The dates of the pre-operative MRI and surgery were recorded. Four surgical patients and one control patient were excluded from this part of the analysis as their MRI studies did not include the peroneus brevis muscle belly in the field of view. One hundred and five consecutive patients who had undergone peroneal tendon surgery between January 1, 2004, and December 31, 2019, were identified from a surgical database. 5, Trauma und Berufskrankheit, Vol. Dr. Charles Gordonanswered Specializes in Adolescent Medicine Talk now The interobserver reliability for the cleft sign was moderate for peroneus brevis (0.57) and substantial for peroneus longus (0.68). Marlena Jbara, MD discusses the identification of possible pathologies associated with the tendons, ligaments, and nerves around the ankle on MRI. Radiologists should recognize the normal anatomy and specific pathologic conditions of the peroneal tendons at US and MR imaging and understand the various treatment options for peroneal tendon and SPR injuries. [20-22] Split tears of the peroneus brevis tendon have been described as two distinct bundles as well as a C or boomerang-shaped tendon surrounding the peroneus longus tendon with central thinning. Peroneus Longus (Blue arrow) is normal. Within the rotator cuff, the degree of fatty atrophy significantly correlates with tear size and chronicity, with the highest degrees of fatty atrophy present in chronic massive full-thickness rotator cuff tears. .switcher a {text-decoration:none;display:block;font-size:10pt;-webkit-box-sizing:content-box;-moz-box-sizing:content-box;box-sizing:content-box;} Additional findings included fluid in the tendon sheath (n = 6), marrow edema of the lateral calcaneal wall (n = 3), enlarged peroneal tubercle (n = 3), and tear of the peroneus brevis tendon (n = 2).

Chief Medical Officer, ProScan Imaging. The MRI examinations of the surgical and control subjects were randomized and independently reviewed by two musculoskeletal fellows who were blinded to the original MRI and operative reports. For example, tendons with partial thickness tears can be thickened or thinned with intermediate or high, linear, or globular T2 signals. We aimed to compare the diagnostic performance of an objective set of magnetic resonance imaging (MRI) criteria named the cleft sign with traditional reads for pre-operative diagnosis of peroneal tendon tears. Careers. The control subjects were included for comparison of peroneal muscle morphology between surgical and non-surgical patients. When this tear occurs the anterior subluxation of the PL tendon impedes the healing of the torn PB. Approval from the Research Ethics Board was obtained and patient consent was waived. Selected foot muscles were scanned using an ultrasound device and the scanned images were processed to measure the thickness and cross-sectional area of the muscles. 25, No. 54, No. [6] The normal flattening of the peroneus brevis tendon in the retromalleolar groove can also simulate a partial thickness tear.

In addition, we have observed the peroneus longus tendon to variably contain surfacing linear intrasubstance signal distal to the peroneal tubercle, as it courses plantar to the cuboid. Bethesda, MD 20894, Web Policies The artificial intelligence was found to be a useful metric of foot posture but was less useful in developing and obese individuals. 9, No. Peroneal tendon tears are a common cause of chronic lateral ankle pain and instability. In patients without prior peroneal tendon surgery, the cleft sign can significantly improve reader diagnostic sensitivity for peroneus brevis tears. LESSON 6, TOPIC 18. Concerning the peroneus brevis, we do not endorse the use of the cleft sign in the retromalleolar location given the routine flattening in this location, increasing susceptibility to partial volume average effects. With the addition of the cleft sign, the performance measures of both readers improved, although not significantly. Within the entire surgical group, the MRI sensitivity, specificity, and accuracy of peroneus longus tendon tears were 16.7%, 93.8%, and 81.6% for Reader 1 and 50.0%, 87.5%, and 81.6% for Reader 2, respectively [Table 4].

