Summary
Complications from external skeletal fixator (ESF) use in dogs are frequent, often involving implant infections. Careful consideration of ESF placement, especially transarticular frames, is crucial to mitigate risks.
Area of Science:
- Veterinary Orthopedics
- Surgical Complications
- Canine Fracture Management
Background:
- External skeletal fixators (ESF) are widely used for canine fracture repair.
- Understanding ESF-related complication risks is essential for optimal patient outcomes.
Purpose of the Study:
- To quantify and evaluate the risks of complications associated with external skeletal fixator (ESF) usage in dogs.
- Identify factors influencing complication incidence and type.
Main Methods:
- Retrospective review of medical records for 97 dogs undergoing ESF placement.
- Analysis of complication rates based on ESF location, frame type, and patient factors.
Main Results:
- A high incidence of ESF-associated complications was observed in 79% of dogs.
- Complication rates varied significantly by ESF region (tarsus, manus, humerus most affected) and transarticular frame use.
- Superficial pin-tract infection (38%) and implant failure (17%) were the most common complications; age was also a significant factor.
Conclusions:
- Fixator-associated complications are common in dogs, primarily due to implant infections.
- ESF region and the use of transarticular frames require careful consideration during stabilization method selection to minimize risks.

01:11Work Done on a System by External Force
3.0K
The work done by an external force on a particle changes its kinetic energy. However, internal forces must also be considered for a system of interacting particles. The potential energy formulation helps formulate the effect of internal forces. The net work done by an external force can be written in terms of the total change of mechanical energy, which includes both kinetic and potential energies.

970
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

01:48Classification of Skeletal Muscle Fibers
59.6K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

01:12Internal and External Forces
16.4K
Newton's first law states that a net external force causes a change in motion. External forces act on an object or system, originating outside of the object or system. In contrast, internal forces originate inside the system of interest and do not lead to any acceleration. In simpler words, internal forces are forces that act on one part of an object and are exerted by another part of the same object. External forces are forces that act on an object due to some other object. Therefore, when...

01:24External and Internal Respiration
7.8K
External respiration occurs in the lungs, and it is the first step in the journey of oxygen inside the body. When we inhale, oxygen enters our lungs and diffuses across the thin alveolar membrane. The alveoli are tiny, air-filled sacs that provide a vast surface area for gas exchange. Oxygen in the alveoli has a higher partial pressure (105 mmHg) than in the adjacent pulmonary capillaries (40 mmHg), establishing a pressure gradient. As a result, oxygen molecules move from the alveoli into the...
