Intraoperative facet joint injury during anterior cervical discectomy and fusion: an experimental study.

Object: Disorders of the cervical spine can be successfully addressed by surgical intervention when the choice of such intervention takes into account the possible complications in the treated and adjacent structures. The aim of this study was to investigate the potential for intraoperative trauma in cervical zygapophysial joints and to describe possible pathological changes that may occur during cervical spine surgery.

Methods: Fifteen sheep underwent surgical intervention via an anterior cervical approach; discectomy at the C5-6 level was performed.

Ocular manifestations of natural canine monocytic ehrlichiosis (Ehrlichia canis): a retrospective study of 90 cases.

Objective: To investigate the spectrum, prevalence and treatment response rate of ocular manifestations associated with natural canine monocytic ehrlichiosis (CME) due to Ehrlichia canis.

Methods: The medical records of 90 dogs that were admitted for primary ocular problems and reacted positive for E. canis serum antibodies were reviewed.

A retrospective study of presentation, treatment, and outcome of free-ranging raptors in Greece (1997-2000).

A retrospective study was conducted on free-ranging raptors (n = 402) presented to the Veterinary Medical Teaching Hospital, School of Veterinary Medicine, Aristotle University of Thessaloniki, Greece, during a 3-yr period (1997-2000). Representatives of 19 species were admitted from taxonomic orders Accipitriformes (n = 295), Falconiformes (n = 35), and Strigiformes (n = 72). Traumatic injuries (n = 305, 75.

The lymph drainage of the neoplastic mammary glands in the bitch: a lymphographic study.

The purpose of this investigation was to study the lymph drainage of the neoplastic mammary glands in the bitch using indirect lymphography. The main conclusions drawn from the study of 41 natural cases were as follows: the first or cranial thoracic and second or caudal thoracic neoplastic mammary glands usually drain into the ipsilateral axillary lymph nodes and rarely into the ipsilateral axillary and sternal lymph nodes, simultaneously. The third or cranial abdominal neoplastic mammary gland usually drains into the ipsilateral axillary and superficial inguinal lymph nodes simultaneously, but sometimes only cranially into the ipsilateral axillary lymph nodes.

Osseous lesion of the calcaneus following the use of shock wave therapy in a horse.

An 8-year-old Dutch warmblood gelding was presented with a mechanical lameness (2/10) because of the presence of a soft tissue injury on the top of the right tuber calcanei. Plain radiographs of the tarsus demonstrated the presence of soft tissue swelling caudal to the right tuber calcanei, without osseous involvement, and ultrasonography revealed excessive scar tissue within and around the superficial digital flexor tendon. Extra-corporeal shock wave therapy was applied on the right hock to decrease the amount of scar tissue.
