The present disclosure relates to a customized medical implant for attachment to and at least partly covering the natural femoral head of a hip joint of a subject. The medical implant includes a dome shaped shell having a height h, an inner equatorial shell radius r.sub.s, an orifice radius r.sub.o, a thickness t.sub.s at the equatorial line, and a thickness t.sub.t at the top of the dome. The implant is constructed such that one or more of the thickness t.sub.s, the thickness t.sub.t, the equatorial shell radius r.sub.s, the orifice radius r.sub.o and the shell height h are customized to the hip joint of the subject based on at least one 3D computed tomography image showing substantially the entirety of the natural femoral head and the acetabulum of said hip joint.

The invention relates to a ceramic surface arthroplasty system, which consists of a convex, hemispherical, metallic implant (1) and a hollow hemispherical metal implant (3). The implants are coated with porcelain or zirconium oxide layer on their friction surfaces to avoid the creation of metallic microparticles. The convex implant (1) has a navel (4) on the thread (6) of which a bone-piercing pre-tensioning needle (7) is screwed and is tightened with a washer (9) at the area of the major trochanter or bulge. Further, it has protruding ribs (5) immersed on the surface of the head.

A holder system for an implantable device, said holder system comprising a first component arranged to act as a clamp and a second component arranged to interact with the first component to prevent movement of said first component when clamped.

The invention relates to a method and a device for producing an implant, wherein a natural bone microstructure of a natural bone region is detected (S1), an implant region in the natural bone region is marked (S2), the detected bone microstructure in the marked implant region is analysed to determine reproduction parameters (S3), and on the basis of the determined reproduction parameters, an artificial microstructure for producing the implant is created (S4).

A lubrication device for lubricating a joint of a human or mammal patient, which is entirely implantable in a patient's body, comprises a reservoir for storing a lubricating fluid and a fluid connection for introducing the lubricating fluid into the joint when the device is implanted in the patient's body. Further, the fluid connection comprises a fluid connection device connecting the reservoir with the joint such that a lubricating fluid flow is established from the reservoir into the joint. The fluid connection comprises either an infusion needle adapted to be intermittently placed into the joint for injecting the lubricating fluid, or a tube adapted to be permanently placed into the joint for continuously injecting the lubricating fluid.

A locking member for implantation in a hip joint of a patient is disclosed. The locking member is adapted to assist in the fixation of a medical device, having an artificial hollow caput femur surface, to the collum and/or caput femur, wherein the artificial caput femur surface comprises at least one extending portion adapted to clasp a portion of the caput and/or collum femur. The locking member comprises an element adapted to lock the artificial caput femur surface such that the caput femur remains clasped and restrained in the artificial caput femur surface.

This invention corresponds to a prosthesis for total or hip resurfacing replacement, which comprises a prosthetic femoral head made of highly cross-linked polyethylene, with a diameter ranging from 38 mm to 64 mm, to articulate with a cup or acetabular component made of metal. When the invention applies to total hip replacement, the polyethylene head includes a metal core, which contains inside the female counterpart (14) to mate with the male counterpart (13) of a Morse taper, located at the upper end of the femoral component. The use of this type of head for total hip replacement, articulated with an ultra-polished acetabular cup, reduces the risk of dislocation, transmits less angular and torque forces to the Morse taper than large metal heads, and avoids the problems related to the metal-metal bearing or with the use of large metal heads with thin polyethylene. When the invention relates to hip resurfacing replacement, the highly cross-linked polyethylene femoral head has a lower polyethylene extension or stem with or without internal metal reinforcement (151) or a metal stem integrated into a metal-back (152). Using these types of heads for hip resurfacing replacement heads eliminates the problems associated with metal-on-metal resurfacing replacements.

A system for dynamically controlling a weld profile includes a generator, and end effector, a sensor, and a computer. The generator is configured to supply energy based on the weld profile. The end effector operatively connected to the generator and configured to apply vibratory energy and pressure to an object. The sensor configured to provide an output with respect to the object. The computer configured to monitor the output and change the weld profile of the generator based on the output.

A method of absorbing a force in the hip joint of a human patient using a hip joint prosthesis, wherein the hip joint prosthesis comprises a first proximal area having a first material or part of material adapted to have a first elasticity and a second distal area comprising a second material or part of material, adapted to have a second different predetermined elasticity, such that the difference in elasticity affects the elasticity of the hip joint prosthesis along the length axis, the method comprising the step of the material of the first area of the hip joint prosthesis deforming elastically, when exposed to a force, and the material of the second area of the hip joint prosthesis deforming less elastically than the material of the first area of the hip joint prosthesis, when exposed to the force.

An apparatus for the treatment of canine or other animal hip pathologies, the apparatus (200) comprising a buffer (210) adapted to be disposed between a femur (10) and a hip socket (25), and a fixing (250) adapted to fix the buffer to the femur.
