Согласен с коллегой , а вариант с меньшими финансовыми затратами и практически с тем же конечным результатом ( несколько повременить с нагрузкой ) - пластина на 12 - 14 отверстий, 2-3 с фиксацией в шейке ( лучше использовать со спонгиозной резьбой на всю длину шурупа ).

"There are different ways of skinning a cat" as Anil would put it. If I were to do this, I would open up, remove the earlier implants, reduce the fracture accurately,plan a 90* Richards, do a couple or more of interfrag screws first, in locations where it would not come in the way of the screws of the plate, (which then makes the femur one piece) then complete the Richards fixation.This is in spite of the fact that I am a vehemant interlocker.
A Sirus nail if guided properly and one gets a reduction can be used too. The different holes in the proximal part of the nail will allow screws in the nck and across the fragments and also lock distally. I might be spending more time doing that than the 90* Richards, but that is one very good way of tackling this. One needs to open only minimally to remove the earlier implants.

Perhaps several cerclage wires, then screw removal and IM nail with proximal
fixation into head.
Cerlage wires by themselves are tempting but I suspect significant risk of
failure.

That's a great case illustration provided by Bill and HWBF and the blade plate/valgus producing osteotomy looks like a good option for Alex's case.
A particularly interesting aspect of Alex's case is the 2 years since screw placement. We've been leaving proximal screws in place indefinitely for years and haven't seen very many late fractures around them. The problems, if they occur, tend to be loss of fixation or early fracture from distal or large or many drill holes or the occasional arthritic hip requiring screw removal for femoral prosthetic placement. Perhaps this fracture at two years post op is merely a very uncommon and unlucky patient? Or have others seen this specific problem more frequently?

I am not sure abut is it even technically doable in the such fracture with splitiing in frontal plane.
I wonder why so little colleagues supported option of IM nailing.

In our settings it is uncommon injury.

Regarding this specific patient, it is quite difficult for me to discern the exact fracture pattern and therefore treatment suggestions. It appears to be a spiral fracture starting just proximal to the less trochanter and extending distally 6 or more cm into the shaft with medial displacement of the distal fragment. The lesser troch is a seperate fragment. The 2 year old femoral neck fracture appears to have healed in good position I really can't tell where the fracture starts laterally, but presumably it's near the distal most screw.
I can't tell if there is further comminution of the shaft or the greater trochanter. I can barely see the fracture on the lateral radiograph. I'm not sure but I don't see AVN of the femoral head nor OA of the hip. Her overall bone quality appears normal for a 68 year old. I don't see any loosening of the screws but I can't tell for sure.
The fracture extention well into the shaft makes intramedullary fixation somewhat more appealing than plate fixation and contrasts with the case posted by Bill. A reconstruction nail with proximal locking into the femoral head and neck after screw removal and reduction would be reasonable.

Еще одна боковая проекция. На сегодня назначен закрытый интрамедуллярный остеосинтез. Реконструкционного гвоздя для этой больной не нашлось, придется делать обычным.
Another lateral view. A closed nailing is scheduled for today. No reconstuction nail is available so a usual one is planned.

This is a well known complication due to the low entry point of the screws. It is a technical failure rather than Osteoporosis.

Вчера оперировали - винты удалены через 1 прокол. Затем выполнили закрытый интрамедуллярный остеосинтез без расверливания бесканальным гвоздем 13 мм (реконструкционного для нее не нашлось). Гвоздь заперт статически - в проксимальный отломок 3 винта 6 мм, в дистальный - 1.
Учитывая варус сросшейся шейки, постарался вальгизировать проксимальный отломок, насколько гвоздь позволил. Результат в приложении. Картина перелома видна лучше, чем на начальных снимках.
Интересно, что линия перелома не выходила на отверстия от винтов, а была кзади. Комментарии?
The screws were removed through a stab wound. Then a closed insertion of an unreamed solid nail 13 mm was performed and the nail statically locked - 3 screws 6 mm in the proximal fragment and 1 in the distal.
Considering varus of the healed neck i tried to get some valgus to the proximal fragment as the nail allowed. The result attached. The fracture pattern can be seen better than in the initial films.
Any comments?

