Distal humeral fractures are common fractures especially in immature small breed dogs. The pathogenesis is still unknown. For this study, a three- dimensional bone model of the canine elbow was created and finite element analysis performed in order to determine the relationship between fracture type and bone interactions. Fused and non-fused humeral condyles were considered. A failure criterion...

 Abstract Background: With increasing knowledge concerning fractures of the distal radius, different classifications have been proposed. Reliability of most of these classifications has been assessed. The Fernandez classification has never been assessed for intraobserver and interobserver reliability, although this classification is commonly used. Methods: Five observers including one attending...

BACKGROUND Whether fractures observed in healthy children are associated with microstructural alterations and strength deficit that persists by the end of the growth period is not established. Considering the importance of pubertal timing in bone development, we also quantified the fracture risk related to later menarcheal age (MENA). PARTICIPANTS AND METHODS We followed 124 healthy girls fro...

We investigate whether applying an internal radiocarpal-spanning plate with the wrist in slight extension affects the biomechanical stability of the construct. An unstable distal radius fracture was simulated in 10 cadaveric specimens and immobilized with a radiocarpal-spanning plate holding the wrist in a neutral position. This construct was then physiologically loaded through the wrist flexor...

Background As the triangular fibrocartilage complex (TFCC) anchors the distal radius to the ulna via the radioulnar ligament (RUL), a severely displaced distal fragment of the radius may be associated with a foveal avulsion of the TFCC. The purpose of this retrospective study was to assess, radiographically and arthroscopically, the relationship between displacement of the radius, the ulnar sty...

One of the more difficult problems in wrist surgery is an injury to the ulna side of the wrist associated with a distal radius fracture. When should these be treated acutely and when do they resolve without the need for surgical intervention? The long term disability due to DRUJ problems is significant and includes pain, instability, loss of motion or any combination of the above. Importantly n...

BACKGROUND In the past several years, an increase in open reduction and internal fixation (ORIF) for intra-articular distal radius fractures has been observed. This technique leads to a quicker recovery of function compared to non-operative treatment. However, some patients continue to have a painful and stiff wrist postoperatively. Arthroscopically assisted removal of intra-articular fracture ...

Volar locking plate (VLP) fixation has become the standard surgical treatment for distal radius fractures. However, flexor tendon rupture is one of the major complications following volar plating. This detailed review on the anatomy and morphology of the volar distal radius might facilitate appropriate placement of the volar plate and thereby avoid flexor tendon rupture. We introduce safe and s...

Background: To examine whether interobserver reliability, decision-making, and confidence in decision-making in thetreatment of distal radius fractures changes if radiographs are viewed on a messenger application on a mobile phonecompared to a standard DICOM viewer.Methods: Radiographs of distal radius fractures were presented to surgeons on either a smart phone using a mobilemessenger applicat...

BACKGROUND AND PURPOSE Mechanisms of injury to ulnar-sided ligaments (stabilizing the distal radioulnar joint and the ulna to the carpus) associated with dorsally displaced distal radius fractures are poorly described. We investigated the injury patterns in a human cadaver fracture model. METHODS Fresh frozen human cadaver arms were used. A dorsal open-wedge osteotomy was performed in the dis...
