Spinal cord compression - degenration, tumour Flashcards
Three most common causes of neoplastic spinal cord compression original site cancers
Breast
Lung
PROSTATE
Primary spinal tumours -. compression
Myeloma - plasma cells - weakensbone
Lymphoma
Features of spinal cord compression
Back pain - earliest and most common - worse on lying down and coughing
Lower limb weakness
Sensory changes - loss and numbness
Neurological signs - depends on level of lesion
Neuro signs depedning on level of spinal cord compression
Above L1 - UMN signs in legs and perianal numbness
Below L1 -> LMN lesions
Tendon reflexes increased bleow and absent at level of lesion
Investigations for spinal cord compression
Whole MRI spine within 24 hours
CT myelography
Blood tests in spinal cord compression
FBC
Renal function
LFTs
Bone profile - elevated calcium
Clotting studies
Further investigations in cancer sus spinal cord compression
Full history and examination.
Ask about constitutional symptoms.
Examination should include checking for lymphadenopathy, breast examination and digital rectal examination.
Further investigation will be guided by the results of the history and examination but often include
Tumour markers e.g. PSA in men, CA125 in women, LDH
Myeloma screen
Chest x-ray
CT of the chest, abdomen and pelvis.
Causes of spinal cord compression
Prolapsed IV disc
Osteoporotic vertebral fracture
Epidural/subrudal haematoma
Epidural/subdrual abscess, vertberal osteomyelitis+discitis (staph aureus)
Trauma
Vertebral subluxation
Management of spinal cord compression - general
Mobilisation
Corticosteroids - dexamethasone
Analgesia
Sphincter function incontinence assessment VTE prophylaxis
Management of spinal cord compression - definitive treatment
Surgical management
Tokuhashi scoring system
Radiotherapy
what offer is patient has a severe neurological impairment (i.e. paraplegia or tetraplegia) for greater than 24 hours,
spinal stabilisation surgery should only be offered for pain relief.
Physical complications
Patients may lose their ability to walk and therefore their care needs will change.
Bladder and bowel incontinence as described above.
Pressure ulcers, infection and DVT risk related to immobility
Related to surgery and radiotherapy treatment.
Surgical complications include wound complications but also any anaesthetic complications such as postoperative atelectasis.
Radiotherapy complications include skin irritation/blistering.
Tokuhashi scoring system
Overall health
The number of non-vertebral bone metastases
The number of vertebral metastases
The number of metastases to other internal organs
Primary cancer
Neurological deficit
Tokuhashi score and preognosis
Fewer than 6 months
6 months to 1 year
Greater than 1 year
