RIA 2 System (Reamer Irrigator Aspirator)

RIA 2 is intended for the clearing and sizing of the medullary canal, the harvesting of autograft, and the debridement of necrotic and infected tissues from the medullary canal.

  • Designed for simplified assembly
  • For femur and tibia
  • More graft and lower pain scores1

Features & Benefits

ria 2 system reamer irrigator aspirator system


  • Up to 90 cc of graftwith an incision size as small as 2 cm have been reported2
  • Lower total complication rate: 6.0% versus 19.4% from iliac crest bone graft (ICBG) harvesting3
  • Greater level of gene expression associated with vascular, skeletal, and hematopoietic tissue versus ICBG4
  • 73% lower donor site mean pain score than ICBG1

Indication Statement

RIA 2 is intended for use in adults and adolescents (12 -21 years) with closed physes

  • To clear the medullary canal of the bone marrow and debris
  • To effectively size the medullary canal for the acceptance of an intramedullary implant or prosthesis
  • To harvest morselized autogenous bone and bone marrow for any surgical procedures requiring bone graft to facilitate fusion and/or fill bone defects
  • To remove infected and necrotic bone and tissue from the medullary canal in the treatment of osteomyelitis
