In 330 consecutive anesthetics administered over a period of 24 months, an improved method of upper extremity intravenous regional anesthesia, entitled "the second wrap technique," included wrapping the extremity a second time with a Martin rubber bandage after the extremity was prepared and draped. In addition, a Penrose drain tourniquet often was applied during injection of the 0.5% lidocaine. ⋯ The technique provides a nearly bloodless operative field, improves the anesthesia, diminishes tourniquet pain, lessens the contraindications, and requires no premedication. The only contraindications are allergy to lidocaine, infection, operating time over 2 hours, and severe hypertension.

Two patients with irreducible dislocation of the distal interphalangeal joint underwent surgical exploration. In each patient the volar plate, having been disrupted proximally, was trapped between the joint surfaces, preventing closed reduction.

Two new cases of atypical mycobacterium infections of the deep structures are reported. With two reported previously by the authors and a review of 24 others recorded by others, the symptoms and signs are reviewed. Typically it occurs in the middle-aged person, some of whom give a history of a puncture wound within 6 weeks of onset of symptoms. ⋯ Fever does not occur and no systemic signs are present. Biopsy and cultures are essential for diagnosis, but a presumptive diagnosis indicates that, after synovectomy, treatment should be started with antituberculous drugs, isoniazid with ethambutol, Rifampin, or both and continued for 18 to 24 months, unless in vitro sensitivity tests indicate a change of medication. The usual organisms are M. kansasii, M. marinum, M. intracellulare, and M. avium.
