One of the most common fractures is a fracture of the thumb bone. Cracks usually occur due to a fall. Patients are usually children or the elderly. In elderly people, fractures occur due to poorer bone quality. In the younger population, ruptures usually occur as a result of sports activities and traffic accidents. With a clinical examination, pain in the wrist area and limited range of motion can be detected, as well as the frequent presence of edema and deformations in the wrist area. The typical mechanism of such a fracture is droping on the palm of an outstretched hand, which leads to dorsiflexion of the hand, that is, its bending to the upper arm side. This is how a Colles fracture occurs, which is characterized by the dorsal angulation of the fragments, i.e. the displacement of the fragments towards the upper arm. If it happens that the patient falls on the dorsum of a hand, then we are talking about a Smith's fracture in which the volar angulation of the fragments is characteristic, or more precisely, there is a displacement of the fragments towards the palm. Including the clinical examination, it is also necessary to make a radiological analysis, which primarily includes an X-ray taken in two projections. Sometimes it is necessary to make additional diagnostics with CT or MR. We distinguish two primary groups of fractures of the thumb bone in a typical location, namely extra-articular fractures (eg Colles and Smith) and intra-articular fractures (eg Barton). If it is possible to achieve optimal reposition and stability of the fragments, conservative treatment is applied, which consists of repositioning the fragments under local anesthesia and immobilization with a forearm stretcher, followed by a circular cast for a period of 4 to 6 weeks. In the case of multifragmentary fractures and intra-articular fractures, i.e. fractures in which it is not possible to reposition and/or stabilize the fragments, operative treatment is necessary.
