The reliability of a Garden, AO and simple II stage classifications for intracapsular hip fractures.

Introduction: Successful treatment starts by accurate classification of pathology, but there is no conclusive, reliable and universally accepted method for classification of intracapsular femoral neck fractures. As a perfect classification should have high intra- and interobserver agreement, this study aims to access reliability of three classification systems: Garden, AO and simple II stage classification.

Materials And Methods: Four orthopaedic trauma surgeons (two of them professors) and two senior orthopaedic trauma residents were invited to evaluated 136 blinded anterior-posterior and lateral X-rays of patients with femoral neck fractures.
