How long does a subchondral fracture take to heal?
Since a recovery time of up to 3 years is documented for subchondral insufficiency fractures of the knee, the patient may have potential for further recovery.
What is a subchondral fracture of the femoral head?
Subchondral fracture of the femoral head is an uncommon entity and usually occurs as an insufficiency fracture associated with poor bone quality or as a fatigue fracture in young military recruits. 1. It is reported in elderly people and in recipients of renal transplants.
How do you get a subchondral fracture?
Subchondral insufficiency fractures (SIF) are a type of stress fracture which occurs below the cartilage on the weight bearing surface of a bone. SIF occur when normal physiological forces are repeatedly applied to an area of bone compromised by non-tumorous disease, resulting in fracture.
Can you run on a femoral stress fracture?
If you suspect a femoral stress fracture, get the runner non-weight bearing on two crutches, and get an expert opinion and an MRI scan. These patients will typically need six weeks of total off-loading, followed by lots of rehab. Looked after correctly, most patients will go on to return to running.
How do you fix a subchondral fracture?
Subchondroplasty is a technique indicated for treatment of early subchondral fractures or stress related marrow edema associated with osteoarthritis and involves the injection of synthetic calcium phosphate into the trabecular space, providing mechanical support.
How is a subchondral fracture treated?
Treatment and prognosis Joint preserving surgical treatments of subchondral fractures include microfracture, drilling, subchondroplasty 10, or in the hip joint: transtochanteric osteotomy 11. High-grade fluid-filled lesions with cortical collapse and severe osteoarthritis might require arthroplasty.
What is a femoral head fracture?
Fracture of the femoral head is a severe, relatively uncommon injury; typically, it occurs following traumatic posterior dislocation of the hip joint. The Pipkin classification is the most commonly used classification system.
How painful is a femoral stress fracture?
A stress fracture of the shaft of the femur is characterised by a dull ache felt in the front of the thigh that will develop over a period of weeks. The pain is often hard to localise and may even be felt in the knee.
Are femoral stress fractures common?
Stress fractures of the femur are relatively uncommon, and data from the literature suggest that they constitute only 2.8–7% of all sport related stress fractures.
What is a subchondral knee fracture?
Subchondral insufficiency fractures are non-traumatic fractures that occur immediately below the cartilage of a joint. Although low bone density may be present concurrently, it is not the underlying cause of subchondral insufficiency fractures in the majority of patients.
What does subchondral mean in medical terms?
“Subchondral bone” is bone that sits underneath cartilage in a joint. Subchondral bone is found in large joints like the knees and hips, as well as in small joints like those of the hands and feet. “Sclerosis” refers to an unusual increase in the density or hardness of a tissue in the body.
How is femoral head fracture treated?
Most fractures of the femoral head are treated surgically, given the tendency for these fractures to have displacement and joint incongruity. Operative treatment of displaced femoral head fractures can be either in the form of internal fixation or simple excision of the fracture fragments.
What causes a subchondral fracture of the femoral head?
Subchondral fracture of the femoral head has been reported to occur as an insufficiency fracture associated with poor bone quality or as a fatigue fracture in young military recruits.
Is there a stress fracture of the femoral head?
Subchondral stress fracture of the femoral head (SSFFH) is a rarely encountered condition.
Can a hip osteoporosis be a subchondral fracture?
Transient osteoporosis of the hip has clinicoradiological findings that mimic those of a subchondral fracture and is usually seen in healthy middle-aged people not involved in sports.3We present a rare case of subchondral fracture of the femoral head in an asymptomatic healthy adult that healed uneventfully.

Which is the differential diagnosis for a subchondral stress fracture?
Coronal (a,b) and sagittal (c,d,e,f) magnetic resonance imaging (T-1 and STIR image) showing subchondral marrow edema with a fracture line (marked with arrow and arrow head) The possible differential diagnosis was avascular necrosis, transient osteoporosis, and subchondral fracture.
