Embodiment Construction

[0031] With reference to the accompanying drawings, reference numeral 1 generally designates a spacer device according to the invention for the treatment of infection at the elbow joint, in particular during removal of the first prosthesis and implantation of the second prosthesis, during the treatment of the infection A temporary spacer device used during two-stage therapy to treat an ongoing infection at the implant site.

[0032] The spacer device 1 is able to maintain the joint space and ensure the articulation of the elbow until the implantation of the new prosthesis, while the spacer device 1 is able to maintain the joint space due to the presence of suitable drugs or agents such as one or more antibiotics in the spacer device itself. And the infection is treated by means of contact of the device with the entire infected area to be treated.

[0033] The spacer device 1 according to the invention is made of a biocompatible material to which is added and / or can be added wi...

Abstract

The present invention regards an elbow spacer device, comprising: at least one ulnar section (2), comprising a stem portion (6) extended along a substantially longitudinal axis (x-x) between a proximal end (7) and a distal end (8); at least one humeral section (3), comprising a stem portion (9) extended along a substantially longitudinal axis (y- y) between a proximal end (10) and a distal end (11), the distal end (11) of the humeral section (3) delimiting an engagement seat (4) with the proximal end (7) of the ulnar section (2); articulation means (5) between the distal end (11) of the humeral section (3) and the proximal end (7) of the ulnar section (2), positionable along an axis (z-z) that is orthogonal to the substantially longitudinal axis (y-y) of the humeral section (3). The proximal end (7) of the ulnar section (2) is engageable in the housing seat (4) with its own longitudinal axis (x-x) not orthogonal to the axis (z-z) of the articulation means (5), according to at least two opposed working positions, according to whether the spacer device is intended to be implanted in the right or left upper limb of a patient.

Description

technical field [0001] The invention relates to a spacer device for the elbow joint, which can in particular be used in the treatment of infections according to a so-called "two-stage" treatment. Background technique [0002] Although the elbow is often thought of as a single joint, the elbow includes three separate joints associated with a single capsule. These joints are the humeroradial joint, which allows flexion and extension of the forearm on the arm, and the proximal radioulnar joint, which allows pronation and supination of the hand. [0003] The present invention relates to spacer devices acting on the humeroulnar joint. [0004] During the treatment of an elbow injury that requires a prosthesis, the tissue around the prosthesis may become infected. [0005] Therefore, implantation of a prosthesis is necessary to treat the infection, and once the infected tissue has healed, a new permanent prosthesis must be implanted. [0006] This approach to treating infection...
