    摘要: A biological tissue rootage face (30) capable of closely bonding to a biological tissue (H, S) is composed of a biocompatible material and has numerous fingertip-shaped microvilli (41). The microvilli (41) have tip diameters in the order of nanometers. An implant (1) has the biological tissue rootage face (30) on a surface (11, 24) configured to root into a biological tissue (H, S). In a method for forming the biological tissue rootage face (30), a surface of a biocompatible material is subjected to laser nonthermal processing carried out by emitting a laser beam in air, to form numerous fingertip-shaped microvilli (41). The laser beam is a laser beam of an ultrashort pulse laser.

    摘要: Orthopedic systems and methods are provided for use in preparing joints for implants. Specifically, hip preparation systems and methods are disclosed which can include a surgical orientation device. The hip preparation systems and methods can be used, for example, to orient the hip during the procedure, determine the orientation of an anatomical plane or planes, and orient a prosthetic component or components.

    摘要: Various embodiments disclosed relate to a method for producing an implant model and associated systems. The method can include receiving patient specific data, producing a preliminary implant model based on the received patient specific data, running a simulation on the preliminary implant model to produce a revised implant model with a range of motion zone using the patient specific kinematics, optimizing the preliminary implant model with a dynamic simulation to determine a cup anteversion angle, analyzing the revised implant model for spino-pelvic risk, and outputting the implant model.

    摘要: A package (2; 3) for an object is provided having a bottom shell (21; 31); a top shell (22; 32) having a closure portion (24; 34) referred to as a “cap”, and a connection portion (23; 33) in the form of a hollow body and connected to the closure portion (24) by a hinge (25) to enable the closure portion (24; 34) to tilt relative to the connection portion (23; 33) in order to release access to the inside of the bottom shell (21; 31) through the connection portion (23; 33). The connection portion (23; 33) is provided with a stiffener element (290; 390) and a sealing strip (4; 4′) connects together the edges (241, 231) of the cap (24; 34) and of the connection portion (23; 33) that face each other over the entire length of said edges. Said connection portion (23; 33) of the top shell (22; 32) and of the bottom shell (21; 31) are two parts that are fastened to each other, preferably by bonding.

    摘要: The invention relates to a prosthesis for implantation into a living body in the form of a magnetic artificial joint, in particular an artificial shoulder joint, comprising: a) a first prosthesis member comprising a socket member, b) a second prosthesis member comprising a head member, c) one of the socket member and the head member is at least partially composed as a permanent magnet and the other one of the socket member and the head member is at least partially composed of a magnetic material, or the socket member and the head member are both at least partially composed as a permanent magnet, d) the socket member comprises a recess on a surface side to be coupled with the head member, the recess comprising a concavely contoured contact surface, e) the head member comprises a projection on a surface side to be coupled with the socket member, the projection comprising a convexly contoured contact surface, f) the convexly contoured contact surface is adapted to the concavely contoured contact surface, such that the head member can be coupled in a rotatably jointed manner to the socket member in the nature of a ball/ball-socket joint, g) wherein the convexly contoured contact surface can perform a generally slip-fee rolling motion or a combined slipping and rolling motion on the concavely contoured contact surface in reaction to a change of an angle between the first and the second prosthesis member, and the convexly contoured contact surface can be shifted across the concavely contoured contact surface within a shifting area.

    摘要: A hip implant comprises an acetabular cup to be inserted into an acetabulum of a pelvis, together with a femoral head and neck portion and a main body shaft to be inserted into the femoral neck and proximal femoral shaft. The femoral head and acetabular cup form a smooth spherical-surface joint. The femoral head on a femoral head base is attached to a femoral neck rod, which has a tapered end that engages in a hole through the main body shaft, i.e. the main body shaft has a diagonal hole therethrough located at the center line of the neck of the femur to receive the tapered end at a specified angle that aligns with center line of the neck. A secured lock mechanism, insertable into the main body shaft above the diagonal hole, can be screwed down to compressively engage the tapered end of the femoral neck rod. The diagonal hole (and matching tapered end of the femoral neck) can have an overlapping two-circle cross-section, can have a specified taper angle, and a choice of incline to match a patient's femoral angle between the neck and shaft. The tapered neck rod can have wedge-shaped locking surface features to provide even more stability.

    摘要: A method of implanting a hip joint prosthesis into a patient can include obtaining image data of hip joint anatomy of the patient. Physical activities that the patient desires to participate in subsequent to implanting the hip prosthesis can be determined. A size and an initial placement of the hip joint prosthesis based on the image data can be determined. A desired range of motion of the hip joint prosthesis based on the determined physical activities can be determined. A plan can be created comprising a desired implanted location of the hip joint prosthesis and based on the desired range of motion. The plan can be incorporated onto a guide. The plan can be executed with the guide thereby implanting the hip joint prosthesis into the patient at the desired implanted position.
