Abstract:
Most of the dogs with hip disorders which are not responding to medical therapy are treated by salvage surgical procedures to alleviate pain, thereby improving the limb function and quality of life. All the dogs with varying degree of hip dysplasia under the study were grouped into three groups, group I, group II and group III considering the age, degree of dysplasia and subluxation and luxation. Excision arthroplasty was done in group I dogs where femoral head and neck was excised and joint capsule was sutured to prevent bone contact between femur and acetabulum. Denervation done in group II dogs wherein craniodorsal gluteal nerves on acetabular rim were destroyed using bone curette. Trans-femoral articular wiring was done in group III dogs for subluxated and luxated hips using nylon wiring. The functional assessment of all operated dogs were assessed by WOMAC (Western Ontario and Mcmaster University Osteoarthritis Scoring Index) score and followed up to 16 weeks after obtaining owner’s feedback during 1^st, 2^nd, 4^th 7^th,10^th and 15^thweek post operatively (Annexure I). Operated dogs were followed up to 16 weeks after the surgery by considering the owners satisfaction over the telephone regarding the animal activity like getting up, climbing the stairs, chair, walking, sleeping. WOMAC score was reduced by higher score by end of 16th week in excision arthroplasty group, moderate reduction in denervation group and lower reduction in trans-articular group suggesting moderate to good improvement, moderate improvement and less moderate to moderate improvement in Group I, Group II and Group III respectively.
