| hernial sac | The peritoneal envelope of a hernia. (05 Mar 2000) |

| herniate | <anatomy, surgery> The abnormal protrusion herniation of an organ or part of an organ, through an aperture in the surrounding structures. This commonly occurs with the protrusion of an abdominal organ through a defect in the abdominal wall. Examples include inguinal hernia, femoral hernia and umbilical hernia. (27 Sep 1997) |
| herniated | Denoting any structure protruded through a hernial opening. (05 Mar 2000) |
| herniated disk | <orthopaedics> A condition that results in the abnormal protrusion (bulging), herniation or prolapse of a vertebral disc from its normal position in the vertebral column. The displaced disc may exert force on a nearby nerve root causing the typical neurologic symptoms of radiating pain (to an extremity), numbness, tingling and weakness. Recurrent episodes of severe back pain are common. Treatment includes non-steroidal anti-inflammatories, corticosteroids and rest. More advanced cases may require surgical intervention (for example laminectomy, micro-disc surgery). (27 Sep 1997) |
| herniated nucleus pulposus | <orthopaedics> A herniated intervertebral disk (nucleus pulposus) is one which has become displaced (prolapsed) from its normal position in between the vertebral bodies of the spine. Herniated disks often impinge on nearby nerve structures resulting in pain and neurologic symptoms. A clinical situation where the radicular nerve (nerve root) is compressed by the prolapsed disk is referred to as a radiculopathy. This problem tends to occur most commonly in the cervical and lumbar spine. (27 Sep 1997) |
| herniation | <anatomy> Bulging of tissue through an opening in a membrane, muscle or bone. (16 Dec 1997) |
| herniation of nucleus pulposus | <radiology> Focal protrusion of disc material secondary to rupture of annulus fibrosus confined within the posterior longitudinal ligament location: L4/5 (35%); L5/S1 (27%); L3/4 (19%); L2/3 (14%); L1/2 (5%); thoracic spine affected in 3:1000 disc operations, posterolateral (49%): weakest point (posterior longitudinal ligament tightly adherent to posterior margin of disc), posterocentral (8%), lateral/foraminal (less than10%), intraosseous/vertical (14%): Schmorl node, extraforaminal/anterior (29%): commonly overlooked, bilateral: on both sided of the posterior ligament findings: disc (low T1) displaces posterior ligament/epidural fat (high T1), enlarged (edematous) nerve root: trumpet sign, see: degenerative disc disease extradural mass (12 Dec 1998) |

| herniopuncture | Insertion of a hollow needle into a hernia in order to reduce the size of the tumour by withdrawing gas or liquid. (05 Mar 2000) |
| herniorrhaphy | <surgery> The surgical repair of a hernia. This surgery can be done under local or general anaesthesia. May be performed using a conventional incision or using a fibreoptic laparoscope. (27 Sep 1997) |
