Hallux Valgus Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Hallux Valgus. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Hallux Valgus Indian Medical PG Question 1: Genu valgus deformity seen when?
- A. Long axis of tibia n fibula moves medial to long axis of femur
- B. Long axis of femur is anterior to tibia and fibula
- C. Long axis of femur is posterior to tibia and fibula
- D. Long axis of tibia n fibula moves lateral to the long axis of femur (Correct Answer)
Hallux Valgus Explanation: ***Long axis of tibia and fibula moves lateral to the long axis of femur***
- **Genu valgus**, also known as **knock-knees**, is a deformity where the knees angle inward, causing the lower legs to bow outward.
- This alignment means the **long axis of the tibia and fibula (lower leg)** deviates laterally relative to the **long axis of the femur (thigh bone)**, bringing the knees closer together.
*Long axis of tibia and fibula moves medial to long axis of femur*
- This description corresponds to **genu varum**, or **bow-legs**, where the knees bow outward and the ankles are close together.
- In genu varum, the lower leg bones deviate medially relative to the femur.
*Long axis of femur is anterior to tibia and fibula*
- This describes a sagittal plane misalignment, specifically relevant in cases of **knee hyperextension** or **recurvatum**, rather than typical genu valgus.
- Genu valgus primarily involves coronal plane angulation at the knee.
*Long axis of femur is posterior to tibia and fibula*
- This anatomical relationship would imply a severe and unusual flexion deformity or dislocation, which is not characteristic of genu valgus.
- Genu valgus involves a lateral deviation of the distal segment (tibia/fibula) in relation to the proximal segment (femur).
Hallux Valgus Indian Medical PG Question 2: What is the condition commonly known as jumper's knee?
- A. Inflammation of the patellar tendon at its insertion on the patella.
- B. Tendinopathy of the quadriceps tendon.
- C. Injury to the hamstring tendon.
- D. Patellar tendonitis due to overuse of the patellar tendon. (Correct Answer)
Hallux Valgus Explanation: ***Patellar tendonitis due to overuse of the patellar tendon.***
- **Jumper's knee** is the common term for **patellar tendonitis**, which specifically refers to inflammation of the patellar tendon.
- This condition is frequently caused by **overuse**, especially in activities involving repetitive jumping and landing.
*Inflammation of the patellar tendon at its insertion on the patella.*
- While jumper's knee does involve inflammation of the patellar tendon, it is more commonly at its insertion on the **tibial tubercle** or specifically its origin at the **inferior pole of the patella**, not necessarily at the patella itself.
- This option is less precise as it describes only one aspect of the condition without mentioning the critical role of overuse.
*Tendinopathy of the quadriceps tendon.*
- **Tendinopathy of the quadriceps tendon** is a distinct condition affecting the tendon above the patella, known as **quadriceps tendinopathy**.
- It presents with pain proximal to the patella, differentiating it from jumper's knee, which involves the tendon distal to the patella.
*Injury to the hamstring tendon.*
- An **injury to the hamstring tendon** would cause pain and symptoms on the posterior aspect of the knee or thigh.
- This is completely unrelated to jumper's knee, which is characterized by anterior knee pain.
Hallux Valgus Indian Medical PG Question 3: All of the following are described surgical procedures for CTE V except -
- A. Dwyer's osteotomy
- B. Salter's osteotomy (Correct Answer)
- C. Posteromedial soft tissue release
- D. Triple Arthrodesis
Hallux Valgus Explanation: ***Salter's osteotomy***
- **Salter's osteotomy** is a procedure primarily used for treating **developmental dysplasia of the hip (DDH)**, aiming to redirect the acetabulum.
- It is not a described surgical procedure for the correction of **congenital talipes equinovarus (CTEV)**.
*Dwyer's osteotomy*
- **Dwyer's osteotomy** is a surgical procedure performed on the **calcaneus** to correct **hindfoot varus**, typically seen in CTEV.
- It involves removing a wedge of bone from the lateral aspect of the calcaneus.
*Posteromedial soft tissue release*
- This is a common and traditional surgical procedure for correcting severe **CTEV** by addressing the contracted soft tissues on the medial and posterior aspects of the foot.
- It involves releasing structures such as the **tibial tendon**, **flexor digitorum longus**, **flexor hallucis longus**, and the **posterior ankle joint capsule**.
