Elbow

A 10-month-old Yorkshire Terrier was referred for evaluation of an intermittent right thoracic limb lameness that acutely progressed to non-weight-bearing. A diagnosis of bilateral bone cysts of the humeral condyles with a pathologic fracture of the lateral aspect of the right humeral condyle was given following radiographic and histopathologic examination. Bilateral pathology necessitated consideration of treatment modalities other than amputation of the limb, as previously reported. Arthrodesis of the right elbow using a 2.0 mm locking bone plate was performed.

Objective: To report the outcome after treatment of Monteggia fractures (MF) using a novel surgical technique. Study design: Clinical reports. Methods: One dog and 1 cat were treated for MF by use of a Tightrope suture, toggle, and button implant. In both patients the fracture/luxations were reduced using an open technique and the tightrope was placed using a cannulated drill system and guide wire from cranial to caudal. Cases were retrospectively reviewed at 1, 5, and 8 weeks (cat) and at 4 weeks and 4 months (dog) for complications and outcome.

Objective: To describe incidence and type of postoperative complications in the surgical management of incomplete ossification of the humeral condyle (IOHC) and identify any risk factors associated with development of these complications. Study Design: Case series. Methods: Clinical records of dogs (n=57) that had prophylactic transcondylar screw insertion for treatment of IOHC (79 elbows) at 6 UK referral centers were reviewed. Signalment, presentation, surgical management, postoperative care, and complications were recorded.

Objective   To report the presentation and treatment of traumatic elbow luxation and to evaluate success following closed or open reduction. Design  Retrospective case series conducted between April 1999 and April 2009. Methods  Records of 14 dogs and 11 cats were reviewed for signalment, history, radiographic findings and treatment; 14 owners were contacted via phone questionnaire to assess for limb function following treatment. Fisher's two-tailed P test was used to evaluate potential risk factors for lameness.

Objective: To determine the effect of proximal ulnar osteotomy (PUO), distal ulnar osteotomy (DUO), and DUO with release of the interosseous ligament (DOLR) on displacement of the proximal ulna at the radioulnar joint. Study Design: Experimental mechanical study. Sample Population: Cadaveric, skeletally mature canine thoracic limb pairs (n=11). Methods: Thoracic limbs disarticulated at the elbow were randomly assigned to 1 of 2 groups: (A) limbs were tested with no treatment (NOTX), then with PUO; (B) limbs were tested with DUO followed by DOLR.

This report describes the diagnosis and treatment of an unusual fracture of the proximal ulna in a four-year-old male neutered Labrador Retriever dog, the orientation of which has not been reported in the veterinary literature. Computed tomography allowed fracture visualisation and aided surgical planning. Fixation was achieved using a lag screw and an anti-rotational Kirschner wire. Six month follow-up indicated satisfactory outcome with complete return to normal function.

A calcified fragment near the medial epicondyle of the humerus was originally described as an ununited medial epicondyle in 1966. Since then several papers reported similar lesions as a cause of elbow lameness. The aetiology and clinical significance of those lesions is poorly known. This paper gives an overview of the veterinary and human literature in an attempt to explain the aetiology and to suggest a diagnostic protocol and treatment plan.

A five-month-old male, German Shorthaired Pointer dog was presented for severe, bilateral, thoracic-limb-lameness, with elbow swelling, pain, and crepitus. Radiography and computed tomography confirmed bilateral incomplete ossification of the humeral condyles (IOHC), with a non-displaced incomplete fracture of the left medial epicondylar crest and condylar deformity, characterised by enlargement of the trochleas with extension of the disto-medial aspect of the bone below the normal elbow joint level, and a deformed proximo-medial aspect of the ulna and radius.

OBJECTIVE: To determine if a secondary center of ossification (SCO) of the anconeal process is present in skeletally immature dogs that do not develop an ununited anconeal process (UAP).
STUDY DESIGN: Case series.
ANIMALS: Dogs 77-154 days of age with conditions other than developmental disease of the elbow (n=78 dogs; total elbows=100).
METHODS: Mediolateral radiographic projections of the elbow were reviewed for presence or absence of a SCO of the anconeal process.
