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 ]
Type IIIAC: two fracture lines are present, one lateral and one medial. Type IIIBC: two fracture lines are present, one central and one medial. Type IV fractures consist of fractures with more than three intra-articular fractures. Extra-articular fractures include all fractures that do not involve the posterior facet of the subtalar joint.
Interactive Forms is a mechanism to add forms to the PDF file format. PDF currently supports two different methods for integrating data and PDF forms. Both formats today coexist in the PDF specification: [37] [52] [53] [54] AcroForms (also known as Acrobat forms), introduced in the PDF 1.2 format specification and included in all later PDF ...
Clay-shoveler's fracture is a stable fracture through the spinous process of a vertebra occurring at any of the lower cervical or upper thoracic vertebrae, classically at C6 or C7. [1] In Australia in the 1930s, men digging deep ditches tossed clay 10 to 15 feet above their heads using long handled shovels. [ 2 ]
The sliding screw plate (dynamic compression screw, dynamic hip screw) may be used to treat intertrochanteric fractures as well as other injuries. This device consists of a lag screw and a side plate with a barrel. The sliding screw telescopes and provides fixation while allowing impaction to occur at the fracture during healing and weight ...
Vertebral fractures in children or elderly individuals can be related to the development or health of their spine. The most common vertebral fracture in children is spondylolysis which can progress to spondylolisthesis. [11] The immature skeleton contains growth plates which have not yet completely ossified into stronger mature bone. [11]
The NBA and commissioner Adam Silver were eager to make changes to the All-Star Game after last year's contest wasn't very competitive and finished with a final score of 211-186.
A Salter–Harris fracture is a fracture that involves the epiphyseal plate (growth plate) of a bone, specifically the zone of provisional calcification. [2] It is thus a form of child bone fracture. It is a common injury found in children, occurring in 15% of childhood long bone fractures. [3]
