Summary Distal radius fractures are the most common orthopaedic injury and generally result from fall on an outstretched hand. Diagnosis is made clinically and radiographically with orthogonal radiographs of the wrist Treatment can be nonoperative or operative depending on fracture stability and fracture displacement as well as patient age and activity demands Epidemiology Incidence accounts for 17.5% of all fractures in adults Demographics more common in females (2-3:1) bimodal distribution younger patients due to high energy mechanisms older patients due to low energy mechanisms (i.e. FOOSH) Anatomic location 50% are intra-articular Risk factors osteoporosis high incidence of distal radius fractures in women > 50 years old distal radius fractures are a predictor of subsequent fractures DEXA scan is recommended for women with distal radius fractures Etiology Pathophysiology mechanism of injury fall on outstretched hand (FOOSH) is most common in older population higher energy mechanism more common in younger patients Associated conditions DRUJ injuries radial styloid fractures indicates higher energy mechanism soft tissue injuries - seen in 70% TFCC injury (40%) scapholunate ligament injury (30%) lunotriquetral ligament injury (15%) Anatomy Distal radius responsible for 80% of axial load articulates with scaphoid via scaphoid fossa lunate via lunate fossa distal ulna via ulnar/sigmoid notch comprised of 3 columns radial column includes the radial styloid and scaphoid fossa functions attachment sites for the brachioradialis tendon, long radiolunate ligament, and radioscaphocapitate ligament serves as a buttress to resist radial carpal translation functions as a load-bearing platform for activities performed with the wrist in ulnar deviation holds the carpus out to length radially, allowing a more uniform distribution of load across the scaphoid and lunate facets serves as an anchor for the radioscaphocapitate ligament that prevents ulnar translation of the carpus intermediate column lunate fossa functions transmits load from the carpus to the forearm ulnar column includes the TFCC and distal ulna functions stability of the DRUJ forearm motion Classification Fernandez based on mechanism of injury Frykman based on joint involvement (radiocarpal and/or

medically unstable patients unable to undergo a lengthy procedure outcomes important adjunct with 80-90% good/excellent results alone cannot reliably restore 10° palmar tilt therefore usually combined
