A retrograde resection apparatus may include a cutting blade including a slot defined in the cutting blade, a recess defined in at least a portion of the slot, a screw, including a proximal end and a distal end defining a bore therethrough, a shaft having a distal end and a proximal end, wherein the shaft passes through the bore and the distal end is configured to be received in the recess, and a biasing device configured to bias the shaft against the cutting blade. In addition, the apparatus may include a tether, a first portion of which is affixed to the cutting blade and a second portion of which passes through the bore.

Apparatus and methods for an articulating endodontic file are provided. The apparatus may include two or more file segments. Each file segment may articulate with respect to an adjacent file segment. The articulating file may include a joint between two file segments. The articulating file may include a first joint that allows a file segment to articulate in a first direction. The articulating file may include a second joint that allows a second file segment to articulate in a second direction. The articulating file may be configured such that torque applied to a first file segment is transmitted to one or more other file segments in the file.

A kit including a guiding system and a bone material removal device, including an arcuate element, a guiding element configured to be attached to the arcuate element, a cannula, slidably insertable into a portion of the arcuate element, a cannulated bone material removal device having a longitudinal shaft, which is axially displaceable within the cannula.

Reinforced biocomposite materials. According to at least some embodiments, medical implants are provided that incorporate novel structures, alignments, orientations and forms comprised of such reinforced bioabsorbable materials, as well as methods of treatment thereof.

Methods and devices that displace bone or other hard tissue to create a cavity in the tissue. Where such methods and devices rely on a driving mechanism for providing moving of the device to form a profile that improves displacement of the tissue. These methods and devices also allow for creating a path or cavity in bone for insertion of bone cement or other filler to treat a fracture or other condition in the bone. The features relating to the methods and devices described herein can be applied in any region of bone or hard tissue where the tissue or bone is displaced to define a bore or cavity instead of being extracted from the body such as during a drilling or ablation procedure.

Arthroplasty components include an articular surface and a bone-facing surface. The bone-facing surface bears at least one anchoring element adapted for an oblique implantation trajectory. The articular surface may include a larger radius of curvature in the superior-inferior direction than in the anterior-posterior direction. An inferior chamfer may be present on the articular surface. Instruments and implantation methods are also disclosed.

A single-use handle is configured to attach to a working shaft that can support a sounder for measuring the medullary canal of a proximal radius, and a planarizer that is configured to planarize a proximal edge of the proximal radius after the proximal radius has been resected. The handle can further include a plurality of sizing cavities that are configured to receive the resected bone so as to determine the size of the resected bone. The handle can further include an ejector that is configured to decouple the planarizer from the working shaft.

A method for implanting a medical device for implantation in a mammal joint. The method comprising the steps of creating an opening reaching from outside of the human body into the joint, providing said artificial contacting surface to said joint, fixating the artificial contacting surface to the joint, implanting said reservoir in the human body, and lubricating the artificial contacting surface with use of a lubricating fluid contained in said reservoir.

Aspects of the disclosure relate to surgical cutting systems having a surgical tool and a powered hand piece. The surgical tool can include a cutting tool having a coupling portion for selective connection to a drive pin of the hand piece. The coupling portion defines a tang that is configured to promote self-alignment of the cutting tool and the drive pin during connection of the cutting tool and the hand piece, thus promoting ease of use.

A method of assembling an orthopaedic surgical instrument may include selecting a surgical reamer for use in resecting a portion of a patient's bone. The method may also include aligning an outer sleeve of a stem trial component with a distal end of a shaft of the surgical reamer. The method may also include advancing the outer sleeve into engagement with the distal end of the reamer shaft. The method may also include advancing a central rod of the stem trial component along a passageway defined in the outer sleeve into engagement with the distal end of the reamer shaft. The method may also include threading the central rod into the distal end of the reamer shaft to couple the stem trial component to the surgical reamer for use in resecting the portion of the patient's bone.
