Rehabilitation of Spine Conditions Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Rehabilitation of Spine Conditions. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Rehabilitation of Spine Conditions Indian Medical PG Question 1: Which of the following is not a typical symptom of a lumbar disc herniation?
- A. Positive straight leg raise test
- B. Saddle anesthesia (Correct Answer)
- C. Radicular leg pain
- D. Weakness in foot dorsiflexion
Rehabilitation of Spine Conditions Explanation: ***Saddle anesthesia***
- While a severe complication, **saddle anesthesia** is indicative of **cauda equina syndrome**, a medical emergency, and not a typical, isolated symptom of a simple lumbar disc herniation.
- It suggests **compression of multiple nerve roots** in the lumbosacral region, beyond what is usually seen with a single disc herniation.
*Positive straight leg raise test*
- This is a common and reliable physical exam finding in patients with **lumbar disc herniation**, indicating nerve root irritation.
- It elicits radiating pain down the leg when the affected leg is raised between 30 and 70 degrees.
*Radicular leg pain*
- **Radicular pain**, often described as sharp, shooting pain down the leg, is the hallmark symptom of a lumbar disc herniation as it signifies **nerve root compression**.
- The pain typically follows a **dermatomal pattern**, corresponding to the specific nerve root involved.
*Weakness in foot dorsiflexion*
- Weakness in **foot dorsiflexion** (commonly affecting the **L4 or L5 nerve roots**) is a frequently observed neurological deficit in lumber disc herniation.
- This can be assessed through manual muscle testing and is a sign of **motor nerve root compression**.
Rehabilitation of Spine Conditions Indian Medical PG Question 2: Which of the following phases are directly involved in the recovery phase of the disaster cycle?
- A. Response and Rehabilitation
- B. Mitigation and Rehabilitation
- C. Response and Preparedness
- D. Rehabilitation and Reconstruction (Correct Answer)
Rehabilitation of Spine Conditions Explanation: ***Rehabilitation and Reconstruction***
- **Rehabilitation** is the short-term recovery phase focusing on restoring essential services, providing temporary shelter, medical care, and supporting affected populations to resume normal activities.
- **Reconstruction** is the long-term recovery phase involving rebuilding damaged infrastructure, permanent housing, economic restoration, and development improvements.
- These two phases together constitute the **recovery phase** of the disaster cycle according to standard disaster management frameworks (WHO, NDMA).
*Mitigation and Rehabilitation*
- While **rehabilitation** is correctly part of recovery, **mitigation** is traditionally considered a separate continuous phase or part of preparedness, focused on reducing future disaster risks.
- **Mitigation** measures are implemented throughout the disaster cycle, not specifically as a direct component of the recovery phase.
*Response and Rehabilitation*
- **Response** refers to immediate life-saving actions during and immediately after a disaster (search and rescue, emergency medical care, evacuation).
- **Response** precedes the recovery phase and is distinct from it, though **rehabilitation** is indeed part of recovery.
*Response and Preparedness*
- **Preparedness** involves planning, training, and resource allocation before a disaster occurs.
- **Response** is the immediate action during/after the disaster.
- Neither constitutes the recovery phase, which follows after the immediate response is complete.
Rehabilitation of Spine Conditions Indian Medical PG Question 3: What is an absolute indication for surgery in disc prolapse?
- A. Recurrent episodes of sciatica
- B. Cauda equina syndrome (Correct Answer)
- C. Pain not relieved by complete rest
- D. Progressive motor weakness despite conservative management
Rehabilitation of Spine Conditions Explanation: ***Cauda equina syndrome***
- **Cauda equina syndrome** is a neurological emergency characterized by compression of the cauda equina nerves, leading to symptoms like **saddle anesthesia**, bowel/bladder dysfunction, and severe neurological deficits, necessitating immediate surgical decompression.
- Delay in surgery for **cauda equina syndrome** can result in permanent neurological damage, making it an *absolute indication* for surgical intervention within **48 hours**.
*Recurrent episodes of sciatica*
- While recurrent **sciatica** can be debilitating and may eventually warrant surgery, it is typically managed conservatively initially and is not considered an *absolute emergency* for surgery.
- Surgical intervention in recurrent **sciatica** is usually considered when conservative treatments fail over 6-12 weeks, but it is a *relative indication*, not an immediate requirement.
*Progressive motor weakness despite conservative management*
- **Progressive motor weakness** is a serious concern and represents a *relative indication* for surgery, especially if documented over serial examinations.
- Unlike **cauda equina syndrome**, which requires immediate surgery, progressive weakness allows for a brief period of conservative management and surgical planning, though surgery should not be unduly delayed if weakness continues to progress.
*Pain not relieved by complete rest*
- **Pain not relieved by rest** is a common symptom of disc prolapse and can be an indication for surgery after failed conservative management, but it is not an *absolute emergency* like **cauda equina syndrome**.
- This type of pain often indicates discogenic pain or nerve root compression but can often be managed with medications, physical therapy, or injections before surgical consideration.
Rehabilitation of Spine Conditions Indian Medical PG Question 4: A patient presents with pain in the back of the thigh and leg after lifting heavy weights. Which spinal segment is most likely involved?
