Summary
This study details an endoscopic approach for flexor digitorum longus (FDL) tendon transfer, a key treatment for adult flexible flatfoot caused by posterior tibial tendon insufficiency. The technique is safe and reproducible, offering a promising surgical option.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Reconstruction
Background:
- Posterior tibial tendon insufficiency is the primary cause of adult flexible flatfoot.
- Flexor digitorum longus (FDL) transfer is a recognized treatment, often combined with osteotomy.
- Existing techniques may involve open or percutaneous calcaneal osteotomy.
Purpose of the Study:
- To describe a novel endoscopic technique for FDL transfer.
- To evaluate the feasibility and reproducibility of the endoscopic FDL transfer procedure.
Main Methods:
- Detailed description of the endoscopic FDL transfer technique.
- Focus on the specific steps and surgical approach.
Main Results:
- The endoscopic FDL transfer procedure was performed safely.
- The technique demonstrated reproducibility under direct visualization.
- The procedure is suitable for patients with flexible flatfoot.
Conclusions:
- Endoscopic FDL transfer is a safe and reproducible technique for flexible flatfoot.
- Further clinical studies are warranted to validate outcomes in a larger patient cohort.
