The aim of this study was to use mechanics to analytically investigate how extreme locking of intramedullary nails affects the overall biomechanics of intramedullary nail systems. (asme.org)
Placing interlocking screws more extremely in intramedullary nails increases the working length of the nail and leads to the use of longer screws, since at the bone extremities, the width of the medullary cavity increases. (asme.org)

Tumors25
Intramedullary spinal cord tumors (IMSCTs), like the one depicted in the image below, refer to a subgroup of intradural spinal tumors that arise from cells within the spinal cord, as opposed to adjacent structures such as the nerve roots or meninges. (medscape.com)
Most intramedullaryspinal cord tumors are considered to be glial in origin because they are histologically and immunohistochemically similar to differentiated non-neuronal cell types, such as ependymal cells and astrocytes, which occur in nonpathological spinal cord tissue. (medscape.com)
The most commonly encountered intramedullary spinal tumors are ependymomas , astrocytomas , and hemangioblastomas . (medscape.com)
Collectively, spinal ependymomas and astrocytomas account for 80-90% of intramedullary spinal tumors, with ependymomas occurring roughly twice as frequently as astrocytomas. (medscape.com)
Also, neurologic deficits resulting from intramedullaryspinal cord tumors are seldom reversible. (medscape.com)
The first-line treatment for intramedullary tumors is open surgical resection. (medscape.com)
Small asymptomatic lesions may be followed clinically and radiographically because the majority of intramedullary tumors are relatively benign and slow growing. (medscape.com)

Fracture3
One potential complication of intramedullary nailing after a fracture is bone malrotation, where the broken bone is fixated out of alignment and heals incorrectly, causing a rotated limb. (wikipedia.org)
The intramedullary nailing system also allows a 5° range of motion, which makes it easier to insert the nail from the top part of the great trochanter in femoral fracture repair surgery. (medicalwecare.com)
The indications for intramedullary nailing of the radius and ulna include segmental fractures, gunshot fractures with severe comminution, refracture of the forearm after plate removal, fracture occurring above or below an existing plate, unstable fractures in children or adolescents, and fractures in athletes who participate in contact sports.
