A minimally invasive surgical procedure for replacing a hip joint is provided. A main incision is initiated at a point being a projection of a tip of a greater trochanter and extends proximally about a distance in the range of from 1 cm to 8 cm in line with the femoral axis. An inline capsulotomy is performed, while keeping muscles and posterior capsule intact, to expose the hip joint capsule for accessing the hip joint. The femoral canal is prepared for receipt of a femoral implant. The femoral head is resected and removed out of the acetabulum. A step of acetabular preparation is performed using a retractor comprising two tip rails, each tip rail having a plurality of tines. Related tools, devices, systems and methods are also provided.

Surgical tools which are used to separate from one another a femoral cup and an acetabular ball in an implanted hip replacement prosthesis. At its distal end, elements of the surgical tool engage the femoral cup and the acetabular cup. When proximal handles of the tool are squeezed toward one another, the engagement elements move away from one another. Thus, a surgeon is able to separate the femoral cup and the accetabular ball from one another without pulling the acetabular cup away from the acetabulum or the femoral cup and/or femoral implant away from the femur, thereby accomplishing the separation without disrupting any bone ingrowth.

A surgical tool for extracting an acetabular ball from an acetabular cup in an implanted hip prosthesis wherein the from acetabular ball is affixed by means of a Morse taper to a stem extending from bottom of the concave portion of the acetabular cup. The surgical tool enables a surgeon to remove the ball without pulling on the acetabular cup and without disrupting any bone ingrowth because the tool maintains pressure on the cup while exerting an opposing pressure pulling on the ball.

The disclosure includes methods and systems for making orthopedic connections where there is unique adjustability to the connection. Illustratively, one embodiment provides a connecting assembly for connecting a plurality of orthopedic components. Such connecting assemblies can include a first orthopedic component that provides a female bore. Additionally the assembly can include a second orthopedic component that can be or include a male-type connecting member that is positionable in the bore of the first orthopedic component. In one preferred form, the male-type connecting member will be a quasi-spherical member. The quasi-spherical member can include a textured outer surface, e.g., for contacting one or more walls or surfaces in the bore in a fashion that removeably locks or helps to removeably lock or fix the quasi-spherical member in the bore.

A medical implant extractor including a handle, a shank extending from the handle, and a laterally projecting tip at a distal end of the shank. The disclosure further provides a kit including the aforementioned medical implant extractor and a striking tool for striking the medical implant extractor.

The glenoid implant comprises a baseplate, an articular component which has a convex articular surface, and a platform which is provided both to be secured to the articular component by a first attachment and to be secured to the baseplate by a second attachment, the first attachment being independent from the second attachment and defining an assembly axis along which the platform and the articular component are assembled together. The first attachment comprises both a translational connection that is intraoperatively operable to prevent translation between the platform and the articular component along the assembly axis, and a rotational connection that is intraoperatively operable to prevent rotation between the platform and the articular component around the assembly axis, the translational connection and the rotational connection being distinct from each other. The glenoid implant allows assembling the platform indifferently with one of various articular components which differ from each other for example by their material composition and/or by some geometric features of their convex articular surface and/or etc. The articular component that is effectively assembled with the platform can be chosen by the surgeon during surgery, i.e. during an implantation operation or just before the latter.

A system for converting a first joint prosthesis to a second joint prosthesis in-situ includes a plurality of inserts having a bone interface side and a component facing side and a plurality of articulating components having a cavity configured to receive at least one of the plurality of inserts. The plurality of inserts may be unicompartmental, bicompartmental, or tricompartmental. The inserts may be made of metal and may have a bone contacting surface made of a porous metal. The plurality of articulating components may be unicompartmental, bicompartmental, or tricompartmental. The articulating components may be sized and shaped to cover one or more of the plurality of bone interface components and span a distance therebetween. The articulating components may be made of a polymer.

A fitting ring can be provided that is attachable to an edge of a liner for an acetabular shell. The fitting ring can include an alignment portion shaped or configured to engage a lip portion of the acetabular shell as the liner is inserted into the acetabular shell to center the liner and correct any pivoting of the liner relative to the acetabular shell. A driving force can be applied to the liner to drive the liner into the acetabular shell while the fitting ring guides the liner as the liner is inserted into the acetabular shell. Driving the liner into the acetabular shell can also cause the fitting ring to disengage from the liner.
