Vertebral pillar is form by 33 vertebrae and 24 discs . The 33 vertebrae are diffuse in neck ( 7 vertebrae ) , thorax ( 12 vertebrae ) , lumbar ( 5 vertebrae ) , sacrum ( 5 vertebrae ) and coccygeal segments ( 4 vertebrae ) . Intervertebral discs are absent in five sacral and four coccygeal vertebrae , which are fused . Twenty - four discs lie between vertebra in neck , thorax and lumbar segment . Spinal canal is a cylindric hollow structure surrounded by vertebrae , disc and ligaments . The cylindrical spinal duct is stretched between foot of the skull and sacrum . Vertebral column protect spinal corduroy , which lie within spinal canal . Three elusive hempen membranes known as pia , arachnoid and dura mater fence in spinal corduroy . The spinal corduroy is also surrounded by a fluid or water known as cerebrospinal fluid . Cerebrospinal fluid lies between pia and arachnid mater . Spinal cord is protected from injury by vertebral column , three tough unchewable tissue layer and cerebrospinal fluid .
Spinal extradural infinite lies between the dura mater and bones of vertebral column . Spinal extradural quad is disseminate from neck opening below the skull to sacrum . Epidural abscess is one of the rare drive of back pain in the ass . Epidural abscess is triggered by bacterial infection of epidural gentle tissue paper . Epidural abscess is a purulent secretion , which pass around in to extradural blank . turgid epidural abscess spreads over several segments . Collection of extradural pus when retained in extradural space causes pressure symptoms . press symptoms are render by expansion of abscess in extradural space , which finally causes meek to harsh compressing of spinal cord and spinal nerve . extradural abscess is a rarefied medical status and often leads to hospital admission . The published scientific data suggests number of cases accept in the hospital with diagnosing of extradural abscess are 0.2 to 2.5 cases per 10,000 hospital admission.1
The yearly incidence of spinal epidural abscess has risen in the past 2 - 3 decennary from 0.2 - 1 case per 10,000 infirmary admissions to 2.5 - 3 per 10,000 admission fee . The rising relative incidence of spinal epidural abscess is because of increased cases of endovenous illicit drug function and increased diagnostic or therapeutic spinal procedures . statistical distribution of symptom and house due to spinal epidural abscess depend on location of abscess in neck , mid back and lower back .
