2021 OITE Res Study Test Review

Question 1

What approach do you use to treat distal tibia nonunions?

Answer 1

Posterolateral

Question 2

What are the metastatic patterns of myxoid liposarcoma?

Answer 2

Retroperitoneal, bony mets, soft tissue (this is unusual compared to other types of sarcoma)

Question 3

SYT-SSX fusion is characteristic of what tumor type?

Answer 3

Synovial Sarcoma

Question 4

Compression at the spinoglenoid notch (SGN) affects what nerve and muscle(s)?

Answer 4

Suprascapular nerve, but specifically branch to the infraspinatus only (versus suprascapular notch affects both supraspinatus and infraspinatus)

Question 5

Compression at the supraspinatus notch affects which nerve and muscles(s)?

Answer 5

Compression of the suprascapular nerve, affecting both supraspinatus and infraspinatus

Question 6

Where does the peroneus longus insert?

Answer 6

plantar aspect of the medial cuneiform and base of the first metatarsal

Question 7

Where does the posterior tibial tendon insert?

Answer 7

plantar and medial aspect of the navicular tubercle

Question 8

Achilles tendon ruptures with a defect of 2 cm or less can be treated how?

Answer 8

Defects up to 2 cm can be treated with mobilization of the proximal stump and direct end-to-end repair.

Question 9

Achilles tendon ruptures between 2 cm and 5 cm can be treated how?

Answer 9

Defects between 2 and 5 cm often require increased mobilization of the proximal stump with a V-Y advancement

Question 10

Achilles tendon ruptures with a defect >5 cm are treated how?

Answer 10

A turndown procedure is used to bridge the gap.

Question 11

What is the treatment for a Schwannoma?

Answer 11

Marginal Resection

Question 12

How is osteosarcoma treated?

Answer 12

Treatment usually includes neoadjuvant chemotherapy followed by wide resection and adjuvant chemotherapy. Chemotherapeutic agents commonly used include doxorubicin, cisplatin, methotrexate, and ifosfamide.

Question 13

A positive Wartenburg sign is caused by weakness of what muscle?

Answer 13

The Wartenberg sign is caused by unopposed action of the ulnar insertion of the extensor digiti quinti (radial nerve innervation).

Question 14

What effect does growing rod surgery have on the pulmonary parameters of children with early onset scoliosis (EOS)?

Answer 14

Forced Vital Capacity

Question 15

What is the posterior lever push maneuver in shoulder scopes?

Answer 15

Manipulating the arm with internal rotation and posterior stress on the humeral head, also known as a posterior lever push maneuver, places the subscapularis tendon on tension and enables visualization of the entire insertion.

Question 16

What is the deep internervous plane of the modified Judet approach to the posterior scapula?

Answer 16

Suprascapular nerve (infraspinatus) and axillary nerve (teres minor)

Question 17

In elbow arthroscopy, what nervous structures are at risk in the proximal anteromedial portal?

Answer 17

Proximal anteromedial portal: Medial antebrachial cutaneous nerve (1 mm), median nerve (12 mm), and ulnar nerve (7 mm but posterior to septum)

Question 18

In elbow arthroscopy, what nervous structures are at risk in the anteromedial portal?

Answer 18

Anteromedial (direct medial) portal: Medial antebrachial cutaneous nerve (1 mm) and median nerve (7 mm)

Question 19

In elbow arthroscopy, what nervous structures are at risk in the proximal anterolateral portal?

Answer 19

Proximal anterolateral portal: Radial nerve (10 mm) and posterior antebrachial cutaneous nerve (0 to 14 mm)

Question 20

In elbow arthroscopy, what nervous structures are at risk with the anterolateral portal?

Answer 20

Anterolateral portal: Posterior interosseous nerve (2 to 10 mm) and posterior antebrachial cutaneous nerve (0 to 20 mm)

Question 21

In elbow arthroscopy, what nervous structures are at risk with the proximal posterolateral portal?

Answer 21

Proximal posterolateral portal: Medial and posterior antebrachial cutaneous nerves (more than 2 cm)
