Adjustable drill guide and methods of use thereof

Drill guide assemblies are adjustable for proper alignment of drill holes in the glenoid with the drill holes in the coracoid during a Latarjet procedure. The drill guide has an aimer arm extending from the body of the drill guide which has a fixed angle with respect to a drill sleeve inserted through the guide. The aimer arm can move up or down relative to the drill sleeve while maintaining the fixed angle relative to the drill sleeve by actuation of a translation member on the body.

Methods of tissue repair

Methods of tissue repair. At least one example method includes: pulling a tissue in place over a bone location; abutting a distal end of a guide tool against the tissue at a first location, and driving a first bone anchor through a delivery tube of the guide tool, through the tissue, and into the bone at the first location, the first bone anchor coupled to a first suture line; abutting the distal end of the guide tool against the tissue at a second location displaced from the first location, and then driving a second bone anchor through the delivery tube, through the tissue, and into the bone at the second location, the second bone anchor associated with the first suture line; withdrawing the guide tool away from the tissue; and tightening the first suture line to create a first suture over the tissue.

SURGICAL FASTENING

Methods of joint repair employing sutures and attached fixation devices are discussed. For example, a bone block graft procedure (e.g., Latarjet) is discussed which employs fixation devices to secure contact between graft surfaces of two bones. A suture construct, including a continuous suture loop routed through a first fastener, is secured to a first bone. Looped ends of the suture loop are passed through passageways formed in the two bones. The looped suture ends are further routed through a second fastener. The second fastener is mounted to the second bone and a sliding knot, formed in the looped suture ends, is advanced into contact with the second fastener. The suture is further tensioned using a tensioner device to secure the two bones together.

Stemless Metaphyseal Humeral Implant

A stemless prosthetic shoulder joint may include a prosthetic humeral head and a stemless base. The stemless base may include a collar and an anchor extending from the collar intended to anchor the base into the proximal humerus. The base may include a proximal collar having a proximal surface and a bone-engaging surface opposite the proximal surface. The collar may have a superior portion and an inferior portion, the superior portion defining an arc shape and the inferior portion defining a substantially triangular shape.

Guides and instruments for improving accuracy of glenoid implant placement

A patient specific shoulder guide is provided that includes a hub and a plurality of peripheral members. Each of the peripheral members has a peripheral member height dimension between the patient specific contact surface and a side of the peripheral member opposite the patient specific contact surface. At least one of the peripheral members is a low profile peripheral member in which the peripheral height dimension is less than the peripheral height dimension of at least one other of the peripheral members or is less than the hub height.

APPARATUS FOR TRANS-OSSEOUS ROTATOR CUFF REPAIR
20220000474 · 2022-01-06 · ·

A kit for trans-osseous rotator cuff repair comprising, a handle (101) with a hollow guide (106) and a first connector (104A), a hollow sleeve (103) that passes through the hollow guide (106) in the handle (101), a suture guider (105 and 503) to guide a surgical suture (516) through the hollow sleeve (103), an adaptable hook (107A and 107B) with a narrow slit (118) at one end and a second connector (104B) at opposite end to couple with the first connector (104A), and a pin (901) with first and second apertures (906 and 908) enabling knotless suture of a soft tendon tissue to a bone, wherein the hollow sleeve is adjustable within the hollow guide (106) and a tunnel is created within the bone by creating perpendicularly intersecting a first and a second hole (718 and 706) in that the narrow slit (118) of the adaptable hook (107A and 107B) retrieves the surgical suture (516) from the second hole (706) through the first hole (718) of the tunnel.

System and method for association of a guiding aid with a patient tissue

A guide for placing a landmark(s) in a patient tissue comprises a central portion defining at least one guiding bore configured to receive and guide a tool for placing the at least one landmark in the patient tissue. Extended portions project away from the central portion, each of the extended portions having respective lower base surfaces contoured to mate with the patient tissue, at least the respective lower base surfaces being customized as a function of preoperative imaging of the patient tissue, whereby the guide is specific to the patient.

System and method for association of a guiding aid with a patient tissue

A patient tissue includes a primary patient tissue area and an anatomically differentiated bordering secondary patient tissue area. An apparatus is at least partially customized responsive to preoperative imaging of the patient tissue. Means are provided for mating with the primary patient tissue area in a preselected relative orientation. Means are provided for fixing a first landmark to the primary patient tissue area in at least one of a predetermined marking location and a predetermined marking trajectory. Means are provided for fixing a second landmark to the secondary patient tissue area in at least one of a predetermined marking location and a predetermined marking trajectory. A method of associating a plurality of landmarks with a patient tissue is also provided.

Method and apparatus for fitting a shoulder prosthesis

Method and set of surgical instruments for fitting a shoulder prosthesis, and the shoulder prosthesis. The proposed method seeks to interpose a bone graft between the previously prepared glenoid surface (G) of a scapula (S) of a patient's shoulder and the face of a glenoid prosthetic component opposite the articular surface. The set of instruments permit the bone graft to be taken from the upper epiphysis of the humerus (H), either in situ or ex vivo.

Method and a device for computer assisted surgery
RE048834 · 2021-11-30 · ·

A method for computer assisted determination of values of correction parameters for positioning a medical device relative to a target structure or to a reference base. The method includes a numerical procedure that includes the steps of: i) automatic detection of the projection of a cylindrical reference means in a medical image and determination of a minimum of four characteristic landmarks within the projection of the cylindrical reference means; ii) generating a virtual geometric representation of the cylindrical reference means; iii) determining the virtual projection points representing the characteristic landmarks using a virtual geometric representation of the cylindrical reference means; and iv) iterative determination of the position and orientation of the cylindrical reference means by matching the virtual projection points of the virtual geometric representation of the cylindrical reference means with the characteristic landmarks of the projection of the cylindrical reference means.
