PURPOSE: To evaluate the functional status after Gamma nailing in inter-trochanteric fractures in elderly with functional recovery score (FRS). MATERIALS AND METHODS: We reviewed 285 patients of intertrochanteric fracture treated by gamma nailing from January 1993 to May 2002 with follow up more than 3 years. We analized recovery of functional status concerned with sex, age, fracture pattern, functional recovery index. RESULTS: The intertrochanteric fractures in elderly resulted in 15.8% loss of function after 3 years. The more functional loss was observed in female, the older age, and Boyd-Graffin type II fracture but, were not signifily related with functional loss except age. CONCLUSION: We concluded that the age is the important factor to functional recovery to pre-injury status in elderly patients.
