Synovial Osteochondromatosis

Osteochondromatoses Synovial


Presentation

  • The authors present the case of a young man with elbow synovial osteochondromatosis associated with ulnar nerve neuropathy.[ncbi.nlm.nih.gov]
Weight Loss
  • There were no systemic symptoms, including weight loss and night sweats, prior to the patient's hospitalization, and the patient had not experienced any previous tumors.[spandidos-publications.com]
Parotid Mass
  • Oral Surgery 28 : 906 – 913 Thompson , K. ( 1986 ) Synovial chondromatosis of the temporomandibular joint presenting as a parotid mass: possibility of confusion with benign mixed tumour .[cambridge.org]
Night Sweats
  • There were no systemic symptoms, including weight loss and night sweats, prior to the patient's hospitalization, and the patient had not experienced any previous tumors.[spandidos-publications.com]
Flushing
  • Pulse irrigation was applied to flush out the residuals. More than 872 of osteochondromatosis were removed out of the hip joint (some small ones were sucked during the operation).[jocr.co.in]
Bouchard's Node
  • Musculoskeletal examination findings were as follows; • Hands: Heberden’s and Bouchard’s nodes in the proximal interphalangeal and distal interphalangeal joints bilaterally.[archivesofrheumatology.org]
Osteopenia
  • RESULTS: At hip radiography, juxta-articular calcified and/ or ossified bodies were seen in 12 of the 15 patients (80%), bone erosion in eight (53%), osteophytes in seven (47%), juxta-articular osteopenia in five (33%) and joint space narrowing in five[ncbi.nlm.nih.gov]
Bone Pain
  • However, there is mild swelling and tenderness around the second metacarpal bone. Pain was aggravated during wrist and finger flexion. An electrodiagnostic study revealed CTS.[ncbi.nlm.nih.gov]
Skeletal Dysplasia
  • Synovial manifestations of skeletal dysplasias have to our knowledge not been described previously but we suggest that synovial osteochondromatosis can be the manifestation of an underlying skeletal dysplasia.[ncbi.nlm.nih.gov]
Elbow Pain
  • There was an increase in the diameter of the right elbow, painful joint movements,and 30-degree extension loss in the physical examination of the patient.[platform.almanhal.com]
Tingling
  • After 2 weeks, the tingling sensation decreased slightly. However mild swelling and tenderness around the second metacarpal bone did not improve. Ultrasonography showed multiple echogenic foci.[ncbi.nlm.nih.gov]

Workup

  • Concerns for possible RA led to a workup.[mdedge.com]
  • Laboratory workup revealed a normal white blood cell count: 7000/mm (normal; 4500-10,000/mm), a normal C-reactive protein: 1.0 mg/L (normal; 0-4 mg/L), and mildly elevated erythrocyte sedimentation rate count: 22 mm/h (normal; 20 mm/h).[sjosm.org]
Joint Space Narrowing
  • RESULTS: At hip radiography, juxta-articular calcified and/ or ossified bodies were seen in 12 of the 15 patients (80%), bone erosion in eight (53%), osteophytes in seven (47%), juxta-articular osteopenia in five (33%) and joint space narrowing in five[ncbi.nlm.nih.gov]
  • Additional radiographic findings include joint effusion and degenerative changes such as joint space narrowing, subchondral sclerosis, and osteophyte formation.[en.wikipedia.org]
  • Plain radiographs of the knee joints revealed joint effusions with multiple rounded intra-articular loose bodies, erosions on the medial aspect of the tibial plateau, tricompartmental joint space narrowing, osteophytes, subchondral cyst formation, heterotopic[archivesofrheumatology.org]

Treatment

  • We describe the surgical treatment and postoperative treatment of patients with synovial osteochondromatosis with moderate signs of secondary osteoarthritis.[ncbi.nlm.nih.gov]

Prognosis

  • The authors review the literature, clinical findings, proposed etiology, classification, ancillary tests, histopathology, differential diagnosis, treatment options, and prognosis. A case report of this rare entity is also presented.[ncbi.nlm.nih.gov]
  • The prognosis is good, but recurrences may occur if the removal is incomplete.[wjso.biomedcentral.com]

Etiology

  • Synovial osteochondromatosis is a benign disease of unknown etiology that involves the articular and periarticular structures. The disorder primarily affects men, and trauma is the most common predisposing factor.[ncbi.nlm.nih.gov]

Pathophysiology

  • The pathophysiology of this condition is multifactorial, and majority of cases of CTS are idiopathic. We report cases of CTS caused by synovial osteochondromatosis (SOC), which has rarely been reported.[ncbi.nlm.nih.gov]
  • Streamline the decision-making process with integrated protocols, classic signs, and ACR guidelines, as well as a design that structures every chapter consistently to include pathophysiology, imaging techniques, imaging findings, differential diagnosis[books.google.de]

Prevention

  • Our advice is to remove all the loose bodies carefully to prevent damage to the prosthesis. During follow-up, special attention should be paid to prevent recurrence of SO.[ncbi.nlm.nih.gov]
  • Surgical removal of loose bodies and synovectomy may relieve symptoms and prevent hip joint degeneration, the sequelae of which can be especially devastating in the younger patient population commonly affected by the condition.[arthritisresearch.us]
