Which muscle/tendon can be incised (1-1.5cm) to help exposure
during TSA? -
ANSWER-pec
major
Which nerve innervates the deltoid muscle? - ANSWER-axillary
Which blood vessel is found at the deltopectoral interval? -
ANSWER-cephalic
vein
What is the average humeral retroversion that is reproduced
during aTSA? -
ANSWER-30
deg
When compared to the size of the corresponding broach, how
much press-fit
,coating is on the Univers II, Apex and Revers stems? -
ANSWER-1.5 mm
depth of ream does NOT - ANSWER-equal max depth of ream
Explain the "love at first bite" principle when discussing
humeral broaching during a Univers II or Apex TSA. - ANSWER-
Love at first bite is used to determine the proper broach/stem
size for the humeral implant. Because the implant has a press
fit of 1.5mm, the surgeon should not increase broach size after
rotational stability is achieved with the broach. Increasing
broach size can result in humeral shaft fracture.
Is broaching larger than "love at first bite" recommended? Why
or why not?️ - ANSWER-Broaching larger than "love at first
bite" is not recommended. Because of the 1.5mm press-fit
coating on our TSA stems, broaching with an inappropriately
large broach can fracture the humeral shaft.
The the 3 key in-situ adjustable features of the Univers II/Apex
humeral systems
- ANSWER-Inclination
(125-140)
Version (+/-) 10
degrees
, Eccentricity (3.5mm eccentric
option)
The posterior offset humeral cup reamer in the Univers Revers
instrument set
adds how much offset compared to the neutral humeral cup
reaming pin? -
ANSWER-2mm or 2mm
anterior
Explain scapular notching and what can be done with the
Univers Revers 135 and 155 choices to minimize it. - ANSWER-
Scapular notching occurs when the humeral head repeatedly
collides with the inferior portion of the glenoibony osteolysis
and poly breakdown.
135 = Lateralizes the implant
155 = eccentric heads
What anatomic landmarks provide the boarders for the
exposure field in a TSA?
- ANSWER-Inferior = 3 sisters
Superior = rotator interval
Medial = conjoin tendons
Lateral = long bead of biceps
