“…Subsidence rates with filled PEEK cages were reported to be 0% at six months by Cho et al [14] and at 12 months by Niu et al [13], and Liao et al [16]. In recent case series by Godlweski et al [17] on 100 patients following ACDF with PEEK cages filled with phosphocalcic hydroxyapatite, the subsidence rate was found to be 10.23% at 12 months follow-up.…”

“…The subsidence rate was evaluated vaguely by radiographs in three studies [14,16,23]. Three studies defined subsidence as the radiographic change of at least 3 mm in the interbody space [13,17,24,25], whereas another two studies considered subsidence as a change of at least 2 mm in the interbody distance [21,22]. Kim et al [20] defined subsidence as a decrease of interbody height by more than 2.5 mm on lateral radiographs.…”

“…Ofluoglu et al[30] reported a 6.4 mean change in VAS for neck pain and 6.6 mean change in VAS for arm pain at 13 months following ACDF with ß-TCP filled PEEK cages. Godlewski et al[17] found an improvement in the mean VAS by 2.84 at 12 months of follow-up with phosphocalcic hydroxyapatite filled PEEK cages.…”

The procedure of anterior cervical discectomy and fusion is considered as the treatment of choice in degenerative disc disease, which material provides the best clinical and radiological fusion and other outcomes remains heavily debated. Materials that augment the process of fusion consist of bone grafting, titanium, polyetheretherketone (PEEK), or carbon cages. The application of PEEK cages has been recommended as it is radiolucent, and it has a modulus of elasticity that is similar to cortical bone. PEEK cages can be either filled with various materials or unfilled cages. Filled PEEK cages can include bone autografts, bone allografts, demineralized bone matrix, and other materials that facilitate fusion. This narrative review highlights that standalone filled PEEK cages were likely to have better radiological outcomes and satisfactory clinical outcomes for myelopathy when compared with standalone unfilled PEEK cages.

“…Interbody fusion is preferably performed with various types of cages, mostly made of titanium or polyetheretherketone (PEEK). PEEK cages have a modulus of elasticity closely resembling that of cortical bone, which might lead to advantages in load sharing and stress distribution (1).…”

Effect of Social Factors on Surgical Outcomes in Cervical Disc Disease

BackgroundDaily clinical practice shows us how diametrically different surgical outcomes can occur in particular groups of patients sharing the same diagnosis and being subjected to the same treatment. Patient-reported outcomes appear to be significantly influenced by social factors and patients’ emotional status. Data on such variables were collated and analyzed statistically with the aim of confirming our clinical observations.MethodsWe analyzed a group of 100 patients following cervical disc surgery. The clinical evaluation was based on a visual analog scale (VAS) for pain and the neck disability index (NDI). Non-clinical data comprised education status, employment status, body mass index (BMI), and history of depressive episodes in the period immediately preceding the surgery, which was investigated using the Beck Depression Inventory (BDI).ResultsPatients who had completed university or secondary school education had a significantly lower BMI and lower BDI scores and they reported less pain at 12 months postoperatively than patients with vocational or elementary school education only. Patients who were employed at the time of the study or were retired demonstrated significantly lower NDI scores both before the surgery and at 12 months postoperatively, as well as lower BDI scores compared to those who were unemployed or drew disability pensions. Factors such as age or BMI score did not exert a direct effect on treatment outcomes assessed as changes in the VAS and NDI scores.ConclusionsSurgical treatment for the cervical disc disease decreases pain and improves patients’ quality of life. Treatment outcomes are also influenced by social factors and patients’ emotional status.

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. The degree of mobility of segments directly above and below the implant insertion site was calculated. Measurements were performed the day before the surgery and 12 months post-surgery. Functional (flexion and extension) radiographs of the cervical spine and CT scans obtained 12 months post-surgery were used to evaluate the fusion status. The results were subjected to statistical analysis. Results Statistically significant increase in mobility was recorded for the segments situated immediately below the operative site, with a mean change in mobility of 1.7 mm. Complete fusion was demonstrated in 101 cases (71.1%), and partial fusion in 43 cases (29.9%). In the complete fusion subgroup, the ranges of both flexion and extension in the segments directly below the operative site were significantly greater than those in the partial fusion (pseudoarthrosis) subgroup. Conclusion The mobility of the adjacent segment below the implant insertion site was significantly increased at 12 months post-ACDF surgery. The range of this compensatory hypermobility was significantly greater in patients with complete fusion at the ACDF site than in cases of pseudoarthrosis. Implant subsidence was not associated with mobility changes in the segments directly above or directly below the site of ACDF surgery.
