Synovial chondromatosis of the elbow causing a mechanical block to range of motion: a case report and review of the literature

We report a unique case of elbow synovial chondromatosis with sudden onset of severe loss of elbow extension and flexion range of motion caused by mechanical block from deposition of chondral fragments in the olecranon and coronoid fossae, respectively. We performed successful arthroscopic surgical treatment of synovial chondromatosis of the elbow. Arthroscopy examination revealed an acutely evolving synovial chondromatosis. Three-year follow-up indicated that arthroscopic removal of loose bodies and partial synovectomy can yield lasting improvement in motion without disease recurrence.

Synovial Chondromatosis of the Shoulder

Articular synovial chondromatosis is a rare disease commonly affecting the knee, hip or elbow, and characterised by the formation of metaplastic cartilaginous foci in the synovium. A case of synovial chondromatosis affecting the shoulder joint is now reported because of the extreme rarity of the disease in this situation.     

Synovial chondromatosis of the elbow in a child

Synovial chondromatosis is cartilaginous metaplasia of mesenchymal remnants of synovial tissue of the joints. Its main characteristic is the formation of cartilaginous nodules in the synovium and inside the articular space (loose bodies). It usually presents between the third and fifth decades and is rare in children. It presents as a mono-articular pathology affecting large joints such as the knee, hip, and elbow. The main symptoms are pain, swelling, and limitation of movements in the affected joint. Diagnosis is made by panoramic radiographs, computed tomography scan, and mainly magnetic resonance imaging and on surgery. The authors describe of synovial chondromatosis presenting in the elbow of an 11 year-old girl which is unreported to the best of our knowledge.     

Primary synovial chondromatosis of the elbow

Very few cases of primary synovial chondromatosis of the elbow have been reported in the literature. This is a study concerning the late outcome of primary synovial chondromatosis in the elbows of 12 patients, 10 men and 2 women, with a mean follow-up of 16 years 10 months. The average age at the time of the initial complaint was 29 years. The histories of 10 patients revealed elbow strain as a consequence of work-related activities. Surgery included removal of loose bodies and partial synovectomy in all patients. A moderate to severe osteoarthritis was found preoperatively in 5 of 12 patients and during follow-up in 7 of 10 patients. The degree of osteoarthritis deteriorated after surgery in 5 of these cases, depending on patient age, length of presurgical history, length of follow-up, and strenuous activities. However, the functional deficiencies were usually moderate and had little significance with respect to the activities of daily living. No recurrence of primary synovial chondromatosis was found.     

Synovial chondromatosis of the shoulder.

Articular synovial chondromatosis is a rare disease commonly affecting the knee, hip or elbow, and characterized by the formation of metaplastic cartilaginous foci in the synovium. A case of cynovial chondromatosis affecting the shoulder joint is now reported because of the extreme rarity of the disease in this situation.

Synovial chondromatosis presenting with peripheral nerve compression--a report of two cases

We report two cases of synovial chondromatosis presenting with peripheral nerve compression syndromes involving respectively the median nerve at the wrist and the posterior interosseous nerve at the elbow. Only one previous instance of nerve compression due to this condition has been described, involving the ulnar nerve at the elbow. In one of our cases the disease process was at an early stage in its natural history and in the other at an advanced stage. The occurrence of nerve compression was related to the site rather than the stage of the disease. Full recovery followed local excision with decompression of the peripheral nerve involved.     

Synovial chondromatosis of the metacarpophalangeal joint of the ring finger

Synovial chondromatosis is an uncommon condition, characterized by multinodular cartilagineous proliferation of the joint synovium. There are only a few case reports of synovial chondromatosis involving the hand in the literature. A case of synovial chondromatosis of the ring finger is reported in this paper.     

Synovial chondromatosis of the shoulder: A case report

Synovial chondromatosis is a rare disease in which cartilaginous masses form in the synovial membrane. The cartilaginous foci may detach to form loose bodies within the joint, which may calcify or ossify. This condition is commonly seen in the knee, hip, or elbow, but is rare in the shoulder (Varma & Ramakrishna 1976, Volpin et al. 1980, Leo & Nocera 1985).     

Vertebral synovial chondromatosis. Report of two cases and review of the literature

Synovial chondromatosis is an uncommon disorder characterized by the formation of multiple cartilaginous nodules within the synovium, most commonly affecting large joints. Its involvement with the spine is rare; only six cases have been reported. The authors describe two patients with synovial chondromatosis involving the cervical spine. In the first case, synovial chondromatosis arose from the left C1-2 facet joint. This patient underwent a two-stage procedure including a posterior approach for tumor resection and occipitocervical fusion as well as a transmandibular circumglossal approach to the anterior craniocervical junction to complete the tumor removal. Interestingly, on histopathological examination, scattered foci of low-grade chondrosarcoma were intermixed within the synovial chondromatosis. To the authors' knowledge, this is the first report of secondary low-grade chondrosarcoma arising in vertebral synovial chondromatosis. In the second case, synovial chondromatosis involved the left C4-5 facet joint. Tumor resection and cervical fusion were performed via a posterior approach. In this report, the authors describe the clinical presentation, radiographic findings, operative details, histopathological features, and clinicoradiological follow-up data obtained in these two patients and review the literature pertaining to this rare entity.     

