In the knee, involvement is mainly synovial, with local extension eroding the bone. Pure tuberculous osteitis is rare, with a few occasional reports. Patella tuberculosis is extremely rare. We report the case of patella tuberculosis with 7-years decline. A 10-years old boy suffered from knee siftness and pain. The patient had correct BCG vaccination. Clinical examination was relatively unrevealing, with tenderness on palpation of the medial joint surface of the patella, patellar crepitation, and slight effusion. On standard X-ray, the lateral view showed a circumferential rosette form with a light peripheral halo. The patient underwent open surgery with a medial parapatellar approach and arthrotomy. Joint fluid was sampled. Direct exploration of the medial side of the patella found soft but continuous cartilage on palpation. The histoligical examination confirmed the diagnosis of tuberculosis. The patient had 12 month anti-tuberculosis chemotherapy. After 7 years of the treatement, the patient had no recurrence and good clinical result. Bone tuberculosis remains difficult to diagnose. Certain locations should always be borne in mind, however rare, in case of pandemic or immunodeficiency. In case of osteolysis, associated with abscess or not, infectious etiology is to be considered and appropriate samples should be taken. Diagnosis is confirmed by histology and bacteriology. The slow evolution of bone tuberculosis requires local treatment of lesions and abscesses. Antibiotherapy regularly ensures recovery.
The prevalence of Staphylococcus infections do not decrease despite the preventive measures. The methicillin-resistant staphylococcus aureus (MRSA) has become a major nosocomial pathogen in community hospitals and responsible 60% of staph infections. Through this study we try to study the epidemiology of methicillin-resistant Staphylococcus in the bone and joint infections. We report a 2-year study retrospectipevelly about 25 cases of bone and joint infection staphilococcus methicillin-resistant. All patients underwent clinical examination, an inflammatory balance and surgical treatment with sampling and bacteriological study of the removal liquid and regular monitoring in all patients. The mean age was 5 years and a half. The sexe ratio was 1.2. mean follow-up of 3 months. One patient had dificit G6PD. The mostaffected area was the capital in 64% of cases. The most common location was at the knee in 32%. The most frequent diagnosis was arthritis followed by osteomyelitis. The antibiotics of the first intention was based on amoxicillin and clavulanic acid associated with an aminoglycoside. It was effective in 75%, and modified according to the results of susceptibility testing in 10 cases. The average duration of antibiotic therapy in IV was ten days. The duration of treatment by oral route relay varies from 10 to 21 days. The apyrexia on day 1 postoperatively was obtained in 73%. The screening of patients at risk of carrying MRSA and isolation should help keep to a minimum cross transmission of infections and the number of non-colonized patients. Place of antibiotic therapy is preponderant and meets pharmacodynamic and pharmacokinetic criteria that must be followed in order to optimize medical treatment.
Bone localization of tuberculosis mainly affects the thoracolumbar spine. The cervical spine is rare. Its diagnosis is often late which exposes to great instability and potentially serious complications. We reported the case of a patient with cervical spine tuberculosis with a rare localisation. A 10-years old boy with no medical history, showed torticolis and high temperature without neurological complication. In the physical examination, he had torticolis and pain in the third, forth and fifth cervical vertebra. The biology showed high CRP 200mg/l. The tomodensitometry of the cervical spine showed a collection of the third cervical spine. The patient took non specific Antibiotics for two months with no radiological improvement. When biopsy was performed, we find an inter apophysis (between C3 and C4) collection. The histological examination confirmed the diagnosis of apophysis tuberculosis. The cervical spine is a rare localisation of the tuberculosis. The apophysis localisation is a more uncommon localisation. The diagnosis is difficult. The histological examination is essential for the diagnosis. The management based on tuberculosis chemotherapy and immobilization started as soon as possible.
Hydatid disease of the bone and soft tissue of the musculoskeletal system is uncommon. The dissemination mode leads to local malignancy with severe prognosis. Tunisia is an endemic area of the disease. Therefore we treated many patients affected the disease. We retrosectivelly reviwed 6 cases of bone hydatid cyst from 1990 to 2010. There were 3 males and 3 females. The mean age was 13 years. The localisation were 03 spinal, 2 in the proximal tibia and & localisation in trochanter. The diagnosis were histoligical in all patient. the mean delay for the diagnosis was 3 years. One patient with spinal localisation had neurological complication paraplegia. All the patient had surgical excision of the hydatid cyst. Ther ewere 3 cases with local recurrence. Because of the poor results with medical treatment, osseous hydatidosis must be treated by a radical operation with wide excision, adapted to each localization. In the main, the prognosis of osseous hydatidosis remains poor, especially with spinal and pelvic localizations, which are the most frequent ones. The prognosis and treatment of osseous hydatidosis belong in the same category as a locally malignant lesion.
