Cholesterol crystals were identified in 16 synovial fluids from 12 patients who were seen over the 14-year period 1964 through 1977. Ten of the 12 patients had rheumatoid arthritis of a median duration of 12 years. One patient had ankylosing spondylitis and another had iliopectineal bursitis without other joint disease. The fluids were usually turbid, white, or yellow in color and of thick consistency. When the synovial fluid concentration of cholesterol was determined, it was higher than the serum level. The swollen joints and bursae did not respond favorably to simple aspiration or corticosteroid injections but did to surgical synovectomy. No relationship was found between synovial fluid accumulation of cholesterol crystal and previous intra-articular corticosteroid therapy, serum lipoprotein abnormalities, intra-articular hemorrhage, or generalized arteriosclerosis. The results suggest that local factors are most important in the development of synovial fluid cholesterol crystals, but the exact mechanisms are unknown. The presence of cholesterol crystals in synovial fluid should suggest a severe persistent synovitis, knowledge of which may be helpful in diagnosis and planning therapy.

The calcaneus of normal control patients, and those with rheumatoid arthritis, ankylosing spondylitis, psoriasis, and Reiter syndrome was studied. Pathological abnormalities of the plantar aponeurosis, Achilles tendon, and retrocalcaneal bursa account for the radiographic alterations. In normal individuals, lateral radiographs show the thickness of the Achilles tendon to be not greater than 8 mm; the retrocalcaneal bursa creates a radiolucency which extends at least 2 mm below the superior surface of the calcaneus. In patients with any of these 4 articular disorders, Achilles tendinitis produces thickening of the tendon, and retrocalcaneal bursitis obliterates the normal radiolucency.

Sixty-two hips in fifty-five patients who were considered to be at risk for postoperative heterotopic ossification were randomly divided into two groups: one received a single 800-centigray dose of limited-field radiation and the other, 1000 centigray of limited-field radiation in divided doses. The risk for heterotopic-bone formation was identified on the basis of previously described criteria, which included previous heterotopic ossification after an operation about the hip, hypertrophic osteoarthritis or post-traumatic osteoarthrosis characterized by formation of extensive osteophytes, radiographic evidence of diffuse idiopathic skeletal hyperostosis, ankylosing spondylitis, and male sex. The treatment portals excluded prosthetic surfaces that were intended for biological fixation by ingrowth of bone. At a minimum six-month follow-up, progression of heterotopic ossification had occurred in seven (21 per cent) of thirty-four hips in the first group and in six (21 per cent) of twenty-eight hips in the second group. The ossification had advanced more than one grade in only one hip. Extra-field ossification occurred in fifteen (43 per cent) of thirty-five hips that had not had previous heterotopic ossification. Since the time of the study, the treatment portal has been modified to include the lateral aspect of the greater trochanter, so that the risk of bursitis associated with ossification in this area is minimized. Single-dose limited-field radiation is effective for the prevention of heterotopic ossification, without compromise of early fixation of an uncemented implant.

Tenoxicam administered orally, rectally or parenterally is an effective analgesic and anti-inflammatory agent for the symptomatic treatment of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis and various rheumatic conditions such as tendinitis, bursitis, sciatica, back pain and gouty arthritis. In clinical trials its efficacy is at least equivalent to that of other NSAIDs and it is at least as well tolerated as piroxicam and probably better tolerated than diclofenac, indomethacin and ketoprofen. Compared with many other NSAIDs, tenoxicam offers certain advantages in that it is conveniently administered once daily and dosage adjustment is not required in the elderly or in patients with renal or hepatic impairment.

Heterotopic ossification is a well-recognized complication of total hip arthroplasty. In a retrospective survey of 98 total hip arthroplasties in ankylosing spondylitis performed between 1970 and 1977, 39.8% showed some evidences of heterotopic ossification. Restriction of hip movements was noted in only two. Heterotopic ossification occurred within one year and was higher (64.6%) in patients with bilateral hip replacements if there was evidence of heterotopic bone formation in one hip. The complications were relatively high in hips with previous operations (55%); trochanteric bursitis (50%); and trochanteric detachment (63.3%). No correlation was found between high erythrocyte sedimentation rate and the incidence or extent of heterotopic bone formation.

Between July 1984 and October 1985 the elbow joints of 135 patients were examined by arthrosonography. Of these 97 patients suffered from rheumatoid arthritis, 4 from psoriatic arthritis, 2 from suspected ankylosing spondylitis, 1 from gout, and 27 patients were found to be normal. The equipment used was a Kretz sector scanner Combison 320 and a Siemens Sonoline SL linear scanner. The examination was divided into three parts: longitudinal and transversal scans of the fossa olecrani, the fossa coronoidea and fossa radii. We found, that inflammation of the elbow joint has to be evaluated separately for each part of the joint. The more intense the inflammation, the more certain diagnosis becomes. Bursitis and rheumatoid nodules could be separated sonographically. Also synovialitic complications such as of the bone and the development of synovial cysts could easily be recognized. These arthrosonographical findings are a valuable help in the diagnostics of rheumatic diseases. Their interpretation, however, requires the input of all clinical data.

A case of bilateral deep infrapatellar bursitis is reported in a 19-year-old man suffering from juvenile ankylosing spondylitis and surgically treated for bilateral tibial tuberosity enthesopathy. In addition to erosive non-specific bone remodelling the excised specimens showed, in the bursa, synovial layer hyperplasia with mild subintimal inflammatory cell infiltration, i.e. changes similar to those of synovitis in ankylosing spondylitis. The respective roles of the inflammatory "terrain" and of local shearing stress are discussed.

