Rotational Vertebral Artery Dissection Secondary to Anomalous Entrance into Transverse Foramen.

Background: Rotational vertebral artery occlusion is a rare syndrome characterized by vertebrobasilar insufficiency secondary to position-dependent occlusion of the vertebral artery. Most cases reported in the literature have been attributed to osteophytic compression, either from the occipital condyle or within the transverse foramen. However, vertebral artery dissection secondary to motion in the setting of anomalous anatomy has not been reported.

Biomechanics of Posterior Dynamic Fusion Systems in the Lumbar Spine: Implications for Stabilization With Improved Arthrodesis.

Study Design: A comparative biomechanical human cadaveric spine study of a dynamic fusion rod and a traditional titanium rod.

Objective: The purpose of this study was to measure and compare the biomechanical metrics associated with a dynamic fusion device, Isobar TTL Evolution, and a rigid rod.

Summary Of Background Data: Dynamic fusion rods may enhance arthrodesis compared with a rigid rod.

Peripheral nerve stimulation for the treatment of occipital neuralgia and transformed migraine using a c1-2-3 subcutaneous paddle style electrode: a technical report.

In this article we will discuss the treatment of Occipital Neuralgia (ON) and Transformed Migraine (TM) using a paddle style surgical stimulator lead. A paddle style electrode may have advantages to the cylindrical style in reducing migrations from cervical tension or anchor dislodgement. It should be considered in refractory "neuropathic" cervicocranial syndromes such as ON and TM before moving on to more aggressive surgical interventions.

Brachial plexopathy due to chondrolipoangioma. Case report and review of the literature.

Chondrolipoangioma is a mesenchymoma primarily composed of cartilage, with adipose tissue and vascular elements present in lesser proportions. Chondrolipoangiomas have been reported to occur in the extremities, chest wall, oral soft tissues, mediastinum, uterus and its round ligament, seminal vesicles, and heart. In this report, the authors present an unusual case in which a chondrolipoangioma caused a brachial plexopathy.

Dural repair using acellular human dermis: experience with 200 cases: technique assessment.

Objective: Many craniotomies require a watertight dural closure. When primary dural repair is not possible, a graft is necessary. Autograft material is not always easily accessible or available, necessitating the use of other material.
