Peradaban dibentuk oleh pikiran dan tangan-tangan yang terampil. Keterampilan tangan pada intinya merupakan kompleksitas dari gerakan fleksi pada tangan dan jari-jari. Perlukaan pada tendon flexor akan sangat mempengaruhi keterampilan seseorang dalam melakukan pekerjaannya. Dengan demikian, rekonstruksi yang optimal pada perlukaan tendon flexor tangan sangat diharapkan.

ing flexor tendon injuries. When the flexor tendon is tran·
sected, the finger will have impaired flexion. Pain may limit
the utility of this exercise and other examination maneuvers
are required. Flexor tendon lacerations can be identified by
observing a loss ofnormalfinger cascade. Injuries to theflexor
tendons can also be suggested by loss of tenodesis effect with
passive wrist extension and flexion. Another useful technique
to evaluate integrity of the flexor tendons can be compressing
the distal forearm that normally brings the fingers into the
flexed posture.
Diagnostic studies are occasionally helpful. Plain radio-
graphs, magnetic resonance imaging, or ultrasound may
help detect the location of the proximal tendon after closed
zone 1 injuries Gersey finger injury). Knowing the location of
the proximal tendon also assists in management. When the
Flexor Digitorum Profundis (FDP) retracts to the palm (Leddy
type 1), the tendon must be repaired within 2 weeks. When
retracted to the PIP joint, the repair must be performed within
6 weeks (Leddy type 2). When caught at A4 pulley (Leddy
type 3}, the repair can be performed at any time.s Fullness and
tenderness at these locations, ifpresent, direct management of
jersey finger injuries making diagnostic studies unnecessary.
The presence ofneurovascular injuries should also be assessed
for open lacerations at any level.
Partial tendon injuries are suggested in patients with pain
on resisted flexion. On exploration, if the injury is more than
60% of the tendon in diameter, it should be repaired. If the
injury is less than 60% oftendon diameter, the free edges are
debrided to prevent catching on the pulleys.'
TREAT!ffiNT
Ideal flexor tendon repairs are strong and smooth. Strength
allows for early active motion to prevent adhesion forma-
tion. Repairs should be strong enough to resist gap forma·
tion, which can be a site for adhesion formation or repair
rupture. Repair techniques should also be smooth and not
bunched to facilitate gliding of the tendons around adjacent
structures such as pulleys or other tendons. Repairing flexor
to the strength ofthe repair.
Recently, the modified Becker technique (MGH,
Massachusetts General Hospital) has gained popularity
for its strength, resistance to gap formation, and endurance
with active range of motion therapy.'-11 The MGH tech-
nique is like the Becker repair as it involves placement of
four strands through the core in a criss-cross configuration13
(Figures 77.3A-B). However, the MGH is different in that the
core sutures are 3-0 instead of 6-0 and includes augmentation
with an epitenon suture and avoids the step-cut bevel.

If both these maneuvers do not work, the method described by Sourmelis and
McGrouther should be tried. A chevron incision is made in the distal palm
proximal to the A1 pulley.The flexor tendons are identified. If they are still within
the A1/A2 pulley, they are not disturbed. A 5/6 French pediatric feeding tube is
passed from retrograde through the flexor sheath to emerge at the proximal
incision. The feeding tube is sutured to the palmar surface of the flexor tendon
without withdrawing the tendons from the fibrous flexor sheath. If the tendon
ends have retracted proximal to the A1 pulley, the feeding tube is sutured to
the end of the tendons. Using a combination of pulling the feeding tube at the
distal incision and pushing the flexor tendon at the proximal incision,the tendon
ends are delivered into laceration (Fig. 8-11).
After retrieval to the site of repair, the tendon should be secured in place with
a hypodermic needle to prevent it from retracting proximally and to allow a
tension-free repair.

Next a modified Kessler core suture is placed in the standard manner (Fig. 8-14).
The transverse portion of the suture is locked. It is important to remember that
3-0 Ethibond is a braided suture and does not glide well within the tendon
substance. One should therefore pull the required length of the suture through
the tendon at first pass.A minimum of 0.7 cm, and most commonly 1 to 1.2 cm,
of the tendon is grasped by the longitudinal portion of the suture loop before
making the transverse portion.
A horizontal mattress suture is placed within the previous suture repair using
4-0 Ethibond. Approximately 0.5 to 0.6 cm of the tendon is grapsed by the
longitudinal portion of the suture loop before making the transverse portion
(Fig. 8-15).
The palmar half of the epitendonous repair is now completed (Fig. 8-16).

Background: To propose a new term (‘construct efficiency’) for the evaluation of multi strands flexor tendon repairs using differ-

Studi in vitro: benang braided polyblend lebih superior dibandingkan
dengan benang nilon dalam hal kekuatan. Kekuatan 4 strand dan 6
strand tidak berbeda signifikan dalam hal kekuatan.

Selain jumlah strand, tipe jahitan, dan ukuran benang, asimetri juga
menentukan kekuatan repair dan pencegahan timbulnya gap. Fibrin glue
sama baiknya dengan jahitan epitenon dengan gliding yang lebih baik.

Tendon healing is a complex process that must coordinate healing within the tendon while limiting
the amount of fibrosis in the surrounding tissues.
The ultimate goal of surgical intervention has remained constant: to achieve enough strength to
allow early motion, to prevent adhesions within the tendon sheath, and to restore the finger to
normal range of motion and function.

• Adhesi

– Early mobilization
– Imobilisasi dengan gips meningkatkan risiko
