Evaluation of ilial screw loosening after triple pelvic osteotomy in dogs: 227 cases (1991–1999)

Abstract

TPO screw loosening was multifactorial and related to stability of the affected ilium, screw type, and screw position. Placing cancellous screws that do not engage the sacrum in pelvic osteotomy plate positions 1 through 3 may decrease the number of screws that loosen.

Screw Loosening and Pelvic Canal Narrowing After Lateral Plating of Feline Ilial Fractures With Locking and Nonlocking Plates

“…The mean estimate of SI change was higher with DCP than with LPS or dLPS but the variability rendered non‐significance. It has been suggested that increased screw purchase can be obtained by engaging the sacrum through the ilium when applying a lateral bone plate in dogs, especially after pelvic osteotomy . Increased bone purchase might lead to less pelvic canal narrowing.…”

Influence of bone cements on bone-screw interfaces in the third metacarpal and third metatarsal bones of horses

“…The results of the present study supported the findings from previous investigations, which indicate that Mg-cement is a biocompatible bone cement that can considerably improve bone-implant interface bonding and induce osteogenesis Data are reported as mean  SEM (based on 16 screws in each treatment group). [5][6][7] Indeed, in our study, 2 screws backed out of their locations after day 5 and probably at day 7 when swelling over the screws was detected. a For this variable, the value for Mg-cement-treated screws is significantly (P  0.05) different from the value for untreated and Ca-cement-treated screws.…”

“…16,[20][21][22][23][24][25] Depending on the surgical procedure, the incidence of failure varies. [4][5][6][7]10,11,26 Various implant surface configurations, coating methods, and biomaterials have been developed to improve integration between bones and implants. 3 In small animals, screw loosening is a common complication in triple pelvic osteotomies, tibial plateau leveling osteotomies, and fracture repairs.…”

A biomechanical comparison of conventional dynamic compression plates and string-of-pearls™ locking plates using cantilever bending in a canine Ilial fracture model

“…However, interfragmentary compression achieved with DCP constructs may also accelerate healing. This fracture model also does not account for potentially improved screw purchase with engaging the sacral wing, which has been studied previously with conflicting results [9, 10]. …”
