OBJECTIVE: To compare heat generation and mechanical bone damage for tapered and cylindrical transfixation pins during drilling, tapping, and pin insertion in equine third metacarpal bones. SAMPLE 16 pairs of cadaveric equine third metacarpal bones.
Internal Fixation
Category: Equine - Internal Fixation
OBJECTIVE: To report on a series of 4 horses with supraglenoid tubercle fractures repaired with locking compression plates.
STUDY DESIGN: Case series.
ANIMAL: Four horses ranging in age from 6 weeks to 20 months and weighing from 121 to 425 kg with supraglenoid tubercle fractures of 1 day to 6 weeks in duration.
Category: Equine - Internal Fixation
OBJECTIVES: To describe the outcome, clinical findings, and complications associated with the use of the locking compression plate (LCP) for various types of ulnar fractures in horses.
STUDY DESIGN: Retrospective case series.
SAMPLE POPULATION: Client owned horses (n = 18).
METHODS: Medical records, radiographs, and follow-up for horses having an ulnar fracture repaired using at least 1 LCP were reviewed. Fifteen of 18 horses had fractures of the ulna only, and 3 horses had fractures of the ulna and proximal radius.
Category: Equine - Internal Fixation - Traumatology
REASONS FOR PERFORMING STUDY: There are no reports on the configuration of equine central tarsal bone fractures based on cross-sectional imaging and clinical and radiographic long-term outcome after internal fixation.
OBJECTIVES: To report clinical, radiographic and computed tomographic findings of equine central tarsal bone fractures and to evaluate the long-term outcome of internal fixation.
STUDY DESIGN: Retrospective case series.

OBJECTIVE: To describe the surgical treatment outcome of cervical fractures in 3 horses.

OBJECTIVE: Mechanical evaluation of a novel screw position used for repair in a type III distal phalanx fracture model and assessment of solar canal penetration (SCP).
STUDY DESIGN: Experimental study.
SAMPLE POPULATION: Disarticulated equine hooves (n = 24) and 24 isolated distal phalanges.

REASONS FOR PERFORMING STUDY: An in-depth review of dynamic compression plate (DCP) fixation of propagating medial condyle fractures of the third metacarpus or metatarsus has not been previously reported.
OBJECTIVES: To describe the technique, evaluate short-term outcome and long-term race performance of racehorses that underwent DCP fixation for repair of propagating or spiralling medial condylar fractures of the third metacarpal (McIII) or metatarsal (MtIII) bone.
STUDY DESIGN: Retrospective case series.

The objective was to compare the degree of cartilage destruction obtained with three different drilling techniques for minimally invasive arthrodesis of the equine pastern joint. Three drilling techniques were randomly tested on 36 cadaver distal limbs (six front and six hind limbs in each group).

Objective
To compare the biomechanical properties of a 5-hole 4.5 mm narrow locking compression plate (LCP) and 5-hole 4.5 mm narrow dynamic compression plate (DCP) for equine proximal interphalangeal (PIP) joint arthrodesis.
Study Design
Experimental mechanical study.

Objective: To compare the biomechanical properties of a hybrid locking compression plate (LCP) construct with the compression screw technique as a treatment for transverse mid-body proximal sesamoid bone fractures. Methods: Ten paired forelimbs from abattoir horses were used. The medial proximal sesamoid bone of each limb was osteotomized transversely and randomly assigned, to either repair with a two-hole 3.5 mm LCP or a 4.5 mm cortical screw placed in lag fashion. Each limb was tested biomechanically by axial loading in single cycle until failure.
