⫸ Which vertebrae is affected in a Jefferson's fracture? What is the treatment? Answer: 1. C1 fracture

  1. HALO ⫸ Name 3 goals for idiopathic scoliosis treatment. Answer: 1. Achieve spinal balance
  2. Prevent curve progression
  3. Reduce curve in-brace by at least 50% ⫸ Which curve of a double spinal curve is more flexible? Answer: Minor curve ⫸ How would you test for "Normal" muscle strength for: Tibialis Posterior? Answer: - Pt is side lying on test side with foot off table
  • Stabilize lower leg proximal to the ankle
  • Pt inverts the foot through full ROM with slight plantarflexion
  • Apply resistance on the medial border of the forefoot ⫸ How would you test for "Normal" muscle strength for: Tibialis Anterior? Answer: - Pt is sitting, ankle is in plantarflexion
  • Support the lower leg and stabilize proximal to the ankle
  • Pt dorsiflexes and inverts foot through full ROM (keeping toes relaxed)
  • Apply resistance on the dorso-medial aspect of the forefoot

⫸ Which curve magnitudes (1) and types (2) are more likely to progress? Answer: 1. Greater than 30 degrees

  1. Single thoracic and double curves ⫸ What rotational prominences will appear during Adam's forward bending test for-
  2. Thoracic curve?
  3. Lumbar curve? Answer: 1. Rib prominence
  4. Paraspinals of lumbar vertebrae ⫸ What is the proper width of the opening for a TLSO or LSO? Answer: 1/2" to 3 1/2" gap or overlap if bivalve ⫸ Describe the lateral trim lines for a LSO? Answer: Superior: Flow from anterior to posterior Inferior: 1/2" to 1" superior to greater trochanter
    • Slightly angled from anterior to posterior ⫸ Where is the Center of Gravity located when standing erect? Answer: Anterior to the edge of S2 vertebrae ⫸ Where is the Center of Gravity located in relation to the following joints? (sagittal plane)
  1. Hip?
  2. Knee?
  3. Ankle? Answer: 1. Posterior to hip (extension moment)
  4. Anterior to knee (extension moment)
  5. Anterior to ankle ⫸ 1. What is the mechanism of injury for a Seat belt fracture?
  6. What is another name for it? Answer: 1. Flexion and distraction
  7. aka "Chance fracture" ⫸ 1. Which spinal orthoses utilize hyperlordosis (2)
  8. Why?
  9. How? Answer: 1. Jewett and Cash
  10. Decreases flexion, which reduces compression on anterior vertebral bodies and limits distraction of posterior elements
  11. Three-point pressure: One force applied anterior and two applied posterior ⫸ What is the most common curve pattern for adolescent idiopathic scoliosis? Answer: Single right thoracic ⫸ 1. What is a Risser sign?
  12. What does it indicate? Answer: 1. Presence of mature growth centers on radiograph of the iliac crests (or the hand)
  13. Indicates likelihood of progression

⫸ Which structures are targeted when testing the knee for SAGITTAL plane stability? (2) Answer: Anterior cruciate ligament (ACL) and Posterior cruciate ligament (PCL) ⫸ 1. What structure is affected in a Hangman's fracture?

  1. What is the treatment if stable?
  2. What is the treatment if unstable? Answer: 1. C2 pedicle
  3. if stable: CTO
  4. if unstable: HALO ⫸ What is AROM? Answer: Active Range of Motion
  • Patient actively moves through the range of motion of that joint ⫸ What is PROM? Answer: Passive Range of Motion
  • Therapist stabilizes proximal joint segments and moves distal segment(s) through full ROM ⫸ Which term describes the inability to generate FORCE when a muscle is in a fully shortened position? Answer: Active insufficiency ⫸ How does an orthosis substitute for ligaments? Answer: Protects the joint against excessive translatory movement ⫸ What lever system are most muscles?
