Magnetic resonance imaging of pathologic conditions of the Achilles tendon.

The advent of magnetic resonance imaging (MRI) has improved imaging of the Achilles tendon. Various pathologic conditions of the Achilles tendon and their MRI characteristics are described. The superior resolution of the tendon provided by MRI can aid in the diagnosis of Achilles tendon disorders, which include complete or partial rupture of the tendon as well as postoperative assessment of tendinous healing, tendinitis and tenosynovitis, and various tumors of the Achilles tendon.

[Nuclear spin tomography in synovitis: experimental and clinical results].

We report our experimental and clinical results in the evaluation of synovitis using magnetic resonance imaging (MRI), and discuss them in the light of the literature. Using rheumatoid arthritis in the rat as a model, we have shown that MRI is more sensitive than physical examination and X-ray for the diagnosis of early soft-tissue inflammation in arthritis. On the basis of MRI findings, in patients with morning stiffness we have found an incidence of tenosynovitis higher than that reported in the literature. Because other groups have demonstrated the usefulness of MRI for the evaluation of inflammatory cartilage and bony lesions in arthritis as well, we anticipate that this method will assume increasing importance in the diagnosis and monitoring of rheumatoid arthritis and related diseases.

[Stress syndrome of the fingers related to rock climbing].

In addition to the well-known common trauma in the practice of rock climbing, free climbing at top level has given rise to a new specific pathology affecting the flexor apparatus of the fingers. The cases of 23 top level climbers (performance level 6a to 8a) have been reviewed. 1/3 of them had severe pain in their fingers caused by traction movements. 1 climber out of 4 were referred to us for the above symptomatology. The diagnosis was either tendinitis or tenosynovitis, and the treatment was always conservative. Understanding the pathogenesis of the conflict between tendon and pulley movements will permit partly to cure these lesions, but our aim should be to prevent them.

[Echography of the flexor tendons of the fingers].

The accuracy of high-resolution real-time ultrasonic examination of the flexor tendons of the fingers was tested in a retrospective study of 27 patients treated surgically. In ruptured tendons (8 cases) the method proved sensitive and specific, except in cases of partial rupture. Ultrasound made it possible to distinguish between extrinsically developed palmar masses (8 cases) and masses involving the tendons (4 cases). A fluid collection inside the tendon sheath was detected in 5 cases of tenosynovitis, without false-positive results. The post-operative follow-up of surgically treated tendons (2 cases) was easier with ultrasound.

Effects of cyclosporine A on reovirus-infected broilers.

The effect of cyclosporine A on reovirus-infected male broiler chickens was studied. Beginning at 1 or 10 days of age, 3 groups of 15 broilers were injected in the pectoral muscle with 50 mg of cyclosporine A (CSA) in oil per kg body weight every 3 days until 28 days. Controls were injected with olive oil. Two CSA-injected groups and one untreated group were orally infected with 1000 TCID50 of reovirus at 1 day of age. Cell-mediated immunity was evaluated at 17 and 24 days by a delayed-wattle-response test to injected phytohemagglutinin (PHA-M). Cyclosporine A and reovirus significantly (P less than 0.001) depressed the wattle response following the first injection of PHA-M but not the second. At necropsy 28 days postinoculation (PI), no gross lesions were apparent. Histologic lesions in birds infected with reovirus were lymphocytic pericarditis and tenosynovitis; synovial cells were hyperplastic, and heterophils and fibrin were in synovial spaces. Thymic medullary diameters were significantly (P less than 0.001) smaller in all CSA-treated birds. Although CSA suppressed cell-mediated immunity somewhat, there were no apparent differences in severity of microscopic lesions among reovirus-infected groups.

[Ultrasonic study of the soft tissues of the hand. II. Tumors and pseudotumors of soft tissues. Preliminary results apropos of 12 surgically treated cases].

Thirty patients underwent a sonographic examination of the hand because of nodular masses. In 12 out of these, the surgical removal exhibited 5 benign tumors (2 giant cell tumors, 1 angioma, 1 lipoma, 1 myoma), 5 pseudo-tumors (1 granulomatous tenosynovitis, 1 nodular tendinitis, 2 sebaceous cysts, 1 synovial cyst) and 2 congenital abnormalities of the lumbrical muscles. Except the lipoma and the nodular tendinitis, all the masses were hypoechoic or anechoic. The major interest of sonography in such a disease is a precise localization of the mass and the description of its connections with the surrounding anatomical structures.

[Ultrasonic study of the soft tissues of the hand. III. Traumatic and inflammatory pathology of the flexor tendons of the fingers].

The accuracy of the high-resolution real-time ultrasonic examination of the flexor tendons of the fingers of the hand has been tested on the retrospective study of 27 patients treated surgically. The method is sensitive and specific in the rupture of the tendons (8 cases), except when the latter is partial. Ultrasound enables the discrimination between palmar masses developed extrinsically (8 cases) and those involving the tendons (4 cases). A fluid collection inside the tendon's sheath has been detected in all the 5 cases of tenosynovitis, without false positive. The post-operative follow-up of operated tendons is easier by ultrasound.

Hand problems in pregnancy.

The most frequently encountered hand disorders in pregnancy are carpal tunnel syndrome and de Quervain's tenosynovitis. Conservative therapy should be initiated to minimize patient discomfort. Appropriate splinting is the cornerstone of treatment in pregnant women. Surgery is usually not indicated in this patient population.

Influence of a 12.5 per cent rapeseed diet and an avian reovirus on the production of leg abnormalities in male broiler chickens.

