Kim, Park, and Yoon: The Result of Total Hip Arthroplasty after Failure of Multiple Screw Fixation for Femoral Neck Fracture

Abstract

Purpose

The purpose of this study is to analyze the result of secondary total hip arthroplasty (THA) after primary internal fixation failure in femoral neck fracture patients and compare the results with primary THA for femoral neck fracture.

Materials and Methods

Among the femoral neck fracture patients, we analyzed clininal and radiologic results of those who underwent secondary THA after internal fixation failure and those who underwent THA as early treatment. Cases with patients over age 40 years and with at least two year of follow-up period were used for analysis. Periopertive conditions of patients were evaluated by using surgery time, bleeding amounts and period to start gait using walker or crutch after surgery. Clinical results were assessed by using Harris hip score and Western Ontario and McMaster Universities Osteoarthritis Index, and radiologic results were derived by observing follow-up simpe X-ray.

Results

The group of secondary THA had longer surgery time, more bleeding amount and longer period to start gait. But between the two groups, there was no difference of clinical and radiologic result at final follwing up. Both of two group had excellent clinical and radiological results.

Conclusion

THA after internal fixation showed excellent clinical and radiologic results that was comparable to compare with primary THA.
