“…Similarly, researchers found that lateral dislocation of the prosthetic led to severe acute pain and required revisions and fusions. However, there were no noted long-term complications of these dislocations [28,30]. The underlying issue is commonly attributed to prosthesis under-sizing, and no standardized way of measuring and fi tting disc prosthetics has been described.…”

“…The underlying issue is commonly attributed to prosthesis under-sizing, and no standardized way of measuring and fi tting disc prosthetics has been described. Furthermore, gaps exist on how heterotopic ossifi cation (HO) can be minimized to prevent long term calcifi cation, however Pokorny, et al [28] showed little correlation between extent of HO and worsened outcomes.…”

Lumbar disc replacement has become an area of interest for many practicing spine surgeons. As newer technology emerges focusing on motion sparing devices, novel techniques are being employed to better serve patients and increase post-operative outcomes. Traditionally, the anterior approach is utilized in total disc arthroplasty of the lumbar spine, although many are beginning to favor the use of a lateral approach. The lateral approach not only allows for the maintenance of the Anterior Longitudinal Ligament (ALL), but also avoids the great vessels during surgery which are encountered in the traditional anterior approach. Research has shown the lateral approach in total disc replacements (TDR) of the lumbar spine to be a not inferior alternative to the anterior approach, with long-term pain relief and a low complication rate.

“…The NSQIP dataset cannot distinguish between different surgical approaches, which have different complication profiles. 13 , 38 , 39 Furthermore, the NSQIP dataset uses hospital billing data to capture inpatient and outpatient status, which may not accurately reflect length of stay. 26 , 40 Consequently, some researchers have treated only patients with a length of stay as zero days as outpatient, and greater than zero as inpatient.…”

Study Design: Retrospective cohort study. Objective: Spine surgery has been increasingly performed in the outpatient setting, providing greater control over cost, efficiency, and resource utilization. However, research evaluating the safety of this trend is limited. The objective of this study is to compare 30-day readmission, reoperation, and morbidity for patients undergoing lumbar disc arthroplasty (LDA) in the inpatient versus outpatient settings. Methods: Patients who underwent LDA from 2005 to 2018 were identified using the ACS-NSQIP (American College of Surgeons National Surgical Quality Improvement Program) database. Regression was utilized to compare readmission, reoperation, and morbidity between surgical settings, and to evaluate for predictors thereof. Results: We identified 751 patients. There were no significant differences between inpatient and outpatient LDA in rates of readmission, reoperation, or morbidity on univariate or multivariate analyses. There were also no significant differences in rates of specific complications. Inpatient operative time (138 ± 75 minutes) was significantly ( P < .001) longer than outpatient operative time (106 ± 43 minutes). In multivariate analysis, diabetes ( P < .001, OR = 7.365), baseline dyspnea ( P = .039, OR = 6.447), and increased platelet count ( P = .048, OR = 1.007) predicted readmission. Diabetes ( P = .016, OR = 6.533) and baseline dyspnea ( P = .046, OR = 13.814) predicted reoperation. Baseline dyspnea ( P = .021, OR = 8.188) and ASA (American Society of Anesthesiologists) class ≥3 ( P = .014, OR = 3.515) predicted morbidity. Decreased hematocrit ( P = .008) and increased operative time ( P = .003) were associated with morbidity in univariate analysis, but not in multivariate analysis. Conclusions: Readmission, reoperation, and morbidity were statistically similar between surgical setting, indicating that LDA can be safely performed in the outpatient setting. Higher ASA class and specific comorbidities predicted poorer 30-day outcomes. These findings can guide choice of surgical setting given specific patient factors.

Degenerative disc disease (DDD) has become a significant public health issue worldwide. This can result in loss of spinal function affecting patient health and quality of life. Artificial total disc replacement (A‐TDR) is an effective approach for treating symptomatic DDD that compensates for lost functionality and helps patients perform daily activities. However, because current A‐TDR devices lack the unique structure and material characteristics of natural intervertebral discs (IVDs), they fail to replicate the multidirectional stiffness needed to match physiological motions and characterize anisotropic behavior. It is still unclear how the multidirectional stiffness of the disc is affected by structural parameters and material characteristics. Herein, a bioinspired intervertebral disc (BIVD‐L) based on a representative human lumbar segment is developed. The proposed BIVD‐L reproduces the multidirectional stiffness needed for the most common physiological kinematic behaviors. The results demonstrate that the multidirectional stiffness of the BIVD‐L can be regulated by structural and material parameters. The results of this research deepen knowledge of the biomechanical behavior of the human lumbar disc and may provide new inspirations for the design and fabrication of A‐TDR devices for both engineering and functional applications.
