A surgical pelvic drill for operating hip osteoarthritis adapted to create a hole in the pelvic bone of a human patient is provided. The pelvic drill is adapted to create a through-going hole placed in the acetabulum area from the abdominal side of the pelvic bone of the human patient. The pelvic drill comprises: a driving member, a bone contacting organ in connection with said driving member, an operating device adapted to operate said driving member. The bone contacting organ is adapted to create a hole in the acetabulum area starting from the abdominal side of the pelvic bone through repetitive or continuous movement. A surgical and a laparoscopic/arthroscopic method of using said pelvic drill is further provided.

Interbody cages for spinal stabilization having a frame that surrounds a central compartment suitable for retaining biological material, such as bone graft material. The central, compartment acts as a spill-free bone and biologic compartment that allows a surgeon to introduce the interbody cage into the body in an effective manner without spilling the biological material. Methods for introducing the interbody cages are disclosed.

The disclosure is directed to a resilient implant for implantation into human or animal joints to act as a cushion allowing for renewed joint motion. The implant endures variable joint forces and cyclic loads while reducing pain and improving function after injury or disease to repair, reconstruct, and regenerate joint integrity. The implant is deployed in a prepared debrided joint space, secured to at least one of the joint bones and expanded in the space, molding to surrounding structures with sufficient stability to avoid extrusion or dislocation. The implant has opposing walls that move in varied directions, and an inner space filled with suitable filler to accommodate motions which mimic or approximate normal joint motion. The implant pads the damaged joint surfaces, restores cushioning immediately and may be employed to restore cartilage to normal by delivering regenerative cells.

The present disclosure relates to a spinal fusion impactor tool that includes an attachment means for securing an implant device to the distal end of the tool, a means for adjusting the angle of the distal head relative to the handle to better position the implant for introduction into the implant site, means for remotely releasing the implant device at the distal end and a clamp device on the shaft of the tool to secure tabs, attachments and other devices. The impactor tool is preferably used in conjunction with implantation of an intervertebral fusion cage that is equipped with shims having tabs or other removing means, but may also be used to introduce, for example, an implant, graft, fusion device, wedge or distractor device into any joint space or bony region in preparation for implantation.

An implant assembly for a long bone is adapted to support an exo-prosthesis. The assembly includes a stem, a subdermal component and a percutaneous post. The stem has a proximal end that is adapted to be received in a surgically prepared medullary canal of the long bone, and a distal end having a surface that is adapted to promote bone ingrowth. The subdermal component includes a proximal portion that is adapted for attachment to the distal end of the stem, and a fixation surface that is adapted to promote soft tissue fixation. The percutaneous post has a proximal end that is adapted to be attached to the subdermal component.

A orthopaedic implant comprises an acetabular cup and a wireless communication device. The wireless communication device is coupled to a rim surface of the acetabular cup. In one embodiment, a recess is defined in the rim surface and the wireless communication device is positioned therein. In another embodiment, the wireless communication device is positioned in an annular ring formed of a biocompatible material. The annular ring is coupled to the rim surface of the acetabular cup. The wireless communication device may be, for example, a radio frequency identification (RFID) tag or device.

A medical device for implantation in a hip joint of a human patient, the natural hip joint having a ball shaped caput femur as the proximal part of the femoral bone with a convex hip joint surface towards the center of the hip joint and a bowl shaped acetabulum as part of the pelvic bone with a concave hip joint surface towards the center of the hip joint. The medical device comprising; an artificial caput femur, comprising a convex surface towards the center of the hip joint. The artificial convex caput femur is adapted to, when implanted: be fixated to the pelvic bone of the human patient, and be in movable connection with an artificial acetabulum surface fixated to the femoral bone of the patient, thereby forming a ball and socket joint. The medical device further comprises a fixation element comprising a fixation surface adapted to be in contact with the surface of the acetabulum and adapted to fixate the artificial convex caput femur to at least the acetabulum of the pelvic bone.

For a membrane encapsulated joint implant sealed under vacuum, a joint implant includes an outer cup, an inner cup, a joint head, a joint membrane, a lubricant, and an implant stem. The outer cup attached at a proximal bone. The nests within the outer cup and receives a joint head, the inner cup comprising an inner cup rim. The joint head is disposed within the inner cup and forms a bearing that rotates within the inner cup. The joint membrane sealed to the inner cup rim and vacuum seals the joint head within the inner cup to form a capsular space. The lubricant is disposed within the capsular space. The implant stem that is attached to a distal bone and that attaches through the joint head through the joint membrane.

A medical implant system is described for inhibiting infection associated with a joint prosthesis implant. An inventive system includes an implant body made of a biocompatible material which has a metal component disposed on an external surface of the implant body. A current is allowed to flow to the metal component, stimulating release of metal ions toxic to microbes, such as bacteria, protozoa, fungi, and viruses. One detailed system is completely surgically implantable in the patient such that no part of the system is external to the patient while the system is in use. In addition, externally controlled devices are provided which allow for modulation of implanted components.
