SST vocab Flashcards
Arthordesis
The surgical fixation of a joint to promote fusion of the bones
Crankshaft deformity
A potential deformity which occurs when the posterior elements of a skeletally immature patient fuse. the vertebral bodies may continue to grow after posterior fusion resulting in a deformity resembling the crankshaft of an automobile engine
Decompensation
Relative to scoliosis the loss of spinal balance when the thoracic cage is not centered over the pelvis in the coronal plane.
Discectomy
The removal of all or part of the intervertebral disc
Discogram
Radiograph procedure in which contrast material is injected into the intervertebral disc under fluoroscopy, and the patency of the disc is evaluated
Etiology
The cause or origin of the pathology
Hyperkyphosis
A spinal deformity of the sagittal plane and which excessive flexion occurs the deformity may be smooth with the small degree of excesses flexion at multiple levels or angular with acute flexion at one or two segments commonly referred to as humpback or hunchback
Hypokypohsis
Alignment of the sagittal plane in which there is less than the normal amount of flexion but where the sagittal plane continues to have an anterior concaveitu
Ablation
The removal of a body part or destruction of its function
Iatrogenic
The clinical response usually unfavorable to a medical or surgical treatment
Idiopathic
Of unknown cause or etiology
Kyphosis
The posterior curve in the sagittal plane of the spine a normal spine has has a kyphotic curve at the thoracic level of approximately 20° to 40° as well as the sacral kyphosis
Lamella
The layers of collagen and elastin fibers that are arranged concentrically to make up the annualus fibrosis of the intervertebral disc
Laminectomy
Surgical removal of part or all of the posterior vertebral elements to allow space for the neural structures
Laminoplasty
Surgical reconstruction of the posterior vertebral elements to increase space for the neural structures while maintaining the posterior arch
