 disc spaces in a group of 104 patients.

PEEK versus titanium-coated PEEK cervical cages: fusion rate.

Background: Anterior cervical discectomy and fusion (ACDF) is one of the most commonly performed procedures for degenerative cervical disease. The evaluation of fusion status is still not fully standardized, and a variety of measurement methods are used. This study presents our own evaluation of fusion by comparing two types of implants.

Advantages and Disadvantages of the Use of Various Types of Interbody Implants in Cervical Spine Surgery. Critical Review of the Literature.

Background: Most cervical spine procedures in patients with degenerative disc disease involve discectomy and remo-val of osteophytes in posterior vertebral body surfaces followed by interbody stabilisation with an interbody implant. Interbody implants are made of a variety of materials, differing in structural design, shape and surface topography. Considering that fusion between the implant and host bone is crucial for long-term positive outcomes, the choice of an appropriate implant is significantly important clinically and continues to be an important area of study.