There is a longitudinally-oriented partial tear of the peroneus brevis tendon extending from the level of the talofibular ligaments (proximally) to the calcaneo-cuboid joint (distally). Orthop. .switcher .option a {color:#000;padding:3px 5px;} The onset of tears are during adult working years, ages 25 to 60. Venous Anatomy. Patients with low functional demands do well with conservative treatment, while those with high functional demands may benefit from surgery if nonsurgical treatment is unsuccessful. Peroneal Artery: the peroneal artery arises from the tibioperoneal trunk and supplies the muscles of the lateral compartment of the lower leg (peroneus brevis, and peroneus longus). Similar to criteria used in the diagnosis of meniscal tears, the cleft sign requires an intermediate to high intrasubstance signal that breaches the tendon surface. Chauhan B, Panchal P, Szabo E, Wilkins T. J Am Board Fam Med. MRI examinations from 38 control subjects were also reviewed for peroneus brevis muscle quality. The peroneus brevis, sometimes called the fibularis brevis muscle, is the shorter and smaller of two lateral leg muscles running down the outer sides of each lower leg. Case study, Radiopaedia.org (Accessed on 12 Dec 2022) https://doi.org/10.53347/rID-57210. Axial intermediate-weighted fast spin echo; TR 3500 ms, TE 40 ms, slice thickness 4.0 mm, and FOV 16 16 cm. We found no significant correlation between the Goutallier grade of the peroneus brevis muscle and the presence of a peroneus brevis tendon tear and the muscle quality likely depends on more complex factors including tear size/chronicity, limb use, and denervation. Given these challenges, there has been wide variation in the reported performance of MRI in diagnosing peroneal tendon tears. Clinical findings can be vague and the result from MRI at times are not accurate, as suggested from our case of an . These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. [26,27] More recently, imaging the peroneal tendons in oblique planes has shown potential for improved diagnostic performances compared to traditional orthogonal planes. Peroneus brevis muscle quality (Goutallier grade). MRI diagnostic performance for peroneus brevis tears. Control patients had a variety of clinical symptoms but were excluded if the indication suggested lateral ankle pain or clinically suspected peroneal pathology. [29,30] The criteria for signal to be present on two contiguous slices improves specificity of the finding by decreasing the effect of partial volume averaging. To improve the diagnostic accuracy of MRI for peroneus brevis tendon injuries, recent authors have suggested analyzing the peroneus muscle belly for signs of fatty infiltration. The second case was a 46-year-old woman with persistent pain on the lateral aspect of the ankle with a history of a road traffic accident two years ago. .switcher a img {vertical-align:middle;display:inline;border:0;padding:0;margin:0;opacity:0.8;} Surgical management of peroneal tendon tears includes debridement, repair/tubularization, tenodesis, tendon transfer, and autograft/allograft reconstruction.[4,5]. The aim of the case report is to aid other surgeons in surgical treatment and post-operative care. Indian J Musculoskelet Radiol 2022;4:18-25. PMC [16,17] The authors found that patients with peroneus brevis tendon tears on MRI demonstrated significantly higher grades of fatty atrophy compared with controls. Fig. Musculoskeletal (MSK) Foot & Ankle; Tags. Posterior tibialis tenosynovitis and tendinosis . 2020 May 5;100(17):1305-1309. doi: 10.3760/cma.j.cn112137-20191125-02559. This article will discuss manifestations of ankle injury on MRI as well as associated findings that should be addressed. Given the variable criteria for tendinosis and partial tears, readers assessed tendon morphology as tendon thickening +/ increased signal, reflecting tendinosis and intrasubstance tears, and tendon flattening, reflecting the expected flattening of the peroneus brevis in the retromalleolar groove. MRI showed longitudinal tear of peroneus brevis tendon and the patient underwent surgical treatment. No trauma history. 30, No. The Achilles has risk of partial tendon tears as seen here, and then the transaxial . RadioGraphics 2005;25(3): . per night. No significant difference in peroneus brevis muscle quality was present between subjects with and without peroneus brevis tendon tears and between surgical and control patients. Muscles of interest include abductor hallucis, abductor digiti minimi, flexor digitorum brevis and longus, tibialis anterior and peroneus muscles. Axial T2-weighted fast spin echo with fat saturation; TR 4000 ms, TE 85 ms, slice thickness 4.0 mm, and FOV 16 16 cm. Physical signs such as swelling along the course of the peroneal tendon sheath, pain with eversion, and subluxing tendons are diagnostic of . Given the lack of an established definition for partial thickness peroneal tendon tears and our objective of creating such criteria, reviewers were initially asked to assess partial tears based on prior experience, with findings including intratendinous fluid signal clefts and tendon separation into two discrete bundles. No tears of the peroneus longus tendon were identified. In our experience, the peroneus longus tendon often contains increased intrasubstance signal with surface breach as it enters the fibro-osseous tunnel plantar to the cuboid, possibly due to a fanning-out morphology or concurrent tendinosis/tenosynovitis [Figure 4]. Stephen J Pomeranz, MD. [2] Anatomical variations such as the presence of peroneus quartus and peroneal tubercle hypertrophy may also be contributory. abdominal trauma or pulmonary injury (which . . Note the positive cashew nut/boomerang sign. Complete tendon tears were defined as abnormal intermediate or T2-weighted signal replacing the entire cross-sectional area of the tendon, with no visible intact tendon fibers. Unfallchirurg. Bookshelf [19] Although MRI is the gold standard diagnostic imaging tool for assessing the peroneal tendons, distinguishing between pathologies can be challenging.

