A rotator cuff balloon (10) is disclosed, the rotator cuff balloon (10) includes a limiting structure (100) and a protective structure (200) connected to the limiting structure (100). The limiting structure (100) defines a curvature along a coronal plane. The rotator cuff balloon (10) conforms to the physiological structure of the human shoulder joint limits itself in the subacromial space and can reduce a patient's foreign body sensation, dislocation, functional failure and other adverse events.

A system and method for improving upon an ability of a surgeon to repair traumatic bone injury using new materials, components, and structures. A structure may be used as an implant or a component of an external fixator for a fractured long bone with that structure having anisotropic and viscoelastic properties, such as through additive manufacturing techniques.

A rotator cuff balloon (10) includes a limiting structure (100) and a protective structure (200) connected to the limiting structure (100). The limiting structure (100) has a curvature along a coronal plane (102). This rotator cuff balloon (10) conforms to the physiological structure of the shoulder joint in the human body, limits itself in the subacromial space and can reduce a patient's foreign body sensation, dislocation, functional failure and other adverse events. The protective structure (200) is configured to be supported in the space between the humeral head and the acromion of the shoulder joint in the human body to provide support. Moreover, the humeral head of a patient with a rotator cuff injury is raised, avoiding pain arising from inter-tissue collisions, increasing the moment arm of the deltoid muscle and resulting in immediate improvements in the functions of the patient's shoulder joint. The limiting structure (100) is configured to fit against at least part of the humeral head of the shoulder joint in the human body, thus providing a position-limiting effect and avoiding displacement of the prosthesis.

A prosthesis for at least a portion of a bone, in particular a bone or portion thereof to which, in the natural condition, a tendon of a muscle is attached, wherein the prosthesis is manufactured of a metal or an alloy thereof and is provided with at least one area situated in the surface of the prosthesis that faces outward once the prosthesis has been placed in the body, the area being formed by a layer provided with open spaces that are connected to each other, wherein the open spaces are dimensioned for allowing the growth of bone tissue therein.

Implants are provided. In one exemplary embodiment, an implant includes a spacer configured to be implanted within a joint. The spacer includes an elongated central body extending from a first end to a second end with a longitudinal axis extending therebetween, and first and second wings extending from the first and second ends of the elongated central body, respectively. The elongated central body has a first maximum height in a direction transverse to the longitudinal axis, and each of the first and second wings has a maximum height greater than the first maximum height. When implanted and in the inflated state, at least one of the first wing and the second wing is configured to mechanically interlock with a portion of the anatomy to thereby self-anchor the spacer to the joint and inhibit migration of the spacer. Implant systems and methods for biomechanically augmenting muscle function are also provided.

A structure may be used as an implant or a component of an external fixator for a fractured long bone with that structure having anisotropic and viscoelastic properties, such as through additive manufacturing techniques.

The present invention relates to cruciate ligament retaining knee implants, and instruments and methods for implanting cruciate ligament retaining knee implants.

Disclosed herein are prosthesis, surgical tools, and methods to preserve one or more ligaments of the knee by cutting a least a portion of natural bone during joint surgery, with a portion of the natural bone retained along with the natural attachment of an associated soft tissue structure. The natural bone portion with the associated soft tissue may be re-secured to relevant anatomy during or after knee surgery, which may include retention by features of a tibial prosthesis.

A tibial base plate for attaching to a resected surface at a proximal end of a tibia is provided. The tibial base plate includes a bridge, a pair of compartments and a stem. The bridge has a first contact surface sitting on the resected surface. The compartments are disposed at opposite sides of the bridge and extend in an anterior-posterior direction to form a notch to accommodate a tibial eminence. Each of the compartments has a second contact surface sitting on the resected surface. The stem is connected to the bridge and the compartments and inset into the proximal end of the tibia. The stem has an outer surface. The outer surface is canted towards the notch as insetting into the proximal end of the tibia. The stem is engaged with a cutting slot on the resected surface into the proximal end of the tibia.
