Canine Sports Medicine Non-responsive Hind-limb Lameness in Agility Dogs:
Iliopsoas Strains tr ider is a two-year-old intact female Border Collie.
Over the past two months Strider had been having difficulty in agility
runs, knocking bars with her hind limbs and slowing down in the weave
poles. The trainer noticed that Strider was reluctant to fully extend her
rear when going over jumps and was navigating with less force in the hind
limbs when weaving. It was also noticed that Strider had a shortened
stride in the right hind limb at a trot and would occasionally off-load
and even toetouch the right hind limb during the stance phase. Strider’s
owner had pulled her out of trials and after two weeks of rest, Strider’s
lameness appeared to improve. When the owner started practicing with
Strider again, she cleared 16 jumps without any problem, but had
difficulty clearing 20 jumps Strider’s jump height is usually 24 .
Strider was once again pulled from training and the owner decided to have
Strider examined by her veterinarian. S By Sherman O. Canapp, Jr., D.V.M.,
M.S., Diplomate ACVS © PHOTOGRAPHY BY LESLEY Strider’s vet performed an
examination, took x-rays of the hips and knees, and performed a Lyme
disease test. The x-rays and blood work were within normal limits and
Strider’s veterinarian stated that it must be an early ACL injury. The
veterinarian prescribed two weeks of Rimadyl non-steroidal antiinflammator
y drug and recommended that the owner continue to restrict Strider to leash
walks only. Unfortunately, Strider had a limited response to two more weeks
of rest and Rimadyl and the owner asked the veterinarian for a referral to
a board certified orthopedic surgeon. Strider was referred to me at our
facility, the Veterinary Orthopedic & Sports Medicine Group VOSM . At
presentation, Strider had a mildly shortened stride in her right hind
limb. During the stance phase Strider would occasionally off-load weight
from her right hind limb to her other side. On physical examination
Strider had mild atrophy quads and hamstrings in the right hind limb when
compared to the left. When the right hip was extended, abducted moved away
from the body , and internally rotated Strider showed signs of discomfort.
When I applied gentle pressure to the iliopsoas muscle, I noted a
significant spasm and trigger points. When pressure was applied to the
iliopsoas’s tendon and point of insertion on the lesser trochanter of
the femur, Strider displayed significant discomfort. The remainder of the
orthopedic and neurological examination was within normal limits. Based on
the history and orthopedic examination I diagnosed Strider with an
iliopsoas strain and recommended rehabilitation therapy laser therapy,
stretching and strengthening, and a home exercise program , medical
management consisting of a muscle relaxant Robaxin , and controlled
activity. Following five days of Robaxin and six weeks of rehabilitation
therapy and controlled activity Strider returned to training with no signs
of lameness or performance issues, including returning to the 24 jump
height. Clean Run | March 07 66 Warning : Unknown : The session id contains invalid characters, valid
