A method for manufacturing an object having a potential {x} which is generated in response to a field {f} applied thereto is provided. The method includes the step of designing a geometric model of the object. A computerized mathematical model of the object is generated by discretizing the geometric model of the object into a plurality of finite elements and defining nodes at boundaries of the elements, wherein values of the field {f} and potential {x} are specified at the nodes. A material property matrix [k] is then calculated based on the relationship {f}=[k] {x}. Material property coefficients are then extracted from the material property matrix [k] for each finite element in the computerized mathematical model and the extracted material property coefficients are compared to material property coefficients for known materials to match the extracted material property coefficients to the material property coefficients for known materials. Manufacturing parameters corresponding to the matched material property coefficients are then determined. The object is then manufactured in accordance with the determined manufacturing parameters.

A spinal distractor and stabilizer has resilient, conformable bone contacting sections which are separated by an expandable chamber that extends from one of the sections, and which forms a ratchet with the section, ensuring that once expanded by being filled with a substance, cannot contract absent intervention by a medical practitioner. The stabilizer may be filled with a material which solidifies, after which some or all of the device may biodegrade. The device may also be provided in separable portions to facilitate implantation. The conformable sections distribute the distraction and stabilizing force evenly over the bone surface, reducing the incidence of disruption to the integrity of the bone. 1.

Selectively expanding spine cage with enhanced bone graft infusion

Номер: US20180064557A1
Принадлежит: Howmedica Osteonics Corp

A selectively expanding spine cage has a minimized cross section in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. Expanding selectively (anteriorly, along the vertical axis of the spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.

REMOVABLE HEAD ASSEMBLY FOR ARTIFICIAL JOINT

Номер: US20160166390A1
Принадлежит:

In an artificial joint that includes a head assembly attached by taper fit to a proximal portion of a surgically implanted stem, it may become necessary to surgically remove the head assembly. A puller can simultaneously apply a force distally to a non-peripheral portion of a proximal side of the head assembly and proximally to several locations spaced apart around a circumference of the distal side of the head assembly. In some examples, the proximal side of the head assembly includes a plug disposed at the non-peripheral portion. The puller can force the plug into contact with the proximal end of the stem, then apply the distal force through the plug to the stem. In other examples lacking a plug, the non-peripheral portion of the head can deform or break in response to the applied distal force, so that the distal force can apply to the stem. 1. A head assembly for an artificial joint , comprising:a head having a proximal side,the head having a distal side opposite the proximal side, the distal side including a plurality of recessed portions thereon, the recessed portions being spaced apart around a circumference of the distal side,the head having an internal wall that defines an aperture extending from the proximal side to the distal side, the internal wall having a distal portion shaped to form a taper fit with a proximal portion of a stem; anda plug disposed in a proximal portion of the aperture, the plug having a proximal side flush with the proximal side of the head to form a continuous articular surface with the proximal side of the head.2. The head assembly of claim 1 , wherein the internal wall has a proximal portion shaped that is tapered inward.3. The head assembly of claim 2 , wherein the plug and aperture are centered claim 2 , with respect to a longitudinal axis of the head.4. The head assembly of claim 2 , wherein the plug and aperture are decentered claim 2 , with respect to a longitudinal axis of the head.5. The head assembly of claim 4 , wherein ...
