8/6/2023 0 Comments Smith fracture nerve![]() It can show the presence of a distal radial fracture with volar angulation, the fracture location (extra-, juxta-, or intra-articular), the degree of angulation, and displacement. Diagnosis X-rays ĪP and the lateral radiograph of the wrist can diagnose the fracture. Acute compartment syndrome of the forearm is also seen in Smith's Fracture. Research suggests that up to 15% of Smith's fractures may show symptoms of acute carpal tunnel syndrome from compression to the median nerve. Both radial and ulnar nerve compression are less commonly involved. Įvaluation of the extremity's neurovascular status is critical. There may also be an association of ulnar styloid base fractures. Besides the volar displacement of the distal fragment, disruption of the distal radioulnar joint and the triangular fibrocartilage complex often occurs. The diagnostic criteria for Smith's Fracture is a deformed wrist with swelling visible on the volar side and the prominence of the ulna along the dorsum of the wrist. ![]() The physical exam may reveal pain, swelling, and reduced ROM, and a deformity of the distal forearm, but the direction of volar angulation is difficult to spot visually. Type III - uncommon, less than 2%, is a juxta-articular oblique fractureĬlinical Presentation.Type II - less common, accounting for approximately 13%, is an intra-articular oblique fracture, also referred to as a reverse Barton fracture.Type I - most common type, accounting for about 85% of cases, is an extra-articular fracture through the distal radius.Smith fractures divide into three types : The highest incidence of Smith's fractures is in young males after sustaining high-energy falls and in elderly females who suffering a low energy fall due to osteoporosis Classification Smith fracture makes up approximately 5% of all combined radial and ulnar fractures. The injury site, i.e., the distal radius, is the most common fracture site in the upper limb, accounting for the second most common fracture in the elderly. Injury resulting from a fall on the palm of the hand, the dorsum or ulno‐dorsum of the hand, or a fisted hand or a direct blow to the back of the wrist causing a volar displacement of the distal radius. a direct blow to the dorsal aspect of the wrist.It is also known as a reverse Colles fracture. The Smith's fracture was named by Irish surgeon Robert William Smith in 1847, however, this injury was first named for French Physician Jean-Gaspard-Blaise Goyrand (1746-1814) and is commonly known as a Goyrand fracture in French literature. Smith's Fracture is a fracture of the distal end of the radius caused by a fall on the back of the hand (flexed), resulting in a volar displacement of the fractured fragment.
