Question | Answer |
---|---|
Difference between the 7 true ribs and the 5 false ribs? | The true ribs articulate to sternum, false ribs to the costal cartilage above them. |
Two main problems in the chest are because of? | Mesoderm Migration or Differentiation of the cells. |
Sternum is made up of what parts? | Ribs, sternal bars, clavicles. |
Pectus Excavatum | Seen in Coffin Lowry syndrome. Surgical procedure to fix. |
Pectus Carinatum | Pidgin Breast. Seen in Homocystinuria. Surgical or breast plate. |
Shield chest | Turner syndrome. |
Fused/Bifid ribs | Gorlin Syndrome. |
Scoliosis | Deformation. |
Dysplaisas of Chest | Cleidocranial dysostosis, many bone dysplasias and mucopolysaccharidoses. |
Malformations (most common) of Chest | Poland syndrome - absent pectoralis major muscle. Beaded ribs and Short sternum, Cleft sternum, Ectopia Cordis. |
Diastasis Recti | The abs aren't connected so there is a gap which will bulge when the child cries or strains. |
Umbilical Hernia | Herniation of the intestines into the umbilicus. |
Ventral Hernia | Lateral herniation to the midline |
2 vessel cord | Single Umbilical artery, 1% of newborns |
Deformations of the Abdomen | Long Cord, Short Cord, Umbilical cord knot. |
Disruptions of the Abdomen | Absence of abdominal muscle - Prune Belly |
Dysplasias of the Abdomen | Hepatosplenomegaly, Shrunken liver. Size/consistency of liver and spleen. |
Malformations of the Abdomen | Omphalocele, Hernia into the umbilical cord, Gastroschesis. Situs Inversus, Meckel's diverticulum, Urachus, Inguinal Hernias. |
Situs Inversus | Major organs are reversed/mirrored. Totalis - Heart on right side Abdominus - Only organs below diaphragm are reversed. |
Meckel's diverticulum | Remnant of the vitelline duct or yolk stalk |
Urachus | Urachal sinus - Dilation into the bladder or at the umbilicus Urachal cyst - remnant of epithelial liniing of urachus Urachal Fistula - no closure. |
Kyphosis | Convex curvature. Spine is bowed out making a hump. |
Lordosis | Concave curvature. Achondroplasia. |
Scoliosis | Lateral curvature |
Minor variants of the Back | Trunk length, Lumbar Lordosis, Bifid Spinous (C2-C3, Sacral dimples, Pigmentation, Hair |
Deformations of the Back | Scoliosis, Gibbus, Platyspondyly, Winged scapulas, Unusual protrusion |
Malformations of the Back | Scoliosis, Scapular abnormalities, Hypoplastic scapulas, Pilonidal dimple tethered cord, Arnold Chiari, Lipomas, sacrococcygeal teratoma, Spinal dysraphism - Spina bifida occulta, Meningocele, Myelomenigocele, spinal rachischisis. |
Arnold-Chiari malformation | can be caused by tethered cord, Herniation of the cerebellum through the foramen magnum |
Spina bifida occulta | mildest form, marked by lipoma, hemangioma, hairy patch. |
Meningocele | Spinal membranes protrude through spinal canal, lower lumbar or sacral. |
Myelomenigocle | Most serious form of spina bifida. Problems with movement and sensation below the level of defect. |
Spinal rachischisis | Failure of fusion of a large part of neural tube, anencephaly iniencephaly. |
