Another advantage is the extreme ease with whichdisarticulation may be performed on emergency, no saw being required, and the ordinary bistoury of the pocket-case being quite sufficient for cutting the flaps.
Disarticulation of the entire bone has been very rarely performed.
The disarticulation may finally be completed with great ease, as the shape of the articular surfaces concerned is very simple, and nearly transverse.
When the portion of bone implicated involves disarticulation for its complete removal, the difficulty of the operation is much increased.
In cases where it is found impossible to save any portion of the fore-arm, disarticulation at the elbow-joint may be easily performed.
Disarticulation of the Ramus without opening into the cavity of the Mouth.
Very shortly after writing the above, the patient submitted to the disarticulation and removal of fully half of the jaw, represented here.
Disarticulation of one side of the jaw is not unfrequently necessary; it is absolutely required when the tumour encroaches upon and involves the angle and ramus.
Partial paralysis of the side of the face necessarily follows, for there is no possibility of accomplishing disarticulation of the jaw without dividing many branches of the portio dura.
The distribution of the stages of disarticulation seems to fit almost exactly the pattern that one would expect if this interpretation is correct.
This would account for the first sign of decomposition and disarticulation being just back of the head.
In many specimens the head and anterior half of the body are completely disarticulated, while the posterior part of the body shows no disarticulation whatever.
For convenience, these were classified into six groups, group I showing no discernable disarticulation and group VI (Fig.
Lateral disarticulation must necessarily sever the attachment of one of the common collateral ligaments.
Patellar disarticulation may be more practically considered as momentary and fixed, regardless of the position taken by the patella.
As a rule, complete disarticulation immobilizes the affected joint and in most instances there is noticeable an abnormal prominence in the immediate vicinity--in patellar luxation, the whole bone.
In valuable breeding animals, owners may prefer that treatment be attempted when a lateral luxation and detachment of but one common ligament have permitted luxation without complete disarticulation and rupture of the joint capsule.
In temporary luxations, disarticulation is but momentary and spontaneous reposition always results; while a fixed luxation does not reduce spontaneously but remains luxated until reposition is effected by proper manipulation and treatment.
The deep cotyloid cavity renders disarticulation difficult and luxation does not often take place.
The manner of construction of the fetlock joint is such that disarticulation without irreparable injury resulting, is practically impossible.
Described under the title of false luxation are recorded cases wherein the quadriceps (crural) muscles become contracted in such manner that a condition simulating true disarticulation of the patella obtains.
