LUXATION OF THE FEMUR. 
Luxation of the Femur— continued . 
Forwards— 
Luxatio iliaca. 
Symptoms. —Ab¬ 
duction and rotation 
outw a r d s. When 
standing on the dis¬ 
eased side the hip 
is dropped, the tro¬ 
chanter is prominent, 
the skin covering it 
tense, lies in folds 
over the quarter and 
stifle. The limb ap¬ 
pears shortened, the 
stifle turned out¬ 
wards, the femur 
almost perpendicular. 
Stockfleth saw this 
dislocation in both 
limbs in a cow. 
Prognosis. —Un¬ 
favourable in horses 
and cattle. If re¬ 
placement is unsuc¬ 
cessful, partial re¬ 
storation of move¬ 
ment may follow the 
formation of a false 
joint, though lame¬ 
ness remains. Re¬ 
duction is readily 
followed by relapse. 
Treatment. —As 
usual in such cases. 
Extension and thrust¬ 
ing the head of the 
joint backwards. 
Backwards— 
Luxatio ischiatica. 
Symptoms. -The 
animal generally lies 
on the belly. The 
limb is abducted and 
rotated inwards. 
When standing, a 
furrow is visible in 
front of the biceps 
muscle and a depres¬ 
sion in the region of 
the trochanter. The 
skin of the quarter is 
tensely stretched. 
Swelling and pain 
slight. A loud sound 
is produced in conse¬ 
quence of the head of 
the femur striking 
the ischium when the 
trochanter is struck 
or the extended limb 
suddenly thrust back. 
Lameness, both when 
the limb is carried 
and when weight is 
placed on it. Trail¬ 
ing of the limb, which 
is carried in a circle, 
the toe often rubbing 
the ground. 
Prognosis unfa¬ 
vourable. Stockfleth 
only saw recovery in 
two out of nine cases. 
Treatment.— To 
attempt replacement, 
extension whilst the 
..imb is in a position 
of abduction, fol- 
owed by rapid ad¬ 
duction and rotation 
outwards. 
Inwards— 
( a ) Luxatio pubica. 
( b) Luxatio obtura- 
toria. 
Symptoms. - (a) 
In L. pubica abduc¬ 
tion and rotation 
outwards. Rolling, 
insecure gait, troch¬ 
anter indistinct, a 
depression over the 
hip-joint, passive 
mobility, abduction 
abnormal, adduction 
limited. 
(If) L. obturatoria. 
Generally the same 
symptoms. The head 
of the bone can be 
detected (especially 
when the limb is 
moved) by examina¬ 
tion per anum or 
vagina m. 
Prognosis like¬ 
wise unfavourable. 
Reduction only pos¬ 
sible in very recent 
cases. 
Treatment.— 
Powerful extension 
whilst the limb is 
abducted, after 
which reduction 
must be effected by 
rotation and adduc¬ 
tion. 
Outwards— 
Luxatio supra 
cotyloidea. 
Symptoms,— 
Shortening of the 
limb and adduction. 
Abduction and 
movement limited. 
Swelling over the 
hip-joint. Trochan¬ 
ter prominent. 
Prognosis.— 
Only favourable in 
dogs when seen 
early. Later, con¬ 
tinuous lameness. 
In large animals, 
still less chance of 
permanent recovery. 
Treatment.— 
Extension of the 
flexed limb in the 
direction of abduc¬ 
tion. Replacement 
to be effected by 
movements of ad¬ 
duction.
