Summary
This study details a rare talar neck fracture with a 180° inverted talar dome, exceeding the standard Hawkins classification. It highlights the need for specific surgical approaches and guarded prognoses for such complex foot and ankle injuries.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Radiology
Background:
- Talar neck fractures are classified using the Hawkins-Canale system, predicting osteonecrosis risk.
- These fractures present a wide spectrum of injury patterns, posing treatment challenges.
Observation:
- A unique case of talar neck fracture with a 180° dislocated and inverted talar dome is presented.
- This specific injury pattern is not encompassed by the current Hawkins classification.
Findings:
- The case demonstrates the limitations of the Hawkins classification for extreme talar dome displacement.
- Urgent open reduction, transcalcaneal traction pin, and dual incisions are recommended for this injury.
Implications:
- This case expands the understanding of talar neck fracture presentations.
- It suggests a need for tailored treatment strategies and emphasizes a guarded prognosis for osteonecrosis and posttraumatic arthritis in severe talar neck fractures.

01:10Ankle Joint
1.7K
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...

01:27Fractures: Bone Repair
3.5K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

01:28Articulations of the Vertebral Column
2.1K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

01:10Bones of the Lower Limb: Tibia and Fibula
4.4K
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...
