Signalment: Canine, 8yo, M, Border Collie, “Ben”

History: Patient is a competitive herding dog and after a weekend trial, became lame in the left forelimb. He received the treatment below and was recovering well when his right forelimb became painful.

Diagnostics and Exam Findings: The patient had severe pain on the left shoulder extension and abduction. He was diagnosed via musculoskeletal ultrasound with severe subscapularis tendon strain and biceps tendon overuse. After treatment of the left shoulder, pain and lameness in that limb resolved but the right shoulder had significantly increased discomfort which was attributed to his history of medial shoulder instability and osteoarthritis.

PRP Treatment Details: 1.5mls of PRP was injected into the left shoulder joint and 0.5ml of PRP was injected into the left biceps tendon using musculoskeletal ultrasound guidance. 1 ml of PRP in combination with HA was injected into the right shoulder joint 13 weeks after treatment of the L shoulder.

Stance analysis: Stance analysis showed improved weight bearing of the left forelimb. Initially, the left forelimb supported 28% of total body weight (normal is 30%) and 3 days after PRP, was improved at 35%. This improvement sustained with a reading of 36% at a 16wk recheck. The increasing discomfort of the right forelimb was also reflected with initial weight bearing being 30%, but decreasing to 27% after the opposite limb received PRP.

Frequency of treatment: The patient received a single injection of PRP for treatment of both shoulder joints.

Other treatments: The patient participated in therapeutic exercise and chiropractic sessions. He also received Adequan and Cosequin.

Comments: The patient was comfortable during range of motion of both shoulders and no lameness was present. The patient was able to begin reconditioning so he could finish his herding career.