Res et al. Prevalence and Role of a Low-Lying Peroneus Brevis Muscle Belly in Patients With Peroneal Tendon Pathologic Features: A Potential Source of Tendon Subluxation. The readers assessed for abnormalities of the peroneus brevis and longus tendons and the peroneus brevis muscle belly quality. Ultimately, our goal was to describe MRI findings that could accurately predict a surgically proven tear. Case 1. In patients with prior peroneal surgery, the accuracy of traditional reads was 44.4% and 55.6% for Readers 1 and 2, respectively. When the ankle ligaments are loose, the peroneal tendons are overused causing strain and eventual tear of either tendon. Before The cleft sign is reproducible and practical, quickly detected on routine axial T2-weighted sequences, and can be used in situations where oblique-plane imaging sequences may not be readily available. is surgery needed? The Peroneus Brevis Muscle is also known by the name of Fibularis Brevis Muscle. Second, we aim to examine the value of peroneus brevis muscle status on MRI in assessing tendon tears. 3, Orthopedic Clinics of North America, Vol. All MRI examinations were obtained on a Signa Excite 1.5T scanner (General Electric Medical Systems, Milwaukee, Wisconsin) using system software 12.0 and a 4-channel receive-only extremity coil (Quad Knee Coil, General Electric Medical Systems). In four (80%) of these five cases, the peroneal tendons were either subluxed or dislocated. Enter your email address below and we will send you the reset instructions. No ankle effusion. Controls who had descriptions of peroneal tendon pathology on the MRI report were also excluded from the study. The minimally invasive ATFL reconstruction with partial peroneus brevis tendon has advantages of small trauma, good reconstruction a nd excellent clinical outcomes, thus, is a safe and effective method for the treatment of chronic lateral ankle instability.

