The typical changes seen on X-ray include: joint space narrowing, subchondral sclerosis (increased bone formation around the joint), subchondral cyst formation, and osteophytes. [54] Plain films may not correlate with the findings on physical examination or with the degree of pain. [55]
The simple bone cyst is a common, benign, fluid-containing lesion, most commonly found in the metaphysis of long bones, typically the proximal humerus or femur. Pathologic fractures are common, often with minor trauma. These cysts typically resolve after skeletal maturity and are not typically associated with bone tumors. The cause is unknown.
Medical condition Osteochondritis dissecans A large flap lesion in the femur head typical of late stage Osteochondritis dissecans. In this case, the lesion was caused by avascular necrosis of the bone just under the cartilage.

They may pass from the main joint cavity into a neighboring synovial cyst. For this reason, a mass may not be appreciated within the actual joint space itself. [citation needed] Additional radiographic findings include joint effusion and degenerative changes such as joint space narrowing, subchondral sclerosis, and osteophyte formation.
This area may be tender, meaning it is painful when pressed. There may also be hyperextension of the metacarpophalangeal joint. The thumb metacarpal deviates towards the middle of the hand (adduction). [12] Also a grinding sound, known as crepitus, can be heard when the TMC joint is moved, more so when axial pressure is applied. [13]
Benign cyst kidney; radiological appearances mimic renal cancer, A cyst / s ɪ s t / is a closed sac, having a distinct envelope and division compared with the nearby tissue.Hence, it is a cluster of cells that have grouped together to form a sac (like the manner in which water molecules group together to form a bubble); however, the distinguishing aspect of a cyst is that the cells forming ...
The capitate is the largest carpal bone found within the hand. [2] The capitate is found within the distal row of carpal bones. The capitate lies directly adjacent to the metacarpal of the ring finger on its distal surface, has the hamate on its ulnar surface and trapezoid on its radial surface, and abuts the lunate and scaphoid proximally.
Osteochondritis is a painful type of osteochondrosis where the cartilage or bone in a joint is inflamed. [1]It often refers to osteochondritis dissecans (OCD). The term dissecans refers to the "creation of a flap of cartilage that further dissects away from its underlying subchondral attachments (dissecans)".
