Though a neuroma is a soft-tissue abnormality and will not be visualized by standard radiographs, the first step in the assessment of forefoot pain is an X-ray to detect the presence of arthritis and exclude stress fractures/reactions and focal bone lesions, which may mimic the symptoms of a neuroma.
X-ray showing measurements of HV and IM angles of hallux valgus. Bunions can be diagnosed and analyzed with a simple x-ray , which should be taken with the weight on the foot. [ 10 ] The hallux valgus angle (HVA) is the angle between the long axes of the proximal phalanx and the first metatarsal bone of the big toe.
The metatarsal bones or metatarsus (pl.: metatarsi) are a group of five long bones in the midfoot, located between the tarsal bones (which form the heel and the ankle) and the phalanges ().
The forefoot is the anterior aspect of the foot, composed of the five metatarsal bones, the fourteen phalanges and associated soft tissue structures. [ 1 ] [ 2 ] It is a common site of pathology in podiatry , and is the anatomic region involved in such conditions as hallux valgus , hallux rigidus , and Morton's neuroma , among others. [ 3 ]
X-ray image showing the location of the measurements. X-ray image showing the location of the calcaneal inclination (calcaneal pitch). The radiological assessments have exhibited notable enhancements, converging towards the anticipated normal range.
Weight-bearing lateral X-ray showing the measurement of calcaneal pitch, which is an angle of the calcaneus and the inferior aspect of the foot, with different sources giving different reference points. [18] Calcaneal pitch is increased in pes cavus, with cutoffs ranging from 20° to 32°. [17]
X-ray of the foot by dorsoplantar view, with most common accessory and sesamoid bones. [11]One or both of the sesamoid bones under the first metatarsophalangeal joint (of the great toe) can be multipartite – in two or three parts (mostly bipartite – in two parts).
The X-ray appearance of the developmental "apophysis" in this area may have some resemblance of a fracture, but is not a fracture; it is the secondary ossification center of the metatarsal bone. It is a normal finding that occurs at this site in adolescents. [ 19 ]
