![]() ![]() This information is accepted by AKC on dogs with permanent identification and is in the public domain. ![]() The hip grades of excellent, good and fair are within normal limits and are given OFA numbers. Significant arthritic bone changes along the femoral neck and head and acetabular rim changes. The ball is partly or completely out of a shallow socket. Severe: Marked evidence that hip dysplasia exists.There are secondary arthritic bone changes usually along the femoral neck and head (remodeling), acetabular rim changes (osteophytes or bone spurs) and various degrees of trabecular bone pattern changes Moderate: The ball is barely seated into a shallow socket.The socket is usually shallow only partially covering the ball. Mild: Significant subluxation present where the ball is partially out of the socket causing an increased joint space.Usually more incongruency present than what occurs in a fair but there are no arthritic changes present that definitively diagnose the hip joint being dysplastic. The socket may also appear slightly shallow. ![]() The ball slips slightly out of the socket. Fair: Minor irregularities the hip joint is wider than a good hip.The ball fits well into the socket and good coverage is present. Good: Slightly less than superior but a well-formed congruent hip joint is visualized.Excellent: Superior conformation there is a deep-seated ball (femoral head) that fits tightly into a well-formed socket(acetabulum) with minimal joint space.The OFA classifies hips into seven different categories: Excellent, Good, Fair (all within Normal limits), Borderline, and then Mild, Moderate, or Severe (the last three considered Dysplastic). ![]()