*Triple Arthrodesis*
- **Triple arthrodesis** is a salvage procedure that involves fusing three joints in the foot: the **talonavicular**, **calcaneocuboid**, and **subtalar** joints.
- It is used in older children or adolescents with severe, rigid, or recurrent CTEV, often after failed conservative or primary surgical treatments.
Hallux Valgus Indian Medical PG Question 4: A radiograph is obtained from a child with scoliosis. What is the name of the angle used to measure spinal curvature?
- A. Bohler's Angle
- B. Ferguson's Angle
- C. Cobb's Angle (Correct Answer)
- D. Pauwels' Angle
Hallux Valgus Explanation: **Cobb's Angle**
- **Cobb's angle** is the primary method for measuring the severity of **scoliosis** on radiographs.
- It is measured by drawing lines parallel to the superior endplate of the most tilted superior vertebra and the inferior endplate of the most tilted inferior vertebra of the curve; the angle between these two lines (or their perpendiculars) is the Cobb angle.
*Bohler's Angle*
- **Bohler's angle** is used in the assessment of **calcaneus fractures** and is measured on a lateral foot radiograph.
- A decrease in this angle is indicative of a calcaneal fracture.
*Ferguson's Angle*
- **Ferguson's angle**, also known as the lumbosacral angle, measures the inclination of the sacrum relative to the horizontal in the standing position.
- It is primarily used in the assessment of **spondylolisthesis** and other lumbosacral conditions.
*Pauwels' Angle*
- **Pauwels' angle** is used to classify **femoral neck fractures** based on the angle of the fracture line relative to the horizontal.
- It helps determine the severity and stability of femoral neck fractures, guiding treatment decisions.
Hallux Valgus Indian Medical PG Question 5: A 65-year-old lady presented with a swollen and painful knee. On examination, she was found to have grade III osteoarthritic changes. What is the best course of action?
- A. Conservative management
- B. Total knee replacement (Correct Answer)
- C. Arthroscopic washing
- D. Partial knee replacement
Hallux Valgus Explanation: ***Total knee replacement***
- For **grade III osteoarthritis** in a 65-year-old, a total knee replacement is the most definitive and effective treatment to relieve pain and restore function in a severely damaged joint.
- This procedure addresses widespread cartilage loss and structural changes typical of advanced osteoarthritis.
*Conservative management*
- This approach is typically favored for **mild to moderate osteoarthritis**, involving physical therapy, NSAIDs, and lifestyle modifications.
- For **grade III changes** with significant pain and swelling, conservative measures are unlikely to provide sufficient relief or halt disease progression effectively.
*Arthroscopic washing*
- **Arthroscopic lavage** and debridement are rarely recommended for osteoarthritis as they have not shown sustained benefits for pain or function.
- It is sometimes used for specific mechanical symptoms, but it does not address the underlying cartilage loss and structural damage in severe osteoarthritis.
*Partial knee replacement*
- A **partial knee replacement** is suitable when osteoarthritis is confined to a single compartment of the knee, and the other compartments are healthy.
- Given the indication of "grade III osteoarthritic changes" without specifying a single compartment, a total knee replacement is generally more appropriate for widespread disease.
Hallux Valgus Indian Medical PG Question 6: SAFE strategy is recommended for-
- A. Diabetic retinopathy
- B. Trachoma (Correct Answer)
- C. Glaucoma
- D. Cataract
Hallux Valgus Explanation: ***Trachoma***
* The **SAFE strategy (Surgery, Antibiotics, Facial Cleanliness, Environmental improvement)** is the WHO-recommended public health approach for the elimination of **trachoma**, a chronic eye infection caused by *Chlamydia trachomatis*.
* This comprehensive strategy addresses both active infection and its blinding sequelae, specifically **trichiasis** (in-turned eyelashes) through surgery.
*Diabetic retinopathy*
* Management of diabetic retinopathy primarily involves **blood sugar control, regular ophthalmologic exams, laser photocoagulation, and anti-VEGF injections**, not the SAFE strategy.
* The focus is on preventing and treating retinal damage caused by **diabetes**, which is distinct from infectious causes.