With Reader 1, using the cleft sign for assessment in tendons without prior surgery resulted in two additional false positives. Unable to process the form. The use of the cleft sign is limited in a few situations and must be applied with caution in such instances. still painful to exercise, not all the time. No acute fracture. In challenging clinical cases, further evaluation with ultrasound may add value due to its superior spatial resolution and potential for dynamic assessment. The peroneus tertius (PT) muscle, also referred to as the fibularis tertius muscle, is a small muscle of the lower extremity whose principal action is weak dorsiflexion and eversion of the foot [1]. There was no significant difference between the mean Goutallier grades of peroneus brevis muscle bellies in patients with and without peroneus brevis tendon tears during surgery (Reader 1: U = 159.0, P = 0.44; Reader 2: U = 166.5, P = 0.70). [26] Finally, as expected, we found the cleft sign to be highly unreliable in peroneal tendons that have undergone prior surgery [Figure 5]. 27, No. Nine operative reports described prior peroneal surgery on the affected side. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. The performance of the cleft sign for diagnosing peroneal tendon tears in isolation and in conjunction with traditional MRI assessment was compared to that of traditional MRI assessment alone regarding the surgical data. The muscle quality of the peroneus brevis has limited value in MRI diagnosis of peroneal tendon tears. The interobserver reliability for peroneal tendon tears on MRI was moderate for peroneus brevis (0.45) and fair for peroneus longus (0.33). Peroneus brevis tendon tears are acute or chronic, and may be asymptomatic or associated with lateral ankle pain and/or instability. The ankle ligaments and remaining tendons are normal. Patients who had incomplete MRI examinations and those with a time interval of >1 year between MRI and surgery were excluded from the study, yielding 38 subjects with complete pre-operative MRIs available for review. Analogous to post-operative meniscus and rotator cuff cases, the presence of intrasubstance signal is non-specific and can represent granulation tissue and/or fibrosis. If there is cartilage damage or loose or torn ligaments, these will be repaired at the same time. Fluid signal intensity is seen between the torn parts of the peroneus brevis tendon. Yammine K. The accessory peroneal (fibular) muscles: peroneus quartus and peroneus digitiquinti. Case 2.

The readers were asked to re-evaluate the MRI examinations from the surgical cohort for the presence of the cleft sign within the peroneus brevis and longus tendons. 26, No. MRI showed longitudinal tear of peroneus brevis tendon and the patient underwent surgical treatment. The peroneus brevis and peroneus longus tendons are rarely torn simultaneously. Peroneal pathologies include tendinosis/tenosynovitis, tear, and subluxation/ retinaculum injury, with commonly associated soft-tissue findings including lateral collateral ligament complex tears, anterolateral impingement lesions, and synovitis. The peroneus longus and brevis muscle bellies travel . Within the entire surgical cohort, the MRI sensitivity, specificity, and accuracy of peroneus brevis tendon tears were 52.0%, 92.3%, and 65.8% for Reader 1 and 76.0%, 69.2%, and 73.7% for Reader 2, respectively [Table 3]. An official website of the United States government. Case 2. 5, World Journal of Radiology, Vol. Ultrasound or MRI is useful in the diagnosis. Left ankle pain after dropping heavy object on it. However, after 12 weeks my ankle was still swelling and very painful. There is a longitudinally-oriented partial tear of the peroneus brevis tendon extending from the level of the talofibular ligaments (proximally) to the calcaneo-cuboid joint (distally). The interobserver reliability for the cleft sign was moderate for peroneus brevis ( = 0.57). reported diagnostic performances of pre-operative mri for peroneus brevis tendon tears have varied widely, with sensitivities and specificities ranging between 55-97% and 63-90%, respectively. The oblique inframalleolar course of the tendons can predispose to magic angle and partial volume averaging effects. High-resolution US and MR imaging provide crucial information for evaluation of peroneal tendon injuries and disorders, including tendinosis and tenosynovitis, partial- and full-thickness tears, retinacular injuries, and ankle instability, and imaging findings can assist orthopedic surgeons in determining the appropriate treatment. They can be longitudinal or transverse, partial or complete and can be associated with tendon instability 1-5. Application of the cleft sign can significantly increase sensitivity to improve diagnostic accuracy in such cases. The most common is a brevis tendon strain (tear) at the point it attaches to the outside of the foot. In patients without prior peroneal surgery, the sensitivity and specificity of MRI for peroneus brevis tendon tears were 60%/89% and 80%/78% for readers 1 and 2, respectively.

