“…Metatarsalgia is either a primary or secondary condition that causes great discomfort in daily living [1-4]. Primary metatarsalgia is mainly related to repetitive pressure loading under the MH, which exceeds the focal tissue tolerance and leads to inflammation and pain [1,2,5].…”

Background: Metatarsalgia is related to repetitive high-pressure loading under the metatarsal head (MH) that causes pain. The high pressure under the MH can be reduced by adequately applying metatarsal pads (MPs). Plantar pressure measurements may provide a method to objectively evaluate pressure loading under the MH. However, it is still unclear if the decrease in plantar pressure under the MH after MP treatment is associated with subjective improvement. This study aims to explore the correlations between subjective pain improvement and outcome rating, and the plantar pressure parameters in metatarsalgia patients treated using MPs.

“…The characteristic MR finding is a teardropshaped nodule with low signal intensity on T1-weighted MR images with no fat saturation; it is more easily seen on prone and postcontrast images as it usually presents diffuse enhancement after contrast administration. The prone imaging helps to differentiate Morton neuroma from an intermetatarsal bursitis, which are almost invariably associated (Figure11).An intermetatarsal bursitis can occur as a pathological entity by itself and be responsible for forefoot pain 3,6,8 (Figure 12). …”

“…Areas of very low signal intensity, accentuated in a gradient echo sequence, represent hemosiderin, and when present are characteristic of giant cell tumor of the tendon sheath. 3,6,8 Epidermoid inclusion cysts result from the proliferation of epidermal cells within a circumscribed space of the dermis. They can cause symptoms when they are inflamed or infected.…”

“…These secondary signs of osteomyelitis include a cutaneous ulcer, cellulitis, phlegmon, soft tissue abscess, sinus tract, and cortical interruption. 5,6 Septic arthritis also is most common in diabetic patients and usually is caused by the spread of infection from an adjacent soft tissue or bone source. MR imaging findings of septic arthritis include increased joint fluid and synovial thickening and enhancement.…”

Forefoot pain is a common clinical problem, the etiology of which often is difficult to establish based solely on clinical findings. The causes of forefoot pain include traumatic lesions, Freiberg infraction, infection, arthritis, tendon disorders, nonneoplastic soft tissue masses, and soft tissue and bone neoplasms. This article reviews and illustrates the major nonneoplastic causes of forefoot pain. Traumatic LesionsMetatarsal fractures can be traumatic fractures (e.g., dropping a heavy object on the foot) or stress fractures. Stress fractures can be either fatigue fractures (i.e., abnormal repetitive trauma in normal bone) or insufficiency fractures (i.e., normal stress in a deficient bone). The incidence of metatarsal stress fractures is high in individuals who engage in strenuous exercise for prolonged periods (e.g., military recruits, ballet dancers, gymnasts). In these cases, the metatarsal fracture line is perpendicular to the long axis of the bone, and the fracture occurs more commonly at the middle or distal portions of the second, third, or fourth metatarsal shafts. 1 The main radiographic findings include a well-defined linear lucency with or without an associated fluffy periosteal reaction, a focal linear sclerosis (more often seen in the base of the first metatarsal), and, sometimes, an exuberant callus. Frequently, however, radiographs can be normal in the early stages. On MR imaging, features of metatarsal stress fractures include periosteal and cortical thickening; medullary edema, with or without visualization of the fracture line; and usually associated high-signal-intensity soft tissue on fluid-sensitive images 2 (Figure 1).Sesamoid disorders include fracture, sesamoiditis, and "turf toe." A sesamoid fracture usually occurs secondary All faculty and staff in a position to control the content of this CME activity have disclosed that they have no financial relationships with, or financial interests in, any commercial companies pertaining to this educational activity.Lippincott CME Institute, Inc., has identified and resolved all faculty and staff conflicts of interest regarding this educational activity.

“…Additionally, MTP-PPs are predominantly composed of type-I collagen, represent the larger structure of distal fixation of plantar aponeurosis, and are connected to transverse intermetatarsal ligaments and accessory collateral ligaments of MTP joints [3,4]. MTP-PP ruptures may be related to acute traumatic events or sub-acute repetitive traumas (degenerative lesions) [5,6]. http://dx.doi.org/10.1016/j.ejrad.2014.…”
