All of the following are true about iliopsoas bursitis and tendonitis EXCEPT which of the following?

Correct Answer: B

Rationale: The correct answer is B because pain with hip extension is not typically associated with iliopsoas bursitis and tendonitis. The iliopsoas muscle is responsible for hip flexion, so pain is usually felt with activities that involve hip flexion. Choices A, C, and D are incorrect because these are commonly associated with iliopsoas bursitis and tendonitis. A: Snapping hip syndrome is related to the iliopsoas tendon moving over the hip joint. C: Pain deep in the groin and radiating to the front of the hip is a common presentation. D: Iliopsoas bursitis and tendonitis can involve inflammation or injury to the tendon, but complete rupture is less common.

Correct Answer: B

Rationale: The correct answer is B: Cremasteric reflex. L2 nerve root compression affects the genitofemoral nerve, leading to loss of the cremasteric reflex. The cremasteric reflex is elicited by stroking the inner thigh, causing the ipsilateral testicle to elevate. This reflex is absent in L2 nerve root compression due to disruption in the sensory or motor pathways. Choices A, C, and D are incorrect as they are associated with different nerve roots and reflexes not affected by L2 compression.

Correct Answer: A

Rationale: The correct answer is A: Intercostobrachial nerve. During a mastectomy, the intercostobrachial nerve is often damaged, leading to postmastectomy pain syndrome. This nerve runs along the chest and upper arm, making it susceptible to injury during the surgery. The suprascapular nerve (B) innervates the shoulder joint, the musculocutaneous nerve (C) innervates the muscles of the anterior arm, and the axillary nerve (D) innervates the deltoid and teres minor muscles, none of which are directly affected during a mastectomy. Thus, these choices are incorrect.

Correct Answer: D

Correct Answer: A

Rationale: The correct answer is A: Marked wrist and finger drop. In Saturday night palsy, there is compression of the radial nerve, leading to weakness of the wrist and finger extensors. This results in the characteristic presentation of wrist and finger drop. Choice B is incorrect as atrophy of the APB is seen in carpal tunnel syndrome. Choice C is incorrect as weak elbow extension is not a typical finding in Saturday night palsy. Choice D is incorrect as painless weakness and atrophy of hand intrinsic muscles are more indicative of ulnar nerve compression.
