Summary
Osteochondroma, a common benign bone tumor, typically affects the limbs. This case highlights their occurrence in unusual locations, emphasizing the need for thorough radiographic evaluation before surgery.
Area of Science:
- Orthopedic Oncology
- Skeletal Radiology
Background:
- Osteochondroma is the most frequent benign bone tumor, originating from aberrant cartilage of the perichondral ring.
- Commonly found in the proximal humerus, femur, and knee, it can be solitary or multiple in hereditary multiple exostoses.
Observation:
- This study presents a unique case of osteochondroma in an atypical location.
- The case underscores the potential for osteochondromas to manifest in unexpected anatomical sites.
Findings:
- Osteochondromas are generally benign, with malignant transformation occurring in about 1% of cases.
- Symptoms typically include localized pain and swelling.
Implications:
- Accurate radiographic visualization is crucial to assess tumor extent and involvement of surrounding structures.
- Pre-operative imaging is essential for effective surgical planning and management of osteochondromas, regardless of location.

01:16Structural Joints: Synovial Joints
6.4K
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
3.6K
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...

01:17Structural 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...

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.

00:58Introduction 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...

01:10Ankle 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...
