The use of the palmar approach, known as the Moberg approach, for open reduction and osteosynthesis of Bennett's fracture-dislocation has the disadvantage of requiring fairly extensive disinsertion of the thenar muscles and of opening the trapezio-metacarpal articulation. The approach proposed, dorsal and parallel to the ulnar border of the first metacarpal, allows easy access to the fracture site with little or no muscle disinsertion, and without opening the articulation. Once reduction is obtained, it is temporarily held in place by a pin through the dorsal aspect, and then definitively by a screw drawing the fragments together. The one danger in this approach is in damaging a sensory branch of the radial nerve which must be carefully protected.
使用掌侧入路（即莫伯格入路）进行贝内特骨折脱位的切开复位内固定，其缺点是需要相当广泛地分离鱼际肌，并打开大多角骨-掌骨关节。所提出的入路，位于第一掌骨尺侧缘背侧且与之平行，能够在几乎不分离或不分离肌肉的情况下轻松到达骨折部位，且无需打开关节。一旦实现复位，通过一枚穿过背侧的克氏针临时固定，然后通过一枚将骨折块拉拢的螺钉进行最终固定。这种入路的一个风险在于损伤桡神经的一支感觉分支，必须小心加以保护。
