Disclosed herein are an implant with a suture passage and a method of attaching sutures to the same. The implant may include a suture pocket having a first pocket, a second pocket, and a suture hole disposed therebetween. The first pocket may have a first wall segment, the second pocket may have a second wall segment, and the suture hole may have a first sidewall segment extending from a first opening to a second opening. The first wall segment, the second wall segment, and the first sidewall segment may form a contiguous wall. A method of attaching a suture to the implant may include placing a tip of a suture needle on the first wall segment, sliding the suture needle into the first opening and pushing the suture needle through the suture hole.

Suture passages for prostheses

Disclosed herein is an implant assembly including an alignment guide for aligning the engagement between a glenosphere and baseplate via a central screw engaged to the baseplate. The glenosphere includes first and second recess portions. The first recess portion of the glenosphere is configured to engage a tapered side surface of the baseplate and the second recess portion of the glenosphere is configured to engage a portion of a head of the central screw projecting outwardly from a top surface of the baseplate when engaged thereto. The portion of the head of the central screw projecting outwardly from the baseplate is slip-fit into the second recess of the glenosphere. This engagement aids the alignment of the glenosphere and the baseplate and helps to ensure the accurate alignment of the tapered engagement of the side surface of the baseplate and the first recess of the glenosphere.

Reverse shoulder baseplate with alignment guide for glenosphere

A trial device and a method for using the device in surgery are disclosed. The device includes a body including a proximal portion and a distal portion. The proximal portion has a post or trunion projecting therefrom. The distal portion extends from the proximal portion and includes a first arm and a second arm, the first and second arms being movable with respect to one another. The body further includes a cavity formed therein so as to extend through the proximal portion and into the distal portion. The device further includes a driver adapted for sliding engagement within the internal cavity of the body such that movement of the driver, preferably in a distal direction, causes movement of a portion of the first arm away from a portion of the second arm.

Expanding trial stem for orthopaedic surgery

Trials for a reverse shoulder system are described. The trials generally include an insert housed within a humeral cup. The insert has a proximal end and a distal end, the proximal end having a concave recess therein adapted to receive a glenosphere prosthesis. The distal end of the insert includes a shaft, the shaft is substantially housed within the confines of the humeral cup. A distal end of the humeral cup is inserted in a humeral stem.

Lateral entry insert for cup trial

An impactor for connection to a concave surface of an implant has a shaft extending along a first axis from a first end to a second end. The shaft first end includes a pivot surface surrounding an internal shaft bore. The internal bore extends along the first axis and is open at the first end and extends towards the second end about the first axis. The internal bore has a pin extending through the shaft and intersecting the bore. A resilient element is mounted in the shaft bore spaced towards the shaft second end. A post is mounted in the shaft bore along the first axis. The post has a first end engaging a threaded bore in the concave surface of the implant. The post has a second end engaging the resilient element and a slot therein slidably engaging the pin and a collar pivotally mounted on the shaft.

Glenosphere inserter and impactor

Humeral head retractor

Described herein is an expandable shoulder trial for a reverse shoulder system including a rotatably adjustable insert housed within a humeral cup. The insert has proximal and distal ends, the proximal end having a concave recess therein adapted to receive a glenosphere prosthesis. The distal end of the insert includes a shaft, the shaft having a helical groove disposed on at least a portion thereof. A distal end of the humeral cup is inserted in a humeral stem. The humeral cup has a proximal end including a recess therein, the recess defined by a circular wall. A guide pin protrudes from the circular wall and is adapted to engage the helical groove of the insert shaft. The proximal end of the insert may rotate along an axis toward the proximal end of the humeral cup and along the same axis away from the proximal end of the humeral cup.

Expandable reverse shoulder trial

An instrument for holding a surgical tool or bone implant includes a handle with a bearing surface formed in one end for engaging the surgical tool. An elastically deformable plate is mounted on the handle body the plate having a catch element formed on a leading end thereof adapted to engage a coupling element formed on the surgical tool. The elastically deformable plate includes a cam follower formed in a recess thereon and includes a deformable spring section intermediate the can elements and the plate end with the catch element. An elongated pivotable loading member is rotatably mounted on the handle body. The loading member includes a cam surface for engaging the cam follower surface on the deformable plate. The cam surface on the loading member is shaped to elastically deform the elastically deformable plate section in a direction away from the plate catch element to thereby load and maintain a connecting force between the plate and the surgical tool or bone implant.

Broach handle with flexure spring

An expandable shoulder trial for a reverse shoulder system is described. The trial includes a rotatably adjustable insert housed within a humeral cup. The insert has a proximal end and a distal end, the proximal end having a concave recess therein adapted to receive a glenosphere prosthesis. The distal end of the insert includes a shaft, the shaft having a helical groove disposed on at least a portion thereof. A distal end of the humeral cup is inserted in a humeral stem. The humeral cup has a proximal end including a recess therein, the recess defined by a circular wall. A guide pin protrudes from the circular wall and is adapted to engage the helical groove of the shaft of the insert. The proximal end of the insert may rotate along an axis toward the proximal end of the humeral cup and along the same axis away from the proximal end of the humeral cup.

A trial device and a method for using the device in surgery are disclosed. The device includes a body including a proximal portion and a distal portion. The proximal portion has a post or trunion projecting therefrom. The distal portion extends from the proximal portion and includes a first arm and a second arm, the first and second arms being moveable with respect to one another. The body further includes a cavity formed therein so as to extend through the proximal portion and into the distal portion. The device further includes a driver adapted for sliding engagement within the internal cavity of the body such that movement of the driver, preferably in a distal direction, causes movement of a portion of the first arm away from a portion of the second arm.
