    • Embodiments of the invention are directed to a distal interphalangeal (“DIP”) fusion device for connecting a first bone of a patient to a second, adjacent bone of the patient. The device may include an anchor assembly and a compressor assembly. In another embodiment, a separate compressor base assembly is included. In yet another embodiment an access port assembly is included. The anchor assembly is rotationally coupled to one end of the compressor assembly, such that the compressor assembly may rotate about the anchor assembly within a semi-spherical zone (three degrees of rotational freedom) and translate axially (one degree of translational freedom). In an operative position, the anchor assembly is anchored in an intermediate phalanx of a digit of a patient, the compressor assembly is contained in a distal phalanx of the digit, and the distal phalanx is flexed relative to the intermediate phalanx to create a joint angle. The joint angle is then fixated for fusion by compressing the phalanges together in the flexed position by counter-rotation of the compressor assembly. An advantage of an embodiment of the invention is the screw threads may be matching which eliminates the need to pre-drill two different diameter pilot holes.
    • 本发明的实施例涉及用于将患者的第一骨骼连接到患者的第二相邻骨骼的远端指指(“DIP”)融合装置。 该装置可以包括锚固组件和压缩机组件。 在另一个实施例中,包括单独的压缩机基座组件。 在另一个实施例中,包括进入端口组件。 锚固组件旋转地联接到压缩机组件的一端,使得压缩机组件可以在半球形区域(三个旋转自由度)内围绕锚固组件旋转并且轴向平移(一个平移自由度)。 在操作位置,锚固组件被锚固在患者的数字的中间指骨中,压缩机组件包含在数字的远端指骨中,并且远端指骨相对于中间指骨弯曲以产生关节角度 。 然后通过压缩机组件的反向旋转,将弯曲位置处的趾骨压缩在一起,将关节角度固定以进行融合。 本发明的实施例的优点是螺纹可以是匹配的,这消除了对两个不同直径的导向孔进行预钻孔的需要。
