Abstract
BACKGROUND Peroneal tendinopathies are an under-diagnosed and potentially under-treated pathology. If left untreated it can be a cause of chronic lateral hindfoot pain. Its diagnosis is challenging owing to its low incidence and vague clinical presentation.
CASE SUMMARY We share a case of a patient who experienced a chronic lateral ankle pain exacerbated after alighting from a bus. This patient came to our attention only after failing conservative management on two separate occasions. Plain radiographs and magnetic resonance imaging revealed rupture of the peroneus longus tendon (PLT). Findings were confirmed intra-operatively and tenodesis of the PLT to the peroneus brevis was performed. Patient was kept non-weight-bear with his foot everted and in plantarflexion before being converted to an off-loading boot at two weeks. Patient was started on a progressive rehabilitation programme at six weeks and was able to return to work shortly after with excellent outcomes.
CONCLUSION We aim to share our experience in managing this patient and propose some pointers guided by available literature to avoid missing this commonly overlooked pathology.

Abstract
BACKGROUND Bilateral rupture of the patellar tendon is a very rare injury, which takes place in relation to chronic systemic diseases. These injuries are known causes. Some of these causes are particular in patellar tendon rupture and another are in quadriceps tendon rupture. CASE PRESENTATION 70-year-old diabetic man with simultaneous bilateral patellar tendon disruption of proximal insertion without trauma, receiving long-term hemodialysis. CONCLUSIONS In the present study, we report a case of patellar tendon rupture that has two differences with literature: first, renal failure is a known risk factor for quadriceps tendon rupture, and secondly, the prevalent age of patellar tendon rupture is less than 40 years. Clinical picture, diagnosis, pathogenesis and treatment are discussed. Finally, the literature is reviewed based on previous studies.

Abstract
Peroneal tendon pathology is an important cause of lateral ankle pain and instability. Typical peroneal tendon disorders include tendinitis, tenosynovitis, partial and full thickness tendon tears, peroneal retinacular injuries, and tendon subluxations and dislocations. Surgery is usually indicated when conservative treatment fails. Familiarity with the peroneal tendon surgeries and expected postoperative imaging findings is essential for accurate assessment and to avoid diagnostic pitfalls. Cross-sectional imaging, especially ultrasound and MRI provide accurate pre-operative and post-operative evaluation of the peroneal tendon pathology. In this review article, the normal anatomy, clinical presentation, imaging features, pitfalls and commonly performed surgical treatments for peroneal tendon abnormalities will be reviewed. The role of dynamic ultrasound and kinematic MRI for the evaluation of peroneal tendons will be discussed. Normal and abnormal postsurgical imaging appearances will be illustrated.

Abstract
The os peroneum (OP) is a small sesamoid bone located inside the peroneus longus tendon (PLT), close to the cuboid. The OP can be the cause of pain and can be associated with lesions of the PLT. OP involvement in PLT disorders is frequently misdiagnosed by radiologists. Painful os peroneum syndrome (POPS) refers to a variety of conditions presenting with pain localized on the lateral aspect of the cuboid area. The syndrome can be observed as a consequence of local acute trauma such as ankle sprains or chronic overuse. Because of its intra-tendinous location, in tears of the peroneus longus tendon, the OP can show changes in its morphology or position, depending on the location of the tendon’s tear. Based on the level of the PLT tears, we propose a classification in three subtypes: tears localized proximal to the os peroneum (type I), at its level (type II) or distal to it (type III). These tears present with different changes on OP morphology or location. The aim of this article is to review the normal anatomy, imaging appearance and differential diagnosis of disorders of the OP as well as post-treatment imaging. Teaching points • PLT tears can be classified in three subtypes according to OP location. • POPS is characterized by pain on the lateral aspect of the cuboid. • OP involvement in PLT disorders is frequently misdiagnosed by radiologists.

