Why is it called clay shoveler's fracture?
Emma Newman It is named for its occurrence in Australian clay miners during the 1930's, who sometimes sustained these fractures when the heavy clay that they tossed over their shoulder was stuck to their long-handled shovel causing a sudden flexion force on the neck and back muscles2.
What is a clay shoveler's fracture?
Clay shoveler's fracture is an avulsion fracture, with avulsion referring to a sudden pulling or tearing away of something. Avulsion fractures typically result from excessive, sudden contracture of muscles that are attached to the spinous processes. (An example of such a muscle is the trapezius.)
What is the name of a fracture to the spinous process called?
Incidents of abrupt torsion in the neck such as whiplash can cause the spinous process to fracture. The fracture called a "clay shoveler's fracture" typically occurs in the upper spine at C6 (cervical 6), C7 (cervical 7) or T1 (thoracic 1).
What is an Odontoid fracture?
Odontoid Fractures are relatively common fractures of the C2 (axis) dens that can be seen in low energy falls in elderly patients and high energy traumatic injuries in younger patients.
What is Jefferson fracture?
A Jefferson fracture is a bone fracture of the vertebra C1. The vertebra C1 is a bony ring, with two wedge-shaped lateral masses, connected by relatively thin anterior and posterior arches and a transverse ligament. The lateral mass on vertebra C1, who is taller, is directed laterally.

21 related questions foundWhat is name of C1 fracture?
A Jefferson fracture is another name for a bone fracture of the front and back arches of the C1 vertebra. The C1 vertebra is the top one, closest to your skull.
What is a Rolando's fracture?
Rolando fractures are intra-articular fractures of the base of the first metacarpal with the detachment of several fragments - typically three. • Rolando fractures account for 21% of fractures of the base of the first metacarpal.
What does the term Odontoid mean?
: a toothlike process projecting from the anterior end of the centrum of the axis vertebra on which the atlas vertebra rotates.
What is the purpose of the odontoid process?
The odontoid process lies anterior to the spinal cord and is used as the pivot for the rotation of the head. The C1 vertebra, carrying the cranium, rotates on this. The craniovertebral joint between the atlas and the axis is called, the atlanto-axial joint.
How does Odontoid fracture happen?
Odontoid fractures occur as a result of trauma to the cervical spine. In younger patients, they are typically the result of high-energy trauma, which occurs as a result of motor vehicle or diving accidents.
What is Flavum?
The ligamenta flavum is a short but thick ligament that connects the laminae of adjacent vertebrae from C2 to S1 and is considered a medial ward continuation of the fact joint . It consists of 80% elastin fibers and 20% collagen fibers.
How serious is spinous process fracture?
A spinous process fracture is a break or crack in the back part of a vertebra. Muscles and ligaments in your back are attached to this part of the vertebra. When a vertebra is damaged, the spinal cord may also be damaged. Most spinous process fractures do not cause spinal cord damage.
What causes a spinous process fracture?
These fractures are caused by trauma from: Falls. Car, motorcycle, or pedestrian accidents. Severe and sudden twisting or bending.
What is spondylolysis?
Spondylolysis is a stress fracture through the pars interarticularis of the lumbar vertebrae. The pars interarticularis is a thin bone segment joining two vertebrae. It is the most likely area to be affected by repetitive stress.
Why is it called a Chance fracture?
A Chance fracture results from a flexion-distraction injury of the spine. Manchester, UK radiologist G.Q. Chance first described this fracture in 1948 as a “horizontal splitting fracture of the spine."[2] The association between the use of lap seat belts and the Chance fracture was not recognized until the 1960s.
Is lumbar spondylosis arthritis?
Technically, spondylosis is a form of arthritis—spinal osteoarthritis (osteoarthritis is the most common type of arthritis) to be exact. We tend to think of arthritis as something you get in your hands and knees, but the spine, and all of its bones and joints, can fall victim to its grip as well.
What is the odontoid process called?
Dens. The dens, also called the odontoid process or the peg, is the most pronounced projecting feature of the axis. The dens exhibits a slight constriction where it joins the main body of the vertebra.
Where do dens articulate?
One of the most prominent features of the axis bone is a superior, tooth-like projection called the odontoid process (or dens). articulates with the anterior arch of the atlas bone, where they form a pivot joint.
What is the structural and clinical significance of the odontoid process on the C2?
The odontoid process, in position between the anterior ring of the atlas ventrally and the transverse ligament dorsally, is the main structure preventing dislocation of C1 on C2. Maldevelopment of the odontoid process or the transverse ligament results in congenital atlantoaxial dislocation and cervical myelopathy.
Which vertebrae has Odontoid process?
The Odontoid process is a projection of the axis, a second cervical vertebra, and joins the main body of the vertebra. So, the correct answer is, ”Second cervical vertebra of mammal”.
What is sacral in medical terms?
Medical Definition of sacral
(Entry 1 of 2) : of, relating to, or lying near the sacrum the sacral region of the spinal cord. sacral.
What is the axis vertebra?
Introduction. The Axis (C2 vertebra) also known as epistropheus forms the pivot upon which the first cervical vertebra (the Atlas), which carries the head, rotates. The axis is composed of a vertebral body, heavy pedicles, laminae, and transverse processes, which serve as attachment points for muscles.
What is a volar Barton fracture?
A palmar Barton's fracture of the right wrist, as shown on a 3D-rendered CT scan. Specialty. Orthopedic. A Barton's fracture is an intra-articular fracture of the distal radius with dislocation of the radiocarpal joint. There exist two types of Barton's fracture – dorsal and palmar, the latter being more common.
What is Galeazzi fracture?
A Galeazzi fracture is a fracture of the middle to distal third of the radius associated with dislocation or subluxation of the distal radioulnar joint (DRUJ).
What is a C1 and C2 fracture?
Fractures of the C1 and C2 vertebrae usually occur together. Fractures may result from diving in shallow water, falling, motor vehicle accidents,1 and/or hitting an obstacle with the forehead or chin. 2. Trauma to C1-C2 may also cause whiplash injury, spondylolisthesis, nerve injury, and/or spinal cord injury.
