Summary
The efficiency of conservative treatment, excision arthroplasty of the femoral head
and neck and triple pelvic osteotomy for the treatment of hip dysplasia in the immature
dog were compared using locomotor, physical and radiographic examinations and owner’s
evaluation. Cases selected for this study were dogs diagnosed with bilateral hip dysplasia,
initially admitted with clinical signs (lameness, pain), immature at the beginning
of the treatment (less than 12 months of age), with both hips subjected to the same
treatment (conservative treatment, excision arthroplasty of the femoral head and neck
or triple pelvic osteotomy). These dogs never showed any musculoskeletal problems
other than hip dysplasia and the surgical treatment had been completed at least 20
months prior to re-evaluation time. Fourteen hips were re-evaluated in the conservative
group, 16 in the triple pelvic osteotomy group and ten in the excision arthroplasty
group. Locomotor, physical and owner’s evaluations demonstrated the superiority of
the triple pelvic osteotomy. These evaluations also showed that excision arthroplasty
was more efficient than conservative treatment. Radiographic examination demonstrated
the obvious superiority of the triple pelvic osteotomy over conservative treatment.
Locomotor, physical and owner’s evaluations demonstrated the superiority of the triple
pelvic osteotomy over conservative treatment and excision arthroplasty for the treatment
of hip dysplasia in the immature dog. Radiographic examination demonstrated the obvious
superiority of the triple pelvic osteotomy over conservative treatment for joint congruence
and control of degenerative joint disease.