Abstract
A fracture of the os peroneum is a rare cause of ankle and foot pain and is often overlooked and not assumed. Only a few case reports have discussed the different etiologies, options for diagnosis, and therapeutic interventions for acute cases. We present a case of delayed diagnosis of an os peroneum fracture due to a distortion of the ankle that occurred during air sports. Initial diagnostic testing with magnetic resonance imaging demonstrated a rupture of the peroneus longus tendon with no pathologic abnormalities at the peroneus brevis tendon. During surgery, a combination of an os peroneum fracture and a peroneus brevis tendon split was found and was successfully treated with bone and tendon repair using a lasso stich technique.

Abstract
The peroneocuboid joint, between the peroneus longus tendon and the cuboid bone, has not been anatomically well-defined and no embryological study has been published. Furthermore, the ossification of the os peroneum (a sesamoid inside the peroneus longus tendon) and its associated pathology has been considered to be generated by orthostatic and/or mechanical loads. A light microscopy analysis of serially sectioned human embryonic and fetal feet, the analysis of human adult feet by means of standard macroscopic dissection, X-ray and histological techniques have been carried out. The peroneus longus tendon was fully visible until its insertion in the 1st metatarsal bone already at embryonic stage 23 (56-57 days). The peroneocuboid joint cavity appeared at the transition of the embryonic to the fetal period (8-9th week of gestation) and was independent of the proximal synovial sheath. The joint cavity extended from the level of the calcaneocuboid joint all the way to the insertion of the peroneus longus tendon in the 1st metatarsal bone. The frenular ligaments, fixing the peroneus longus tendon to the 5th metatarsal bone or the long calcaneocuboid ligament, developed in the embryonic period. The peroneus longus tendon presented a thickening in the area surrounding the cuboid bone as early as the fetal period. This thickening may be considered the precursor of the os peroneum and was similar in shape and in size relation to the tendon, to the os peroneum observed in adults. To the best of our knowledge, this is the first study to show that the os peroneum, articular facets of the peroneus longus tendon and cuboid bone, the peroneocuboid joint and the frenular ligaments appear during the embryonic/fetal development period and therefore they can not be generated exclusively by orthostatic and mechanical forces or pathological processes.

Abstract
BACKGROUND Isolated peroneus longus tendon tears are rare and represent a frequently overlooked source of lateral ankle pain and dysfunction. Only few cases of isolated peroneus longus tendon tears have been reported and a common treatment algorithm does not exist. The purpose of this study was to give an overview of the literature and to present our experience of 6 consecutive cases that have been treated successfully by operation and immobilizing cast. METHODS A comprehensive chart review was performed to compile each patient's age, sex, onset of symptoms, time between first symptoms and diagnosis, surgical findings, surgical treatment, length of follow-up, and outcome. The average patient age was 48 years (range 20-63 years). RESULTS Acute tears occurred in 4 cases, and 2 patients reported about a chronic onset of symptoms. The cause for acute tears was an acute inversion ankle sprain in all cases. Diagnosis was made after an average of 11 months (range 0.75-24 months). There were 2 complete tears, and other 4 were incomplete. An os peroneum was present in 2 cases. In 5 of 6 cases, the results after surgical treatment were excellent or good after a mean follow-up of 28.6 months (range 12-78 months). CONCLUSION This study indicates that lateral ankle pain may be due to isolated acute or chronic peroneus longus tendon tears. Thorough clinical and radiological diagnosis is necessary to detect this uncommon injury in time. Patients with acute onset of symptoms and short time between symptoms and diagnosis tend to fare better than the chronic tears and delayed diagnosis. Surgical intervention yields successful and predictable results.

