The fracture is displaced 1 mm and has a lateral intrascaphoid angle of 55 degrees (a normal angle is about 45 degrees). What is the best next step? Select the Correct AnswerLong-arm cast with thumb spicaPercutaneous in situ screw fixationClosed reduction and pin fixation with castingOpen reduction and internal fixation (ORIF) through a volar approachORIF through a dorsal approachCorrect Answer: ORIF through a dorsal approach Explanation: This scaphoid is fractured through the proximal pole. This portion of the scaphoid has a poor vascular supply and requires surgery. The dorsal approach is most appropriate to access the proximal half of the scaphoid. Percutaneous procedures have a higher risk of unrecognized screw penetration of subchondral bone. The volar approach (interval between the FCR and radial artery)is best for scaphoid waist and distal pole fractures. References: Source: 2016 AAOS OITE Rettig ME, Kozin SH, Cooney WP.
