• Board Certiﬁed in Foot Surgery and Reconstructive Rearfoot and Ankle Surgery

• Consultant for Medline Foot & Ankle Surgery Flat Foot Deformity

• Frontal Plane

• Transverse Plane

• Sagittal Plane PTTD

• Posterior Tibial Tendon

• Is it “dysfunctional” Pathology

• Spring Ligament

• Attenuation leads to increased force on the posterior tibial tendon.

• Spring Ligament and PT Tendon play essential role in elastic support of joint complex

• Progressive strain on the mid- plantar sling is the most common cause of ﬂatfoot, causing midfoot abduction

• Regardless of the etiology, literature is demonstrating the spring ligament is failing and becoming attenuated, needs ﬁxed

• The most important static structure to be repaired for AAFD is the spring ligament.
