Fracture Fixation and Implants

Defining a safe corridor for trans-iliac pin placement in cats
Authors: S Garcia-Pertierra, R L Meeson, Bcy Yeung, G Bedford, M J Pead

Objective: To identify whether a theoretical predictable safe corridor is available in cats for placement of trans-iliac pins without the use of fluoroscopy.

Zürich cementless total hip arthroplasty as a treatment option for capital physeal fractures in dogs: Outcome in 53 cases
Authors: Alejandro Alvarez-Sanchez, Pierre Amsellem, Luca Vezzoni, Aldo Vezzoni

Objective: To review the outcome of dogs that underwent Zürich cementless total hip arthroplasty (Z-THA) for the repair of acute and chronic capital physeal fractures (CPF) and document the CPF-related hip remodeling.

Study design: Retrospective study.

Sample population: Fifty-three Z-THA in 53 dogs.

An experimental study on stress-shielding effects of locked compression plates in fixing intact dog femur
Authors: Xinwen Zhao et al.

Background: In orthopedic application, stress-shielding effects of implant materials cause bone loss, which often induces porosis, delayed bone healing, and other complications. We aimed to compare the stress-shielding effects of locked compression plate (LCP) and limited-contact dynamic compression plate (LC-DCP) in dogs with plate-fixed femurs.

3D-printed, bioactive ceramic scaffold with rhBMP-2 in treating critical femoral bone defects in rabbits using the induced membrane technique
Authors: Jae-Woo Cho et al.

Although autogenous bone grafts are an optimal filling material for the induced membrane technique, limited availability and complications at the harvest site have created a need for alternative graft materials.

Preventing Staphylococcus aureus stainless steel-associated infections in orthopaedics. A systematic review and meta-analysis of animal literature
Authors: Konstantinos Tsikopoulos et al.

Surgical site infection in the presence oforthopaedic implantsposes a significant healthcare and socio-economic burden. In order to assess the potential of various prevention strategies against Staphylococcus-induced stainless steel-associated infections, a review of animal evidencewas designed.

Bone and Cartilage Interfaces With Orthopedic Implants: A Literature Review
Authors: Remigiusz M Grzeskowiak, Jim Schumacher, Madhu S Dhar, David P Harper, Pierre-Yves Mulon, David E Anderson

The interface between a surgical implant and tissue consists of a complex and dynamic environment characterized by mechanical and biological interactions between the implant and surrounding tissue.

Staphylococcal infection prevention using antibiotic-loaded mannitol-chitosan paste in a rabbit model of implant-associated osteomyelitis
Authors: Zoe L Harrison, Leslie R Pace, Madison N Brown, Karen E Beenken, Mark S Smeltzer, Joel D Bumgardner, Warren O Haggard, J Amber Jennings

Antibiotic-loaded chitosan pastes have shown advantages in the treatment and coverage of complex musculoskeletal defects. We added mannitol, previously shown to increase antibiotic susceptibility of biofilm, to an injectable chitosan/polyethylene glycol paste for delivery of antibiotics.

Calcium sulfate antibiotic-impregnated bead implantation for deep surgical site infection associated with orthopedic surgery in small animals
Authors: Lindsay C Peterson, Stanley E Kim, Daniel D Lewis, Matthew D Johnson, Cassio R A Ferrigno

Objective: To report the outcomes and complications associated with antibiotic-impregnated calcium sulfate beads for prevention and treatment of orthopedic-related surgical site infection (SSI) in companion animals.

Study design: Retrospective case series.

Animals: Client-owned cats (n = 2) and dogs (n = 14).

Progressive Loss of Implant Fixation in a Preclinical Rat Model of Cemented Knee Arthroplasty
Authors: Kenneth A Mann, Mark A Miller, Jeffrey K Rossow, Megan E Tatusko, Jason A Horton, Timothy A Damron, Megan E Oest

Aseptic loosening of total knee arthroplasty continues to be a challenging clinical problem. The progression of the loosening process, from the initial well-fixed component, is not fully understood.
