Elbow endoprosthetics

ICARA®  Radial Head System

The completely innovative concept of the ICARA® radial head system allows for intraoperative adjustment and fine-tuning of the prosthesis preload. The three-part, modular head component can be adjusted intraoperatively to the required neck length for restoring joint tension and stability. This adjustment is continuously variable.

Indications

  • Degenerative joint diseases (e.g. osteoarthritis, avascular necrosis)
  • Post-traumatic osteoarthritis
  • Fractures
  • Rheumatoid arthritis
  • Revision of prostheses with bone defects (Paprosky Type 3a/3b)
  • Bone reconstruction with transplants possible
  • Replacement of non-load-bearing bone segments
  • Tumor-related resections
  • Massive bone loss (e.g. Morbus Gorham, revisions)
  • Endoprosthetic treatment of fractures, pseudarthroses

Key Features

  • Distalization of the rotation center
    stable fixation by shifting the torque of the prosthesis to the level of the radial tuberosity
  • Various stem options Cemented and cementless stems with variable collar heights to prevent stem subsidence.
  • Continuous length adjustment
    avoidance of overstuffing or gapping: the neck length is adjustable by 4mm.
  • Multidirectional self-adjustment
    minimization of force peaks on the capitulum of the humerus due to optimal alignment of the head. The head can rotate up to 20°, allowing for perfect adjustment.

Materials

  • implatan®: TiAl6V4 (cementless stem and head components) according to ISO 5832-3.
  • implavit®: CoCrMo (cemented stem components) according to ISO 5832-4.
  • UHMW-PE: according to ISO 5834-2 (PE inserts in stem components).

Coating

  • Head components are coated with TiN (Titanium Nitride).

Product Range

  • Head components: Ø 19mm and Ø 22mm
  • Stem components: 12 cementless and cemented options, Ø 6mm and Ø 8mm, available in Type S, Type 1, and Type 2, each in two lengths: 35mm and 50mm.
  • Collar thickness
    • Type S: 2mm
    • Type 1: 3.5mm

NES Elbow System

The NES system enables a non-constrained replacement of the humeroulnar joint while preserving the physiological range of motion. The minimally invasive surgical technique ensures ligament and soft tissue preservation while meeting the requirement for minimal bone resection.

Indications

  • Rheumatoid arthritis
  • Primary osteoarthritis
  • Post-traumatic osteoarthritis
  • Trauma (non-reconstructable intra-articular fractures of the distal humerus)
  • Post-traumatic conditions (non-healing fractures or persistent dislocations in elderly patients)
  • Postoperative conditions following previous surgeries, with or without the use of implants

Key Features

  • Soft tissue stabilized
  • no forced guidance by implantcomponents
  • Bone-preserving design
    slim design for minimal resection while preserving soft tissue structures
  • Sloppy hinge
    The PE insert allows varus/valgus play, reducing force transmission to the stem anchorage
  • Adjustable constraint options
    • Stabilization clip (semi-constrained)
    • Coupling ring (constrained)
  • Humeral offset
    Allows adjustment of the joint line and soft tissue tension (+5mm, +10mm)
  • Physiological range of motion
    Flexion up to 160° and hyperextension possible

Materials

  • implavit®: CoCrMo according to ISO 5832-4 (humeral and ulnar components)
  • implatan®: TiAl6V4 according to ISO 5832-3 UHMW-PE: According to ISO 5834-2 (PE spindle of the humeral components)

Coating

  • TiN coating (articulation axis of the humeral components)

Product Range

  • Humeral components: 8 variants (left and right), available in sizes:
    • Small, Large, Large +5mm, Large +10mm
  • Ulnae components: 6 variants (left and right), available in sizes:
    • Mini, Standard, Large
  • Additional stabilization options:
    • Stabilization clip and coupling ring, which can be locked into the lateral recesses of the humeral component
