Clinical evaluation of a mini locking plate system for fracture repair of the radius and ulna in miniature breed dogs

SummaryObjectives: To retrospectively evaluate the effectiveness of a novel 1.2 mm mini locking plate system in treating fractures of the radius and ulna in miniature breed dogs.Methods: Medical records and radiographs of miniature breed dogs with fractures treated with a 1.2 mm mini locking plate system were reviewed. The inclusion criteria were: body weight of 2.5 kg or less, trans-verse or short oblique fracture of the radius and ulna, and treatment with a mini locking plate system as the sole method of fixation. For each patient, data including signalment, time to radiographic union, use of bone graft or other agents, and previous repair attempts were recorded. The outcome and complications were determined from clinical and radiographic follow-up examinations.Results: Fourteen cases with a mean radial width of 4.5 mm (± 0.8 mm) were included into this study. The fractures healed without failure of fixation in all cases. Mean time to adequate radiographic union was 8.4 weeks (± 2.6 weeks). Major complications were not seen in any of the cases, and minor complications occurred in three of the cases. Limb function was graded as ‘normal’ in 10 cases and ‘occasional lameness’ in four cases.Clinical significance: The mini locking system evaluated in this study was an effective treatment method for radial and ulnar fractures in miniature breed dogs with a radial width smaller than 5.5 mm.Supplementary Material to this article is available online at http://dx.doi.org/10.3415/VCOT-16-01-0014.

SummaryObjectives: To describe the use of the Fixin locking plate system for stifle arthrodesis in dogs and to retrospectively report the clinical and radiographic outcomes in six cases.[uni2028]Materials and methods: Medical records of dogs that had arthrodesis with the Fixin locking plate system were reviewed. For each patient, data pertaining to signalment and implant used were recorded. Plate series and thickness, number of screws placed, number of cortices engaged, and screw diameters were also recorded. The outcome was determined from clinical and radiographic followups. Radiographic outcomes assessed included the measurement of the postoperative femoral-tibial angle in the sagittal plane.Results: Six dogs met the inclusion criteria for the study. Mean body weight was 13 kg (range: 3 - 34 kg). Radiographic follow-up (mean: 32 weeks, range: 3 - 52 weeks) was available for all dogs. In one case, an intra-operative complication occurred. In another case, a tibial fracture occurred 20 days after surgery. All arthrodeses healed and no implant complication was detected although all cases had mechanical lameness.Clinical significance: Stifle arthrodesis can be performed successfully using a Fixin locking plate system.

SummaryObjectives: To retrospectively evaluate the stabilization of appendicular fractures in dogs using the Fixin locking plate system.Materials and methods: Medical records and radiographs of dogs with fractures stabilized with the Fixin system in the period from May 2005 to September 2010 were reviewed. For each patient, data pertaining to signalment, the nature of the fracture, implants used, and evidence of fracture healing were recorded. The outcome and complications were determined from clinical and radiographic follow-up examinations. Limb function was evaluated between 40 days and 90 days postoperatively. Owners of pets with complications were contacted by phone for long-term follow-up.Results: Eighty-two fractures in seventy-five dogs met the inclusion criteria for the study. Radiographic re-examinations were carried out between eight days to two years (median 60 days) following surgery. Seventy-three out of 82 fractures (89%) reached union without complications. Major complications were seen in six dogs (7%). Limb function was graded as ‘normal’ in 73/75 (97%) dogs and ‘mild lameness’ in 2/75 (3%) cases.Clinical significance: Despite a modest complication rate, the Fixin locking bone plating system appears to be an acceptable choice of implant for the stabilization of appendicular fractures in dogs.

BACKGROUND: To evaluate clinical and radiological outcome using AO hook locking plate in acute acromioclavicular joint injuries.METHODS: This study was based on patients with Rockwood type 3 or 5 acromioclavicular joint injuries who received surgery with AO hook locking plate from June 2008 until June 2009. Among the 22 patients, 19 of them were male and 3 were female, the mean age was 44.4 +/- 15.57 years (20-72 years) and follow-up period was 15.5 +/- 3.90 months (12-23 months). Preoperatively, postoperatively, and at the final follow-up after the plate removal, both coracoclavicular distances were measured from the anteroposterior radiograph. Also, the Shoulder Rating Scale of the University of California at Los Angeles scores (UCLA scores), the American Shoulder and Elbow Surgeons scores (ASES scores), Constant scores, and the Korean Shoulder Society scores (KSS scores) were measured at the final follow-up to evaluate the function of the shoulder joint.RESULTS: At the time of injury, the mean coracoclavicular distance of the injured side was 17.69 +/- 4.23 mm (9.57-27.82 mm) and the unaffected side was 7.55 +/- 2.20 mm (3.24-13.05 mm). The mean coracoclavicular distance measured postoperatively and at the final follow-up was 6.87 +/- 2.34 mm (4.07-14.13 mm) and 8.47 +/- 2.96 mm (4.37-17.48 mm), respectively. The mean UCLA, ASES, Constant, and KSS scores measured in the final follow-up were 33.5 +/- 1.30 (31-35), 90.8 +/- 8.36 (72-100), 78.6 +/- 8.80 (62-100), and 94.4 +/- 5.08 (84-100) each.CONCLUSIONS: From this short-term research, the surgical treatment using AO hook locking plates in acute acromioclavicular joint injuries is clinically and radiographically satisfying and considered as a useful treatment method.
