>10 mm Offset percentage Femoral head-neck offset related to femoral head diameter >0.18 less indicates high risk of cam type impingement; Tönnis angle Slope of the sourcil (the sclerotic weight-bearing portion of the acetabulum) 0 to 10° >10° is a risk factor for instability <0° is a risk factor for pincer impingement; Caput-sourcil angle [21]
Nevertheless, it can also occur during rest or without any weight-bearing. About 94% of the cases affect the medial condyle of the femur. This is because the blood supply for the medial condyle is less than the blood supply for the lateral condyle of the femur. The condition may deteriorate, causing asymmetrical walking or running pattern ...
Femoral head showing a flap of cartilage due to avascular necrosis (osteochondritis dissecans). Specimen removed during total hip replacement surgery. Specialty: Orthopedics: Symptoms: Joint pain, decreased ability to move [1] Complications: Osteoarthritis [1] Usual onset: Gradual [1] Risk factors: Bone fractures, joint dislocations, high dose ...
The lateral femoral cutaneous nerve (LFCN) is a purely sensory nerve, [3] [2] and consequently the symptoms are also sensory. [4] Symptoms are typically unilateral, seen in about 78% of cases, but may be bilateral. [4] [2] The most common symptom is pain, paresthesias, or dysthesias on the anterolateral surface of the thigh that extends just ...
Cortical desmoid (also known as a tug lesion or periosteal desmoid) is an irregularity of the distal femoral cortex that is caused by repetitive stress at the attachment of the adductor magnus aponeurosis. It is commonly observed in adolescents and is usually asymptomatic. This lesion is benign and tends to be self-limiting.
Patellofemoral pain syndrome can become a chronic injury, with an estimated 50% of people reporting persistent patellar-femoral pain after a year. [32] Risk factors for a prolonged recovery (or persistent condition) include age (older athletes), females, increased body weight, a reduction in muscle strength, time to seek care, and in those who ...
Alternative classification syndrome for Pellegrini-Stieda lesions of Type 1 through Type 4 based on their location: [2] Type 1- is referred to as a beak-like appearance and describes the ossification arising from the femur and extending inferiorly in the medial collateral ligament.
Unicameral bone cysts are found incidentally on X-rays. About 90 to 95% of the lesion is found in metaphysics of long bones. The cyst is centered, oblong in shape along the long axis of a long bone. Rarely, they are large and multicameral and are found in diaphysis.
