The plantar surface of the foot contains an intricate network of ligaments and tendons that provide essential support and dynamic function. This superior view demonstrates the complex relationships between various plantar structures, highlighting their crucial roles in maintaining foot stability and facilitating proper biomechanics during gait and weight-bearing activities.

Plantar Intermetatarsal Ligaments Connect adjacent metatarsal bones on their plantar surface. These strong ligaments maintain proper metatarsal spacing and provide stability during push-off phase.
Plantar Tarsometatarsal Ligaments Join the tarsal bones to metatarsal bases. These ligaments help maintain the transverse arch and provide stability during midstance phase of gait.
Tendon Peroneus Longus Muscle A key lateral compartment muscle whose tendon courses under the foot. It serves to evert the foot and plantarflex the first ray, contributing to arch support.
Tendon Tibialis Anticus Muscle The primary dorsiflexor of the ankle and invertor of the foot. This tendon helps maintain the medial longitudinal arch and controls foot position during swing phase.
Plantar Cuneonavicular Ligament Connects the cuneiforms to the navicular bone on the plantar surface. It provides essential support to the medial column of the foot.
Plantar Calcaneocuboid Ligament Links the calcaneus to the cuboid bone plantarly. This ligament is crucial for lateral column stability and helps maintain the lateral longitudinal arch.
Plantar Cuboideonavicular Ligament Joins the cuboid and navicular bones on their plantar aspect. It helps maintain midfoot stability and transverse arch integrity.
Long Plantar Ligament The longest plantar ligament, extending from calcaneus to metatarsal bases. It provides critical support to the lateral longitudinal arch.
Tendon Tibialis Posticus Muscle A key dynamic supporter of the medial longitudinal arch. This tendon inverts the hindfoot and supports the medial column during stance phase.
Comprehensive Analysis of Plantar Foot Structures
Anatomical Organization
The plantar foot ligaments create an intricate support system. These structures maintain arch integrity and provide dynamic stability during gait phases.
Layered Architecture
The plantar surface consists of:
- Superficial layer (plantar fascia and short plantar ligament)
- Intermediate layer (long plantar ligament)
- Deep layer (interosseous ligaments)
Biomechanical Function
Dynamic Support
During gait cycles, these structures:
- Control arch deformation
- Assist in energy storage/release
- Maintain joint congruity
- Provide proprioceptive feedback
Load Distribution
Key functions include:
- Force transmission during push-off
- Shock absorption at heel strike
- Lateral column stabilization
- Medial arch maintenance
Clinical Significance
Common Pathologies
Frequent conditions include:
- Plantar fasciitis
- Spring ligament dysfunction
- Tendon disorders (tibialis posterior, peroneus longus)
- Midfoot arthritis
Diagnostic Approach
Physical Examination
Essential tests:
- Jack’s test
- Hubscher maneuver
- Tarsometatarsal stability
- Coleman block test
Imaging Studies
Include:
- Weight-bearing radiographs
- Dynamic ultrasound
- MRI for soft tissue pathology
- Stress views
Treatment Strategies
Conservative Management
Initial approaches:
- Activity modification
- Orthotic devices
- Physical therapy
- Taping techniques
Surgical Intervention
Options include:
- Ligament repair/reconstruction
- Tendon transfers
- Joint arthrodesis
- Osteotomies
Rehabilitation Protocols
Acute Phase
Focus on:
- Protection
- Edema control