This looks like a good solution, technically well done and likely to succeed. I hope you will give us some follow-up in 3 months.
My question (purely to keep the discussion alive :-) is why do you use an unreamed technique? There are now several studies comparing reamed and unreamed femoral nails with increased non-union and mal-union rates in the unreamed group. A recent study from Duke showed that the amount of fat embolism during unreamed nailing was the same as during reamed nailing, measured by Trans Esophageal Echo-cardiogram. So what is the advantage of unreamed nails? In this particular case?
The following search in PubMed uses the search string (("Femoral Fractures/surgery"[MAJR:noexp] AND "Bone Nails"[MeSH]) AND unreamed[All Fields]) and yields 45 papers mostly on the subject. There are at least three different prospective randomized trials comparing reamed vs unreamed all with the same findings.
I feel even more strongly on the subject of unreamed tibials nails and deplore the current SPRINT trial. The money would be better spent comparing reamed IM fixation of the tibia to percutaneous plate fixation or ex fix. Is everyone aware that there have never been a randomized prospective trial in closed tibial fractures to show that IM nails are superior to old fashioned AO plates?! Yet we have swung almost completely in that direction. Of course, you could also say that there has never been a randomized controlled trial to show that total hip replacement is better than a Girldlestone; but I submit that the case for nailing tibias is much less secure.

Just because we have only solid nails, and 13 mm is a thickest available one, and due to her osteoporosis the nail passed through the canal without reaming.

I completely agree that for primary nailing the only advantage of unreamed technique is few saved minutes.

Do you really suppose this topic is so actual? Differencies looks so self-evident.

Alex> Can't enough evidence be provided with retrospective studies?

The largest metaanalysis on this subject was published in 1999 in the Canadian Journal of Surgery. The following is the
abstract
10166. Coles, C. P. and Gross, M.,
Closed tibial shaft fractures: management and treatment complications. A review of the
prospective literature. Can.J Surg 43:256-262, 2000.
OBJECTIVE: To compare the results and complications of the various modalities for treating closed fractures of the tibial shaft described in the prospective literature.
DATA SOURCES: A MEDLINE search of the English language literature from 1966 to 1999 was conducted using the MeSH heading "tibial fractures." Studies pertaining to the management of closed tibial shaft fractures were reviewed, and their reference lists were searched for
additional articles.
STUDY SELECTION: An analysis of the relevant prospective, randomized controlled trials was performed. Studies including confounding data on open fractures or fractures in children were excluded. The 13 remaining studies were reviewed.
DATA EXTRACTION: Raw data were extracted and pooled for each method of treatment.
DATA SYNTHESIS: The 13 studies described 895 tibial shaft fractures treated by application of a plaster cast, fixation with plate and screws, and reamed or unreamed intramedullary nailing. Although definitions varied, the combined incidence of delayed and nonunion was lower with operative treatment (2.6% with plate fixation, 8.0% with reamed nailing and 16.7% with unreamed nailing) than with closed treatment (17.2%). The incidence of malunion was similarly lower with operative treatment (0% with plate fixation, 3.2% with reamed nailing and 11.8% with unreamed nailing) than with closed treatment (31.7%). Superficial infection was most common with plate fixation (9.0%) compared with 2.9% for reamed nailing, 0.5% for unreamed nailing and 0% for closed treatment. The incidence of osteomyelitis was similar for all groups. Rates of reoperation ranged from 4.7% to 23.1%. CONCLUSIONS: All forms of treatment for tibial shaft fractures are associated with complications. A knowledge of the incidence of each complication facilitates the consent process. To fully resolve the controversy as to the best method of treatment, a large, randomized, controlled trial is required. This review more precisely predicts the expected incidence of complications, allowing the numbers of required patients to be more accurately determined for future randomized controlled studies
Highlights are
- delayed, non-union and malunion lower with plates
- superficial infection more common with plates
- deep infection the same for all treatment groups.
So, no! I don't think the advantages of one technique over another are self-evident; except that unreamed tibial nails seem to be the worst option. I do emphatically think the subject needs to be subjected to rigorous scientific investigation. Since that study closed in 1999 we have begun to use periarticular plates which can be inserted in a closed fashion with just a small opening at top and bottom leaving the blood supply of the fracture fragments undisturbed. On the other hand, perhaps we have become more skilled at doing closed IM rod fixation and so have less malunions.

Dear Alexander,
Very well done. This nail that You have used is something new to me. This has different holes proximally than the routine nail. After getting such a good reduction,(which I had not anticipated) if there were more holes beyond the screws that you have put then screws could be introduced thro the nail across the # site too.

Because of AO/Mathys/Synthes activity here, many local vendors offer only rather cheap copies of UFN/UTN. Hollow nails available at the local market are from abroad so more expensive.
Another reason is higher infection risk with hollow nails after secondary nailing after ex-fix.
