"effusion"

abnormal accumulation of fluid within a joint cavity, producing swelling and restricting movement

"A large knee effusion was aspirated to relieve pain, and the fluid was sent for culture."

"disc herniation"

protrusion of the nucleus pulposus through the annulus fibrosus of an intervertebral disc, potentially compressing spinal nerves

"The L5–S1 disc herniation caused sciatica radiating to the left foot, prompting surgical referral."

"spinal stenosis"

narrowing of the spinal canal or neural foramina that compresses the spinal cord or nerve roots

"Lumbar spinal stenosis produced neurogenic claudication with walking distances less than fifty metres."

"spondylolisthesis"

forward slippage of one vertebra over the one below, graded I–IV by the percentage of displacement

"A Grade II L4–L5 spondylolisthesis was found incidentally on imaging and monitored conservatively."

"radiculopathy"

pain, numbness, or weakness radiating along the distribution of a spinal nerve root due to compression or irritation

"Cervical radiculopathy at C6 produced paraesthesia in the thumb and index finger."

"myelopathy"

dysfunction of the spinal cord itself, causing upper motor neurone signs such as spasticity and hyperreflexia
