A compression fracture is a collapse of a vertebra. It may be due to trauma or due to a weakening of the vertebra (compare with burst fracture ). This weakening is seen in patients with osteoporosis or osteogenesis imperfecta , lytic lesions from metastatic or primary tumors , [ 1 ] or infection. [ 2 ]
Fragility fracture is a type of pathologic fracture that occurs as a result of an injury that would be insufficient to cause fracture in a normal bone. [2] There are three fracture sites said to be typical of fragility fractures: vertebral fractures, fractures of the neck of the femur, and Colles fracture of the wrist.
Sports involving repetitive or forceful hyperextension of the spine, especially when combined with rotation are the main mechanism of injury for spondylolysis. The stress fracture of the pars interarticularis occurs on the side opposite to activity. For instance, for a right-handed player, the fracture occurs on the left side of the vertebrae. [5]
This is a shortened version of the thirteenth chapter of the ICD-9: Diseases of the Musculoskeletal System and Connective Tissue. It covers ICD codes 710 to 739. The full chapter can be found on pages 395 to 415 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
The fracture is often unstable. [1] Treatment may be conservative with the use of a brace or via surgery. [1] The fracture is currently rare. [7] It was first described by G. Q. Chance, a radiologist from Manchester, UK, in 1948. [3] [13] The fracture was more common in the 1950s and 1960s before shoulder harnesses became common. [3] [5]
Bertolotti's syndrome is characterized by sacralization of the lowest lumbar vertebral body and lumbarization of the uppermost sacral segment. It involves a total or partial unilateral or bilateral fusion of the transverse process of the lowest lumbar vertebra to the sacrum, leading to the formation of a transitional 5th lumbar vertebra.
Degenerative disc disease; Other names: Degenerative disc disorder, intervertebral disc degeneration: Degenerated disc between C5 and C6 (vertebra at the top of the picture is C2), with osteophytes anteriorly (to the left) on the lower portion of the C5 and upper portion of the C6 vertebral body.
A flexion teardrop fracture is a fracture of the anteroinferior aspect of a cervical vertebral body due to flexion of the spine along with vertical axial compression. [1] The fracture continues sagittally through the vertebral body, and is associated with deformity of the body and subluxation or dislocation of the facet joints at the injured level. [2]
