Summary
Fixed angle locking plates offer a viable solution for complex comminuted patella fractures, demonstrating good functional recovery and low complication rates. This technique ensures stable fixation, promoting successful fracture healing and improved patient outcomes.
Area of Science:
- Orthopedic Surgery
- Trauma Surgery
- Biomedical Engineering
Background:
- Comminuted patella fractures present significant management challenges due to their complexity.
- Limited clinical data exists for various treatment modalities of these fractures.
- Recent advancements suggest plate fixation as a promising approach.
Purpose of the Study:
- To evaluate the radiographic, clinical, and functional outcomes of comminuted patella fractures treated with fixed angle locking plates.
- To assess the efficacy and safety of this fixation technique in achieving fracture union and functional recovery.
Main Methods:
- Retrospective review of 36 patients with AO/OTA 34C2 and C3 patella fractures treated with fixed angle locking plates.
- Follow-up averaged 154 weeks, with 20 patients assessed for functional outcomes using KOS and LES scores and goniometry.
- Secondary outcomes included need for supplemental fixation, reoperation, hardware irritation, infection, and nonunion.
Main Results:
- Patients achieved an average Knee Outcome Score (KOS) of 57.2 and Lower Extremity Functional Scale (LES) of 58.9.
- Median knee range of motion was 0° extension and 130° flexion.
- Low complication rates were observed, with only minor hardware irritation in 4/20 patients and no nonunions.
Conclusions:
- Fixed angle plate stabilization is an effective and viable technique for comminuted patella fractures.
- The method facilitates good to excellent knee function restoration with a low incidence of complications.
- This approach supports stable fixation, successful union, and satisfactory functional recovery.

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

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...

01:27Open Angle Glaucoma: Treatment
1.0K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

14.9K
The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

01:13Angle of Twist: Problem Solving
813
An electric motor applies a torque of 700 N·m to an aluminum shaft, triggering a stable rotation. Two pulleys, B and C, are subjected to torques of 300 N·m and 400 N·m, respectively. The modulus of rigidity is provided as 25 GPa. With the knowledge of the length and diameter of each segment, the twist angle between the two pulleys can be computed. First, a section cut is made between pulleys B and C, and the cut cross-section is analyzed using a free-body diagram. Given that the torque...
