Summary Objectives: To investigate whether in navicular bones (NB) from warmbloods, distal border fragmentation is associated with the shape of the proximal articular border or other radiological findings. Methods: Radiographs of the front feet of 325 normal, subadult horses presented for admission as breeding stallions were reviewed. Results: The proximal articular border of the total of 650 NB was classified as straight (n = 278), convex (n = 184), undulating (n = 147) or concave (n = 41). Distal border fragments were present in 57 NB (8.8%). They were significantly more prevalent in NB with a concave (9/41; 22%) or undulating (19/147; 13%) proximal articular border compared to NB with a straight (17/278; 6%) or convex shape (12/184; 7%). No other significant associations were found. Clinical significance: Hypothetically, since a shape-fragment association was found and the distribution of biomechanical forces exerted on the navicular bone are assumed to be shape dependent, distal border fragments may be a result of unfavourable loading of the navicular region.

Equine Industry

Navicular syndrome (navicular disease) plays a major role in the equine industry as a chronic, degenerative, and often career-limiting disease process, affecting a variety of breeds of horses. In addition to clinical signs and diagnostic analgesia, diagnostic imaging plays a key role in the identification of this disease process; radiography is the most widely used imaging modality. In addition to their clinical utility, foot radiographs are a standard element of most pre-purchase examinations. Good radiographic quality and positioning are necessary for accurate interpretation. Radiographic lesions of the navicular bone, such as sclerosis, enlarged synovial invaginations, distal border fragments and flexor cortical erosions, are important to identify and understand because of their potential role in the disease process. This article reviews an approach to radiological evaluation and interpretation of lesions affecting the navicular bone.

The presence of prominent physiological fluid in the posterior part of the superior pericardial recess is known as "high-riding pericardial recess" (HRPR). Even in series studies with high numbers, the amount of liquid in this area was measured with a maximum 1,4 cm in size. Our case report is the biggest HRPR in diameter. HRPRs have clinical significance since they are in the differential diagnosis with lymph nodes and mediastinal cysts. We present a 57-year-old patient with clinical and radiological findings.

Summary Objectives: Macroscopic studies have suggested a link between distal border synovial invaginations of the navicular bone and the distal interphalangeal joint. However, many practitioners consider that these invagi-nations are directly and solely related to navicular disease. The objective was to investigate the communication pattern of these synovial invaginations with the synovial compartments of the distal interphalangeal joint and the navicular bursa, using minimally invasive imaging techniques. Methods: In a prospective observational study, 10 cadaveric limbs with radiographically evident distal border synovial invagi-nations were randomly assigned to computed tomography arthrography or bursography groups, using iopamidol. Results: In 5/5 limbs, contrast medium filled the invaginations following distal interphalangeal arthrography. In the other five limbs, no contrast medium filled the invaginations following bursography. Clinical significance: Contrary to existing beliefs, these invaginations are more likely associated with distal interphalangeal joint synovitis and may not be directly linked to primary navicular bone pathology, but might reflect distal interphalangeal arthropathy. Therefore, the rationale for assessment of these invaginations in stallion selection or pre-purchase examinations as a predictive sign for navicular disease is questionable. Nonetheless, comorbidities are frequent in the equine distal limb. Enlarged synovial invaginations may also be seen in limbs with concomitant primary navicular disease. Further studies are needed to elucidate possible inter-related pathological processes.
