Intramedullary nailing of the femoral shaft: a prospective, randomized study.

We conducted a prospective, randomized study on 84 consecutive patients with 88 acute, traumatic femoral shaft fractures using 32 Grosse-Kempf nails, 29 Russell-Taylor nails, and 27 Synthes nails. Although total operative times and proximal and distal locking times were similar for the three groups, the procedure was faster with the Grosse-Kempf nail. Three proximal fractures could not be locked with the Synthes nail. At first follow-up, we found no significant difference in terms of pain, limp, range of motion, or time to union; however, we removed fewer Synthes nails to resolve patient complaints of pain. Three delayed unions were attributed to fracture distraction. We conclude that all three nails are suitable for the treatment of almost all femoral shaft fractures. A careful analysis of intraoperative technique and instrumentation indicates that all three nails can be used safely and easily once experience is gained. Clinical outcome is similar regardless of the nail chosen.

Transvaginal sonography of the endometrium in postmenopausal women.

The purposes of this study were to compare transvaginal sonographic scanning of the uterus and endometrium with histology obtained by endometrial biopsy or curettage and to determine whether the sonographic technique might be useful in the evaluation of postmenopausal women. Eighty postmenopausal women were studied. Of these, 65 were asymptomatic (38 on no hormone therapy and 27 on hormone replacement). Fifteen women underwent evaluation because of postmenopausal bleeding. In both groups, endometrial thickness of 4 mm or less as depicted by sonography correlated well with endometrial characteristics of decreased estrogen stimulation. However, in women with measured endometrial thickness between 5-8 mm, proliferative endometrium could not be distinguished from hyperplastic endometrium or, in one case, low-grade carcinoma. Large polyps and invasive carcinoma with myometrial extension were easily recognized.

Intravitreal injections by a Dermojet syringe.

Dermojet is a spring-loaded device that injects a high velocity microspray capable of perforating the globe. An accidental intraocular injection of triamcinolone acetonide from a Dermojet syringe by a dermatologist is reported. The lack of untoward effects led to experimental intravitreal injections. The Dermojet syringe was used for intravitreal injections in 7 rabbit eyes with normal saline as the vehicle in 6 and India ink in one. There were no irreversible effects attribute to the injection noted clinically or histopathologically. While modification and further animal experimentation with this device are in order, it should not be use on human eyes at this time.
