US Patent:

7775227, Aug 17, 2010

Filed:

Aug 30, 2007

Appl. No.:

11/848199

Inventors:

David Jackson - Columbia MD, US
Robert O'Toole - Baltimore MD, US
W. Andrew Eglseder - Ellicott City MD, US
Mary Zadnik Newell - Reisterstown MD, US

Assignee:

University of Maryland, Baltimore - Baltimore MD

International Classification:

A45B 3/00

US Classification:

135 66, 135 65

Abstract:

A step-counting ambulatory aid having a ground-contacting surface, which aid comprises a pressure-sensitive switch on the ground-contacting surface and a data recorder located elsewhere on the aid, wherein the pressure-sensitive switch is activated upon contact of the ground-contacting surface of the aid with ground, whereupon the pressure-sensitive switch sends a signal to the data recorder, which records the signal as a step; a method of counting the number of steps taken by a user of an ambulatory aid comprising having the user use an ambulatory aid equipped with a step counter; and a method of establishing a therapeutic regimen for a patient in need of an ambulatory aid comprising determining the number of steps that the patient should take during a set period of time, providing the patient with an ambulatory aid equipped with a step counter, and instructing the patient to take the determined number of steps with the ambulatory aid during the set period of time.

US Classification:

39550032

Abstract:

Apparatuses and methods are disclosed for determining an implant position for at least one artificial component in a joint and facilitating the implantation thereof. The apparatuses and methods include creating a joint model of a patient's joint into which an artificial component is to be implanted and creating a component model of the artificial component. The joint and artificial component models are used to simulate movement in the patient's joint with the artificial component in a test position. The component model and the joint model are used to calculate a range of motion in the joint for at least one test position based on the simulated motion. An implant position, including angular orientation, in the patient's joint is determined based on a predetermined range of motion and the calculated range of motion. In a preferred embodiment, the implant position can be identified in the joint model and the joint model aligned with the joint by registering positional data from discrete points on the joint with the joint model. Such registration also allows for tracking of the joint during surgical procedures.

A61F 236

US Classification:

703 11

Abstract:

An apparatus for facilitating the implantation of an artificial component in one of a hip joint, a knee joint, a hand and wrist joint, an elbow joint, a shoulder joint, and a foot and ankle joint. The apparatus includes a pre-operative geometric planner and a pre-operative kinematic biomechanical simulator in communication with the pre-operative geometric planner.
