SECTION 1: MARS ACDF RETRACTOR SYSTEM (Questions 1-
10)
Question 1: What lengths do the blades come in for the MARS ACDF retractor?
A) 15mm and 20mm
B) 30mm to 70mm
C) 35mm to 100mm
D) 10mm to 50mm
Answer: B) 30mm to 70mm
Rationale: The MARS ACDF retractor blades are available in lengths ranging from 30mm
to 70mm. The MARS system has a small, sleek stainless steel body with side-loading
radiolucent titanium blades, and the wide range of blade offerings is designed to adapt to
patient anatomy for intraoperative versatility .
Question 2: How are the blades held in place in the retractor?
A) Vice Mechanism
B) Spring-Loaded Lock
C) Tension from the tissue
D) Magnetic attachment
,Answer: C) Tension from the tissue
Rationale: The blades are held in place by tension from the surrounding tissue, which
provides stable retraction during ACDF procedures. The MARS system provides a rigid
connection between the blade and blade handle, preventing rotation and allowing for an
easy transition to the retractor frame .
Question 3: What sets are required for a case using the Table Arm with the MARS
system?
A) ACDF Retractor Set (9138.9001)
B) MARS Instruments II (932.902)
C) Both 1 & 2
D) Neither 1 nor 2
Answer: C) Both 1 & 2
Rationale: Both the ACDF Retractor Set (9138.9001) and MARS Instruments II (932.902)
are required when using the Table Arm for ACDF cases. The table arm attachment secures
the frame and prevents shifting during the procedure .
Question 4: What material are the MARS ACDF retractor blades made of?
A) Aluminum
B) Titanium
C) Stainless Steel
D) Cobalt-Chromium
Answer: B) Titanium
Rationale: The MARS ACDF retractor blades are made of titanium, which provides
strength, biocompatibility, and MRI compatibility. The blades are described as "radiolucent
titanium blades" by Globus Medical .
,Question 5: The MARS ACDF Retractor Set (9138.9001) contains all of the following,
EXCEPT:
A) Blades
B) Retractor Frame
C) Depth Gauge
D) Distractor
Answer: D) Distractor
Rationale: The MARS ACDF Retractor Set contains blades, retractor frame, and depth
gauge, but the distractor is not included in this set. The distractor is a separate instrument
used for disc space preparation .

with side-loading radiolucent titanium blades. This statement is:
A) True
B) False
Answer: A) True
Rationale: According to Globus Medical product documentation, the MARS ACDF Cervical
Retractor has a small, sleek stainless steel body with side-loading radiolucent titanium
blades .
Question 7: The table arm attachment on the MARS system secures the frame and
prevents shifting. This statement is:
A) True
B) False
Answer: A) True
Rationale: The table arm attachment provides a stable platform by securing the frame and
preventing shifting during the surgical procedure .
, Question 8: The MARS system offers a comprehensive blade offering for minimal soft
tissue disruption and maximum access through a minimal incision. This statement is:
A) True
B) False
Answer: A) True
Rationale: The MARS system is designed for MIS (Minimally Invasive Surgery) access with a
comprehensive blade offering that provides minimal soft tissue disruption and maximum
access through a minimal incision .
Question 9: The MARS ACDF Retractor blades are available in what minimum length?
A) 15mm
B) 20mm
C) 30mm
D) 35mm
Answer: C) 30mm
Rationale: The blades in the MARS system are available in lengths starting from 30mm up
to 70mm .
Question 10: The MARS ACDF Retractor blades are available in what maximum length?
A) 50mm
B) 60mm
C) 70mm
D) 100mm
Answer: C) 70mm
Rationale: The blades in the MARS system are available in lengths up to 70mm .