Peroneus brevis tendon split tear at the level of the lateral malleolus. Atrophy was determined based on analysis of the entirety of the muscle belly visualized within the field of view. The split medial and lateral tendon fibers wrap around the intact peroneus longus tendon, and there is a small amount of fluid signal within the common peroneal . High-resolution 1.5-T and 3-T magnetic resonance (MR) imaging with use of dedicated extremity coils and high-resolution ultrasonography (US) with high-frequency linear transducers and dynamic imaging are proved to adequately depict the peroneal tendons for evaluation and can aid the orthopedic surgeon in injury management. A lesion of the What to Expect After Peroneal Tendon Repair Surgery The objectives of this study are to further investigate the performance of pre-operative MRI for peroneal tendon tears and to establish a set of practical and objective imaging criteria for diagnosing peroneal tendon tears. Acute, limited tears of a single peroneal tendon may be debrided and repaired. Philadelphia, PA: Lippincott Williams & Wilkins; 2009:116.) The peroneus brevis muscle (which is also known as the fibularis brevis muscle) finds its origin more distally on the fibula and inserts at the tuberosity of the fifth metatarsal. Mild peroneus longus and brevis tendinosis without tearing [31,32] The evaluation of peroneal tendon tears on MRI in the post-operative setting likely requires surfacing fluid-signal to improve specificity, a topic for future research. bifid peroneus brevis and peroneus quartus tendons), which may also appear as "extra" tendinous bands within the peroneal tendon sheath. Disclaimer, National Library of Medicine Several anatomic variants, including a flat or convex fibular retromalleolar groove, hypertrophy of the peroneal tubercle at the lateral aspect of the calcaneus, an accessory peroneus quartus muscle, a low-lying peroneus brevis muscle belly, and an os peroneum, may predispose to peroneal tendon injuries. McNemars test with binomial distribution was used to test for significant differences in performance measures between traditional MRI reads and using the cleft sign. Two blinded readers retrospectively and independently evaluated pre-operative ankle MRI studies of 38 patients who had undergone peroneal tendon surgery for peroneal tendon tears, peroneus brevis muscle quality, and the cleft sign. All statistical analysis was performed with SPSS statistical software, version 25 (IBM, Armonk, New York).

[16,17] Assessment was based on non-fat saturated axial intermediate-weighted images as we do not routinely include an axial T1-weighted sequence on standard ankle MRI examinations [Figure 1]. Finally, despite excluding cases with excessively long intervals between preoperative MRI and surgery, the intervals in some included cases may still have contributed to false positive or negative MRI reads, potentially related to tendon healing or tearing. In Reader 2, all measures improved (without significance), except specificity, which remained unchanged. Peroneus longus tears are less common than peroneus brevis tears, with much smaller cohorts in the literature, resulting in fewer and even wider variation in reported MRI performance indicators in the literature, with sensitivities ranging from 20% to 80%. Mastery Series: Ankle MRI . , Vol 35, No. We also present the radiographic evaluation of the injury using magnetic resonance imaging (MRI) pre and post-operatively. 6, Journal of the American Academy of Orthopaedic Surgeons, Vol. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. ).

[3] Given the non-specific clinical presentation, the diagnosis of peroneal tendon injury is often delayed. A couple of years ago, I had an MRI done on my left foot. The peroneus brevis (PB) tendon is more likely to get injured than the peroneus longus (PL) due to its crowded location at the level of the retromalleolar groove. The mean peroneus brevis muscle grades in patients without peroneus brevis tendon tears were 0.33 for Reader 1 and 0.40 for Reader 2. No evidence of fracture. The split medial and lateral tendon fibers wrap around the intact peroneus longus tendon, and there is a small amount of fluid signal within the common peroneal tendon sheath. [10,12] Similar MRI findings of peroneus longus tendon tears to peroneus brevis tears have been described. The strength of agreement based on coefficient values was defined as follows: 0, poor; 0.010.20, slight; 0.210.40, fair; 0.410.60, moderate; 0.610.80, substantial; and 0.811.0, almost perfect.[18]. .switcher .option::-webkit-scrollbar-thumb {border-radius:5px;-webkit-box-shadow: inset 0 0 3px rgba(0,0,0,.3);background-color:#888;}.
