MRI of osteochondral defects of the lateral femoral condyle: incidence and pattern of injury after transient lateral dislocation of the patella. Imaging Findings Conventional radiographs . 2. Ankle: 4 to 14 times more common in the talus (56% posteromedial, anteromedial 44%) than the tibial plafond. The aim of our study was to … Hepple S, Hepple WI, Hepple GD et-al. Radiographically, they are lucent defect traversing the length of epiphysis, and may have sharp or irregular borders. “Osteo” means bone and “chondral” refers to cartilage. This is essential in determining management. Kaplan P. Musculoskeletal MRI. Maeurer Juergen. However, coronal and sagittal images clearly show that the lesion originates from the tibial plafond. However, the number of diseases that involve the tibial cortex is great, and it can be difficult to arrive at a limited differential diagnosis from radiographic findings. OCD is suggested by a loss of the sharp cortical line of the articular surface. Osteochondral Lesions of the Talus: Aspects of Current Management. The medial central tibial plafond was most frequently involved site with 8 of the 38 (21%) lesions located there; the posterior medial tibial plafond was second most frequently involved with six of the 38 lesions (16%). Always check ankle X-rays for a talar dome OCD. It is often used synonymously with osteochondral injury/defect and in the pediatric population. On conventional radiographs, osteochondral lesions can appear as lucencies in the articular epiphysis. Apparent irregularity (arrow) along lateral fibular metaphysis on frontal view (a) has well-corticated margins (arrowheads) on oblique view (b). (2018) Radiographics : a review publication of the Radiological Society of North America, Inc. 38 (5): 1478-1495. There may be slight spreading of either half of the epiphysis away from the cleft. Fig. Literature data do not report clinical records with significant number of cases and follow-up. The Foot and Ankle Outcome Score (FAOS) and Short Form-12 (SF-12) general health questionnaire were used to obtain patient-reported functional outcome scores preoperatively and postoperatively. The recognized sites of osteochondral defects are: Osteochondral injuries are graded according to the stability and location of the fragment and presence of secondary degenerative changes (see: osteochondral injury staging). 3.

This term covers a wide spectrum of pathologies including (sub)chondral contusion, osteochondritis dissecans, osteochondral fracture and osteoarthritis resulting from longstanding disease. Six of 38 ankles had both a talar osteochondral lesion and an OLTP. Sanders TG, Paruchuri NB, Zlatkin MB. ... than in the tibial plafond (see the last 4 images below) and is 4-14 times more common. Osteochondral lesions of the distal tibial plafond: localization and morphologic characteristics with an anatomical grid. However, they are insensitive to grading lower stage lesions and are inadequate in predicting stability. 3. (1999) Foot & ankle international. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management. Elias I, Raikin SM, Schweitzer ME, Besser MP, Morrison WB, Zoga AC. Additional investigation (CT/MRI): [Picture 2] CT revealed an osteochondral lesion of the distal tibia. 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.Â, Osteochondral defect is a broad term that describes the morphological change of a localized gap in the articular cartilage and subchondral bone 5. At earlier stages (stage 1 to 4), a number of options exist including: The knee is a complex synovial joint that can be affected by a range of pathologies: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Additional MRI findings were scored as present or absent: focal chondral thinning or absence at the notch of Harty, focal subcortical osteosclerosis at the anteromedial margin of the tibial plafond, osteochondral lesions elsewhere in the ankle, subchondral edema signal or cystic change at the tibial plafond, and the presence of an ankle joint effusion. 2001;219 (1): 35-43. In my experience these lesions have a good healing potential without developing a loose body. CONCLUSION: Osteochondritis dissecans of the tibial plafond is a rare condition that may not be detectable on radiography. 2.

Clinical and MRI Outcomes After Arthroscopic Microfracture of Osteochondral Lesions of the Distal Tibial Plafond. MRI is the modality of choice, with high sensitivity and specificity for the detection of separation of the osteochondral fragment (see: osteochondral injury staging and osteochondritis dissecans surgical staging). Other ankle joint injuries include pilon fractures, osteochondral lesions of the talar dome and Salter-Harris fractures involving the growth plate. Abstract Lesions that involve the cortex of the tibia are fairly common in radiology practice. Osteochondral lesions or osteochondritis dessicans can occur in any joint, but are most common in the knee and ankle. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. fractures involving a single facial buttress, Meyers and McKeevers classification (anterior cruciate ligament avulsion fracture), Watson-Jones classification (tibial tuberosity avulsion fracture), Nunley-Vertullo classification (Lisfranc injury), pelvis and lower limb fractures by region. Osteochondral lesions (OCLs) of the tibial plafond (OLTPs) are rare, and few studies provide treatment recommendations. 22 (4): 765-74.

The objective of this study was to assess functional and magnetic resonance imaging (MRI) outcomes following microfracture for tibial osteochondral lesions. 2006;187 (5): 1332-7. The aim of this study was to evaluate the incidence and morphologic characteristics of osteochondral lesions of the distal tibial plafond (OLTP) by location and morphologic characteristics on MRI. In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. Pilon fractures involve the tibial plafond. The objective of this study was to assess functional and magnetic resonance imaging (MRI) outcomes following microfracture for tibial osteochondral lesions. 5. • Key MR imaging: • following anterior cruciate ligament repair), femoral condyle (most common in the lateral aspect of the medial femoral condyle), the signal is variable with intermediate to low signal adjacent to fragment and variable fragment signal, low signal loose bodies, outlined by high signal fluid, donor defect filled with high signal fluid. Osteochondral lesions of the distal tibial plafond (OLTPs) are an uncommon problem. Both x-rays and CT are able to detect displaced defects with ease. In distal tibia the cleft tends to prefer the medial plafond at its connection with the medial malleolus.
