The conus medullaris (Latin for "medullary cone") is the tapered, lower end of the spinal cord. It occurs near lumbar vertebral levels 1 (L1) and 2 (L2). The upper end of the conus medullaris is usually not well defined.

After the spinal cord tapers out, the spinal nerves continue to branch out diagonally, forming the cauda equina.

The pia mater that surrounds the spinal cord, however, projects directly downward, forming a slender filament called the filum terminale, which connects the conus medullaris to the back of the coccyx. The tension that the filum terminale provides between the conus medullaris and the coccyx stabilizes the entire spinal cord.^[1]

Blood supply

The blood supply consists of three spinal arterial vessels—the anterior median longitudinal arterial trunk and two posterolateral trunks. Other less prominent sources of blood supply include radicular arterial branches from the aorta, lateral sacral arteries, and the fifth lumbar, iliolumbar, and middle sacral arteries. The latter contribute more to the vascular supply of the cauda equina.

Pathology

Conus medullaris syndrome is a collection of signs and symptoms associated with injury to the conus medullaris.^[2]>

INTRODUCTION: Several treatments are proposed for castration-resistant prostate cancer (CRPC) at the metastatic stage. Monitoring of response using serum prostate-specific antigen (PSA) levels (sPSA) can be insufficient at this stage. Imaging has been proposed, in particular, nuclear medicine functi

Anterior lumbar plate (ALP) systems have been widely used as an effective interbody fusion device for treating spinal cord compression. However, clinical complications, such as implant loosening and breakage, still occur. Past studies have investigated the effects of the screw orientation on the int
