1976 Jan-Feb;(114):185–191. Talar dome lesions are usually caused by … A talar dome lesion can be difficult to diagnose because the precise site of the pain can be hard to pinpoint. Talar dome chondral and osteochondral lesions are a common cause of ankle pain and subjective instability. A partial fluid cleft at its posterior margin and a mild subchondral oedema suggests an unstable lesion. Management of symptomatic osteochondral lesions of the talus (OLT) is challenging given the poor healing potential of articular cartilage. Medline, Google Scholar Yvars MF.

Talar dome lesions are usually caused by … Two patients (a 16-year-old boy) had two recent osteochondral fractures, anterior and superior lateral, with a free fragment detached in the joint. If the cartilage doesn’t heal properly following the injury, it softens and begins to break off. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). Clin Orthop Relat Res. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. (B) Lesion debrided to stable margins. “Osteo” means bone and “chondral” refers to cartilage. incidence 69% of ankle fractures; 70% of ankle sprains; 10% are bilateral 2 of 7 Posadzy et al: Staging of Osteochondral Lesions of the Talus Figure 1: Location of the OCL according to the mechanism of trauma. Ankle Traction During MRI of Talar Dome Osteochondral Lesions. Smith GR, Winquist RA, Allan NK, Northrop CH. Talar Dome. We studied the value of MR imaging in determining the stability of the osteochondral fragments. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). Foot Ankle Int 1999; 20:474-480. Osteochondral lesions are injuries to the talus (the bottom bone of the ankle joint) that involve both the bone and the overlying cartilage. focal injuries to the talar dome with variable involvement of the subchondral bone and cartilage resulting in osteochondral lesion of the talus (OLT) may be caused by traumatic event or result of repetitive microtrauma; Epidemiology .
