    Effect of Warmed Irrigation Solution on Core Body Temperature During Hip Arthroscopy for Femoroacetabular Impingement
    (Elsevier, 2014) Parodi, Dante; Valderrama, Juanjosé; Tobar, Carlos; Besomi, Javier; López, Jaime; Lara, Joaquín; Ilic, Juan
    PURPOSE: To determine the effect of warming arthroscopic irrigation solution on core body temperature during hip arthroscopic surgery in patients with femoroacetabular impingement. METHODS: An analytical, prospective, observational study was performed in a cohort of 166 consecutive patients. All patients underwent hip arthroscopy for treatment of femoroacetabular impingement. Two groups were studied: patients operated on with arthroscopic irrigation solution warmed up to 32°C ± 2°C (89.6°F ± 3.6°F) and a control group comprising patients operated on with irrigation solution used at room temperature. Relevant information was collected regarding the patients (age, sex, body mass index, and blood pressure) and the procedure (volume and temperature of saline solution, pressure of fluid pump, surgery time, and room temperature). Corresponding statistical analysis was performed with STATA 11.0 (StataCorp, College Station, TX), by use of descriptive statistics, parametric and nonparametric tests, and a generalized estimating equation model for repeated measurements. RESULTS: Both groups were comparable in terms of age, sex, systolic and diastolic blood pressure, body mass index, volume of irrigation solution used, and room temperature. The mean age of the cohort was 33 years (range, 14 to 60 years); mean body mass index, 23.7 kg/m(2) (range, 17.2 to 34 kg/m(2)); mean volume of irrigation solution, 26 L (range, 12 to 39 L); mean systolic blood pressure, 97 mm Hg; mean diastolic blood pressure, 51 mm Hg; and mean surgical time, 110 minutes. A decrease in core body temperature by 0.5°C (0.9°F) or greater occurred during the course of surgery in 66% of patients in the control group versus 28% in the warmed-solution group (P < .001). At least 1 core body temperature measurement of less than 36°C (96.8°F) was recorded in 48% of patients in the control group versus 14% in the warmed-solution group (P < .001). The trend toward a decrease in core body temperature was 4 times greater in the control group than in the warmed-solution group (P < .001). CONCLUSIONS: Use of arthroscopic irrigation solution warmed up to 32°C (89.6°F) reduces the risk of a decrease in core body temperature during hip arthroscopy in patients with femoroacetabular impingement. LEVEL OF EVIDENCE: Level II, analytical, prospective, comparative study in a cohort of consecutive patients.

    Management of femoral neck fracture and metallosis after failed hip resurfacing in developmental dysplasia of the Hip. dante parodi sanguesa1 a case report
    (2012) Parodi, Dante; Díaz-Ledezma, Claudio; Schmidt-Hebbel N, Andrés
    Background: Hip resurfacing arthroplasty has been presented as an alternative for management of symptomatic hip osteoarthritis in young patients with developmental dysplasia of the hip. However, complications such as femoral neck fractures may occur, especially in patient with certain risk factors. Clinical case: We present the case of a 44 year-old women with developmental dysplasia of the left hip treated with hip resurfacing. Four years after surgery, the patient consulted at our trauma center with a femoral neck fracture and radiologic signs of mal positioning of the acetabular component. A type-B postnecrotic periprosthetic fracture associated to metallosis due to mal positioning of the acetabular cup was evidenced. We decided to perform a conversion to total hip arthroplasty. Conclusions: The indication of hip resurfacing in patients with DDH has risks of major complications in the short term, such as periprosthetic femoral neck fractures and metallosis. The conversion to THA is not an easy surgical procedure, requiring a careful preoperative plan and an experienced surgical team.

    Osteotomía cervical cuneiforme femoral para el tratamiento de la secuela de epifisiolisis
    (2011) Tobar, C; Parodi, Dante; Besomi, J; Valderrama, J; Moya, L. E.; Mella, C.; Jara, J; López, J
    Osteotomía cervical cuneiforme femoral para el tratamiento de la secuela de epifisiolisis Introducción: La alteración anatómica de la epifisiolisis no tratada, prototipo de la deformidad del pinzamiento femoro-acetabular tipo cam, causa degeneración articular precoz de la cadera. Objetivo: Describir una técnica original de osteotomía cervical cuneiforme (OCC) para reposicionar anatómicamente la epífisis femoral, en la secuela de epifisiolisis. Material y método: Se operaron 7 caderas en 6 pacientes masculinos, con secuela de epifisiolisis severa; edad promedio de 15 anos (13-16), cuyo motivo de consulta fue coxalgia y claudicación ̃ severa de 9,2 meses promedio. Todos con cierre del cartílago fisiario femoral al momento de la consulta. Técnica quirúrgica y resultados: En todos los casos se efectuó una OCC y reposición de la epífisis femoral. Se realizó disección y elevación del periostio cervical para proteger los vasos epifisiarios de la cabeza femoral; a continuación se ejecutó la OCC, se reposicionó la epífisis femoral en la ubicación anatómica y se realizó una osteosíntesis. Se logró una corrección del ángulo eje epifisiario desde 66◦ preoperatorio a 11◦ postoperatorio. El seguimiento promedio fue 37 meses (4-59). Conclusión: La OCC femoral, propuesta en pacientes con secuela de epifisiólisis, es una alternativa de tratamiento, que logra buenos resultados anatómicos y radiológicos en pacientes jóvenes.
