11, Arthroscopy: The Journal of Arthroscopic & Related Surgery, Vol. The accuracy of the drilling path with respect to the articular cartilage was measured with an electronic digital caliper. Drilling was performed as close as possible to the cartilage without perforation. The authors performed and assessed a magnetic resonance (MR)-assisted navigation method for minimally invasive retrograde drilling of talar osteochondral lesions. However, dorsomedial talar dome lesions are frequently inaccessible with antegrade drilling techniques (13). We used a cutter with an internal diameter of 4.5 mm. However, this does not nullify our results since in vivo osteochondral lesions are often larger than 4.5 mm in diameter (22). The artificial osteochondral lesion (aiming point) and lateral process of the talus (insertion point) must be visible.

Initially, T1-weighted gradient-recalled echo and T1-, T2-, and intermediate-weighted fast spin-echo (SE) sequences (Table) were assessed with respect to their potential for use in drilling with MR guidance (hereafter, MR-guided drilling) in an open 1.0-T MR imager (Panorama HFO; Philips Healthcare) with a 21-cm-diameter surface coil. Fluoroscopic imaging is a two-dimensional imaging modality; thus, switching between planes is required, resulting in a longer more arduous drilling procedure, with higher cumulative radiation exposure to the surgeon and patient (15). (1). The time needed for planning the coronal drilling plane on the user interface, drilling guide alignment, and interactive drilling was assessed by a medical technical assistant for all 12 drillings. A 3-mm-diameter cancellous bone cylinder was extracted from the calcaneus with a 3.5-mm-diameter titanium fraise (Invivo). The line on the MR image shows the planned drilling direction. This study was partially supported by Philips Healthcare (Eindhoven, the Netherlands), Seiferth & Korneli (Zeulenroda-Triebes, Germany), and Invivo (Schwerin, Germany) in the form of scientific support and technical equipment.

The MR images were also shown on the monitor inside the operating room and provided the surgeon (C.J.S.) If these films demonstrate an osteochondral lesion of the talus, staging of the lesion should be performed. Dr Bevilacqua also reviews imaging modalities as well as surgical options available to treat depending on the size. This term covers a wide spectrum of pathologies including (sub)chondral contusion, osteochondritis dissecans, osteochondral fracture and osteoarthritis resulting from longstanding disease. A postoperative diagnostic MR examination (T1-, T2, and intermediate-weighted fast SE sequences) was performed to verify positioning. 6, CardioVascular and Interventional Radiology, Vol. 6, © 2020 Radiological Society of North America, Impact of high field (3.0 T) magnetic resonance imaging on diagnosis of osteochondral defects in the ankle joint, Osteochondritis dissecans: history, pathophysiology and current treatment concepts, Characterizing osteochondral lesions by magnetic resonance imaging, Arthroscopic therapy of steochondrosis dissecans of the talus: follow-up with a new “ankle score” [in German]. 11, No. OLT size showed significant correlation with postoperative MRI scores (MOCART 1: P = 0.006; MOCART 2.0: P = 0.004). Although confusion remains between the terms osteochondral injury and osteochondritis dissecans, it is really the etiology of the process that is in question. We drilled 16 holes in four ankle joints toward the talar dome. Diagnosis of Knee Osteochondral Lesions With Ultrasound Imaging Arthrosc Tech. After drilling, the guide was held in position, and a 3.5-mm titanium fraise was inserted without problems into the drilling canal. Elbow involvement in osteochondritis dissecans is rare.It is defined as a localized fragmentation of bone overlying the capitellum cartilage. When planning the treatment of osteochondral lesions of the talus, it is important to evaluate the articular cartilage to distinguish between stable and unstable lesions (1,2). The cadaver models were obtained by amputating the lower third of the lower leg: Eight specimens were obtained from the left ankle, and eight were obtained from the right. The third step was to adjust the direction of the drilling guide so that the cylinder-shaped marker, access point of drilling, osteochondral lesion, and tubule marker were aligned (Fig 3). Complete detachment of osteochondral lesion. ; clinical studies, C.J.S., T.J.; experimental studies, C.J.S., H.J.B., F.W., T.J., I.S.P., J.C.R., R.S., A.W., S.S.C., U.K.M.T.

MR imaging is an accurate method with which to evaluate osteochondral lesions of the ankle joint, and it has become a widespread imaging modality with which to diagnose ankle disorders (1,3,5,16,17). After modeling an ankle fixation cast and performing computed tomography (CT) of the ankle, the first step was to plan drilling with an optical navigation system. Materials and methods: Eight patients (seven male patients, one female patient; age range, 15-42 years; mean age, 27 years) with an OCD in the glenoid fossa were identified. Elbow involvement in osteochondritis dissecans is rare.It is defined as a localized fragmentation of bone overlying the capitellum cartilage. The ankle joints were positioned and fixed so that the lateral ankle was at the top, simulating a lateral patient position. Drilling was performed with near-real-time MR guidance. Skeletal Differentiability of anatomic structures is best in d.

