Reduction of post-traumatic osteoporosis after external fixation of tibial fractures.

Disuse osteoporosis following tibial fractures is associated with pain and prolonged rehabilitation. In a prospective study, 22 patients with stable tibial fractures treated in plaster of Paris were compared with 15 patients in whom unstable tibial fractures were treated by external fixation. All patients were allowed to bear full weight from the day after the injury. The patients treated with plaster of Paris had the less severe fractures but still had a greater number of the higher grades of osteoporosis. We found a significantly lower degree of osteoporosis in the external fixator group. A comparison of the median percentage bearing weight in the two groups of patients showed greater percentage bearing weight in the external fixator group at four and eight weeks after the injury. We suggest that the reduction of post-traumatic osteoporosis is due to improved early function and weight bearing in patients treated by external fixation.

Technical note: femoral angiography using the reverse shuffle technique.

We report our findings using the "reverse shuffle" technique of stepping table femoral angiography. This technique represents a simple modification of the conventional stepping table sequence entailing a reverse table movement allowing acquisition of early and late films in the distal positions. It was developed in order to minimize the number of runs required in each examination. In a retrospective study 52/53 (98%) of angiograms using the reverse shuffle technique required only a single run compared with 30/51 (58%) using the conventional technique. We believe that the reverse shuffle should be used where possible when stepping table angiography is performed. Furthermore, the incorporation of a reverse table movement may also be advantageous in angiography using automated digital subtraction angiography (DSA) stepping systems.
