Meta-diaphyseal atrophic nonunions generally respond better to absolute than
relative stability. I presume your "freshening up" would involve taking this
nonunion down to obtain an anatomical reduction, after which absolute
stability might best be achieved with interfragmentary compression using a
blade-plate, or, as others have suggested and I would prefer, if it were
available, a locking distal femoral plate. If appropriate bone contact could
be achieved, fixation might be enhanced significantly by using the external
tension device to compress the fracture. I'd add bone graft.



The following reference, which describes the short "GSH" retrograde femoral
nail, seems to offer relevant evidence:

J Orthop Trauma. 1995;9(4):285-91.
Distal femoral nonunion: treatment with a retrograde inserted locked
intramedullary nail. Koval KJ, Seligson D, Rosen H, Fee K.
Between March 1989 and August 1993, 16 distal femoral nonunions (16
patients)
were treated using the supracondylar intramedullary nail. The time between
the
initial event and retrograde nailing averaged 33 months. The nonunion level
was
infraisthmal in four patients and supracondylar in 12. Operative technique
involved retrograde insertion of a reamed supracondylar intramedullary nail
through the intercondylar notch. Follow-up was available on all patients and
averaged 20 months (range 9-46). Four nonunions (25%) united with a single
surgery at an average of 17 months. A fifth nonunion united at 21 months
after
nail dynamization and subsequent nail breakage. The nonunions of two
additional
patients united after exchange of a broken retrograde nail. Additional
surgical
procedures were performed in six of the remaining nine patients in an
attempt to
gain union. At an average follow-up of 16 months (range 9-23), none of the
nine
had united. Nine nails fractured at an average of 11 months, all through a
screw
hole near the nonunion. Based on these results, we cannot recommend use of
the
supracondylar intramedullary nail in its present form for the treatment of
distal femoral nonunions.

Would anyone use a retrograde nail in this case? (after freshening up the #

Dear all
I have a similair case who had non -union after supracondylar nail, which broke at the fracture site. I had to take the nail out and then fixed it with LISS_DF (locking plate) I did use the bone graft. fracture healed with 3 months.
If fixation is solid fracture unite very well provided the environment of the fracture is suitable.
anothe non-union was fixed with Fixed angled monoblock plate. (not DCS) and fracture healed, when augmented with bone graft.
My experience is very pleasantuptill now.
thank you all for keeping us updated

Dear gavin
I am bit reluctant to use retrograde nail, as the will still be too long working length and mor movement on fracture site, there is risk of non-union as more then required elasticity( strain theory of peren).
I would prefer some kind of absolute stability, more like fixed angled device
thank you
