Temporary work disability following trapezial resection and suspension arthroplasty for thumb carpometacarpal osteoarthritis. / Incapacidad laboral temporal tras cirugía de rizartrosis mediante trapecectomía y artroplastia de suspensión con sutura de alta resistencia.

PURPOSE: The aim of this study is to assess the time to return to work (TRW) in patients undergoing trapezial resection using the Mini TightRope® system at our center and to investigate factors that might delay return to work following this surgery. MATERIAL AND METHODS: A retrospective study was conducted on patients who underwent Trapezial resection and suspensionplasty using the Mini TightRope® system between 2015 and 2016, with a minimum one-year follow-up. Telephone interviews were conducted along with a review of medical records and radiology reports, as well as temporary work disability documents, collecting epidemiological and occupational data. Groups were compared based on age, gender, dominant hand, biomechanical occupational requirements of the patients, and whether they had experienced prior temporary work disability. RESULTS: A total of 36 patients (29 women and 7 men) with an average age of 55.7 years were included. The median time to return to work was 126 days. Self-employed workers re-entered the workforce 72 days earlier on average; workers who had experienced prior temporary work disability had a greater total temporary work disability duration and took 91 days longer to return to work compared to those who had not. CONCLUSIONS: Patients employed by others and those who had experienced prior temporary work disability before the surgery had longer temporary work disability periods. In our study, no differences were observed based on gender, dominant hand, or biomechanical work demands of the intervened patients.

Enfermedad de Sinding-Larsen-Johansson: análisis de factores asociados / Sinding-Larsen-Johansson disease: analysis of the associated factors

Objetivo. Analizar los factores clínicos, etiológicos biomecánicos asociados a la enfermedad de Sinding-Larsen-Johansson (SLJ). Material y método. Estudio de casos-control valorando los siguientes parámetros: edad, sexo, tiempo de evolución clínica, lateralidad, nivel de actividad deportiva, grado radiológico, existencia de patela alta, existencia de retracción de isquiotibiales y aumento de la caída posterior de la tibia. Resultados. Presentamos 15 rodillas en 14 pacientes (un caso de afectación bilateral). El porcentaje de varones es del 85,7% y la edad media de afectación es de 10,86 años (d.t. 1,61). Todos ellos presentaban un nivel de actividad física y deportiva elevado con una duración de los síntomas muy variable (1-36 meses). Sin tendencia clara en cuanto a la lateralidad, la mayoría se incluyen en un grado radiológico tipo ii (53,3%). El análisis de los datos no muestra diferencias significativas (p>0,05) entre los grupos respecto al índice de Caton ni de Insall modificado. En la medición del ángulo poplíteo en las rodillas lesionadas, sí encontramos diferencias significativas (media: 32,50 d.t.:8,90) con respecto al grupo control (17,67; 8,21). La diferencia en la medición del ángulo de caída posterior en las rodillas lesionadas también ha resultado estadísticamente significativo (10,47; 2,82) con respecto a las rodillas de los casos control (8,33; 1,40). Conclusiones. Los pacientes con la enfermedad tienen un aumento de la pendiente tibial y retracción de isquiotibiales respecto al grupo control y esta diferencia es estadísticamente significativa (AU)

Aim. To analyse the clinical symptoms, aetiology and biomechanical aspects related to Sinding-Larsen-Johansson (SLJ) disease. Material and method. A case control study was conducted, analysing the following variables: age, gender, clinical follow up, side of body with the symptoms, sporting activity, radiological stage, presence of patella alta, presence of short hamstring tendons, and increased posterior tibial slope. Results. A total of 15 knees in 14 patients were studied; one case with bilateral disease. The large majority of cases were 85.7% were male, and the mean age was 10.86 (standard deviation 1.61). All of them practised sport and physical activity at a high level with a variable duration of symptoms (1-36 months). There was predominance in side. The majority were radiological grade II (53.3). The data analysis did not show any significant difference (P>.05) between the study groups regarding the Caton and modified Insall indexes. There was a significant difference in the popliteal angle measured in the affected knees (mean: 32.50, SD: 8.9) compared with the control group (mean: 17.67, SD: 8.21). The difference in the posterior slope angle in the affected knees was also statistically significant (mean: 10.47, SD: 2.82) compared with the control (mean: 8.33, SD: 1.4). Conclusions. According to our data, patients have short hamstring tendons and increased posterior tibial slope compared to the control group, and this difference is statistically significant (AU)
