ocd tibial plafond

The cause of Tibial Plafond Fracture is axial or rotational forces occurring from motor vehicle accidents or falling from a height. Perhaps in some individuals, the tibial plafond is less stiff than the talar dome, placing them at risk for osteochondritis dissecans of the tibial plafond. Short description: Osteochondritis dissecans, unsp ankle and joints of foot The 2021 edition of ICD-10-CM M93.279 became effective on October 1, 2020. Osteochondral defects ( OCD) or lesions ( OCL) are focal areas of damage with articular cartilage damage and injury of the adjacent subchondral bone … Ankle Platform is for Orthopedic Surgeons with special interest in Ankle and Hindfoot. Conclusion: Osteochondritis dissecans of the tibial plafond is a rare condition that may not be detectable on radiography. OCD: talus, tibial plafond, navicular Subtalar joint Calcaneonavicular coalition [anteater nose sign] Talocalcaneal coalition [complete C-sign] Anterior process of calcaneus Check base of fifth metatarsal for Jones fracture Medial aspect of 2nd metatarsal aligns with medial aspect of middle cuneiform Foot and ankle disorders 359 A less likely explanation is that some patients may undergo surgery without radiologic examination or that the radiographs were obtained in the orthopedist's office and were not available to the radiologists for review. 1A). Inversion and rotation of a plantar flexed foot causes compression of the posterior half of the talar dome by the posterior malleolus, resulting in osteochondritis dissecans [8]. steochondral lesions of the distal tibial plafond are rare—far less common than osteochondral lesions of the talus1-4. Members receive the 'Picture of the week', new operative techniques and can submit their problem cases for an expert opinion. Under experimental conditions, Berndt and Harty [8] produced osteochondritis dissecans in the middle or anterior half of the talar dome with strong inversion of the dorsiflexed ankle. The search was limited to English literature and human subjects. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management.. stage I. injury limited to articular cartilage; MRI findings: subchondral edema; x-ray findings: none; stage II. The tibial plafond cartilage was intact without any visible defect or flap. High-Resolution 3-T MRI of the Fingers: Review of Anatomy and Common Tendon and Ligament Injuries, Original Research. Open ankle fracture with exposed tibial plafond. The debrided lesion is located arthroscopically with the ball tip of a microvector guide. 3C). Athanasiou et al. Most osteochondritis dissecans in the ankle is found in the talar dome. However, a case of mirror image osteochondral defects of the talus and distal tibia suggests trauma as a potential cause of this lesion [4]. The prevalence of osteochondritis dissecans in the tibial plafond detected on radiography is unknown. This includes initial rest, immobilization, and unloading protocol, in either a fracture boot or cast. An Osteochondral Lesion of the Distal Tibia and Fibula in Patients With an Osteochondral Lesion of the Talus on MRI: Prevalence, Location, and Concomitant Ligament and Tendon Injuries. Five months after arthroscopy and débridement, the patient continued to have medial ankle pain, but the severity of the pain decreased. Osteochondritis dissecans (OCD) is a localized injury or condition affecting an articular surface that involves separation of a segment of cartilage and subchondral bone (Schenck, 1996). Our literature search yielded three articles on osteochondritis dissecans of the ankle, which included cases of osteochondral lesions of the tibial plafond [4,5,6]. It is also known as Pilon fracture and explosion fracture. Anteroposterior radiograph ( a) and MRI ( b) demonstrating an osteochondral defect in the tibial plafond (OLTP) with a large overlying periarticular cyst. The opinions and assertions contained herein are those of the authors and should not be construed as official or as representing the opinions of the Department of the Army or the Department of Defense. cartilage injury with associated subchondral fracture but without detachment We noted no predominant location of the osteochondritis dissecans. All patients underwent radiography, one patient underwent CT, and one patient underwent MR imaging. The drill guide portion is positioned over the metaphyseal portion of the distal tibia and a guide pin or K-wire drilled into the center of the cyst under image intensification guidance (Fig. In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. Table 1 summarizes the findings in our three patients and the cases in the literature. In our series, the average size of the osteochondral lesions was 1.4 × 1.3 cm. Six of 38 ankles had both a talar osteochondral lesion … Talar dome lesions are usually caused by … The softest cartilage was found in the posterior half of the talus. The cartilage in the anterolateral aspect of the distal tibia was stiffer and thicker than that in the anterolateral aspect of the talus. Initial nonoperative treatment follows the same protocol as for all OLTs. Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone.

