operative treatment of primary Synovial Osteochondromatosis of the hip surgical technique
Journal of Bone and Joint Surgery American Volume, 2007Co-Authors: Youn Soo ParkAbstract:BACKGROUND: Primary Synovial Osteochondromatosis of the hip, a rare benign condition characterized by multiple intra-articular osteochondral loose bodies and Synovial hyperplasia, may result in mechanical symptoms and degenerative arthritis if untreated. The purpose of this study was to report the results of arthrotomy alone or combined with anterior dislocation of the hip to perform synovectomy and removal of loose bodies in patients with this condition. METHODS: We retrospectively reviewed a consecutive series of twenty-one patients (twenty-one hips) with primary Synovial Osteochondromatosis of the hip treated with open surgical debridement. On the basis of the extent of extra-articular involvement as seen on preoperative magnetic resonance imaging, eight of the twenty-one patients underwent synovectomy and removal of loose bodies following anterior dislocation of the hip and thirteen underwent the same procedure with arthrotomy alone. At a mean of 4.4 years postoperatively, the patients were assessed clinically and radiographically with special attention to disease recurrence, osteoarthritis progression, and surgical complications. RESULTS: The mean Harris hip score for the entire series of patients improved from 58 points preoperatively to 91 points at the time of the latest follow-up. Eighteen of the twenty-one patients had a good or excellent clinical result, and seventeen patients were satisfied with the result of the surgery. The clinical scores, patient satisfaction scores, and radiographic grades of osteoarthritis at the time of the latest follow-up did not differ significantly between the group treated with dislocation and the group treated without dislocation. Symptomatic disease recurred in two of the thirteen hips treated with arthrotomy alone and in none of the hips that had undergone dislocation. However, the surgical complication rate was higher in the group treated with dislocation than it was in the group treated without dislocation (p = 0.042). While patients with some signs of mild osteoarthritis at the initial procedure had a higher rate of osteoarthritis progression, severe osteoarthritis requiring arthroplasty had developed in only one patient at the time of follow-up. CONCLUSIONS: At a mean of 4.4 years postoperatively, we found that open synovectomy and removal of loose bodies for the treatment of primary Synovial Osteochondromatosis of the hip is a reliable procedure that can effectively relieve symptoms. Our results also indicated that Synovial Osteochondromatosis may recur in patients with extensive involvement who are treated with synovectomy alone without dislocation of the hip; however, surgical complications are more likely to occur in patients managed with anterior dislocation of the hip and synovectomy. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions to Authors for a complete description of levels of evidence.

Synovial Osteochondromatosis of the retrocalcaneal bursa a case report
Journal of Bone and Joint Surgery American Volume, 1996Co-Authors: Nobuyuki Hashimoto, Kozo OkadaAbstract:Synovial Osteochondromatosis is characterized by the formation of multiple osteochondral nodules arising from metaplasia of the Synovial tissue. The most prevalent sites are the knee, elbow, and hip3,9,11,18,19. The disorder rarely occurs in the ankle or the foot2,17,22,27. Trauma has been implicated but has never been confirmed as a precipitating factor in the development of this condition4,6,10,18,24. We report the rare case of a patient who had previous trauma and in whom Synovial Osteochondromatosis developed in the retrocalcaneal bursa in association with intraosseous lesions of the calcaneus. Magnetic resonance imaging and computed tomography scanning were useful in guiding the decisions regarding the operative approach in this patient who had atypical Synovial Osteochondromatosis. A twenty-year-old male sailor sprained the left ankle in a fall down stairs in May 1989. The whole foot with the exception of the toes was swollen and severely painful, especially on weight-bearing. The patient had less discomfort when he was not standing. Pain was caused by light touch to the region, but it was not localized. He did not have treatment at that time because the injury occurred during a long voyage at sea. One month later, the entire hindfoot was still painful and swollen and the patient consulted a physician. The findings on standard radiographs were normal, and therefore he was managed with decreased activity and analgesics. After one month, the swelling had disappeared and the pain was localized around the insertion of the Achilles tendon. The patient reported that the pain was severe after he had been running and caused him to limp for a few days. He did not need medication for pain continually, but he …

