Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

6.5K
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

3.6K
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

3.9K
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

35.5K
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 Joints00:58

Introduction to Joints

4.7K
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

2.8K
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
This summary is machine-generated.

Proximal interphalangeal joint (PIPJ) dislocations most often affect young men during sports and older individuals after falls. Open dislocations typically involve the index and middle fingers, with variable follow-up rates indicating potential for prolonged symptoms.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Biomechanics

Background:

  • Finger proximal interphalangeal joint (PIPJ) dislocations are common injuries.
  • Understanding the demographics and biomechanics of PIPJ dislocations is crucial for effective management.

Purpose of the Study:

  • To analyze the demographics and biomechanics of proximal interphalangeal joint (PIPJ) dislocations.
  • To identify distinct patient populations and injury patterns associated with PIPJ dislocations.

Main Methods:

  • Retrospective review of PIPJ dislocations over a 2-year period.
  • Data collected included demographics, injury mechanism, dislocation direction, concomitant injuries, and follow-up rates.
  • Radiological assessment was used to determine the direction of dislocation.

Main Results:

  • 74 adult patients (median age 46 years) experienced 74 PIPJ dislocations.
  • Men constituted 76% of cases, with dislocations predominantly affecting the little (43%) and ring (34%) fingers.
  • Dorso-ulnar (49%) and dorsal (41%) dislocations were most common. Six open dislocations occurred, primarily affecting the index and middle fingers.

Conclusions:

  • PIPJ dislocations present in two main groups: young men (sports-related, little finger) and older adults (falls, middle finger).
  • Open dislocations are typically dorsal and involve the index or middle fingers.
  • Follow-up rates varied significantly, suggesting approximately 20% of patients may experience prolonged symptoms.
