Reciprocating rasps for the surgical preparation of the bone prior to the implantation of a glenoid or acetabular component with complex geometry are disclosed. Surgical methods for the use of such reciprocating rasps are also disclosed.

The present invention relates to a device for penetrating human nails as a part of treatment for Onychomycosis, commonly known as fungal nail. The device comprises a reusable electromechanical system and a single use cutting component. The electromechanical system incorporates an electrical motor and drive train to advance the cutting component through the nail. The electromechanical system also incorporates sensors for measuring the cutting resistance for the purpose of preventing the cutting device from overrunning into the nail bed. The device can be used to penetrate the nail in a controlled manner which will create a portal through the nail without penetrating the nail bed below the nail.

A first guide member includes a horizontal body portion and a pair of upright portions. The horizontal body portion has an arcuate configuration and includes a first horizontal surface, a front surface, a rear surface, and a second horizontal surface. The first horizontal surface is flat. The first upright body portion includes a first inwardly extending portion. A first engagement surface of the first inwardly extending portion is configured to rest on a ridge of the alveolar arch of the patient. The second upright body portion includes a second inwardly extending portion. A second engagement surface of the second inwardly extending portion is configured to rest on a ridge of the alveolar arch of the patient. The first guide member lacks a component configured to extend along a lingual or palatal side of the alveolar arch of the patient.

A resection guide includes a first body portion and a second body portion. The first body portion has a first bone engagement structure and defines a first plurality of holes. The second body portion has a second bone engagement structure and defines a second plurality of holes. The first body portion and the second body portion are operable to separate a first anatomical structure of a patient and a second anatomical structure of the patient. A cutting guide defines at least one guide aperture that is operable for guiding a cutting tool for use in resecting a portion of the second anatomical structure of the patient. The cutting guide is positionable relative to the first body portion.

Instrumentation and assembly for arthroscopic elbow surgery which includes a humeral component. The humeral component is installed in a trough formed in the humeral condyle. The trough may be formed by using a plurality of drill pins and a plurality of corresponding cutters (and optionally a template). The two drill pins are passed through the template and drilled into the humerus, and cutters are advanced over the corresponding drill pins to form the trough. The humeral component may be employed in conjunction with an ulnar implant.

Methods and devices for consistently and accurately controlling the depth of the graft tunnel. A sheath is inserted into the bone until a stop member on the sheath contacts the bone. A cutting member is then deployed to drill a larger bore in the tunnel until making contact with the distal end of the sheath. The cutting member may be drawn retrograde within the tunnel, or driven antegrade from an opening opposite the opening in which the sheath resides. The drill and the sheath can then be removed, leaving the tunnel that includes a tunnel portion sized to fit a graft so that the graft fits tightly within the tunnel portion and is flush with the opening of the tunnel.

Surgical tools that increase surgical accuracy for orthopedic procedures involving long bone osteotomy with or without supplementation with allograft or autograft. Two clamps on the operative side are rigidly interconnected to one another with an adjustable rod that is locked into place, preserving length and rotation of the bone. A graft preparation device is used on the operative table. It enables alignment of the graft to preserve the desired mechanical and anatomic axes and to provide rigid fixation of the graft for cutting. Adjustable jigs ensure exact cuts.

A method of implant a knee prosthesis includes forming a bone void at an end of a bone, implanting a void filler in the bone void, and implanting a knee prosthesis onto the end of the bone so that a stem of the knee prosthesis is received by the void filler.

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 surgical cutting device for cutting and removing cartilage from a diseased area. The surgical cutting device includes an elongated shaft having a proximal portion and a distal portion connected between a proximal end and a distal end. A central longitudinal axis extends through the elongated shaft. The proximal portion has a first diameter and the distal portion has a second diameter. The first diameter being larger than the second diameter. The cutting device also includes a cutting tip at the distal end of the elongated shaft. The cutting tip extends along a second axis at an angle relative to the central longitudinal axis and includes a curved blade. The curved blade includes an inner wall extending to a base of the cutting tip.