Although confusion remains between the terms osteochondral injury and osteochondritis dissecans, it is really the etiology of the process that is in question. The MR-assisted retrograde drilling of osteochondral lesions may lead to precise and secure treatment without radiation exposure. The smallest artifact of the 3.4-mm titanium spiral drill bit can be seen in d. Bottom: Coronal images of the ankle obtained during interactive drilling. The high incidence of good outcome in our series indicates that the one-step BMDCT could be a valid option for the treatment of this rare type of lesions. Osteochondral Lesions … The locking bolts (B) can be seen. The smallest artifact of the 3.4-mm titanium spiral drill bit can be seen in d. Bottom: Coronal images of the ankle obtained during interactive drilling. The articular cartilage imaging group of the International Cartilage Repair Society has issued detailed recommendations with r… In c, the artificial osteochondral lesion (*) was hit, but the remaining cartilage remained intact. Arthroscopic drilling is an effective and minimally invasive treatment. 18 May 2017 | Scientific Reports, Vol. Fluid extended deep to the fragment, and there was subjacent marrow edema, all seen in Fig. Aurich, M, Bedi, HS, Smith, PJ, Rolauffs, B, Muckley, T, Clayton, J. Haene, R, Qamirani, E, Story, RA, Pinsker, E, Daniels, TR. J Bone Joint Surg Am. In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. The authors retained full control of all data collected and information submitted for publication. Commonly, this is achieved by drilling the subchondral bone (6 – 12). Use of this interactive MR-assisted navigation method in combination with a passive aiming device allowed precise and rapid retrograde drilling of talar osteochondral lesions. This enables a merger of the diagnostic and therapeutic processes. After we drilled the talus (as described previously), the cancellous bone cylinder was brought into the drilling canal with MR guidance. the site you are agreeing to our use of cookies. Both magnetic resonance (MR) imaging and ankle arthroscopy are excellent tools commonly used to evaluate ankle cartilage (3–5). When an osteochondral lesion of the talus is included in the differential diagnosis, radiographic examination should include weight-bearing anteroposterior, lateral, and mortise views of the ankle joint 10. The markers of this drilling guide were oriented so that both markers were visible in the defined coronal image plane of the ankle joint (Fig 2). In c, the artificial osteochondral lesion (*) was hit, but the remaining cartilage remained intact. In c, the artificial osteochondral lesion (*) was hit, but the remaining cartilage remained intact. Osteochondral lesions (osteochondritis dissecans) of the talus are common articular lesions that are usually traumatic in origin. After the drilling capsule and marker tubules are placed and adjusted, they can be moved back and forth to accommodate the anatomic region and dimensions before being locked in place with the synthetic screws. In the third, no change occurred in the size or appear-ance of the lesion over 4 years (Fig. 4.11a–c. Furthermore, many lesions are located in the posterior part of the talar dome. “Osteo” means bone and “chondral” refers to cartilage. If the address matches an existing account you will receive an email with instructions to reset your password. CONCLUSIONS: Osteochondral lesions of the distal tibia represent a challenge for the orthopedic surgeon because of their difficulty diagnostic and rarities. Furthermore, the ankle joints of five volunteers without osteochondral lesions of the medial talar dome and one volunteer with an osteochondral lesion of the medial talar dome were imaged. Wiewiorski, M, Leumann, A, Buettner, O, Pagenstert, G, Horisberger, M, Valderrabano, V. Wiewiorski, M, Werner, L, Paul, J, Anderson, AE, Barg, A, Valderrabano, V. Kubosch, EJ, Erdle, B, Izadpanah, K, Kubosch, D, Uhl, M, Sudkamp, NP. The interactive intermediate-weighted fast SE pulse sequence (repetition time msec/echo time msec, 400/8; 3-mm section thickness; 200 × 138 field of view) was shown to be superior in the initial sequence evaluation. An osteochondral injury involves the separation of a segment of articular cartilage along with its underlying bone. Many of these lesions are first diagnosed by plain film. The first step of this procedure was to define the coronal plane in which drilling was planned by using the interactive modus on the user interface outside the operating room. As the drill can be fully seen in one imaging plane during the drilling procedure, a second plane is not usually required. Prognosis of these lesions depends on stability, location, and size of the lesion.Imaging has an essential role in the diagnosis, staging, and management of osteochondral lesions. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). With the transmalleolar antegrade drilling technique, the malleolar joint cartilage is also damaged (13). Foot Ankle Int 1999; 20:474-480. 4–5 In a … Bonnel, F, Toullec, E, Mabit, C, Tourné, Y, Sofcot. Note.—The interactive intermediate-weighted fast SE sequence was proven to be the best.
