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] Pars interarticularis marked with red lines. Spondylolysis has a higher occurrence in the following activities: [5] Baseball; Military service; Tennis ...
The pars interarticularis, or pars for short, is the part of a vertebra located between the inferior and superior articular processes of the facet joint. [1] [2] In the transverse plane, it lies between the lamina and pedicle. In other words, in the axial view, it is the bony mass between the facets that is anterior to the lamina and posterior ...
A bone fracture of the shoulder involves a partial or total crack through one of the three bones in the shoulder, the clavicle, the scapula, and the humerus. The break in a bone usually occurs as a result of an impact injury, such as a fall or blow to the shoulder. Fractures usually involve the clavicle or the neck (area below the ball) of the ...
Joint pain is a common symptom we all experience at some point or another. Painful joints can have a significant impact on quality of life and the ability to do daily activities.
People with previous surgical interventions face more chances of articular cartilage damage due to altered mechanics of the joint. Articular cartilage damage may also be found in the shoulder causing pain, discomfort and limited movement. Cartilage structures and functions can be damaged. Such damage can result from a variety of causes, such as ...
The hardening of the shoulder joint capsule is central to the disease process. This is the result of scar tissue around the joint capsule. [14] There also may be a reduction in synovial fluid, which normally helps the shoulder joint, a ball and socket joint, move by lubricating the gap between the humerus and the socket in the shoulder blade.
Motorcycle accidents and sports injuries usually cause this type of injury to brachial plexus. [14] Upward traction also results in the broadening of the scapulo-humoral angle but this time the nerves of T1 and C8 are torn away. Humeral fractures and shoulder dislocations can also cause this type of injury with high energy injuries. [14]
The shoulder joint is a "ball-and-socket" joint. [5] However, the 'socket' (the glenoid fossa of the scapula) is small, covering at most only a third of the 'ball' (the head of the humerus). It is deepened by a circumferential rim of fibrocartilage, the glenoidal labrum. Previously there was debate as to whether the labrum was ...
