“…Magnetic resonance imaging (MRI) is the preferred imaging tool for accurate diagnosis, and will show bone marrow edema in both aspects of the synchondrosis in the cases of shearing and mechanical stress, and potentially, also associated pathology of the tibialis posterior, such as signs of tenosynovitis, tendinosis, or tear. In the cases of osteonecrosis, bone marrow edema will be present in the ossicle [9, 13, 14].…”

Anatomical variation in the ankle and foot: from incidental finding to inductor of pathology. Part II: midfooot and forefoot

Accessory anatomical structures in the ankle and foot usually represent incidental imaging findings; however, they may also eventually represent a source of pathology, such as painful syndromes, degenerative changes, be the subject of overuse and trauma, or appear as masses and cause compression syndromes or impingement. This review aims to describe and illustrate the imaging findings related to the presence of accessory ossicles and muscles in the midfoot and forefoot through different techniques, with special attention on those variants that associate factors of clinical relevance or that would trigger challenges in the differential diagnosis.

“…Magnetic resonance imaging can be helpful to detect any bone or soft-tissue edema around the synchondrosis or evidence of osteonecrosis of the AN. 3,7,10 The patient is placed in the supine position with the legs spread. A thigh tourniquet is applied to provide a bloodless surgical field.…”

“…4 Fewer than 1% of AN bones are symptomatic, due to pressure of the bony prominence, bursitis, continuous irritation at the interface between the AN and the navicular, a degenerative or traumatic tear at the synchondrosis, flatfoot due to an abnormal tibialis posterior tendon (TPT) insertion, posterior tibial tendon dysfunction, fracture, osteitis, cartilage cap destruction, or osteonecrosis. 1,3,[5][6][7][8][9][10] Most of the symptomatic cases are type II AN bones and respond to conservative treatment. If conservative measures fail, surgery is indicated.…”

Abstract:The accessory navicular bone is one of the most common accessory ossicles of the foot. Fewer than 1% of accessory navicular bones are symptomatic, and most of these are type II accessory navicular bones. A separation of the synchondrosis is considered one of the main causes of pain. After an injury to the synchondrosis has resulted in a chondroosseous disruption, the combined forces of tension and shear from the posterior tibial tendon and the foot aggravate the injury and prevent it from healing. Fusion of the synchondrosis is a logical surgical treatment option if the pain is recalcitrant to conservative measures. The purpose of this technical note is to report an endoscopic approach to achieve fusion. It has the advantages of better cosmesis, less scar pain, less risk of nonunion, and potential to examine the tibialis posterior tendon and the talonavicular joint.

“…Moreover, MRI is the best non-invasive imaging modality to evaluate osteomyelitis. In fact, the combination of intramedullary patterns of decreased signal intensity on T1-weighted images is the most reliable sign to diagnose osteomyelitis [ 6 ]. The “Penumbra sign” in MRI is helpful in distinguishing between subacute osteomyelitis from other osseous lesions but it is not pathognomonic [ 7 , 8 ].…”

Introduction and importance Navicular bone location of primary subacute hematogenous osteomyelitis uncommon. There are few cases reported in literature. We aim to describe the clinico-radiological features of primary subacute hematogenous osteomyelitis of the navicular bone in a 7-year-old child, to explain our management of this rare disease and demonstrate that medical treatment without surgery is enough. Case presentation A 7-year-old child presented to emergency department. His chief complaint was fever, left limping and foot pain. The positive examination features of were painful palpation of the dorsal side of the foot and a swelling of the homolateral ankle. The erythrocyte sedimentation rate was high. The x-ray revealed a lytic lesion of the left navicular bone. The MRI findings led to the diagnosis of subacute osteomyelitis. Pain relief and normalization of inflammatory markers were obtained after 8 weeks of antibiotic therapy. Complete radiological healing was obtained after 9 months. One year after treatment, the patient was able to practice sports as previously. Clinical discussion Subacute osteomyelitis of the navicular bone in pediatric population is a rare condition. This case shows the importance of early diagnosis thanks to MRI findings and appropriate antibiotic therapy based on the endemic bacteriological profile. Conclusion The navicular bone may develop primary subacute osteomyelitis in immunocompetent child. Early diagnosis is important for prescribing effective conservative treatment.
