An implant delivery device for introducing and positioning implants within patients may include a sheath member having a distal end, a proximal end, and a central longitudinal axis, the sheath member defining a lumen along the central longitudinal axis. The implant delivery device may additionally include an implant delivery shaft having a distal end and a proximal end, the implant delivery shaft disposed at least partially within the sheath member and an implant spreader assembly disposed at the distal end of the implant delivery shaft. In some embodiments, the implant delivery device may further include a cap disposed at the distal end of the sheath member, the cap obstructing at least a portion of an opening into the lumen of the sheath member.

A fixator apparatus has a lateral fixator distal apparatus, a lateral fixator proximal apparatus, a lateral fixator joint, a posterior joint, an Essex-lopresti apparatus, a lateral transmission housing, a posterior transmission housing, and a distraction apparatus. The fixator apparatus facilitates reduction, provides two-plan fixation, and increases stability.

An instrument for establishing orientation of a pelvic prosthesis comprises a hub, a first arm attached to and extending from the hub, and a second arm attached to and extending from the hub. The first and second arms define a nominal plane of the apparatus, and may extend from the hub at an angle relative to each other. Distances between the first and second legs and between the first and third legs are adjustable. The first, second, and third legs have tips, and the tips of the first, second, and third legs define a plane having a predefined geometric relationship to the nominal plane of the apparatus.

A method facilitates the treatment of the spine of a patient by providing simultaneous access through at least a first opening and a second opening formed in the patient. For example, the method can include the acts of positioning the patient on a surgical table, providing the first opening into a posterior portion of the patient, providing the second opening into a lateral portion of the patient, inserting a first device through the first opening into the patient to contact the spine in a first direction that is transverse to the coronal plane of the patient, and inserting a second device through the second opening into the patient to contact the spine in a second direction that is transverse to the sagittal plane of the patient, where the first and second openings are accessible simultaneously, and, when the first and second devises are inserted into the patient, the position of the patient is stationary with respect to a portion of the table.

An osteotomy assistance kit includes a bone treatment assistance device and an attaching position confirmation device. The attaching position confirmation device includes a feature point indication rod to be applied via a tip portion to a feature point of the bone, a rod support unit that removably supports the feature point indication rod such that the tip portion is indicating the feature point of the bone, and a second support member that movably supports the rod support unit and indicates one of scales on the rod support unit. The bone treatment assistance device includes cutting slits, and first guide holes that guides first rods set to a predetermined positional relation. The second support member of the attaching position confirmation device is attached to the protrusion of the bone treatment assistance device.
