Study Notes
Lumbopelvic Anatomy and Kinematics
- The presentation covers lumbopelvic anatomy and kinematics
- Adam Squires, PT, DPT, Cert SMT, Cert DN, Board Certified Specialist in Orthopedic Physical Therapy, presented.
Objectives
- Understand the normal anatomy of the lumbopelvic region
- Understand the osteokinematics and arthrokinematics of the lumbopelvic region
- Understand Fryette's laws of coupled motion in the spine
- Demonstrate ability to palpate structures in the lumbopelvic region
Lumbar Spine
- 5 lumbar vertebrae
- Anterior longitudinal ligament
- Posterior longitudinal ligament
- Ligamentum flavum
- Interspinal ligament
- Facet joint orientation varies significantly (half-moon, flat, asymmetric half-moon/flat)
- Intervertebral disc and endplate
Lumbar Spine Muscles
- Includes superficial and deep muscles
- Examples include: erector spinae, hip abductors, hip extensors/rotators, hip flexors, hip adductors
Sacrum/Pelvis
- 5 fused vertebrae
- Coccyx is a collection of fused vertebrae
- Ligaments supporting sacrum/pelvis
- Anterior longitudinal ligament
- Iliolumbar ligament
- Lumbosacral ligament
- Sacrospinous ligament
- Sacrotuberous ligament
- Short posterior sacroiliac ligament
- Long posterior sacroiliac ligament
Pelvis
- Composed of ilium, ischium, and pubis
- Bones of the pelvis: ilium, ischium, pubis
- Pelvic inlet shapes (shapes including gynecoid and android)
Sacral/Pelvic Muscles
- Includes superficial and deep muscles
- Examples include: gluteus medius, gluteus maximus, piriformis, gemellus superior, obturator internus, obturator externus, gemellus inferior, quadratus femoris
Lumbopelvic Nerves
- Lumbar plexus
- Sacral plexus
- Nerves branch from spinal cord to supply the lower limb.
Osteokinematics
- Lumbopelvic Flexion: 40-60 degrees
- Lumbopelvic Extension: 20-35 degrees
- Lumbopelvic Lateral Flexion: 15-20 degrees
- Lumbopelvic Rotation: 3-18 degrees
- Rotation limited by facet joint orientation
- Nutation and Counternutation (sacrum relative movement to ilium)
Innominate Dysfunctions
- Inflare/outflare
- Anterior/posterior rotation
- Upslip/downslip
Sacral Torsions
- Left and Right Oblique Axes
- Superior, Middle, Inferior Transverse Axes
Arthrokinematics
- Facet joint: slides without rotation
- Intervertebral joints: pivot and glide
- Ball bearing
- Closing and opening of facet joints (correlating motions with flexion, extension)
- Sacral nutation and counternutation
Fryette's Laws
- Law #1: Neutral Spine (opposite side bending and rotation)
- Law #2: Non-Neutral Spine (same direction side bending and rotation)
- Law #3: Motion in one direction decreases motion in other directions.
Palpation
- Bony landmarks
- Spinous process
- Top of iliac crest = L4 spinous process
- PSIS
- Sacral base
- S2 spinous process
- Inferior Lateral Angle of sacrum (ILA)
- Ischial tuberosity
- ASIS, AIIS
- Pubic symphysis
- Soft tissues
- Erector spinae
- Hip abductors
- Hip extensors/rotators
- Hip flexors
- Hip adductors
