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

Systems and methods for monitoring a mechanical force applied to a wound site repairing structure are disclosed. In an embodiment, the systems include a wound site repairing structure, a magnetoelastic sensor coupled to the wound site repairing structure, and a detection system. The detection system includes an excitation coil configured to transmit a signal to the magnetoelastic sensor and a detection coil configured to detect a signal indicative of a mechanical force applied to the wound site repairing structure. The detection system also includes a detection unit configured to detect the signal indicative of the mechanical force applied to the wound repairing structure.

System and method for monitoring of a mechanical force

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.

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.

Method and system for non-invasive determination of a pressure characteristic associated with carpal tunnel (CT) region of a subject. Speed of a shear wave induced in the tissue of the subject and propagating through the CT region is measured at least once. The pressure characteristic is substantially proportional to determined speed.

System and method for non-invasive measurement of carpal tunnel pressure

This document relates to methods and materials involved in tendon or ligament tissue engineering. For example, methods and materials for generating a composite of acellular tendon or ligament allograft slices seeded with cells and bundled into a graft for tissue repair are provided.

Tendon or ligament tissue engineering

A system and method is provided for using dynamic ultrasonic imaging to analyze a subject's carpal tunnel and generate risk factors indicative of the health of the subject's subsynovial connective tissue and the subject's risk of developing carpal tunnel syndrome. The system and method uses speckle imaging techniques to track dynamic structures within the carpal tunnel and statistical analysis techniques to compare the properties of these dynamic structures of the subject to those of normal subjects and subjects having carpal tunnel syndrome.

System and method for analyzing carpal tunnel using ultrasound imaging

This disclosure describes methods for detecting early stages of disease, in particular carpal tunnel syndrome, by using cooperative ultrasound techniques. In a particular embodiment, a grayscale ultrasonogram may be used to detect local anatomical features within the carpal tunnel by physically moving a tendon and identifying the corresponding feature on the ultrasonogram display device. A high-resolution color Doppler ultrasound device may then be used to interrogate features of anatomy surrounding the tendon for disease. In a particular embodiment, the color Doppler ultrasound device may be used to measure the velocities of the tendon and surrounding anatomy, in particular the sub-synovial connective tissue; the resultant data may be used to quantify certain anatomical anomalies, indicative or non-indicative of carpal tunnel syndrome.

Doppler ultrasound for identifying material properties of a carpal tunnel anatomy

A fossa-eminence prosthesis having a nonanatomic surface that is relatively flatter than the native fossa. The articular eminence of the patient can be surgically reduced before implanting the prosthesis.

Temporomandibular joint fossa-eminence prosthesis

The invention provides for a spinal fixation support device to be used in conjunction with spinal fixation instrumentation. The invention further provides for methods of using the spinal fixation support device. In addition, the invention provides for a spinal fixation system that includes a spinal fixation support device of the invention and can further include spinal fixation instrumentation.

Spinal fixation support device and methods of using

A spinal fixation system and methods are provided that includes a plurality of pillars each positioned through a compromised vertebra and into the lower or upper endplates of the neighboring healthy vertebrae.

An apparatus for an expandable screw including an outer screw, a inner screw, and an end nut. An assembly and method for driving and expanding an expandable screw apparatus into a surface or structure. The assembly and method dynamically expand the expandable screw by driving and expanding the expandable screw simultaneously.
