| Component | Full Name | Function | Tear Pattern | Clinical Finding |
|---|---|---|---|---|
| Superomedial (SM) Band | Superomedial calcaneonavicular ligament | Primary static support of talar head; prevents talar plantarflexion and medial rotation; most critical to arch | Most commonly torn (isolated or with PTT) | Talonavicular uncoverage on WB X-ray; medial arch collapse; PTT attenuation |
| Inferoplantar (IP) Band | Inferoplantar longitudinal calcaneonavicular ligament | Supports inferior talar head; reinforces plantar arch | Torn with SM band in severe flatfoot | More severe flatfoot deformity when both bands torn |
| Medioplantar (MP) Oblique Band | Medioplantar oblique calcaneonavicular ligament | Connects calcaneus to navicular medially | Less commonly isolated | Often part of complex spring ligament failure |
| Treatment | PTTD Stage | Technique | Spring Ligament Role | Outcome |
|---|---|---|---|---|
| Conservative (AFO + PT) | Stage I; symptomatic but flexible | UCBL or rigid AFO; PT for PTT and intrinsic strengthening; posterior tibial tendon rehab | Ligament not addressed surgically; offloading supports it | Good for Stage I; does not reverse ligament attenuation |
| Spring Ligament Primary Repair | Stage II with isolated spring ligament tear; acute | Direct suture anchor repair of superomedial band to calcaneus and navicular; augmented with local periosteum | Primary repair restores static medial column support | 75–85% good outcomes when combined with bony correction |
| Spring Ligament Reconstruction (Allograft) | Stage II–III with attenuated / non-repairable spring ligament | Gracilis, tibialis anterior, or FDL allograft routed through navicular and calcaneal tunnels | Replaces failed ligament with graft tissue; stronger than repair alone | 80–85% with allograft reconstruction + calcaneal osteotomy |
| MDCO + Spring Ligament Repair (Combined) | Stage II PTTD; heel valgus + spring ligament failure | Medial displacement calcaneal osteotomy restores hindfoot alignment; spring ligament repair restores navicular support | Osteotomy reduces tension on spring ligament repair; required for durability | 85–90% good/excellent combined; better than either alone |
| Triple Arthrodesis | Stage III rigid flatfoot with spring ligament failure | Subtalar + talonavicular + calcaneocuboid fusion; spring ligament not repaired (joint fused) | Fusion eliminates need for spring ligament function | Good pain relief and stability in rigid deformity |

