What is bone reamings?
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].
What is an intramedullary nailing?
An intramedullary nail is a metal rod that is inserted into the medullary cavity of a bone and across the fracture in order to provide a solid support for the fractured bone. Intramedullary nailing is currently considered the “gold standard” for treatment of femoral shaft fractures (Rudloff 2009).
What is closed intramedullary nailing?
Abstract. For many fractures of the femoral shaft, closed intramedullary nailing will not control rotation or telescoping of the fragments. Locked intramedullary nailing combines closed nailing with the percutaneous insertion of screws that interlock the bone and nail.
What does a bone reamer do?
The flexible reamer system is intended to clear the medullary canal of bone marrow and debris and to effectively enlarge the medullary canal of long bones for the acceptance of an intramedullary nail.
What is reaming in surgery?
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 a reamer in surgery?
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.
How do you do interlocking nails?
The nail is coupled to an insertion handle via a nail extension. It is introduced along the anatomical axis of the femur and inserted into the medullary canal of the proximal segment by hand or gentle hammering. The fracture is aligned while the nail is further advanced into the distal segment.
What is Gallow traction?
Gallows traction is a type of overhead skin traction used to treat a broken bone in the thigh or hip dysplasia (hip dislocation) conditions. It is applied on children aged between 0 and 18 months of age who weigh up to 15kgs.
What is femoral reaming?
What is a surgical reamer?
Are there any intramedullary reamings that are unhelpful?
Reamings have therefore been an attractive option as they allow a large area of the intramedullary canal to be sampled without any additional steps in the operative procedure. However, we have found that they are unhelpful in 35% of cases, mainly due to the destructive nature of the technique itself.
How are intramedullary reamings used in radiology?
At the time of surgery such a device could be used to obtain a sample of radiologically suspect bone. Reamings have therefore been an attractive option as they allow a large area of the intramedullary canal to be sampled without any additional steps in the operative procedure.
Can a reaming be used to refute a histological diagnosis?
CONCLUSION We have highlighted the limitations of relying exclusively upon femoral reamings to confi rm or refute a diagnosis of metastatic disease. Reaming is an integral part of implantation of medullary devices and, therefore, there is no harm in sending off such specimens for histological diagnosis.
What’s the difference between reamed and UN reaming nails?
Reaming where we drill the intramedullary canal so we can insert large size diameter nail because stability Is found to be associated with diameter of nail . Large size diameter is more stable . So the golden standard practise is to use reamed nail in long bone. Fracture . Un reamed nail mean small diameter of the nail and so it less stable .
