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 patient's vertebra (100)； contact members (14, 15, 16) designed to match a corresponding plurality of contact areas (103, 102) on the patient's vertebra (100) in order to define a unique coupling configuration of the patient-specific navigational guide (1) on the patient's 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 patient's 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 patient's 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 patient's 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).
