• BACKGROUND
    • Adult-acquired flatfoot deformity (AAFD) is usually due to a combination of mechanical failure of the osteoligamentous complex that maintains the medial longitudinal arch of the foot and attenuation or complete tear of the posterior tibial tendon. Magnetic resonance imaging studies in patients with flatfoot deformities have reported the posterior tibial tendon to be pathologic in up to 100% of patients, the spring ligament in up to 87%, and the deltoid ligament in 33%. Many studies in the literature describe reconstruction of the spring ligament or the deltoid ligament associated with AAFD, but there is no study in which both (spring and deltoid) ligaments are reconstructed at the same time. We describe a novel technique to reconstruct the deltoid ligament and the spring ligament at the same time.
  • METHODS
    • We described the technique and evaluated 10 consecutive patients with AAFD and insufficient ankle and midfoot ligaments.
  • RESULTS
    • We found no postoperative complications, stiffness, or loss of correction.
  • CONCLUSION
    • We present a novel technique to reconstruct the failed deltoid and spring ligament during flatfoot correction. It is unique in that it uses internal brace augmentation with FiberTapeĀ® to help and protect the soft tissue healing.
  • LEVEL OF EVIDENCE
    • Level IV, retrospective case series.
