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. abdominal trauma or pulmonary injury (which . Despite the value of MRI, diagnosing peroneal tendon pathology can be challenging due to various anatomic and technical considerations. Peroneus Longus (Blue arrow) is normal. There is a longitudinal split resulting in two components of the Peroneus Brevis tendon (Pink arrows). 2000;21:809815. . There was also no significant difference between the peroneus brevis muscle belly quality of surgical patients and controls (Reader 1: U = 834.0, P = 0.77; Reader 2: U = 768.0, P = 0.55). 12, No. 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. Most tears of the peroneal tendons are partial ruptures of the peroneus brevis tendon called longitudinal tears, tearing along the length of the tendon. (From Tank PW, Gest TR. RadioGraphics 2005;25(3): . No evidence of fracture. Only one patient had an isolated tear of peroneus longus. 54, No. 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. Musculoskeletal (MSK) Foot & Ankle; Tags. and Orthopaedic Surgery (M.M.C., L.D.L. 9, Military Medicine, Vol. Our study is limited by its small sample size and retrospective design, comparable to other similar studies. 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. There is fluid along the tendon sheath. Other injuries have to be sought, e.g. While complete tears are less of a diagnostic dilemma, partial thickness tears can have a variable appearance. Injuries of the peroneal tendon complex are common and should be considered in every patient who presents with chronic lateral ankle pain.
This short muscle is situated right beneath the Peroneus Longus Muscle and belongs to the muscles of the peroneal group which extend to the outer portion of the lower legs and foot. The interobserver reliability for peroneal tendon tears on MRI was moderate for peroneus brevis (0.45) and fair for peroneus longus (0.33). Prevalence and Role of a Low-Lying Peroneus Brevis Muscle Belly in Patients With Peroneal Tendon Pathologic Features: A Potential Source of Tendon Subluxation. 27, No. Split tear peroneus brevis. 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. 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. Normal variants and diseases of the peroneal tendons and superior peroneal retinaculum: MR imaging features. Bookshelf We found no significant difference in Goutallier grades for peroneus brevis muscles both within the surgical cohort between proven cases of peroneus brevis tendon tears and no tears as well as overall between the surgical and control groups. 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. 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. 26, No. FOIA The peroneus muscles originates from lower two-thirds of the lateral surface of the shaft of the fibula and the anterior and posterior inter-muscular septa of the leg.It inserts onto the metatarsals.

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). Peroneal tendon tears are a common but under-recognized source of ankle pain and dysfunction. 39, No. Acad. Our objective is to describe the characteristic MR imaging features of longitudinal tears of the peroneus brevis tendon and to describe pathologic conditions and normal variants that are associated with these tears which may require surgical intervention at the time of primary tendon repair. This website uses cookies to improve your experience while you navigate through the website. [6] The normal flattening of the peroneus brevis tendon in the retromalleolar groove can also simulate a partial thickness tear. 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. The readers were unaware of the criteria for the cleft sign at the time of the initial read. Tears of the peroneus brevis tendon are more frequent than reported in the literature. 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. A peroneus quartus muscle was found in two patients (22%). The Achilles has risk of partial tendon tears as seen here, and then the transaxial . Care should be taken when using the foot posture index to associate pronation with injury risk, and the Achilles tendon and . $74. 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. For the peroneus longus, we do not endorse the use of the cleft sign beyond the peroneal tubercle. PBSS is commonly found in young adults after spontaneous tear or sports related trauma (soccer players and ballet dancers), but .

The first case was a 53-year-old man presented with persistent pain on the lateral aspect on the left ankle during the last four years and difficulty to bear weight during the last year. 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]. Chauhan B, Panchal P, Szabo E, Wilkins T. J Am Board Fam Med. With the addition of the cleft sign, the performance measures of both readers improved, although not significantly. Unfallchirurg. Disclaimer, National Library of Medicine The https:// ensures that you are connecting to the Fig. per night. 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. Am. [16,17] The authors found that patients with peroneus brevis tendon tears on MRI demonstrated significantly higher grades of fatty atrophy compared with controls. The doctor finally ordered an MRI. 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]. We also investigated the relationship between peroneus brevis tendon tears and muscle quality. We hypothesize that this may be a combination of tendinosis/ tenosynovitis and a natural fanning out morphology before the presence of an os peroneum. Enjoy free WiFi, breakfast, and a fitness center. Res et al. Leppilahti J, Flinkkil T, Hyvnen P, Hmlinen M. Zhang W, Bai RJ, Qian ZH, Wang SM, Zhan HL, Li YX. Surg. No acute fracture. Operative treatments include repair of the tendon, resection of the tear, debridement of the tendon, or tenodesis of the peroneus. Foot Ankle. In the subset of patients without prior peroneal surgery, the performance measures improved slightly as a whole for both readers. 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. [15] Based on shoulder rotator cuff literature, it has been hypothesized that the degree of muscle fatty degeneration correlates with tendon pathology and is a predictor of outcome after surgical tendon repair. No history of trauma. Axial intermediate-weighted fast spin echo; TR 3500 ms, TE 40 ms, slice thickness 4.0 mm, and FOV 16 16 cm. [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]. Federal government websites often end in .gov or .mil. Surgical management of peroneal tendon tears includes debridement, repair/tubularization, tenodesis, tendon transfer, and autograft/allograft reconstruction.[4,5]. 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]. In cases where a peroneal tendon tear is undoubtedly present, such as in longitudinal split tearing of peroneus brevis with two distinct bundles, the cleft sign need not be assessed and in fact, may not be present. Surg. All clinical data were accessed through the electronic patient record. Ultrasound or MRI is useful in the diagnosis. I'm worried but I'm so ready to be out of pain and be able to walk, jog, run and so on without pain. In patients without prior peroneal tendon surgery, the cleft sign can significantly improve reader diagnostic sensitivity for peroneus brevis tears.

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. Posterior tibialis tenosynovitis and tendinosis . 1, Foot & Ankle International, Vol. Longitudinal tears of the peroneus brevis tendon were identified in five cases (56%) (Figs. Venous Anatomy. [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. All statistical analysis was performed with SPSS statistical software, version 25 (IBM, Armonk, New York). NewRunner13. [15] However, a limitation of their study was the lack of surgical confirmation of tendon status. A longitudinal split tear is the most frequent type. Peroneal disorder is an under-diagnosed cause of lateral ankle pain where the commonest among peroneal pathology is isolated peroneus brevis tear (70%) followed by mixed peroneal tear (21%) and isolated peroneus longus tear (9%) 4. The peroneus brevis tendon (red arrowheads) is seen in its normal course, heading to its attachment on the base of the 5th metatarsal. 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. The readers assessed for abnormalities of the peroneus brevis and longus tendons and the peroneus brevis muscle belly quality. In our study, the sensitivities and specificities for the two readers in diagnosing peroneus brevis tears in patients without prior peroneal surgery were 60%/89% and 80%/78%, respectively, comparable with that in literature.
