Summary
A Border Collie experienced right forelimb lameness due to infraspinatus muscle contracture. Surgical tenotomy of the infraspinatus tendon successfully restored normal gait, resolving the lameness in this canine patient.
Area of Science:
- Veterinary Medicine
- Canine Orthopedics
- Animal Musculoskeletal Disorders
Background:
- A five-year-old Border Collie presented with a three-month history of right forelimb lameness.
- Clinical examination revealed lateral distal forelimb deviation, reduced shoulder mobility, and gait abnormalities.
- Significant muscle atrophy was noted in the infraspinatus, supraspinatus, and deltoideus muscles.
Purpose of the Study:
- To investigate the cause of right forelimb lameness in a Border Collie.
- To determine the efficacy of surgical intervention for infraspinatus muscle contracture.
Main Methods:
- Clinical examination and gait analysis of the affected canine.
- Surgical tenotomy of the infraspinatus tendon was performed.
- Post-operative assessment of gait and limb function.
Main Results:
- Infraspinatus muscle contracture was identified as the cause of lameness.
- Tenotomy of the infraspinatus tendon led to the restoration of a normal gait.
- The surgical intervention effectively resolved the presenting lameness.
Conclusions:
- Infraspinatus muscle contracture is a treatable cause of forelimb lameness in dogs.
- Tenotomy is an effective surgical treatment for this condition.
- Further investigation into the etiology of infraspinatus contracture is warranted.
