What is a Pellegrini Stieda lesion?
Introduction. Pellegrini-Stieda lesions, named after early twentieth century Italian and German surgeons Augusto Pellegrini and Alfred Stieda, are defined as ossifications of the medial collateral ligament (MCL) at or near its proximal insertion on the medial femoral condyle.
What is Pellegrini?
The Pellegrini–Stieda sign is a calcification of the medial collateral ligament of the knee after trauma. The presence of symptoms associated with radiological findings is known as Pellegrini–Stieda syndrome. Pain is the main element that characterizes the disease.
What is an MCL injury?
An MCL injury is a sprain or tear to the medial collateral ligament. The MCL is a band of tissue on the inside of your knee. It connects your thighbone to the bone of your lower leg. The MCL keeps the knee from bending inward.
What is a femoral condyle?
The femoral condyles are located on the end of the thigh bone, or the femur. They are covered by articular cartilage and function as a shock absorber for the knee.
What is a Stener lesion?
A Stener lesion is a complete tear of the ulnar collateral ligament (UCL) from the thumb proximal phalanx at the level of the metacarpophalangeal (MCP) joint that is displaced superficial to the adductor pollicis aponeurosis, leading to interposition of the aponeurosis between the UCL and the MCP joint.
Where does the MCL attach?
The MCL originates on the medial aspect of the distal femur and inserts on the medial aspect of the proximal tibia several centimeters below the joint line. Its deep fibers are intimately interlaced with the joint capsule at the level of the joint, and the medial meniscus is attached directly to it.
What is the difference between meniscus and MCL?
MCL stands for medial collateral ligament and is located on the inside of the knee. The MCL originates on the femur (thigh bone) and inserts on the tibia (large bone of the lower leg). The MCL splits slightly at the knee joint and some fibers also insert onto the medial meniscus (cushion inside the knee).
Do you need surgery for a torn MCL?
MCL Treatment Since Grade III MCL injuries are complete tears, the ligament is unable to heal itself and surgery is needed. Surgery may also be needed if there is any grade of an MCL tear along with other ligament issues.
What does condyle mean in medical terms?
Definition of condyle : an articular prominence of a bone especially : one resembling a pair of knuckles.
What does a condyle do?
condyle A smooth round knob of bone that fits into a socket on an adjoining bone, forming a joint. Such a joint permits up-and-down or side-to-side movement but does not allow rotation. There are condyles where the lower jawbone (mandible) is attached to the skull, which permits chewing movements.
Where are Pellegrini Stieda lesions located on the body?
Pellegrini-Stieda lesion. Dr Henry Knipe ◉ ◈ and Dr Behrang Amini et al. Pellegrini-Stieda lesions are ossified post-traumatic lesions at (or near) the medial femoral collateral ligament adjacent to the margin of the medial femoral condyle.
How to tell if you have Pellegrini Stieda syndrome?
Pellegrini-Stieda lesion 1 Clinical presentation. Most patients are asymptomatic while a small proportion will have medial knee pain ( Pellegrini-Stieda syndrome ). 2 Radiographic features. 3 Treatment and prognosis. 4 History and etymology. 5 Differential diagnosis
Where does the calcium deposit develop in Pellegrini Stieda syndrome?
This calcium deposit develops between the attachment of the medial collateral ligament and medial condyle. The radiographic finding of the lesion is termed Pellegrini–Stieda phenomenon/lesion/sign, whereas the combination of the radiographic anomaly at the designated location with pain at that site is known as Pellegrini–Stieda syndrome.
