RESUMEN
The number of spine surgeries around the world is increasing in recent years. Each time, new techniques and minimal invasive procedures are developing. However, the incidence of postoperative spinal infections (PSII) ranges from 0.7% to 20%. In cases of infection, identification of the pathogen is essential to apply the appropriate antimicrobial treatment. Most of the usual techniques are based on the recovery of samples from the periprosthetic tissue followed by inoculation in culture media. In the last years, the presence of biofilm-forming bacteria has increased, which has the ability to decrease the sensitivity of the traditional culture method. The application of sonication prior to culture on the rescued inert material, disrupts the biofilm and generates a significantly higher recovery of bacterial growth compared to conventional tissue culture. We present a case series from our service of patients undergoing apparently aseptic lumbar spine revision surgery with positive culture by sonication.
RESUMEN
AIMS: Our objective is to compare the functional results in patients that underwent surgery for recurrent anterior shoulder instability (RAGHI) during the COVID-19 pandemic with remotely-based rehabilitation, to those who had surgery before the pandemic and had in-person rehabilitation therapy. METHODS: A retrospective case series of 68 patients were included and divided into two groups: In person-group and Home-based group. Western Ontario Shoulder Instability Index (WOSI) and Subjective Shoulder Value (SSV) scores were used to evaluate objective and subjective clinical parameters. Time and level of return to sports was studied by the Subjective Patient Outcome for Return to Sports (SPORTS) score. RESULTS: The mean SSV score was 82% (40-100) on the In-Person group compared with 87% (65-100) for the Home-Based group. Results for WOSI score were similar, with an average of 210.42 (90%) for In-Person and 261.45 (88%) for the Home-Based group (p 0.12). Return to sports was carried out in an average of 6.6 (4-16) months for In-Person group, compared to 6.5 (5-8) months for Home-Based. CONCLUSION: Follow-up and rehabilitation methods for patients who underwent surgery for RAGHI, during COVID-19 lockdown, were not significantly (p 0.12) affected on functional and athletic return in comparison to traditional methods according to WOSI scale. LEVEL OF EVIDENCE: IV Retrospective series of cases.