Abstract
BACKGROUND There is a range of different types of tears and pathology of the peroneal tendons. One of the least common types is the tear of the peroneus longus associated with fracture, enlargement, or entrapment at the cuboid tunnel of the os peroneum. The purpose of this study was to evaluate the pathologic patterns of these uncommon peroneal tendon tears, to review the treatment, and to report the patient outcomes following treatment with excision of the os peroneum, debridement, and tenodesis of the peroneus longus to the peroneus brevis. METHODS A 5-year retrospective review of all patients with peroneal tendon tears identified 12 patients operatively treated for peroneus longus tendon tears with associated pathology of the os peroneum, and in whom there was a viable peroneus brevis. All patients were treated with an operative procedure consisting of excision of the os peroneum, debridement, and tenodesis of the peroneus longus to the peroneus brevis. Mean age was 51.5 (range, 33 to 73) years, including 7 males and 5 females. Operative and radiographic records were reviewed to characterize the nature of the peroneus longus tears and associated pathology. Preoperative and postoperative AOFAS hindfoot, SF-36 questionnaires, and Visual Analog Scale (VAS) pain scores were compiled and patient records were reviewed for complications. Mean follow-up after surgery was 63.3 (range, 12 to 114) months. RESULTS All of the patients had an os peroneum associated with a complex, irreparable tear of the peroneus longus tendon. The peroneus longus was typically enlarged, fibrotic, and adhered to the surrounding tissues. In 8 patients, the peroneus longus tendon tear was associated with a fracture of the os peroneum, and in 4 patients with an enlarged and entrapped os peroneum which prevented movement at the cuboid tunnel. Of the 12 patients, 9 had partial tears of the peroneus brevis, which were treated with debridement and suture repair. AOFAS hindfoot scores increased from a preoperative mean of 61 (range, 46 to 75) to a postoperative mean of 91.7 (range, 60 to 100). Mean preoperative SF-36 Physical Component Scores (PCS) increased from 36 to 52 postoperatively. Mean VAS pain scores decreased from a preoperative mean of 6.3 (range, 4 to 8) to a postoperative mean of 1.0 (range, 0 to 4). Complications included 2 patients with sural neuritis and 3 with superficial delayed wound healing successfully treated nonoperatively. CONCLUSION Tears of the distal peroneus longus tendon, which are much less commonly reported than tears of the peroneus brevis, can be associated with pathology of the os peroneum. Excision of the os peroneum, tendon debridement, and tenodesis of the longus to brevis was an effective surgical technique. LEVEL OF EVIDENCE Level IV, case series.

Abstract
Recurrent quadriceps tendon rupture is a debilitating condition that may be challenging to treat, especially in the presence of systemic disease such as diabetes mellitus (Bedi et al., J Shoulder Elbow Surg 19:978-988, 2010; Chbnou and Frenette, Am J Physiol Regul Integr Comp Physiol 5:R952-R957, 2004; Chen et al., J Shoulder Elbow Surg 5:416-421, 2003). Many surgical treatment protocols have been proposed (Azar, in Canale and Beatty, eds., Campbell's Operative Orthopedics, Mosby/Elsevier, Philadelphia, PA, 2008; Ilan et al., J Am Acad Orthop Surg 3:192-200, 2003; Rodeo and Izawa, in Garrett et al., eds., Principles and Practice of Orthopedic Sports Medicine, Lippincott Williams & Wilkins, Philadelphia, PA, 2000). We report the case of a diabetic male with multiple treatment failures. He ultimately sustained a good outcome following treatment with a novel surgical technique that utilized a patella quadriceps tendon allograft. Tendon allograft-to-native bone healing had previously failed in this patient, so we used a bone-tendon construct allograft to provide an allograft bone-to-native bone healing site. Now, 13 months postoperative, the patient has increased strength, minimal pain, 20 ° of extensor lag and 130 ° of flexion.

Abstract
OBJETIVO: Relatar os aspectos morfológicos e avaliar, radiograficamente, o segmento do tendão do músculo fibular longo em contato com o osso cuboide, em cadáveres, e relatar a incidência do ossículo fibular em seu interior, utilizando-se, em alguns casos, da análise histológica. MATERIAIS E MÉTODOS: Foram estudados 50 segmentos tendinosos, sendo radiografados para determinar a presença ou não de ossículo acessório no interior do tendão. As peças nas quais a presença era duvidosa foram seccionadas e submetidas a avaliação macroscópica. Nos casos em que ainda persistiam dúvidas, as peças foram histologicamente avaliadas em hematoxilina-eosina. Um segmento que demonstrou a presença de ossificação também foi analisado histologicamente, a título de ilustração. RESULTADOS: Todos os fragmentos apresentavam dilatação fusiforme na área de curvatura sob o cuboide. Após o estudo radiográfico, 29 desses fragmentos não tinham ossificação, 13 tinham ossificação e 8 eram duvidosos. Após a análise macroscópica, uma peça apresentou ossificação e cinco, não. As duas peças restantes continuaram indefinidas, sendo então analisadas histologicamente, e não se observou ossificação. CONCLUSÃO: Todas as peças demonstraram espessamento local na curvatura sob o cuboide. Entretanto, após análise quantitativa, nos dois casos submetidos ao estudo histológico foi verificado que o tendão era composto de fibrocartilagem e revestido por cartilagem hialina na superfície de contato com o osso. Assim, os segmentos apresentaram o ossículo fibular do ponto de vista morfológico em 28%, e do ponto de vista radiográfico, em 26% dos casos.

