Abstract

Purpose

To review the outcome of high-risk geriatrics with unstable pertrochanteric fractures treated with external fixator.

Methods

Eighteen consecutive patients with pertrochanteric fractures were operated with external fixator by using closed reduction technique. AO type, accompanying diseases, operating time, transfused blood units, duration of hospitalization, complications, healing time and mortality were recorded. Patients were followed clinically and radiologically for two years at least. The Harris Hip Score was used to document hip function at each regular follow-up.

Results

Fifteen patients with average age of 71.5 years were available for final evaluation. The mean operating time was 41.1 min and union was achieved in all cases with an average time of 16 weeks. The mean Harris Hip Score at one, three, six, twelve and twenty-four months post-operatively was 42.07 ± 8.55; 55.07 ± 11.62; 70.07 ± 10.32; 86.27 ± 9.06 and 89.27 ± 8.81 respectively. Complications included all the patients undergoing loss of some motion in the knee and four of them had to experience revision surgery because of knee stiffness, ten cases of pin-tract infections, seven cases of deep venous thrombosis, two cases of migration of the screws and two cases limb shortening.

Conclusions

The use of external fixator in high-risk geriatric provided a satisfactory long-term efficacy, but the short-term functional results were quite unsatisfactory owing to high complication rate. Therefore, the advantages and disadvantages should be fully weighed when using external fixators, which was especially suitable for those patients who could not tolerate prolonged operative time and open surgery.
