Hip Joint Method
A method of treating a hip joint of a human patient using a pelvic drill comprising a driving member, a bone contacting and an operating device for operating said driving member. The method comprise the steps of creating a hole passing through the pelvic bone and into the hip joint of the human patient, and providing at least one hip joint surface to the hip joint, through said hole in the pelvic bone of the human patient. In one embodiment the method includes inserting a needle or tube like instrument into the patient's body for filling a part of the patient's body with gas and thereby expanding a cavity within the body.
Hip or shoulder prosthesis and placement instruments
A hip/shoulder prosthesis includes: a head component; a metaphyseal component; a diaphyseal nail, and a locking device. The head component includes: a front face and rear face; with a bore, and first and second shaped recesses in the rear face. The metaphyseal component includes: a central transverse aperture at an angle to the metaphyseal component's axis; a first end configured for threaded engagement within the bore of the head component; and a longitudinal hole that begins at the second end, transects the transverse aperture and reaches the first end, to receive the locking device. The diaphyseal nail is inserted in the femoral or humeral canal, and includes: fastening apertures that receive corresponding screws for fastening the diaphyseal nail to the femur or humerus; a portion configured to he received within, and engage, the transverse aperture of the metaphyseal component, and a transverse hole configured to receive the locking device.
Self-Broaching Neck Preserving Hip Stem
A self-broaching, neck-preserving hip stem includes a set of rasp teeth on a distal-lateral portion of the stem to allow the stem to be impacted into a femur without the use of surgical broaches. The rasp teeth are disposed on a relief surface. The stem includes a length, radius of curvature, and a dual-taper in the anterior-posterior and distal-lateral directions which allow the neck to self-broach and seat itself proximal to the conventional resection level to preserve greater bone stock in the femur.
BONE PREPARATION APPARATUS AND METHOD
A system and method for improving installation of a prosthesis. Devices include prosthesis installation tools, prosthesis assembly tools, site preparation systems, and improved power tools used in implant site preparation, the tools including a secondary motion that preferably includes an ultrasonic vibration.
Methods and tools for hip replacement with superscapsular percutaneously assisted total hip approach
A minimally invasive surgical procedure for replacing a hip joint is provided. A main incision is initiated at a point being a projection of a tip of a greater trochanter and extends proximally about a distance in the range of from 1 cm to 8 cm in line with the femoral axis. An inline capsulotomy is performed, while keeping muscles and posterior capsule intact, to expose the hip joint capsule for accessing the hip joint. The femoral canal is prepared for receipt of a femoral implant. The femoral head is resected and removed out of the acetabulum. A step of acetabular preparation is performed using a retractor comprising two tip rails, each tip rail having a plurality of tines. Related tools, devices, systems and methods are also provided.
Articulating surgical tool
A surgical instrument for releasable connection to a surgical tool having two or more sections that are able to articulate 360 degrees in differing increments and directions. The articulation of the sections allows for the distal end to be spatially offset from the proximal, yet maintain parallel longitudinal axes. The surgical instrument includes a force disc at the proximal end upon which a surgeon can exert a linear force which is transmitted to the distal end having a second tool such as a broach firmly attached thereto.
Electric motor driven tool for orthopedic impacting
An orthopedic impacting tool comprises a motor, an energy storage chamber, a striker, and an anvil. The motor stores energy in the energy storage chamber and then releases it, causing the striker to apply a controlled force on an adapter to create a precise impact for use in a surgical setting. The tool may further comprise a combination anvil and adapter. The tool further allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of a broach, implant, or other surgical implement from the opening. An energy adjustment control of the tool allows a surgeon to increase or decrease the impact energy. A light source and hand grips improve ease of operation of the tool.
METHODS FOR HIP REPLACEMENT WITH ANTERIOR VERTICAL CAPSULE INCISION ? MODIFIED ANATOMICAL DIRECT LATERAL APPROACH (VITOSHA APPROACat
The Modified anatomical direct lateral approach (Vitosha approach), a novel approach in hip arthroplasty, preserving the iliofemoral ligament and restoring the joint capsule, providing higher initial joint stability and easier rehabilitation without the need for post-operative patients' dislocation precautions is provided. The fascial incision curves along the posterior aspect of the greater trochanter and ends at its lower border, preventing a split of vastus lateralis muscle. The anterolateral periosteal layer which conjoins the gluteus medius and vastus lateralis muscles is sharply elevated from the greater trochanter. Gluteus medius muscle and the underlying gluteus minimus are split along its fibers and retracted anteriorly. A vertical capsular incision is made anterior to the femoral shaft, starting from the basicervical line and extending proximally along the longitudinal body axis, with the iliofemoral ligament fibers remained intact.
Patient Adapted Joint Arthroplasty Systems, Devices, Surgical Tools and Methods of Use
Improved systems, methods, and devices for performing joint arthroplasty, including patient-adapted implant components and tools, as well as intraoperative measurement and optimization of joint kinematics are disclosed herein.
ELECTRIC MOTOR DRIVEN TOOL FOR ORTHOPEDIC IMPACTING
An orthopedic impacting tool comprises a motor, a linear motion converter, an air chamber, a compression piston, an impacting element, an anvil element, and a broach adapter. The compression piston may cause the impacting element to apply controlled force on a broach adapter to create a precise opening for subsequently disposing a prosthesis in a patient. The tool allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of the broach and tool from the opening. A force adjustment control of the tool allows a user to increase or decrease the impact force. A light source and hand grips improve ease of operation of the tool.