*Glaucoma*
* Glaucoma is characterized by **optic nerve damage** and visual field loss, usually due to elevated intraocular pressure, and is managed with **medication, laser therapy, or surgery (e.g., trabeculectomy)**.
* It is a **neurodegenerative condition**, not an infectious disease, so the SAFE strategy is not applicable.
*Cataract*
* Cataracts involve the **clouding of the natural lens** of the eye, leading to blurred vision, and are primarily treated through **surgical removal of the cloudy lens** and implantation of an artificial intraocular lens.
* This condition is age-related or can be caused by trauma or disease, but it is **not an infection** for which the SAFE strategy would be relevant.
Hallux Valgus Indian Medical PG Question 7: Watson Jones operation is indicated for which condition?
- A. Poliomyelitis
- B. Muscle paralysis
- C. Neglected clubfoot
- D. Chronic ankle instability (Correct Answer)
Hallux Valgus Explanation: **Explanation:**
The **Watson-Jones operation** is a reconstructive surgical procedure used to treat **chronic lateral ankle instability**, typically resulting from recurrent sprains that have led to insufficiency of the **Anterior Talofibular Ligament (ATFL)** and the **Calcaneofibular Ligament (CFL)**.
The procedure is a type of **non-anatomic tenodesis stabilization**. It involves using the **Peroneus Brevis tendon**, which is rerouted through tunnels drilled in the distal fibula and the neck of the talus to functionally replace the damaged lateral ligaments. While it provides significant stability, it is often associated with a decrease in subtalar joint motion.
**Analysis of Options:**
* **Poliomyelitis & Muscle Paralysis:** These conditions often require tendon transfers (like the Jones procedure for great toe clawing) or arthrodesis (like Triple Arthrodesis) to restore balance, but not the Watson-Jones ligament reconstruction.
* **Neglected Clubfoot:** This requires extensive soft tissue releases (Turco’s procedure) or bony procedures (Ilizarov, Triple Arthrodesis, or Dwyer’s osteotomy) depending on the age of the patient.
**High-Yield Clinical Pearls for NEET-PG:**
* **Other Tenodesis Procedures:** Apart from Watson-Jones, the **Evans procedure** and **Chrisman-Snook procedure** also use the Peroneus Brevis for ankle stability.
* **Gold Standard:** The **Broström procedure** (anatomic repair/imbrication of the original ligaments) is now preferred over Watson-Jones as it preserves more normal joint kinematics.
* **Confusing Names:** Do not confuse the **Watson-Jones operation** (ankle) with the **Watson-Jones approach** (anterolateral approach to the hip).
Hallux Valgus Indian Medical PG Question 8: Triple arthrodesis does not involve which of the following joints?
- A. Calcaneocuboid Joint
- B. Talanovicular Joint
- C. Talocalcaneal Joint
- D. Tibiotalar Joint (Correct Answer)
Hallux Valgus Explanation: ### Explanation
**Triple arthrodesis** is a surgical procedure aimed at stabilizing the hindfoot, correcting deformities, and relieving pain caused by arthritis or neuromuscular conditions. The term "triple" refers to the fusion of **three specific joints** of the hindfoot.
#### Why Tibiotalar Joint is the Correct Answer:
The **Tibiotalar joint (Ankle joint)** is responsible for plantarflexion and dorsiflexion. It is **not** part of a triple arthrodesis. Fusing the ankle joint along with the hindfoot joints is termed a "pantalar arthrodesis." In a standard triple arthrodesis, the goal is to preserve ankle motion while stabilizing the joints responsible for inversion and eversion.
#### Analysis of Incorrect Options:
The three joints involved in a triple arthrodesis are:
1. **Talocalcaneal (Subtalar) Joint:** Fusion here stabilizes the primary site of hindfoot inversion and eversion.
2. **Talonavicular Joint:** This is considered the "key" joint of the triple arthrodesis; its fusion significantly limits the motion of the other two joints.
3. **Calcaneocuboid Joint:** Fusion of the lateral column completes the stabilization of the midtarsal (Chopart) joint complex.
---
### High-Yield Clinical Pearls for NEET-PG:
* **Indications:** Most commonly performed for **Rigid Flatfoot**, Talipes Equinovarus (TEV), and neuromuscular imbalances (e.g., Polio, Charcot-Marie-Tooth).
