The ligaments of the sacroiliac joint were investigated, using 7-T MRI and thin slice plastination of 2 pelves as well as frozen sections of 32 specimens. A virtual reconstruction was accomplished and geometric figures have been created for each of the structures. Gender-dependent parameters were obtained for the sacroiliac joint ligaments.

We investigated the reaction of glial cells and endoneurial macrophages in the dorsal root ganglion after application of nucleus pulposus. Activation of dorsal root ganglion glial cells and endoneurial macrophages might play an important role in the pathogenesis of the neuropathic pain state by secreting proinflammatory cytokine and neurotrophin.

This biomechanical study examined 6 human cadaveric spines, and found that crosslinks significantly increase stiffness in axial rotation, but do not achieve intact stability. Improvement in lateral bending was seen, even beyond intact stiffness levels. No improvement with crosslinks was observed to reverse significant instability in flexion.

We investigated the accuracy of clinical handheld goniometer measurements of axial neck rotation compared to measurements using functional CT scans in a sample of patients that had C2 fractures. Results scrutinize goniometer measurements in outcome research of C1–C2 rotation following C2 fracture treatment.

This comparison between the SPORT degenerative spondylolisthesis and spinal stenosis cohorts revealed similar baseline characteristics but better surgical outcomes for the degenerative spondylolisthesis patients. Nonoperative outcomes were similar for the 2 groups. These patient populations have heterogeneous outcomes and should probably not be combined in future studies.

Hybrid constructs using Universal Clamps were compared to those with thoracic hooks in patients treated for adolescent idiopathic scoliosis. The Universal Clamps achieved better thoracic coronal correction, kyphosis, and apical rotation. These differences were stable at last follow-up. Operative time and blood loss were significantly without intraoperative complication.

In 101 females with adolescent idiopathic scoliosis, the Cobb angle explained more variance in Scoliosis Research Society-22 (SRS-22) domains using segmented models with a threshold, but associations were weak. Surface topography was not strongly associated with SRS-22 variables. SRS-22 scores were stable until the curve reached a ≈45° threshold and declined with increasing internal deformity.

Surgical site infections are a cause of postoperative morbidity and mortality. This study explored the hypothesis that perioperative administration of blood products is a risk factor for surgical site infections after spine surgery. Our findings support theories that blood transfusions have modulatory effects on the immune system of the recipients.

We used a combined aspiration technique with a novel cannula design, and employed an existing experimental leakage model to examine the risk of leakage in vertebral body augmentation. It showed that both the quality of cement filling improved significantly and that displaced bone marrow was successfully aspirated, reducing the risk of embolism.
