Methods and devices for harvesting cancellous bone are disclosed. The bone-harvesting device may include a cannula and a bone receptacle in communication with the cannula, wherein the cannula including a cutting surface positioned at or adjacent the distal end, the cutting surface being oriented at an angle, the angle being greater than 90 degrees relative to the longitudinal axis of the cannula, and the harvested bone is adapted to move from a position adjacent to the cutting surface through the cannula into the bone receptacle. The cutting surface of the cannula may be positioned at or adjacent the distal end, and positioned at least in part radially outward of the outer face of the cannula. The cannula may include a cutting surface positioned at or adjacent the distal end and an occluding geometry that partially occludes the distal end of the cannula adjacent the cutting surface. In addition, a suction port may be provided in communication with the bone receptacle.

A collector used to collect bone includes: a container body defining an interior containment space for receiving and retaining collected bone, and having at least one open end for access and removal of collected bone from the interior containment space; and a cap in covering relation to the open end of the container body such that access to the interior containment space for removal of collected bone is inhibited. The collector includes an intake port defining an opening for receiving therein a distal end of a kerrison rongeur for collecting cut bone from a cutting area thereof, and the cap includes at least one scraper for engaging and dislodging cut bone from the cutting area of a distal end of a kerrison rongeur when received within the intake port. The collector preferably is used with a kerrison-type rongeur for collecting cut bone therefrom.

There is disclosed a system and methods for debriding soft tissue from bone using a high-pressure water debridement system. One embodiment includes a cylindrical sleeve bounded by endcaps and having a drainage port positioned for effluent drainage. A central shaft is configured to receive a bone segment and is disposed along a longitudinal center of the sleeve and rotatively coupled between the endcaps. At least one high-pressure water nozzle is disposed on each side of the sleeve, each of which is positioned to impact the bone segment with a high-pressure water stream. A rotational actuator is configured to rotate the central shaft and the bone segment relative to the sleeve and the water nozzles such that when the high-pressure water nozzles are operational, the high-pressure water streams debride the bone segment. Other embodiments are also disclosed.

A prosthesis for replacing a natural articular surface on a bone may have a joint facing side with an articular surface, a bone anchoring side with a bone engagement surface, and a bone engagement pad secured to at least part of the bone engagement surface. The bone engagement pad may have a transverse portion extending transverse to a length of the bone, and one or more protruding portions extending generally perpendicular to the transverse portion. The transverse portion may have a pad bone-facing surface with a first porosity level, and a pad joint-facing surface on an opposite side of the transverse portion from the pad bone-facing surface, with a second, lower porosity level. The bone engagement surface may be formed via a first manufacturing process selected from the group consisting of forging, milling, and casting. The bone engagement pad may be formed via an additive manufacturing process.

A bone fusion system including a collection vessel, an abrading and harvesting device, tubing and a probe. The abrading and harvesting device includes a needle portion and a sharpened tip. The needle portion has a central bore extending therethrough. The needle portion has a distal end. The sharpened tip is attached to the distal end of the needle portion. The tubing is operably connecting the collection vessel and the abrading and harvesting device. The probe has a threaded portion and a tip portion at a distal end of the threaded portion. The threaded portion has a thread on an outer surface thereof. The tip portion is unsharpened and does not have a thread on an outer surface thereof. The probe is extendible through the central bore.

A collector includes a container body defining an interior containment space and having an open end for access, and a cap in covering relation to the open end and having an opening for receiving therein a distal end of a kerrison-type rongeur. An improvement includes the cap including a first plurality of scrapers in the form of fingers for engaging and dislodging cut bone from the cutting area of the distal end of the rongeur and a second plurality of scrapers in the form of wipers for engaging and dislodging cut bone from the cutting area of the distal end of the rongeur when the distal end of the rongeur is withdrawn through the opening from the collector, the second plurality being arranged so as to permit insertion of the distal end of the rongeur through the opening into the collector without engaging the distal end of the rongeur.

Disclosed is a positioning instrument that includes: two branches equipped at the proximal end thereof with an opposite jaw between which the graft is positioned, the two branches moving closer to one another by a translation movement; and a drill bush including a first hole and a second hole, separated by a distance and sized for the passage and guidance of a bone drill bit. Also disclosed are an instrument kit as well as a method for attaching a graft.

Disclosed are various bioactive and/or biocompatible materials and methods of making the same.

Methods of forming a connective tissue-to-bone interface scaffolds (e.g., ligament-to-bone interface scaffolds, tendon-to-bone interface scaffolds, etc.). These scaffolds (grafts) may be formed from in such a way as to provide both a mineralized and demineralized layer in which the entire graft is flexible, compressible and compliant.
