Functional index: a numerical expression of post-traumatic wrist function.

Accurate functional assessment is an essential part of the analysis of managing fractures. A new technique for the measurement of the wrist's function is described. Observations of a wrist's performance are made using three devices. A dynanometer records movement while acting against a resistive torque. Angular and rotational movement at the wrist is measured using a three-dimensional goniometer. A vigorometer is used to assess the strength of grip. The three derived measurements give a functional index for each patient. Eighty-nine patients sustaining fractures at the wrist were seen at the time of trauma and at an assessment clinic 6 months later. Statistical analysis has shown that all three measurements are necessary to assess function. A functional index has applications in clinical work and research.

Starch synovitis.

Three patients with unexplained synovial inflammation were found to have an ulcerative, granulomatous synovitis on biopsy. Maize starch was identified in giant cells within the granulomata. Starch synovitis has clinical and histological similarities to starch peritonitis, which is thought to be an example of a cell mediated immune response.

Fetal pulse oximetry: an adjunct to electronic fetal heart rate monitoring.

Electronic fetal heart rate monitoring is routinely used as an indirect measure of fetal oxygenation, yet its value continues to be questioned. With a nonreassuring fetal heart rate pattern, the clinician often needs additional information about fetal oxygen status. Fetal pulse oximetry is a new fetal assessment technology. After consideration of the results of a multicenter randomized, controlled, clinical trial on fetal pulse oximetry in the United States, the U.S. Food and Drug Administration approved the technology for clinical use on May 12, 2000. The results of this trial are anticipated to be published in late 2000.
