Motion measurement of early HD diagnosis in the puppy/young dog

Goal of the early HD Diagnosis

  1. Since the common veterinary has no way of performing motion measurements and hence can not display movement patterns. We offer the opportunity for dog owners to get an early diagnostic evaluation regarding the status of the hip as young as the 16th week of age . This is important because a conspicuous movement pattern can hint to HD. Using motion measurement and subsequent X-Ray diagnostics, a precise assessment regarding HD can be made. In case a "positive" finding of HD is made, there is a therapeutic solution for this problem! I will provide you with more info on this matter in a separate newsletter.
  2. Another important aspect of the early HD diagnosis pertains to the training of work dogs for the police, the military, blind schools and Redog, etc. Targeted selection permits focusing on the dogs efficient and professional development.

 

HD (hip joint dysplasia) is a difficult topic, especially when it comes to the cause of this matter. It is an established fact, that the cause has a genetic component, which is a polygenic inheritance. This means that several genes play a role, and these are classified into main and secondary genes. In addition to the genetic components, environmental factors are also involved in the inheritance of the HD. Thus, the disease of the HD is a polygenic, multifactorial disease. It is obvious that the diet as well as exercise are among the most important environmental factors. This is precisely why controlling the movement is imperative, especially during the 12th to 20th week of life, as the most the important development of the acetabulum takes place during this period.

 

 

 

 

 

 

 

  

Please note the following:

The red dots are the values of the patient "F"

The yellow dots are the values of a healthy dog

 

AL: front left   AR: front right
PL: rear left   PR: rear right
BF: spine front   BP: spine rear

 

 

 

 

In the  standing and the tangential X-Rays of patient "F", we see an optimal canopy as well as a compact and stable hip joint. The kinetic values of the front and rear limbs represent the normal distribution of 60:40, which means the force is evenly distributed with 30% per front limb and 20% per rear limb. These criteria were met by patient “F”. The HD / ED evaluation in the patient "F", one year later, resulted in A / A for the hip and 0/0 for elbow. This is visible in the evaluation below.

 

 

 

 

With patient "G", the situation is different. Although the bodymass index is similar, the movement pattern is different. The hind leg, especially the left hind leg, is turned inwards and shows instability, and the valgus malalignment in the left leg is striking. The kinetic parameters also show a clear difference. Above all the force absorption is changed with 15% and 17% respectively. This is an indication of problems with the hindquarters. The kinetic results are supported by the X-Rays. The canopy of the hip can be considered normal, but the connection between the hip-joint and femoral head is too loose, which can be considered an HD problem. The "looseness" of the joint results in considerable friction during movement, which leads to arthrosis. The "looseness" of the hip joints thus explains the conspicuous movement pattern.

 

 

 

 

 

 

Please note the following:

The red dots are the values of patient "G" above

The yellow dots are the values of a healthy dog

 

AL: front left   AR: front right
PL: rear left   PR: rear right
BF: spine front   BP: spine rear

 

 

 

 

Summarizing, the following can be ascertained:

Each puppy should have a check up beginning at the 12th week of life, especially when the puppy shows a conspicuous movement pattern, with knock knees, "Charlie Chaplin" style running, buckling of the hind legs, considerable instability of the hindquarters, as well as "walking like a duck". Through early HD diagnostics with kinetic measurements, as well as standing and tangential X-Ray diagnostics, HD problems can be displayed starting as early as the 16th week of life and specific therapeutic interventions can be applied like"symphysiodesis" or "pelvic osteotomy". The latter was mentioned in my last newsletter. I will present Symphysiodese in the upcoming newsletter.

Payment and tariff

Your pet is of most importance. To maintain this, we would like to draw your attention to our direct payment.

Payments are by cash, Maestro (debit card), Postcard and credit cards accepted.

 

 

We comply with the tariff recommendations of the Swiss Society of Veterinarians (GST). The costs are based on the time that we need for your dog / cat, as well as to the nature and extent of examination and treatments that we have to perform. We like to discuss with you the costs before the examination so that you can decide which tests and treatments you want.
