Fragment Fixation System (FFS)


Accomplish the lag screw effect with the ease of a K-Wire – in just one pin. The innovative thread design of the Orthofix Fragment Fixation System auto-compresses bone fragments as the pin is advanced.

Features & Benefits

For bone fragments in upper and lower limbs

  • All implants 120 mm long in a variety of thread lengths cut to length after insertion
  • Excellent stability guaranteed by fine thread and unique design
  • Compression possible between fragments
  • No pre-drilling or pre-tapping required
  • Medium and large sizes can be combined with a washer to improve cortical contact

Physicians Benefits

  • Implants have a three-sided trocar cutting tip and a finely machined threaded section, specially designed to guarantee good purchase in cancellous bone
  • The proximal portion of each implant consists of a smooth shaft, the diameter of which is greater than that of the threaded section
  • The chamfer at the intersection of the threaded portion and the smooth shaft functions to maintain fracture reduction
  • Simplicity saves operative time​1,2​
  • Holding power in bone allows joy stick manipulation of fragments prior to insertion of second implant​​


Small Implants

  • Proximal phalanges in the fingers and toes
  • Metacarpals and metatarsals

Medium Implants

  • Proximal and distal radius
  • Fragments too small for large implants in the humerus, tibia and fibula
  • Middle and distal phalanges in the fingers and toes
  • Fragments less than 3 mm in diameter

Large Implants

  • Humerus
  • Olecranon
  • Patella
  • Tibia
  • Fibula
  • Metatarsal


  • Active infection.
  • General medical conditions including: impaired blood supply, pulmonary insufficiency (i.e. ARDS, fat embolism) or latent infection.
  • For patients with psychological or neurological conditions who are unwilling or incapable of following instructions for post-operative care.
  • Foreign body sensitivity where material sensitivity is suspected, tests should be made prior to implanting.