Typical HCPCS Codes • C1762 – Billing code for allograft . • 29892 – Arthroscopically aided repair of large OCD lesions, talar dome fracture or tibial plafond fracture, with or without internal fixation • 29999 – Unlisted procedure, arthroscopy. CT and MR imaging are able to show the exact location and extent of the lesion. We report the imaging characteristics of osteochondritis dissecans of the tibial articular surface (tibial plafond). 72 plays. ... OCD is seen as a complication of approximately 6.5% of ankle sprains. Three of the patients described in the literature underwent surgery, curettage of subchondral cyst with bone graft [4] or débridement of the damaged articular surface followed by a period of non—weight-bearing on crutches for 6 weeks [5]. Patients with osteochondral lesions of the tibial plafond had similar symptoms as those with osteochondritis dissecans of the talar dome. Copyright © 2013-2020, American Roentgen Ray Society, ARRS, All Rights Reserved. No complication was reported at a 20-year follow-up examination [5]. In the radiology literature, we are aware of only one textbook describing this entity, without a specific reference [2]. Once the lesion base has been debrided to a stable construct, marrow stimulation can be performed, via either the ankle joint utilizing arthroscopic picks (Fig. OCD can occur in any diarthrodial joint, including the following in decreasing order of frequency: Elbow (capitellum) Ankle (talar dome or tibial plafond) Tarsal navicular; Hip (femoral capital epiphysis) Shoulder (humeral head or glenoid) Wrist (scaphoid) System(s) affected: musculoskeletal Imaging Characteristics and a Review of the Literature, Osteochondritis Dissecans of the Tibial Plafond, Review. Resources. In a patient with OCD of the knee, the affected leg may be externally rotated during gait in an attempt to avoid impingement of the tibial spine on the lateral aspect of the condyle. 0.0 (0) See More See Less. In the ankle joint, helical CT has the advantage of multiplanar capability. In my experience these lesions have a good healing potential without developing a loose body. On lateral images, osteochondritis dissecans is less apparent. The MRI is not however very accurate in determining the true size and depth of the lesion, nor the presence of subtle associated subchondral cysts, which are all better evaluated on CT scans (Fig. The purpose of this study was to evaluate the clinical outcomes and the level of sports activity following arthroscopic microfracture for osteochondral lesions of the tibial plafond. Although the biomechanic topography of human ankle cartilage explained the occurrence of osteochondritis dissecans in the talus, it did not explain the cause for an osteochondral lesion in the distal tibia. Bauer et al. In one patient, markedly hyperemic proliferative synovial tissue involved the entire ankle. Also, in one of the patients who had ankle arthroscopy, the talar dome was irregular, suggesting traumatic contact between the talus and the tibial plafond. All three patients were men. Radiologists may not be aware of this entity and may not recognize the lesion on conventional radiographs. The plafond is concave in the anteroposterior plane and convex in the lateral plane. Osteochondral injury of the tibial plafond is not as rare as previously reported in the radiologic literature. In general, tibial cartilage was stiffer than talar cartilage. 1C). Treatment for this may be different then in the early stages of the OCD lesion. Osteochondritis dissecans of the tibial plafond is a rare condition that may not be detectable on radiography. Methods: A retrospective review was conducted for patients who underwent arthroscopic microfracture surgery for osteochondral lesions of the tibial plafond from January 2014 to June 2017. The prevalence of osteochondritis dissecans in the tibial plafond detected on radiography is unknown. The cartilage can be torn, crushed or damaged and, in … The dome of the talus lies in the mortise created by the tibial plafond, distal fibula, and malleoli, and serves as a weight-bearing surface for the entire body. CONCLUSIONS: Clinical and radiological evidence of anterolateral impingement syndrome often accompanies stage 4 OCDs. However, coronal and sagittal images clearly show that the lesion originates from the tibial plafond. The appropriate treatment for osteochondral injury of the tibial plafond is unclear. Introduction: Osteochondral lesions of the tibial plafond account for approximately 2.6% of osteochondral lesions in the ankle. Consequently, radiologists must be aware of this entity and its imaging characteristics on different imaging techniques. Very interesting case of a typical Osteochondritis Dissecans in the posterior tibial plafond. Patients with OCD in the knee may have quadriceps weakness, not gluteus maximus weakness; however, this does not lead to a lack of patellar tracking. All lesions were centrally located, superior to the talus, without a predominant site. Diagnosis is usually made on a CT scan or magnetic resonance imaging (MRI) [ 2, 6 ]. I suggest you review the next query regarding Tibial Plafond fractures. In our series, two of three osteochondral lesions of the tibial plafond were detected on radiography. The second most common localization of the osteochondral defect in the OCD with loose bodies group was the medial plafond of distal tibia [in 9 of 29 (31.1%) patients]. Utilizing standard anteromedial and anterolateral portals, a diagnostic evaluation should be performed as described by Ferkel to evaluate for associated pathologies [, Arthroscopic view of OLTP in the central plafond, OLTP post debridement of unstable cartilage. The duration of nonoperative treatment is not well defined and should include input from the patient. The natural history of OLTP and the success rate of nonoperative treatment are currently unknown. Five patients were diagnosed with osteochondral injury of the tibial plafond. It is wider in the anterior plane to provide stability, especially while weight-bearing. Diagnosis is usually made on a CT scan or magnetic resonance imaging (MRI) [, Sagittal T2 and T2 MRI images demonstrating a posterior OLTP with active bone marrow edema. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. Apart from the location, osteochondral injury of the tibial plafond has radiographic findings similar to those of osteochondritis dissecans of the talar dome. A 1995 study [9] of the biomechanic topography of human ankle cartilage supports the experimental study of Berndt and Harty [8]. On MR imaging, osteochondral defect of the tibial plafond has low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, with adjacent bone marrow edema (Figs. On axial scans, osteochondral lesions of the tibial plafond may be initially mistaken for osteochondritis dissecans of the talar dome (Fig. The average age was 39 years (age range, 33-49 years). Bone grafting is usually performed in an antegrade manner. If non-surgical approaches fail to relieve the symptoms of an OCD, surgery may be necessary. The patients were referred to our department of radiology, and their conditions were diagnosed with various imaging techniques within a 2-week period. The cause of osteochondral injury in the tibial plafond is unknown. When Tibial Plateau Fractures Are A Pain The tibial plateau is an important weight -bearing part of the body that connects the thighbone (femur) to the shinbone via ligaments. CONCLUSION.
