Upper extremity arthrography.

Arthrography is a proven and well-established diagnostic aid in the evaluation and treatment of lesions in several joints; it provides useful information in the treatment of shoulder and wrist lesions. The procedure can be used whenever the cause of shoulder pain is in doubt. Arthrography of the shoulder can aid in the diagnosis of a variety of lesions: rotator cuff tear, subluxation of the shoulder, recurrent dislocation, subluxation and tear of the biceps tendon, the frozen shoulder, anterior capsular derangements, and combinations of these abnormalities. Arthrography has occasional, but definite use in the wrist, particularly in recurrent ganglion, painful ganglion on the flexor aspect of the wrist, and in the evaluation of the post-traumatic wrist with unexplained pain.

Antibiotics in human hematoma and wound fluid.

Using the total hip replacement patient, we measured the level of antibiotic in the wound at the time of surgery, the wound drainage for 36 to 48 hours after surgery and over a 10 day period in incubated surgical debris obtained at the time of total hip replacement. The antibiotics sodium oxacillin, lincomycin hydrochloride and sodium cephalothin were administered in standard doses at 6 hour intervals. In one group of patients the antibiotic was begun at the time of surgery, in a second group the antibiotic was begun 24 hours after the completion of surgery. Sodium oxacillin, lincomycin hydrochloride and sodium cephalothin produce antibiotic levels in the venous serum consistently above the level obtained in the simultaneous would drainage specimens. Sodium oxacillin and lincomycin hydrochloride used as described in this study are capable of bathing the area of the surgical wound with concentrations of antibiotics above the minimal inhibitory concentrations. This is evidenced by the antibiotic levels above minimal inhibitory concentrations found in the wound drainage. Sodium cephalothin levels in the wound drainage were below measurable levels in 3 of 4 patients. Sodium oxacillin and lincomycin hydrochloride antibiotic levels in the surgical wound debris and simultaneous venous clotted specimens diminished progressively in a similiar manner indicating no additional effects of the surgical wound debris on the antibiotic's biologic effectiveness. Sodium cephalothin dropped below measurable levels in three days. Measurable levels of antibiotics appeared in the wound aspirate well above the minimal inhibitory concentration in patients receiving their initial dose of sodium oxacillin 24 hours after surgery.

Longitudinal amputation for the treatment of soft tissue fibrosarcoma.

Methods of treating fibrosarcoma are difficult to assess because of the slow growth and relative infrequency of the tumor and individual variability. Longitudinal amputation, a method of complete origin to insertion compartmental excision of a soft tissue fibrosarcoma, is presented along with a discussion of indications, contraindications, and surgical technique.
