Summary
Sustentaculum tali fractures, though rare, require anatomical fixation. Open reduction and internal fixation (ORIF) via a medial approach reliably restores foot arch integrity and function.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Foot and Ankle Surgery
Background:
- Sustentaculum tali fractures are uncommon, representing 1% of calcaneal fractures.
- These injuries are crucial due to the sustentaculum tali's role in maintaining the medial foot arch.
- Failure to achieve anatomical fixation can lead to post-traumatic arthrosis.
Purpose of the Study:
- To emphasize the significance of fixation for sustentaculum tali fractures.
- To detail the operative techniques employed.
- To report on the post-operative outcomes.
Main Methods:
- Open reduction and internal fixation (ORIF) was performed on 10 patients with closed sustentaculum tali fractures.
- The study included 9 males with an average age of 27.6 years.
- Follow-up averaged 52.8 months, with 7 isolated fractures and 3 associated fractures.
Main Results:
- All 10 fractures achieved radiological union within an average of 6.8 weeks (range 6-8 weeks).
- The overall average post-operative score was 97 (range 80-100), with isolated fractures scoring 100.
- No complications related to the surgical procedure were reported.
Conclusions:
- Sustentaculum tali fractures are rare, high-energy injuries often misdiagnosed.
- A high index of suspicion is necessary for prompt diagnosis.
- Medial approach ORIF is a reliable and effective treatment for these fractures.

Ampère's law, in its usual form, does not work in places where the current changes with time and is not steady. Thus, Maxwell suggested including an additional contribution, called the displacement current, Id, to the real conduction current I.

01:31Position and Displacement
26.6K
The position of an object defines its location relative to a convenient frame of reference at any particular time. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference, and we often describe the position of an object as it relates to stationary objects on Earth. For example, a rocket launch could be described in terms of the position of the rocket with respect to Earth as a whole. On the other...

To describe the motion of an object, one should first be able to describe its position (where it is at any particular time). More precisely, the position needs to be specified relative to a convenient frame of reference. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference to describe the position of an object in relation to stationary objects on Earth.

01:27Significance of Displacement Current
5.9K
A displacement current is analogous to a real current in Ampère's law, participating in Ampère's law the same way as the usual conduction current. However, it is produced by a changing electric field. Displacement current is defined in terms of a time-varying electric field, and also has an associated displacement current density. By adding a term accounting for displacement current, Maxwell modified the existing Ampère's law, which is now called generalized Ampère's law.

22.9K
Uniform circular motion is motion in a circle at a constant speed. Although this is the simplest case of rotational motion, it is very useful for many situations and is used to introduce rotational variables. When a particle is moving in a circle, the coordinate system is fixed and serves as a frame of reference to define the particle’s position. Its position vector from the origin of the circle to the particle sweeps out the angle θ, which increases in the counterclockwise direction...

01:30EDTA: Direct, Back-, and Displacement Titration
5.6K
The EDTA titration types for metal ion analysis include direct titration, back-titration, and replacement titration.
Direct titration involves buffering the metal ion solution to the desired pH and directly titrating with standard EDTA until the endpoint. The optimum pH ensures a large conditional formation constant of metal−EDTA and visibility of the free indicator color in the solution. In addition, auxiliary complexing reagents are used to prevent the precipitation of metal hydroxides...
