A surgical component connecting device, kit, and method are disclosed. The surgical component connective device includes an outer body, a body element, and a support element. The support element is slidably mounted relative to the body element. Two or more surgical component engaging elements provided towards the distal end of the body element, and at least one of the surgical component engaging elements is operably connected to the support element. The two or more surgical component engaging elements have a first state and a second state. The separation of the two or more surgical component engaging elements is greater in the second state than in the first state.

A method, and devices for facilitating the method, for shoulder replacement surgery. The method entails establishing a mechanical support in a the anatomical neck plane of the proximal humeral head, fixing a jig to the mechanical support, where the jig supports a drill guide with its axis perpendicular to the anatomical neck plane, adjusting the drill guide it coincide with the axis of the humeral head, drilling a hole through the humeral head for insertion of a shaft which will support and rotate a reaming bit. The reaming bits used to resurface the humeral head and the glenoid fossa are inserted through the back of the patient, through a gap created between two easily separated muscles, rather than through a gap cut through the subscapularis muscle on the front of the joint. A suitable jig is provided to facilitate the method.

A surgical instrument includes a first member defining an axis and including an end surface and a passageway. A second member is movably disposed within the passageway and includes a tip and a plurality of spaced apart markings. The second member is movable between a first configuration in which the tip extends parallel to the axis and a second configuration in which the tip extends transverse to the axis. The end surface is aligned with a first one of the markings when the second member is in the first configuration and the end surface is aligned with a second one of the markings when the second member is in the second configuration. Methods are disclosed.

A tool for a bone implant includes a sleeve and a transmission rod including a transmission member disposed on an end of a shaft. Another end of the shaft is located outside of the sleeve. The transmission member is received in the sleeve and includes a first compartment and a plurality of first teeth surrounding the first compartment. A drilling rod includes a second compartment and a plurality of second teeth surrounding the second compartment. A coupling portion is disposed between the second compartment and a bit. The coupling portion is coupled with the sleeve. The bit is located outside of the sleeve. Two magnets are disposed in the first and second compartments, respectively. Two same poles respectively of the two magnets face each other.

Surgical tools for removal of tissue, namely instruments, devices and methods for surgical tissue cutting with a cylindrical cutting burr bit extending from an elongated hollow member and connected to a shaft for actuating rotation motion of said burr bit to cut/remove tissue from a target location, while mitigating the harm of damaging surrounding tissue.

A microfracture instrument for applying microfracture therapy to a bone, the microfracture instrument comprising: an elongated shaft comprising a distal end and a proximal end; a needle comprising a body terminating in at least one sharp point, the needle being movably mounted to the distal end of the shaft for movement between an extended position for engaging the bone with the at least one sharp point of the needle and a retracted position for withdrawing the at least one sharp point of the needle from the bone; and a drive shaft movably mounted to the elongated shaft, the drive shaft being connected to the body of the needle so that movement of the drive shaft relative to the elongated shaft moves the needle between its extended position and its retracted position.

A method for providing therapy to a patient, the method comprising: providing microfracture therapy to the acetabular cup of the patient, wherein providing microfracture therapy to the acetabular cup of the patient comprises forming at least one hole extending from the acetabular shelf to the cortical bone bed of the acetabular cup, such that blood may flow from the cancellous bone underlying the cortical bone bed to the surface of the cortical bone bed, whereby to form a blood clot at the surface of the cortical bone bed.

An orthopaedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A method or technique for using the surgical instruments to prepare the bones is also disclosed.

A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member having a plurality of sharp edges is formed from a wear-resistant ceramic material is carried at the distal end of the elongated sleeve. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the sleeve at cutting member at high RPMs to cut bone and other hard tissue. An electrode is carried in a distal portion of ceramic cutting member for RF ablation of tissue when the sleeve and cutting member are is a stationary position. In methods of use, (i) the ceramic member can be engaged against bone and then rotated at high speed to cut bone tissue, and (ii) the ceramic member can be held in a stationary (non-rotating) position to engage tissue and RF energy can be delivered to the electrode to create a plasma that ablates tissue.

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 includes 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. Reamers include reamer heads coupled to various offset shaft configurations.
