Thoracic and Lumbar Spine Flashcards
(55 cards)
Thoracic Resting Position
Midway between flexion and extension
Thoracic Closed Packed Postion
Extension- bc facets line up
Thoracic Capsular Pattern
Side flexion and rotation equally limited–> extension
Thoracic Spine Facet Joint
- most rigid part of vertebral column
- ribs, ligs, and muscles
- aligned in a mild kyphosis
- mobile platform for a movement [UE via ST and SC]
Breast Bone (Sternum)
3 sections [manubrium, body and sternum]
Manubriosternal Joint (Sternal Angle)
around the 2nd rib
Xiphosternal Joint
T9 vertebrae
T7 ribs
Xiphoid Process
T9 vertebrae
T6 dermatome
Infrasternal Angle
> 90 deg – tightness in internal obliques
< 90 deg – tightness in external obliques-pull inwards
-Find by palpating inferior attachments on the sternum and look at angle between the 2
Thoracic Spine Bony Palpation- Anterior
Costochondral Junctions
Thoracic Spine Bony Palpation-Posterior
- First Rib [sitting and prone]
- Ribs 2-12
- –Most rounded inferior rib felt anterolatreally is the 10th rib
- –Inferior and posterolateral to that is the tip of rib 11, ending just anterior to mid-axillary line
- –Rib 12, inferior and medial to rib 11, it is about an inch or so below rib 11 about 2 – 4 inches from the spinous process
Rib Angles [Palpation]
- Ribs 2-10
- 1st rib doesn’t posses an angle and 11th and 12th are slight if present
- 3-4 cm lateral to the tips of the transverse process
Costovertebral (CV) Joints
- Ribs and vertebral bodies
- Ribs 1, 10, 11, 12 have one vertebral body articulations
- Ribs 2-9 articulate with the two adjacent vertebrae
Costotransverse (CT) Joints
- Ribs and transverse processes of the same level
- Ribs 1-10
- Ribs 11 and 12 do not have these joints.
Costochondral Joints
- Ribs and costal cartilage
- Ribs 1-7 = True Ribs
- Ribs 8-10 = False Ribs
- Ribs 11 and 12 = Floating
Thoracic Rule of Threes
- T1-3: SP at level with TP
- T4-6: SP are ½ level [thumb width] down than TP
- T7-9: SP are one full level down from TP
- T10-12: Starts to come back up
- –T10: SP is one full level below TP
- –T11: SP is one half level below TP
- –T12: SP is even with TP
External Obliques [OINA]
-O: Ribs 5-12
-I: Iliac Crest, pubis, lineal alba
-In: Lower intercostal, iliohyogastric and ilioinguinal nerve
-A: Bilaterally compress abdomen and flexes the spine
Unilaterally: Ipsilateral side bending, contralateral rotation
External Oblique Palpation
- Supine with knees bent, place hand on left side of abdomen and lower ribs. Ask partner to raise left shoulder to right hip.
- Palpate superiorly to the interdigitations with serratus anterior
Internal Obliques [OINA]
-O: Lateral inguinal lig, middle lip of iliac crest, thoracolumbar fascia
-I: Pubis, inferior border of ribs 9-12, linea alba
-In: Lower 5 thoracic n, 1st lumbar nerve, iliohypogastric and ilioinguinal n.
-A: Bilaterally compress abdomen and flexes the spine
Unilaterally ispilateally flexes and rotates to same side
Internal Obliques Palpation
Palpate between the iliac crest and the umbilicus while partner side bends and rotates to the side you are palpating.
Rectus Abdominis [OINA]
- O: Crest of pubis and pubic tubercle, pubic symphysis
- I: Cartilages of the 5-7 ribs and xiphoid process
- In: Spinal nerves T7-12
- A: Flexes vertebral column, compresses abdomen
Rectus Abdominis Palpation
- Supine with legs bend, locate xiphoid process and ribs just lateral with one hand and superior to pubic crest with other. Palpate between these landmarks while patient attempts to flex and relax their trunk. Attempt to palpate the lateral edge
- Washboard effect is the transverse fibrous intersections
Transverse Abdominis [OINA]
- O: Lateral 3rd of inguinal ligament, inner lip of iliac crest, inner cartilage of the lower six ribs, thoracolumbar fascia, and interdigitating with diaphragm
- I: Ends in aponeruosis, front and back of rectus sheath to linea alba and pubis
- In: Lower sic thoracic n, first lumbar n, iliohypgastic and ilioinguinal n.
- A: Compresses abdominal viserca and tenses abdominal wall
Transverse Abdominis
Palpation
Palpating medial to ASIS, ask patient to gently contract after exhaling by bringing belly button into spine. No tilting nor too forceful of a contraction
**most ab exercises target this muscle
