Soft tissue retention devices, instrumentation and related methods are disclosed. The devices include a first member having a first head portion and a first shaft portion, the first head portion and the first shaft portion defining a cannulated opening that extends at least partially through the first member, and a second member having a second head portion and a second shaft portion extending from an inner side of the second head portion, the second head portion and the second shaft portion defining a cannulated opening that extends at least partially through the second member.

A compression screw comprising a threaded shaft and a head associated with the proximal end of the shaft. The head has a plurality of outwardly extending projections spaced from one another so as to define a plurality of recesses there between for receiving a screw drive in such a way that rotational force may be transferred from the screw drive to the screw. The projections of the head may be provided with suture fixation holes or a suture coupling may be positioned over the shaft so as to extend between the projections of the head.

A surgical tool, comprising a needle comprising an aperture of sufficient diameter for receiving a screw; a tool, insertable into said aperture for inserting said screw and capable of engaging with and turning the screw; said screw comprising a shaft having threads in a first direction, a head having a bottom face having a flange, and a coil; said coil wound around the screw shaft in an opposing second direction as to the first direction; said coil comprising a coil end which is defined to engage with the flange on the bottom face.

The present invention provides compositions and methods for attaching tendon to bone. The present invention provides compositions and methods for treating rotator cuff injuries. In one embodiment, a method for treating rotator cuff injuries comprises providing a composition comprising PDGF disposed in a biocompatible matrix and applying the composition to at least one site of tendon reattachment on the humeral head.

Disclosed is a system (100) for inserting an adapter. The system can include a docking station (104) and an adapter inserter (102). The docking station can include a handle block (108), a push assembly, and a linkage (320) connecting knob push handle (120) to an engagement tube pull block (324). The engagement tube pull block (324) can extend from the linkage through a portion of the handle bock. The adapter inserter (102) can include a handle body (112), an engagement assembly (116), and a clamp (412). The handle body can be sized to fit in a first recess (110) defined by the handle block body. The engagement assembly (116) can extend from a second end of the handle body (112) and can be configured to engage the adapter (132) at a tip of the engagement assembly. The clamp (412) can be located within and proximate a second end of the handle body so as to engage a portion of the engagement assembly.

The present disclosure relates to an anchor. The anchor includes a suture bridge having a proximal end and distal end. The distal end of the suture bridge has a thickness greater than a thickness of the proximal end of the suture bridge. At least two ribs extend from the proximal end of the suture bridge to a proximal end of the anchor. At least one open helical coil wraps around the at least two ribs and extends, substantially, from the proximal end of the suture bridge to the proximal end of the anchor. The at least one open helical coil defines an internal volume communicating with a region exterior to the anchor through apertures between turns of the at least one open helical coil. The at least two ribs are engagable with a grooved shaft of a driver.

A device, a method of manufacturing, and a surgical method are disclosed in which fibrous connective tissues to be attached to bone are protected by a sleeve. An introducer may be used to assist in placing the fibrous connective tissue into the sleeve.

A biomedical implant (16, 18) is formed from magnesium (Mg) single crystal (10). The biomedical implant (16, 18) may be biodegradable. The biomedical implant (16, 18) may be post treated to control the mechanical properties and/or corrosion rate thereof said Mg single crystal (10) without changing the chemical composition thereof. A method of making a Mg single crystal (10) for biomedical applications includes filling a single crucible (12) with more than one chamber with polycrystalline Mg, melting at least a portion of said polycrystalline Mg, and forming more than one Mg single crystal (10) using directional solidification.

This disclosure relates to surgical fixation systems and methods. The surgical fixation systems can include a fixation device and an adjustable loop connected to the fixation device.

A medical implant for a human shoulder joint includes a first magnetic implant fixed to the non-articular surface of the greater tuberosity of the human shoulder joint, and a second magnetic implant fixed to an outer surface and underside of the acromion of the human shoulder joint. At least one of the first and second magnetic implants generates a magnetic field that urges the first and second magnetic implants away from each other and thereby distracts the humeral head of the human shoulder joint from the acromion.
