ABSTRACT
A 55-year-old woman presented to our service with chronic pain in her right shoulder with no history of trauma. Shoulder x-ray and CT scan revealed an enchondroma of the proximal humerus with no associated fracture. The MRI also showed a complete rupture of the supraspinatus and infraspinatus tendons. An arthroscopic transosseous rotator cuff repair without anchors was performed. At 12 months of follow-up, the patient had recovered functionality and the enchondromatous lesion remained stable. Anchorless transosseous arthroscopic repair of a rotator cuff tear may represent a good surgical option for patients whose bone quality makes anchor placement inappropriate, such as in the presence of a benign bone tumor such as enchondroma. Level III of evidence: Level IV; case report.
ABSTRACT
Introducción: La artritis séptica (AS) se define como la infección del espacio articular que afecta cualquier articulación, es más frecuente en niños menores de 5 años y su principal causa es la diseminación hematógena. El diagnóstico etiológico es difícil en niños, logrando aislamiento en menos de la mitad de los casos. Se evaluó el rendimiento diagnóstico de la botella de hemocultivo (BHC) como medio alternativo para la siembra del líquido sinovial comparado con los medios convencionales (MC). Metodología: Estudio de cohorte prospectivo realizado en centro de tercer nivel de 2011-2016, niños de 0 a 12 años con diagnóstico clínico de artritis séptica y disponibilidad de las dos muestras tomadas en cirugía. Resultados: Ingresaron 60 pacientes, masculinos 56%, mediana de edad 48 meses y tiempo de síntomas 58 horas (48-192); 33,3% con antecedente de trauma; 30% recibieron antibióticos previos. Articulaciones afectadas: cadera 44%, rodilla 28% y tobillo 18%. En 39 pacientes (65%) se tomaron hemocultivos; de estos 19 (49%) fueron positivos, todos para S. aureus. Se obtuvo confirmación en líquido sinovial por cualquier método en 27 pacientes (45%), positivos en ambos 21,6%, en MC 13,3% y en BHC 10%, los microorganismos más frecuentes SAMS 21,6%, SAMR 8,3%, S. pyogenes 3,3%, SEMR 3,3%, S. pneumoniae 1,6%, N. meningitidis 1,6%, no se aisló K. kingae. El tratamiento antibiótico más utilizado fueron los betalactamicos, mediana de estancia 18(12-25,5) días, mortalidad del 3,3%. Conclusión: Las BHC son un complemento al medio sólido convencional y aumentaron la confirmación etiológica de artritis séptica del 35% al 45%.
Introduction: Septic arthritis (SA) is defined as the infection of any joint space; it is more common in children under 5 years and its main cause is hematogenous dissemination. The etiological diagnosis is difficult in children, achieving isolation in less than half of the cases. The diagnostic performance of the blood culture bottle (BCB) was evaluated as an alternative medium for seeding synovial fluid compared to conventional media (CM). Methods: A prospective cohort survey was conducted in a third-level center from 2011-2016, in children aged 0 to 12 years with a clinical diagnosis of septic arthritis and availability of the two samples taken in surgery. Results: 60 patients were admitted, being 56% male, with a median age of 48 months and symptom time of 58 hours (48-192); 33.3% had a history of trauma; 30% received previous antibiotics. Affected joints: hip (44%), knee (28%), and ankle (18%). Blood cultures were taken in 39 patients (65%); of these, 19 (49%) were positive, all for S. aureus. Confirmation in synovial fluid was obtained by any method in 27 subjects (45%), positive in both: 21.6%, 13.3% in CM, and 10% in BCB. The most frequent microorganisms were: MSSA (21.6%), MRSA (8.3%), S. pyogenes (3.3%), MRSE (3.3%), S. pneumoniae (1.6%), N. meningitidis (1.6%). K. kingae was not isolated. The most commonly used antibiotic treatment was beta-lactams. The median of stay was 18 days (12-25.5), with a mortality of 3.3%. Conclusion: BCB are a complement to the conventional solid medium and increased the etiological confirmation of septic arthritis from 35 to 45%.
