Their use in no way indicates any relationship between Whittemore Enterprises, Inc. These labs provide veterinary surgeons the continuing education credits they need while exposing them to new procedures that shorten the healing time of their patients. The main fracture types were simple transverse 333% or simple oblique 28. We answer the phone on every ring. Using ventral plate fixation is recommended to reduce screw loosening or failure. Our prices are 50% - 75% lower than Synthes® because we are liquidators Synthes® is the registered trademark of Synthes®. Functional outcome was recorded as excellent in 10 dogs, good in two and poor in one.
The ventral plate was stiffer than the lateral plate when a gap was not present. Whittemore is not an authorized agent for Synthes®. No clinically significant change in pelvic canal dimensions measured at 3 locations was identified. Mean time to functional union was 7. Complications occurred in 12 animals 19% and plate failure occurred in 3 5%. Synthes® does not permit commingling of its products. This article is an introduction to the theory and practice of locking plates.
. Please contact Synthes with respect to its warranty policies. The chapter highlights those fractures particularly amenable to repair with locking plates. Locking screw fixation also had significantly higher grades of osteotomy healing, assessed on a mediolateral radiographic view. This chapter discusses the locking plate applications in veterinary orthopedics. While screw loosening can be an incidental finding on routine postoperative radiographs, the potential for catastrophic loss of internal fixation and need for additional surgery is a real concern.
Those associated with complications were double plates and number of cortices engaged above and below fractures. Unlike an independent new development, compatibility with existing surgical techniques, instruments and implants had to be maintained. Data analyzed included breed, age, sex, body weight, body condition score, limb operated, implants used, meniscal status, operative time, and days to recheck. This chapter discusses the locking plate applications in veterinary orthopedics. Some factors in combination lead to challenging surgical repairs and a very small area for safe and effective implant placement.
Fracture instability related to inadequate fracture fixation technique occurred in 4 horses all mature and was always associated with unsuccessful outcome. Conclusions: Ventral plate fixation can be as or more stiff as lateral plate fixation and provides flexible fixation. The fracture region most benefited by the positive attributes of locking plates is the humeral epicondyle and condyle. Minor complications involving implants occurred in 2 hips 5. These surgeons have also contributed to the continued education of our veterinary customers. The rate of screw loosening was significantly lower than previously reported. The Locking Compression Plate was introduced to human orthopaedics at the beginning of the millennium, and subsequently to veterinary orthopaedics a few years later in 2004.
Bicortical screw purchase is recommended to prevent fracture of the cis-cortex and implant pullout. We value your time by distributing surgical instruments, power equipment and suture so you manage fewer vendors and shipments. Supracondylar humeral fractures can be especially challenging due to the complex anatomy of the distal humerus. When the gap was closed in the ventral plate, the stiffness increased until a point that remained constant. We believe being here for our customers is the right thing to do. Signalment, age, body weight, estimated preoperative subluxation and reduction angles, lameness, and complications were evaluated. Three to 5 locking screws were used per plate.
Complications occurred in only 1 hip 7% where pullout of the locking plate—screw construct from the caudal iliac segment occurred because of a fracture of the cis-cortex; the dog made a full recovery after a salvage procedure. Since that time, its use has become common in specialist orthopaedic practice, and a number of other locking plate systems have been developed that are starting to be used in general practice. Additionally, we offer power and instrument repair + service. Pelvic width was measured at 3 locations to evaluate pelvic canal narrowing. The load applied for each of the different configurations studied when a gap of 1° was considered and also when a condition of no gap was considered. At Veterinary Orthopedic implants we strive every day to bring our veterinary customers the selection they need for their demanding practices. Variables were evaluated statistically for effect on complications and functional union.
Post operative incisional infection 4 mature, 3 foals was only managed successfully in 2 foals. Survival rate of horses with open fractures was 12. Results: From both configurations the maximum displacement of the ventral plate with 7 screws without gap had a value of 1. Humerus fractures account for approximately 10% of all long bone fractures in dogs and cats, most of which occur secondary to trauma. Retrospective studies evaluating surgical repair, complications and outcome are necessary to increase knowledge and improve success of long bone fracture repair in the horse.
The aim of the present study was to analyze the difference in stiffness and behavior under loading between a lateral vs ventral plate fixation, with unlocked screws and different gap scenarios, for stabilization of a pelvic osteotomy using finite element analysis. There are limited clinical studies describing the biomechanics of the humerus. Statistically significant factors that affected time to functional union were the presence of multiple injuries and age. The load was applied in a distributed manner on the femur-hip joint contact area in order to simulate the actual behavior of the joint. Cases with adequate follow-up to document a functional union, had surgery performed by an author, had no prior treatment of the fracture s , and with complete operative records were included. It is possible to approach the humerus from lateral, cranial, and medial surfaces.
