ARTHREX ARTHROPLASTY ACTUAL EXAM
PAPER 2026 QUESTIONS WITH SOLUTIONS
GRADED A+
◉ Subscapularis Peel-Off. Answer: - least common technique used in a
TSA procedure.
- repairs back through transosmosis bone tunnels.
- bone to tendon healing can be unpredictable
- allows surgeon to medialize the tendon.
◉ Lesser tuberosity Osteonomy. Answer: - Most challenging technique
to manage subscapularis.
- Remove subscapularis with chunk of bone still on
- Provides the strongest repair
- easiest to predict healing process
◉ 2 surgical approaches in the surgical exposure in shoulder
Arthroplasty. Answer: 1) Deltopectoral Approach (common)
. Incision is made from the clavicle to the humeral head
2) Superolateral Approach (uncommon)
.
, ◉ UNIVERS II humeral head sizes. Answer: - range from 40 to 56
going up in increments of 2.
- Sizes: 40/17, 42/17, 44/17, 44/19, 46/18, 46/20, 48/19, 48/21, 50/19,
50/21, 52/20, 52/22, 54/21, 54/23, 56/22, 56/24
◉ version of humerus. Answer: - measured from 0-10 degrees.
◉ heads of humeral implant. Answer: - Made of cobalt chrome (nickel is
used in the preparation of these implants)(NOT recommended for
patients with a true nickel allergy)
◉ Neck/shaft of humeral stem implant. Answer: - ranges from 125-140
degrees of shaft inclination
- variable after implantation
- matching humeral head osteotomy
- +/-10degrees version
- 3.5mm offset
- stems are made of titanium
-newer version of the stems is far easier for removal because of the new
trunion and box geometry.
◉ Humeral Prep Tray. Answer: . Humeral Gold Trials (5-13mm)
. resection protectors 40-45mm
