We report 33 cases of femoral supracondylar fracture in elderly or debilitated patients treated by Zickel supracondylar nails. Most of the patients were female and their mean age was 79 years. All had concurrent medical problems and only nine could walk unaided. The operating time averaged one hour and mean blood loss was 100 ml. Postoperative management was by mobilisation in a cast brace or plaster. Six patients died before fracture union; all the others achieved union at an average of 12 weeks. The results were excellent in terms of pain relief, movement and function; there were no infections or nonunions. The locking screws backed out or broke in 26% but this did not prejudice the outcome. Use of the Zickel system is recommended for this group of frail patients.

We have undertaken routine ultrasound screening for neonatal hip instability in Coventry since June 1989. Of the 14,050 babies scanned during the first three years, 847 (6%) had ultrasound abnormalities. A grading system, based on the percentage of femoral head coverage, is presented. The proportion of abnormal hips decreased gradually so that by nine weeks, 90% had normal ultrasound appearances. Abnormality was more common in babies with a family history of CDH and in breech presentations. All babies with clinically abnormal hips had an abnormal first ultrasound examination. Five babies not diagnosed by clinical examination and with no risk factors had abnormal ultrasound appearances and were subsequently found to have clinically abnormal hips. Routine ultrasound screening has detected cases which would otherwise have presented late.
