The calcar femorale is a vertical plate of bone lying deep to the lesser trochanter and is formed as a result of traction of the iliopsoas which separates the femoral cortex into two distinct layers, the calcar femorale and the medial femoral cortex. They fuse together proximally to form the medial femoral neck.
What is calcar bone?
The calcar is a vertical plate of dense cancellous bone which lies deep to the lesser trochanter but posterior to the neutral axis of the femoral neck.
What is the function of calcar femorale?
The calcar femorale can bear compression load and redistributes stress or load from the femoral head to the proximal femur. The calcar femorale also contributes to the strength of the femoral neck. Bigelow described the calcar femorale as ‘the true neck of the femur’.
Is a femur bone?
The femur (thigh bone) is the largest bone in your body. The femur is the only bone in the upper portion of your leg, and it is completely covered by your thigh muscles. These include the quadriceps (quads) in the front of your thigh, hamstrings in the back, gluteal muscles, and groin muscles (adductors).
What is the calcar of humerus?
The humeral calcar refers to the inferomedial cortical area where the humeral head extends to the surgical neck of the humerus. Morphological and microstructural analysis of the proximal humerus shows that this area is the best in terms of the thickness and density of the cortical bone.
Where is the ischial?
hip bone The ischium is the lower and back part of the hip bone Forming the lower and back sides of the hip bone, the ischium is one of the three bones that make up the pelvis. It is located beneath the ilium and behind the pubis.
What is Calcar Avis?
The Calcar avis is a mound of white matter formed by the development of the calcarine fissure. This fissure begins to develop at 16 weeks of gestation and extends progressively deeply from the medial aspect of the occipital lobe towards the occipital horn of the lateral ventricles.
What is linea aspera?
The linea aspera is a longitudinally-oriented ridge on the posterior aspect of the femur to which several muscles of the thigh attach. It is comprised of medial and lateral lips which diverge at both its superior and inferior ends.
What is a Hemi in orthopedics?
Hemi-means half and -arthroplasty means joint replacement. A hemiarthroplasty is a rare surgery that is only performed under unique circumstances. Replacing half of a hip joint is usually done after rare traumatic injury in which the femoral head is fractured.
What is a DHS surgery?
Dynamic hip screw (DHS) or Sliding Screw Fixation is a type of orthopaedic implant designed for fixation of certain types of hip fractures which allows controlled dynamic sliding of the femoral head component along the construct.
What is subtrochanteric femur fracture?
Subtrochanteric fractures are proximal femur fractures located from the lesser trochanter to 5cm distal to it that may occur in low energy (elderly) or high energy (young patients) mechanisms.
What attaches to the intertrochanteric line?
The joint capsule of the hip and the iliofemoral ligament insert on the intertrochanteric line. Furthermore, the vastus medialis muscle originates from the inferior portion of the intertrochanteric line.
How does femur break?
Motor vehicle accidents, sports-related injuries, gunshot injuries, and falls are common sources of trauma that can lead to a femur fracture. A direct blow to your hip may break the part of the femur associated with your hip joint. Most people with a fractured femur need some sort of surgery, usually ORIF.
How painful is a femur break?
How Does It Feel? A femur fracture may cause extreme pain in the upper leg area or hip area. It also may cause lesser pain in the buttocks, knee, thigh, groin, or back.
Where is a femur located?
thighbone femur, also called thighbone, upper bone of the leg or hind leg. The head forms a ball-and-socket joint with the hip (at the acetabulum), being held in place by a ligament (ligamentum teres femoris) within the socket and by strong surrounding ligaments.
Is pubic Ramus part of hip?
What we commonly call our hip bones are actually each three separate bones: the pubis, the ischium, and the ilium. The pubis itself is made up of two smaller bones: the superior ramus and the inferior ramus.
Why is it called the ischium?
Adoption of ischium into English-language medical literature dates back to c. 1640; the Latin term derives from Greek iskhion meaning hip joint.
What is the pubic crest?
Medical Definition of pubic crest : the border of a pubis between its pubic tubercle and the pubic symphysis.
Where is the collateral eminence?
The collateral eminence is an elongated swelling lying lateral to and parallel with the hippocampus. It corresponds with the middle part of the collateral fissure, and its size depends on the depth and direction of this fissure.
What part of the brain contains lateral ventricles?
Lateral ventricles are two c-shaped cavities one on each side of cerebral hemisphere. It consists of a central part called body and three extensions: anterior (frontal horn), posterior (occipital horn), and inferior (temporal horn).
Which of the following structures forms the lateral wall of the body of the lateral ventricle?
The frontal horn (Fig 1) extends anteriorly from the foramina of Monro and communicates with the body of the lateral ventricles posteriorly. The anterior wall and roof are formed by the genu of the corpus callosum, and the floor is formed by the rostrum. The head of the caudate nucleus forms the lateral wall.
What is the adductor magnus?
The Adductor Magnus muscle is one of six muscles in the medial compartment of the thigh. Adductor Magnus is a broad triangular muscle forming a septum which divides the anterior muscles from the posterior aspect of the thigh. It is the largest muscle in the medial compartment.
What is the gluteal tuberosity?
Medical Definition of gluteal tuberosity : the lateral ridge of the linea aspera of the femur that gives attachment to the gluteus maximus.
What is the adductor brevis?
The adductor brevis is a muscle in the thigh situated immediately deep to the pectineus and adductor longus. It belongs to the adductor muscle group. The main function of the adductor brevis is to pull the thigh medially.
What is Hemi hip arthroplasty?
Hip hemiarthroplasty is a procedure used to treat hip fractures that is like a total hip replacement but only part of the hip is replaced. While this procedure is used to treat hip fractures, it is also used to treat hip arthritis.
Can femoral neck be replaced?
This procedure is used if the end of the bones is damaged or displaced. It involves removing the head and neck of the femur and replacing it with a metal prosthesis. Partial hip replacement may also be recommended for adults with other serious medical conditions, rather than a total hip replacement.
What is bipolar prosthesis?
A bipolar prosthesis has an additional artificial joint between the two components of the prosthesis. Both treatments are clinically proven and common around the world. No clinical trial has proven benefits of one or the other prosthesis design.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
