Facilities/Technology
Diagnostics
The Gait Analysis Laboratory
The CORL supports and operates a kinetic
gait lab to assess ground reaction
forces produced by dogs and humans
utilizing an AMTI OR6-6 strain
gage-based force plate. The integration
of our forceplate with the current
version of Aquire® allows for the
measurement of the three orthogonal
ground reaction forces: mediolateral (Fx),
craniocaudal (Fy), and vertical (Fz). We
also anticipate the addition of
Video-based Kinematic Gait Analysis in
the near future.
Dual Energy X-Ray Absorptiometry (DXA)
The CORL supports and operates a Hologic
QDR4500A fan beam dual-energy X-ray
absorptiometer for assessment of lean
body mass (muscle), fat, and bone
composition analysis. Our unit's
software allows for a diversity of
animal subject analysis. Sub-regions of
interest can also be identified an
analyzed within the individual. We are
also certified to perform human scans as
well. All serial scans can be compared
to previous scans with an extremely low
covariance factor.
Diagnostic Radiology and Megavoltage
Therapy Services
Imaging services available to the CORL
through the Veterinary Teaching Hospital
at WSU include the use of Radiography,
C-Arm digital Fluoroscopy, Computed
Tomography (CT), Magnetic Resonance
Imaging (MRI), Nuclear Scintigraphy and
Ultrasonography. A linear accelerator is
also available for megavoltage therapy
requirements for oncologic-based
projects.

Material Testing Analysis
The CORL has at its disposal the use of
a complete materials testing laboratory
through the School of Mechanical
Engineering and Material Sciences at WSU.
Indentation, 4-point bending, torsial,
axial compression analysis; both static
and cyclic, can be performed on bone and
composite materials. The CORL can also
perform in vivo and ex vivo cartilage
stiffness analysis using an Artscan®
hand-held indentation unit.
Physical Therapy
Treadmill
Desmo, Woodway® medical grade treadmill
used for: controlled exercise programs
and post surgical rehabilitation
purposes.
Swimming/Recovery Hydropool
The hydropool is used for equine
anesthesia recovery and canine physical
therapy swimming purposes.
Anesthesia/Surgery
Anesthesia
State of the art anesthesia and patient
monitoring equipment. Anesthesia machines
are equipped with
ventilators, anesthetic gases that
include halothane, isoflurane,
desflurane, and sevoflurane. Monitoring
devices include Dynamap®, Doppler,
ECG, direct blood pressure transducer,
HP patient monitoring system, end tidal
volume, blood gases and pulse oximeter.
Surgery
State of the art surgical facilities,
surgical equipment, and surgical
expertise. Complete surgical services for
veterinary-based orthopedic surgery
(including, but not limited to,
arthroscopy, fracture based-implants,
total joint replacement (cemented and
non-cemented) are available.
Current Clinical Recruitment Opportunities:
NO recruitments needed at this time.
Past Research Projects
Spinal Fusion – Evaluation and
comparison of the osteogenic effects
between several interferential
stimulation devices intended for adjunct
use to enhance surgically based spinal
fusion.
Diet and Osteoarthrosis – Evaluation of the effect of a
special dietary formulation on the
clinical expression of osteoarthritis in
dogs with chronic hip dysplasia.
New Bone Forming Products – Evaluation of the osteogenic potential of a new castor
bean polymer to an autogenous cancellous
bone graft in the dog.
Fracture Fixation - A study to compare the
properties of stiffness and strength of
fiberglass/acrylic composite bars to
solid acrylic connecting bars used in
Type I ESF designs in veterinary
orthopedics.
Effects of New Dietary Supplements on
Osteoarthrosis - Evaluation of the effects of a
special dietary formulation on the
clinical expression of chronic
osteoarthritis in dogs.
Obesity and Osteoarthrosis
– Evaluation of the effect of
obesity on the clinical expression of
osteoarthritis in dogs with chronic hip dysplasia.
Treatment of Pain After Orthopedic
Surgery
- Several clinical studies evaluating
the use of a non-steroidal
anti-inflammatory drug on the treatment
of pain associated with cranial cruciate
ligament surgery.
Personnel
Steven A. Martinez, DVM, MS, Diplomate
ACVSCo-director
Dr. Martinez received his Masters of
Science degree in comparative pathology
from the University of California at
Davis in 1984 and received a Doctorate
of Veterinary Medicine degree from the
University of California at Davis in
1985. He completed a small animal
internship at California Animal Hospital
Inc., Los Angeles, in 1986. Dr. Martinez
entered a surgical residency at Michigan
State University, which he completed in
1989. For one year following residency,
he was an assistant professor of small
animal surgery at the University of
Prince Edward Island in Canada. In 1990
he became and assistant professor of
small animal surgery at Michigan State
University until 1997. In 1993 Dr.
Martinez became a Diplomate of the
American College of Veterinary Surgeons.
In 1997, he accepted a position at
Washington State University as assistant
professor of small animal orthopedic
surgery where he is still currently
employed. He also has been an adjunct
professor at Mississippi State
University since the end of 2001.
Research Interests: Arthrology, surgical and non-surgical
treatment of osteoarthritis, orthopedic
patient rehabilitation, gait analysis,
and DXA applications in orthopedics.
James D. Lincoln, DVM, MS
Co-director
Associate Professor, Small Animal
Orthopedic Surgery
Dr. Lincoln received his Doctorate of
Veterinary Medicine from Colorado State
University in 1974. He was in a small
animal practice for three years in
Denver, Colorado, followed by a
residency and graduate program in small
animal surgery at Washington State
University, which he completed in 1979.
Dr. Lincoln became board eligible in
1985 upon completion of requirements set
by the American College of Veterinary
Surgeons.
Research Interests: Gait
analysis, lameness in small animals, hip dysplasia
and pain management.
Kelly Hughes
Research Assistant
Kelly Hughes graduated from WSU in
2003 with a degree in Animal Science
with emphasis in veterinary
medicine. As an undergraduate she
began working in the CORL part time
starting in 2002. After graduation
she returned to Seattle and worked
in private practice for a year but
then returned to the CORL when a
staff position opened. She has been
working in the veterinary field for
7 years now.
