The scaphoid is vitally important for the proper mechanics of wrist function. Its unique morphology from its boat like shape to its retrograde blood supply can present with challenges in the presence of a fracture. Almost completely covered with articular cartilage, this creates precise surface loading demands and intolerance to bony remodeling. Fracture location compounds risk of malunion and non-union. Scaphoid fractures may significantly impair wrist function and activities of daily living, with both individual and economic consequences.
舟骨对于腕关节功能的正常力学机制至关重要。其独特的形态,从船形外观到逆行血供,在发生骨折时都会带来挑战。几乎完全被关节软骨覆盖,这对表面负荷提出了精确要求,并且对骨重塑耐受性差。骨折部位会增加畸形愈合和不愈合的风险。舟骨骨折可能会严重损害腕关节功能和日常生活活动能力,对个人和经济都会产生影响。
