Rehabilitation as part of treatment for adults with a broken wrist | Cochrane

Particularly in older women, a broken wrist (comprising a fracture at the lower end of the radius, one of the two forearm bones) can result from a fall onto an outstretched hand. Treatment usually includes putting the bone fragments back in place, if badly displaced, and immobilising the wrist in a plaster cast. Surgery may be considered for more seriously displaced fractures. Rehabilitation with interventions such as exercises and other physical interventions is used to help prevent complications, such as stiffness and aching, restore function and speed up recovery.

Differences in Mechanosensory Discrimination Across the Body Surface - Neuroscience - NCBI Bookshelf

The accuracy with which tactile stimuli can be sensed varies from one region of the body to another, a phenomenon that illustrates some further principles of somatic sensation. Figure 9.4 shows the results of an experiment in which variation in tactile ability across the body surface was measured by two-point discrimination. This technique measures the minimal interstimulus distance required to perceive two simultaneously applied stimuli as distinct (the indentations of the points of a pair of calipers, for example). When applied to the skin, such stimuli of the fingertips are discretely perceived if they are only 2 mm apart. In contrast, the same stimuli applied to the forearm are not perceived as distinct until they are at least 40 mm apart! This marked regional difference in tactile ability is explained by the fact that the encapsulated mechanoreceptors that respond to the stimuli are three to four times more numerous in the fingertips than in other areas of the hand, and many times more dense than in the forearm. Equally important in this regional difference are the sizes of the neuronal receptive fields. The receptive field of a somatic sensory neuron is the region of the skin within which a tactile stimulus evokes a sensory response in the cell or its axon (Boxes A and B). Analysis of the human hand shows that the receptive fields of mechanosensory neurons are 1–2 mm in diameter on the fingertips but 5–10 mm on the palms. The receptive fields on the arm are larger still. The importance of receptive field size is easy to envision. If, for instance, the receptive fields of all cutaneous receptor neurons covered the entire digital pad, it would be impossible to discriminate two spatially separate stimuli applied to the fingertip (since all the receptive fields would be returning the same spatial information). Figure 9.4Variation in the sensitivity of tactile discrimination as a function of location on the body surface, measured here by two-point discrimination. (After Weinstein, 1969.)

Radiology Masterclass - Galleries - Trauma X-ray - Upper Limb - Gallery 1 - Clavicle fractures and acromioclavicular joint disruption X-ray

Trauma X-ray - Upper Limb. Some examples of upper limb trauma x-ray. Clavicular fractures and disruption of the AC joint are demonstrated. Clavicle fracture displacement is usually inferior. Displacement of the acromion is usually inferior in acromioclavicular joint dissociation.

Scheme of the arteries of the upper limb

I find it an easy way to study all of the arteries in our body. The name of the arteries are in Latin, but the extra explanation is in Dutch (sorry for that!). If you find any mistakes or tips how to make it better, please put it in the comments, so I can correct them :)