- A. L4
- B. L5
- C. S1 (Correct Answer)
- D. S2
- E. L3
Rehabilitation of Spine Conditions Explanation: ***S1***
- Pain radiating to the **back of the thigh and leg** after lifting heavy weights is the classic presentation of **S1 radiculopathy**, typically from L5-S1 disc herniation.
- The S1 nerve root innervates the **posterior thigh via the sciatic nerve**, continues down the **posterior leg**, and extends to the **lateral foot and little toe**.
- Clinical findings include diminished or absent **Achilles reflex**, weakness of **plantar flexion** (gastrocnemius/soleus), and sensory changes along the posterior leg and lateral foot.
- This is the **most common** presentation of sciatica from heavy lifting.
*L3*
- L3 nerve root involvement typically causes pain in the **anterior and medial thigh** with weakness of **hip flexion and knee extension** (quadriceps).
- The pain pattern does not match the posterior distribution described in this clinical scenario.
*L4*
- L4 radiculopathy presents with pain and numbness in the **medial leg and foot**, weakness of **ankle dorsiflexion** (tibialis anterior), and diminished **patellar reflex**.
- The pain distribution is anteromedial, not posterior as described in this case.
*L5*
- L5 nerve root impingement causes pain radiating to the **lateral calf and dorsum of the foot**, weakness of **great toe extension** (extensor hallucis longus), and **foot drop**.
- While L5 can cause posterior thigh pain, the classic distribution extends laterally down the leg, not primarily posterior.
*S2*
- S2 radiculopathy is uncommon and typically presents with **perineal/perianal pain** and **saddle anesthesia** rather than isolated posterior leg pain.
- S2 contributes to bladder and bowel function; isolated S2 involvement would not present with the classic sciatica pattern described.
Rehabilitation of Spine Conditions Indian Medical PG Question 5: A patient presented with Saddle anaesthesia with bladder and bowel involvement and muscle power is normal. The diagnosis is:
- A. L4-L5 disc prolapsed
- B. L3-L4 root involvement
- C. Conus medullaris lesion (Correct Answer)
- D. Cauda equina syndrome
Rehabilitation of Spine Conditions Explanation: ***Conus medullaris lesion***
- A **conus medullaris lesion** typically presents with **saddle anesthesia**, early and severe **bladder and bowel dysfunction**, and often **symmetrical neurological deficits** [1], [3].
- **Motor weakness in the legs** is usually minimal or absent, which aligns with the patient's normal muscle power in this case.
*L4-L5 disc prolapsed*
- A **L4-L5 disc prolapse** primarily causes **radicular pain** and weakness in the distribution of the L5 nerve root (e.g., foot drop, weakness of ankle dorsiflexion) [2].
- While it can cause some sensory changes, **saddle anesthesia** and severe bladder/bowel dysfunction are not typical features.
*L3-L4 root involvement*
- **L3-L4 root involvement**, often from a disc herniation, would typically present with **quadriceps weakness**, absent patellar reflex, and sensory loss over the medial thigh [2].
- It would not cause **saddle anesthesia** or significant bladder/bowel dysfunction as a primary symptom.
*Cauda equina syndrome*
- **Cauda equina syndrome** presents with **saddle anesthesia** and **bladder/bowel dysfunction**, but it is generally characterized by **significant motor weakness** in the lower extremities (e.g., severe leg weakness, foot drop), which is absent here.
- The onset of bladder and bowel symptoms in cauda equina syndrome is often more gradual and less severe initially compared to conus medullaris lesions.
Rehabilitation of Spine Conditions Indian Medical PG Question 6: Early movement following surgery for ankylosis is
- A. Desirable (Correct Answer)
- B. Harmful
- C. Indicated only when ankylosis is one sided
- D. Unimportant
Rehabilitation of Spine Conditions Explanation: ***Desirable***
- Early movement following surgery for **ankylosis** is crucial for preventing **re-ankylosis** and promoting the formation of a **neocartilage-like layer**.
- It helps maintain joint mobility, reduce stiffness, and improves long-term functional outcomes after procedures like **arthroplasty**.
*Harmful*
- Delays in movement can lead to increased fibrous tissue formation, limiting the newly created joint's mobility and potentially causing **re-ankylosis**.
- Prolonged immobilization after joint surgery can also lead to muscle atrophy, contractures, and impaired circulation, hindering recovery.
*Indicated only when ankylosis is one sided*
- The principle of early movement applies to both **unilateral** and **bilateral ankylosis** to prevent recurrence and improve range of motion in the affected joint(s).
- Focusing solely on unilateral cases overlooks the functional benefits of early mobilization for all patients undergoing such surgery.
*Unimportant*
- Early movement is a **critical component** of postoperative recovery, as it directly impacts the success of the surgical intervention by maintaining joint space and flexibility.
- Neglecting early motion can compromise the surgical outcome, increasing the risk of stiffness, pain, and the need for further interventions.
Rehabilitation of Spine Conditions Indian Medical PG Question 7: Halopelvic traction is primarily used for correcting which specific spinal deformity?
