Scaphoid nonunions can exist with or without avascular necrosis of the proximal pole, and waist fractures may have an associated humpback deformity. CT best shows the deformity and bone loss, whereas MRI will show avascular necrosis. Operative treatment should be directed at correcting the deformity with open reduction and internal fixation and bone grafting. Vascularized bone grafts should be used in cases of avascular necrosis.
舟骨不愈合可伴有或不伴有近端极的缺血性坏死,腰部骨折可能伴有驼背畸形。CT能最佳地显示畸形和骨质流失,而MRI能显示缺血性坏死。手术治疗应旨在通过切开复位、内固定和植骨来纠正畸形。对于缺血性坏死的病例,应使用带血管蒂骨移植。
