Pediatric allogeneic hematopoietic stem cell transplant (AHSCT) recipients with chronic graft-versus-host disease (cGVHD) are at high risk of endocrinopathies, particularly impaired bone mineral density (BMD). However, rates of BMD impairment in pediatric AHSCT recipients with cGVHD have not been well documented. We describe 33 patients with cGVHD that were referred to the NIH for the Natural History of Clinical and Biological Factors Determining Outcomes in Chronic Graft-Versus-Host Disease Study (NCT 0092235) and underwent formal BMD assessments via dual-energy X-ray absorptiometry (DEXA)...

PURPOSE: Hemivertebra of the cervical spine is a rare but complex spinal malformation. To our knowledge, only one publication describes excision of an upper-middle cervical (between C2 and C4) hemivertebra. We present our experience with two cases of C3 hemivertebra resection and torticollis correction via a combined anterior-posterior-anterior surgical approach and short segment fixation. METHODS: Two 12-year-old patients with torticollis due to congenital C3 hemivertebra underwent surgery consisting of combined anterior vertebral body osteotomy, posterior element resection with segment instrumentation and deformity correction, and iliac bone graft reconstruction and fixation via an anterior approach...

BACKGROUND: Iliac crest has long been the gold standard for lumbar fusion, but concerns over donor site morbidity have led to a wide variety of bone graft substitutes. Despite prolific research, a general consensus is yet to be reached on bone graft materials that lead to optimal fusion. PURPOSE: The purpose of this review is to evaluate the current literature for bone graft material options that maximize fusion rate in posterolateral lumbar fusion surgery. DESIGN: Systematic Review...

BACKGROUND: The transoral approach provides the most direct exposure to extradural lesions of the ventral craniovertebral junction. The morbidity and mortality from this approach greatly limits its use because they are still feared and debated. Using univariable and multivariable logistic regression analyses, this study aims to identify the factors associated with short-term complications in patients undergoing the transoral approach. METHODS: A consecutive cohort analysis of prospectively collected data in several neurosurgery spine departments evaluated 143 consecutive patients who had undergone craniovertebral junction transoral approach surgery...

Management of metastatic spinal disease in the upper cervical spine can be particularly challenging. Depending on the level of the lesion and the patient's anatomy, multiple anterior approaches have been described for resection of the cancer, followed by posterior fixation and instrumentation. Although a single-stage posterolateral approach is now well established for thoracic pathology, less is known about the applicability of these principles when applied as an approach to the cervical spine. The authors present here a case using a posterolateral transpedicular approach for corpectomy and graft placement for circumferential reconstruction as a treatment of metastatic disease in the cervical spine to illustrate the feasibility of this technique, especially in the setting where the patient's anatomy or pathology may impede an anterior or combined circumferential approach...

BACKGROUND: Surgical reconstruction of ligaments and tendons is frequently required in clinical practice. The commonly used autografts, allografts, or synthetic transplants present limitations in terms of availability, biocompatibility, cost, and mechanical properties that tissue bioengineering aims to overcome. It classically combines an exogenous extracellular matrix with cells, but this approach remains complex and expensive. Using a rat model, we tested a new bioengineering strategy for the in vivo and de novo generation of autologous grafts without the addition of extracellular matrix or cells, and analyzed their biomechanical and structural properties...
