Characterizing osteochondral lesions by magnetic resonance imaging. Subchondral bone cysts commonly occur adjacent to a treated focal cartilage defect and are possibly connected to the joint cavity. 1986; 68(6): 862–5. [6, 20]. Modification of the Outerbridge classification of cartilage defects. 11. The fracture can be seen as irregular linear or curvilinear subchondral low signal intensity structure near the subchondral bone plate of low signal intensity in T1-weighted  images and also sometimes, but not always in T2-weighted images 1,2,4-8. The weight-bearing joints such as the knee, hip, and ankle joints are more commonly affected ref. There are two generally accepted theories on the etiology of subchondral cysts. Osteochondral lesions (OCL) of the talus involve both articular cartilage and subchondral bone of the talar dome. Subchondral fractures are usually a consequence of compressive forces, transmitted from the cartilage to the subchondral bone plate and from there to the trabeculae, which fail to resist that force and break or fracture 3. Schematic drawings of OCL classification according to Anderson. Staging of Osteochondral Lesions of the Talus: MRI and Cone Beam CT. Journal of the Belgian Society of Radiology. A mnemonic for the causes of subchondral cysts is: COORS Mnemonic C: CPPD O: osteoarthritis O: osteonecrosis R: rheumatoid arthritis S: synovial-based tumors See also Geode A subchondral cyst without superficial cartilage damage is rare and requires a different approach. 195 (1): W63-8. The first system of classification has been reported by Berndt and Harty in 1959 [4], including four stages based on their radiological appearance. When the latter is present, then joint replacement is often the only feasible treatment. Jose J, Pasquotti G, Smith MK, et al. 2016; 2016: 3594253. (2019) Skeletal radiology. Yamamoto T, Iwasaki K, Iwamoto Y. Transtrochanteric rotational osteotomy for a subchondral insufficiency fracture of the femoral head in young adults. The accuracy also depends of the strength of the field and is lower on 1.5 Tesla magnets in comparison to 3T [11]. These cysts are produced in areas of damaged articular cartilage, subjacent to the underlying subarticular cortical plate. This is not Kienbock's disease, where cystic changes develop more diffusely.

Osteochondral Lesions of the Knee: Differentiating the Most Common Entities at MRI. Fluid-fluid levels, consistent with secondary formation of aneurysmal bone cysts, are seen in 14% of cases. Schematic drawing of talocrural joint injury in pronation (a) results in sprain of the medial collateral ligaments (brown) and lateral-sided OCL of the talar dome and/or kissing tibial lesion (orange zones), whereas injury in supination (b) causes sprain of the lateral ligaments and medial-sided OCL of the talar dome and/or kissing lesions at the tibia (orange zones). The articular cartilage layer of the talocrural joint is indicated in blue. This term covers a wide spectrum of pathologies including (sub)chondral contusion, osteochondritis dissecans, osteochondral fracture and osteoarthritis resulting from longstanding disease. Arthroscopic treatment of chronic osteochondral lesions of the talus: Long-term results. Subchondral cystic lesions are common features that are associated with many arthropathies and synovial-based processes. DOI: https://doi.org/10.1148/radiol.2333031921, Kirschke, JS, Braun, S, Baum, T, Holwein, C, Schaeffeler, C, Imhoff, AB, et al. With widespread use of MR it is now not uncommon in clinical practice to observe this progression of findings. Therefore, for more accurate evaluation of cartilage covering of articular surfaces of the talar dome and distal tibia and fibula, direct arthrographic techniques combined with CT and MRI may be useful (Figure 2d). In adult patients, the depth of the cartilage lesions is often understaged (Figures 3 and 4). Direct comparison of conventional radiography and cone-beam CT in small bone and joint trauma. DOI: https://doi.org/10.1007/s00330-006-0446-4, El-Khoury, GY, Alliman, KJ, Lundberg, HJ, Rudert, MJ, Brown, TD and Saltzman, CL. 4 (3): 173-80. AJR Am J Roentgenol 1977;128:799–806. CBCT, which was first introduced for preoperative evaluation of dental implants, is currently also used for musculoskeletal applications. Diagnostic value of CT arthrography for evaluation of osteochondral lesions at the ankle. Studies on cadavers performed on CT arthrography [12] showed more accurate cartilage thickness measurements in comparison to standard MRI, which is in line with a superior evaluation of OCL with CT arthrographic techniques [13] (Figure 9). Nowadays MR staging of OCL on MRI is usually done by the Anderson classification [9], which is another modification of the initial staging system based on plain film evaluation by Berndt and Harty (Figure 6). 