![]() ![]() It is advisable to check the integrity of both proximal and distal radioulnar joints when only one bone is broken. It could be classified as greenstick fracture of the distal radius and ulna or greenstick fracture of mid-third of radius and ulna. ![]() Greenstick fracture is a fracture common in children either the bone is broken or distorted, but the periosteum generally remains intact. It can also result during sudden deceleration of the vehicle when you are driving and your hands are on the steering wheel. The back-fire reportedly forced the crank backward into the chauffeur's palm which in turn produced styloid fracture. The name originated from chauffeurs who got these injuries when the car back-fired while trying to hand-crank the car to start. It is seen that the history of the fracture is same as for Colles' and Smith's fractures and that there are chances of entrapment of tendons and/or the ulnar nerve.Ĭhauffeur's fractures, also known as backfire fracture or a Hutchinson fracture, is a type of fracture of the radial styloid process caused by a direct blow to the radial aspect of the wrist. There are two types of Barton’s fracture: dorsal and palmar. It can generally be treated with closed reduction and cast application.īarton's fracture is an intra-articular fracture of the distal radius with dislocation of the radiocarpal joint usually caused by a fall on an extended and pronated wrist increasing carpal compression force on the dorsal rim with dislocation of the radiocarpal joint. The fracture may be extra-articular, intra-articular, or juxta-articular (called types I, II and III respectively). The X-ray of a Smith's fracture looks quite similar to a Colles fracture other than the displacement showing anteriorly instead of posteriorly. Smith fractures account for less than 3% of all fractures and occur from a fall onto a flexed wrist or a direct blow to the back of the wrist. Since they are caused by the opposite mechanism these fractures are extra-articular transverse fractures or reverse Colles fracture. They are caused when the hand is flexed forward under the wrist. Smith fractures are also known as a Goyrand fracture. To diagnose this kind of fracture, plain x-ray films are usually sufficient, however if there is concern of intra-articular extension then CT is also performed. It has been generally observed that younger patients suffer Colles fractures due to a high impact trauma or fall (contact sports, skiing, horse riding etc). Studies have shown a strong relationship between Colles fractures and osteoporosis so much that when an older male patient presents with a Colles fracture, he should be investigated for osteoporosis because of an increased risk of a hip fracture. It is seen in all adult age groups and particularly in patients with osteoporosis and in elderly women. This fracture was first described in 1814 by an Irish surgeon and anatomist, Abraham Colles and hence the name "Colles" fracture. Types of Distal Radius FracturesĬolles fractures are the most common type of distal radius fractures, in which the broken fragment of the radius tilts upwards and occurs when falling on an outstretched hand. ![]() Depending on the nature and location of this fracture as well as multi-directional forces we exert on this joint in our daily lives, surgery is often required to restore proper anatomic alignment of the bone. ![]() These fractures have varied patterns, so a single form of treatment usually does not apply. ![]()
