Ultrasound-Guided Repeated Saline Injections to Prevent and Treat Tendon Adhesions After Hand Tendon Repair

Scar tissue can form around a repaired tendon and restrict finger movement. This study will evaluate whether repeated ultrasound-guided normal saline injections, in addition to standard postoperative rehabilitation, can help prevent and treat tendon adhesion after surgical repair of zone II flexor tendon injuries. The study is a prospective, single-center, randomized controlled trial involving 80 adults aged 18 to 60 years with a zone II flexor tendon rupture in the index, middle, ring, or little finger. Participants will be assigned to one of two groups, with 40 participants in each group. Participants in both groups will receive the same standard postoperative rehabilitation treatment, including early active finger mobilization. In addition to this rehabilitation, the experimental group will receive ultrasound-guided percutaneous injections of 1 mL of normal saline at the tendon adhesion site on postoperative days 7, 14, and 21. The control group will receive standard postoperative rehabilitation alone, without postoperative normal saline injections. The primary outcome is total active motion of the repaired finger at 3 months after surgery. Finger movement, pain, hand function, postoperative finger infection, and tendon rupture will also be assessed at the scheduled follow-up visits.

Surgical Release of Hand Tendons With Wrapping of the Released Tendon Using an Amniotic Membrane

The goal of this clinical trial is to evaluate whether an amniotic membrane can function as an effective anti-adhesive barrier following surgical release of tendon adhesions. The main question the clinical trial aims to answer is: \- Can wrapping an amniotic membrane around a surgically released tendon help reduce recurrence of adhesions and promote recovery of hand functionality? Participants will: * Undergo surgical treatment (surgical release of the tendon adhesions and wrapping of the amniotic membrane around the release tendon) on Day 0. * Visit the center for a series of tests 15 days, 6 weeks, 3 months, 6 months after the surgical intervention.

Ultrasound-Guided Multiple Saline Injections for Prevention of Tendon Adhesion: A Randomized Controlled Trial

This prospective randomized controlled trial aims to evaluate the efficacy and safety of ultrasound-guided repeated normal saline injections for the prevention and treatment of tendon adhesion following flexor tendon repair. Tendon adhesion is a common complication after tendon injury, leading to pain, stiffness, and impaired hand function. Conventional anti-adhesion strategies, such as physical barrier membranes, may induce local inflammation or have limited effectiveness. In this study, patients undergoing tendon repair will be randomly assigned to receive either ultrasound-guided peritendinous saline injections at 7, 14, and 21 days after surgery (intervention group) or no injection (control group). The primary outcome is total active motion (TAM-%) at 3 months after surgery. Secondary outcomes include TAM-% at 6 weeks, pain scores (VAS), Michigan Hand Questionnaire (MHQ) scores, infection rate, and tendon rupture rate. A total of 136 patients will be enrolled (68 in each group). The findings of this trial will help to establish whether repeated saline injections under ultrasound guidance can effectively prevent tendon adhesion, improve pain and functional outcomes, and ensure tendon healing with minimal complications.
