Joint Care Reconstruction

Step 1: wound cleaning and debridement

Wound cleaning is considered a primary factor in modern cementing technique to prepare the bone bed before implantation and to improve survival of the implant.

Using Pulse Lavage for wound cleaning and preparation has been proven highly effective in achieving good cement fixation and penetration into the cancellous bone. Pulse Lavage efficiently removes blood and debris, prevents circulatory reactions when inserting the prosthesis, and also reduces the risk of fat embolism.

Step 2: cement pressurisation

Cement restrictors are used to maintain appropriate filling and pressurisation of bone cement, and prevent implant loosening.

VarioPlug provides the right pressure across the femur and ensures effective integration of cements with bone: both distally and proximally. As a result, VarioPlug avoids intramedullary cement leakage or plug migration during cement and stem insertion, and ensures adequate intramedullary pressure during implantation surgeries.

Step 3: using the right bone cement

Bone cement, unloaded or antibiotic-loaded, allows a surgeon to affix prosthetic joint components in patients with compromised bone strength due to osteoporosis.

Choosing the right bone cement is, therefore, crucial to establish a secure implantation and prevent implant loosening. C-ment NXT bone cement offers adaptable handling the time, which provides the surgeon ease of use and flexibility when managing and applying bone cement, allowing for a strong interface between bone, cement, and implant. .

Leader Biomedical’s hip systems combines proven and time-tested designs with the latest in bearing and coating technologies and include systems for both total hip replacements and revisions for hip fractures.

Our VarioNXT® is a total hip replacement system for press-fit fixation. This system is composed of the Expersus Pressfit stem, Primaro Cup, and Primaro Cup Inlay. Both the Expersus Pressfit Stem and Primaro Cup are covered in a Titanium plasma spray and calcium phosphate coating, promoting rapid bone ongrowth and ingrowth for optimal fixation.

The VarioClassic™ cemented hip system is composed of the Müller Straight Stem and Müller Cup. This implant type has been used for hip endoprosthesis for decades and is one of the most commonly used cemented implants worldwide. The versatility of the Müller Straight Stem also allows for treatment of Hip Fractures when combined with our bipolar head.

Leader Biomedical Joint Care Reconstruction portfolio further offers a variety of metal and ceramic femoral heads that can be combined with our stems to create an ideal and personalised solution for patients.
