NEET-PG 2012 - Orthopaedics PYQs Practice Questions

Q: One of the common fractures that occur during boxing by hitting with a closed fist is:

Bennett's fracture dislocation. ***Bennett's fracture dislocation*** - This is an **intra-articular fracture** of the base of the **first metacarpal**, extending into the carpometacarpal (CMC) joint. - It is frequently caused by axial compression with the thumb in a flexed and adducted position, a common injury mechanism in **punching a hard object** during boxing. *Monteggia fracture dislocation* - This injury involves a fracture of the **proximal ulna** coupled with an **anterior dislocation of the radial head**. - It is typically caused by a direct blow to the forearm or a fall on an outstretched hand with a hyperpronated forearm, not a direct punch. *Galeazzi fracture dislocation* - This involves a fracture of the **distal radius** with an associated **dislocation of the distal radioulnar joint (DRUJ)**. - It results from a fall on an outstretched hand with a hyperpronated forearm, which is not consistent with a boxing injury. *Smith's fracture* - Also known as a **reverse Colles' fracture**, this is a fracture of the **distal radius** with **volar displacement of the distal fragment**. - It typically results from a fall on a flexed wrist or a direct blow to the back of the wrist, not a punching injury.

Q: Which of the following conditions can cause locking of the knee joint?

Loose body in knee joint. ***Loose body in knee joint*** - A **loose body** (e.g., a fragment of cartilage or bone) can get trapped between the articular surfaces of the knee joint, mechanically obstructing its movement and causing sudden, painful **locking**. - This mechanical impingement prevents full extension or flexion of the knee until the loose body shifts, leading to episodic locking symptoms. *Osgood Schlatter* - This condition involves inflammation and potential avulsion of the **tibial tuberosity** where the patellar tendon inserts. - It primarily causes pain and swelling below the kneecap, especially during physical activity, but does not typically result in true mechanical locking of the joint. *Tuberculosis of knee* - **Tuberculosis of the knee joint** is an infectious arthritis that causes chronic pain, swelling, and gradual destruction of articular cartilage and bone. - While it can lead to pain and limited range of motion, it usually does not present with the sudden, intermittent mechanical locking characteristic of a loose body. *a and b both* - Neither **Osgood Schlatter** nor **Tuberculosis of the knee** typically cause the characteristic mechanical locking sensation described for a loose body in the joint. - Each of these conditions has distinct pathophysiological mechanisms and clinical presentations that do not involve a physical obstruction causing locking.

Q: Which of the following is NOT a symptom of carpal tunnel syndrome?

Ulnar nerve dysfunction. ***Ulnar nerve dysfunction*** - Carpal tunnel syndrome specifically involves compression of the **median nerve**, not the ulnar nerve. - Symptoms related to the median nerve include numbness and tingling in the **thumb, index, middle, and radial half of the ring finger**, along with **thenar muscle wasting**. *Tinel sign* - The **Tinel sign** is a common physical examination finding in carpal tunnel syndrome, elicited by tapping over the **median nerve** at the wrist. - A positive sign involves tingling or electric shock-like sensations in the **median nerve distribution**. *Phalen's sign* - **Phalen's sign** is another classic physical maneuver used to diagnose carpal tunnel syndrome, where exaggerated wrist flexion for 60 seconds reproduces symptoms. - This maneuver increases pressure within the **carpal tunnel**, exacerbating median nerve compression. *Pain & paraesthesia of wrist* - **Pain and paraesthesia (numbness and tingling)** in the wrist and hand are hallmark symptoms of carpal tunnel syndrome. - These symptoms are often worse at night or with repetitive hand movements, reflecting **median nerve irritation**.

Q: Apparent lengthening is seen in which stage of TB Hip

Stage III. ***Stage III*** - In **Stage III (destructive stage)** of TB Hip, significant destruction of the femoral head and acetabulum can lead to superior migration of the greater trochanter. - This superior migration results in **apparent lengthening** of the limb due to the loss of bone structure and joint space. *Stage I* - **Stage I (synovitic stage)** involves inflammation of the synovium with effusion, but no significant bone destruction or joint changes that would cause lengthening. - At this stage, the joint space is usually preserved, and **no appreciable limb length discrepancy** is observed. *Stage II* - **Stage II (cartilage and early bone destruction)** begins to show destruction of articular cartilage and subchondral bone. - While there is some destruction, it is generally not extensive enough to cause the characteristic **apparent lengthening** seen in later stages. *None of the options* - This option is incorrect because **apparent lengthening** is a well-recognized feature during the advanced destructive phase (Stage III) of TB Hip. - The progressive nature of the disease directly contributes to specific radiographic and clinical findings like **unstable hip** and subsequent lengthening or shortening.

Q: Heterotopic ossification is primarily associated with which of the following?

Soft tissues. ***Soft tissues*** - **Heterotopic ossification** is the pathological formation of mature, lamellar bone in **non-osseous (soft tissues)** where bone does not normally exist. - This process often occurs in muscles, tendons, ligaments, or fascia, particularly after trauma or neurological injury. *Bone* - Heterotopic ossification is the formation of bone *outside* of normal skeletal structures, not within existing bone. - While it involves bone formation, its defining characteristic is its location in **extraskeletal sites**, not within the bone itself. *Joint* - Although heterotopic ossification can occur around joints, leading to **joint stiffness** and limited range of motion, it is the formation of bone within the **soft tissues surrounding the joint**, not within the joint capsule or articular cartilage itself. - The primary location is the adjacent soft tissue, which then secondarily impacts joint mobility. *None of the options* - This option is incorrect because "Soft tissues" accurately describes the primary location where heterotopic ossification occurs. - The condition is specifically defined by bone formation in these non-skeletal sites.
