It may occur as a complication of infection or trauma involving the epiphyseal cartilage plate (2). Compact bone makes up most of the bone of the diaphysis while spongy bone makes up most of the epiphysis. Epiphyseal cartilage is a type of cartilage found at each end of a long bone related to bone elongation, or growth. There’re two growth plates in all long bones with one located at each end of the long bone. Simply put, the epiphyseal / growth plates are thin layers of cartilage disc entrapped at the distal ends of long bones between the epiphysis (head ) and metaphysis . While epiphyseal fusion of long bones has been studied for age estimation since a long time, over the past few years, the role of medial clavicular epiphyseal fusion in age estimation is being explored. The estimation of age at death using epiphyseal union is one of three primary approaches to aging subadult remains, the other two being dental development and eruption, and long bone growth. The ages of which epiphyseal fusion begins and ends are very well documented, with the majority of epiphyseal activity taking place between the ages of fifteen and twenty-three. Longitudinal growth occurs within the long bones at the growth plate. Intramembranous ossificationis the process of bone development from fibrous membranes. calcium and phosphorus calcium and iron iron and phosphorus calcium and iodine calcium and sodium. Complete fusion in males occurs as early as 14 years in both epiphyses.

The growth plate itself is made up of a scaffold of cartilage. Injury typically: The growth plate of bones can close (fuse) too early. Over the course of adolescence the epiphysis, which is originally separate, will fuse to the diaphysis. Summary of BONE CELLS. Results indicate that complete fusion in females occurs as early as 12 years in the distal tibia and fibula. 10. The expanded surface of the semi-rigid, calcified tissue is covered with articular cartilage that separates it from an epiphyseal plate-like structure called subchondral bone. Disorganization of chondrocyte columns in the growth plate does not aggravate experimental osteoarthritis in mice. All males demonstrated complete fusion by 19 years. Each bone has a predictable age range when long bone fusion occurs; in fact, different ends of the bone each have their own individual range. Epiphyseal cartilage is a type of cartilage found at each end of a long bone related to bone elongation, or growth.

The epiphyseal plate is comprised of cartilage that reproduces rapidly to lengthen the bone, with the rate of new bone production outstripping the rate of bone destruction. In the picture above, forensic anthropologist Dr. Bill Bass holds two bones ― an infant and an adult human femur. Epiphyseal fusion in the human growth plate does not involve classical apoptosis. Kang BH, Cho JH, Kim SY, Jeong KA, Kim SH, Kim C, Lim SJ, Shim KS. A long bone begins in the fetus as a hyaline cartilage model, then the time of birth a secondary center of ossification or epiphysis develops at each end of the developing long bone. The growth plate: a physiologic overview. At skeletal maturity, growth ceases when the epiphyses fuse with the diaphyses, indicating that all the cartilage has been replaced with bone and epiphyseal closure has been achieved. Examples of epiphyseal closure in the following topics: Postnatal Bone Growth. Epub 2009 Apr 29.
