Management

Tibial tuberosity transposition-advancement for treatment of medial patellar luxation and concomitant cranial cruciate ligament disease in the dog. Surgical technique, radiographic and clinical outcomes.

Summary:

To report surgical technique, morphometric effects and clinical outcomes for tibial tuberosity transposition-advancement(TTTA), sulcoplasty and para-patellar fascial imbrication for management of concomitant medial patellar luxation (MPL) and cranialcruciate ligament (CCL) disease in 32 dogs.

Conclusion:

Thirty-nine stifles were treated by surgery. Medial patellar luxation grade ranged from II to IV/IV. The CCL rupture was complete in 17/39 stifles, and incomplete in 22/39. Complications occurred in 11/39 stifles including MPL recurrence (n=4). Resolution of subjectively-assessed lameness occurred in 29/39 stifles at the six to eight week assessment. Resolution of lameness was eventually documented in 35/39 stifles (4/39 lost to follow-up), and was maintained at the six to 20 month reassessment where available. The TTTA induced relative patella baja in 31/39 stifles. Magnitude of actual tibial tuberosity advancement was lower than that predicted by cage size.

Long-term results of conservative treatment, excision arthroplasty and triple pelvic osteotomy for the treatment of hip dysplasia in the immature dog

Summary:

The efficiency of conservative treatment, excision arthroplasty of the femoral head and neck and triple pelvic osteotomy for the treatment of hip dysplasia in the immature dog were compared using locomotor, physical and radiographic examinations and owner’s evaluation.

Conclusion:

Radiographic examination demonstrated the obvious superiority of the triple pelvic osteotomy over conservative treatment for joint congruence and control of degenerative joint disease.

Tibial plateau leveling osteotomy or tibial tuberosity advancement?

Summary:

To review the proposed biomechanical basis of the tibial plateau leveling osteotomy (TPLO) and tibial tuberosityadvancement (TTA) and recommendations for these techniques.

Conclusion:

There are many similarities between TPLO and TTA although it remains to be fully elucidated if either procedure is superior and under what conditions.

Effect of surgical technique on radiographic fusion of the anconeus in the treatment of ununited anconeal process

Summary:

The aim of this study was to determine if internal fixation of the anconeus combined with a proximal ulnar osteotomy was more likely to result in fusion of the anconeus to the ulna compared with a proximal ulnar osteotomy alone.

Conclusion:

A total of 47 elbows (44 dogs) were identified. Of these, 28 cases (average age 7.6 months) were treated with proximal ulnar osteotomy (of which eight were stabilised with an intramedullary pin) alone. Nineteen cases (average age 7.1 months) were treated with proximal ulnar osteotomy + internal fixation. The two groups were not significantly different in age (P=0.638, Mann-Whitney U test). Fourteen of 28 cases with proximal ulnar osteotomy alone displayed anconeal union at follow-up compared with 16 of 19 cases of proximal ulnar osteotomy + internal fixation, and this difference was statistically significant (P=0.029, Fisher’s exact test).

Healing and repair of ligament injuries in the knee

Summary:

Although methods of treating ligamentous injuries have continually improved, many questions remain about enhancing the rate, quality, and completeness of ligament healing. It is known that the ability of a torn ligament to heal depends on a variety of factors, including anatomic location, presence of associated injuries, and selected treatment modality. A grade III injury of the medial collateral ligament(MCL) of the knee usually heals spontaneously. Surgical repair followed by immobilization of an isolated MCL tear does not enhance thehealing process. In contrast, tears of the anterior cruciate ligament (ACL) and the posterior cruciate ligament often require surgical reconstruction. The MCL component of a combined ACL-MCL injury has a worse prognosis than an isolated MCL injury.

Conclusion:

The results of animal studies suggest that nonoperative treatment of an MCL injury is effective if combined with operative reconstruction of the ACL. Experimentation using animal models has helped to define the effects of ligament location, associated injuries, intrinsic factors, surgical repair, reconstruction, and exercise on ligament healing. New techniques utilizing growth factors and cell and gene therapies may offer the potential to enhance the rate and quality of healing of ligaments of the knee, as well as other ligaments in the body.

COAST Development Group’s international consensus guidelines for the treatment of canine osteoarthritis

Summary:

This report describes consensus guidelines and recommendations for the treatment of canine osteoarthritis (OA) according to the “Canine OsteoArthritis Staging Tool excluding radiography” (COASTeR) stage of OA, by the COAST Development Group. The recommendations are based on evidence-based medicine and clinical experience and are proposed with international relevance in mind. The aim is to provide veterinarians with a practical reference to consolidated information and to support the development of patient-specific OA management protocols and informed treatment choices based on the stage of OA.

Conclusion:

Canine osteoarthritis is a complex disease and only animal healthcare professionals with personal knowledge of the patient can optimize care plans to meet the needs of the patient and requirements of the pet caregiver. This proposal for the first international guidelines for the treatment of canine osteoarthritis (OA), according to the COASTeR OA stage, is intended to provide a practical reference to evidence-based recommendations and expert opinion while leaving decision-making and the development of protocols appropriate to each dog’s specific situation, firmly in the hands of the consulting veterinarian. The authors encourage the use of the COAST staging tool and the COAST canine OA treatment guidelines proposal, and welcome feedback to help guide future updates and the optimization of both ([email protected]).

Tibial tuberosity advancement in 65 canine stifles.

Summary:

The tibial tuberosity advancement (TTA) procedure was developed to treat dogs with cranial cruciate ligament deficient stifles. A retrospective, descriptive study was performed on 57 dogs that underwent unilateral or bilateral TTA.

Conclusion:

TTA subjectively appears to be a useful alternative in the management of cranial cruciate ligament disease. Few severe complications were encountered. Good clinical outcome and owner satisfaction was reported with the procedure in this set of cases.

Canine hip dysplasia treated by juvenile pubic symphysiodesis. Part I: two year results of computed tomography and distraction index.

Summary:

To measure one and two year effects of juvenile pubic symphysiodesis (JPS) in puppies defined as ‘at-risk’ for canine hip dysplasia (CHD) using the following objective hip conformation criteria: Acetabular angle (AA), dorsal acetabular rim angle (DARA) and hip laxity (PennHIP© distraction index (DI).

Conclusion:

Juvenile pubic symphysiodesis surgery at 12-24 weeks of age significantly improved hip conformation and decreased laxity in at-risk CHD dogs. Early-age (12 to 16 week) recognition of hip laxity offered greater JPS benefits than surgery performed at 19- to 24-weeks-old. Dogs with severe laxity (DI≥0.70) continued to increase in osteoarthritis. An early (12-16 weeks) positive laxity test (Ortolani) should alert one to obtain objective laxity determinations (PennHIP© DI).

Long-term radiographic comparison of tibial plateau leveling osteotomy versus extracapsular stabilization for cranial cruciate ligament rupture in the dog.

Summary:

Comparison of 2 methods of surgical management of cranial cruciate ligament (CCL) injury in large-breed dogs using a radiographic osteoarthrosis (OA) scoring system.

Conclusion:

Based on logistic regression analysis, dogs with larger OA score differences were 5.78 times more likely to have had ECR than TPLO.

Arthroscopic documentation of elbow cartilage pathology in dogs with clinical lameness without changes on standard radiographic projections.

Summary:

To document cartilage damage associated with elbow lameness in dogs without radiographic signs.

Conclusion:

Elbow pathology not associated with radiographic changes can be identified by CT and scintigraphy. Coronoid pathology is the most likely diagnosis.