9. It uses a conical X-ray beam and flat-panel detector collecting all volumetric data in one rotation of the gantry. Stage 3 according to Anderson classification. “Staging of Osteochondral Lesions of the Talus: MRI and Cone Beam CT”. The equipment is designed to perform exams in sitting or supine position and is relatively compact, allowing installation in many radiology departments and private practices. 2007; 17(6): 1518–28. Finally, when fluid flows underneath the defect, the OCD can become unstable and may result in a corpus liberum. This review aims to summarize the available evidence on the evaluation and treatment of scaphoid cystic lesions to help guide clinical management. Sclerotic lines as a result of impaction or as slight deformities of the joint line in case of subchondral collapse can sometimes be seen particularly at a later stage 4. When a small defect in the chondral plate is present, the intraarticular fluid will erode the subchondral bone, which will result in bone marrow edema. Subchondral cysts of the tibia secondary to osteoarthritis of … Subchondral bone involvement can be manifested by bone marrow edema (BME), fracture, sclerosis and/or cyst formation. ... extends to the subchondral bone, and occurs in patients with closed physes (4 ... Skeletal Radiology, Vol. Additional CBCT-Arthrography is, however, very useful for more accurate cartilage staging and should be considered in those clinical scenarios where arthroscopic treatment of the lesion is considered. (2015) Acta radiologica (Stockholm, Sweden : 1987). Subchondral means under the cartilage and refers to fluid filled cavities within the bone that is under the cartilage. The etiology of subchondral cysts is unknown. Staging of Osteochondral Lesions of the Talus: MRI and Cone Beam CT. Journal of the Belgian Society of Radiology, 101(S2), p.1. 1. Coronal reformatted CBCT-A (c) barely shows subtle subchondral sclerosis at the superolateral aspect of the talar dome and intact overlying cartilage. Although Magnetic Resonance Imaging (MRI) at 1.5 Tesla is the leading cross-sectional modality for detection and staging of OCL, lack of spatial resolution hampers accurate assessment of thin articular cartilage. The presence of a subchondral edema with an acetabular cyst on MRI is indicative of a full-thickness cartilage lesion at the time of arthroscopy. The articular surface of the talus is large and its blood supply is critical in the watershed areas [1] explaining an impaired healing process and predisposition to posttraumatic necrosis in those vulnerable areas. Am J Sports Med. Usually, subchondral fractures present as linear or curvilinear structures often paralleling the subchondral bone plate, with or without areas of subchondral collapse 2. The sac is usually primarily filled with hyaluronic acid. Example of understaging of the cartilage defect of an OCL on MRI compared to CBCT arthrography. Note the more subtle subchondral cyst formation in the proximal margin of the hamate (H), related to chronic repetitive abutment with the lunate (type II lunate morphology with an extra facet which articulates with the hamate). 