The fate of articular cartilage in traumatic dislocation of the hip
Abstract:
The right hips of 69 five-day-old rabbits were dislocated surgically and left to develop in the dislocated position to determine the nature and timing of changes in the hip. Using the left hips as controls, 15 survivors were killed and studied macroscopically and microscopically at two months of age and 14 at four months of age. It was found that articular cartilage of the acetabulum in the dislocated hips showed fibrous degeneration in about 50% of the two-month-old rabbits cases and in all of the four-month-old rabbits. In the dislocated femoral heads the articular cartilage was normal, and only 25% of the four-month-old animals showed fibrous degeneration.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Structural Joints: Cartilaginous Joints
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 or...

A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...
