Ischiectomy With Limb Preservation for a Dog With Ischial Chondrosarcoma: Case Report and Surgical Technique

ObjectiveTo describe the surgical technique for ischiectomy in the dog and to report the procedure in a case. Study DesignCase report. AnimalAn 11-year-old spayed female mixed breed dog with chondrosarcoma of the ischium. MethodsThe dog presented for hindlimb lameness and evaluation after a radiographic finding of a lytic lesion confined to the left ischium. Following staging and confirmation of stage 1 disease, an ischiectomy with preservation of the hindlimb was performed. ResultsThe dog recovered from surgery and was initially moderately lame on the hindlimb. Over time, the dog regained satisfactory hindlimb use and was alive >500 days postoperative with no evidence of local recurrence or metastatic disease. ConclusionsIschiectomy with hindlimb preservation is a technically straight-forward procedure and in this case, resulted in good hindlimb function postoperatively. The procedure should be considered for the treatment of dogs with bone tumors confined to the ischium.
