Functional Results of Hip Arthroplasty with Acrylic
Prosthesis, available at DOI 10.1007/s11999-008-0572-1.
Robert Merle d’Aubigne´ was born in 1900 in Neuilly, from
a Huguenot family [9]. He had a classical education at the
Lyce´e Pasteur [5] and at age 17 wanted to enlist in the tank
corps, but with two brothers in the service and his mother
objecting, he ‘‘yielded to my mother’s wishes’’ [5]. During
WWI, his school was, however, turned into a hospital,
where he met Dr. Philip D. Wilson, Sr. He finally was
called to service in 1918, two months before the Armistice.
He had his medical training at the Medical Faculty in Paris,
but found it ‘‘disappointing.’’ He later commented,
‘‘…Misery, resignation, and death on one side, pretension
and highfalutin speech on the other, was the most common
spectacle’’ [5]. (Merle d’Aubigne´ was fluent in English.)
He then served as an assistant in general surgery for
12 years at the Hoˆpital de Vaugirard, during which time he
developed an interest in orthopaedic surgery. ‘‘The prestige
of visceral surgery absorbed the interest of the senior staff.
The lesions of the motor system, numerous accidents,
tuberculosis, and arthritis were more or less abandoned to
the junior staff’’ [5]. In the thirties he spent time with
Bo¨hler in Vienna and Putti in Bologna. During WWII he
initially served as a captain in a mobile unit, but during the
occupation balanced his life as a surgeon and serving in the
Resistance [9].
When De Gaulle returned to France in 1944, Merle
d’Aubigne´ was appointed at the newly formed health
commission to reorganize the health military services.
While not entirely happy with his administrative work, in
December, 1944 he went to England to visit prominent
surgeons. This trip had a major influence on his life: first he
met influential people and second he had a better sense of

orthopaedics as a specialty and the task ahead of him. He
commented, ‘‘Pour moi, ce fut une experience inouı¨e qui
bouleversa ma vie professionelle’’ (‘‘For me, it was an
unbelievable experience that profoundly changed my pro-
fessional life.’’) [6]. He met Sir Reginald Watson Jones at
the London Hospital, Sir Jim Seddon in Oxford, Franck
Stinchfield at an American center in Cirencester, and Sir
Ludwig Gutmann. He also was invited to the Royal College
of Surgeons and later developed close relationships with
many of the members.
When he returned to France, he had clearer ideas as to
what kind of department he wanted and how to achieve his
goal. He initially worked at the Centre de Chirurgie
Re´paratrice newly created by the military at a small private
hospital, Hoˆpital Leopold Bellan. From there the team was
moved to the Hoˆpital Foch, where he met and worked with
Michel Postel, Jacques Ramadier and others [5]. Merle
d’Aubigne´ then was offered the chair at the Hoˆpital Cochin
in 1948, where he remained until he retired in 1970.
In the literature there has been some confusion about the
last name, properly ‘‘Merle d’Aubigne´.’’ (For the Classic
article we republish this month from The Journal of Bone
and Joint Surgery PubMed improperly lists the author’s
last name as ‘‘d’Aubigne’’ and ‘‘RM’’ as the initials.) Merle
d’Aubigne´ describes the origin [5]:
‘‘I bear the first and second names of my great
grandfather, Aime Robert Merle d’Aubigne´, who
created in Geneva an international postal service and
disappeared in 1799 during the Napoleonic wars
while carrying the mail from Geneva to eastern
Europe. His father, Franc¸ois Merle, was the son of a
silk stockings maker from Nimes, and his mother,
Elisabeth d’Aubigne´, was the great granddaughter of
Nathan d’Aubigne´, son of the poet Agrippa d’Au-
bigne´ and only survivor of the name. They were all
French Huguenot refugees in Geneva. To preserve
the name of d’Aubigne´, it was joined with Merle.’’
In this issue we republish his description of the so called
‘‘Merle d’Aubigne´-Postel’’ rating scale he published in
English in the American volume of The Journal of Bone
and Joint Surgery in 1954 [1]. It is perhaps not widely
known in the English-speaking world that he in fact pub-
lished three closely related rating scales (in 1949 [8], 1954
[1], and 1970 [4]), providing changes when he believed
them necessary. The first written report of the rating scale
was published in the Revue de Chirurgie Orthope´dique in
1949 [8]. (Supplemental materials are available with the
online version of CORR.)
In this article, Robert Merle d’Aubigne´, Jean Cauchoix,
and Jacque Odilon Ramadier noted this rating had been in
use for over three years and was first presented at the
International Congress of Orthopaedic Surgery in 1948 in
Amsterdam. At that time, no widely used scale for evalu-
ation of hip function had yet penetrated the orthopaedic
community. In this first publication of the rating scale, the
authors reported 92 femoral neck nonunions treated with

