Factors affecting lumbar spinal fusion.

There is little information on the effect of nonsurgical factors or postoperative anemia on achieving spinal fusion. In a prospective cohort study of 184 consecutive lumbar spinal fusions, we obtained data on socioeconomic, clinical, radiologic, and traditional surgical factors and analyzed associations between these factors and fusion status at 6 months post surgery. The overall fusion rate was 74%. Among the surgical factors, use of pedicle screw fixation (p = 0.005) predicted fusion success; postoperative anemia (hematocrit < 30%; p = 0.003) and a history of smoking (p = 0.050) predicted fusion failure. However, when the surgical factors were analyzed together with clinical and socioeconomic factors, back pain greater than or equal to leg pain (p < 0.001) and patients working at the initial visit (p = 0.001) predicted fusion success; shoulder pain at the initial visit (p < 0.001) and a family history of back surgery (p = 0.006) predicted fusion failure. These factors were stronger predictors of fusion status than were traditional surgical factors.

Ulnar variance in Kienböck's disease.

The distal extent of the radius and ulna (ulnar variance) was compared on roentgenograms of normal wrists in randomly selected black and white patients and of fifteen affected wrists in patients with Kienbock's disease. The results establish a statistically significant association between negative ulnar variance and Kienbock's disease. Blacks have more positive ulnar variance and the disease is less likely to develop in them than in whites.

High-pressure injection injuries of the hand.

In high-pressure injection injuries to the hand the most commonly injected materials are automotive grease, diesel oil, and paint. We treated twenty-six patients with high-pressure injection injuries of the hand and found that the injection of paint resulted in a poorer prognosis than did the injection of grease. Amputation is often necessary with paint injections into a digit, while injections into the palm have a somewhat better prognosis. The disability time of patients with paint-injection injuries appeared to be directly related to the time elapsed until amputation of the involved digit. Although we were unable to specifically relate the ultimate result to the time elapsed between injury and proper treatment, we continue to recommend early aggressive wide débridement of these injuries.
