Electro-physiology and electro-therapeutics : showing the best methods for the medical uses of electricity / By Alfred C. Garratt.

nerve passes down the outer side of the leg, supplying the skin and fascia on its way to the dorsum of the foot, where it ramifies the integuments as its ultimate distribution. The anterior tibial nerve branch passes down beneath the exten- sor communis digitorum, passes under the annular ligament at the instep, supplies the adjoining sides of the great and second toes; it also gives twigs to the interossei muscles on the outer dorsum of the foot, and to the articulations of the tarsus and metatarsus. The musculo-cutaneous branch (mark !) passes down over the fibula in the substance of the peroneus longus muscle, but at the lower third of the leg it emerges, and branches superficially ; one of these goes to the top of the foot, and then to the toes, passing in front of the outer ankle bone. In fact, this branch divides on the top of the foot; one branch then subdivides, to supply three and a half toes, and the other branch one and a half. Now, to sum up what we learn from clinical experience, as well as from anatomy, and by comparing, we find in this region the neuralgic spots to be, first, at the exit and ultimate rami- fication of the nervi glutei on the side of the hip, and where many lumbar branches also terminate, which pain is very often mistaken for rheumatism, or some affection seated in the great sciatic nerve trunk. Next, a neuralgic spot is found about the tuberosity nf the ischium. Next, is the most remarkable neuralgic spot of all, which is about half ivay betioeen the ischium and the trochanter major; and this point, we know, is over the emerging spot of the great Fig- 82- A view of j . , tie Anterior Tibial ischiatic nerve trunk, and is the more usual Nerve. 1.
