PennHIP Evaluations & OFA

What are PennHIP Evaluations?

PennHIP (PennHIP) evaluations are a type of hip evaluation that is used to assess the risk of hip dysplasia in dogs. Hip dysplasia is a common condition in dogs that can lead to pain, arthritis, and mobility issues.

PennHIP evaluations involve taking specialized radiographs (x-rays) of a dog’s hips to measure the amount of laxity or looseness in the hip joint. This measurement, known as the distraction index, is a key indicator of a dog’s risk for developing hip dysplasia. The radiographs are taken under sedation or anesthesia to ensure the dog is comfortable and still during the procedure.

The technique assesses the quality of the canine hip and quantitatively measures canine hip joint laxity. The method is quantitative (i.e., it assigns a number to joint laxity) as opposed to being qualitative or subjective (e.g., excellent, good, fair, etc.). 

The PennHIP evaluation process involves three steps:

  1. Radiographs: Radiographs are taken of each hip, one with the femur in a neutral position and another with the femur in a maximally extended position.
  2. Image analysis: The radiographs are analyzed by trained PennHIP evaluators who calculate the distraction index based on the measurements taken from the radiographs.
  3. Report: A report is generated that includes the distraction index, as well as information on the dog’s breed, age, and weight.

The PennHIP evaluation is considered to be one of the most accurate methods for predicting the risk of hip dysplasia in dogs. It allows veterinarians and breeders to identify dogs that may be at risk for hip dysplasia and take preventive measures, such as dietary and exercise changes, to reduce the risk of developing the condition. It also helps breeders to make informed decisions about breeding stock, to reduce the incidence of hip dysplasia in future generations.

What is Hip dysplasia?

Hip dysplasia is a genetic condition that affects the hip joints of dogs. It occurs when the ball and socket of the hip joint do not fit together properly, which can lead to instability, pain, and degeneration of the joint over time.

The condition is most commonly seen in large and giant breed dogs, but can also occur in smaller breeds. It is thought to be caused by a combination of genetic and environmental factors, including rapid growth, obesity, and nutritional factors.

Hip dysplasia can cause a range of symptoms, including:

  • Stiffness and lameness in the hind legs
  • Difficulty rising from a lying or sitting position
  • Reduced activity and exercise tolerance
  • Pain and discomfort when walking or running
  • Loss of muscle mass in the hindquarters
  • Clicking or popping sounds when walking

Hip dysplasia can be diagnosed through a physical examination, radiographs (x-rays), and other diagnostic tests. Treatment options depend on the severity of the condition and may include weight management, exercise modification, pain management, and surgery.

Prevention of hip dysplasia involves responsible breeding practices, such as screening potential breeding stock for the condition through methods like the PennHIP evaluation, as well as providing appropriate nutrition and exercise for growing puppies. Regular veterinary check-ups and early intervention can also help to manage the condition and improve the quality of life for affected dogs.

OFA– The Canine Health Information Center

The OFA (Orthopedic Foundation for Animals) is a non-profit orthopedic veterinarian organization that collects and disseminates information on canine genetic diseases, with a focus on orthopedic and genetic diseases that affect dogs.

The benefits of the OFA program for veterinarians and their patients include:

  1. Access to valuable health information: The OFA program provides a centralized database of health information for participating dogs, which can help veterinarians to make informed decisions about breeding, diagnosis, and treatment.
  2. Improved patient care: By participating in the OFA program, veterinary hospitals can provide better care for their patients by identifying potential genetic health problems early and developing appropriate treatment plans.
  3. Enhanced reputation: Veterinary hospitals that participate in the OFA program demonstrate their commitment to responsible breeding and high-quality patient care, which can enhance their reputation and attract new clients.

In summary, the OFA and CHIC programs provide valuable resources and tools for veterinary hospitals to improve patient care, access important health information, and demonstrate their commitment to responsible breeding and high-quality veterinary medicine.
