The key to prevention of the variousgrowth-associated bone disorders lies in the attempt to control for both genetic andenvironmental risk factors that may increase susceptibility. As discussed earlier in thisarticle, proper nutrition of growing puppies in the form of restricted feeding throughavoidance of high-calorie diets and oversupplementation are steps in prevention from anenvironmental perspective. Another potential method for reducing incidence in dogs knownto be at higher risk for developing growth-associated skeletal disorders may be throughadministration of preventative drugs. Much clinical research has focused recently on theuse of disease-modifying osteoarthritis drugs (DMOADs), also called chondroprotectivedrugs, that claim to prevent, reduce or reverse the degeneration of cartilage resultingfrom joint abnormalities. From a genetic standpoint, in cases of bone disorders suspiciousor known to have genetic transmittance, selective breeding to eliminate affected dogs fromthe gene pool is one step in reducing occurrence in future generations. Several methodsfor genetic screening have been developed specifically for this purpose.
Diagnosis: Survey radiography is usually accurate for thediagnosing HD in dogs presenting with clinical symptoms. However, HD may occurconcurrently with a number of other skeletal, muscular and neurological disorders. Often adog presenting with recent symptoms of hind limb lameness and indications of advanced hiposteoarthritis on radiographs will be found to have lameness associated with knee ligament(cruciate ligament) disorders rather than HD upon closer scrutiny. Therefore, radiographicevidence of HD alone is not sufficient to conclude that symptoms are directly associatedwith HD, and a complete physical exam and history of the dog is required to rule out otherdisease processes. In terms of genetic selection against HD, x-ray only demonstratesactual appearance (phenotype) of hips at one given point in time, therefore, there arelimitations to this method's predictive value in terms genetic assessment for HD (see ).For example, many dogs that pass radiographic OFA standards for absence of HD at two yearsof age may go on to develop HD later in life and therefore, should still be consideredgenetically predisposed to HD. Measurement of muscle laxity as early as 4 months of ageusing the PennHip DI score has been clinically shown to provide an accurate predictiveassessment for dogs with low risk ( risk (DI > 0.7) fordeveloping HD sometime within their lifetimes. Scores between 0.4 and 0.7 at this age,however, are less reliable for predicting risk and require reassessment of DI at 6 to 12months of age.

There are multitudes of disorders that may presentsymptoms of joint pain and lameness in growing, active dogs. Observation of clinicalsymptoms and physical examination alone, therefore, are not sufficient to accuratelydiagnose growth-associated disorders. Survey radiography (x-ray imaging) is often reliablefor the identification and differentiation of many bone and joint disorders. Often,however, particularly in the early stages of disease, radiographic evidence of bonechanges associated with a disease process may be minimal or absent despite clinicalsymptoms. Additionally, some joint abnormalities are not clearly discerned by conventionalx-rays. Therefore, in the presence of significant pain and lameness despite negativefindings on x-ray, computed axial tomography (CT) or magnetic resonance imaging (MRI) isoften successful in detecting bone and joint abnormalities that are overlooked by surveyradiography. Additionally, CT and MRI are considered invaluable for pre-operative planningin cases where corrective surgery is indicated. Another approach that may be used alone or incombination with diagnostic imaging is the laboratory collection and analysis of jointfluid from the effected limb. This method may be helpful in confirming presence of jointdisease even in the absence of detectable disease by imaging techniques. Additionally,joint fluid analysis will discern between inflammatory and non-inflammatory joint disease,as well as detect presence of a bacterial infection. However, a major limitation of jointfluid analysis is that it is unable to differentiate between one inflammatory ornon-inflammatory disorder and another.

Many breeders, concerned with the physical"soundness" of purebred dogs, have attempted to reduce incidence of skeletaldiseases within their breeds' populations. With the knowledge that many developmental boneand joint disorders are genetically transmitted, methods for screening afflicted dogs andeliminating them from the breeding pool have been devised in the hopes of reducingincidence of bone disorders and increasing genetic soundness of future progeny. However,there is strong evidence suggesting that joint disorders such as elbow and hip dysplasiasare polygenic: conditions caused by more than one gene. As with all polygenic traits,environmental factors significantly influence the degree of expression and rate ofprogression of these disorders. These factors are likely responsible for the difficultyencountered when screening breeding stock and applying results to evaluate genetic risk.
Hyaluronan is a slow-acting drug that provideslong-term benefits related to pain relief and restoration of function. Pre-clinicaltesting to determine potential benefits for human patients was conducted in canine modelsfor osteoarthritis. As such, results from these studies suggest that hyaluronan may haveclinical benefits for use in dogs. Though clinical trials using hyaluronan to treatosteoarthritis in horses have been conducted, no such trials have been conducted in dogsat the time this article was written.

The most common bone disorders affecting growingdogs will be described here. The disorders have been divided into two groups: 1) those inwhich one or more stages in the construction of bone is interrupted and 2) those affectingthe actual formation of bones and joints.:This disorder occurs when calcification does not follow cartilage growth. The cartilagecontinues to grow, becomes thicker than normal, and vessels from the bone marrow areunable to penetrate. Under these conditions, bone formation does not proceed and cracksand crevices form in the abnormally thickened cartilage. Fragments of cartilage eventuallydetach from the underlying cartilage and become lodged within the affected joint. Affectedjoints, listed from most to least commonly involved, are the shoulders, knees, elbows,hocks, and rarely the joints of the spinal column. Males have a higher risk than femalesfor developing OCD.
Elbow Replacement Surgery, Recovery, What to Expect
Prognosis: Mild to moderate OCD lesions may heal spontaneously with4 to 6 weeks of crate rest and leash walking. More severe OCD lesions or those occurringin dogs whose owners are unable to enforce exercise restriction usually requireconservative or surgical therapeutic intervention to reduce secondary and long-termcomplications associated with osteoarthritis. Untreated, advanced lesions or those that donot respond to conservative therapy usually require surgical intervention to inhibitprogression of debilitating disease.

:When calcified cartilage fails to be penetrated by vesselsfrom the bone marrow, the unvesiculated tissue dies. Excess mineralization takes placeresulting in calcium deposits at the affected sites. The radius and ulna bones of theforelimbs and the tibia bone of the hind limbs are all affected in dogs with HOD. Malesand females are equally at risk for developing HOD.

Treatment: Surgery is widely considered the best option for elbowdysplasias associated with UAP and OCD. Dogs treated early in the course of the diseasewhen there is only minimal osteoarthritis exhibit the best long-term outcome in terms ofreduction of symptoms and restoration of activity. However, despite surgical intervention,most of these dogs will develop progressive osteoarthritis and likely require long-termtherapy with non-steroidal anti-inflammatories and/or chondroprotective drugs. Clinicaldata on the surgical treatment of FMCP has thus far demonstrated no significant gains overnon-surgical treatment for this condition. Treatment alternatives to surgery include rest,weight reduction, low-impact exercise, and drug therapy with non-steroidalanti-inflammatories and/or chondroprotective drugs. No comparison studies between surgicaland non-surgical treatment for IC has yet been conducted. When surgical intervention isselected, arthroscopic surgery to correct bone malalignment has proven a successfulsurgical option.
