2. Tenotomy of the extensor tendon (Boyer). This measure, which was doubtless suggested by the visible tension of the tendon in many cases, is more likely to aggravate than to relieve the symptoms. 3. Tenotomy of the flexor tendons. This to be successful must involve also the section of the glenoid and lateral ligaments. Such an operation has been practised both by the subcutaneous and by the open methods, but it involves the risk of division of the plantar digital nerves, and the necessity for a prolonged after-treatment to prevent recurrence. It has even been advised by Petersen to treat the contraction by a transverse incision, through integuments, tendons, and ligaments, down to the articulation, but the promptitude of the method is its sole recommendation. 4. Subcutaneous division of the lateral ligaments has been performed with good results by Mr. Adams, but it has the disadvantage of requiring a long after-treatment. 5. Resection of the joint. This is unquestionably the most eligible measure, and has been successfully practised on different plans by various surgeons during the last twelve years or more, both in England and France. The articular extremities of both bones may be removed or the head of the proximal bone only, the distal bone being left intact. In either case the toe is subsequently fixed for a period of three or four weeks in an extended position. The procedure I have found most speedy and satisfactory is as follows: An incision is made on the lateral aspect of the affected articulation, following the axis of the bones and exposing the lateral ligament, while leaving intact the vascular and nervous trunks. The ligament is then divided, by a touch of the knife, and by a forcible lateral movement the head of the proximal phalanx is made to protrude through the wound, and is removed with a pair of bone nippers. The toe is straightened, the wound closed by sutures (without drainage), and dressed. Antiseptic precautions must be strictly observed, and the operation must not be performed until all inflammatory signs have been removed from the superjacent corn. The operation can be completed within two or three minutes, and, what is a far more important consideration, it involves the least possible interference with the structures of the toe. The wound heals by first intention, and after a fortnight’s rest the patient is able to walk, the toe being extended for a few weeks upon a dorsal splint of flat steel, such as was used in making the now obsolete appendages to the back of the feminine skirt. The result is all that could be desired, and the relief immediate and permanent. The same operation is applicable for the distal joint, but is less easy.
