Impact of organisational changes on fracture neck of femur management.

INTRODUCTION: In 2005, University Hospitals of Leicester formed a Fracture Neck of Femur (#NOF) project group to improve care of this group of patients. SUBJECTS AND METHODS: The salient changes effected by the group were the appointment of designated orthogeriatricians, trauma co-ordinators, clinical aides, and discharge nurses. RESULTS: As a result of these measures, the number of patients going to theatre within 48 h of admission rose from 38.5% in 2005/6 to 90% in 2007/8. In-hospital mortality decreased from 16.5% in 2005/6 to 10.9% in 2007/8. The 30-day mortality dropped from 13% in 2005/6 to 10.9% in 2007/8. Hospital stay reduced from 29 days in 2005/06 to 17 days in 2007/8. CONCLUSIONS: Re-organisation of available resources has a positive impact on reducing mortality and in-hospital stay of fracture neck of femur patients.

Dynamic ultrasound assessment of the effects of knee and ankle position on Achilles tendon apposition following acute rupture.

BACKGROUND: Previous reports have suggested that knee flexion improves tendon edge apposition following acute rupture of the Achilles tendon. The aim of the present study was to determine, with use of ultrasonography, the effects of knee and ankle position on the Achilles tendon gap distance in patients with an acute rupture. METHODS: Twenty-six patients with a unilateral acute complete Achilles tendon rupture that had been confirmed with ultrasonography were recruited within a week after the injury. The mean age at the time of presentation was forty-one years. Ultrasound measurements included the location of the rupture and the gap distance between the superficial tendon edges with the ankle in neutral and the knee extended. The gap distance was sequentially measured with the foot in maximum equinus at the ankle and with 0°, 30°, 60°, and 90° of knee flexion. RESULTS: The mean distance of the rupture from the calcaneal enthesis was 52 mm (range, 40 to 76 mm). The mean gap distance with the ankle in neutral and the knee extended was 12 mm (95% confidence interval, 10 to 13 mm). This distance decreased to 5 mm (95% confidence interval, 4 to 7 mm) when the foot was placed in maximum ankle equinus with 0° of knee flexion and to 4 mm (95% confidence interval, 3 to 5 mm) with 30° of knee flexion, 3 mm (95% confidence interval, 2 to 4 mm) with 60° of knee flexion, and 2 mm (95% confidence interval, 1 to 2 mm) with 90° of knee flexion. Expressing the reduction in gap distance with each successive position as a percentage of the gap distance with the knee extended and the ankle in neutral revealed a mean reduction of 55.7%, 64.4%, 75.4%, and 84.8% with maximum ankle equinus and 0°, 30°, 60°, and 90° of knee flexion, respectively. The difference in gap distance between each of these positions was significant (p < 0.05). CONCLUSIONS: Maximum ankle equinus alone significantly reduces the gap distance after acute Achilles tendon rupture. Increasing knee flexion further reduces the gap distance by small increments that, although significant, may not be clinically important.

What follow-up is required for children with a family history of developmental dysplasia of the hip?

To determine what follow-up is needed for children with a family history of developmental dysplasia of the hip (DDH) but who have had a normal clinical and ultrasound examination at 6 weeks of age. A retrospective review of medical and imaging records of all children with a family history of DDH referred to the hip-screening clinic over a 5-year period. An absolute acetabular index value of greater than 30 degrees or gross asymmetry in acetabular index values was used as an indication of occult acetabular dysplasia. One hundred and eighty-one children were identified as having had a normal ultrasound scan with a positive family history of DDH. Two (1.1%) children had acetabular dysplasia on their radiograph performed at 9-12 months of age. The dysplasia, however, resolved in both cases with simple observation and both children have now been discharged from further follow-up. We do not feel that it is necessary for children with a positive family history of DDH to have a radiograph of their pelvis at 1 year of age if they have had a normal clinical and ultrasound examination at 6 weeks of age and such children can safely be discharged from further follow-up at that time.

Fractured neck of femur in a child after femoral fracture fixation by intramedullary flexible nails: a case report.

Since the introduction of flexible intramedullary nails, the treatment of femoral shaft fractures in adolescents has been revolutionized and this has become the routine treatment in most units, with minimal complications. We report a rare complication of an ipsilateral fractured neck of femur in a fit and healthy 12-year-old girl 6 months after treatment of a traumatic fractured femoral shaft; this was treated effectively with cannulated screws and the patient was successfully discharged without any further complication.
