Spinal Orthoses Flashcards
Lumbar binders vs corsets
Binders increase intra-abdominal pressure; minimally restrictive
Corsets increase intra-abdominal pressure to reduce axial load; moderately reduces gross movement; 3-point force systems; improved trunk proprioception
Trimlines for thoracolumbar (dorsolumbar) corset.
Superior edge: inferior to spine of scapula
Name 3 conventional LSOs
- Chair back
- Williams
- Knight LSO
Chair back LSO motion control:
Sagittal
Williams LSO motion control:
Extension and coronal
Knight LSO motion control:
Sagittal-coronal
Chair back LSO features:
Thoracic band
Pelvic band
2 Paraspinal bars
Williams LSO features:
Thoracic band
Pelvic band
Lateral bars (mobile to allow flexion ROM)
Knight LSO features:
Thoracic band
Pelvic band
Paraspinal bars
Lateral bars
Conventional LSO, trimlines: pelvic band
Inferior edge at sacrococcygeal junction
Laterally ends anterior to mid-axillarly trochateric line
Conventional LSO, trimlines: thoracic band
24 mm inferior to inferior angle of scapula
Ends laterally anterior to the mid-axillary trochanteric line
Conventional LSO, trimlines: lateral bars
Follow the mid-axillary trochanteric line from the thoracic band to the pelvic band
Conventional LSO, trimlines: paraspinal bars
Follow paraspinal muscles
Connect thoracic and pelvic bands
What are some examples of contemporary LSOs?
Anterior overlap LSO
Prefab/OTS LSO
What are optional modifications that can be made to a LSO? (6)
Trochanter extension Sternal extension Reinforcements Rib gussets Perforations (air flow) High dorsal spine control