* **Order of Fixation:** The standard sequence for surgical fixation is usually **Talonavicular → Subtalar → Calcaneocuboid**.
* **Impact on Motion:** While it provides excellent stability, it results in the loss of almost all inversion and eversion, placing increased stress on the ankle joint (Tibiotalar joint) over time.
* **Chopart’s Joint:** This consists of the Talonavicular and Calcaneocuboid joints. Triple arthrodesis essentially fuses the Subtalar joint + Chopart’s joint.
Hallux Valgus Indian Medical PG Question 9: Hallux valgus is associated with all of the following except:
- A. An exostosis on the medial side of the head of the first metatarsal (Correct Answer)
- B. A bunion
- C. Osteoarthritis of the metatarsophalangeal joint
- D. Overriding or under-riding of the second toe by the third
Hallux Valgus Explanation: **Explanation:**
The correct answer is **A** because the bony prominence seen in Hallux Valgus is **not a true exostosis** (new bone growth). Instead, it is a **pseudo-exostosis** formed by the medial prominence of the first metatarsal head as it deviates medially (metatarsus primus varus), combined with overlying soft tissue thickening.
**Analysis of Options:**
* **Option A (Correct):** As stated, the "bump" is the displaced metatarsal head itself, not a pathological outgrowth of bone (exostosis). This is a common distractor in orthopedic exams.
* **Option B:** A **bunion** is a classic feature of Hallux Valgus. It consists of the pseudo-exostosis, an inflamed adventitial bursa, and thickened skin on the medial aspect of the first MTP joint.
* **Option C:** Chronic malalignment and lateral subluxation of the great toe lead to abnormal loading and articular cartilage wear, eventually resulting in **secondary osteoarthritis** of the first MTP joint.
* **Option D:** As the hallux deviates laterally, it crowds the lesser toes. This often leads to the **second toe** being displaced (usually overriding the hallux) and subsequent deformities of the **third toe** due to space constraints.
**NEET-PG High-Yield Pearls:**
* **Hallux Valgus Angle (HVA):** Normal is <15°.
* **Intermetatarsal Angle (IMA):** Normal is <9°.
* **Associated Deformity:** Often associated with *Pes Planus* (flat foot) and contracture of the Achilles tendon.
* **Surgery:** Common procedures include **Chevron osteotomy** (for mild cases) and **Lapidus procedure** (for severe cases with hypermobility).
Hallux Valgus Indian Medical PG Question 10: A 32-year-old athlete presents with posterior heel pain. Which of the following could be a differential diagnosis?
- A. Achilles tendinopathy
- B. Tendon rupture
- C. Retrocalcaneal bursitis
- D. All of the above (Correct Answer)
Hallux Valgus Explanation: **Explanation:**
Posterior heel pain in an athlete is a common clinical presentation, typically involving the **Achilles tendon complex** or its associated bursae. The correct answer is **All of the above** because these three conditions share a similar anatomical location and clinical presentation.
1. **Achilles Tendinopathy:** This is the most common cause of posterior heel pain in athletes. It can be *insertional* (at the calcaneal attachment) or *non-insertional* (2–6 cm proximal to the insertion). It presents with localized pain and stiffness that worsens with activity.
2. **Achilles Tendon Rupture:** This is an acute injury, often described by the patient as a "pop" or a feeling of being "kicked in the heel." It results in immediate pain, a palpable gap, and a positive **Thompson (Simmonds) test**.
3. **Retrocalcaneal Bursitis:** This involves inflammation of the bursa located between the anterior aspect of the Achilles tendon and the posterior calcaneus. It is often associated with **Haglund’s deformity** (a prominent posterosuperior calcaneal tuberosity).
**NEET-PG High-Yield Pearls:**
* **Thompson Test:** Squeezing the calf fails to produce plantarflexion; diagnostic for complete Achilles rupture.
* **Haglund’s Triad:** Retrocalcaneal bursitis, Achilles tendinosis, and a prominent calcaneal bursal projection.
* **Imaging:** MRI is the gold standard for soft tissue assessment, though Ultrasound is a cost-effective initial tool for identifying tears or tendinosis.
* **Treatment:** Most chronic tendinopathies respond to eccentric loading exercises, while acute ruptures in athletes may require surgical repair.
