Session 7 clinical conditions Flashcards
What is cervical spondylosis
Chronic degenerative osteoarthritis
affecting intervertebral joints in cervical spine
Primary pathology of cervical spondylosis
Age related disc degeneration, marginal osteophytosis, facet joint osteoarthritis
What is the consequence of resultant narrowing of intervertebral foramina in cervical spondylosis
Puts pressure on spinal nerves leading to radiculopathy (dermatomal sensory symptoms and myotomal motor weakness)
Consequence of narrowing of spinal canal in spondylosis
Myelopathy (pressure on spinal cord)
Less common
Global muscle weakness, gait dysfunction, loss of balance, incontinence
What is Jefferson’s fracture
Fracture of anterior and posterior arches of atlas C1
Axial loading
Typically pain but no neurological signs
Occasional complication of Jeffersons fracture
damage to arteries at base of skull
secondary neurological sequelae (ataxia, stroke, Horner’s syndrome)
What is Hangman’s fracture
Axis C2 is fractured through pars interarticularis (between superior and inferior articular processes)
Forcible hyperextension of neck
Unstable- needs treatment
Cause of fractures of the odontoid process and detection
Flexion or extension
open mouth X ray or CT
What is whiplash
forceful hyperextension/hyperflexion injury of cervical spine
tearing of cervical muscles and ligaments
Consequence of whiplash
secondary oedema
haemorrhage
inflammation
Spasm
Sometimes injury to cervical cord
What is myofascial pain syndrome
secondary issue in response to a disc or facet joint injury
Such as whiplash
Protective mechanism against spinal cord injury in whiplash
vertebral foramen is large relative to diameter of cord in cervical region
How can sequestration be resolved
extruded segment of nucleus pulposus is resorbed in spinal canal
Problem with cervical nerves
little space for exiting nerves
Symptoms in C5/C6 left prolapse
parenthesia in radial border of left forearm, thumb and index finger on left
Weakness in left elbow flexion, supination and wrist extension
Pain in neck radiating down left arm over biceps and to skin supplied by C6