2008; 16(11): 1047–51. This article highlights some of the causes and treatment options for Subchondral Bone Cysts. Hallmarks of osteoarthritis include the presence of marginal osteophytes and subchondral cysts in the tibiofemoral joint. For staging of OCL of the talus several grading systems have been proposed. Recently, Cone Beam Computed Tomography (CBCT) of small joints has been introduced as an alternative technique for Multi Detector CT, combining a very high spatial resolution, low radiation dose and low cost [3]. MRI is an excellent imaging tool, able to detect osteoarthritis indicators such as chondromalacia (with a magnet strength of 1.5 T, it has a sensitivity of 100% for grade III and IV lesions) 20, 21, subchondral edema, and subchondral cysts … J Bone Joint Surg Br 1955;37:663. Compared to the articular cartilage of the knee, cartilage of the ankle joint is very thin and the spatial resolution of MRI may be insufficient for detection of small lesions. Coronal (a) and sagittal (b) fat suppressed T2-WI show adjacent kissing areas of bone marrow edema (white arrowheads) at the distal tibia and talar dome. Subchondral cysts in the superior outer and middle third of the femoral head (pressure zone) may arise from bone contusion and synovial intrusion or osteoclastic resorption of necrotic trabeculae following avascular necrosis 1. It's a fluid-filled sac that forms in one or both of the bones that make up a joint. The index cases demonstrate a subchondral fracture, which progresses to osteonecrosis and cortical collapse. 7. More severe symptoms tend to occur in the radiographically more advan… The symptoms you will likely notice are: Lameness may be acute or hardly noticed unless the horse is working at specific increased speeds or when involved in specific activities - intermittent, especially in older horses but can be noted in horses of any age Due to its noninvasiveness, absence of radiation exposure and its ability to visualize associated concomitant soft tissue abnormalities, MRI is the initial technique for exclusion/confirmation of an osteochondral lesion of the ankle. Coronal fat suppressed T2-WI (intermediate weighting) showing BME (white asterisk) at the lateral corner of the talar dome (a). In this regard, CBCT-Arthrography (CBCT-A) may be very promising technique for precise staging of cartilage lesions of the ankle as an alternative for Multi Detector Computed Tomography (MDCT). American journal of roentgenology. The purpose of this pictorial review is to illustrate the strength of each imaging method. Despite the combination of these MR parameters, accurate cartilage evaluation remains often illusive.

A comparison of arthroscopic and MRI findings in staging of osteochondral lesions of the talus. Disqus. Osteonecrosis can develop when the lesion’s vascularity is disrupted. in 2003. As a result, the diagnosis of “spontaneous osteonecrosis of the knee” has been abandoned and is now recognized as osteonecrosis developing following a subchondral fracture (see Web clinic February 2004). In osteoarthritis, the overloading and the vascular obstruction within the subchondral bone leads to subchondral sclerosis, bone marrow edema and bleeding, and subchondral cysts. DOI: http://doi.org/10.5334/jbr-btr.1377, Posadzy, M., Desimpel, J., & Vanhoenacker, F. M. (2017). Note also partial filling of the subchondral cyst (black arrowhead) with contrast as an indirect sign of joint communication through a cartilage lesion. Sometimes visible as subchondral hyperlucency with a decrease in bone density. (2016) Radiology. J Bone Joint Surg Am. Anatomy of the talocrural joint.

The synovial fluid intrusion theory suggests that elevated intra-articular pressure forces joint fluid into the subchondral bone via fissured or ulcerated cartilage,, creating a cyst. They can also occur in conjunction with twisting and ligamentous injuries. DOI: https://doi.org/10.1155/2016/3594253, Posadzy, M., Desimpel, J. and Vanhoenacker, F.M., 2017. In stage 3 an undisplaced completely separated fragment can be seen on MRI with adjacent BME. The overlying cartilage is difficult to assess on MRI but seems to be slightly inhomogeneous (white arrow). 