title: Isolated fracture-dislocation of the scaphoid's proximal pole treated by scaphoid internal fixation and scapho-lunate ligament reconstruction.
abstract: We present a case of irreducible palmar dislocation of the proximal fragment of a scaphoid fracture without carpal dislocation. We observed this lesion 2 days after the injury and we immediately operated the patient with a combined volar and dorsal access: using the Henry access we reduced the fracture and we inserted a cannulated screw to synthesize the scaphoid, using the dorsal access we repaired the complete rupture of the scapho-lunate ligament using a mini anchor. Stabilization among scaphoid, lunate and capitate was performed using Kirschner wires. X-ray showed fracture healing after 90 days. No clinical or radiographic evidence of carpal instability was revealed, on standard X-rays or on dynamic evaluations. No sign of avascular necrosis or degenerative arthritis was observed after 9 months.
