Three types of FAI are recognized (see title image). The first involves an excess of bone along the upper surface of the femoral head, known as a cam deformity (abbreviation for camshaft, which the shape of the femoral head and neck resembles). The second is due to an excess of growth of the upper lip of the acetabular cup and is known as a ...
Necrotic bone and inflammation histology slide. The current etiology or origin of this disease is unknown. Some studies theorized that bone remodeling is maintained in a microenvironment in the FH meaning that there is a greater local component to changes to the femoral head than the normal systemic way that bone remodeling is handled throughout the body.
No osteoarthritis signs 1: Mild: increased osteosclerosis; minor joint space narrowing (normal joint space is at least 2 mm at the superior acetabulum) [7] no or minor loss of head sphericity; 2: Moderate: small bone cyst; moderate joint space narrowing; moderate loss of head sphericity; 3: Severe: large bone cysts
The medial circumflex femoral artery is the principal source of blood supply to the femoral head. LCP disease is a vascular restrictive condition of idiopathic nature. Symptoms like femoral head disfigurement, flattening, and collapse occur typically between ages four and ten, mostly male children of Caucasian descent.
In radiology, the crescent sign is a finding on conventional radiographs that is associated with avascular necrosis. [1] [2] [3] It usually occurs later in the disease, in stage III of the four-stage Ficat classification system. [1] It appears as a curved subchondral radiolucent line that is often found on the proximal femoral or humeral head. [1]
Post-traumatic osteoarthritis is the most common variation of post-traumatic arthritis. [3] Between 20 and 50% [4] of all osteoarthritis cases are preceded by post-traumatic arthritis. Patients having post-traumatic osteoarthritis are usually younger than osteoarthritis patients without any previous physical injuries. [5]
Klein's line or the line of Klein is a virtual line that can be drawn on an X-ray of an adolescent's hip parallel to the anatomically upper edge of the femoral neck.It was the first tool to aid in the early diagnosis of a slipped capital femoral epiphysis (SCFE), which if treated late or left untreated leads to crippling arthritis, leg length discrepancy and lost range of motion.
Several approved drugs are being investigated as repurposed agents in the treatment of osteoarthritis such as liraglutide (anti-diabetic and anti-obesity drug: NCT02905864), Metformin (anti-diabetic drug: NCT04767841, NCT05034029), Zoledronic acid (anti-osteoporotic drug: NCT04303026), etc. [4] Paroxetine has been deemed to have DMOAD activity ...
