2019年4月11日 · Ultrasound (US) is ideal for dynamic evaluation as well as for guiding percutaneous intervention. Technetium-99m-bone scintigraphy may reveal nonspecific increased uptake in pathologic ossicles, and the absence of uptake has been found to have high negative predictive value in accessory navicular syndrome .

In this review, we provide the detailed anatomical structures of the forefoot and their normal appearances on US. We also focus on the most common pathologies affecting the forefoot, including plantar plate tear, sesamoiditis, bone fracture, synovitis, tenosynovitis, bursitis, Morton’s neuromas, and foreign bodies.

2024年11月26日 · Sesamoids, also known as sesamoid bones, are focal areas of ossification within tendons as they pass over joints 1. They can also occur in ligaments and usually measure a few millimeters in diameter. Their function is purported to be to alter the direction of the tendon and modify pressure, thereby reducing friction 2.

2016年1月17日 · MRI is an excellent test to directly evaluate the Lisfranc ligament and other ligaments of the midfoot as well as to diagnose associated fractures and bone bruises, often obviating the need for examination under anesthesia. The best plane is axial (long axis); the best sequence is T2-weighted with fat suppression.

Ultrasono-graphy clearly uncovered the relationship between the sesamoid bone, medial epicondyle, trochlea of the humerus, common flexor tendons, and the ulnar collateral ligament (Fig. 2). Ultrasound examination was performed by slowly flexing and extending the elbow, observing whether the sesamoid bone and the ulnar nerve were in contact in ...

The sesamometatarsal ligaments are seen on MRI in the coronal plane as curved hypointense bands alongside the metatarsal head . On ultrasound, they are distinguishable in the coronal plane as well .

2021年2月10日 · Injuries to the oblique (ODSL) or straight (SDSL) distal sesamoidean ligaments are a recognised cause of distal limb lameness in the horse. However, there are only limited publications addressing common diagnostic features and prognosis.

2009年1月1日 · Ultrasound can be used to diagnose injuries to the deep digital flexor tendon (DDFT), straight distal sesamoidean ligament and branches of the superficial digital flexor tendon using standard pastern ultrasonographic technique.

On ultrasound, only the dorsal component of the Lisfranc ligament complex can be reliably seen. Both feet should be compared. Ultrasound signs of a Lisfranc injury include a thickened or absent dorsal ligament, with or without a medial cuneiform-2 nd metatarsal distance of >2.5 mm which may further widen on weight-bearing .

2007年10月1日 · The ability of ultrasound to image in multiple planes and improvements in both the hardware and software of ultrasound machines allows excellent detail of normal and injured ligaments. In particular, the development of 12- to18-MHz transducers has improved visualization of the smaller ligaments.
