Tuberculous osteitis in limbs. Twenty five case-reports.

Tuberculous osteitis is a rare condition that can be difficult to differentiate from bone tumor on X-ray films. The purpose of this retrospective study was to analyse the epidemiologic, diagnostic and therapeutic aspects of this disorder. Data from 25 patients (13 men; 12 women; mean age = 37) were collected between 1984 and 1993. The source of contagion was traced in 32% of the cases and 24% of patients were known as tuberculous. Patients searched medical attention because of pain in 84% of cases. The greater trochanter was involved in more than 50% of cases. The definite diagnosis was obtained by examination of a surgical biopsy and the anti-bacillary treatment led to recovery in all cases. This study highlights that tuberculosis must be considered when investigating a bone lacuna, all the more so when the greater trochanter is involved, in a country where tuberculosis is endemic.

[Isolated tuberculosis of popliteal cyst. Apropos of a case].

INTRODUCTION: Isolated localization of tuberculosis in the popliteal cyst is an exceptional affection. CASE REPORT: Mr. M.L., 18-year-old black moroccan, was admitted for a painful swelling of the left popliteal cyst, general state alteration and left thoracic pain. Clinical examination found a 5 cm on 3 cm oval tumefaction at the supero-medial part of the left popliteal hollow. No articular effusion was noted. Left knee X ray was normal, while ultrasound examination showed a modified popliteal cyst. Chest X ray showed a pleural effusion. Tuberculine skin test was positive (18 mm). A subtotal resection of the cyst was performed, evacuating 10 ml of thick pus. The histologic examination of the cyst confirmed its tuberculosis origin. In addition the left pleural biopsy confirmed the diagnosis of tuberculosis as well. The antibacillar treatment based on rifampicine, INH and pyrazinamide was given during 6 months. The evolution was favorable at 2 years of follow-up. DISCUSSION: Knee popliteal cyst is frequently an expression of an inflammatory or traumatic affection. The communication between the articular synovium and the serosa bursa of the lateral gastrocnemius is found in 50 per cent of cases, allowing an association of both localizations of tuberculosis. Hamabuchi described for the first time an isolated popliteal cyst tuberculosis in 1990. This case is similar to Hamabuchi's observation. Clinical and radiographical examinations were normal thus excluding a possible dissemination from the knee joint.

[Multifocal bone tuberculosis: apropos of a case].

INTRODUCTION: Tuberculosis of bone is rare (10 to 20 per cent of all skeletal tuberculosis). The multifocal form is exceptional even in endemic countries of tuberculosis. It constitutes less than 5 per cent of all osseous tuberculosis. CASE REPORT: O.H. 34 year-old, Moroccan woman of black race not vaccinated against tuberculosis, with a contagion, complained for a year from scapular pain and weight loss. She noticed that two masses had appeared six months ago. The patient was feverish (38 degrees). The physical exam showed a non inflammatory mass 10 cm wide located in front of the left sacroiliac joint and seeming to be a cold abscess. The radiologic assessment showed a lytic image of the humerus upper extremity, the right iliopubis branch, the left ischium and the left iliac wing. The surgical biopsy of the humerus showed an evolutive caseo-follicular tuberculosis. The nuclear scan of bone found two other localizations in the fourth lumbar vertebra and the ninth left rib. We concluded to a multifocal bone tuberculosis with seven localizations: The upper extremity of both humerus Right pubis Left ischium Left iliac wing 4th lumbar vertebra 9th left rib. The treatment consisted in a specific antibiotic therapy for 6 months associated to the evacuation of the cold abscess. DISCUSSION: Multifocal bone tuberculosis is more frequent in young adults of black race. The beginning of the disease is progressive and the fistulas are the main reason of consultation. The radiologic lesions are not specific and have a geodic shape rimmed with an osteocondensation. Multifocal bone tuberculosis in black african predominate in flat bones. Otherwise in the white race it is located in the long bones extremities. The diagnosis of certitude is based on histologic findings of the peripheric bone lesion. The specific antibiotic therapy leads to the recovery if given early. Short protocols (9 or 6 months) are recently more used with success.

[Triquetro-lunar instability. The role of the radio-styloidian index].

Based on a series of 13 isolated triquetro-lunar instabilities, the authors underline the excess of the radio styloidian index measured radiologically. They found a significant difference (p < 0.001) when comparing this series with a group of 100 normal wrists. A similar comparative study of 13 triquetro-lunar instabilities secondary to perilunar dislocations and of a series of 16 hyperlax wrists did not reveal any significant difference. The same applies to a similar parallel study of the ulnar variance index measurements when comparing the various groups with the control group. After reviewing the mechanism of lesions, and disorders of the wrist's axial forces, caused by changes in the ulnar lengths, ulnar styloid overshooting is designated as a risk factor for isolated triquetro-lunar instabilities. Finally, the authors insist on the necessity of proper reduction of radial low end fractures and detachments, and on the shortening of the long ulna, as a "complementary" procedure when treating isolated triquetro-lunar instabilities.
