The present invention relates to a system and method for sacral and trochanteric support and off-loading. The system provides a ultra low pressure plenum and a positioner. The patient body size and size and corresponding surface area of the positioner control the amount of gas which is displaced evenly against the walls of the ultra low pressure plenum to allow the combination of the ultra low pressure plenum and the positioner to slightly lift a patient from a bed surface, thereby offloading the sacrum and trochanter. The positioner can be an ultra low pressure bladder.

A stem of an artificial hip joint is capable of removing a gap that may be formed between a proximal portion of a femur and a backside of the stem. The stem has an upper end portion to face a proximal side and a backside to face a greater trochanter and is adapted for insertion into, and fixation to, a medullary space of a femur. The stem has a through bore opened both to the upper end portion and the vicinity of proximal end of the backside.

The invention relates to a device for bone fixation, comprising A) an intramedullary pin (1) having a longitudinal axis (17), a distal tip (2) for introduction into the marrow cavity, and a proximal rear end (3) and B) a bone plate (10), for location on the greater trochanter, arranged at the proximal rear end (3) of the pin (1), whereby C) the pin (1) has a through transverse drilling (6) in the proximal half (7) thereof which faces the proximal rear end (3), for housing a hip screw (30) and D) the bone plate (10) terminates proximally above the transverse drilling (6).

The invention relates to an implant for refixation of the greater trochanter (9) on which an osteotomy has been performed or which is fractured. The implant comprises a plate (1) that can be fixed on The invention relates to an implant for refixation of the greater trochanter (9) on which an osteotomy has been performed or which is fractured. The implant comprises a plate (1) that can be fixed onthe proximal femur, and a device (20) that can hold the greater trochanter (9) with a form fit or force fit on the femur (2). This holding device (20) preferably has bendable prongs (16, 17) located athe proximal femur, and a device (20) that can hold the greater trochanter (9) with a form fit or force fit on the femur (2). This holding device (20) preferably has bendable prongs (16, 17) located at a distance from each other, the first end portion of these prongs (16, 17) being attached to the upper edge (37) of the base plate (1). The holding device (20) also has flexible, elongate members (2t a distance from each other, the first end portion of these prongs (16, 17) being attached to the upper edge (37) of the base plate (1). The holding device (20) also has flexible, elongate members (21, 22), each of which is attached at one end to the free end portion (19) of the respective prong (16, 17). The other, free end portions (142) of the longitudinal members (21, 22) are secured laterall1, 22), each of which is attached at one end to the free end portion (19) of the respective prong (16, 17). The other, free end portions (142) of the longitudinal members (21, 22) are secured laterally on the base plate (1) after these longitudinal members (21, 22) have crossed the medial aspect of the greater trochanter. This results in a tensioning band construction with at least two restraintsy on the base plate (1) after these longitudinal members (21, 22) have crossed the medial aspect of the greater trochanter. This results in a tensioning band construction with at least two restraintsbased on a plate fixed securely on the proximal lateral femur.based on a plate fixed securely on the proximal lateral femur.

A femoral stem including a stem member having a distal part of the stem member which is inserted in a medullary cavity of a femur and fixed therein and a proximal part of the stem member which has a neck for fixing an artificial head and is positioned at a proximal end of the distal part. The distal part and the proximal part are integrated or separable. Also, a plate fixing portion is detachably attached at a top of the proximal part, and a greater trochanter plate is provided for depressing the greater trochanter. The greater trochanter is fixed to the plate fixing portion at a certain angle or is fixed to the plate fixing portion so as to adjust an angle of the trochanter plate.

Protective devices, to protect a body part having a bony portion with a soft tissue layer between the bony portion and an outer skin layer, have an inner surface which conforms to the body part to be protected and are applied to the body part to reduce pressure exhibited at the interface between the bony portion and the soft tissue layer, across the soft tissue and outer skin layers and at the interface between the outer skin layer and a support surface. The protective devices may be made of any material suitable for distributing the weight of the body part over an extended area and volume and may include a mushy material, a hard shell, a hydro absorptive material, and a wound dressing with medication. The body-part to be protected includes at least one of the heel, trochanter, knee, sacrum, coccyx, ischium, scapula, elbow, ankle, buttocks and occiput; The protective devices may be secured to the body part directly or via a garment or any other suitable securing means.

A device for preventing a hip fracture includes: a shaft having a first end and a second end and an expanding means for engaging the femoral head at the first end. The shaft is positioned in a hole of a predetermined depth in a femur. The hole extends from the greater trochanter to the femoral head of the femur, such that the first end is positioned in the femoral head and the second end is positioned in the greater trochanter. The device is oriented substantially perpendicular to the long axis of the femoral shaft.

A curved positioning and insertion instrument for inserting a guide wire into the femur has a curved guide tube with a distal end to be placed on the trochanter and / or the medial muscle and a proximal end for inserting a guide wire. The instrument also has a holding arm that links the guide tube to a handle. A positioning hook fitted with at least one correction bore for receiving the guide wire or another guide wire is arranged at the distal end of the guide tube. This structure makes it possible to easily insert further or additional guide wires relative to a reference guide wire.
