A Bartons fracture is a type of wrist injury where there is a broken bone associated with a dislocated bone in the wrist, typically occurring after falling on top of a bent wrist. It is an intra-articular fracture of the distal radius with dislocation of the radiocarpal joint.There exist two types of Bartons fracture – dorsal and palmar, the latter being more common. The Bartons fracture is caused by a fall on an extended and pronated wrist increasing carpal compression force on the dorsal rim. Intra-articular component distinguishes this fracture from a Smiths or a Colles fracture. Treatment of this fracture is usually done by open reduction and internal fixation with a plate and screws, but occasionally the fracture can be treated conservatively. Eponym
It is named after John Rhea Barton (1794–1871), an American surgeon who first described this in 1838. Additional images

Diagnosis
Affected infants have short arms and legs, a small chest with short ribs, and underdeveloped lungs. The spinal bones (vertebrae) in the neck and part of the pelvis (the sacrum) do not harden, or ossify, properly. The face appears flat and oval-shaped, with widely spaced eyes, a small chin, and, in some cases, an opening in the roof of the mouth called a cleft palate. The abdomen is enlarged, and excess fluid may build up in the body before birth (a condition called hydrops fetalis). As a result of these serious health problems, infants are usually premature and stillborn or die shortly after birth from respiratory failure. Some infants have lived for a time, however, with intensive medical support. Babies who live past the newborn period are usually reclassified as having spondyloepiphyseal dysplasia congenita, a related disorder on the spectrum of abnormal bone growth. Treatment
There is no cure or treatment for hypochondrogenesis. References
