摘要:

A porous‐coated modular total hip system was developed for uncemented implantation in dogs. The operative technique was developed in cadaver bones and live animals. One hundred uncemented total hip arthroplasties were performed in 92 dogs. Results were successful in 98% of the joints during follow‐ups of 3 months or more. Complications included three luxations of the prosthetic joint, two fissure fractures of the femoral cortex, and one complete displacement of the acetabular component from its bony bed. Four complications were resolved successfu

摘要:

Half‐pin (type 1) external skeletal fixators with four, three, and two fixation pins and an intramedullary pin, and four‐pin external skeletal fixators without an intramedullary pin were applied to prepared canine femurs. Load to failure, load to yield, safe load, and stiffness under compressive and torsional loads were calculated. When tested in compression, all measurements for the four‐pin fixators with an intramedullary pin were significantly higher than for the two‐pin fixators with an intramedullary pin. The values for all parameters except load to yield were significantly higher for the four‐pin fixators with an intramedullary pin than for the four‐pin fixators without an intramedullary pin. When tested in torsion, all measurements for the four‐pin fixators with an intramedullary pin were significantly higher than for the two or three‐pin fixators with an int

摘要:

The functional results of partial or total hemipelvectomy in seven dogs and two cats with sarcomas involving the pelvis were excellent, and the cosmetic outcome was acceptable to all owners. Tumors in two dogs were inoperable. Locally recurrent cancer occurred in two animals and metastases occurred in three animals. Three dogs survived longer than 2.5 years and the overall and disease‐free survival at 12 months was 62%. It appears that osteosarcoma of the pelvis is at least as aggressive as osteosarcoma of limbs and, unless effective adjuvant therapy is used, poorer survival results are likely in dogs with osteosarcoma than with other sarcomas of the pelvis. Hemipelvectomy is an aggressive surgical procedure that can be used successfully in selected dogs and cats with cancer involving the pelvi

摘要:

Collagenase, a proteolytic enzyme, was injected intradiscally in nine clinically normal, middle‐aged beagles. Calcium chloride diluent solution (control), 100 ABC units of collagenase, and 250 ABC units of collagenase, were injected in randomly selected intervertebral discs (T13‐L1 to L5‐L6). On day 11, the discs injected with collagenase were narrowed radiographically, but there was no significant change in myelograms. Grossly and histologically, there was dissolution of the intervertebral discs, mainly nucleus pulposus, and protrusion of nucleus material in the vertebral body through bony end‐plates in discs injected with collagenase. Collagenase chemonucleolysis may be an alternative to spinal surgery for intervertebral disc protrusion

摘要:

The percentages of change in cross‐sectional area and dorsoventral height of the rima glottidis were measured after seven types of laryngoplasty in 30 postmortem canine specimens. The mean increases in area after each procedure were, in decreasing order, bilateral cricoarytenoid disarticulation with interarytenoid sesamoid band transection before placement of arytenoid abduction sutures 350%± 42%, bilateral placement of arytenoid abduction sutures 318%± 40%, bilateral cricothyroid disarticulation before placement of arytenoid abduction sutures 255%± 51%, modified castellated laryngofissure 244%± 30%, unilateral cricoarytenoid disarticulation with interarytenoid sesamoid band transection before placement of an arytenoid abduction suture 161%± 25%, unilateral placement of an arytenoid abduction suture 151%± 24% and unilateral cricothyroid disarticulation before placement of an arytenoid abduction suture 108%± 25%. Bilateral cricoarytenoid disarticulation with interarytenoid sesamoid band transection before placement of arytenoid abduction sutures resulted in a significantly greater increase in rima glottidis area than modified castellated laryngofissure and all unilateral arytenoid abduction techniques. Modified castellated laryngofissure resulted in a significantly greater increase than unilateral placement of an arytenoid abduction suture and cricothyroid disarticulation before placement of an arytenoid abduction suture. Bilateral disarticulation of the cricothyroid joint before placement of arytenoid abduction sutures resulted in significant collapse of the dorsoventral height of the rima g

摘要:

Single or multiple rib resection was performed in 40 dogs for the treatment of primary osteosarcoma or chondrosarcoma. The resulting thoracic wall defect was closed with polypropylene (12 dogs), primary muscle flap (16 dogs), diaphragmatic advancement (10 dogs), or a combination (2 dogs). Few immediate (<2 weeks) postoperative complications were observed. Twenty dogs with osteosarcoma had a median survival time of 3.3 months (range, 0.5 to 23 months), with a 20% 6‐month survival time. Metastases occurred in all the dogs. Fourteen dogs with chondrosarcoma followed up longer than 2 weeks had a median survival time of 10.7 months (range, 0.5 to 36 months) with a 64% 6‐month survival time. Eight dogs developed metastases, five died from concurrent disease, and one dog is alive. Dogs with chondrosarcoma survived significantly longer than dogs with osteosarcoma. Survival time was not related to tumor size or number of ribs resec

摘要:

Four years after successful implantation of a pleuroperitoneal shunt in a dog with persistent pleural effusion, signs of lethargy and dyspnea reappeared. Although the shunt was still functional, compartmentalization of the right pleural space eventually isolated a pocket of fluid, causing dyspnea. Symptomatic relief was achieved for at least 11 months by contralateral implantation of a second shunt.

摘要:

Urinary diversion by transplantation of both ureters into a reservoir constructed from 60 cm of jejunum was performed in six clinically normal dogs. The reservoir was connected to a stoma on the abdominal wall through a valve constructed from a short segment of intussuscepted bowel to provide continence. The reservoir was emptied three times daily by catheterization. One dog did not survive the surgical procedure and two dogs died within 1 week of surgical complications. The postoperative capacity of the reservoir in surviving dogs was 100 to 200 mL; it increased during the first month to 600 to 750 mL. Continence was excellent in two dogs. One dog was continent until month 2, when partial slippage of the intussusception occurred. A reversible hyponatremic, hypochloremic, hypokalemic metabolic acidosis developed. Bacteriuria was not responsive to systemic or local instillation of antibiotics. Ascending pyelonephritis, hydroureter, and hydronephrosis occurred in two dogs. Struvite urinary calculi formed in one dog. The procedure as described would be unsuitable for clinical use in dogs.

摘要:

Short bowel syndrome occurred in four dogs after extensive (74% to 88%) small intestinal resection. Weight loss and diarrhea were the principal clinical signs. Treatment was based on the severity of clinical signs. One dog is alive after 27 months. Three dogs died within 3 months. The prognosis depends on the extent and site of resection, degree of intestinal adaptation, preoperative condition, and postoperative care.
