Provided are a lesser trochanter securing device and an artificial joint device. The device includes a basket portion which covers a lesser trochanter, and a buttress plating portion which is joined to a lower edge of the basket portion, extends toward a femoral shaft and is secured and joined to the femoral shaft.

A mobile electronic device comprising at least one part made of a polymer composition [composition (C), herein after] comprising at least one part made of a polymer composition [composition (C), herein after] comprising from at least one polyaryletherketone polymer [(PAEK) polymer], and at least one nitride (NI) of an element having an electronegativity (∈) of from 1.3 to 2.5, as defined in <<Handbook of Chemistry and Physics>>, CRC Press, 64.sup.th edition, pages B-65 to B-158, based on the total weight of the composition (C).

A surgical implant with recesses adapted to capture fixation medium that extravasates during implantation. The implant includes an elongated stem having a distal tip configured for insertion into an implant receiving area of a patient. A collar having recesses for capturing extravasating fixation medium is attached on the stem. The collar can be fixed to the stem by a separable collar-engagement feature or the collar can be fixed to the stem via structures on the stem.

A bone fixation clamp includes a first arcuate clamp member conforming to a shape of a bone and extending between a first connection end and a first free end, a second arcuate clamp member conforming to a shape of the bone, a second connection end of the second clamp member being pivotally attached to the first clamp member, the second clamp member extending between the second connection end and a second free end and a driving member received in the first clamp member passing out of the first clamp member to abut an abutment portion of the second member so that, as the driving member is extended further out of the first member, the driving member pivots the second clamp member relative to the first clamp member to draw the first and second free ends toward one another to apply a radially compressive force to the bone.

A medical device for delivering an action to an area of a hip joint or its surroundings, inside a human body, is provided. The hip joint of a patient comprises a collum femur and a ball shaped caput femur, being the proximal parts of the femoral bone, and an acetabulum, being a bowl shaped part of the pelvic bone. The medical device comprising; an elongated member, having a length axis along its elongated distribution, comprising a first portion, adapted to enter the body of the patient, and a mechanical element, adapted to be used during an operation in the hip joint or its surroundings, inside the body. The first portion of the elongated member comprises a holding member adapted to hold the mechanical element inside the body of the patient, wherein the first portion of the elongated member have a first portion cross-section area substantially perpendicular to the length axis of the elongated member. The first portion is adapted to pass through a hole, in a bone of the patient, the hole having a hole cross-section area. The first portion cross-section area, is adapted to be smaller than said hole cross-section area. The mechanical element have a functional status, ready to deliver said action inside said body, when held by the holding member inside the body of the patient. The mechanical element is adapted to have a mechanical element cross-sectional area substantially perpendicular to the length axis of the elongated member, substantially larger than the first portion cross-sectional area and adapted to be unable to pass through the hole, when the mechanical element is in the functional status.

Embodiments of a system and method for assessing hip arthroplasty component movement are generally described herein. A method may include receiving data from a sensor embedded in a femoral head component, the femoral head component configured to fit in an acetabular component, determining information about a magnetic field from the data, and outputting an indication of an orientation, coverage, or a force of the femoral head component relative to the acetabular component.

A package for receiving an adapter sleeve for a hip endoprosthesis, the hip endoprosthesis comprising a ball head which has to be pushed onto the adapter sleeve with a defined pushing-on force. For simplification and secure fastening of the ball head on the adapter sleeve, it is proposed according to the invention that a device for the mounting of the ball head on the adapter sleeve is integrated in the package and this device comprises indicating elements which indicate that the defined pushing-on force has been reached when the ball head is pressed onto the adapter sleeve. Preferably the package has indicating elements.

An orthopedic prosthesis for use in a hip replacement surgery includes an implantable stem component. The implantable stem component includes a core and a shell extending over the core. The shell includes a polymeric material and is configured to receive a femoral head component. Metal foam may extend over a portion of the shell.

An orthopedic prosthesis mold, comprising a first housing including a first cavity therein shaped to form a portion of an orthopedic prosthesis; a second housing coupled to the first housing, the second housing including a second cavity therein shaped to form a portion of an orthopedic prosthesis, wherein the first and second housings are constructed from a material having a first hardness; a first shell element configured to receive at least a portion of the first housing therein; a second shell element configured to receive at least a portion of the first housing therein, wherein the first and second shell elements are constructed from a material having a second hardness greater than the first hardness; and a connection element releasably engageable to the first and second shell elements to prevent separation of the first shell element from the second shell element.
