f ractures of var ious patterns

indicated.

f ractures w ere sustained in sports acti v i ti es; tw elve, i n a

bicycle accident; and four w ere a gunshot w ound.

A ssociated injuries w ere ex trem ely com mon and

played an important part i n the determ ination of ini ti al treat-

ment of the f racture and in the rehabi l i tati on of the patient.

O ne hundred

and

f orty - three patients had injur ies to the

head, chest, or abdom en. T w enty -sev en had a bi l ateral f em -

oral f racture; f i f ty -f our had ipsi l ateral f emoral and tibial

f ractures; and tw enty -seven had an ipsi l ateral f racture of the

hip, i ncluding f emoral neck and intertrochantenic f ractures.

E ighteen had an ipsi l ateral patel lar f racture and tw enty -three

sustained signi f i cant ipsi l ateral l i gam ent injuri es of the k nee.

O nly tw elve patients had an associated arterial i njury and

only ten had an associated nerve injury .

  reopera tive T rea tm en t

M e th o d s

Emergency care w as given, w i th special attenti on to

cardiopulm onary status, abdom inal status, and the status of

the central nerv ous sy stem . R oentgenogram s of the injured

femur w ere then m ade, as w el l as routine roentgenogram s

of the pelv i s and ipsi l ateral k nee. Ex am ination of the k nee

for points of tenderness al l ow ed detecti on of related l i ga-

ment injuri es. T he arterial status of the low er l imb w as

analyzed caref ul l y , parti cular l y w hen the f racture w as in the

distal one-thi rd of the femur. T he patient w as then placed

in skeletal tracti on in the emergency room. U sual l y balanced

suspension tracti on w as used because i t prov ided greater

comf ort f or the patient, but f i x ed tracti on w as appl i ed i f the

patient had to be transported. W e used rather strong tracti on,

ranging f rom tw enty -f i ve to thi r ty - f i v e pounds (elev en to

si x teen k i logram s) in w om en and f rom thi r ty - f i ve to f orty -

f i ve pounds (si x teen to tw enty k i l ograms) in men. Suf f i cient

tracti on w as appl i ed to restore normal f em oral l ength or to

sl i ghtl y di stract the f racture. L ateral roentgenograms w ere

m ade to ascertain the adequacy of the tracti on because an-

teroposterior roentgenograms can lead to a f al se measure-

m ent of di str acti on’ { 176} .

Earl y in the series, the need f or preoperati ve distracti on

of the f racture w as not suf f i cientl y appreciated. Exper ience

show ed, how ever, that w hen the f racture w as al l ow ed to

shorten, reduction became extremely di f f i cul t. T hus, w e

began to emphasize tracti on as a v i tal part of the delay ed

procedure. W e prefer to gain sl i ght di stracti on preopera-

ti vel y on the hospi tal w ard and to use m inimum tracti on

dur ing operati on.

A l though w e used prophy lacti c antibioti cs routinel y ,

w e changed the drug regimen during the period o f t h e study.

H eal ing w as unev entful , and the nai l w as remov ed one y ear

recurrence.

T he second infecti on w as in a patient w i th an open

fracture

that w as debrided routinel y . A delayed closure w as

performed

af ter one w eek, at w hich tim e the w ound ap-

peared clean. T he f racture w as nai l ed f ourteen days af ter

w i th antibioti cs and w ound dressings. T he f racture pro-

A l though spores w ere seen in the specim ens tak en at the

years of f ol l ow -up.

T he thi rd inf ecti on developed in a nineteen-year-old

spl i t segm ental f racture of the r ight femur. I ntram edul lary

several day s af ter

of the nai l w as decom pressed. Serial dressing changes w ere

bone-graf ti ng w as perf ormed. A t f our-year fol l ow -up ex -

am ination the patient had sol i d bone union, no signs of

inf ecti on, and 135 degrees of k nee f lex ion.

A fourth inf ecti on w as seen in a f i f ty -seven-year-old

of long bones. H e underw ent closed intramedul lary nai l i ng

compression of the nai l , the w ound healed w i thout any sign

of subsequent infecti on.

T here w ere four patients w i th non-union, an incidence

of 0.9 per cent for the ser ies” . One non-union occurred in

a seventy -three-year-old w oman w i th a grade-l I open f rac-

tune in the distal one-thi rd of the f em ur. T he w ound w as

debr ided and intramedul lary nai l i ng w as performed im me-

diatel y . T he w ound healed uneventf ul l y , but nine months

af ter the injury the patient sti l l had sl i ght aching at the

f racture si te; roentgenograms show ed a non-union. T he nai l

w as replaced w i th a larger one, and f our months later the

bone appeared to have uni ted.

T he second non-union occurred in an eighteen-year-

old w oman w hose injuries included a m assivel y sw ol len

thigh and a spl i t segmental f racture of the f emur. T he f rac-

tune w as nai l ed tw o w eek s af ter injury , and despi te attempts

to maintain the length of the femur by tracti on, shortening

occurred. T he nai l w as reinserted but again shortening be-

came ev ident despi te the appl i cati on of thi r ty - f i v e pounds

(si x teen k i l ograms) of tracti on, and the nai l w as again rein-

serted. A t three months the f racture w as sti l l tending to

shorten even w i th tw enty -f i ve pounds (elev en k i l ogram s) of

tracti on, and i t w as thought that the f racture w as not heal i ng

i n a sati sf actory posi ti on. T herefore the f racture w as exposed

bone-graf ti ng w as perf ormed. T he patient w as considered

to have had a non-union despi te the f racture’ s progress to

T he thi rd non-union occurred in a six ty -seven-year-old

Discu s s i o n

In the p resen t serie s o f 520 f em oral-sh af t f ractu res

treated by the sam e m ethod , in tram edu llary nailing , it is

im po rtan t to no te that alth ough w e chose th at sin g le fo rm

and techn iq ue used f or in tram edullary nailing , and in the

In the y ears encom passed by th is stud y there w ere

m ajo r adv an ces in traum a care at ou r institu tion , and ou r

ov er-all ap proach to patien ts w ith f rac tures o f the f em u r

changed accord ing ly . In 1968 , w h en th is serie s began , the

prev alen t attitu de w as that if the patien t surv iv ed af te r h ours

in the em ergency room and day s or w eek s on th e hosp ital

w ard or in the in tensiv e -care un it, h e o r sh e w as then con -

s idered a cand idate for in tram edullary nailing . W ith con -

tinued im p ro v em ents in the care o f the traum a v ic tim at

ev ery stag e o f treatm en t, w e g radually changed to a m ore

agg ressiv e approach , and now attem pt im m ediate f rac ture

f ix ation . T he ob jec tiv e is to aid th e patien t’s su rv iv al as

w e ll as to enhan ce the fu nc tion o f the lim b . C on tinual up-

p lacem ent o f the traum a patien t u nder the care o f the g en eral

enhanced patien t care.

E arly in the serie s o ur g reat concern ov er th e po ssib ility

o f f at em bolism f rom in tram edullary ream ing and nailing

led us to d elay the nailing fo r f iv e to sev en day s af te r in jury .

D uring the last d ecade , how ev er, w e hav e p erfo rm ed in tra-

W ith atten tion to b lood-gas m easurem en ts, th is sy ndrom e

the m o re seriously in jured the patien t w as, the greater w as

the need for earlie r in ternal f ix atio n .
