BITER™
A Compact System for Safe Biceps Tenodesis
BITER™
One Hand Grip to Success
Introduction
Biceps tenodesis is a surgical procedure in which the biceps tendon is arthroscopically
transected (biceps tenotomy) and subsequently fixated with an anchor. To perform this
procedure in a straightforward and atraumatic way, a unique instrument was developed for
easy and safe biceps tenotomy – the BITER™ (BIcepsTEndonReleaser).

Product Description
The BITER™ was specially developed for arthroscopic biceps tenotomy.
The instrument can safely grasp and cut the biceps tendon at the same time, preventing the
tendon from slipping during transection.
The BITER™ also enables terminal cutting (as far as the glenoid) which results in minimal
tendon residue in the joint. Fixation of the biceps tendon with the knotless POWERLOCK
PEEK anchor offers a high degree of safety due to its high pull-out strength.
Special Features:
• Combined cutting and grasping instrument
• Anatomic design for optimal use
• Separate versions are available for the left and right shoulders
• No subsequent resection of the biceps tendon required due to terminal cutting
• Fine serration of the jaw prevents the biceps tendon from slipping
• A pin inside the jaw ensures secure grasping of the biceps tendon
• BITER™ can also be used in open surgery

Example of use

Step 1
The arthroscopic procedure is
performed using the 3-portal
technique:
1) Posterior portal
2) Anterolateral portal
3) Anteroinferior portal

Fig. 5
Step 2
The tendon is pulled into the joint
with a palpation hook. This makes
it easier to create an anterolateral
portal in the case of intact interval
structures. The portal is widened to
approx. 1.5 cm (Figs. 4 and 5).

Step 3
The BITER™ in closed position is
introduced via a 1.5 cm incision and
passed through the anterolateral
portal (Fig. 6).
Subsequently, the biceps tendon is
threaded (Fig. 7) and the BITERTM is
advanced as far as the biceps tendon
insertion (Fig. 8)

Step 4
The biceps tendon is detached with
the BITERTM, removed from the joint
and the degeneratively changed part
is resected (Figs. 9 and 10).
The end of the biceps tendon is
armed with a baseball stitch suture
(Fig. 11).

Step 5
After the bone is freshened up with
a burr and the anchor insertion is
prepared with a bone punch, fixation
of the biceps tendon is performed.
The knotless POWERLOCK PEEK
anchor is inserted in the joint with a
rotating motion (Fig. 12). In this way,
the anchor fixates the biceps tendon
in an epiosseous manner.
Any protruding suture material is cut
off (Fig. 13).
Fixation of the biceps tendon with the
POWERLOCK PEEK anchor offers a
high degree of safety due to its high
pull-out strength (Fig. 14).
