External fixator in the management of trochanteric fractures in high risk geriatric patients--a friend to the elderly.

ABSTRACT

The best treatment option for trochanteric fracture in a geriatric high risk patient with all associated medical and surgical problems remains debatable. Conservative methods of treatment are associated with dangerous complications of prolonged recumbency while open reduction and internal fixation under anaesthesia significantly increases the mortality and morbidity rates. We treated 110 elderly patients who were unfit or high risk cases for anaesthesia and major surgery for internal fixation due to associated medical and surgical conditions, by external fixation under local anaesthesia. The average age was 65 years and mean follow up was 18 months. 83.3% were ambulatory with support and 97.2% were able to manage activities of daily living at the time of discharge. At 18 months post surgery, 74% were ambulatory with a stick or better. The fracture united in an average of 16.4 weeks. Overall satisfaction rate was 80% at end follow up. The mortality rates were comparable to series of open reduction and internal fixation. Pin tract infection and knee stiffness were the major complications. External fixation done under local anaesthesia offers advantages in the form of a quick, simple relatively inexpensive procedure with negligible blood loss, preserves fracture haematoma, can be easily removed as an out patient procedure, besides it provides earliest possible ambulation and day care to the elderly high risk patient.
