Hipokrat 2000 CR Diz Protezi

Hipokrat 2000 CR Diz Protezi

Tasarım
Fleksiyonda stabilite sağlamak için sağlam bir arka çapraz bağa dayanan minimal kısıtlanmış protez

Endikasyonlar
• Minimum kemik kaybı, yumuşak doku gevşekliği ve sağlam bir arka çapraz bağ olan artrit durumu
• Varus deformitesi <10 derece – valgus deformitesi <15 derece

Radyografiler
Bağkesen tipi diz protezlerde olduğu gibi radyografiler femoral bileşenin orta kısmında kutu göstermez

Avantajlar
• Ps dizlerde meydana gelebilecek post-cam sonrası çıkma veya sıkışmayı önler.
• Normal diz kinematiğine daha çok benziyor
• PS dizdekinden daha az kemik kesilmesi gerekir
• Doğal PCL’nin korunmasıyla geliştirilmiş propriyosepsiyon
• PCL yetersizliği durumlarında fonksiyonlarda kayıp olmaksızın anterior stabilize veya ultra uyumlu şekiller yoluyla PCL ikamesine izin verebilir.

Dezavantajlar
• Sıkı PCL, polietilenin hızlı bir şekilde aşınmasına neden olabilir.
• Gevşek veya yırtılmış PCL fleksiyon dengesizliğine ve subluksasyona neden olabilir

The femoral implant compresing of 3 sliding surfaces in contact with polyethelene, is a Cr.Co alloy who’s reliability needs no further proof. The patellar groove is deeply hollowed and presents an anatomically aligned outline. This feature serves for better patellar guidance and relief of strain on the knee extensor apparatus. The femoral component is available in a cemented and a non-cemented version. A posterior stabilised version for more stabilisation is also available.

• Anatomical 9 sizes femoral compenent offers optimal fit
• MRI safe Conditional option
• Cr.Co.Mo. alloy
• Rough inner surface provides strong cementation
• Cemented and Uncemented options
• Anatomic patellofemoral track
• Deep patella groove provides stable pattelofemoral tracking
• 7 degree anterior flange

The tibial insert of ‘‘HİPOKRAT 2000 knee prosthesis’’ is an polyethelene high density. This choice is motivated by the excelent mechanical properties of this materials both in its strength and its tribological (low friction) qualities. This High density materials, proved for many years in the most reliable hip and knee prostheses, stil being unequalled today. It is here meticulously machined on specific dedicated machining centres, eliminating all risks of contamination. The tibial insert is available in 6 different heights of 6, 8, 10, 12, 15 and 18 mm so that the joint height can be restored depending on the degree of tibial bone substance loss. An ultracongruent and a posterior stabilised version for more stabilisation are also available.

• Higher anterior surface will prevent the paradoxial anterior sliding
• Captured attachment screw
• 5 Sizes, 6 thicknesses (6, 8, 10, 12, 15 and 18 mm)
• Anatomic radius
• UHMWPE pollyethelene

The tibial plate has been designed in Cr.Co.Mo., and have rough inner surface to provides strong cementation. A locking screw which completely locks the tibial insert and ensures positive anchorage (without the slightest risk of the system being ejected). We add a final security. This locking screw is itself fitted with a locking mechanism.

• 9 sizes offers optimal fit
• MRI safe Conditional option
• Cr.Co.Mo. alloy
• Improved locking mechanism design
• Wings growing according to the size to ensure better stability.

The patella is an polyethelene with offers the most ceratin contact and friction behaviour with the Cr.Co. trocchlea. Patellar implant is designed to help fill in lost patellar bone, restoring the patellofemoral joint space to its normal height.

• Smooth anatomical design
• UHMWPE pollyethelene
• 5 different diameter (31, 33, 35, 37 and 39 mm)
• Choice of one-peg and three-peg fixation modes are avaliable for increased flexibility
