Due to pes planovalgus or posterior tibial insuﬃciency). Heel Compression Test The examiner symmetrically compresses the heel between the balls of both thumbs. With a fracture of the calcaneus, this test will elicit pain in the heel. Single-Heel-Rise Test The inability to rise onto the toes while standing on one leg signifies a lesion of the posterior tibial tendon. Silfverskiöld Test (▶ Fig. 5) This maneuver tests the correctibility of equinus deformity with the knee joint flexed and extended.
Sequences: ○ Coronal T1-weighted, parallel to the transverse axis of the ankle joint through the talus and malleoli ○ Sagittal and coronal PD (proton density)-weighted fat-sat (fat saturation) ○ Axial T2-weighted, angled parallel to the anterior talofibular ligament ○ If necessary: axial oblique PD-weighted fat-sat sequence in the syndesmotic plane Midsubstance tear, fibular, or talar avulsion of the anterior talofibular ligament with a visible discontinuity and wavy contours of the ligament stump Associated anterolateral capsule tear with edema and hemorrhage along the anterolateral soft tissues Interstitial hemorrhage and increased signal intensity with/ without continuity disruption in the calcaneofibular ligament (the posterior talofibular ligament is generally intact) Frequent significant hemorrhage and marked soft-tissue hematoma encircling the ankle joint, most pronounced anterolaterally due to the disruption of subcutaneous and deeper veins Contusional bone edema on the medial talar border, medial malleolus, talar shoulders, etc.
The spring ligament fibers have an expanded, wavy appearance with minimal adjacent posterior tibial peritendinitis. Note MRI Findings (▶ Fig. 10) ● It is important to identify the spring ligament and survey it in detail for pre-existing degenerative changes and injuries. ● Interpretation Checklist ● ● ● ● Ligament continuity Complete or partial tear Bony avulsion Associated injuries ● ● ● The MRI report should address all relevant, vulnerable structures of the hindfoot and midfoot. Because traumatic spring ligament tears often occur in a setting of posterior tibial insuﬃciency with pre-existing medial instability, it is important to address the entire medial axis with its dynamic stabilizers (posterior tibial tendon) and static stabilizers (spring ligament, superficial portions of the deltoid ligament, plantar fascia, long plantar ligament) when describing the spring ligament injury.
