Back Pain Question and Answers — Questions and Answers
Question 1: A 15-year-old female elite gymnast with low back discomfort who began experiencing symptoms slowly over the past few weeks arrives at your clinic. She disputes any recent wounds. <br> <br> You observe that she has a hyperlordotic posture during a physical examination. Her hamstrings are so tight that she can't touch her toes. Her single-leg extension test was successful. Spondylolysis is the diagnosis you offer her. <br> <br> Which of the ensuing assertions concerning spondylolysis is true?
- The condition is connected to degenerative pars interarticularis alterations. (Correct answer)
- The disorder usually requires surgical intervention
- The disorder most commonly occurs at the L1-L2 vertebral interface.
- The disorder may present at birth.
Correct answer: The condition is connected to degenerative pars interarticularis alterations.
Spondylolysis is a stress fracture of the pars interarticularis, a small segment of bone in the vertebra, often seen in young athletes due to repetitive hyperextension. This condition represents a degenerative alteration in the bone structure, leading to a defect. It is not typically congenital, rarely requires surgery, and most commonly occurs at the L5-S1 level.
Question 2: A 55-year-old woman arrives at your office and claims that she has been experiencing low back discomfort for three days as a result of falling on the ice. <br> <br> During her physical examination, the lumbar paravertebral muscles on both sides of her show soft tissue soreness and spasm. Her deep tendon reflexes and lower extremity exams are both within normal ranges. <br> <br> Which of the following treatments for her injuries would be an acceptable first-line pharmacologic management?
- NSAIDs or skeletal muscle relaxants. (Correct answer)
- Tramadol or duloxetine.
- Opioid analgesics for 3 days, then nonsteroidal anti-inflammatory drugs (NSAIDs), as needed.
- Prednisone 20 mg/d for 14 days.
Correct answer: NSAIDs or skeletal muscle relaxants.
For acute, uncomplicated low back pain resulting from a fall, NSAIDs (nonsteroidal anti-inflammatory drugs) or skeletal muscle relaxants are considered appropriate first-line pharmacologic treatments. These medications help manage pain and reduce muscle spasms. Opioids are generally avoided due to their risks, and long-term steroids are not indicated for this type of acute injury.
Question 3: When passively extending the quadriceps while the client is lying on the ground, severe low back pain indicates an issue with the:
- Tight quadriceps muscles
- Right C5-C6 nerve root compression was the source of the injury.
- Low back muscles
- L3 nerve root compression (Correct answer)
Correct answer: L3 nerve root compression
Severe low back pain when passively extending the quadriceps (a positive femoral nerve stretch test) indicates an issue with the L3 nerve root compression. The femoral nerve, which innervates the quadriceps, originates primarily from the L2, L3, and L4 nerve roots. Stretching this nerve can elicit pain if these roots are compressed or irritated.
Question 4: After falling from a ladder at work the day before, a 50-year-old house painter shows up to your office. He claims that as the top of a 10-foot ladder started to slide towards the wall, he jumped off and came to rest on his feet. Despite taking ibuprofen and using a heating pad, he experienced rapid onset mid-back pain that is still present today. He claims that no pain is traveling to his legs. <br> <br> Upon physical examination, you discover point soreness at the level of T10 with intact neurologic function both at and below that level. A compression fracture of the T10 vertebral body is seen on the plain films that you ordered. <br> <br> Regarding the treatment of this injury, which of the following assertions is true?
- Therapeutic management includes use of calcitonin
- The diagnostic process includes checking for primary cancers that have spread to the bone.
- You need to rule out osteoporosis.
- An x-ray showing rotation would show that the fracture is unstable. (Correct answer)
Correct answer: An x-ray showing rotation would show that the fracture is unstable.
For a T10 vertebral compression fracture, an X-ray showing rotation would indicate that the fracture is unstable. Instability is a critical factor in determining the course of treatment, as it suggests a higher risk of neurological compromise or further collapse. Stable fractures can often be managed conservatively, while unstable ones may require more aggressive intervention.
Question 5: A 25-year-old man who has been employed to work at a nearby lumber supply company comes to your clinic for a physical. He is anxious despite being thrilled about his new employment choice because some of his buddies have suffered back ailments while working at the business. What can he do to prevent harm to his back, he enquires. <br> <br> Which of the following suggestions may you provide him based on the US Preventive Services Task Force's (USPSTF) recommendations?
- It has been demonstrated that educational initiatives at work have considerable, long-term advantages for back health.
- Although not always helpful in preventing back problems, healthy lifestyle choices like regular exercise and quitting smoking can have a positive impact on one's general health. (Correct answer)
- Lumbar supports are useful in preventing back injuries
- Back schools are useful for primary prevention of back injuries.
Correct answer: Although not always helpful in preventing back problems, healthy lifestyle choices like regular exercise and quitting smoking can have a positive impact on one's general health.
Based on USPSTF recommendations, specific interventions like back belts or back schools have not consistently demonstrated significant, long-term benefits for primary prevention of back pain in asymptomatic adults. However, promoting healthy lifestyle choices such as regular exercise and quitting smoking is always beneficial for overall health and can indirectly support musculoskeletal well-being, even if not directly proven to prevent specific back injuries.
Question 6: What is the most likely source of pain on the left side of the genitalia when side-flexing to the right?
- An iliolumbar ligament sprain (Correct answer)
- An adductor strain
- Sacrotuberous ligament sprain
- A urilogical problem
Correct answer: An iliolumbar ligament sprain
Pain on the left side of the genitalia when side-flexing to the right is most likely caused by an iliolumbar ligament sprain. Side-flexing to the right places the left iliolumbar ligament under stretch. This ligament connects the L5 vertebra to the ilium, and irritation or sprain can refer pain to the groin or genital region due to shared nerve pathways.
Question 7: Which nerve root or roots are responsible if the psoas is weak when tested?
- L4
- L5
- L2 and L3 (Correct answer)
- L4 and L5
Correct answer: L2 and L3
Weakness in the psoas muscle when tested indicates an issue with the L2 and L3 nerve roots. The psoas muscle, a primary hip flexor, is innervated by the femoral nerve, which receives its nerve supply predominantly from the L2, L3, and L4 spinal nerve roots. Therefore, compromise at these levels can manifest as psoas weakness.
