Abstracts for 2.0mm and 2.4mm Ti Locking Reconstruction Plates Repair of long-bone fractures in cats and small dogs with the Unilock mandible locking plate system Voss K, Kull MA, Haessig M, Montavon PM VCOT, 2009 Objectives: To retrospectively evaluate stabilisation of long-bone fractures in cats and small dogs using the Unilock system. Methods: Medical histories and radiographs of consecutive patients with long-bone fractures stabilised with the Unilock system were reviewed. Cases with follow-up radiographs taken at least four weeks postoperatively were included. Signalment of the patient, fracture localisation and type, primary fracture repair or revision surgery, single or double plating, and complications for each patient were noted. Additionally, implant size, number of screws, number of cortices engaged with screws, and number of empty holes across the fracture were evaluated in fractures where a single plate had been applied. Results: Eighteen humeral, 18 radial, 20 femoral, and 10 tibial fractures were treated. The Unilock system was used for primary repair in 44 fractures and for revision surgery in 22 fractures. Two plates were applied in 17 fractures, and a single plate was applied in 49 fractures. Follow-up radiographs were taken four to 109 weeks postoperatively. Complications were seen in 12 animals and 13 fractures (19.7%). Fixation failure occurred in seven fractures (10.6%). Cases with a single plate that suffered fixation failure had thinner screws in relation to bone diameter than cases with double plates, and more screws in a main fragment than those without fixation failure. Clinical significance: The Unilock system is a suitable implant for fracture fixation of long bones in cats and small dogs.
Mandibular reconstruction after gunshot trauma in a dog by use of recombinant human bone morphogenetic protein-2 Lewis JR, Boudrieau RJ, Reiter AM, Seeherman HJ, Gilley RS JAVMA, 2008 Case Description—A 6-year-old German Shorthaired Pointer was evaluated for possible reconstruction of a mandibular defect resulting from gunshot trauma. Clinical Findings—A 5-cm defect of the right mandibular body was evident. A segment of the mandibular body was removed 9 weeks earlier because of severe contamination and comminution associated with gunshot trauma. Subsequent right-sided mandibular drift resulted in malocclusion in which the left mandibular canine tooth caused trauma to mucosa of the hard palate medial to the left maxillary canine tooth. The right maxillary canine tooth caused trauma to gingiva lingual to the right mandibular canine tooth. Treatment and Outcome—The right mandible was stabilized with a 2.0-mm maxillofacial miniplate positioned along the lateral alveolar margin and a 2.4-mm locking mandibular reconstruction plate placed along the ventrolateral mandible. An absorbable compressionresistant matrix containing collagen, hydroxyapatite, and tricalcium phosphate was soaked in recombinant human bone morphogenetic protein-2 (rhBMP-2; 7.2 mL of a 0.5 mg/mL solution for a dose of 3.6 mg) and placed in the defect. By 4 weeks after surgery, an exuberant callus was evident at the site of the defect. By 7 months after surgery, the callus had remodeled, resulting in normal appearance, normal occlusion, and excellent function of the jaw. Clinical Relevance—Mandibular defects resulting from gunshot trauma can be treated by removal of contaminated tissue and comminuted bone fragments, followed by staged reconstruction. The combination of rhBMP-2 and compression-resistant matrix was effective in a staged mandibular reconstruction in a dog with a severe traumatic mandibular defect.
Immediate mandibular reconstruction of a 5 cm defect using rhBMP-2 after partial mandibulectomy in a dog. Spector DI, Keating JH, Boudrieau RJ. Vet Surgery, 2007 Objective— To report treatment of a complex odontoma of the mandible by partial mandibulectomy and immediate surgical reconstruction using bridging plate fixation with a synthetic graft. Study Design— Clinical case report. Animals— A 4-year-old male castrated cocker spaniel. Methods— Immediate reconstruction of the left mandible (5 cm gap) was performed after complete excision of a complex odontoma. Locking plate fixation was applied immediately before complete excision of the mass. Fixation was removed, then after partial mandibulectomy, including all abnormal tissue, restored to achieve occlusion. The resulting mandibular defect was filled with recombinant human bone morphogenetic protein-2 (rhBMP-2) delivered in an absorbable collagen sponge containing hydroxyapatite/tricalcium phosphate granules (compression resistant matrix [CRM]). Results— New bone growth was evident radiographically and on palpation at 3 months. Bony remodeling was evident during follow-up examinations up to 26 months. Bone collected by biopsy at the graft site at 7 months had robust new bone formation and evidence of continued remodeling. Only minor complications (repeated intraoral plate exposure) were encountered postoperatively and were easily resolved. Conclusions— An osteoinductive factor (rhBMP-2/CRM) was successfully used as a graft substitute in immediate reconstruction of a large mandibular defect. Clinical Relevance— Immediate reconstruction of large mandibular defects with osteoinductive materials as a graft substitute may be a viable alternative to partial mandibular resection or radiation therapy for benign odontogenic tumors in dogs.