101, no. Useful MR scoring parameters include lesion location, lesion size in 3 planes, subchondral bone marrow edema, subchondral cyst formation and/or sclerosis, status of the overlying cartilage, contour depression of the articular bone plate. Sagittal (a) fat suppressed T2-WI show a subchondral band-like area of low signal at the subchondral cortex (white arrow) with surrounding BME (white asterisk). subchondral bone marrow edema on dual-energy CT; MRI. Cone Beam Computed Tomography (CBCT) arthrography is better suited for precise staging of cartilage lesions. They can progress to subchondral collapse, osteochondral injury, and osteochondral defects 1. Acute and Stress-related Injuries of Bone and Cartilage: Pertinent Anatomy, Basic Biomechanics, and Imaging Perspective. Subchondral bone involvement can be manifested by bone marrow edema (BME), fracture, sclerosis and/or cyst formation. The pathologic definition of a cyst is a cavitary, fluid-filled lesion with an epitheli-al lining [21]. {"url":"/signup-modal-props.json?lang=us\u0026email="}. In our patients, from the follow-up X-ray and MRI we observed a satisfied regeneration of the subchondral bone without bone resorption or recurrence of the cyst, indicating that cancellous bone autograft is an effective method for treating subchondral cysts.Furthermore, the successful reconstruction of the subchondral bone significantly relieved the patients' symptoms, as the … Accurate staging of cartilage lesions is of utmost importance, as this will have a major impact on the treatment strategy and ultimate prognosis. Stage 2 refers to partial detachment of OCL with subchondral cyst formation or fissure incompletely separating the lesion from the talar dome. Furthermore, cartilage lesions may be isolated (one defect), complex (one lesion with variable depth of the lesion) or multifocal (involving multiple areas of the talus or tibia). Biomed Res Int. Coronal PD fat suppressed coronal image (a) showing an OCL fragment completely detached from talar dome without displacement (arrow), bone marrow oedema (star) of adjacent part of the talus. Based on the combination of MRI and CBCT findings the diagnosis of a subchondral insufficiency fracture (SIF) was made. As the bulk of the U.S. population ages, the prevalence of osteoarthritis is expected to rise. Journal of the Belgian Society of Radiology, vol. [7], who correlated MR imaging with arthroscopic appearance. Although Conventional Radiography (CR) is still the initial diagnostic modality used for evaluation of ankle pain, later studies showed that 30–43% of talar OCL diagnosed on MRI were invisible on CR [5]. Subchondral cysts are typically found within the hip joint. The overlying cartilage is difficult to assess on MRI. Arthroscopic evaluation of the cartilage is regarded as the gold standard [2], but due to its invasiveness and the need for anesthesia, it should be reserved for preoperatively well-documented cases and combined with surgical treatment procedures. Foot Ankle Surg. 2015; 44(8): 1111–7. Stage 1 lesion according to Anderson classification. 1959; 41–A: 988–1020. Pathria MN, Chung CB, Resnick DL. Unable to process the form.

However, the sensitivity of conventional radiography in osteophyte depiction is limited compared with that of magnetic resonance (MR) imaging (4,5). Due to the widespread use of fluid-sensitive sequences on MRI, even subtle foci of BME may be seen adjacent to a cartilage defect, particularly in acute or subacute OCL lesions. Coronal (c) and sagittal (d) reformatted CBCT-A show a focal bony lesion with peripheral sclerosis in the distal tibia and talus. The exact pathogenesis of these degenerative cysts is not certain.26,27 Subchondral cysts are most often seen in association with osteoarthritis, but may occur as the result of degeneration or injury of the overlying articular cartilage by other causes. DOI: http://doi.org/10.5334/jbr-btr.1377, Posadzy, Magdalena, Julie Desimpel, and Filip M. Vanhoenacker. MRI is the most sensitive method to depict this stage without any correlating signs on CR or CBCT with injection of intraarticular contrast. Assess range of motion to evaluate for pain and limitation as well as clicking or catching of the joint. Cartilage damage may have a variable imaging appearance ranging from a small fissure, a distinct defect, flap formation or delamination. Lomax, A, Miller, RJ, Fogg, QA, Jane Madeley, N and Senthil Kumar, C. Quantitative assessment of the subchondral vascularity of the talar dome: A cadaveric study. In particular cases also alternative diagnoses can be made on basis of CBCT (Figure 11). The authors have no competing interests to declare. 468 (12): 3181-5.

