Sacro-iliac joint stabilizing implants adapted for implanting across a SI joint from a dorsal approach. Methods of, and delivery tools adapted for implanting sacro-iliac joint stabilizing implants across a SI joint from a dorsal approach.

Prostheses are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are sized and configured to be press-fit into surgically created pilot SI joint openings in dysfunctional SI joint structures. The prostheses have a pontoon shape with opposed elongated partially cylindrical sections connected by a bridge section. The partially cylindrical sections and, in some instances, the bridge section have a porous structure.

A patient-specific registration jig for registering an orthopaedic surgical instrument with a bony anatomy of a patient includes a head and an adaptor coupled to the head. The head includes a patient-specific contact surface configured to contact a portion of the patient's bony anatomy such that the head can be coupled to the patient's bony anatomy in a unique position. The adaptor includes an elongated shank having a first end coupled to the head and a second end and an adaptor end attached to the second end of the elongated shank. The adaptor end is configured to be received by a clutch of the orthopaedic surgical instrument. A method for registering the orthopaedic surgical instrument using the patient-specific registration jig is also disclosed.

An orthopedic assembly is described that comprises an orthopedic device, an anchor, and a locking mechanism. The orthopedic device can be a plate member having an aperture that is configured to receive the anchor. The anchor can include a head, neck and shank portion. The head portion can include a plurality of arms separated by grooves that are capable of splaying. The assembly is configured such that when the locking mechanism is inserted into the head portion, this causes expansion of the arms of the head. This expansion locks and secures the anchor to the orthopedic device. Various instruments are provided that can deliver the locking mechanism to the anchor, and can provide impact to lock functionality.

In some embodiments, the present disclosure relates to a method of securing an implant into a body of a patient. Initially, the implant is placed into the body of the patient. Then, an impactor tool is used to apply a force to the implant. Subsequent to the application of force to the implant, a portion of an impaction pad on an end of the impactor tool is monitored. When the portion is observed to be deformed, the application of force onto the implant is discontinued.

Disclosed is a universal pedicle screw removal tool comprising a tapered shaft having an “L” shaped tip on one end and a generally square head on an opposite end. A lower section leads to a tapered section which is connected to a handle. The handle may include a set of serrations to provide increased grip. The handle is connected to the head. The tip is sized to engage the channel of a tuliped pedicle screw while the head is sized to engage a ratchet or other torque producing tool. In an alternate embodiment, the tip is “T” shaped. In another alternate embodiment, the handle section includes opposing members extending from the shaft to form a “T” shaped handle. In use, the tip is inserted into the channel of a tuliped pedicle screw while the shaft is rotated to unscrew the pedicle screw from a patient's bone.
