A practical treatise on fractures and dislocations . ocations are thosein which complete disruptionof the ilio-femoral ligament hasnot taken place. The irregular dislocations arethose in which the ilio-femoralligament has suffered completedisruption. In reducing either of the reg-ular dislocations the limb mustbe flexed, in order to relax theilio-femoral ligament; but if ?other portions of the capsuleare not sufficiently torn to admit the return of the head within itssocket, it must be torn by circumduction of the limb. After flexion,and perhaps circumduction, the reduction may be completed by rota-tion, or by extension of the thigh at right angles with the anteriorsurface of the body. The dorsal dislocation owes its inversion to the external fasciculusof the ilio-femoral ligament. In the ischiatic dislocation, dorsal below the tendon (Bigelow),the head is arrested, in extension, by the tendon of the obturator andthe subjacent capsule. The flexion and eversion of the limb in the thyroid dislocation aredue to the ilio-femoral Ilio-femoral ligament. (Bigelow.) 1 Year-Book of Med. and Surg, for 1864. Sydenham Soc.

In the pubic dislocation the ascent of the limb is finally arrested bythe ilio-femoral ligament. The conclusion at which we ought to arrive seems to be that, insome cases, the capsule being completely or almost completely tornaway, the muscles offer the only resistance; and that according to the Fig. 297.
