Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

6.8K
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

3.7K
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

4.0K
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...

Joints

35.6K
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

Introduction to Joints

4.8K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...

Ankle Joint01:10

Ankle Joint

2.9K
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...

Summary

Artificial joint replacement offers mobility for deformed finger joints, with silicone implants remaining a reliable option. Newer modular implants show promise, with decreasing complication rates for osteoarthritis treatment.

Area of Science:

  • Orthopedic surgery
  • Hand surgery
  • Biomaterials

Background:

  • Osteoarthritis and inflammatory conditions can deform finger middle joints, necessitating treatment options beyond arthrodesis.
  • Artificial joint replacement provides mobility, leading to higher patient acceptance compared to fusion procedures.

Purpose of the Study:

  • To evaluate clinical and subjective outcomes of artificial finger middle joint replacement.
  • To assess the complication rates associated with various artificial joint types.
  • To review long-term experiences and recent advancements in finger joint arthroplasty.

Main Methods:

  • Retrospective review of experiences with diverse artificial joint implants over several decades.
  • Inclusion of data on new developments in finger joint replacement from the last 10 years.

Main Results:

  • Silicone implants are the current gold standard, demonstrating good long-term results and low revision rates.
  • Challenges with silicone implants include potential issues with lateral stability and pre-existing axis deviations.
  • Modular resurfacing implants show promising initial results and may offer a long-term alternative to silicone spacers, though long-term data is still pending.

Conclusions:

  • Motion-preserving artificial joints effectively treat painful finger joint osteoarthritis.
  • The complication rate associated with finger joint replacement is decreasing.
  • Newer modular surface prostheses appear comparable to silicone spacers in long-term outcomes.