Abstract
Injuries to the peroneal tendons are relatively common worldwide but tendon rupture without significant trauma is uncommon. Ankle mechanics can be seriously affected by disruption of one or both of the peroneal tendons although complete rupture can also remain asymptomatic. Accessory ossicles are sesamoid bones and are common findings in routine radiology of the foot and ankle. Although in the vast majority these "os" are normal variants of anatomy, they can lead to painful syndromes and suffer fractures and even undergo degenerative changes in response to overuse and trauma. Although similar syndromes have been discussed in the surgical literature, there is a lack of literature describing the use of modern imaging in the accurate diagnosis and its subsequent assistance towards appropriate management of os peroneum friction syndrome complicated by sesamoid fatigue syndrome. This article presents the plain film, sonographic and magnetic resonance imaging findings in a case of os peroneum friction syndrome complicated by a sesamoid fatigue fracture as well as reviewing the pertinent literature.

Abstract
Acute peroneal tendon tears lay at one end of a spectrum of peroneal tendon pathology. Because a tear represents a mechanical abnormality, surgical treatment is frequently required. Anatomical variants need to be considered as potential causes of lateral ankle pain. Most acute peroneus brevis tears are longitudinal, occur adjacent to the tip of the fibula, and require surgical treatment. Acute peroneus longus tears more commonly occur at the level of the cuboid tunnel and may initially be managed nonoperatively, but, if associated with stenosing tendonitis, may require debridement and tenodesis. Rarely, complete ruptures of both peronei occur and, if there is a significant defect, reconstructive procedures are required.

Abstract
Diseases of the peroneal tendons and superior peroneal retinaculum (SPR) are frequently underdiagnosed causes of lateral ankle pain and instability. Common diseases include tenosynovitis, rupture, and dislocation of the peroneal tendons as well as injuries to the SPR. Many anatomic variants, such as a flat or convex retromalleolar fibular groove, hypertrophy of the peroneal tubercle, an accessory peroneus quartus muscle, a low-lying peroneus brevis muscle belly, or an os peroneum, may be associated with or predispose to lateral ankle disease. Magnetic resonance (MR) imaging is excellent for detecting soft-tissue and bone variants and abnormalities related to the lateral ankle. Knowledge of the MR imaging appearances of these entities aids radiologists in making the precise diagnosis of disorders of the peroneal tendons and SPR. Pitfalls and normal variants of the peroneal tendons, including magic angle phenomenon, pseudosubluxation of the peroneus brevis tendon, a bifurcated or mildly crescentic peroneus brevis tendon, insertion of the peroneus quartus tendon into the peroneus brevis tendon, and the presence of an os peroneum are important to recognize. It is also useful to be familiar with the MR imaging appearances of SPR injuries, which can be an overlooked but treatable cause of lateral ankle pain and instability.

