How to Identify and Resolve Common Issues ?

We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :

Where is the femur located? The femur is the only bone in your thigh. It runs from your hip to your knee.
The femur or thigh bone is found in the upper leg and is the longest bone in the body. The femur articulates proximally with the acetabulum of the pelvis to form the hip joint, and distally with the tibia and patella to form the knee joint.
Inside the body of the femur is the medullary cavity, which contains bone marrow. At the ends of the femur are areas of compact bone, which is solid and does not contain marrow. Surrounding the compact bone is spongy bone, which has lots of small cavities dispersed throughout it.
The thigh bone, or femur, is the large upper leg bone that connects the lower leg bones (knee joint) to the pelvic bone (hip joint).
The thigh bone (femur) is a long bone. A long bone has a shaft and two ends. Some bones in the fingers are classified as long bones, even though they are short in length.
The origin of bone. Precipitation of hydroxyapatite around the basal membrane of the skin gave rise to enamel- and dentine-like tissues that formed odontodes, which became the progenitors of teeth and scales. Spread of mineralization deeper in the dermis formed shields consisting of acellular—and later cellular—bone.
The femur tends to roll backwards with flexion. The combination during flexion of no anteroposterior movement medially (i.e., sliding) and backward rolling (combined with sliding) laterally equates to internal rotation of the tibia around a medial axis with flexion.
The femur is classified structurally as a long bone and is a major component of the appendicular skeleton. On its proximal end, the femur forms a smooth, spherical process known as the head of the femur. The head of the femur forms the ball-and-socket hip joint with the cup-shaped acetabulum of the coxal (hip) bone.
The two femur bones serve as pillars in our legs that allow us to walk, run, jump, and make all kinds of other movements.
The quadriceps include four large muscles, rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. The quadriceps femoris is one of the strongest muscle groups in the body that covers the anterior aspect of the femur. This group of muscles has a common function. They extend the leg at the knee joint.
femur ​Definitions and Synonyms

A less technical name for this is the thigh bone.

It forms part of the hip (at the acetabulum) and part of the knee. The word femur is Latin for thigh. Theoretically in strict usage, femur bone is more proper than femur, as in classical Latin femur means “thigh”, and os femoris means the bone within it.
Bone is composed of four different cell types; osteoblasts, osteocytes, osteoclasts and bone lining cells.
The femur is one of the most well-described bones of the human skeleton in fields ranging from clinical anatomy to forensic medicine. Because it is the longest and strongest bone in the human body, and thus, one of the most well-preserved in skeletal remains, it makes the greatest contribution to archaeology.
The long bone category includes the femora, tibiae, and fibulae of the legs; the humeri, radii, and ulnae of the arms; metacarpals and metatarsals of the hands and feet, the phalanges of the fingers and toes, and the clavicles or collar bones.
There are two major modes of bone formation, or osteogenesis, and both involve the transformation of a preexisting mesenchymal tissue into bone tissue. The direct conversion of mesenchymal tissue into bone is called intramembranous ossification. This process occurs primarily in the bones of the skull.
So the Greek scholars, and later Roman and medieval scholars, named bones and organs and muscles after what they looked like.
The femur is the longest, heaviest, and strongest bone in the human body. The main function of the femur is weight bearing and stability of gait. An essential component of the lower kinetic chain.
Ultimate Strength of the Femur

For example, the ultimate compressive strength for human femur bone is measured to be 205 MPa (205 Million Pascals) under compression along its length. The ultimate tensile strength of femur bone under tension along its length is 135 MPa.

It starts below the hip and ends at the knee where the bone begins to widen. This hollow portion of the bone is about an inch and a half thick and has a rounded shape on either end. On the femur`s upper end (proximal aspect) are the femoral head and neck.
Congenital short femur is a rare type of congenital malformation that occurs during prenatal development and affects the growth of the femur bone in the upper leg.
In general, the bone is loaded axially, rather than in bending, with maximum shear forces at the proximal and distal ends. Bending moments are relatively small compared to models which do not consider muscle activity. From one gait phase to another, the femur experiences alternating, rather than one-sided bending load.
During the last 30 degrees of knee extension, the tibia (open chain) or femur (closed chain) must externally or internally rotate, respectively, about 10 degrees. This slight rotation is due to inequality of the articular surface of femur condyles.
The average femur weight for a human male is about 290 grams. The average weight of the femur for a human female is slightly less at about 260 grams.
