Overview
Infraspinatus tendon-bursa ossification is a rare condition characterized by the calcification and ossification of the infraspinatus tendon and associated bursa, often leading to chronic lameness and pain in affected limbs, primarily observed in veterinary contexts 1.Diagnosis
Clinical Presentation: Perpetual forelimb lameness, pain on palpation over the infraspinatus tendon insertion 1.
Imaging Techniques: Radiographic examination, ultrasonography, and computed tomography are crucial for identifying ossified structures and alterations in tendon integrity 1.
Specific Findings: Ossified structures lateral to the proximal humerus and irregular periosteum changes at the tendon insertion 1.Management
First-Line Treatments: Rest, non-steroidal anti-inflammatory drugs (NSAIDs), and intralesional glucocorticoid injections 1.
Adjunctive Therapies: Physiotherapy and autologous conditioned plasma (ACP) injections into the tendon insertion site 1.Special Populations
No Specific Data: The provided abstracts do not cover management in pregnancy, pediatrics, elderly, or comorbid conditions 12.Key Recommendations
Utilize imaging modalities including radiography, ultrasonography, and CT for definitive diagnosis of infraspinatus tendon-bursa ossification (Evidence: Moderate 1).
Consider intralesional glucocorticoid injections as part of initial treatment, though response may be limited (Evidence: Weak 1).
Incorporate physiotherapy and autologous conditioned plasma (ACP) injections as adjunctive therapies for chronic cases (Evidence: Expert opinion 1).References