Retrospective review of findings in nine patients (five men, four women; age range, 35-59 years) with os peroneum fracture at radiography and lateral foot pain after injury who had undergone US of the foot was performed. Three patients underwent magnetic resonance (MR) imaging, and two underwent surgery. Os peroneum fragment separation and displacement relative to the calcaneocuboid joint were measured on radiographs. Os peroneum fracture and peroneus longus tendon injuries were characterized with US and MR imaging. Review of 43 foot radiographs obtained in 36 control subjects (eight men, 28 women; age range, 18-84 years) who were found to have an os peroneum at radiography but were asymptomatic in that area was completed to measure os peroneum distance from the calcaneocuboid joint and bipartite os peroneum fragment distraction. RESULTS Os peroneum fragment separation of 6 mm or more or displacement of the proximal fragment by 10 mm or more on a lateral radiograph or 20 mm or more on an oblique radiograph was associated with full-thickness peroneus longus tendon tear in seven of seven patients (100%). Os peroneum fragment separation of 2 mm or less or proximal displacement of 8 mm or less was associated with normal tendons, partial-thickness tears, or tendinosis. In the control subjects, os peroneum location ranged from 7 mm proximal to 8 mm distal to the calcaneocuboid joint on lateral radiographs and from 9 mm proximal to 8 mm distal to the joint on oblique radiographs. Bipartite os peroneum fragment separation was 2 mm or less. CONCLUSION Os peroneum fragment separation of 6 mm or more suggests os peroneum fracture and associated full-thickness peroneus longus tendon tear. Separation of 2 mm or less may be seen with nondisplaced os peroneum fractures and bipartite os peroneum.

Abstract
Fracture of the os peroneum is relatively rare, and a stress fracture of the os peroneum is even rarer. We report a case of stress fracture of the os peroneum in a 38-year-old laborer who had been working in a crouching position. X-rays showed a multipartite os peroneum. Bone scintigram showed uptake at the os peroneum. The histology of the excised os peroneum revealed various stages of fracture healing. Excision of the fractured os peroneum and reconstruction of the peroneus longus tendon by end-to-end suture resulted in an excellent outcome.

Abstract
PURPOSE To determine the magnetic resonance (MR) imaging features that characterize tear of the peroneus longus tendon at the midfoot. MATERIALS AND METHODS Medical records and MR images in nine patients with a tear of the middle segment of the peroneus longus tendon were retrospectively reviewed. All nine patients had undergone routine ankle MR imaging; three had undergone additional oblique coronal MR imaging. Surgical proof of a tear was available for three patients. RESULTS Partial tear was present in four patients, and complete tear was present in five. Partial tears were characterized by heterogeneous signal intensity and thickening of the tendon. Complete tears were characterized by discontinuity of the tendon. 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). The extent of the tear was better assessed with oblique coronal MR images. CONCLUSION The characteristic MR imaging appearance of complete or partial tear of the middle portion of the peroneus longus tendon includes foci of increased signal intensity in the distal tendon, morphologic alterations, and/or discontinuity of tendon. Bone marrow edema along the lateral calcaneal wall may be suggestive of the diagnosis. Additional oblique coronal midfoot MR images may help in assessment of the extent of the tear.

Abstract
The foot and ankle are among the hardest of all areas to image because of the complex three-dimensional anatomy. Magnetic resonance imaging (MRI), with its multiplanar capabilities, excellent soft-tissue contrast, ability to image bone marrow, noninvasiveness, and lack of ionizing radiation, has become a valuable tool in evaluating patients with foot and ankle problems. MRI is more specific than bone scintigraphy and provides more information than ultrasound and computed tomography. Arthroscopy of the ankle is limited to the articular surface and joint space. MRI allows a global evaluation of the bones, tendons, ligaments, and other structures with a single examination that exceeds the capabilities of all other available techniques. This monograph was written to provide a useful guide to basic technique, indications, positioning, anatomy, and interpretation of foot and ankle MRI. The first part describes the performance of the MRI examination with reference to the positioning of the foot, types of coils, and advantages and disadvantages of the different sequences and imaging planes. The next section was written by an experienced foot and ankle orthopedic surgeon and outlines the indications for MRI for the common foot and ankle symptom complexes and the information that the surgeon hopes to obtain from the study. This is followed by a review of pertinent anatomy, as it applies to imaging, with emphasis on osseous structures, ligaments, tendons, and muscles. The final section is a comprehensive review of the common pathologic conditions encountered in the foot and ankle. We hope that radiologists and radiologists-in-training find this article a useful reference tool and gain a better understanding of this complex area of musculoskeletal imaging.
