摘要:
Patient-specific navigational guide (1 ) for use in spinal surgery, comprising two tubular guiding members (2) integral with a bearing frame (3) and extending from a proximal opening (2a) to a distal opening (2b) for guiding a surgical operation on a patients vertebra (100) contact members (14, 15, 16) designed to match a corresponding plurality of contact areas (103, 102) on the patients vertebra (100) in order to define a unique coupling configuration of the patient-specific navigational guide (1 ) on the patients vertebra (100), wherein said contact members (14, 15, 16) comprise at east one pair of first main contact members (15), designed to abut on a contact area corresponding to the superior articular process (103) or facet of the patients vertebra (100) and a pair of second main contact members (16), designed to abut at least partially on a contact area corresponding to the laminae (102) of the patients vertebra (100). Contact members also comprise auxiliary contact members (14), designed to abut at least partially on a contact area corresponding to the edges (102a) of the patients vertebra (100), in a position different from that of contact of the pair of the second main contact member (16), or to abut at least partially on a contact area corresponding to the transverse process (104).
