For preoperative planning I always make a CT. The graft was harvested from the medial or lateral talar articular facet on the same side of the lesion. He has ongoing pain, swelling. 10 0 obj Osteochondral lesions (OCLs) of the tibial plafond (OLTPs) are rare, and few studies provide treatment recommendations. The prevalence of osteochondritis dissecans in the tibial plafond detected on radiography is unknown. <>stream Pain Physician. endstream The top of the talus is dome-shaped and is completely covered with cartilage—a tough, rubbery tissue that enables the ankle to move smoothly. x�]�� Nine patients had isolated lesions, while four had lesions of the distal tibial plafond and talar dome.

Comparison of sagittal (A, B) and coronal (C, D) T2 fat-saturation images of the left ankle showing separation of the osteochondral fragment from the posterior tibial plafond with a fluid cleft and increased surrounding marrow edema at follow-up (June 21, 2017). The treatment of osteochondral injurie sof the ankle has been studied for at least four decades. In this case report, we reported a rare case of osteochondritis dissecans located on the medial tibial plateau. The tibia and fibula bones sit above and to the sides of the talus, forming the ankle joint.

Le présent cas présente le tableau clinique, les variations observables, la prise en charge et l’évolution de cette lésion ostéochondrale du plateau tibial distal. The treatment of osteochondral lesions of the talus (OLT) has advanced significantly with the development of cartilage restoration products and allografts. BACKGROUND: Osteochondral lesions of the distal tibial plafond (OLTPs) are an uncommon problem. (A) Axial MRI Proton Density; (B) Sagittal MRI T1-weighted; (C) Sagittal MRI Fat-suppressed. Magnetic resonance imaging revealed an osteochondral lesion of the tibial plafond with no injury to the talar dome. L’examen par imagerie par résonance magnétique a révélé la présence d’une lésion ostéochondrale au dôme talien. She was treated by arthroscopy for her knee condition. The necrotic fragment usually becomes revascularised and reattaches to the surrounding bone. The cartilage can be torn, crushed or damaged and, in rare cases, a cyst can form in the cartilage. <>stream It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). Osteochondral defects (OCD) or lesions (OCL) are focal areas of damage with articular cartilage damage and injury of the adjacent subchondral bone plate and subchondral cancellous bone. History and previous treatment: Xrays- large cystic OCL in the anterior tibial plafond. Other terms that refer to the same general process are osteochondral defects (OCD), osteochondritis dissecans, and transchondral fracture. There are few cases describing this lesion in the literature, with little information on mechanism of injury, history/physical findings or recommendations for management. Foot Ankle Int. The talar dome is a trapezoid-shaped protuberance of the talus, 2.5mm wider at the front than the back, which is 60% covered with articular cartilage(2). <>>>/BBox[0 0 612 792]/Length 170>>stream %PDF-1.2 The oval is the starting point, each rectangle is a factor in the decision-making process, and each rhombus is a selected approach and end point Decision making is based on size, characteristics, and location of the lesion as well as type of surgical treatment.
