In VivoBiomechanical Evaluation of a Novel Angle‐Stable Interlocking Nail Design in a Canine Tibial Fracture Model

Abstract

Earlier functional recovery, callus strength and remodeling suggest that the AS-ILN provides a postoperative biomechanical environment more conducive to bone healing than a comparable standard ILN.

Early Clinical Experience with a Newly Designed Interlocking Nail System—Targon® Vet

“…A force of 1.4 Nm was determined to create a rigid locking between the IM nail and the locking screws (unpublished data). As with the hourglass‐shaped ILN, this rigid locking mechanism is another advantage of the TVS over the current ILN systems, which lack a rigid locking mechanism and allow slack to occur . After modification of the torque wrench, no further slippage of the IM nail through the locking screws was observed.…”

“…In addition, there is a mismatch of the locking devices with the hole in the intramedullary (IM) nail in most current ILN systems, causing slack. The latter is defined as the lack of rigid interaction between the locking devices (screws and bolts) and the nail resulting in acute and uncontrolled construct motion . Recently, an hour glass‐shaped ILN was introduced that offers a novel locking mechanism between the nail and the screw‐cone pegs .…”

Tibial fracture repair with angle‐stable interlocking nailing in 2 calves

“…In small animals, long‐bone osteosynthesis with an AS‐ILN has been associated with excellent clinical outcomes and low complication rates . Unlike eccentrically applied plates, the ILN intramedullary location shields the implant from large bending moments.…”

“…Should biomechanical challenges be overcome and clinical outcome improved by using alternative fixation methods, surgical treatment in valuable animals might be considered a viable option. Although interlocking nail (ILN) stabilization has been successful in small animals, to the best of the authors' knowledge the clinical use of an angle‐stable ILN (AS‐ILN) for long‐bone fixation in production animals has yet to be described. This report details the successful treatment and clinical outcome of 2 tibial fractures in calves by using the I‐Loc (Biomedtrix, Whippany, New Jersey) intramedullary fixator.…”

Characterization of the torsional structural properties of feline femurs and surrogate bone models for mechanical testing of orthopedic implants

“…Data were recorded at a sampling rate of 250 Hz, and 10th cycle data were used for statistical analysis. After cyclic testing, specimens were loaded to failure in internal rotation at a displacement rate of 1°/s, in line with previous studies conducted in our laboratory …”
