Question ID: 100315
Gamma nail is an interlocking nail used for the treatment of
Intertrochanteric fractures of the femur. I woulk like to know where i
can get information on the web free of cost about :(1) the gamma nail,
(2) the procedure of using the nail, (3) studies detailing the use of
the gamma nail, (4) comparative studies between use of the gamma nail
and other treatment methods. i need this information for my research
paper on the use of gamma nail for the treatment of intertrochanteric
fractures of femur.

Its surprising that no one has even attempted my question. Looks to me
the pricing is a problem. Well that is something i can afford! Anyway
another day to go... if someone is intrested i can hike the price
depending on the material provided. By the way this shows how
commercial compulsions can restrict the freedom to share information
on the net.
If there is no answer then i guess i have to do the search myself and
i will be back soon with answers.

Given the large volume of documents on the internet and the modest
pricing of your question, I have attempted to locate some helpful
resources for you without spending an inordinate amount of time on the

First, here is an excerpt from Campbell's Operative Orthopaedics, 9th

"Short, interlocking intramedullary devices, such as the gamma nail
and intramedullary hip screw, have been introduced for use in
intertrochanteric fractures, and femoral reconstruction nails have
been used for difficult fracture patterns. These intramedullary
devices are theoretically more load-sharing with the medial cortex of
the femoral neck than are lateral cortical constructs. Because of the
more medial placement of the intramedullary nail compared to the side
plate of the compression hip screw, the bending moment at the
nail-screw junction is lower than that at the plate-screw junction.
Other potential advantages of intramedullary fixation include a
smaller operative exposure and possibly a shorter operative time.

To date, clinical studies with the gamma nail and similar devices have
not demonstrated a clear advantage in the treatment of most
intertrochanteric fractures. Goldhagen et al. compared the gamma nail
to a compression hip screw and found no differences in surgical time,
blood loss, or fluoroscopy exposure. Clinical rates of healing have
been similar for the two devices, but a 3% to 6% incidence of
secondary fracture at the tip of the intramedullary device has been
reported. The gamma nail does appear to have some advantage in certain
unstable fractures, especially those with reverse obliquity and
subtrochanteric extension that cannot be easily treated with standard
hip compression screws."

Also, this seems to be a good overview and resource, written by an MD.

I did a Medline search for “gamma nail” limited to items with
abstracts. There are 165 journal articles. I have access to a number
of scientific journals through my university computer system and
library if we need to look at more full-length articles. This should
link you to my search.

I do hope this helps. Please let us know if you need more assistance,
