French Bulldogs & English Bulldog Hip Joint Laxity, HD, CHD, OA, DJD

French Bulldogs & English Bulldog Hip Joint Laxity, HD, CHD, OA, DJD Introduction

French Bulldog & English Bulldogs Canine Hip Dysplasia Disease Syndrome in its severest form can be diagnosed by clinical signs, but it usually requires radiographic evidence of bulldog hip joint laxity & the appearance of bulldog degenerative joint disease to arrive at a definitive diagnosis. Clinical signs of French Bulldog & English Bulldogs Canine Hip Dysplasia Disease Syndrome are not by themselves Hip Dysplasia Pathognomonic Signs in French Bulldog & English Bulldogs, other conditions of the hip can mimic bulldog hip dysplasia. A radiograph is essential for a more accurate assessment of the French Bulldog & English Bulldog's hip joint integrity. Anyway affected French Bulldog & English Bulldogs may have one or any combination of the following clinical signs: French Bulldog & English Bulldogs the Presentation of Canine Hip Dysplasia Disease Syndrome occurs between 5 months to 12 months for the severe form of bulldog hip dysplasia; later for the chronic form. French Bulldog & English Bulldogs are showing Pain an Abnormal Gait & Bunny-hopping when Running. French Bulldog & English Bulldogs highlight Thigh Muscle Atrophy, loss of muscle mass. French Bulldog & English Bulldogs appear affected by Low Exercise Tolerance & Reluctance to Climb Stairs. Sometimes is Audible "click" When French Bulldog & English Bulldogs are Walking.

Comparison of two radiographic techniques for evaluation of hip joint laxity in 10 breeds of dogs

Department of Clinical Studies, School of Veterinary Medicine, University of Pennsylvania, Philadelphia, PA 19104-6010, United States of America:

OBJECTIVE:

To evaluate hip joint laxity in 10 breeds of dogs via 2 radiographic techniques. ANIMALS: 500 clinically normal dogs.

DESIGN:

Prospective study.

PROCEDURE:

Radiographs obtained via routine hip joint evaluations performed in sedated dogs of 10 popular breeds were randomly selected from a database. Measurements of distraction index (DI) and hip-extended index (HEI) on 1 hip joint radiograph randomly chosen from each dog were made.

RESULTS:

Mean age of dogs was 20.7 months. Mean HEI was 0.17 (range, 0.0 to 0.72) and mean DI was 0.44 (range, 0.07 to 0.96). Borzois had uniformly tight hip joints as judged by use of both methods and were considered the gold standard by which hip joint laxity was judged (all Borzois had DI < or = 0.32). Overall, DI was significantly greater than HEI. Within each breed, mean DI was always greater than mean HEI. Significant differences were detected among breeds for HEI; however, compared with DI, the magnitude of differences among breeds was less.

CONCLUSIONS AND CLINICAL RELEVANCE:

Distraction radiography detected the greatest range and magnitude of passive hip laxity in the 10 breeds of dogs. The difference in values between breeds known to have high prevalence of canine hip dysplasia and those in Borzois was greater for DI than for HEI. Breeds must be evaluated individually because of inherent differences in hip joint laxity.

Bulldog Congenital Predispositions: Bulldogs Joint Laxity, Bulldogs Degenerative Disease, Bulldogs Osteoarthritis

Laboratory for Equine and Comparative Orthopedic Research, Department of Veterinary Clinical Sciences, School of Veterinary Medicine, Louisiana State University, Baton Rouge, LA 70803, United States of America.

OBJECTIVE:

To assess relationships of acetabular volume (AV), femoral head volume (FV), and portion of the femoral head within in the acetabulum (FVIA) with each other and with degrees of hip joint laxity and degenerative joint disease from youth to maturity in dogs predisposed to developing hip joint osteoarthritis (OA).

ANIMALS:

46 mixed-breed half- or full-sibling hound-type dogs.

PROCEDURES:

The distraction index (DI), AV, FV, FVIA, and degree of osteoarthritis (OA score) were quantified in 1 hip joint at 16, 32, and 104 weeks of age. Relationships among variables were evaluated within and between ages. Ratios corresponding to OA scores were compared within ages. Differences among 16-week ratios corresponding to 32-week OA scores and among 16- and 32-week ratios corresponding to 104-week OA scores were evaluated.

RESULTS:

Significant positive relationships existed between FV and AV across ages as well as between FVIA/FV and FVIA/AV and between DI and OA score across and within most ages. Such relationships also existed within these variables across most ages. Negative relationships of DI and OA scores with FVIA/FV and FVIA/AV within and among all ages were significant. Sixteen-week AVs, FVs, and FVIAs were greater and FV/AVs and OA scores were less than 32- and 104-week values. The 32-week FVIA/FV was less than 16- and 104-week values, and the 32-week FVIA/AV was less than the 104-week value. The FVIA/FV and FVIA/AV were lower and the DI was higher with higher OA scores within and among most ages.

CONCLUSIONS AND CLINICAL RELEVANCE:

Structural volumes in lax canine hip joints changed predictably relative to each other during growth, despite degenerative changes. Measures developed in this study may augment current diagnosis and treatment strategies for hip dysplasia in dogs.
