Several authors demonstrate that 80%% of an axially applied load is taken up by the distal radius at wrist level, while 20%% of the load is supported by the distal ulna.
Non-bridging fixators, with pins only in the radius, permit wrist movement, but the distal pins may be difficult to insert in comminuted fractures and they may also injure the superficial branch of the distal radial nerve.
We hereby report a case of 50-year-old female having a giant-cell tumour in proximal radius along with wrist drop.
One compound fracture of the ulna and dislocation of the radius at the wrist, Dr. D am' s; tight bandaging, gangrene and amputation of the arm.
Inclusion criteria were a malunion following conservative treatment, with a dorsal tilt of the distal radial articular surface of more than 20°, articular displacement of more than 2 mm or incongruity of the distal radio-ulnar joint due to shortening of the distal radius in association with wrist pain and poor wrist range of movement.
Thus, a fall on the outstretched hand may injure the flesh and bones of the hand itself, but a common result is a break at some other site in the arm through which the force is transmitted the scaphoid bone in the wrist; the radius in the forearm just above the wrist; at the elbow; or at the shoulder the breaking point being determined by the direction of force and the anatomy of the individual.
A corrective osteotomy for patients with a malunited radius fracture can improve wrist function and reduce stiffness and pain [4].
As the radius displaced proximally, the wrist becomes increasingly ulnar positive, which in turn leads to direct loading of the distal ulna.
The main outcome was fracture of the wrist (distal radius, distal ulna or carpal bones) diagnosed on conventional X-rays.
Two patients had bone loss in the wrist (distal radius), two patients in the femur (distal femoral metaphysis), and one patient in the foot (first metatarsal).
