Rotational cutting tools, known as reamers, are used in a variety of orthopaedic surgeries ranging from intramedullary nailing of long bone fractures to total joint arthroplasty.
What is an orthopedic reamer?
Orthopedic Reamers are manual surgical instruments used to open and enlarge the medullary canal for the insertion of various devices during prosthesis implantation or fracture fixation procedures.
What does reaming a bone mean?
Reaming increases the inner diameter of the medullary canal by removing the inner cortical bone and a larger diameter nail can be used. This provides better stability by increasing the interfer- ence and thus the mechanical properties of the nail [2, 5].
Are reamers reusable?
Expansion reamers are precision tools that can be reused multiple times and are generally used for reaming abrasive material. They are built with slots cut between the flutes and a tapered screw in the head.Feb 3, 2015
What is reaming medical?
Reaming is done to enlarge the medullary canal of bone which is narrowest at isthmus and can accommodate nail of the size there if not reamed, but as the thicker the diameter of nail better it is , so surgeons prefer to introduce thicker nail (i.e. size 11, 12 in femur or 10,11 in tibia etc) by manual or power reaming.
What is an IM nailing?
An intramedullary nailintramedullary nailAn intramedullary rod, also known as an intramedullary nail (IM nail) or inter-locking nail or Küntscher nail (without proximal or distal fixation), is a metal rod forced into the medullary cavity of a bone. IM nails have long been used to treat fractures of long bones of the body.https://en.wikipedia.org › wiki › Intramedullary_rodIntramedullary rod - Wikipedia is a metal rod that is inserted into the medullary cavitymedullary cavityThe medullary cavity (medulla, innermost part) is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored; hence, the medullary cavity is also known as the marrow cavity.https://en.wikipedia.org › wiki › Medullary_cavityMedullary cavity - Wikipedia of a bone and across the fracture in order to provide a solid support for the fractured bone.