Quick Answer:
Quick Answer: The spring ligament (plantar calcaneonavicular ligament) is the primary static supporter of the medial longitudinal arch — the ‘hammock’ that suspends the talar head and prevents arch collapse. Spring ligament tears are a significant cause of adult-acquired flatfoot deformity and frequently accompany posterior tibial tendon dysfunction (PTTD). Complete or severe partial spring ligament tears allow the talar head to plantar-flex and medially deviate into the ‘sag’ position that produces the flatfoot posture. MRI demonstrates ligament continuity loss, talar head uncovering, and often coexisting PTTD changes. Treatment for symptomatic spring ligament insufficiency is surgical when conservative management (UCBL orthosis, immobilization) fails — spring ligament repair with or without augmentation (peroneus longus allograft, synthetic ligament augmentation) is combined with bony correction procedures (medializing calcaneal osteotomy, lateral column lengthening) for durable flatfoot reconstruction.
The spring ligament — technically the plantar calcaneonavicular ligament complex — is the primary passive support structure of the medial longitudinal arch. It spans from the sustentaculum tali of the calcaneus to the navicular, creating the sling that supports the talar head and prevents the arch from collapsing under body weight. Spring ligament insufficiency is an underappreciated but critical component of adult-acquired flatfoot deformity — and without addressing it surgically, flatfoot reconstruction procedures fail at higher rates. Dr. Biernacki at Balance Foot & Ankle includes spring ligament assessment in every evaluation of adult flatfoot deformity.
Anatomy and Biomechanical Role
The spring ligament complex consists of three components: the superomedial calcaneonavicular ligament (SMCNL) — the most clinically important component, acting as the true ‘spring’ supporting the talar head; the inferoplantar longitudinal ligament; and the medioplantar oblique ligament. The SMCNL has a fibrocartilaginous articular surface on its superior aspect that provides direct contact support for the talar head articular cartilage. When the SMCNL fails — from cumulative degeneration, PTTD overload (the dynamic arch support fails before the static arch gives way), or acute injury — the talar head plantarflexes and medializes into the sag, driving forefoot abduction and hindfoot valgus. This is the biomechanical cascade that produces the classic adult acquired flatfoot posture.
Diagnosis: MRI with Attention to the Spring Ligament
Spring ligament pathology is frequently overlooked on standard MRI reads unless specifically assessed. Dr. Biernacki requests dedicated spring ligament evaluation when ordering ankle/foot MRI for adult flatfoot cases. Characteristic MRI findings: SMCNL signal change (heterogeneous T2 signal indicating degeneration), ligament discontinuity (complete tear), and talar head uncovering on standing lateral X-ray (the talar head drops below the navicular, producing the ‘sagging’ arch appearance). Weightbearing radiographic measurements — talo-first metatarsal angle (Meary’s angle), calcaneal pitch, and talar coverage angle — objectively quantify deformity severity and guide surgical planning.
Surgical Spring Ligament Repair and Reconstruction
Isolated spring ligament repair is rarely performed — most cases require concurrent bony realignment (calcaneal osteotomy, lateral column lengthening) to address the structural deformity driving ligament stress. The surgical sequence for adult flatfoot reconstruction with spring ligament involvement: (1) Medializing calcaneal osteotomy — realigns hindfoot valgus, reduces medial column loading; (2) Lateral column lengthening (Evans osteotomy) for significant forefoot abduction; (3) Spring ligament repair — primary repair of the SMCNL tear with suture anchor fixation; (4) Augmentation with peroneus longus allograft or synthetic ligament (InternalBrace concept) when primary tissue quality is poor; (5) FDL tendon transfer to replace incompetent posterior tibial tendon. The reconstruction addresses all four deficits (dynamic tendon, primary static ligament, and bony alignment) for durable, recurrence-resistant correction.
Recovery After Flatfoot Reconstruction
Flatfoot reconstruction with spring ligament repair involves: 6–8 weeks non-weight-bearing in a cast or boot following surgery; progressive weight-bearing in a boot at 6–8 weeks with physical therapy for range of motion and peroneal/posterior tibial strengthening; transition to supportive footwear and custom orthotics at 3–4 months; return to full unrestricted activity at 6–12 months. Patient expectations are important to set — the reconstructed foot is not a normal foot, but a functional, pain-free foot that avoids the progressive deformity and arthritis of untreated PTTD with spring ligament insufficiency.

Dr. Tom Biernacki’s Recommendation
The spring ligament is the arch’s hidden foundation — and when it fails, the arch doesn’t just look flat, it actually collapses dynamically with every step, driving progressive tendon and joint destruction. I always look at the spring ligament on MRI for adult flatfoot cases, because ignoring it in surgical planning leads to higher failure rates and recurrence. A properly planned reconstruction that addresses the bony alignment, the posterior tibial tendon, AND the spring ligament gives patients the best chance at a durable, long-term good outcome.

Frequently Asked Questions
What is the spring ligament and why does it matter?
The spring ligament (plantar calcaneonavicular ligament) is the primary passive structure supporting the talar head and maintaining the medial arch. Without intact spring ligament support, the talar head sags — causing the arch collapse characteristic of adult flatfoot. It’s the ‘hammock’ that holds up the arch, and when it tears, the arch loses its foundation.
How is a spring ligament tear diagnosed?
MRI with specific attention to the superomedial calcaneonavicular ligament (SMCNL) identifies tears — signal heterogeneity and discontinuity. Standing lateral X-rays showing Meary’s angle (talo-first metatarsal angle) quantify the deformity produced by the ligament failure. Weight-bearing evaluation is essential — non-weight-bearing MRI may underestimate deformity.
Can the spring ligament heal without surgery?
Partial tears with mild deformity may stabilize with custom UCBL orthosis and PTTD treatment. Complete SMCNL tears with significant talar head sag typically do not heal functionally without surgical repair — the deformity and loading forces prevent tissue approximation. Conservative management manages symptoms but doesn’t correct the underlying structural problem.
Is spring ligament repair done at the same time as bunion surgery?
Spring ligament repair is not typically combined with bunion surgery alone. It is most commonly combined with flatfoot reconstruction procedures (calcaneal osteotomy, FDL tendon transfer) that address the global flatfoot deformity. Combining procedures is the standard of care for comprehensive deformity correction.
