- ItemActividad Sexual en Pacientes con Pinzamiento Femoroacetabular. Revisión Narrativa de la Literatura(2025) Lira Salas, María Jesús; Klaber Rosenberg, Ianiv; Vidal Olate, Catalina Victoria; Mery I., Pamela; Schweitzer Fernandez, Daniel AlbertoIntroducción: El pinzamiento femoroacetabular (PFA) es una causa común de coxalgia en pacientes jóvenes, afectando movimientos de flexión y rotación profunda, incluyendo las actividades sexuales (AS). El objetivo del estudio fue sintetizar la evidencia sobre RS en pacientes con PFA. Métodos: Se realizó una revisión narrativa de la literatura en las bases de datos Pubmed, Scielo, PEDro y Epistemonikos. Se incluyeron estudios primarios sobre relaciones sexuales en pacientes con PFA.Resultados: Se encontraron siete trabajos publicados entre los años 2014-2024 sobre RS en pacientes con PFA. En los estudios publicados, se han descrito dificultades en las RS asociadas al PFA en el 61 a 91% de los pacientes, siendo las causas principales dolor y rigidez, que inician uno a dos meses después de los síntomas. Se han descrito mejoras post-cirugía en el 29% a 89% de los pacientes, con un reinicio de la actividad sexual entre 29 y 48 días. Las posiciones sexuales con flexión y abducción son las que causan mayores dificultades. No se encontró evidencia sobre la evaluación de las RS en pacientes con PFA por parte de los traumatólogos en la práctica clínica (ejemplo: frecuencia, dificultades, dolor, entre otros). Por último, existe escasa evidencia sobre la educación realizada por parte de los especialistas a los pacientes sobre las relaciones sexuales.Conclusión: El PFA impacta significativamente la actividad sexual, con mejoras reportadas tras la artroscopía en un grupo de pacientes. Las RS son un tema poco abordado por los cirujanos tanto en la evaluación de los pacientes, como en su educación.

- ItemDo thoraco-lumbar spinal injuries classification systems exhibit lower inter- and intra-observer agreement than other fractures classifications?: A comparison using fractures of the trochanteric area of the proximal femur as contrast model(2016) Urrutia Escobar, Julio Octavio; Zamora, T.; Klaber Rosenberg, Ianiv; Carmona, M.; Palma, J.; Campos, M.; Yurac, R.Introduction It has been postulated that the complex patterns of spinal injuries have prevented adequate agreement using thoraco-lumbar spinal injuries (TLSI) classifications; however, limb fracture classifications have also shown variable agreements. This study compared agreement using two TLSI classifications with agreement using two classifications of fractures of the trochanteric area of the proximal femur (FTAPF). Material and methods Six evaluators classified the radiographs and computed tomography scans of 70 patients with acute TLSI using the Denis and the new AO Spine thoraco-lumbar injury classifications. Additionally, six evaluators classified the radiographs of 70 patients with FTAPF using the Tronzo and the AO schemes. Six weeks later, all cases were presented in a random sequence for repeat assessment. The Kappa coefficient (κ) was used to determine agreement. Results Inter-observer agreement: For TLSI, using the AOSpine classification, the mean κ was 0.62 (0.57–0.66) considering fracture types, and 0.55 (0.52–0.57) considering sub-types; using the Denis classification, κ was 0.62 (0.59–0.65). For FTAPF, with the AO scheme, the mean κ was 0.58 (0.54–0.63) considering fracture types and 0.31 (0.28–0.33) considering sub-types; for the Tronzo classification, κ was 0.54 (0.50–0.57). Intra-observer agreement: For TLSI, using the AOSpine scheme, the mean κ was 0.77 (0.72–0.83) considering fracture types, and 0.71 (0.67–0.76) considering sub-types; for the Denis classification, κ was 0.76 (0.71–0.81). For FTAPF, with the AO scheme, the mean κ was 0.75 (0.69–0.81) considering fracture types and 0.45 (0.39–0.51) considering sub-types; for the Tronzo classification, κ was 0.64 (0.58–0.70). Conclusion Using the main types of AO classifications, inter- and intra-observer agreement of TLSI were comparable to agreement evaluating FTAPF; including sub-types, inter- and intra-observer agreement evaluating TLSI were significantly better than assessing FTAPF. Inter- and intra-observer agreements using the Denis classification were also significantly better than agreement using the Tronzo scheme.

- ItemHip Fracture in the Elderly(2017) Zamora Helo, Tomás; Klaber Rosenberg, Ianiv; Urrutia Escobar, Julio OctavioHip fractures in elderly patients are the most severe form of fragility fractures. They can lead to significant morbidity and mortality; additionally, they have an enormous economic and social burden. Treatment of hip fractures in elderly patients should be based on a prompt initial evaluation, followed by surgical treatment without unnecessary delays under a collaborative effort of a multidisciplinary team. Postoperative care should be started immediately after surgery, and it must include an intensive rehabilitation, as well as treatment of osteoporosis and any other metabolic imbalance. This review incorporates current literature on initial evaluation and definitive management of hip fractures in the elderly and is intended to assist practitioners of different specialties treating these patients.
