FOOSH), high incidence of distal radius fractures in women > 50 years old, DEXA scan is recommended for women with distal radius fractures, fall on outstretched hand (FOOSH) is most common in older population, higher energy mechanism more common in younger patients, includes the radial styloid and scaphoid fossa, 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, transmits load from the carpus to the forearm, based on joint involvement (radiocarpal and/or radioulnar) +/- ulnar styloid fracture, divides intra-articular fractures into 4 types based on displacement, Depressed fracture of the lunate fossa of the articular surface of the distal radius, Fracture-dislocation of radiocarpal joint with intra-articular fx involving the volar or dorsal lip (volar Barton or dorsal Barton fx), Low energy, dorsally displaced, extra-articular fx, Low energy, volarly displaced, extra-articular fx, usually a fall onto outstretched hand

procedure, important adjunct with 80-90% good/excellent results, therefore usually combined with percutaneous pinning technique or plate fixation, apply longitudinal traction and volar/dorsal pressure to the distal fracture fragment, avoid positions of extreme flexion and ulnar deviation (Cotton-Loder Position), no significant benefit of physical therapy over home exercises for simple distal radius fractures treated with cast immobilization, radial shortening is the most predictive of instability, followed by dorsal comminution, dorsal comminution > 50%, palmar comminution, intraarticular comminution, higher loss of reduction with 3 or more of LaFontaine criteria, Meta-analyses and systematic reviews demonstrate no difference in functional outcomes between closed treatment versus

arthroscopically assisted reduction, distal radius extra-articular fracture ORIF with volar approach, distal radius intra-articular fracture ORIF with dorsal approach, associated with plate placement distal to watershed area, the most volar margin of the radius closest to the flexor tendons, can have hyperesthesia over the base of the thenar eminence due to palmar cutaneous nerve injury during retraction of the digital flexor tendons when plating the distal radius, new volar locking plates offer improved support to subchondral bone, intra-articular distal radius fractures with dorsal comminution, can combine with external fixation and percutaneous pinning, volar lunate facet fragments may require fragment-specific fixation to prevent early postoperative failure, screw penetration into the radiocarpal joint or DRUJ, assess intra-articular screws with a 23 degree elevated lateral view, assess dorsal cortex penetration with a skyline view, no benefit of therapist-directed physical therapy compared to home exercise program, distal radius fracture spanning external fixator, distal radius fracture non-spanning external fixator, place radial shaft pins under direct visualization to avoid injury to superficial radial nerve, and excessive volar flexion and ulnar deviation, pin site care comprising daily showers and dry dressings recommended, prevent by avoiding immobilization in excessive wrist flexion and ulnar deviation (Cotton-Loder position), progressive paresthesias, weakness in thumb opposition, paresthesias that do not respond to reduction and last > 24-48 hours, nondisplaced distal radial fractures have a higher rate of spontaneous rupture of the EPL tendon, extensor mechanism is thought to impinge on the tendon following a nondisplaced fracture and causes either a mechanical attrition or a local area of ischemia in the tendon, volar plating with screw fixation that penetrates the dorsal cortex and is proud dorsally, very distal volar plate placement on the radius (distal to watershed line) is associated with FPL rupture, due to physical contact of tendon on plate and subsequent tendinopathy, 90% young adults will develop symptomatic arthrosis if articular stepoff > 1-2mm, delayed procedure associated with higher need for bone grafting and a more difficult procedure, radial shortening associated with greatest loss of wrist function and degenerative changes in extra-articular fractures, AAOS 2010 clinical practice guidelines recommend, early efforts to regain motion of wrist and fingers, Proximal Humerus Fracture Nonunion and Malunion, Distal Radial Ulnar Joint (DRUJ) Injuries. Perilunate instability represents about 7 percent of all injuries to the carpus [ 5 ]. - tenderness of dorsal lunate may suggest Keinbock's dz, while moreulnar tenderness suggests tears of TFC or lunotriquetral ligament; In P_STAR, 2 distraction pins are placed 1.5 cm proximal and distal to the fracture site in clearance of the distal radial physis.
