Injectable ibuprofen: preliminary evaluation of its ability to decrease peritendinous adhesions.

Area of Science:

• Orthopedic surgery
• Regenerative medicine
• Pharmacology

Background:

• Peritendinous adhesions frequently impair hand function after flexor tendon repair.
• Previous research in rabbits indicated ibuprofen's efficacy in reducing intra-abdominal adhesions.

Purpose of the Study:

• To investigate the potential of ibuprofen to mitigate peritendinous adhesions following flexor tendon repair.
• To assess the impact of localized ibuprofen injection on functional recovery in primate models.

Main Methods:

• Flexor tendon repair was performed in a primate model.
• Ibuprofen was administered via injection directly at the site of tendon repair.
• Adhesion formation and its impact on tendon function were evaluated.

Main Results:

• Injected ibuprofen significantly decreased the development of restrictive peritendinous adhesions.
• The reduction in adhesions correlated with improved functional outcomes for the repaired tendons.

Conclusions:

• Localized ibuprofen injection is a promising strategy for reducing adhesions after flexor tendon repair.
• This approach holds potential for enhancing hand function recovery in patients.