On plain films, the subchondral bone is seen as a thin layer of compact bone with a smooth surface and a uniform adjacent trabecular bone (Figure 2b). THE IMPORTANCE OF THE DIAGNOSIS OF SUBCHONDRAL FRACTURE OF THE FEMORAL HEAD, HOW TO DIFFERENTIATE IT FROM AVASCULAR NECROSIS AND HOW TO TREAT IT. Osteochondral lesions (OCL) of the talus are defined as any damage involving both articular cartilage and subchondral bone of the talar dome. Stage 4 consists of a displaced fragment, often accompanied with surrounding bone marrow edema. 280 (1): 21-38. Subchondral insufficiency fracture of the knee: grading, risk factors, and outcome. The red arrow indicates the direction of the applied force. (2010) AJR. Subchondroplasty: What the Radiologist Needs to Know. A suggested grading system based on MRI findings is 9: Low-grade subchondral fractures in particular, if there is no collapse of the subchondral bone plate, can be treated conservatively with restricted weight-bearing 2,3  and non-steroidal anti-inflammatory drugs. DOI: https://doi.org/10.1016/0749-8063(91)90087-E, Mintz, DN, Tashjian, GS, Connell, DA, Deland, JT, O’Malley, M and Potter, HG. Because the plasticity of the cartilage in children and adolescents is higher than in adults, OCL lesions in young patients are often characterized by isolated subchondral bony changes without overlying cartilage disruption (Figure 5). 2. S2, 2017, p. 1. Their walls consist of a cell layer resembling synovium, and the surrounding wall is osteosclerotic. Besides the limitations of MRI in this field, it is still considered the most comprehensive imaging modality of the ankle because of its capability to assess soft tissue and bone marrow abnormalities on a single examination. With the advent of MRI, this grading system was further revised including evaluation of structures invisible on conventional radiology, such as the integrity of the cartilage and presence of BME. Ostlere SJ(1), Seeger LL, Eckardt JJ. Although the incidence of osteoarthritis increases with age, the condition is not a normal part of the aging process. MRI sensitivity in detection of OCL of the talus, correlated with arthroscopic correlation, varies according to different studies and has been reported as high as 81% [10]. Conventional radiographs are currently the standard for establishing a radiographic diagnosis of knee osteoarthritis (1–3). This is an i… Almost always there will be associated bone marrow edema best appreciated in fat-saturated T2-weighted and intermediate or proton-density weighted images 4. As MRI is inaccurate for the evaluation of the articular cartilage compartment, further staging with direct arthrographic techniques are often mandatory if an OCL is detected on MRI and in those scenarios in which arthrosopic treatment is considered. It has also been shown that both small (≤5 mm) and large (>5 mm) MR imaging–depicted osteophytes are associa… What Is a Subchondral Bone Cyst? S2 (2017): 1. (2009) Revista brasileira de ortopedia.

Case 2: subchondral insufficiency fracture, subchondral insufficiency fracture of the knee, directly visible subchondral trabecular discontinuity on high resolution, signs of subcortical impaction visible as subchondral hyperdensity, grade 2: bone marrow edema with low signal intensity fracture line, grade 3: fluid-filled fracture line and cysts, grade 4: cortical collapse with a step off, concave, smooth half-moon/crescentic appearing necrotic segment, usually in conjunction with chondral damage. Scaphoid intraosseous cystic lesions represent a rare subset of carpal bone cysts. Background: Cystic lesions of the carpal bones are rare entities that are infrequently reported in the literature. Subchondral cysts are often a part of the joint degenerative process and occurs where there are breaks in the hip joint cartilage. Coronal PD fat suppressed MRI image (b) revealing BME (star) in the posteromedial part of the talar dome. Subchondral lucency (SCL), also referred to as subchondral bone cysts, can cause clinical problems in horses and humans. On the other hand, although MRI a very useful and sensitive technique for evaluation of the subchondral compartment (showing either BME or cyst formation), the precise depth and extent of the overlying cartilage lesion is often not accurately staged. Roemer FW, Frobell R, Hunter DJ, et al. Skeletal Radiol. 2003; 19(4): 353–9. Osteoarthritis is one of the most prevalent and disabling chronic conditions affecting older adults and a significant public health problem among adults of working age.

Treatment depends on the location and size of the defect as well as the presence of secondary degenerative changes. However, other arthritic conditions like rheumatoid arthritis also play a key role in an individual developing Subchondral Bone Cysts. The cartilage at the talar dome is slightly irregularly delineated (white arrow). 207 (6): 1257-1262. In addition, the trabecular architecture of subchondral bone is far better visualized on CBCT than on CR. Symptoms of subchondral cystic lesions can be mild to severe and can be of an acute onset. In fact, Subchondral Bone Cyst is one of the parameters that physicians look at when diagnosing osteoarthritis. Knee Surg Sports Traumatol Arthrosc.
