Epiphysiolysis

Epiphysiolysis (Epiphyseal Dislocation) is a dystosia of the epiphysis that occurs as a result of injury or disease of the skeleton, manifested by loss of contact of the lower part of the fibrous capsule of the epiphyses with the articular surfaces of the legs and thighs. Typically, injury or illness causes the patella to become loose. The developing defect of the primary center leads to degenerative-dystrophic changes, which consist in a decrease in the interepiphyseal zone, hypotrophy, and hardening of the epiphysis. As a result, the epiphysis is weakly attached to the surface of the tibia. Subsequently, the epiphysis moves along



Epiphysiolysis is a disorder of the ossification process that occurs after a fracture of the leg bones due to the decomposition and resorption of the hyaline cartilage (epiphysis) of the bone head. At the initial stage, the syndrome manifests itself as a dysfunction of the foot, which can result in rachitic lameness and deforming arthrosis of the joint. But since this syndrome is quite rare, such damage can be confused with intra-articular complications of a fracture, although it impairs bone growth and significantly reduces its performance. Epiphysiolysis typically occurs in the distal femur in the area of ​​the scaphoid or cuboid bone and the proximal tibia, most often in the ankle area. In childhood, these are rare fractures that occur as a result of indirect injuries (jumping, diving, roller skating, cycling). In this case, a pathological fracture is formed with the formation of secondary epiphyses, which form when the lower surfaces of the metaphysis (bone ends) are bent, which is accompanied by frequent shortening of the affected lower limb and a pronounced violation of its trophism. This occurs due to the occurrence of chromotrophic processes that occur in the tendons of the muscles that attach to the lower leg. And pronounced trophic lameness develops after a fracture of the limb bone and depends on whether there is a pathological fracture and whether its immobility is preserved. The proximal type of epiphysiosis is much less common in children than the distal one. The reason for the development of this process does not differ from the mechanism of development of distal epiphysialis. It can be localized in the condyles of the femur and the head of the humerus. Given the rare occurrence of this syndrome, it is often confused with traumatic
