Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.7K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Obesity01:24

Obesity

1.4K
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

7.1K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Structural Joints: Fibrous Joints01:03

Structural Joints: Fibrous Joints

3.8K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

4.1K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Joints01:26

Joints

35.8K
Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable
The bones of a...

Area of Science:

  • Orthopedic Surgery
  • Public Health
  • Bariatric Medicine

Background:

  • Obesity is a widespread epidemic impacting healthcare systems globally.
  • Obesity introduces unique complications and challenges for arthroplasty surgeons.
  • Increased risks of infection, dislocation, and poorer outcomes are associated with obese patients undergoing joint replacement.

Purpose of the Study:

  • To highlight the challenges posed by obesity in arthroplasty.
  • To emphasize the importance of preoperative weight loss in obese patients.
  • To stress the need for realistic patient counseling regarding outcomes.

Main Methods:

  • Review of existing literature on obesity and arthroplasty outcomes.
  • Analysis of risks associated with obesity in total joint arthroplasty.
  • Discussion of modifiable risk factors and patient counseling strategies.

Main Results:

  • Obese patients face higher risks for surgical site infections and joint dislocations.
  • Poorer implant survivorship and lower functional scores are observed postoperatively in obese individuals.
  • Obesity is identified as a significant, yet modifiable, risk factor influencing arthroplasty success.

Conclusions:

  • Preoperative weight loss should be strongly considered for obese patients undergoing arthroplasty.
  • Comprehensive counseling is essential to set realistic expectations for obese patients post-surgery.
  • Addressing obesity is key to improving outcomes and managing challenges in arthroplasty care.
