An instrumentation set for preparing a proximal tibia during a bi-cruciate retaining procedure can include a tibial resection block and a stylus. The tibial resection block can be configured to be fixed to an anterior portion of the proximal tibia. The tibial resection block can define a slot that extends in a medial-lateral direction when the tibial resection block is fixed to the proximal tibia. The stylus can have a first block attachment feature and a second block attachment feature. The first block attachment feature can be offset from the stylus a first distance. The second block attachment feature can be offset from the stylus a second distance. The first and second block attachment features of the stylus can be selectively and alternatively received by the slot of the tibial resection block to position the stylus at distinct offset locations relative to the slot.

Methods are provided for extracting bone marrow cells from bone obtained from deceased donors, for preparing the bone marrow for cryopreservation and for obtaining desired cells from cryopreserved and fresh bone marrow.

Systems and methods for designing and implementing patient-specific surgical procedures and/or medical devices are disclosed. In some embodiments, a method includes receiving a patient data set of a patient. The patient data set is compared to a plurality of reference patient data sets, wherein each of the plurality of reference patient data sets is associated with a corresponding reference patient. A subset of the plurality of reference patient data sets is selected based, at least partly, on similarity to the patient data set and treatment outcome of the corresponding reference patient. Based on the selected subset, at least one surgical procedure or medical device design for treating the patient is generated.

Methods are provided for extracting bone marrow cells from bone obtained from deceased donors, for preparing the bone marrow for cryopreservation and for obtaining desired cells from cryopreserved and fresh bone marrow.

A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.

Resected bone and/or tissue removal instruments and related methods are disclosed. The instruments include a first elongate member including a first head portion with a front edge and a first handle portion. The instrument further includes second elongate member rotatably coupled to the first elongate member at a first rotation point, the second member including a second handle portion and an end portion. The instrument also includes a third elongate member rotatably coupled to the first elongate member at a second rotation point, the third member including a second head portion and an end portion. The end portions of the second and third members are rotatably coupled at a third movable rotation point positioned between the first and second rotation points. The second head portion includes an interior surface with a front cutting tooth defining a free end of the second head portion.

The present disclosure teaches a novel medical device for osteotomy, capable of simultaneous aspiration, cauterization, image-acquisition, irrigation and tissue-protection, adapted for ear, nose and throat procedures, but available or other cavity surgeries.

A system for restricting flexion of a spinal segment in a patient comprises a constraint device having a tether structure and a compliance member coupled with the tether structure. The tether structure is adapted to be coupled with a superior spinous process and a sacrum. The system also includes an anchor member that is anchored to the sacrum. The anchor member has an attachment feature that is adapted to couple with the constraint device.

An attainment with an osteotomy surgical instrument for the nasal osteotomy is described; it is set up of at least a couple of lever arms and a couple of sharp spouts that are mutually hinged at least in a rotation fulcrum, where said sharp spouts show an active portion with the cross sectional having a sharp angle, in which the sharp angles of the two sharp spouts are opposed and said active portion extends for a length greater than 30 mm and shorter than 45 mm.

A bone fastener assembly instrument that can assemble a two-component bone fastener during surgery is provided. The bone fastener may be of a type that comprises a threaded bolt and nut for securing an implantable device to bone, such as a spinous process. A method for using the bone fastener assembly instrument is also provided.
