Today's hand edition covers four important studies spanning trauma, nerve injury prevention, and surgical decision-making. We examine whether comorbidity indices predict complications in distal radius fracture surgery, review a case of iatrogenic motor branch injury during carpal tunnel release with recommendations for prevention, compare outcomes between capitolunate and four-corner fusion techniques, and present the largest series of complex perilunate fracture-dislocations with dual styloid and scaphoid involvement.
