Summary
Rare open ankle dislocations without fracture can involve tendon interposition. This case highlights tibialis posterior tendon interposition, a diagnosis often missed without advanced imaging and careful surgical evaluation.
Area of Science:
- Orthopedic Surgery
- Radiology
- Trauma Care
Background:
- Open ankle dislocations are uncommon injuries.
- Tendon interposition is a rare complication, typically associated with ankle fracture-dislocations.
- Prompt diagnosis and management are crucial for optimal patient outcomes.
Observation:
- A unique case of open ankle dislocation without fracture is presented.
- Tibialis posterior tendon interposition through the interosseous space was incidentally discovered.
- Computed tomography (CT) played a key role in identifying the interposition.
Findings:
- The study details the clinical presentation, radiological findings, and intraoperative management of this rare condition.
- Computed tomography (CT) revealed the incidental finding of tibialis posterior tendon interposition.
- This case underscores the importance of thorough diagnostic evaluation in seemingly straightforward injuries.
Implications:
- Highlights the potential for missed diagnoses in open ankle dislocations without fracture.
- Emphasizes the utility of advanced imaging like CT in identifying subtle tendon injuries.
- Provides valuable insights for clinicians to avoid diagnostic errors and improve surgical planning for similar rare cases.

01:10Ankle Joint
3.3K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

01:10Bones of the Lower Limb: Tibia and Fibula
13.8K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

01:28Muscles of the Leg that Move the Foot and Toes
4.4K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
