BACKGROUND: Ehler-Danlos syndome (EDS) refers to a group of heritable connective tissue disorders; rare manifestations of which are cervical kyphosis and clinical myelopathy. Surgical treatment is described for the deformity in the thoracolumbar spine in adolescents but not for infantile cervical spine. Internal fixation for deformity correction in the infantile cervical spine is challenging due to the diminutive size of the bony anatomy and the lack of spinal instrumentation specifically designed for young children...

A method for x-ray image-guided robotic instrument positioning is reported and evaluated in preclinical studies of spinal pedicle screw placement with the aim of improving delivery of transpedicle K-wires and screws. The known-component (KC) registration algorithm was used to register the three-dimensional patient CT and drill guide surface model to intraoperative two-dimensional radiographs. Resulting transformations, combined with offline hand-eye calibration, drive the robotically held drill guide to target trajectories defined in the preoperative CT...

Background: Craniocervical junction pathology is infrequent in daily neurosurgical practice. In general, most of these lesions are of traumatic or rheumatic origin. Atlantoaxial instability of inflammatory origin (Grisel syndrome) is a rare entity of which only 16 adult cases have been reported in the literature. This pathology is characterized by the development of an osteolytic lesion at the level of the atlantoaxial joint after an infectious event, usually of the upper airways. Case Description: We present the case of a 76-year-old patient who attended our office for clinical symptoms of spinal instability secondary to an osteolytic lesion, with involvement of C1 and C2...

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...

The mechanics of the lumbar spine are heavily dependent on the underlying anatomy. Anatomical measures are used to assess the progression of pathologies related to low back pain and to screen patients for surgical treatment options. To describe anatomical norms and pathological differences for the population, statistical shape modeling, which uses full three-dimensional representations of bone morphology and relative alignment, can capture intersubject variability and enable comparative evaluations of subject to population...

In recent years, ultrasound has been increasingly used to guide needle insertion procedures for spinal anesthesia. The primary anatomical targets are facet joints and epidural spaces. For these procedures, accurate visualization of the spine anatomy is of critical importance. Challenges arising from the interactions between the ultrasound beam and spinal structures including tilt caused by specular reflections, off-axis interference, and reverberations often result in weakened and blurred vertebra surfaces...

Background: C7 has relatively unique anatomy compared to the remainder of the subaxial cervical spine (C3-C6) and upper thoracic spine. The C7 laminar has been previously reported in feasibility and biomechanical studies as an adequate fixation point in contrast to the lateral mass or pedicles, with few reports of its use in clinical practice. The purpose of this study was to review the safety and efficacy of using the C7 laminar as a fixation point in constructs involving the cervical spine and cervicothoracic junction...

OBJECTIVES: Although spinal cord and dorsal root ganglia stimulation may be effective for managing regional pain syndromes, a more targeted approach is perhaps more appealing for discrete anatomical structures. Chronic shoulder pain is a common musculoskeletal problem with significant socioeconomic impact. A peripheral nerve stimulation of the axillary and suprascapular nerves may prove to be effective as a long-term solution for this indication. In anticipation of the future experimental research and clinical utilization, a sound methodology for the lead placement was developed, and its feasibility is tested in a cadaveric study...
