A case study of endoscopic tendon suturing for finger flexor tendon injuries.

Basic Information

Recruitment status	Pending
Health condition(s) or Problem(s) studied	flexor tendon injury
Date of first enrollment	01/11/2025
Target sample size	2
Countries of recruitment
Study type	Interventional
Intervention(s)	Endoscopic Assisted and Direct Visualization Flexor Tendon Suture Technique Procedure. An endoscope is inserted into the tendon sheath through the injury site to visualize the tendon ends, which are then sutured using a 2-strand technique (Reference 3). The suture threads are pulled to expose the tendon ends outside the wound, followed by a total of 6~8 strand sutures under direct visualization. End to end suturing or fixation using suture anchors or suture buttons is performed. Treatment Duration: Observation for 2 years post-surgery. Location: Fukushima Medical University Hospital or Hama-Kosei Hospital.

Outcome(s)

Primary Outcome	Joint range of motion at 1~7 days, 2~4 weeks, 2, 3, and 6 months, and 1 and 2 years post-surgery.
Secondary Outcome	Evaluated at 1~7 days, 2~4 weeks, 2, 3, and 6 months, and 1 and 2 years post surgery: Postoperative Performance Evaluation: Pain, edema, and DASH (Disabilities of the Arm, Shoulder, and Hand) score. Complication Evaluation: Tendon adhesion, scarring, and neurovascular injury. Other: Suture time and total operative time.
