The present invention relates to a method of treating a hip joint of a human patient, the hip joint comprising an acetabulum, the acetabulum being a part of the pelvic bone, and a caput femur, the caput femur being the proximal part of the femoral bone, said method comprising the steps of: cutting the skin of the human patient, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in said dissected area, said hole passing through the pelvic bone and into the hip joint of the human patient, and performing an action in the hip joint, through said hole in the pelvic bone.

An implant assembly including an expandable vertebral body replacement implant. Two outer cores disposed on opposing ends of an inner are configured to move away from each other when the inner core is actuated. The implant assembly may include removable endplate configured to engage vertebral bodies as interbody spacer or through a corpectomy. The implant may include a locking mechanism to prevent collapse or movement the implant assembly after implantation. The locking mechanism may be automatically engage after removal of an inserter instrument from the implant assembly.

A method of treating a hip joint of a human patient using a pelvic drill comprising a driving member, a bone contacting and an operating device for operating said driving member. The method comprise the steps of creating a hole passing through the pelvic bone and into the hip joint of the human patient, and providing at least one hip joint surface to the hip joint, through said hole in the pelvic bone of the human patient. In one embodiment the method includes inserting a needle or tube like instrument into the patient's body for filling a part of the patient's body with gas and thereby expanding a cavity within the body.

An implant assembly including an expandable vertebral body replacement implant. The implant assembly includes a right hand end and a left hand end configured to attach to a threaded actuator. An outer ring is configured to surround each of the right and left hand ends and the threaded actuator. The implant assembly may include removable endplates configured to engage vertebral bodies as interbody spacer or through a corpectomy. The implant assembly includes a locking mechanism to prevent collapse or movement the implant assembly after implantation. The locking mechanism automatically engage after removal of an inserter instrument from the implant assembly.

A method of treating a hip joint of a human is provided. The method comprises a step of dissecting an area of the pelvic bone, comprising at least one of the following: dissecting an area between peritoneum and the pelvic bone, dissecting an area between the pelvic bone and the surrounding tissue, dissecting an area of the pelvic region, and dissecting an area of the inguinal region, or, the method comprises at least two of the following steps: dissecting an area of the abdominal cavity, penetrating the hip joint capsule, dissecting an area between peritoneum and the pelvic bone, dissecting an area of the pelvic bone which comprises: dissecting an area between the pelvic bone and the surrounding tissue, or dissecting an area of the pelvic region, or dissecting an area of the inguinal region, and removing or penetrating the tissue surrounding the pelvic bone in the area opposite to acetabulum.

A method of treating a hip joint of a human patient by providing said the medical device is provided. The hip joint comprising a caput femur and an acetabulum, the method comprises the steps of: cutting the skin of the patient, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in said dissected area, said hole passing through said pelvic bone and into the hip joint of the patient, and providing said medical device to the hip joint, through said hole in the pelvic bone of the patient.

Spinal spacing implants, spinal spacer assembly, expander and insertion instruments, kits and methods of assembly and use are disclosed. The spinal implant replacement instrument kit including a distraction instrument, a spacer inserter, and a spinal implant. A distraction instrument includes a first inserter member, a second inserter member, a first arm coupled to the first inserter member, a second arm coupled to the second inserter member, a distraction system coupled to the first arm and second arm, a first handle coupled to the first arm and the distraction system, and a second handle coupled to the second arm and the distraction system. Spinal spacing implants, spinal spacer assemblies, and methods of assembling and using the implants assemblies, and instruments are also disclosed.

The present invention involves a system and methods for assembling and implanting a vertebral body implant. The vertebral body implant includes, but is not necessarily limited to, an expandable core body and endplates that can be attached at both ends. End plates of various shapes, sizes and angles are attachable to the expandable core in a plurality of positions so that a suitable vertebral body implant can be implanted between vertebrae from an anterior, anterior-lateral, lateral, posterior or posterior-lateral approach.

The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.