The incidence of different forms of leg abnormality were recorded in reovirus (S1133) infected and control male broiler chickens fed on a normal commercial diet or one of similar nutritive value containing 12.5 per cent rapeseed meal. Regular serological examination showed that birds remained free from Mycoplasma gallisepticum and M synoviae infection throughout the 10 week period of investigation. Precipitating antibodies to the reovirus were detected in 90 per cent of the infected birds between the third and 10th week after infection. Carotene levels in rapeseed fed groups showed no significant differences between reovirus infected and control birds or between birds with or without clinical signs of leg abnormality. The most frequent and severe leg abnormalities were present in the infected birds fed on the rapeseed diet, followed by those fed on the normal commercial diet. There was a highly significant difference (P less than 0.01) between the number of birds with leg abnormalities in each of these groups and their corresponding control groups. The lesions which were mainly responsible for these differences were tenosynovitis and enlarged hocks. Oral infection with reovirus did not appear to make the birds more susceptible to other types of leg abnormality, although the severest lesions of dyschondroplasia were seen in birds which had been exposed to the dual effects of reovirus and rapeseed diet.

Clinical and radiologic features of primary osteoarthritis of the hand.

An appreciation of the salient clinical and radiologic presentations of osteoarthritis, as well as associated tenosynovial problems (stenosing tenosynovitis and carpal tunnel syndrome), is necessary for effective diagnosis. The treatment of osteoarthritis is predicated upon an understanding of the anatomy and pathomechanics of the disease process. Relevant features of the anatomy of the joints of the hand have been reviewed. The correlation of pathologic abnormalities with their radiologic findings has been presented. The degenerative joint disease termed osteoarthritis affects primarily cartilagenous and osseous tissues, while synovial changes are less pronounced. The characteristics of osteoarthritis of the interphalangeal, carpometacarpal joint of the thumb, and metacarpophalangeal joints of the hand have been reviewed.

Complete tenosynovial adhesions complication of conservative care. Peroneus brevis, extensor carpi ulnaris tendon.

The authors present two cases of completely adhesed peroneus brevis and extensor carpi ulnaris tendon that have failed to respond to extensive conservative therapy. They found that the complete adhesions restricted tendon motion and thus prevented the conservative measures from providing relief. They demonstrate that surgery is a valid treatment for chronic persistent adhesive tenosynovitis that has not responded to conservative measures, resolving pain and restoring full range of motion.

The post-carpal tunnel syndrome. Causes and prevention.

Even after opening the carpal tunnel for median nerve compression 25 percent of patients have persistent symptoms, the so-called post-carpal tunnel syndrome. Analysis of 135 median nerve decompressions carried out for primary carpal tunnel syndrome showed flexor tenosynovitis in the flexor sheaths of the fingers and operation scarring to be the main causes. A different local pathology in the hand can also be responsible for the symptoms, and it is important to diagnose such conditions before median nerve decompression so that correction can be performed simultaneously. This is demonstrated in a series of 31 patients.

Tendon lesions in broiler fowls.

Tendon lesions have been studied in 35 broiler or broiler breeder fowls. Tendon rupture most commonly affected the gastrocnemius and flexor muscles but was also seen in cranial tibial muscles (four cases) and the patellar tendon (one case). In nine birds tenosynovitis, characterised by a marked inflammatory response, was identified. In others, however, rupture occurred without appreciable inflammation and these cases were concluded to be comparable to spontaneous tendon rupture in other species. A traumatic aetiology is suggested in these cases, as other pelvic limb tendons or ligament rupture was a frequent concomitant finding. Degenerative tendon lesions were present but it is uncertain whether such changes are primary or secondary to rupture.

[The wrist joint].

The wrist joint is involved in a great majority of cases of rheumatoid arthritis. Tenosynovitis and synovitis can lead to severe destruction of the joint and to spontaneous ruptures of the tendons. Therefore, early tenosynovectomy and wrist-joint synovectomy are required. At the advanced stage of the disease, arthroplasty is necessary. Arthrodesis is rarely indicated in the treatment of severe wrist destruction in rheumatoid arthritis.

Acquired adult flat foot secondary to posterior tibial-tendon pathology.

Nineteen patients with the clinical diagnosis of dysfunction of the posterior tibial tendon underwent surgical exploration. Four types of lesions were identified: avulsion of the tendon at the insertion (Group I), mid-substance rupture of the tendon (Group II), an in-continuity tear of the tendon (Group III), and no tendon tear, tenosynovitis only (Group IV). These conditions could not be separated preoperatively by clinical or radiographic means. The patients in Group I were treated by reinsertion of the tendon; in Group II, by flexor tendon transfer; and in Groups III and IV, by synovectomy. At follow-up, most patients in Group I reported no improvement, but the patients in Groups II, III, and IV showed both subjective and objective improvement. The signs and symptoms of dysfunction of the posterior tibial tendon are not specific for mid-substance ruptures of the tendon but also can occur with avulsions or synovitis, or perhaps from other, as yet undefined lesions.

The clinicopathological spectrum of non-tuberculous mycobacterial osteoarticular infections.

We studied the clinicopathological features of eight patients in whom a non-tuberculous mycobacterium was unexpectedly isolated from osteoarticular material obtained at operation. Three distinct types of infection with non-tuberculous mycobacteria were found: tenosynovitis, synovitis, and osteomyelitis. Tissue specimens from these sites showed a spectrum of pathological findings, including (1) virtually no inflammation, (2) mild to severe non-specific chronic inflammation, (3) granulomas without necrosis, and (4) caseating epithelioid granulomas that were indistinguishable from those of tuberculosis. In six patients the infection responded well to adequate surgical excision alone. In the remaining two the infection responded to surgical intervention and antituberculous therapy.
