Synovial Osteochondromatosis

Abstract

… The shoulder joint trauma after one to two years usually induces growth of its traumatic separated articular cartilage pieces, which sometime further deteriorates into an uncommon condition termed as SOC (Secondary synovial osteo-chondromatosis). Objectives: Is to determine the secondary osteochondromatosis of shoulder joint by its specific differentiating features in history, skiagram, sonogram, MRI and microscopic findings of tissue of the affected joint. Methods: A male of 34 years with complaint of pain, stiffness and decreased range of movement in left shoulder joint came to an adult orthopedic outdoor unit, Shalimar Hospital, Lahore, Pakistan and admitted in the orthopedic unit 3 for treatment. After physical /clinical examination, Skiagram, sonogram and MRI of the patient's affected shoulder joint were performed by the Radiology department and diagnosed as secondary variety of osteochondromatosis of the shoulder joint. Its nodules excised through arthroscopy were examined histopathologically and found to contain fragments of articular cartilage with ring of calcification. Conclusion: MRI imaging as compared to other medical imaging modalities is more precise in estimating diagnosis of secondary osteochondromatosis. However the diagnosis of this disorder is counter confirmed by presence of loose bodies of hyaline cartilage encircled by calcification lamellae on histopathological examination.
