Experiences using the Fixin locking plate system for the stabilization of appendicular fractures in dogs

Abstract

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.

Biomechanical Comparison of Two Conical Coupling Plate Constructs for Cat Tibial Fracture Stabilization

“…In a retrospective clinical study evaluating the use of Fixin plates in dogs, implant failure occurred in 7 of 82 stabilized fractures. 11 The majority of the fractures were stabilized with the mini Fixin plate system which is the plate series that was evaluated in the current study. The implant failures that occurred in these dogs were characterized by screw breakage (n ¼ 2), plate breakage (n ¼ 4) and plate bending (n ¼ 1).…”

“…2,[7][8][9][10] The conical coupling locking plate system (Intrauma FIXIN; Rivoli, Italy) has been used to successfully stabilize diaphyseal tibial fractures in dogs. 11 This system has a conical bushingscrew head locking mechanism which confers fixed angle stability without altering the plate's thickness. 12 Benefits ascribed to the thin plate profile include ease of contouring, facilitating minimally invasive plating osteosynthesis application and maintenance of implant elasticity that stimulates callus formation.…”

“…12,15 The 2.5 mm conical coupling plate (CCP) would appear to be the most suitable sized implant in this system for stabilizing diaphyseal tibial fractures in cats. 11,12 Our group recently completed a study comparing the biomechanical characteristics of an 8 hole 2.7 mm locking compression plate (LCP) (DePuy Synthes Vet; West Chester, Pennsylvania, United States) to a 6-hole, 2.5-mm CCP and found that LCP constructs were significantly stiffer than the CCP constructs when subjected to both bending and axial loads. 16 In response to the results of that study, the manufacturer developed a prototype CCP (pCCP) to improve the biomechanical profile of the implant (►Fig.…”

“…Increasing plate width adjacent to the screw holes was done to improve plate stiffness as well as mitigate the potential for plate failure through the screw holes. 11 The objective of this study was to evaluate the commercially available and a prototype 6-hole, 2.5-mm CCP applicability for use in stabilizing cat diaphyseal tibial fractures by comparing the stiffness, yield load and load at failure in a cadaveric fracture gap model. Our null hypothesis was that there would be no difference in stiffness, yield load or load at failure between the two constructs.…”

Stabilisation of periarticular fractures and osteotomies with a notched head locking T‐plate

“…More recently, the use of locking plates in the stabilisation of periarticular fractures has gained popularity in the treatment of these fractures in humans . Locking plates utilise a variety of different locking mechanisms to create angle‐stable constructs, whereby the screw head engages with the plate screw hole, and have been reported in the veterinary literature for successful stabilisation of many different fractures and osteotomies . The number of screws required in each fragment is still not clearly defined; however, it has been suggested that adequate stability can be achieved with a minimum of two locking screws per fragment, which may prove advantageous when stabilising small bone fragments.…”
