“…It is considered a multifactorial disease, with hereditary and nutritional factors playing a significant role [19][20][21]. Since excessive intakes of calcium and energy are among the main factors for the development of the disease, it often affects mammals and birds kept on farms where fast growth is stimulated [22][23][24]. Yet another important factor conducive to the disease are distortions of hormonal balance reflected in the growth rate as well as cartilage and bone maturation.…”

The aim of our research was to examine bone health in white-tailed eagles (Haliaeetus albicilla) that died in the years 2010-2016. The research was conducted on 37 complete skeletons of eagles that came from the territories of Poland and Germany. CT and digital radiography were used in the research, and anatomical and histological analyses were carried out. We described macroscopic bone lesions in 14 birds. The most frequently found forms of pathological changes were osteophytes, which formed mainly in pelvic limbs. They were found less frequently in certain wing bones, as well as the clavicle and the sternum. In four cases, proliferative bone lesions were accompanied by osteoarthritis. Osteochondritis dissecans (OCD) was diagnosed in six birds, including one in the early stages of the disease. The lesions were found in most cases in the knee joint area and affected mainly the proximal epiphysis of the tibiotarsal bone. In one bird, a macroscopic presentation typical of osteomyelitis was observed on the tarsometatarsal bone, which might have been associated with its fracture and lysis. There was also one case of lesions typical of osteosarcoma. The analysis of individual bones of each skeleton revealed that bones from pelvic limbs more often underwent pathological changes, especially the tibiotarsus and associated joints. However, it is difficult to accept this observation as a rule without research on larger material. One cannot exclude the possibility that some types of changes in bones, such as osteosarcoma and OCD, may result from poisoning with heavy metals, particularly cadmium.

“…The long-term clinical outcome of shoulder OCD surgery is likely related to many other factors including the location, diameter and depth of the lesion and the presence and severity of concurrent osteoarthritis. 2,4,6,8,10,22 Our surgical approach can be considered a moderately challenging, minimally invasive, efficient and inexpensive alternative to other surgical approaches including arthroscopy for treatment of OCD of the humeral head. The surgical instrumentation required is commonly available and inexpensive in relation to arthroscopic equipment.…”

Objective The aim of this study was to describe a novel minimally invasive surgical approach for the treatment of shoulder osteochondritis dissecans (OCD) in dogs and to retrospectively review our clinical cases treated with this approach. Study Design The study describes a modification of Cheli surgical approach (1985), developed to reduce the degree of invasiveness as well as the incidence of postoperative complications observed in other surgical approaches to the shoulder joint. Medical records of dogs that underwent our minimally invasive approach to the scapulohumeral joint for treatment of OCD from May 2001 to May 2019 were retrospectively reviewed for intraoperative findings and complications. Clinical outcome and complications were also evaluated in the operated dogs with a minimum of a 2-month-follow-up evaluation. Results A total of 164 shoulders in 141 dogs (23 bilateral), 103 males and 38 females, were examined and treated with our modified craniolateral approach for the treatment of OCD of the humeral head. In all cases, the modified craniolateral approach allowed visibility and adequate exposure of the caudal humeral head surface. Radiographic and clinical follow-up evaluations were available in 123/164 (75%) cases. The clinical outcome was consistent with other reports using different surgical approaches for OCD lesions of the humeral head in dogs. Clinical Significance This technique provided a reliable approach for surgical treatment of canine shoulder OCD and can be considered a valid alternative to other surgical approaches including arthroscopy.

“…This observation is important, as it demonstrates the ability of radiography to detect only the more severe subclinical OC lesions in pigs reliably. Although radiography is considered currently as the standard imaging method to diagnose clinical OC [ 22 ], and most studies have investigated OC in other species [ 7 , 21 – 23 ], not many have focused on pigs [ 24 , 25 ]. Other studies have also shown significant correlations between both methods, which were joint dependent [ 13 , 26 ], however these studies were performed on older pigs and foals.…”

A longitudinal study on the performance of in vivo methods to determine the osteochondrotic status of young pigs

BackgroundIn today’s porcine industry, lameness has a major welfare and economic impact, and is often caused by osteochondrosis (OC). The etiological factors of the disease have been studied in depth, however, to this day, little is known about the natural course of the disorder and how it can be detected at an early stage in pigs. The aim of this pilot study was to assess the potential of three non-invasive techniques for the detection and monitoring of early OC processes in piglets. A group of weaned piglets (n = 19) were examined longitudinally using radiographs, a visual lameness scoring scheme and a quantitative pressure-mat based locomotion analysis system to detect OC in the humeroradial, femoropatellar and tarsocrural joints. At several time points, a selection of animals was euthanized for post-mortem examinations, including histology, which was the gold standard.ResultsIn this study, clear signs of subclinical signs of OC were observed, however, we were unsuccessful in producing clinical OC. Lesions were observed to be commonly bilaterally symmetric in the joints examined in 80 % of cases. The radiographic examinations showed a clear correlation with the gold standard, particularly when subclinical lesions were of a high histological score. Moreover, radiography was also able to detect the early repair processes, which appeared to take place at least until 14 weeks of age. Both visual scoring and pressure mat analyses showed good intra-assay reproducibility, with the pressure mat showing intra-class correlation values between 0.44 and 0.6 and the inter-observer agreement of visual scoring method was between 88 and 96 %, however their correlation to OC lesions detected by histology was very weak, with only 2 out of 12 traits for the visual scoring method showing significant and biologically logical relations to a specific joint having histological OC lesions. For the pressure mat, only a maximum of 5 associations for specific joints with histological OC lesions were found out of a possible 8.ConclusionAll tested in-vivo methods showed good reproducibility. Radiography was the most reliable technique to detect and monitor longitudinally the earliest signs of OC in these piglets. It also demonstrated that the “Point of No Return” (PNR) of the disease, when repair processes end, might be later than anticipated, after 13 weeks of age. All in all, our study shows that the timing of the use of these in-vivo methods is critical to detect and monitor OC, especially in the early phases of the disease. It also shows the difficulty in producing OC regardless of the optimization of the experimental settings in relation to the etiological factors known to induce OC.Electronic supplementary materialThe online version of this article (doi:10.1186/s12917-016-0682-z) contains supplementary material, which is available to authorized users.
