Overview

• Prevention of complications associated with distal radius fractures should be the treating surgeon's primary concern [1].
• Early diagnosis and treatment are important to avoid long-term consequences of distal radius fracture complications [1].
• Combined median and ulnar nerve palsy related to distal fractures of the radius is exceedingly rare [2].
• Combined median and ulnar nerve palsy complicating distal radius fractures require a standardised management strategy [2].
• Optimal outcomes in the treatment of forearm fracture–dislocations depend on early recognition and management [4].
• Restoration and maintenance of anatomic alignment are key principles for optimal outcomes in forearm fracture–dislocations [4].
• Novel locking plate designs have resulted in a rethinking of the contemporary approach to distal radius fracture fixation [6].
• A certain degree of radial height loss is noted in patients undergoing fracture fixation with volar locking plate for extra-articular distal radius fractures [7].
• An associated ulnar styloid fracture does not affect the outcomes of a distal radial fracture [8].
• Clinicians should be cautious in electing operative treatment for patients with an ulnar styloid fracture [8].
• Bone graft substitutes are primarily used to provide structural stability in distal radius fractures [9].
• Bone graft substitutes may facilitate early return to function in distal radius fractures [9].
• The risk of nonunion is minimal in distal radius fractures [9].
• External fixation supplemented with percutaneous pins is an excellent option for treating displaced fractures of the distal radius [10].
• External fixation supplemented with percutaneous pins yields reliably good results for displaced distal radius fractures [10].
• External fixation supplemented with percutaneous pins has a low reoperation rate for displaced distal radius fractures [10].
• External fixation supplemented with percutaneous pins has a low complication rate for displaced distal radius fractures [10].
• Die punch fragment size is not an indicator of the need for or use of a dorsal approach in distal radius fracture fixation [17].

Anatomy & Pathophysiology

• Prevention of complications associated with distal radius fractures should be the treating surgeon's primary concern, with early diagnosis and treatment being important to avoid long-term consequences [1].
• Combined median and ulnar nerve palsy related to distal fractures of the radius are exceedingly rare but require a standardized management strategy [2].
• Optimal outcomes in the treatment of forearm fracture–dislocations depend on early recognition and management, with restoration and maintenance of anatomic alignment being the key principles [4].
• An associated ulnar styloid fracture does not affect the outcomes of a distal radial fracture and clinicians should be cautious in electing operative treatment for patients with an ulnar styloid fracture [8].
• Bone graft substitutes are primarily used to provide structural stability and perhaps early return to function in distal radius fractures, where the risk of nonunion is minimal [9].
• Metaphyseal collapse ratio, a novel radiographic parameter, was found to provide a reliable measure of metaphyseal comminution, and to be significantly correlated with other radiographic parameters that predict distal radius fracture instability [11].
• There may be radiographic factors other than measures of deformity that some surgeons use to determine recommendations for surgery [12].
• Early accurate diagnosis of intrinsic carpal ligament injuries provides for best outcomes, while delayed diagnosis leads to arthritis within 10 years if not treated [16].
• DP fragment size is not an indicator of the need for or use of a dorsal approach in distal radius fracture fixation [17].
• Pronation effectively increases the proximal 'safe zone' of the posterior interosseous nerve, suggesting the forearm should be placed in pronation to minimize the risk of iatrogenic injury [18].
• CT scan should be requested only by experienced hand surgeons in order to help guide treatment, as it does not significantly improve inter- and intra-observer agreement for all classification systems [20].

Classification

• CT scans do not significantly improve inter- and intra-observer agreement for the AO, Fernandez, and Universal classification systems for distal radius fractures [20].
• The metaphyseal collapse ratio (MCR) is a novel radiographic parameter that provides a reliable measure of metaphyseal comminution [11].
• The metaphyseal collapse ratio (MCR) is significantly correlated with other radiographic parameters that predict distal radius fracture instability [11].

Clinical Presentation

• Bone graft substitutes are primarily used to provide structural stability and perhaps early return to function in distal radius fractures [9].
• Metaphyseal collapse ratio is a novel radiographic parameter that provides a reliable measure of metaphyseal comminution [11].
• Metaphyseal collapse ratio is significantly correlated with other radiographic parameters that predict distal radius fracture instability [11].
• There may be radiographic factors other than measures of deformity that some surgeons use to determine recommendations for surgery in distal radius fractures [12].
• Soft tissue complications encountered during the management of distal radius fractures include tendon injury, nerve dysfunction, vascular compromise, skin problems, compartment syndrome, and complex regional pain syndrome [15].
• Complications associated with soft tissues may be more problematic than the bone injury itself in distal radius fractures [15].
• Early accurate diagnosis of intrinsic carpal ligament injuries provides for best outcomes [16].
• Delayed diagnosis of intrinsic carpal ligament injuries leads to arthritis within 10 years if not treated [16].
• Pronation effectively increases the proximal 'safe zone' of the posterior interosseous nerve [18].
• The forearm should be placed in pronation to minimize the risk of iatrogenic injury to the posterior interosseous nerve [18].
• Monteggia fractures can be easily overlooked if radiographs of the elbow are not taken [19].
• Pre-existing congenital radial head dislocations can lead to inappropriate surgical intervention if not distinguished from Monteggia fractures [19].
• Early recognition and treatment of Essex-Lopresti injury is associated with improved outcomes [21].
