What is the metaphysis of the femur?

The metaphysis is the neck portion of a long bone between the epiphysis and the diaphysis. It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses….

What is distal femoral?

The distal femur is the area of the leg just above the knee joint. Distal femur fractures most often occur either in older people whose bones are weak, or in younger people who have high energy injuries, such as from a car crash.

What is the metaphysis of a bone?

The metaphysis is the region where the epiphysis joins the diaphysis; in a growing bone this corresponds to the calcified layer of the epiphyseal plate together with the interdigitating bone (see Figure 4.19). The interface between the hypertrophic and calcified layers is sometimes referred to as the tidemark.

Where is the metaphysis located?

The metaphyses (singular: metaphysis) are the wide portions of long bones and the regions of the bone where growth occurs. Growth occurs at the section of the metaphysis that is adjacent to the growth plate (physis). The metaphysis is located between the diaphysis and epiphysis.

What is definition of metaphysis?

me•taph•y•ses (-sēz′) The zone of growth between the epiphysis and diaphysis during development of a bone.

Why is metaphysis important?

function in bone structure This region (metaphysis) functions to transfer loads from weight-bearing joint surfaces to the diaphysis. Finally, at the end of a long bone is a region known as an epiphysis, which exhibits a cancellous internal structure and comprises the bony substructure of the joint surface.

How long does a distal femur take to heal?

Depending on health and injury pattern this bone can take 3-4 months to heal without surgery. Physical therapy for knee range of motion is started around 6 weeks once bone has healed enough to prevent displacement with motion.

Where is distal femoral diaphysis?

The distal femur is defined as the region from the metaphyseal-diaphyseal junction to the articular surface of the knee, involving approximately the distal 15 cm of the femur.

Is metaphysis present in adult?

In the adult, only the metaphysis and diaphysis are present (Figure 1). Figure 1: Anatomical differences between adult and child bone. The epiphysis is completely or mostly cartilaginous in infants.

Is metaphysis present in adults?

Can a distal femur fracture heal without surgery?

Very few distal femur fracture patterns and types do not need surgery for the bone to heal. This is because the strength of muscles that pull on the bones trying to pull them apart. Small breaks or those with good overall alignment often can be treated without an operation.

How long do you stay in hospital after femur surgery?

The average time from arrival to surgery was 17 hours. The average time from surgery to physical therapy was 1.3 days. Patients who had surgery more than 24 hours after arrival stayed longer. Patients requiring placement stayed 2.4 days longer until placement was found.

How long does it take for a distal femur to heal?

General Treatment Most distal femur fractures are treated with surgery. The broken bone will take a minimum of 2 months to heal. Some can take more than 6 months to heal. Surgery may take place anywhere from 1-5 days after your injury.

Which of the following describes the metaphysis?

The correct answer is c – the region of a long bone between the end of the bone (known as the epiphysis) and the shaft (known as the diaphysis) is the metaphysis.

Why is infection common in metaphysis?

Hematogenous osteomyelitis is the most frequent type and primarily affects the metaphysis because the bacteria travel through vascular tunnels and adhere to the bone matrix. Animal models show that bone infection becomes more likely after trauma.

How many hours does femur surgery take?

The surgeon makes a surgical cut on the side of your thigh. The metal plate or nail is attached with a few screws. This surgery takes 2 to 4 hours.

Is femur surgery serious?

A broken femur is a serious injury that requires immediate medical care. Broken femurs are treated with surgery and physical therapy. It can take months for your broken femur to heal.

What happens if a bone infection goes untreated?

What is osteomyelitis? Osteomyelitis is a bone infection caused by bacteria or fungi. It causes painful swelling of bone marrow, the soft tissue inside your bones. Without treatment, swelling from this bone infection can cut off blood supply to your bone, causing bone to die.

Where is the distal femoral metaphysis located?

Where is the distal femoral metaphysis? It is classically, located in the medullary cavity of long bone epiphyses, and apophyses, and it is rarely, found in the cortex of the long bone metaphysis. We describe a chondroblastoma in the cortex of the distal femur metaphysis, and emphasize imaging findings, and differential diagnosis.

What is a distal femur?

The distal femur is where the bone flares out like an upside-down funnel. The distal femur is the area of the leg just above the knee joint. Similarly, how long does a distal femur take to heal?

What does metaphysis mean in anatomy?

Increased width of the distal part of the shaft (metaphysis) of the femur. [from HPO] Explore related conditions in hierarchy to find additional content.

What are the indications for distal femoral replacement?

Distal femoral replacement is indicated as a revision procedure in patients with severe comminuted periprosthetic fractures who have associated implant failure, antiquated implants or osteopenic bone, and is indicated for catastrophic revision scenarios such as cases of severe lysis, ligamentous instability or extensor