- A. Kyphosis (Correct Answer)
- B. Spondylolisthesis
- C. Scoliosis
- D. Spinal stenosis
Rehabilitation of Spine Conditions Explanation: **Kyphosis**
* **Halopelvic traction** is a technique specifically designed to apply sustained corrective forces to the spine, making it particularly effective in treating severe **kyphosis**, especially in young patients prior to surgical correction.
* It aids in gradually stretching soft tissues and straightening the spinal curvature over time, often used in cases of congenital or severe developmental kyphosis.
*Scoliosis*
* While traction can be used in some spinal deformities, **scoliosis** (lateral curvature) is more commonly treated with **bracing** or **surgical fusion**, as halopelvic traction is less effective in correcting the rotational component.
* Correction of scoliotic curves typically involves forces applied in multiple planes, which halopelvic traction is not ideally suited for.
*Spondylolisthesis*
* **Spondylolisthesis** involves the **slippage of one vertebra over another**, which is primarily managed through **stabilization** to prevent further slippage.
* Halopelvic traction is not indicated as it could potentially exacerbate instability in the presence of vertebral slippage.
*Spinal stenosis*
* **Spinal stenosis** refers to the **narrowing of the spinal canal**, which compresses nerves and is usually treated with **decompressive surgery** or **conservative management** for pain relief.
* Traction methods are generally not used for spinal stenosis as they do not address the underlying anatomical narrowing and may worsen symptoms.
Rehabilitation of Spine Conditions Indian Medical PG Question 8: Holdsworth classification of thoracolumbar spine fracture is based on how many columns of spine?
- A. Five
- B. Four
- C. Three
- D. Two (Correct Answer)
Rehabilitation of Spine Conditions Explanation: ***Two***
- The Holdsworth classification system, developed in 1963, simplifies the spine into two principal columns: the **anterior column** and the posterior column.
- This system primarily focuses on the **stability** of the fracture based on the integrity of these two columns, particularly the posterior ligamentous complex.
*Three*
- The **Denis classification** system, a more widely used and detailed system, divides the spine into **three columns**: anterior, middle, and posterior.
- This three-column model provides a more nuanced understanding of fracture stability and neurological compromise.
*Four*
- While other, more complex classification systems exist for spinal fractures, none are based on exactly four columns.
- The concept of four columns is not a recognized standard in spinal fracture classification.
*Five*
- There is no established spinal fracture classification system that utilizes five columns to describe the injury pattern.
- Such a classification would be overly complex and not clinically practical for rapid assessment.
Rehabilitation of Spine Conditions Indian Medical PG Question 9: Pott's spine is most common at which specific region of the spine?
- A. Sacral
- B. Cervical
- C. Lumbosacral
- D. Thoracolumbar (T12-L1) (Correct Answer)
Rehabilitation of Spine Conditions Explanation: **Thoracolumbar (T12-L1)**
- The **thoracolumbar junction (T12-L1)** is the most common site for Pott's spine due to its biomechanical stress and vascular supply, making it a frequent location for spinal tuberculosis.
- This region is susceptible to **compression fractures** and bone destruction, leading to kyphotic deformity (gibbus) in advanced cases.
*Sacral*
- While spinal tuberculosis can affect any part of the spine, the **sacral region** is considerably less common than the thoracolumbar junction.
- Infections in the sacrum are often associated with other pelvic involvement or direct extension from adjacent sites.
*Cervical*
- Tuberculosis of the **cervical spine** can occur but is not as frequent as in the thoracolumbar region.
- Clinical manifestations can include **neck stiffness, dysphagia**, and neurological deficits affecting the upper limbs.
*Lumbosacral*
- The **lumbosacral region** (L5-S1) can be affected by Pott's spine, but it is less common than the thoracolumbar junction.
- Involvement here can lead to specific neurological symptoms like **foot drop** or radicular pain in the lower extremities.
Rehabilitation of Spine Conditions Indian Medical PG Question 10: Undertaker's fracture is seen at the level of cervical vertebra:
- A. C5-C6
- B. C6-C7 (Correct Answer)
- C. C3-C4
- D. C1-C2
Rehabilitation of Spine Conditions Explanation: **C6-C7**
- An **undertaker's fracture** is a post-mortem injury typically seen in cases of hanging, resulting from the neck's hyperextension.
- It commonly affects the lower cervical spine, most frequently at the **C6-C7 level**, due to the biomechanics of the forces involved.
*C5-C6*
- While cervical fractures can occur at various levels, **C5-C6** is less common for an undertaker's fracture specifically.
- This level is more frequently associated with **cervical spondylosis** or traumatic injuries from falls.
*C3-C4*
- Fractures at the **C3-C4 level** can be life-threatening as they are close to the phrenic nerve origin, but they are not characteristic of "undertaker's fracture."
- Injuries at this level are less common in the specific context of post-mortem hyperextension.
*C1-C2*
- Fractures of **C1 (atlas) and C2 (axis)**, such as a Jefferson fracture or hangman's fracture, are distinct and result from different mechanisms.
- They are not typically referred to as "undertaker's fracture," which implies a specific post-mortem injury pattern.
