Abstract

Background: Flexor tendon injury is a common kind of
trauma and often challenging injury presented to hand surgeons.
Aim of Study: In this study, we aim to test the influence
of activated PRP injection on the functional outcomes after
repair of both flexor tendons zone II, especially the decline
in gliding resistance through avoidance of adhesion formation.
Patients and Methods: 40 patients with injury of both
Flexor Digitorum Superficialis (FDS) and Flexor Digitorum
Profundus (FDP) tendons zone II were included in this study.
Random distribution of the patients into two groups was done,
according to whether activated PRP is injected or not. Group < br />I: In which 20 patients had activated PRP injection in the
tendon at the site of repair and Group II: It is control group,
in which 20 patients had placebo saline injection. Both groups
were evaluated at 8 weeks, 6 and 12 months postoperatively
as regards: The Range of Motion (ROM), Grip Strength and
Finger Pinch measurements.
Results: Group I showed a better Range of Motion, Grip < br />Strength and Finger Pinch strength of the injured side in
comparison to Group II.
Conclusion: Activated PRP injection improved the functional
outcomes after repair of both FDS and FDP tendons
zone II.