posterior interosseous nerve palsy caused by Synovial Osteochondromatosis of the elbow analyzed by three dimensional reconstruction a case report
Journal of Medical Case Reports, 2018Co-Authors: Koichi Yano, Yasunori Kaneshiro, Kosuke Sasaki, Hideki SakanakaAbstract:Synovial Osteochondromatosis, a benign tumor consisting of cartilage and bone, generally presents as multiple osteochondral or chondral nodules. Peripheral nerve palsy caused by Synovial Osteochondromatosis is rare. Three-dimensional reconstruction based on magnetic resonance imaging shows the specific shape and location of the tumor and its relation to the nerve. We describe a case of posterior interosseous nerve palsy caused by Synovial Osteochondromatosis of the elbow in a 66-year-old Japanese man. A three-dimensional reconstructed image based on magnetic resonance imaging was used to determine the location and shape of the giant tumor, which was composed of bone and cartilage. After surgical resection of the giant tumor and neurolysis of the posterior interosseous nerve, he fully recovered from nerve palsy 9 months postoperatively. There was no recurrence of the lesion 1 year postoperatively. Synovial Osteochondromatosis that causes posterior interosseous nerve palsy has a characteristic morphology and location, that is, a giant tumor located anterior to the humeroradial joint, as revealed by three-dimensional magnetic resonance image reconstruction.

Synovial Osteochondromatosis in bilateral subacromial bursae.
Modern Rheumatology, 2003Co-Authors: Taku Kawasaki, Touru Imanaka, Yoshitaka MatsusueAbstract:We report a rare case of Synovial Osteochondromatosis in bilateral subacromial bursae. A 73-year-old man presented with sudden shoulder pain. Roentgenograms showed a large number of calcifications between the acromial processes, and a greater tuberosity on both sides. Surgery was performed to remove loose bodies from both sides. There were 11 in the right subacromial bursa, and 9 in the left. According to Milgram’s staging system, this case was diagnosed as stage III. A follow-up examination 10 months after the operation found no recurrence, pain, or limitation of the range of motion on either side.

A rare case of giant Synovial Osteochondromatosis of the thigh: A case report.
Medicine, 2019Co-Authors: Shuzhong Liu, Xi Zhou, An Song, Zhen Huo, Yipeng Wang, Yong LiuAbstract:Rationale Giant Synovial Osteochondromatosis of the thigh is a highly unusual disease without standard diagnosis and curative managements so far. Our focus is to report a very rare case of giant Synovial Osteochondromatosis successfully operated by surgical treatment. The management of these unique cases has certain educational significance in clinical practice. Patient concerns A 63-year-old previously healthy man presented to our institution with a 4-year history of continuous progressive hip pain and local numbness of right side in January 2018. One month ago, the patient felt that the above symptoms were aggravated, and the right hip and proximal thigh were significantly swollen. Diagnosis Computed tomography and magnetic resonance imaging of the hip revealed the irregular mass in his right thigh. Post-operative pathology confirmed the diagnosis of Synovial Osteochondromatosis of the thigh. Interventions Considering the large volume of the mass and possibility of malignancy, the patient underwent surgical exploration and complete tumor resection. Outcomes The patient's neurological deficits and symptoms improved significantly after the surgery, and the postoperative period was uneventful at the 1-year follow-up visit. There were no complications associated with the operation during the follow-up period. Lessons Taken together, the lesion's clinical features, imaging results, and pathological characteristics are unique. Synovial Osteochondromatosis of the thigh, although rare, should be part of the differential diagnosis when the patient presents with local pain, numbness, swelling or other symptoms. We recommend surgical treatment for the occupying lesion when the tumor has caused symptoms or neurological deficits.
