The posterior view of the foot and ankle complex reveals an intricate arrangement of ligaments, tendons, and bony structures that provide stability and enable complex movements. This detailed anatomical understanding is crucial for healthcare professionals in diagnosing and treating various foot and ankle pathologies.

Tibia The main weight-bearing bone of the lower leg that forms the medial portion of the ankle mortise. Its distal end creates the medial malleolus, which is crucial for ankle stability.
Fibula The lateral long bone of the leg that provides attachment points for numerous ligaments and muscles. Its distal end forms the lateral malleolus, essential for lateral ankle stability.
Maleola mediala (Medial malleolus) The medial projection of the distal tibia that forms a crucial part of the ankle mortise. It serves as an attachment point for the deltoid ligament complex.
Lig. tibiofibular posterior A strong ligament connecting the posterior aspects of the tibia and fibula. It maintains the integrity of the distal tibiofibular syndesmosis.
Lig. talofibular posterior A strong, horizontal ligament extending from the lateral malleolus to the posterior talus. It provides crucial posterior stability to the ankle joint.
Maleola laterală (Lateral malleolus) The distal end of the fibula forming the lateral aspect of the ankle. It provides attachment for the lateral ligament complex.
Lig. talocalcanean posterior A short, broad ligament connecting the posterior aspects of the talus and calcaneus. It helps stabilize the subtalar joint.
Lig. calcaneofibular A strong cord-like ligament extending from the lateral malleolus to the calcaneus. It provides lateral stability during weight-bearing activities.
Talus The ankle bone that articulates with the tibia and fibula above and the calcaneus below. It is crucial for transferring body weight and enabling ankle motion.
Calcaneu (Calcaneus) The largest tarsal bone forming the heel of the foot. It provides attachment for the Achilles tendon and multiple ligaments.
Tendonul calcanean (Achilles tendon) The strongest tendon in the body, connecting the calf muscles to the calcaneus. It is essential for plantar flexion and push-off during gait.
Tuberozitatea calcaneană (Calcaneal tuberosity) The posterior projection of the calcaneus serving as the attachment point for the Achilles tendon. It provides leverage for the calf muscles.
Posterior Ankle Complex: Structure and Biomechanics
The posterior ankle complex represents a sophisticated biomechanical system essential for human locomotion. The integration of multiple ligaments and tendons creates a dynamic support structure that maintains stability while allowing necessary mobility.
Ligamentous Support System
The posterior aspect of the ankle contains several key ligamentous structures that work synergistically. These ligaments provide both static and dynamic stability during various movements and weight-bearing activities.
The posterior ligament complex includes:
- Deep component: posterior talofibular and tibiofibular ligaments
- Superficial component: posterior talocalcaneal and calcaneofibular ligaments
Neural and Vascular Components
The posterior ankle region houses critical neurovascular structures that supply the foot. The tibial nerve and posterior tibial vessels pass behind the medial malleolus, protected by the flexor retinaculum.
Clinical Significance and Pathologies
Common Posterior Ankle Conditions
Posterior ankle pathologies frequently involve the Achilles tendon complex. Tendinopathy, ruptures, and insertional problems represent significant clinical challenges requiring specific diagnostic and treatment approaches.
Diagnostic Approaches
Modern imaging techniques including MRI and ultrasound provide detailed visualization of posterior ankle structures. Dynamic assessment protocols help evaluate ligament integrity and tendon function.
Surgical Considerations
Operative Techniques
Surgical approaches to the posterior ankle require careful consideration of neurovascular structures. Minimally invasive techniques have revolutionized the treatment of various posterior ankle pathologies.
Post-operative Management
Evidence-based rehabilitation protocols following posterior ankle surgery emphasize:
- Protected weight-bearing progression
- Controlled range of motion exercises
- Gradual strengthening
- Proprioception training
Rehabilitation Strategies
Conservative Management
Non-operative treatment of posterior ankle conditions focuses on:
- Modified activity levels
- Therapeutic exercise
- Manual therapy techniques
- Appropriate footwear modifications
Return to Function Protocols
Progressive rehabilitation programs incorporate:
- Phase-specific exercise progression
- Functional movement training
- Sport-specific conditioning
- Performance testing criteria
