Summary
This study introduces an arthroscopic coracoclavicular (CC) fixation technique for acute acromioclavicular (AC) joint dislocations. The technique showed satisfactory clinical and radiologic outcomes, emphasizing the importance of initial CC distance recovery for maintaining AC joint position.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Traumatology
Background:
- Acromioclavicular (AC) joint dislocations are common shoulder injuries.
- High-grade AC dislocations often require surgical intervention to restore stability.
- Arthroscopic techniques offer potential advantages in minimally invasive treatment.
Purpose of the Study:
- To introduce and evaluate an arthroscopically assisted coracoclavicular (CC) fixation technique.
- To assess the clinical and radiologic outcomes of this technique in patients with acute high-grade AC joint dislocations.
- To investigate the impact of initial reduction and fixation on long-term outcomes.
Main Methods:
- A case series of 27 patients with acute high-grade AC joint dislocations treated with arthroscopic CC fixation using multiple low-profile devices.
- Minimum follow-up of 24 months.
- Radiologic assessment included vertical coracoclavicular distance (CCD) and horizontal displacement; clinical outcomes were measured using the Constant-Murley score.
Main Results:
- The arthroscopic CC fixation technique demonstrated a significant reduction in CCD immediately postoperatively.
- While some increase in CCD was observed at final follow-up, horizontal displacement remained minimal.
- Patients with excellent initial CCD recovery showed significantly better maintenance of AC joint position compared to others.
Conclusions:
- Arthroscopic CC fixation with multiple low-profile devices provides satisfactory clinical and radiologic outcomes for acute high-grade AC joint dislocations.
- Achieving good initial CC distance recovery is crucial for maintaining the AC joint's proper position.
- Precise placement of fixation devices is important for long-term stability.

01:16Structural 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...

01:03Structural 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...

01:17Structural 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, 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

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...

01:30Method of Joints
1.3K
The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint.
Since plane truss members are in the same plane, each joint is subjected to a coplanar and concurrent force system. To apply the method of joints, the first step is to...
