Object. The authors compared the incidence of radiologically documented changes and symptomatic adjacent-level cervical disc disease after single-level discectomy and subsequent cervical fusion or arthroplasty in two independent prospective clinical studies. Methods. The patients were treated with the Affinity Anterior Cervical Cage System or the Bryan Artificial Cervical Disc. In each study the patients were required to undergo serial cervical radiography preoperatively and 24 months postoperatively, as well as serial clinical evaluations including documentation of adverse events, neurological status, and results of the 36-item Short Form Health Survey. All serial radiographs were reviewed prior to evaluating the clinical symptoms for development of increasing or new adjacent degenerative disc disease (DDD). Subsequently, the clinical data were analyzed. For various reasons of exclusion, the cases analyzed in the Bryan disc—treated cohort consisted of 74 patients and in the Affinity system—treated cohort there were 158 patients. New anterior osteophyte formation or enlargement, increased narrowing of an interspace, new DDD, and calcification of the anterior longitudinal ligament were the radiological findings indicative of adjacent-level disease. Fusion was associated with a significant increase in x-ray film—based changes of adjacent-disc disease (p = 0.009, odds ratio [OR] 2.44). In the cage fusion series, the incidence of symptomatic adjacent-level DDD was statistically greater than that in the group treated with the artificial disc (p = 0.018), and the patients required a statistically greater number of medical treatments related to episodic symptoms of neck, shoulder, and arm pain attributed to new disc disease (p = 0.001, OR 35.8). Conclusions. In comparing these prospective studies the authors demonstrated that maintaining motion rather than fusion will prevent symptomatic adjacent-disc disease and will decrease adjacent-level radiological indicators of disease at a 24-month postoperative interval.

Adjacent Disc Disease

The interest to decrease the complications and morbility in patients, encourage the investigation to search for minor invasvies surgical techniques. The medical responsability for the wellness of the patient adds to the actual advanced technologies that is the origin to propose more efficent interventions. An example is the XLIF (extreme laterla interbody fusion) represents one of the avant-gard techniques of spine surgery. The XLIF represents an excelent option for the treatment of some spine compelx pathologies that needs descompression, balance alignement, arthrodesis and stabilization: degenerative disc disease, spondylolisthesis grade l and ll, deformities like degenerative scoliosis or adjacent disc disease are examples where the benefit of this technicc is evident.

However, this method is contraindicated for L5-S1 (limited by iliac crest) disc disease or spondylolisthesis grade lll for example.

Spine Motion

Intervertebral disc degeneration in the cervical spine is a common condition that often manifests as cervical disc disease, resulting in pain, motor weakness and sensory deficits. The most common surgical treatment strategy involves removal of the diseased disc and fusion of the adjacent vertebrae. Although fusion typically relieves symptoms at the surgical site, evidence of degeneration in the adjacent disc has been reported in 25–92% of patients [1,2]. It has been hypothesized that the progression of adjacent segment degeneration is a result of increased motion at the segments adjacent to the site of fusion [3]. As a response to this proposed mechanism of degeneration, artificial discs were designed with the goals of preserving motion at the operative site and maintaining normal motion in the adjacent segments. However, the extent to which normal adjacent segment motion is maintained in artificial disc patients compared to fusion patients remains unknown. Thus, the objective of this study was to compare the dynamic, three-dimensional (3D) motion of the cervical spine in fusion patients and artificial disc replacement patients.

Abstract Background This study was undertaken to determine the relationship between intervertebral endplate changes and intervertebral disc disease. This study was designed as a cross-sectional, observational study. Two hundred thirteen canine MRI scans performed between 2007 and 2014 were retrieved from a digital image archive. Scans which included any sagittal sections of the vertebral column from C1 to S1 were assessed for morphological changes to the vertebral endplate. Results There was found to be a significant association between vertebral endplate changes and intervertebral disc disease of the adjacent disc (P = 0.021). There was not found to be any significant association between dogs having vertebral endplate changes and having intervertebral disc disease (P = 0.38). There was found to be a highly significant association between discs with vertebral endplate changes on both associated vertebrae (bilateral) and having intervertebral disc disease (P = < 0.0001). Conclusions The presence of endplate changes should alert the observer to closely examine the disc, as intervertebral disc disease is mildly more likely to occur adjacent to these changes.

Abstract The incidence of cervical and lumbar fusion surgery has increased in the past twenty years, and during follow-up some of these patients develop changes at the adjacent segment. Recognizing that adjacent segment degeneration and disease may occur in the future does not alter the rating for a cervical or lumbar fusion at the time the patient's condition is determined to be at maximum medical improvement (MMI). The term adjacent segment degeneration refers to the presence of radiographic findings of degenerative disc disease, including disc space narrowing, instability, and so on at the motion segment above or below a cervical or lumbar fusion. Adjacent segment disease refers to the development of new clinical symptoms that correspond to these changes on imaging. The biomechanics of adjacent segment degeneration have been studied, and, although the exact mechanism is uncertain, genetics may play a role. Findings associated with adjacent segment degeneration include degeneration of the facet joints with hypertrophy and thickening of the ligamentum flavum, disc space collapse, and translation—but the clinical significance of these radiographic degenerative changes remains unclear, particularly in light of the known presence of abnormal findings in asymptomatic patients. Evaluators should not rate an individual in anticipation of the development of changes at the level above a fusion, although such a development is a recognized possibility.

Penelitian ini bertujuan mengetahui hubungan serum lipid darah dengan degenerative disc disease berdasarkan klasifikasi pfirrmann menggunakan magnetic resonance imaging lumbosacral pada pasien nyeri punggung bawah. Penelitian ini dilaksanakan di Departemen Radiologi RS. Dr. Wahidin Sudirohusodo Makassar mulai bulan Oktober 2018 sampai Januari 2019. Subjek sebanyak 52 orang dengan rentang usia 30 - 60 tahun. Metode yang digunakan adalah uji Spearman. Hasil penelitian menunjukkan terdapat korelasi antara kadar low-density lipoprotein (LDL) dan trigliserida serum dengan degenerative disc disease dengan nilai p=0.02 (p0.05). Semakin tinggi kadar LDL dan trigliserida maka derajat degerative disc disease cendereng semakin berat. Tidak terdapat korelasi antara HDL dengan degenerative disc disease. Secara statistik tidak terdapat korelasi antara kolesterol total dengan degenerative disc disease. Namun, didapatkan pada grafik nilai kolesterol total pada setiap derajat degenerative disc disease meningkat.
