What does it mean if the 50 cm femur and the epiphyseal discs are completely ossified?

50cm is about the length of an adult - and when a bone is completely ossified, that means that bone has stopped growing.

What does the femur load number mean?
During crash tests and safety checks they test to see how much pressure the femur can hold before it fractures. I think they said that it can hold up to 500lbs of pressure before it fractures. Therefore, if your car says that it has a femur load of 244lbs for example, then that is how much pressure will likely to be applied to your femur during a certain pertaining crash.
Why humerofemoral index is calculated?
dividing the length of the humerus by the length of the femur, and multiplying by 100.
What is one and one-half hip spica cast?
n orthopedic cast that covers the trunk cranially to the nipple line, one leg caudally as far as the toes, and the other leg caudally as far as the knee. For stability, a diagonal crossbar connects the parts of the cast encasing the legs. This type of cast is used for immobilization during healing of a fractured femur or after surgical hip repair or for correction and maintenance of the correction of a hip deformity.
Describe Bryant's triangle its importance in orthopaedics?
Bryant's triangle is to be drawn while the patient is lying on his back. One side is a perpendicular let fall from the anterior superior spine to the table, the other side is one joining the anterior superior spine and the tip of the greater trochanter, the base is a line running horizontally from the tip of the greater trochanter to the perpendicular line. If the tip of the trochanter becomes elevated, as in fractures of the neck of the femur, it shortens the base of the triangle on the affected side as compared with the base of the triangle on the sound side.
How does a forensic anthropologist use math?
Forensic anthropologists use data gathered through anthropometric/osteometric methods to draw conclusions. For example, say they have the femur (thigh bone) of an unknown victim and they want to estimate that victim's height. The person can measure the femur, and then plug that measurement into a formula to give a rough estimate of the victim's height. The formula used is created by analyzing a huge osteometric database that contains measurements of the femur in individuals of known height. This is how they create the most accurate estimate. Of course, the quality of these databases varies, but the goal is always to use the most recent, most complete data possible. Luckily, much of this work is now done by computer software, which is a great time saver for the forensic anthropologist. However, it is still important to understand the math behind the software, and to be able to explain how it works to a jury. There are also mathematical formulas used to calculate decomposition rates which take into account temperature, but usually these are included. They are used to complement a more holistic analysis that takes into account unquantifiable factors, such as animal scavenging, perimorterm trauma, etc. Forensic anthropologists must also understand concepts in math. For example, you must be able to tell whether the sub pubic angle is greater than or less than 90 degrees, as this can help to determine whether the pelvis you're looking at is male or female. It's absolutely crucial to understand the significance of sample size in a study--this can help you determine whether the conclusions drawn from the study should be applied to your case, or whether more research is needed before you can draw a conclusion. Statistics in general are important--frequency plots, frequency distributions, and big tables full of numbers can be found in almost any journal article on forensic anthropology. Digital imaging advances are now allowing forensic anthropologists to analyze skeletal features mathematically, and therefore, more objectively. Increasing objectivity in forensic anthropology is very important, especially when the forensic anthropologist's conclusions have to hold up in court. It's easy to argue with the opinion that a skull has "delicate features" and is therefore probably female, but it's much harder to argue with osteometric measurements that give you an 88% likelihood the skull is female.
Can you see an epiphyseal plate on a open dried femur bone?
Not if it is a femur from a skeletally mature individual. The epiphyseal plate of the femur closes at around age 17 or 18. After this age, you would not see the epiphyseal plate, but you should be able to see the physis (or physeal) scar. This is the point at which the epiphysis and metaphysis have fused.
What bones in a fetus has ossified at birth?
lower end of femur, upper end of tibia, calcaneus, talus and cuboid have ossified by birth.Among them the lower end of femur, calcaneus and talus are more persistent.
How could x-rays of the femur be used to determine whether a person had reached full height?
once you are done growing, your epiphyseal plates (growth plates) which are cartilage, become ossified and turn to bone. If you still have the cartilage, you are not done growing. If it is all bone, you are.
Where do long bones lengthen?
Long bones such as the femur length along the epiphyseal plate that turns into the epiphyseal line in adults when their growth is complete.
Articulates with the coxal bone?
The femur :)
Which ossification method would form a femur?
The femur is formed through the endochondral ossification process. This is where bone replaces the cartilage. There are six steps in this type of ossification and they are as follows; one the development of cartilage model, two the growth of the cartilage model, three the development of the primary ossification center, four the development of the medullary cavity, five the development of the secondary ossification centers, and six the formation of articular cartilage and the epiphyseal plate.
What does femur mean?
The Femur is the bone that goes from your hip down to your knee. Femur length would mean how long the Femur is.
