3. Resection of the joint is undoubtedly the best operation in the
more severe operations of hallux valgus. Involving the obliteration of
an important articulation, it was feared that it might induce serious
crippling, but the plan has been adopted with perfect success by Mr.
Clutton[14] who, excising the cartilaginous extremities of the bones and
fixing the shafts in suitable position by means of an ivory peg, has
secured the best results. During the last two years I have applied the
principle of the operation recommended for hammer toe. Excision of the
head of the metatarsal bone is performed through a longitudinal incision
over the inner side of the joint, the toe is then replaced and fixed
for three weeks in a slightly extended position by means of plaster of
Paris. The success of these measures is far more complete than could have
been anticipated on theoretical grounds. The distal joint appears to
replace almost perfectly that which is lost, and the locomotion is easy
and unfatiguing. In a case of my own the patient was able to walk twenty
miles a day within three months of the operation.
HALLUX VARUS.
[Illustration: FIG. 15.
Hallux varus. A. Before operation; B. Three years after operation. The
relatively small size of the great toe in B is due to the abnormally
great development of the other toes (not represented in Fig. A).]
The following is a curious example of this rare condition, in association
with macrodactyly. The patient, a boy aged eleven, was admitted into
St. Thomas’s Hospital in March 1887, with a deformity of the right great
toe, dating from infancy. The member was somewhat imperfectly developed,
and projected inwards almost at right angles with the metatarsal bone.
(See Fig. 15, A.) A slightly prominent integumental fold was present on
the inner side of the metatarso-phalangeal joint, and the ligamentous
and other fibrous tissues beneath this resisted the replacement of the
digit in its normal line. The toe could be moved feebly by an effort of
the will, but the abnormal direction of the member prevented the muscles
from exercising any useful function. The smaller toes were distinctly
hypertrophied, but were otherwise well formed. The boy was unable to wear
a boot, and was completely crippled. The toe was apparently useless, but
it was judged advisable to restore it to its natural position rather than
to amputate. This was effected by subcutaneous division of the internal
lateral ligament and the application of a small plaster apparatus.
Fifteen days later the child left the hospital with a light metal splint
fixed to the inner side of the foot and toe. Three years afterwards he
presented himself for examination, and it was found that the good result
was more than maintained, as the toe was not only straight, but had
acquired its normal size and considerable power of movement. The boy said
he was able to walk seven or eight miles without fatigue. The relative
hypertrophy of the lesser toes was still obvious.
