- Benefits of radial distortion correction in arthroscopic surgery: a first experimental study on a knee modelPublication . Duarte, RM; Ferre, NV; Oliveira, AM; Fonseca, FP; Vieira da Silva, M; Correia-Pinto, JBACKGROUND: Lens probes used in arthroscopy typically have a small diameter and wide field-of-view. This introduces strong radial distortion (RD) into the image, ultimately affecting the surgeon's hand-eye coordination. This study evaluates potential benefits of using distortion-free images in arthroscopic surgery. METHODS: Distortion-free images were obtained using RDFixer™ software (Perceive3D, SA) to remove RD in the input video stream. Twelve orthopedic residents performed an arthroscopic task (loose body removal) in a dry-knee model using video with and without distortion. Residents were questioned about image quality, and surgical performance was rated using an adapted Global Rating Scale. RESULTS: A statistically significant improvement of all parameters was observed with distortion-free images. Residents perceived distortion-free images as providing a wider field-of-view and a better notion of relative depth and distance. CONCLUSION: RD correction improved the surgical performance of residents, potentially decreasing their learning curve. Future work will study whether the benefits are observable in experienced surgeons.

- Spinal infection: state of the art and management algorithmPublication . Duarte, RM; Vaccaro, ARINTRODUCTION: Spinal infection is a rare pathology although a concerning rising incidence has been observed in recent years. This increase might reflect a progressively more susceptible population but also the availability of increased diagnostic accuracy. Yet, even with improved diagnosis tools and procedures, the delay in diagnosis remains an important issue. This review aims to highlight the importance of a methodological attitude towards accurate and prompt diagnosis using an algorithm to aid on spinal infection management. METHODS: Appropriate literature on spinal infection was selected using databases from the US National Library of Medicine and the National Institutes of Health. RESULTS: Literature reveals that histopathological analysis of infected tissues is a paramount for diagnosis and must be performed routinely. Antibiotic therapy is transversal to both conservative and surgical approaches and must be initiated after etiological diagnosis. Indications for surgical treatment include neurological deficits or sepsis, spine instability and/or deformity, presence of epidural abscess and upon failure of conservative treatment. CONCLUSIONS: A methodological assessment could lead to diagnosis effectiveness of spinal infection. Towards this, we present a management algorithm based on literature findings
- Técnica Transfisária Parcial para Plastia do Ligamento Cruzado Anterior em Idade PediátricaPublication . Vieira da Silva, M; Duarte, RMWith more and more children participating in competitive sports at younger and younger ages, we have seen an increase in the incidence and diagnosis of intrasubstance ruptures of the anterior cruciate ligament. As in adults, the instability of the ligaments predisposes children to a potential risk of meniscos and chondral injuries with consequent early degenerative alterations. The timely treatment of these injuries is crucial and the surgical technique depends directly on the patient’s physiological age. The authors present a clinical case of the complete rupture of the anterior cruciate ligament in a skeletally immature child, surgically treated by a partial transphyseal technique, with an excellent functional result.
