This study evaluates the short-term clinical outcome, radiological, histological and device retrieval findings of two patients with second generation lumbar total disc replacement (TDR). ⋯ Although wear was unrelated to the reason for revision, this study demonstrates the presence of UHMWPE particles and inflammatory cells in second generation TDR. Long-term follow-up after TDR is indicated for monitoring wear and implant status.

Comparative Study
Use of a personalized hybrid biomechanical model to assess change in lumbar spine function with a TDR compared to an intact spine.
Total disc replacements (TDRs) have been employed with increasing frequency in recent years with the intention of restoring natural motion to the spine and reducing adjacent level trauma. Previous assessments of the TDRs have subjectively measured patient satisfaction, evaluated sagittal range of motion via static imaging, or examined biomechanical loading in vitro. This study examined the kinematics and biomechanical loading of the lumbar spine with an intact spine compared to a TDR inserted at L5/S1 in the same spine. ⋯ At levels above the TDR insertion, larger ROM was present during the lifting conditions. Sagittal motions were often greater at the higher lumbar levels, but there appeared to be less lateral and twisting motion. Collectively, this analysis indicates that the insertion of a TDR significantly alters the function of the spine.

To report on a female patient diagnosed with Currarino's triad in adulthood. ⋯ In (young) patients with anorectal malformations, although having no other symptoms, further examination might be required to exclude Currarino's triad. Importance of early diagnosis and multidisciplinary assessment is recommended to establish adequate treatment if needed.

To report a case of Veillonella spondylodiscitis in a healthy 76-year-old lady. ⋯ The aim of this report is to bring Veillonella spondylodiscitis to the attention of spinal surgeons and infectious disease specialists and discuss the management options.

Patients requiring anterior-posterior thoracic spine stabilization and suffering from concomitant cardiopulmonary disease are at increased risk to develop procedure-related complications. In order to reduce cardiopulmonary complications, the efficacy of a posterolateral transpedicular approach for 360-degree fusion was investigated. ⋯ The posterolateral transpedicular approach might be a safe, less-invasive and efficient alternative to anterior-posterior fusion. However, biomechanic efficacy and long-term outcome as compared to the transthoracic technique remains to be studied in a larger patient cohort.
