Summary
A novel bone block procedure with periosteal augmentation shows promising results for peroneal tendon dislocation, especially in cases with severe retinaculum deficiency. This technique offers a viable surgical option for improved patient outcomes and stability.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Tendon Repair
Background:
- Peroneal tendon dislocation is a rare but debilitating condition impacting active individuals.
- Standard treatments like superior peroneal retinaculum (SPR) repair may fail in severe SPR deficiency.
- A modified bone block procedure with periosteal augmentation was developed for enhanced stability.
Purpose of the Study:
- To evaluate the clinical and functional outcomes of a modified bone block procedure with periosteal augmentation for peroneal tendon dislocation.
- To assess the efficacy of this technique in patients with severe SPR deficiency where standard repair is insufficient.
Main Methods:
- Retrospective case series of 12 patients (11 analyzed) treated between 2005-2025.
- Surgical technique involved a modified DuVries osteotomy with a fibular bone block and inverted periosteal flap.
- Outcomes assessed using AOFAS, SF-12, VAS, MOXFQ, Tegner scores, and return-to-activity rates.
Main Results:
- Significant improvements observed in AOFAS, SF-12, VAS, MOXFQ, and Tegner scores post-surgery.
- All patients returned to daily activities; athletes resumed sports.
- Mean follow-up of 68.2 months with no recurrence; one case of transient sural nerve irritation.
Conclusions:
- The modified bone block procedure with periosteal augmentation yields favorable clinical and functional results.
- This technique is a potential surgical option for peroneal tendon dislocation, particularly with severe SPR insufficiency.
- The procedure offers enhanced mechanical stability compared to isolated soft-tissue repair.
