Fracture Fixation and Implants

Authors: Kenneth A Johnson

The development of angle-stable locking screw fixation was the most significant advance in bone plate osteosynthesis of fractures since their original conception of the dynamic compression plate. Some potential advantages of locking plate fixation include the reduced need for accurate anatomical plate contouring, improved construct stability in osteoporotic bone and maintenance of bone blood supply in minimally invasive osteosynthesis.

Objective: The main aim of this study was to compare the biomechanical properties of caudal cervical vertebral stabilization using bicortical transpedicular pins with polymethylmethacrylate (PMMA) versus transvertebral body polyaxial screws and connecting rods with or without an interbody distractor.

Objective: The aim of this study was to evaluate the effect of screw insertion angle and insertion torque on the mechanical properties of a 3.5 fixed-angle locking plate locking compression plate (LCP) and 3.5 variable-angle locking plate polyaxial locking system (PLS).

Objective: To report the configuration, risk factors, fixation methods and complication rates after repair of humeral condylar fractures (HCF) in French bulldogs, and report the presence of humeral intracondylar fissures (HIF) in this population as a possible predisposing factor.

Study design: Retrospective clinical cohort study.

Sample population: Forty-four elbows.

Objectives: The aim of this study was to develop guidelines for the optimal location of drill entry and exit points for insertion of a transcondylar screw across the feline humeral condyle.

Objective: Our objectives were to report complications associated with stabilization of long-bone fractures in cats using a 3.5-mm titanium interlocking nail and to examine the influences of signalment, fracture type and fixation evaluations on the occurrence of complications.

Study design: Retrospective clinical study.

Objective: The objective of this study was to determine the frequency of positive cultures of the surgical gown cuffs among scrubbed personnel prior to and immediately after orthopaedic surgical procedures performed on client-owned dogs.

Objective: To design a precontoured plating system for humeral condylar fracture repair in spaniels with humeral intracondylar fissure (HIF) and quantify accuracy of fit of the system on 3D printed bone models.

Study design: Experimental on 3D printed models.