Eighty-six hips in eighty-five patients who were considered to be at risk for heterotopic ossification following a total hip arthroplasty were prospectively randomized or assigned to one of two treatment groups that received a single 800-centigray dose of limited-field radiation either preoperatively (Group I) or postoperatively (Group II). The risk factors for postoperative heterotopic ossification included previous heterotopic ossification following an operation about the hip, hypertrophic osteoarthrosis or post-traumatic osteoarthrosis characterized by the presence of extensive osteophytes, radiographic evidence of diffuse idiopathic skeletal hyperostosis, and ankylosing spondylitis. The hips in Group I were irradiated within 6.1 hours before the operation and those in Group II, within 51.3 hours after the operation. Either extra-field ossification or heterotopic ossification was observed in forty-one (48 per cent) of the eighty-six hips, thereby confirming the high risk for the population in this study. After a minimum duration of follow-up of six months, thirty-seven (76 per cent) of the forty-nine hips that had been treated with preoperative irradiation exhibited no new heterotopic ossification and eleven, progression to grade-I or II ossification. The remaining hip in that group was in a woman who had Paget disease as well as previous grade-IV (ankylosing) heterotopic ossification about the ipsilateral hip; heterotopic ossification progressed from grade II on the radiographs made immediately after the index revision procedure to grade III at the most recent follow-up assessment. Of the thirty-seven hips that had been treated with postoperative irradiation, twenty-seven (73 per cent) exhibited no new heterotopic ossification and nine had progression from grade-0 to grade-I ossification. The remaining hip in that group was in a man who had Parkinson disease and previous grade-III ossification about the ipsilateral hip; heterotopic ossification progressed from grade III immediately post-operatively to grade IV at the time of the most recent evaluation. Extra-field ossification was identified in twelve (24 per cent) of the forty-nine hips that had been irradiated preoperatively compared with three (8 per cent) of the thirty-seven hips that had been irradiated postoperatively (p = 0.05). Extra-field ossification was not associated with clinical symptoms of bursitis of the greater trochanter in any hip. Three of the ten hips that had a revision operation subsequently had a non-union of the greater trochanter; all three had been treated with preoperative irradiation. The findings of the present study suggest that pre-operative irradiation is effective for the prevention of heterotopic ossification following total hip arthroplasty and that it eliminates the discomfort and morbidity that are associated with conventional postoperative treatment. Furthermore, the efficacy of preoperative irradiation suggests that osteogenic precursor cells that are active in this process are derived from the local tissues within the operative field rather than from distant blood-borne cell lines.

Reactive arthritis (ReA) is an aseptic form of articular inflammation induced by infections mainly localised in the gastrointestinal (enteroarthritis) or urogenital (uroarthritis) tracts. The bacteria principally involved as causative agents are Chlamydia, Salmonella, Shigella, Campylobacter and Yersinia. The clinical picture is usually characterised by a mono-oligoarthritis of the lower limbs. Axial involvement is possible and extra-articular manifestations such as enthesitis, tenosynovitis, bursitis and dactylitis are frequent. NSAIDs and sulfasalazine are still the drugs most commonly used in the treatment of ReA. Steroids are administered when inflammatory symptoms are resistant to NSAIDs. Experiences with other DMARDs (disease modifying antirheumatic drugs) such as azathioprine, methotrexate and cyclosporin, have been sporadically reported and they can be employed in patients that are unresponsive to the more usual medicaments. The intake of antibacterials (tetracyclines) may be useful in uroarthritis but have not been so successful in enteroarthrits. In more aggressive cases, or when ReA evolves towards ankylosing spondylitis, TNF-alpha blockers could represent an effective choice.

The objective of this study was to determine tendon involvements and enthesal abnormalities in patients with rheumatoid arthritis (RA) using high-resolution ultrasonographic images and to compare the findings with those seen in patients with ankylosing spondylitis (AS) and healthy controls. A total of 24 patients with RA, 18 with AS, and 20 healthy controls matched by age and body mass index (BMI) were included in the study. All of the patients and controls underwent clinical and ultrasonographic examinations of both lower limbs at five enthesal sites (superior and inferior pole of the patella, tibial tuberosity, Achilles tendon, and plantar aponeurosis) and both upper limbs at two tendon sites (tendons of m. biceps brachii and supraspinatus at the shoulder). High-resolution ultrasonographic examinations were performed to detect bursitis, structure thickness, bony erosion, and enthesophyte. An ultrasonographic score of lower limb enthesitis was calculated using the Glasgow Ultrasound Enthesitis Scoring System (GUESS) in all patients. Tendon involvements and enthesal abnormalities were found significantly more often in the RA group than in controls (p<0.05 to <0.001), but were not found to be different from the AS group (p>0.05). On clinical examination 67 of 336 (19.9%) tendon and enthesal sites were abnormal and on ultrasonographic examination 130 of 336 (38.2%) sites were abnormal in RA patients. The most frequently affected enthesal sites in the lower limbs were suprapatellar, infrapatellar, and Achilles tendon in both the RA and AS groups. The tibial tuberosity was less affected in both groups, and involvement of the plantar aponeurosis was not different from the controls. A statistically significant correlation was found between the Ritchie articular index and GUESS (r=0.578, p=0.008). Tendon involvements and enthesal abnormalities in RA patients were found more often than had been estimated. Further studies are required to validate our results.
