An experimental study of the tensile bonding strength of acrylic bone cement was carried out by using the tubular bones of 12 mongolian dogs. Following observations were made: 1. The later the cementing stage, the weaker was the tensile bonding strength of bone cement. 2. When saline or synovial fluid was interposed between the contact surfaces of the recipient bone and the cement, the tensile bonding strength of bone cement decreased by more than 50% of that when the bonding surface was dry. 3. When the bonded bone was stored in Hartmans solution, the tensile bonding strength of bone cement was reduced to 15–25% of the strength when stored in air.

Synovial cysts of the temporomandibular joint seem to develop by an increase of intraarticular pressure due to trauma or inflammation which causes capsular herniation. However, if inflammatory synovial cysts develop by an increase of synovial fluid into inflammation tissue in the capsule without capsular herniation, a differential diagnosis should include synovial chondromatosis and synovitis. This is a case report of a synovial cyst developed in a capsule of the temporomandibular joint.]]>

PURPOSE: To confirm the pathophysiology and proper treatment of synovial chondromatosis according to preoperative radiographs, intraoperative findings, and postoperative histology. MATERIALS AND METHODS: Twenty one patients with synovial chondromatosis who underwent the removal of loose bodies and synovectomy since 1995 were investigated. Patients were analyzed in terms of various radiologic and histologic findings of osteochondromas and synovium. RESULTS: The joints involved were the shoulder joint in 9, the knee in 7, the hip in 3, and the elbow in 2 patients. Removals of osteochondromas were performed in all patients, and four who had intrasynovial proliferating nodules were treated by partial synovectomy. Histologically, the synovia were hypertrophied, and osteochondromas classifiable as three distinct types: premature, maturing, and matured. Osteochondromas in the synovium were of the premature type. There were no recurrences at an average 39 months of follow-up. CONCLUSIONS: Based on a study of 21 cases of synovial chondromatosis, there appear to be three separate types of this disease: premature, maturing, and matured. Partial synovectomy may be necessary in premature and maturing types with intrasynovial proliferating nodules.

Repair of injured tendon especially is still a difficult problem in hand surgery. The challenge is to restore the gliding mechanism of the tendon. Despite increasing knowledge of tendon healing and subsequently better postoperative result, the problem formation of adhesion between the tendon and its direct surroundings remains. It is now agreed that primary repair of both flexor tendon is the treatment of choice with preservation and resto-ration of the tendon sheath. The flexor tendon sheath plays an important role in flexor nutrition, especially for the volar part of the tendon, by secreting the synovial fluid. Although data to data are indications that it will lead to fewer adhesions. Tendon sheath are sometimes restored by autologous graft. It is excellent management that the tendon sheath and pulley system are restored during tendon repair. The method of minimal injury to tendon sheath and pulley is better than restoration of that. The exploration of divided tendon through wound margin with endoscope minimizes sheath and pulley injuries. The blunt extraction of divided tendon from invisible wound site is a risky method for exploration of tendon. This endoscopic method is less traumatic, causes less pain, and requires a minimal incision. And the patient with endoscopic tenorrhaphy can exercise immediately because less operation site discomport and can be discharged early. The new tenorrhaphy technique using endoscope is expected to give better result than conventional method.

PURPOSE: Leptin may play an important role in the pathophysiology of osteoarthritis. This study investigated whether leptin concentration in synovial fluid is related to the radiographic severity of osteoarthritis. MATERIALS AND METHODS: Synovial fluids were obtained from 29 osteoarthritis patients who underwent knee surgery and 10 who had no abnormality on articular cartilage during arthoscopic examination. The progression of osteoarthritis was classified by Kellgren Lawrence grading scale. The concentrations of leptin was measured with commercial enzyme-linked immnosorbent assay kits. RESULTS: A significant increase in synovial fluid concentrations was observed in osteoarthritis patients (6.7+/-4.1 ng/ml) compared to the control (2.4+/-1.3 ng/ml). Leptin levels were increased with advancing osteoarthritis stage, resulting in the highest level in stage IV patients(10.7+/-4.9 ng/ml; range 4.7-15.8) compared to that of stage I patients (4.0+/-2.0 ng/ml; range 1.2-7.3). In osteoarthritis patients, age showed a significant correlation with leptin concentrations. CONCLUSION: This study shows that synovial fluid leptin concentrations were closely related to the radiographic severity of osteoarthritis, and suggests that the age of patient may influence synovial fluid leptin concentrations during osteoarthritis progression.

The clinical significance of cytoplasmic inclusions(CPI) in synovial fluid(SF) examination was evaluated. We examined SF specimens collected from major rheumatology clinics in the Philadelphia area during the period of January to December 1995. Among 759 patients in the initial study group, 419 cases with established diagnoses and full synovial analyses were included. Their diagnoses and SF analysis results including leukocyte counts, differential counts and wet preparations were collected and analysed. Ninety seven of the 419 SF specimens were found to have CPI. CPI were found in SF from almost all rheumatic diseases. They were most likely to be found in inflammatory arthropathy including rheumatoid arthritis(RA, 46%), juvenile rheumatoid arthritis(JRA, 78%) and psoriatic arthritis(55%). On the contrary, CPI were least common in crystal-induced arthropathy among the inflammatory arthropathy. CPI were found 8 out of 98 gout cases(8%) and 2 among 53 calcium pyrophosphate dihydrate(CPPD) deposition disease(4%). In noninflammatory arthropathy, CPI were found in only 6 cases(6%) out of the 103 osteoarthritis(OA). In RA cases with non-inflammatory SF, 4 of the 20 SF(20%) had CPI while only 6% of OA SF had CPI. OA SF with CPI were all noninflammatory SF. In summary, CPI were a common finding on SF examination. CPI were more likely to be found in inflammatory arthropathy than noninflammatory. Among inflammatory arthropathy, CPI can favor non-crystal arthropathy than crystal arthropathy. Awareness of the presence of CPI is suggested as an addendum to routine SF analysis. Renewed investigation of the several types of CPI may add further to the understanding of joint disease.
