Presentation
Incidental finding.
Patient Data
At the level of the body of the pubis, inferior to the pubic crest and lateral to the pubic symphysis, ossification of the proximal insertion of the right tendon of the adductor longus muscle is evident. There is also osteoarthritis of the left hip with narrowing of the joint space, intra-articular loose bodies, bone changes with bone spurs, and a subcapital fracture of the femoral head.
Case Discussion
The adductor longus muscle tendon originates from the inferior part of the pubic bone crest and contains a fibrocartilaginous enthesis 1.
Heterotopic ossification could be an expression of chronic tendinopathy. Calcification of the proximal adductor longus tendon is rare, often following avulsion, with or without a bone fragment, or as a consequence of partial or complete tendon rupture of the origin of the adductor longus muscle, especially in young athletes 2.
