Outcome of Flexor Tendon Repair Using Eight-Strand Core Stitch Without Postoperative Finger Splinting.

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Reconstructive Surgery

Background:

• Limited data exists on clinical outcomes of 8-strand suture techniques with early active mobilization.
• This study investigates the efficacy of an 8-strand double-cruciate core suture followed by early active motion without splinting.

Purpose of the Study:

• To evaluate the clinical outcomes of an 8-strand suture repair technique for flexor tendon injuries.
• To assess the effectiveness of early active mobilization without finger splinting post-surgery.

Main Methods:

• Thirty-five patients (41 digits) underwent an 8-strand double cruciate repair.
• Early active finger flexion/extension exercises commenced on postoperative day 3 with the wrist neutral.
• Follow-up was conducted for a minimum of 6 months.

Main Results:

• Proximal and distal interphalangeal joints achieved an average Total Active Motion (TAM) of 151° (86% of expected).
• Excellent/good outcomes were reported in 86.2% of fingers and 83.4% of thumbs based on established criteria.
• Extension lag was observed in 38% of fingers and 58% of thumbs; complications were infrequent.

Conclusions:

• The 8-strand repair with patient-performed active mobilization is practical, cost-effective, and prevents adhesions.
• Intensive hand therapist supervision may not be necessary, potentially reducing healthcare costs.
• Further research on flexor pollicis longus specifically is recommended to confirm these findings.