Use of the ComPact UniLock System for ventral stabilization procedures of the cervical spine: a retrospective study. Voss K, Steffen F, Montavon PM. VCOT, 2006 This study evaluates clinical application of the ComPact UniLock system for ventral stabilization of the cervical spine. Patient material included 13 consecutive cases, 12 dogs and one cat, with cervical spinal instabilities secondary to disc-associated wobbler syndrome (six dogs), traumatic, iatrogenic, and disc-associated cervical spinal instability of small dogs (four cases), cervical spinal fractures (one dog and one cat), and congenital atlantoaxial instability (one dog). The 2.0 system was used in smaller patients and the 2.4 system was applied in large dogs. Implant failure was observed on follow-up radiographs in one dog with a healed C2 fracture and screw pullout occurred in one dog with caudal cervical spondylomyelopathy, necessitating revision surgery. Implants remained stable throughout the follow-up period in the other cases. 'Good' or 'excellent' clinical outcome was achieved in 12 patients, including the dog with revision surgery. One dog had to be euthanatized due to postoperative deterioration of neurological status and development of pneumonia. The ComPact UniLock system was found to be a suitable implant for treating cervical instabilities of different origin in both small and large patients with lesions from C1/C2 to C6/C7. Some problems were encountered in the dogs with disc-associated Wobbler syndrome, such as lack or slow rate of vertebral fusion and partial collapse of the distracted intervertebral space on follow-up radiographs. A lack of adequate fusion was most likely related to grafting techniques used.
The ComPact UniLock 2.0/2.4 system and its clinical application in small animal orthopedics. Keller MA, Voss K, Montavon PM. VCOT, 2005 This study describes the titanium ComPact UniLock 2.0/2.4 locking plate system (Stratec Medical, Oberdorf, Switzerland) and reports its application in nine selected clinical cases. The system was found useful for a variety of indications. Three categories of clinical applications are illustrated. They include (a) long bone fractures, (b) cervical spinal fractures and instabilities and (c) joint instabilities and luxations. A brief introduction to the system has already been published.
Mandibular Reconstruction of a Partial Hemimandibulectomy in a Dog with Severe Malocclusion Boudrieau RJ, Mitchell SL, Seeherman H Vet Surgery, 2004 Objective— To report treatment of severe mandibular malocclusion (after left partial hemimandibulectomy, ∼7 cm gap). Study Design— Clinical report. Animals— A 14-month-old golden retriever. Methods— After corrective osteotomy of the right horizontal mandibular ramus, normal occlusion was reestablished and temporarily maintained while both mandibles were stabilized by miniplates on the lateral alveolar surface spanning the bilateral mandibular defects (right=1.5 cm, left=7 cm). A fenestrated, monocortical rib graft was positioned beneath the left gingival surface to protect the synthetic graft, which was secured to the miniplate. A mandibular reconstruction plate (right) and a locking mandibular reconstruction plate (left) were secured to the ventral borders of the mandibles. Recombinant bone morphogenetic protein-2 delivered in collagen tricalcium phosphate sponges (rhBMP-2 collagen-TCP sponge) was inserted into both mandibular defects. Results— New bone formation was identified at 3 months and bony remodeling was evident at recheck examinations up to 4 years. Scintigraphy (6 months, 1 year) confirmed graft revascularization and viability. Bone collected (1 year) from the left defect site had robust new bone formation and evidence of continued remodeling. Only minor complications were encountered during the postoperative period and were easily resolved. Conclusions— Reconstruction of a large mandibular defect was facilitated by use of an osteoinductive factor (rhBMP-2 collagen-TCP sponge) as a graft substitute. Clinical Relevance— One-step salvage and reconstruction facilitated by use of an osteoinductive factor, as a graft substitute, may be an alternative strategy for repair of large mandibular defects. |
