“…The effects of a disc implant at the L5-S1 spine segment were assessed in a finite-element model of the lumbar spine. Depending on the anteroposterior location of the implant, the sum of flexion and extension range of motion can vary from 11.5 • to 15 • , demonstrating that the range of motion depends on where the surgeon places the implant (49). Furthermore, under lateral bending on the ipsilateral side, lumbar facet joint forces as a function of cranial/caudal implant location can range from 70 to 115 N, possibly leading to disruption of articular cartilage homeostasis (49).…”

Another study concluded that, after cervical disc replacement, the range of motion in the associated facet joints increased from 9.6 (50).…”

The zygapophysial joint, a diarthrodial joint commonly referred to as the facet joint, plays a pivotal role in back pain, a condition that has been a leading cause of global disability since 1990. Along with the intervertebral disc, the facet joint supports spinal motion and aids in spinal stability. Highly susceptible to early development of osteoarthritis, the facet is responsible for a significant amount of pain in the low-back, mid-back, and neck regions. Current noninvasive treatments cannot offer long-term pain relief, while invasive treatments can relieve pain but fail to preserve joint functionality. This review presents an overview of the facet in terms of its anatomy, functional properties, problems, and current management strategies. Furthermore, this review introduces the potential for regeneration of the facet and particular engineering strategies that could be employed as a long-term treatment.

“…9 The amount of iatrogenic distraction, the preoperative disc height, and the positioning of the implant have been considered important for surgical success. Thus, Dreischarf et al 4 state that its effect on the postoperative range of motion and on facet load deserve additional discussion. In this sense, the authors developed a study to investigate the biomechanics of the L5-S1 motion segment following TDR.…”

“…3 In this sense, total disc replacement (TDR) has emerged as an alternative to overcome the negative effects of spinal fusion. 4 TDR has been receiving more attention in recent years. This procedure is designed to maintain the movement of the operated level and prevent degeneration of the adjacent segment.…”

With the increase in the elderly population worldwide, the prevalence of degenerative diseases tends to grow, especially degenerative disc disease (DDD) in the lumbar spine. It is important to seek excellence treatments to ensure a better quality of life for patients. In this sense, the total disc replacement and the use of prostheses in the lumbar spine have been pointed out as alternative and promising treatments when compared to the standard treatment. The aim of this study is to show the results of total replacement of the intervertebral disc, through a review of the literature. The electronic search was performed in the PubMed databases, with the keywords “Total Disk Replacement”, “Low Back Pain”, and “Arthroplasty” in articles published as of 2012. We selected 16 articles. Level of Evidence: II. Type of study: Systematic reviewb of Level II studies or Level I studies with inconsistent results.

“…Many of the cited complications such as implant extrusion and vascular injury can be linked to inadequate training, improper sizing and lack of confirmation of satisfactory placement on imaging [107] with implant impingement linked to the aforementioned factors [108]. Design variables relating to constraint and core mobility have also been shown to alter wear and force transmission in in vitro studies [109,110].…”

Operative Management of Lumbar Degenerative Disc Disease

Lumbar degenerative disc disease is extremely common. Current evidence supports surgery in carefully selected patients who have failed non-operative treatment and do not exhibit any substantial psychosocial overlay. Fusion surgery employing the correct grafting and stabilization techniques has long-term results demonstrating successful clinical outcomes. However, the best approach for fusion remains debatable. There is some evidence supporting the more complex, technically demanding and higher risk interbody fusion techniques for the younger, active patients or patients with a higher risk of non-union. Lumbar disc arthroplasty and hybrid techniques are still relatively novel procedures despite promising short-term and mid-term outcomes. Long-term studies demonstrating superiority over fusion are required before these techniques may be recommended to replace fusion as the gold standard. Novel stem cell approaches combined with tissue engineering therapies continue to be developed in expectation of improving clinical outcomes. Results with appropriate follow-up are not yet available to indicate if such techniques are safe, cost-effective and reliable in the long-term.