nailing and on 75 hip prostheses. The authors also gave us
some of the reasons to use such a rating scale. They
acknowledged important series of the results of cervico-
capital prostheses had been published but all, according to
the authors, had been evaluated with a categorical rating
such as excellent, good, average and poor and none took
into account the state of the joint preoperatively. Therefore,
they proposed a new rating system that dissociated each of
the three following dimensions of hip function: pain, ability
to walk, and mobility, in seven ordered categories
(Table 1). Their rationale for using such a rating scale was
that it should better differentiate the various dimensions
and levels of hip function, and that it should allow a more
objective assessment in a department from one surgeon to
another and in the literature from one study to another. In
this first report, pain was rated from ‘‘No pain’’ to ‘‘Pain is
intense and permanent.’’ Intensity of pain and the activity
with which the pain was present determined the level of
pain. Ability to walk was rated from ‘‘normal’’ to
‘‘impossible’’ and the use of walking aids was included in
this category: the more walking aids are necessary, the
lower the level of the category. The last dimension of the
scale assessed the mobility of the joint from ‘‘normal
flexion [ 90 and abduction [ 25’’ to ‘‘ankylosis of the
hip in a bad position.’’ As the range of mobility in flexion
decreased and joint contractures appeared, the level of the
category decreased. The overall score was determined by
the sum of the three categories obtained from each
dimension and the rating ranged from 0 for a patient with
ankylosis of the hip, who could not walk with or without
walking aids, and suffered from permanent and intense
pain to 18 for a patient able to walk freely, with no pain at
all and with a mobile joint. Pain, walking ability and
mobility of the joint all contributed equally to the overall
score. With the help of this rating scale, the authors
compared preoperative and postoperative mean levels for
each separate dimension of the score for various hip
abnormalities. They were able to discern the effect of the
treatment of femoral neck nonunion from that of the
treatment of rheumatoid arthritis. The treatment of femoral
neck nonunions yielded an important improvement in pain
and ability to walk but not much in mobility because this
dimension was not substantially altered postoperatively; in
contrast, the effects of the treatment on rheumatoid arthritis
were dramatic with regard to pain and mobility, but not for
the ability to walk because of the frequent impairment of
other joints.
In 1954, Robert Merle d’Aubigne´ and Michel Postel
reported the functional results of 323 patients with trau-
matic, degenerative conditions and subluxations treated
with the acrylic prosthesis in the Journal of Bone and Joint
Surgery [1]. (It is this article that gave rise to the com-
monly used term ‘‘Merle d’Aubigne´-Postel score’’ in
English, despite the earlier publication in French with other
authors. Readers should also be aware of the order of the
authors in this publication since the literature incorrectly
contains many references to the ‘‘Postel-Merle d’Aubigne’’
or ‘‘PMA’’ score.) The method used for grading the func-
tional value of the hip was adapted from the earlier
published in 1949 [8] and the scale was amended with
slight modifications (Table 2). The pain and ability to walk
dimensions were unmodified. The grade 4 of mobility ‘‘can
tie shoelaces’’ was changed to ‘‘can reach his foot.’’ Most
probably over the intervening years, users of the scale
expressed difficulty in rating patients who were unable to
tie shoelaces for various reasons but still able to reach their
foot. The mobility of the joint was therefore more accu-
rately assessed by this modified description. The sixth and
seventh categories of this component were also modified.
From the beginning, Merle d’Aubigne´ was willing to

include with the mobility in flexion a measure of other
important mobility restrictions. In the 1949 scale, flexion
was combined with abduction as limited to 25 or above
25 for grades 5 and 6, respectively, while in 1954 the same
two categories were combined with flexion but rated with
abduction of at least 15 and abduction to 30, respectively.
However, as is common with many categorical ratings,
Merle d’Aubigne´ combined findings: flexion and abduction
and ability to tie ones shoes or reach the foot (see mobility
column in Tables 1 and 2). There would be admittedly rare
cases where a patient would not fit any of the categories
owing to a peculiar combination of findings. In these cases,
the rater would have to make a best guess as to the correct
category and adding to the interobserver variability of such
scores. (Partly for this reason Turchin et al. suggested raw
scores better reflect results than such categorical ratings
[10].) The point Merle d’Aubigne´ was trying to develop
was the importance of these deformities in the assessment
of the results of hip operations from a preoperative to a
postoperative status. Merle d’Aubigne´ and Postel classified
the results in two ways: ‘‘absolute results (the evaluation of
the functional value of the hip after the operation) and
relative results (the appreciation of improvement between
the preoperative and the postoperative functional states)’’.

Moreover, because the authors believed a painless joint and
the ability to walk were more important than mobility, the
improvement in these two dimensions of the score were
multiplied by two to assess the relative results of the pro-
cedure. Therefore, a successful arthrodesis giving a
painless joint and the possibility to walk without a cane
would not unduly suffer from a mobility score of only one
and would remain comparable to a successful arthroplasty.
The last version of the scale appeared in the Revue de
Chirurgie Orthope´dique in 1970 [4], after Carroll B. Larson
proposed the Iowa Hip Rating in 1963 [3] and William H.
Harris proposed the now widely used Harris Hip Score in
1969 [2]. Merle d’Aubigne´ objected to the Harris Hip
Score in that it only accorded five points to the mobility
dimension that could under certain circumstances rate an
arthrodesis above an arthroplasty. The fact that this remark
seemingly contradicted his previous thoughts on reducing
the effect of improvement in mobility on the overall score
may be attributable to the then recent use of total hip
arthroplasties over arthrodesis and that consequently
mobility had become more important. This article is the
first devoted to the scale per se and contains his rationale.
Compared to previous versions the scale published in 1970
is easier to use (Table 3). Categories 0 and 6 of the pain
dimension were not changed from previous reports but
categories 1 to 5 have been clarified: the pain score
increases (better) with increased duration of walking
without pain. This makes it more reproducible than the
rating of previous levels of activity. The mobility dimen-
sion was also simplified by deducting points for patients
who present with joint deformity and less than 50 of
flexion. Because joint limitation of abduction, adduction or
internal rotation are more problematic than joint deformity
in flexion or external rotation, in presence of the former
two points are subtracted while in the latter only one point.
Finally, the walking ability remained similar to that of
1954 and 1949. This article was republished in 1990, a year
after Merle d’Aubigne´’s death [7]. (Supplemental materials
are available with the online version of CORR.)
Robert Merle d’Aubigne´ made great contributions to
orthopaedic surgery, not the least of which was his early
attempt to more objectively assess disability in patients
with hip disease and the effects of surgical treatment. He
influenced a generation of surgeons, as well as the training
of French surgeons. We hope readers will find this review
of his well-known rating scale of particular interest.
