Disclosed herein are devices and methods of percutaneously treating an ulcerated wound using ultrasonic energy. Some methods include delivering ultrasonic energy to a target tissue located at a position subcutaneous to the ulcerated wound. In some methods, the ultrasonic energy is delivered using an ultrasonic energy delivery device.

Subcutaneous wound debridement

Provided herein are hip implant devices and related surgical methods. The hip implants and methods can optionally be used in patients of Asian descent.

Hip implant

Provided herein is a femoral component of a hip implant device, comprising a neck having a central axis; and a body distal to the neck and having a tapered portion, wherein the body has a largest cross section perpendicular to the neck central axis, the largest cross section perpendicular to the neck central axis having a maximum height dimension and a maximum width dimension, wherein the maximum width dimension is 18.5 mm or less. The hip implant can optionally be used in patients of Asian descent.

A radial-capitellar implant for surgical replacement of the capitellum of the humerus and, optionally, the head of the radius. The radial-capitellar implant includes a capitellar implant or surface replacement arthroplasty of the capitellum and a radial prosthesis for replacement of the head of the radius. In one embodiment the radial prosthesis includes an articular head which moveable articulates with a stem implantable in the radius.

Radial-capitellar implant

Provided are acetabular cup implant assemblies that can be used in hip replacement surgery. Example assemblies comprise a shell and a liner. The liner can be positioned within a shell. Optionally, the liner can be rotated relative to the shell until the liner is seated in the shell in a position where the liner and shell can be secured to one another. Waveform-shaped features of the shell and liner can guide the relative rotation of the liner and shell. Also provided are methods of seating a liner in shell of an acetabular cup implant assembly.

Acetabular cup prosthesis

A prosthetic elbow replacement includes a humeral component having a stem dimensioned to fit within a medullary canal of the humerus and having a yoke connected to the stem wherein the yoke terminates in spaced apart arms. A pivot pin is mounted between the arms for rotational movement with respect to the humeral component. The pivot pin has a transverse throughhole. There is an ulnar component having an ulnar stem including a distal end dimensioned to fit within a medullary canal of the ulna and an opposite proximal end dimensioned to fit within a first end opening of the throughhole. The ulnar component has a mounting cap dimensioned to fit within a second end opening of the throughhole. A fastener connects the ulnar stem and the mounting cap such the proximal end of the ulnar stem is positioned within the first end opening of the throughhole and the mounting cap is positioned within the second end opening of the throughhole. The pivot pin rotates to allow for flexion of the prosthetic elbow replacement, and also allows for axial rotation of the ulna component in the humeral component.

Prosthetic elbow replacement

A multi-functional brace for a joint includes a releasable locking mechanism that allows the brace to be set for static stretch of the joint in either flexion or extension, and a range of motion assembly that allows for free movement of the joint through its natural axis over a controlled range of motion when the locking mechanism is released.

Multi-functional joint brace

A prosthesis for the radius bone in the arm of a patient includes a head shaped for engagement with the capitellum of a humerus bone and the radial notch of the ulna. It also has a curved stem that extends from the head and is tapered with a distally decreasing cross section for insertion into the medullary canal of the radius. A system for implanting the prosthesis requires a resection guide for placing the forearm of the patient in a precise anatomical orientation for resection of the radius bone. The resection guide includes a notched alignment rod attached to an adjustable flange and a reference flange for aligning the forearm for a cut of the radius bone perpendicular with the axis of rotation of the radius bone about the ulna, and for measuring the size of the resection and prosthesis.

Radial implant system

A bone cleaning and drying system for cleaning drying and emptying bones during joint replacement surgery, which includes an applicator for applying compressed gas, namely carbon dioxide, to the intramedullary canal and the cancellous bone, with an applicator nozzle at the distal end, the applicator nozzle having a plurality of end discharge slits and a plurality of angled side discharge slits to provide reverse flow, which provides a pressure gradient from the distal end to the proximal end, which aspirates and directs the entrained air, blood, fluids, fat, marrow, tissue and bone debris onto a drape or a hollow deflector shield surrounding the applicator, the front surface of the hollow deflector shield being apertured to allow the entrained materials to pass therethrough, the interior of the hollow deflector shield being connected to a flexible suction hose, and replaces room air with carbon dioxide in bone.