Giant synovial osteochondromatosis of the acromio-clavicular joint in a child. A case report and review of the literature

Primary intra-articular synovial chondromatosis represents an uncommon condition involving mainly the large joints predominantly of middle-aged adults. We herein document the first case of synovial chondromatosis affecting the acromio-clavicular joint of a 10-year-old girl, characterized by a solitary huge intra-articular osteochondromatous body (giant synovial chondromatosis) that had caused dislocation and deformation of the lateral portion of the clavicle. Successful surgical treatment consisted of removal of the osteochondral body and replacement of the clavicle by fixation with a K-wire.     

Recurrent synovial chondromatosis of the wrist: case report and literature review

Synovial chondromatosis of the wrist is rare. We report the case of a 35-year-old man with synovial chondromatosis of the left wrist with an 8-year follow-up. Frequent recurrences finally resulted in total wrist arthrodesis. A review of the literature produced 24 case reports of synovial chondromatosis of the wrist with only three cases showing recurrence.     

Synovial chondromatosis in a facet joint of a cervical vertebra

STUDY DESIGN: A case report of a cervical facet joint synovial chondromatosis. OBJECTIVES: To correlate the radiologic and histologic features of vertebral synovial chondromatosis with review of the literature. SUMMARY OF BACKGROUND DATA: Only two previous cases of vertebral facet joint synovial chondromatosis were found in a review of the English language medical literature. METHODS: A 39-year-old woman had severe cervical pain associated with neurologic signs and symptoms in the left upper extremity. Computed tomographic and magnetic resonance imaging studies were performed. RESULTS: Imaging studies showed lytic defects in the laminae of C3 and C4, with intermediate T1 and high T2 signal intensities. The diagnostic impression was that of a lymphangioma or synovial cyst. A laminectomy showed synovial tissue in both the C3-C4 facet joint and the lamina bone. Histologic examination disclosed synovial chondromatosis. CONCLUSIONS: Synovial chondromatosis of the vertebral spine is quite rare, this being only the third reported example. Direct invasion of the cancellous bone, as in this case, also is a very uncommon feature of chondromatosis. It is emphasized that when radiologic studies demonstrate a lesion with cartilaginous characteristics within or juxtaposed to a joint, synovial chondromatosis, despite its rarity, should be included in the differential diagnosis, regardless of the anatomic site.     

Synovial chondromatosis of the hand: Three case reports and literature review

Synovial chondromatosis is a rare condition that is probably caused by synovial connective tissue metaplasia. It is very rare in the hand and wrist and because of its low prevalence and nonspecific symptoms, synovial chondromatosis can present diagnostic difficulties for the hand surgeon and may lead to a delay in treatment. We review the literature and report three additional cases of synovial chondromatosis in the hand.     

New-Onset Synovial Chondromatosis After Total Knee Arthroplasty

Total joint arthroplasty is commonly recommended as a definitive treatment for synovial chondromatosis refractory to other treatment. We describe a unique case of synovial chondromatosis developing after total joint arthroplasty in a patient presenting 5 years after total knee arthroplasty for osteoarthritis. This case illustrates that the diagnosis of synovial chondromatosis cannot be excluded in a patient with chronic, painful swelling of a joint, even after total joint arthroplasty.     

Synovial chondromatosis of the ankle joint and elbow in two cases

Two male patients, aged 44 and 88 years, presented with complaints of restricted joint movement, a growing swelling, and pain in the elbow and ankle joints, respectively. Radiographs showed cartilaginous nodules in the affected joints and minimal chondral damage. Magnetic resonance findings were consistent with synovial chondromatosis. Both patients underwent removal of loose bodies by open arthrotomy and partial synovectomy. Histopathologic examination confirmed the diagnosis. No recurrences were detected within a follow-up period of at least a year.     

Diagnosis and Arthroscopic Treatment of Primary Synovial Chondromatosis of the Shoulder

Primary synovial chondromatosis of the shoulder is a rare condition. We present the case of a 24-year-old man with a 6-month history of right shoulder pain and decreased range of motion. Computed tomography and magnetic resonance imaging findings led us to the diagnosis of synovial chondromatosis of the shoulder. Arthroscopy revealed loose bodies in the glenohumeral joint, the biceps tendon sheath, and the subscapularis recess. Active intrasynovial proliferation of the axillary pouch was noted. All loose bodies were removed arthroscopically, and partial synovectomy was performed. Histologic examination confirmed the diagnosis of primary synovial chondromatosis. We recommend arthroscopic treatment for synovial chondromatosis of the shoulder because of low morbidity and early functional return.     

Rezidivierende synoviale Chondromatose im Tarsometatarsalgelenk

Primary synovial chondromatosis is a rare and usually monarticular metaplasia of the synovia. It may recur, but the tendency to malignant transformation is very low. The radiological and histopathological differentiation from low grade chondrosarcoma can be difficult. We present a case report of a 32-year-old male with synovial chondromatosis in the tarsometatarsal joint area, which is an uncommon localization.
