Summary
Immediate flexor digitorum longus (FDL) tendon-to-bone repair using a miniaturized anchor shows good functional results, including improved motion and pinch strength. This technique offers advantages over transcutaneous devices, reducing infection risk and enhancing patient comfort.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Musculoskeletal Research
Background:
- Flexor digitorum longus (FDL) tendon injuries require effective surgical repair.
- Immediate tendon-to-bone repair aims to restore function and minimize complications.
Purpose of the Study:
- To evaluate subjective and functional outcomes of immediate FDL tendon-to-bone repair using a miniaturized anchor.
- To assess the efficacy and safety of this minimally invasive surgical technique.
Main Methods:
- Prospective study of seven patients undergoing emergency FDL tendon repair in zone one.
- Distal tendon re-attachment performed with a mini-G II Mitek anchor suture.
- Early active mobilization with Duran-type splinting and 10-month follow-up.
Main Results:
- High patient satisfaction reported (6/7 satisfied, 1/7 very satisfied).
- Total Active Motion (TAM) averaged 92% of the contralateral finger; pinch force reached 81%.
- Minimal complications, with no functional impact from the single implant-related issue.
Conclusions:
- Anchor-based FDL tendon-to-bone repair yields favorable subjective and functional results.
- This method demonstrates advantages over transcutaneous devices, including reduced infection risk and improved patient comfort.
- The technique shows comparable outcomes to other repair methods while offering enhanced patient benefits.
