“…Still, multiple prevalence studies showed no sex predilection [28]. Besides, clinical signs are usually evident at 4-12-month-old dogs [29]; this explains the high incidence in the group of age older than 3 months (90.91%). Nevertheless, no significant association was reported.…”

Aim: A retrospective study was undertaken to determine the occurrence, and the distribution of the most common clinical conditions of young dogs encountered at the National School of Veterinary Medicine clinic, Tunisia, from September 2012 to July 2013, based on sex, age, breeds, and season variation. Materials and Methods: A total of 515 cases were examined, and 11 clinical conditions were recorded. Clinical examination was performed. X-ray examination and necropsy were carried out only when needed. Results: Of the 515, 298 cases (57.86%) were male, while 217 (42.14%) were female. The breed-wise difference in the occurrence of various health problems was statistically significant. Nevertheless, no significant association was found between the occurrence of a disease and age. The commonly found clinical conditions were traumatic injuries (22.72%), ectoparasitic infections (20.58%), and gastroenteritis (13.40%). The occurrence of diseases was the highest (60.19%) in the wet season (September-February) followed by 39.81% in the dry season (March-July). Conclusion: The current study presents the first recorded data about the major clinical conditions of young dogs in Tunisia. These findings can be used to develop more effective disease management and control strategies.

“…Developmental dysplasia of the hip (DDH) is frequently seen in pediatric patients with neuromuscular diseases. In many cases, DDH is related with a congenital or developmental deformity or misalignment of the hip joint [ 1 ] and cerebral palsy [ 2 ]. Anatomically, DDH is characterized by a shallow acetabulum, insufficient coverage and lateral and anterior dislocation of the femoral head [ 3 ].…”

Background This retrospective study sought to delineate the radiographic characteristics of DDH patients over 13 years of age and investigate whether the lateral center-edge angle (LCEA) could serve as radiographic selection criteria for periacetabular osteotomy. Methods We enrolled patients with Hartofilakidis type I DDH without dislocation who underwent periacetabular osteotomy between August 2009 and August 2012. LCEA, anterior central edge angle (ACEA), femoral neck-shaft angle (FNSA), Shenton line and Tönnis acetabular index (AI) were evaluated by anteroposterior and 65° false⁃profile pelvic X-ray radiographs in the standing position. Femoral neck anteversion angle (FNA), labral lesion, labral inversion and cartilage lesion were evaluated by direct magnetic resonance arthrography. DDH was categorized by LCEA into four grades (grade I: 10° ≤ LCEA< 20°, grade II: 0° ≤ LCEA< 10°, grade III: -10° ≤ LCEA< 0°, grade IV: LCEA<-10) and osteoarthritis (OA) severity was assessed using Tönnis OA classification. Pearson correlation analysis was done between LCEA and other variables. Results Totally patients (274 hips) with a mean age of 27.3 years (range 13–47 years) were included. The mean LCEA was 3.5° (range: − 30° to 20°). Based on LCEA grades, grade I DDH was present in 104 hips, grade II in 40 hips, grade III in 76 hips, and grade IV in 54 hips. Based on Tönnis OA classification, 54.5% hips (150/274) were grade 0, 33.1% hips (91/274) grade 1, 8.4% hips (23/274) grade 2 and 4% hips (11/274) grade 3. Pearson correlation analysis showed a negative correlation between LCEA grade and Tönnis OA grades ( r = 0.3987; P < 0.001). Cochran-Armitage trend test further showed a positive correlation between LCEA grades and labral lesion ( P < 0.001) and interrupted Shenton line ( P < 0.001). Conclusion The LCEA classification scheme offers a simple and practical approach to categorize the level of acetabulum coverage on the femoral head, hip deformity and characteristics of DDH. Our findings could provide clinically useful guidance for orthopedic surgeons in preparation for periacetabular osteotomy in DDH patients aged above 13 years.

“…Hip dysplasia is a common orthopedic disease in the canine species 1 that normally affects large breeds, 2 potentially leading to hip pain, reduced movement, difficulty lying down or rising, and hind limb muscle atrophy compromising the quality of life of dogs 3 . The cause of canine hip dysplasia is still unknown, but it is considered a multifactorial condition where genetic and environmental factors play a significant role in its phenotypic expression 4 .…”

The Orthopedic Foundation for Animals (OFA) radiographic grading system stands as a well‐established benchmark for categorizing hip dysplasia in canines. Although more objective techniques to quantify early hip laxity in young dogs, such as the Norberg angle (NA) and distraction index (DI), have been documented, there is a scarcity of published studies that directly compare these radiographic measures. The primary objectives of this prospective, analytical study were to assess and compare the NA and DI measures with OFA grades within a cohort of dogs. Thirty dogs (57 hip joints) were evaluated, with a mean age of 5.4 ± 2.9 years and a mean body weight of 34.3 ± 7.1 kg. The discriminative power of hip dysplasia for DI and NA used OFA as a reference were compared by multivariate discriminant analysis test. Using the DI (≤0.3) 12 joints were classified as normal, using NA (≥105°) 24 joints and using OFA (≤3) 29. When comparing the discriminant power of NA with OFA resulting similar (P = .8324) with correct classifications of 81% using cross validation, however, the discriminant power of dysplasia of the DI resulted significantly greater (P = .0034) than OFA with correct classifications of only 59% using cross‐validation, consequently it was possible determined that of 29 patients with OFA ≤ 3, 20 had DI > 0.3. These findings demonstrated that phenotypic healthy dogs according to OFA grading can present passive hip joint laxity, as demonstrated by radiographic evaluation with distraction. Furthermore, DI can contribute to the screening of CHD when evaluated in conjunction with OFA grading.
