MEGASYSTEM-C
Modular
A high degree of intraoperative flexibility provided by modular combination options for individual, finely graduated treatment of major bone defects
Compatible
For specific solutions based on experience and compatibility with successful LINK revision implants
Proven
In terms of material, stability, and many years of clinical use
The modular MEGASYSTEM-C was developed in collaboration with Prof. Dr. Capanna and other experienced orthopedic surgeons. The many and varied treatment options permit both partial bone replacement in the proximal and distal femur region with very small gradations, and also total femur replacement and long tibia replacement.
For intraoperative flexibility, the MEGASYSTEM-C is based on the Endo-Model SL Knee Implant, the secure modular connections, and the flexible choice of anteversion, leg and neck length by employing the connection principle of the MP Reconstruction Prosthesis.
The best possible prospects for the surgical outcome are created by incorporating biomechanical loading and anchoring principles plus many years of experience gained from the use of proven implant components.
The advantages for you
You extend the Endo-Model SL (and also Endo-Model W) and use MP Neck Segments.
Intraoperative choice between partial and total femur replacement. According to individual patient requirements, the surgeon is free to choose, during the course of the surgery, either to implant
- a push-through stem to preserve the diaphyseal femoral bone or
- to move up to total femur replacement by using stem segments.
This is made possible by the compatibility with two constrained knee systems (Endo-Model SL and Endo-ModelW). These prostheses can be combined with the proximal hip components of the MP Reconstruction Prosthesis.
Proximal femur replacement and tibia replacement
- Solid neck segments are available, including trial prostheses, with holes for fixation of the surrounding muscles and ligaments
- Proximal tibia replacement with integral patella clamp and drill holes for attaching the soft tissues
- 10 mm build-up steps for leg length reconstruction
- Use of the assembly instruments
- Intelligently designed tapered connections
- Securing the taper connection with the fixation screw
LinkSpacer
Hip spacer
The hip spacer made of PMMA bone cement contains a highly concentrated antibiotic (gentamicin).
An internal metal core of stainless steel (AISI 316L) reinforces the temporary prosthesis.
Advantages
- Metal core gives high strength with limited physiological and mechanical loading.
- Prevents proximal femur migration and facilitates the surgical approach during the final revision.
- Helps to maintain the functionality of the hip muscles.
- Early mobilization means early rehabilitation for patients.
Knee spacer
The knee spacer is made from antibiotic-containing (gentamicin) PMMA bone cement.
Advantages
- Preservation of the intra-articular space.
- Retention of joint movement. Facilitates surgical access because the patellar tendon is free of the adhesions usually associated with immobilization.
- Allows the extensors to be conserved and ligament function to be maintained.
- Can preserve the function of the collateral ligaments.
- Better scope of mobilization than with block spacers.
- Reduces the functional recovery time after final revision procedure.
Endo-Model Knee Fusion Nail
Right/left version
Made of CoCrMo or LINK® PorEx®*
Femoral and tibial components
With polyethylene centralizers
With two securing screws, including UHMWPE stopper
- High degree of flexibility provided by modular stem components and stem lengths of 60 mm to 280 mm from the Endo-Model Rotational and Hinge Knee System
- Longitudinal ribs for rotational stability
- Three flat sections for rotational stability in the bone cement
- Secure connection: oblique contact surfaces provide tapered locking of the coupling
- 5° flexion
*Only available custom-made on request.
The LINK Endo-Model Knee Fusion Nail is placed like a coupled knee prosthesis with stem. In the event of infection, targeted topical antibiotic treatment is achieved via the cementing. The Knee Fusion Nail comprises of a femoral and a tibial component. The two components are stably connected by a special coupling. In the modular version, it can be combined with both cemented and cementless modular stems.
The stems of the cemented version are tapered, but have three flat planes for anti-rotation securing in the cement bed. The implant components are given an anatomical curvature of 5° flexion immediately after coupling. Centralizers ensure correct intramedullary positioning at each end of the nail.
Wide choice of modular stems available. Following the failure of a knee prosthesis and/or osteosynthesis with loss of function of the extensors, arthrodesis may be the only surgical option for stabilizing the joint. Implantation of a LINK Endo-Model Knee Fusion Nail enables fast and loadable mobilization of the patient. Loss of leg length can also be limited in this way.
