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 acetabular 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.

Surgical trays and tools for use in hip revision surgery wherein the implanted prosthesis is a reverse prosthesis comprising an acetabular ball and a femoral cup. A set of trays is provided having tools for i) separating a femoral cup from an acetabular ball, ii) separating a femoral cup from a femoral implant and iii) separating an acetabular ball from an acetabular cup. A tool for removing an acetabular cup from an acetabulum is also described. A surgical method is also provided wherein the acetabular ball and femoral cup are separated first followed by, in any order, separating the femoral cup from the femoral implant and separating the acetabular ball from the acetabular cup.

A modular acetabular cup assembly for use with multiple bearing liners is disclosed. The acetabular cup assembly includes a shell having a tapered inner wall and two circumferential grooves. The shell may be used with polyethylene, ceramic, metal, and other types of liners.

Joint prosthesis (100) with removal device comprising a first portion (10) suitable to be implanted in a bone structure and suitable to couple with a second portion (50), characterised in that said second portion (50) houses within it a removal element (70) suitable to interact with at least one of said first and second portions (10, 50) and in that said removal element (70), is configured to be operated in translation with respect to the second portion (50), and to generate a detachment force such as to uncouple the first portion (10) from the second portion (50) of the joint prosthesis (100).

An articular component is provided that includes an articular body having an articular surface, a bone anchor, a coupling portion, and a coupler. The bone anchor includes a distal end configured to be lodged in a bone and a proximal face. The coupling portion includes a recessed area in the articular body disposed between the articular surface and the distal end of the bone anchor. The coupler includes a first portion configured to mate with the coupling portion at a selected rotational position, and a second portion opposite the first portion, wherein the second portion is configured to couple, directly or indirectly, the articular body with the bone anchor.

A surgical tool for separating two components, for example removing a femoral head from a femoral stem, having a four bar chain whose four bars are a first handle (L1), an crossover component (L2), a second handle (L3) and a crossbar (L4) pivotally connected respectively by: a first joint (J1) between the first handle and the crossover component; a second, crossover joint (J2) between the crossover component and the second handle; a third joint (J3) between the second handle and the crossbar, and a fourth joint (J4) between the crossbar and the first handle, and wherein, upon application of a gripping force to the first and second handles, the first and second jaws separate from one another so as to separate the two components engaged therewith.
