Ultrasound-Guided Saline Injections to Prevent Tendon Scar After Finger Tendon Repair

Official title: A Prospective Randomized Controlled Trial of Ultrasound-Guided Repeated Normal Saline Injections for Preventing and Treating Tendon Adhesion

Run by Shanghai 6th People's Hospital · NCT07861568 · Data updated 2026-11-12

In adults with zone II flexor tendon injuries in the fingers, researchers will test whether adding ultrasound-guided saline injections after surgery helps prevent or reduce scar tissue and improve movement.

Is this trial a fit for you?

Likely a good fit

Adults 18–60 years with a Zone II flexor tendon rupture scheduled for repair.

Probably not a fit

Patients who do not respond to rehabilitation alone or who have conditions affecting healing may see no added benefit from injections.

What this trial studies

This is a prospective, single-center randomized trial enrolling 80 adults aged 18–60 undergoing zone II flexor tendon repair. Participants are assigned 1:1 to receive standard postoperative rehabilitation with or without ultrasound-guided injections of 1 mL normal saline at the adhesion site on days 7, 14, and 21. Dynamic ultrasound will track saline distribution, and follow-up visits occur at 6 weeks and 3 months to measure total active motion in the repaired digits. The primary outcome is TAM at 3 months, analyzed as a continuous measure. Safety monitoring will assess adverse events related to injections.

Why it matters

Potential benefit: If successful, the saline injections could help reduce tendon adhesions and improve finger movement after repair.

How similar studies have gone: Previous studies in other tendon repairs suggest that localized injections can influence scar formation, but this approach is exploratory for Zone II flexor tendons.
