Summary
Open medial navicular dislocation is rare. Prompt surgical reduction and stabilization can lead to good outcomes, but avascular necrosis and midfoot collapse are potential complications requiring further intervention.
Area of Science:
- Orthopedic surgery
- Traumatology
- Podiatric medicine
Background:
- Traumatic injuries to the tarsal navicular bone are uncommon, particularly dislocations of an intact bone.
- Open dislocations present unique challenges in management and prognosis.
Observation:
- A case of open medial navicular dislocation in a 45-year-old male patient is presented.
- Initial management involved open reduction and Kirschner wire stabilization.
Findings:
- The patient developed avascular necrosis of the navicular and medial midfoot collapse 10 months post-injury.
- A subsequent naviculocuneiform arthrodesis was performed 1 year after the initial surgery.
Implications:
- Successful treatment of complex midfoot injuries necessitates a thorough understanding of foot anatomy, biomechanics, and potential complications.
- Early and definitive management strategies are crucial for optimizing long-term functional recovery in patients with navicular dislocations.

01:10Ankle Joint
3.2K
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...

01:15Bones of the Upper Limb: Ulna
10.2K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

01:10Bones of the Lower Limb: Tibia and Fibula
13.7K
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...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

01:09Bones of the Upper Limb: Radius
10.5K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

01:19Bones of the Upper Limb: Humerus
13.1K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
