An intramedullary femoral broach aligns two instruments. A femoral neck resector guide slides over the broach and centers on the patient's femoral head to determine the height and angular rotation of resection. A circular ring of the head and cutting arms assure the system will fit any femur. A template is applied to the femoral broach and seats itself against the buttress of the broach locking it into place. The broach is then reinserted into the intramedullary canal. When the template reaches the greater trochanter the sizer is adjusted to the rotational anteversion of the canal. The handle of the femoral broach is struck with a mallet until the template is imbedded into the proximal femoral neck intramedullary bone. A retractor facilitates reaming of the acetabulum through a small anterior incision. A proximal portion digs into the bone of the superior acetabulum to allow for retraction of soft tissues.

Disclosed is a method and apparatus for repairing the femur. A connector is provided having a claw-like member to engage with the greater trochanter. Along the body of the connector are a plurality of cable apertures and cable screws to receive and engage with cables that loop around the femur. Along the inferior end of the connector are bone screw slots and bone screws engaging the connector with the femur. The bone screws provide added support to the re-attached greater trochanter and provide support for periprosthetic fractures. The connector may be used to re-attach the greater trochanter by impacting a connector onto the greater trochanter, positioning the greater trochanter onto the femur, passing cables around the femur and through the connector, tensioning the cables to provide engagement between the greater trochanter and the femur, and attaching the connector to the femur using at least one bone screw.

A bone fixation system has an elongate portion (122; 299) for engaging over a long bone (e.g. a femur) and an end engagement portion (120; 260) for engaging over an end region of a long bone (e.g. a greater trochanter). To allow for variation in bone geometries, the two portions are pivotably connectable. Preferably the connection is lockable. Thus the system can be adapted to a particular bone geometry and then made rigid.

A support contour of a cushion, such as a wheelchair cushion, defines relief areas at locations adjacent to skin covering the ischial tuberosities, the greater trochanters and the coccyx and sacrum of a person sitting on the support contour. Support areas of the support contour transfer force into the pelvic area adjacent to skin covering tissue masses on opposite lateral sides of the posterior buttocks and beneath the proximal thighs of the person. Greater clearance is also provided in the perineal area. Risks of pressure ulcers from pressure and shear forces on bony prominences is reduced while providing support at the broader areas without bony prominences in such a manner to encourage postural alignment. The risks of skin breakdown perineal are diminished.

An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps. After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur. After preparation of the femoral cavity, a femoral implant in accordance with the present invention is inserted into the aforementioned cavity in the femur. The femoral implant is thereafter secured in the femur, with portions of the implant extending into and being secured within the femoral head and portions of the implant extending into and being secured within the femoral shaft.

According to one embodiment, a method comprising providing an incision locator comprising a first wing and a second wing, the first wing adapted to be oriented generally along the femoral axis of a femur forming the hip on which the surgery is being conducted, positioning a proximal portion of the first wing adjacent to the greater trochanter, positioning other portions of first wing generally parallel to the femoral axis, indicating a proper placement of an incision based at least in part on the position of the second wing of the incision locator, performing an incision using at least one incision guide in at least one of the first and second wings, and completing the surgical procedure is described.

A bone plating system comprising: a plate, where the plate is low-profile and capable of contouring to a bone; a variable number of screw holes, locking or non-locking; at least one channel or tunnel through the plate; and at least one flexible device passing through the channel or tunnel and passing through soft tissue attached to the bone. The low profile plate, in combination with the flexible device passing through the surrounding soft tissue, functions as a tension band and acts to neutralize the muscle forces tending to pull the bone apart at a fracture. The low profile tension band plating system is targeted for periarticular tensile fractures for repair of patella, olecranon, greater trochanter, greater tuberosity, radial styloid, lateral or medial malleoli, or lateral malleolus.

A femoral stem 2 for artificial hip joint is provided that is capable of tightly fixing a greater trochanter and is suitable for treatment of transcervical fracture where it is necessary to fix the greater trochanter. The femoral stem 2 comprising: a stem member 20 including a distal part 21 of the stem member which is inserted in a medullary cavity of a femur and fixed therein and a proximal part 22 of the stem member which has a neck 26 for fixing an artificial head and is positioned at a proximal end of the distal part, the distal part and the proximal part being integrated or separable; a plate fixing portion 36 which is detachably attached at a top of the proximal part; and a greater trochanter plate 3 for depressing the greater trochanter 71, the greater trochanter being fixed to the plate fixing portion 36 at a certain angle or fixed to the plate fixing portion so as to adjust an angle. Since the greater trochanter plate 3 is fixed onto the femoral stem 2 of the present invention, the greater trochanter is tightly fixing and thus the fixation can be stabilized. Furthermore, since the greater trochanter plate 3 is fixed at the top of the proximal part 22, the greater trochanter plate 3 covers the top of the greater trochanter 71 when the greater trochanter 71 is fixed. Therefore upward displacement of the greater trochanter by a gluteus medius musculus can be effectively suppressed.
