Summary
Symptomatic osteoarthritic coracoclavicular joint (CCJ) is a rare cause of shoulder pain. Therapeutic injection provided significant pain relief, highlighting CCJ as an underrecognized diagnosis.
Area of Science:
- Orthopaedic Surgery
- Radiology
- Pain Management
Background:
- The coracoclavicular joint (CCJ) is an uncommon source of shoulder pain.
- Limited information in orthopaedic literature contributes to underdiagnosis.
- Awareness of symptomatic CCJ is low within the medical community.
Purpose of the Study:
- To increase awareness of the coracoclavicular joint as a cause of shoulder pain.
- To present a case of symptomatic osteoarthritic CCJ.
- To discuss diagnostic radiological signs of CCJ.
Main Methods:
- Case report of a 46-year-old male patient with shoulder pain.
- Diagnostic imaging to identify CCJ pathology.
- Therapeutic injection into the CCJ for pain management.
Main Results:
- The patient presented with symptoms attributed to osteoarthritic CCJ.
- Radiological signs suggestive of CCJ pathology were observed.
- Therapeutic injection resulted in nearly complete pain relief.
Conclusions:
- Symptomatic osteoarthritic CCJ can be a cause of shoulder pain.
- Therapeutic injection is an effective treatment for CCJ pain.
- Increased awareness and understanding of CCJ radiological signs are needed.

Ankle Joint
2.0K
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...

Structural Joints: Synovial Joints
4.7K
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: Cartilaginous Joints
2.8K
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...

Knee Joint
2.4K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Muscles of the Shoulder
7.0K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Pleural Effusion II: Symptoms and Management

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
