Objectives— To (1) determine bone contact with the outer surface and ingrowth into the perforated outer shell of the Kyon acetabular component at 2, 6, and 12 months after total hip replacement (THR) and (2) determine correlation between radiographic lucency surrounding the cup–bone interface and bone contact and ingrowth.
Study Design— Experimental study.
Animals— Large breed dogs (n=11) with and without hip dysplasia.
Methods— Force platform gait analysis was performed preoperatively and 2, 6, and 12 months after THR. Curvilinear length of lucency (CLL) was measured on pelvic radiographs. Tissue contact with the outer cup and ingrowth into the cup were determined histomorphometrically at 2, 6, and 12 months.
Results— Peak vertical force and vertical impulse of the treated and control hind limb were not significantly different at any time. Median bone contact with the outer cup surface was 77%, 48%, and 76% at 2, 6, and 12 months, respectively. Median bone ingrowth into the cup perforations was 50%, 20%, and 44% at 2, 6, and 12 months, respectively. Median bone ingrowth to the inner cup surface was minimal at any time. CLL did not correlate with bone ingrowth.
Conclusions— Bone ingrowth into cup perforations occurred in each dog and was already present 2 months after THR, but most of the inner cup space remained vacant.
Clinical Relevance— Radiographic lucency surrounding the cup–bone interface does not allow assessment of bone contact with the outer surface or bone ingrowth into the Kyon cup in dogs without clinical problems. 相似文献

Objective— To report a surgical technique for primary repair of separation of the annular and auricular cartilages of the ear and long-term outcome.
Study Design— Case series.
Animals— Cats (3) and dogs (2) with ear canal separation.
Methods— Medical records (1998–2007) of dogs and cats with ear canal separation were reviewed. Long-term outcome was obtained by telephone interview of owners or referring veterinarians.
Results— Three cats and 1 dog had ear canal separation after being hit by a car; there was no history of trauma in 1 dog. Successful repair was achieved by a caudal approach to the ear canal, identifying and debriding separated cartilage edges and using primary repair. A patent ear canal was confirmed in all animals by otoscopy 4–12 weeks later and by ear canalography in 3 animals. Long-term outcome was excellent with no reported complications 10–90 months later (median 24 months).
Conclusions— Both acute and chronic separation between the annular and auricular cartilages, in the absence of middle ear disease, can be successfully treated using primary repair via a caudal approach to the ear canal, with excellent long-term outcome.
Clinical Relevance— Primary repair should be considered in animals with separation of the annular and auricular cartilages. 相似文献

Objective: To report the clinical findings and treatment of a heifer with suppurative splenitis.
Study design: Clinical report.
Animals: A 30-month-old heifer.
Methods: Splenectomy in the standing calf after local anesthesia and 13th rib resection.
Results: The heifer had an uneventful recovery but was culled because of septic tarsitis 3 months later.
Conclusions: Splenectomy is a useful treatment for cattle with traumatic splenitis if diagnosed early. Partial splenectomy may have prevented the late complication of septic tarsitis.
Clinical Relevance: Suppurative splenitis is usually a complication of hardware disease and has a grave prognosis unless splenectomy is carried out. 相似文献

Objective— To report the technique, complications, and effectiveness of thoracoscopic subphrenic pericardectomy (SPP) using double‐lumen endobronchial intubation for alternating 1‐lung (OLV) in healthy dogs. Study Design— Prospective cohort study. Animals— Mature purpose‐bred dogs (n=7). Methods— Bronchoscope‐assisted placement of a left‐sided double‐lumen endobronchial tube, immediately before surgery, allowed intraoperative alternation of ventilation between lung fields. A camera portal was established in a subxyphoid location. Two instrument portals were established at the 4th–6th intercostal spaces on the right and left sides. A vessel‐sealing device was used to create the subphrenic pericardectomy. After termination of the procedure, dogs were humanely euthanatized under anesthesia and necropsy performed. In each dog, the extent of pericardectomy and any complications were evaluated. Results— Technical difficulties with tube placement occurred in 4 dogs, but alternating OLV was achieved in all dogs and SPP completed successfully. Median surgical time was 87.5 minutes (range, 80–105 minutes). At necropsy, 0.5–2 cm of pericardial tissue remained ventral to the intact phrenic nerve in 6 dogs; in 1 dog, the phrenic nerve was transected on the left side only. Conclusions— Thoracoscopic subphrenic pericardectomy is a technically feasible procedure in healthy dogs. Double‐lumen endobronchial intubation allowed alternating OLV without intraoperative bronchoscopically guided tube manipulation in all but 1 dog. Clinical Relevance— Thoracoscopic subphrenic pericardectomy could potentially be used for management of conditions where relief of pericardial constriction or access to intrapericardial structures is desired. 相似文献

Objective— To describe a laparoscopic‐sutured gastropexy technique in dogs and evaluate the tensile strength of the adhesion and effects on gastric function. Study Design— Experimental study. Animals— Female beagle dogs (n=7). Methods— A laparoscopic‐sutured gastropexy technique was evaluated by ex vivo tensile distraction tests 10 weeks after surgery. The effect of the adhesion on gastric emptying, mucosal permeability, and systemic inflammation were evaluated by monitoring the C‐reactive protein (CRP) and sucrose permeability, and by radiographic evaluation of gastric emptying 2 weeks before and 10 weeks after surgery. Results— Mean (±SD) tensile force to disrupt adhesions was 51.1±16.4 N. There was no significant postoperative increase in CRP concentration or change in sucrose permeability. The area under the curve representing the postprandial decrease in gastric radiographic area increased by 11% after gastropexy. Conclusions— This laparoscopic gastropexy technique had appropriate mechanical and functional characteristics with limited morbidity. Clinical Relevance— This laparoscopic‐sutured gastropexy provides adhesion strength comparable with other gastropexy techniques tested at 10 weeks postoperatively. Only minor changes in gastric emptying were observed 10 weeks after surgery. 相似文献
