Background: Spondylodiscitis is an uncommon disease, and due to its indolent nature, it is often a late diagnosis. Great stress is put on the etiologic diagnosis, but blood cultures do not always yield positive results. Magnetic resonance imaging (MRI), despite being the diagnostic method of choice, is not always available. Our aim was to characterize the clinical presentation and to identify and check the efficacy of the etiologic and radiological methods of diagnosis of spondylodiscitis used at our hospital.Methods: A retrospective study was conducted in which spontaneous spondylodiscitis cases were identified. The clinical presentation and the results of etiologic and radiological methods of diagnosis were analyzed.Results: Over a period of 5 years, 34 patients fulfilled the inclusion criteria of the study. Regarding days of complaints, we identified a median of 9.5 days (1-547 days), with back pain being the predominant symptom. Fever was present in half the patients. Blood cultures were positive in 16 patients (48.5%). Nineteen patients underwent a computed tomography (CT)-guided biopsy (positive in 7 patients [36.8%]), and 10 patients underwent a surgical biopsy (positive in half of them). Overall, 27 patients (79.4%) had an etiologic diagnosis. The diagnostic work-up consisted mostly of an initial CT scan followed by a confirmatory MRI. Of note, in 5 patients the CT scan did not reveal changes that were later confirmed by MRI. A total of 29 patients (85.3%) underwent an MRI, with 28 being diagnostic.Conclusions: Spondylodiscitis remain a difficult diagnosis. Blood cultures should always be obtained before antibiotic administration and a CT-guided or surgical biopsy should be done if needed. Our results confirm the importance of MRI as the imaging modality of choice and highlight the possibility of false-negative CT scans and the inability of CT to allow for a definitive diagnosis.

PurposeThe relationship between osteotomies around the knee and ankle alignment has been well established. However, little is known about the incidence of new-onset ankle pain after knee osteotomies in the setting of both varus and valgus lower limb malalignments. The purpose of this study is to determine the incidence and characteristics of ankle pain after knee osteotomies; and to clarify the relationship between knee alignment correction, coronal changes sufered by the ankle joint and the development of new-onset ankle pain. Methods Fifty-four lower limbs in 51 consecutive patients, who underwent realignment osteotomies around the knee between April 2013 and October 2020, were retrospectively reviewed. Ultimately, 39 patients (42 knees) were enrolled: 34 had varus deformities and eight had valgus deformities. Ankle pain was assessed according to the Numerical Pain Rating Scale by telephonic interview. The magnitude of alignment correction and the consequent change of both knee and ankle joint lines were analyzed. Correlation between the former and the onset of post-operative ankle pain was evaluated. Patient satisfaction and complications were also noted. ResultsThe incidence of new-onset ankle pain after knee realignment osteotomy was 14%, at a mean follow-up of 55 ± 26 months (range 12-93 months). The mean time between osteotomy and onset of ankle pain was 21 ± 25 months (range 2-60 months). The degree of coronal correction was signiicantly correlated with ankle joint obliquity changes. However, a signiicant correlation with post-operative ankle pain was not found (p > 0.05). Conclusion Fourteen percent of the patients who underwent osteotomies around the knee developed new-onset persistent low-intensity ankle pain. The knee and ankle joint biomechanics are closely related, however, only a small percentage of patients sufer from low-intensity ankle pain which is successfully managed with occasional analgesics. Most osteotomies around the knee seem to require no particular concern for the ipsilateral ankle function.

Resumo Objetivo O objetivo do presente estudo foi avaliar os resultados clínicos e radiográficos da nossa casuística relativamente a osteotomias de encurtamento da ulna, bem como rever sumariamente a patologia, as indicações e as opções cirúrgicas do conflito ulnocárpico. Métodos Realizamos uma análise retrospectiva de pacientes consecutivos que foram tratados com osteotomia de encurtamento da ulna entre janeiro de 2012 e junho de 2017 no nosso hospital. Avaliamos clinicamente a dor, amplitude articular, força da garra e resultados funcionais recorrendo ao questionário quick-DASH. Medimos radiograficamente a variância ulnar pré- e pós-operatória e o encurtamento realizado. Resultados Identificamos oito pacientes operados, tendo sido possível avaliar sete destes. Nesta população, obtivemos uma diminuição da dor (escala analógica visual [VAS, na sigla em inglês] de 7 para 2.6, p < 0,05), uma diminuição do quick-DASH (64 para 28, p < 0,05) e constatamos uma diminuição da amplitude articular ∼ 7° para a flexão (p = 0.2), de 5.5° para a supinação (p = 0,3), bem como diminuição da força da garra para cerca de 86% do lado contralateral (p = 0,07). A variância ulnar foi alterada de uma média de + 5.5 mm para −1.1 mm (p < 0,05). Dois em 8 pacientes (25%) apresentaram sintomatologia relacionada com a placa, sendo que um deles foi submetido a nova intervenção para extração do material. Conclusões A osteotomia de encurtamento da ulna é um procedimento cirúrgico eficaz, tanto no tratamento do conflito ulnocárpico, como na descarga da ulna. Os resultados apresentados vão ao encontro aos demais publicados na literatura, tendo-se obtido bons resultados clínicos e radiográficos.
